Further, the following explanation merely provides examples in essence and is not intended to limit the present invention, an application of the present invention or an intended user of the present invention.

(27) FIG. 1A and FIG. 1B are schematic view of the medicine packaging apparatus 10 according to this embodiment. The medicine packaging apparatus 10 is configured so that a plurality of first medicine supplying parts 20, a manually distributed medicine supplying part 30, a packaging part 40 and a second medicine supplying part 50 are provided at an apparatus main body 12. Each part constituting the medicine packaging apparatus 10 is configured to be driven and controlled by a control device 200.

(28) As shown in FIG. 1B, the first medicine supplying parts 20 are provided on an inner side of a door 14 provided on the front side of the apparatus main body 12. The first medicine supplying parts 20 are conventionally known and formed by arranging a plurality of medicine cassettes 22 in the apparatus main body 12 along the vertical and horizontal directions. A plurality of medicines are contained in each medicine cassette 22 according to kinds of the medicines (hereinafter, when the word of “medicine(s)” is used, this mainly means a tablet but also contains a capsule medicine or the like). Based on prescription data or the like, the medicines are discharged from the corresponding first medicine supplying part 20 by a predetermined amount.

(29) The manually distributed medicine supplying part 30 is used for setting half-tablet medicines or medicines whose use frequency is low in each area formed in a grid pattern with manual distribution and utilized for packaging these medicines with the packaging part 40. By pulling the manually distributed medicine supplying part 30 toward the near side on the front side of the apparatus main body 12, the manually distributed medicine supplying part 30 is brought into a state that the medicines can be manually distributed.

A fourth driving gear 70a is attached to the rotational axis of the fourth motor 70.

(38) Each of the power supplying parts 72 (electric power supplying parts) is constituted of a terminal or the like which can supply electric power to the side of the medicine cassette 100 when the medicine cassette 100 is attached to the base portion 60 (for example, one of the power supplying parts 72 on the side of the medicine cassette 100 and the side of the base portion 60 may be constituted of a male-type terminal and the other one of the power supplying parts 72 may be constituted of a female-type terminal). With this configuration, it is possible to supply the electric power to the side of the after-mentioned medicine cassette 100 through the power supplying parts 72 when the medicine cassette 100 is attached to the base portion 60.

(39) The cassette locking part 74 is combined with receiving portions 142x, 142x provided on the side of the after-mentioned medicine cassette 100 to constitute a cassette connecting mechanism 73 for locking the medicine cassette 100 attached to the base portion 60 so that the medicine cassette 100 cannot be released. The cassette locking part 74 includes an actuator 76 and an operating part 78. The actuator 76 is used for operating the operating part 78 and can be constituted of a solenoid or the like, for example. The operating part 78 includes a connecting portion 78a, a pivotally moving portion 78b, a support axis 78c and a plurality of engaging pieces 78d, 78d (in this embodiment, the number of the engaging pieces is two). The connecting portion 78a, the pivotally moving portion 78b and the support axis 78c constitute an engaging piece operating mechanism 78e for operating the engaging pieces 78d, 78d.

(40) The connecting portion 78a is a piece-shaped member for connecting the actuator 76 and the pivotally moving portion 78b. Further, the pivotally moving portion 78b is a member to which the support axis 78c is connected and can be rotated around an axial center position of the support axis 78c integrally with the support axis 78c. The support axis 78c is an axial body arranged so as to extend in a direction crossing (in this embodiment, so as to extend in a direction substantially perpendicular to) a width direction of the base portion 60, that is a sliding direction at the time of attaching the medicine cassette 100 to the base portion 60. The engaging pieces 78d, 78d are arranged on the support axis 78c so as to be spaced apart from each other.

(41) The cassette locking part 74 can drive the actuator 76 to pivotally move the pivotally moving portion 78d and the support axis 78c for moving up and down the engaging pieces 78d, 78d. With this configuration, it is possible to allow the engaging pieces 78d, 78d to respectively protrude from or return into openings provided in a bottom-side portion 80 of the base portion 60. With this configuration, it is possible to respectively engage or release the engaging pieces 78d, 78d to the receiving portions 142x, 142x provided on a bottom surface of the medicine cassette 100 attached to the base portion 60.

(42) As shown in FIG. 4, the base cover 65 is constituted of the bottom-side portion 80 and a rear-side portion 82. Guide portions 80a extending in the front-rear direction are respectively formed on both sides of the bottom-side portion 80. A cassette bottom portion 142 of the after-mentioned medicine cassette 100 is guided by inner surfaces of the guide portions 80a. Auxiliary walls 80b further extending toward the upper side are respectively formed on upper-side outer edges of the guide portions 80a. Guide receiving pieces 80c respectively protrude from the auxiliary walls 80b toward the inner side and the cassette bottom portion 142 of the medicine cassette 100 is guided by the guide receiving pieces 80c. Further, a base-side insertion area 80d for allowing the medicine cassette 100 to be easily clipped by inserting fingers from a front-end portion of the medicine cassette 100 is formed in a front-side center of the bottom-side portion 80. Although the base-side insertion area 80d can be formed by a recess, a cutout or the like, the base-side insertion area 80d is formed by a cutout opening in the front side of the medicine dispensing apparatus 55 and concaved from the front side toward the rear side in this embodiment. Further, the openings from which the engaging pieces 78d, 78d of the above-mentioned cassette locking part 74 can protrude are formed in the base cover 65 in the vicinity of a boundary between the bottom-side portion 80 and the rear-side portion 82.

(43) As shown in FIG. 3 and FIG. 4, the first driving gear 64a, the second driving gear 66a, the third driving gear 68a and the fourth driving gear 70a are exposed from the rear-side portion 82. Further, a hopper 82a for guiding the medicines dispensed from the medicine cassette 100 is attached to the rear-side portion 82. In this regard, this hopper 82a may be fixed to the medicine cassette 100. Further, the medicines dispensed into the hopper 82a are detected and counted by the discharged medicine detecting device 82b.

(44) An optical sensor is used as the discharged medicine detecting device 82b and an optical path is set on the lower side than an upper surface of the second rotating body 130 by a predetermined length (for example, 1 mm) as shown in FIG. 4. Namely, when a position of the center of gravity of the medicine is moved from the upper surface of the second rotating body 130 to a drop position, the inclination of the medicine can be detected. With this configuration, in the case of counting the number of the medicines, since it is possible to stop the rotation of the second rotating body 130 at the time of confirming the discharging of the last medicine, it becomes possible to reliably prevent a subsequent medicine from being discharged.

(45) As shown in FIG. 6 and FIG. 7, the medicine cassette 100 is formed by containing the side-wall constituent body 110 in the cassette main body 140, arranging the first rotating body 120 in a lower-end opening portion of this side-wall constituent body 110 and arranging the second rotating body 130 on an outer periphery of the upper-end opening portion of the side-wall constituent body 110. Further, the medicine cassette 100 has a cassette driving mechanism 150, the height restricting body 160, the width restricting body 170 and the like in the cassette main body 140.

The receiving portions 142x, 142x are concave portions which can be respectively engaged with the engaging pieces 78d, 78d of the cassette locking part 74 provided on the side of the base portion 60. The receiving portions 142x, 142x are combined with the above-mentioned cassette locking part 74 on the side of the base portion 60 to constitute the cassette connecting mechanism 73.

(48) The bottom portion cover body 142b is a cover-like member for closing the opening portion of the upper side of the bottom portion main body 142a. A cylindrical body arrangement portion 142d, openings 142e, 142f, 142g, a second rotating body arrangement portion 142h, a sensor arrangement portion 142i, a rotating guide portion 142j and the like are provided on the bottom portion cover body 142b.

(49) The cylindrical body arrangement portion 142d is a concave portion having a size and a shape for enabling the side-wall constituent body 110 to be fitted thereto. The opening 142e is formed in a bottom surface of the cylindrical body arrangement portion 142d. The opening 142e is used for exposing a driving force transmission portion 156 constituting the cassette driving mechanism 150. Further, the openings 142f, 142f are used for respectively exposing a first output gear 152c and a second output gear 154c constituting the cassette driving mechanism 150.

(50) Further, the second rotating body arrangement portion 142h is used for arranging the second rotating body 130. The second rotating body arrangement portion 142h is a concave portion provided so as to surround the cylindrical body arrangement portion 142d on the upper-end side of the cylindrical body arrangement portion 142d. The second rotating body arrangement portion 142h is curved into a shape along an annular outer edge of the second rotating body 130.

(51) The sensor arrangement portion 142i is provided for arranging a transferred medicine detecting body 145 (a transferred medicine detecting device). The sensor arrangement portion 142i is provided at a position adjacent to the outer periphery side of the second rotating body arrangement portion 142h. The sensor arrangement portion 142i is provided in a riding-over side area Y which is described later in detail and provided at an after-mentioned medicine riding-over position X or a position on a downstream side of a transferring direction of the medicines due to the second rotating body 130 with respect to the riding-over position X.

(52) The transferred medicine detecting body 145 is configured to be capable of detecting the medicines in a transfer path to a medicine discharging part 144c after the medicines prepared in the medicine containing part 182 are transferred and placed from the first rotating body 120 onto the second rotating body 130. Although the transferred medicine detecting body 145 may be any device as long as it can detect the medicines, the transferred medicine detecting body 145 can be constituted of a sensor such as an optical sensor, for example.

(53) The rotating guide portion 142j is used for guiding the second rotating body 130 so that the second rotating body 130 can rotate without floating up and with keeping a substantially horizontal posture in a state that the second rotating body 130 is attached to the cassette main body 140. Although the rotating guide portion 142j may be any portion as long as it can prevent the floating of the second rotating body 130, the rotating guide portion 142j is constituted of a concave portion provided at a portion provided to stand for constituting the above-mentioned sensor arrangement portion 142i and on the lower side of the sensor arrangement portion 142i.

(54) As shown in FIG. 7, a front-end portion of the cassette bottom portion 142 extends toward the upper side and is configured so that a display panel 146 (a display device) can be attached to the front-end portion of the cassette bottom portion 142. Although the display panel 146 may be any member such as a liquid crystal panel which can electronically display information, a piece of paper and a resin plate as long as it can display information, an electronic paper is used as the display panel 146 in this embodiment. Here, the electronic paper is a device which requires electric power for rewriting display-contents and does not require electric power in a displaying state. Further, the electronic paper is configured to display a variety of display data containing a name and the number of the medicines to be contained in the medicine cassette 100 based on the prescription data and a patient name or the like if needed. With this configuration, the user can identify the medicines contained in the medicine cassette 100 at a glance. In addition, by displaying the name and the number of the medicines in a rewritable manner, it is possible to flexibly respond to a change of the medicines or the like. Further, even in a case of restocking the medicines, it is possible to progress operations after confirming the contents displayed on the electronic paper.

(55) By the way, the electronic paper requires a little time for rewriting the contents after the display data is inputted. Thus, in this embodiment, a power storage device (not shown in the drawings) such as a rechargeable secondary battery and a condenser or a hand-held type power supply source such as a primary battery is provided and this battery (or the condenser) can be recharged while the medicine cassette 100 is attached to the base portion 60. Further, even if the medicine cassette 100 is removed from the base portion 60 immediately after a signal is inputted to the electronic paper, it is possible to supply the electric power from the power storage device or the like to the electronic paper to rewrite the contents. By operating the cassette locking part 74 to release the locked state during a predetermined time required from the start to the end of inputting the display data, the medicine cassette 100 can be removed from the base portion 60. It is needed to only store the time period until the lock is released in this case in storage means (not shown in the drawings) of the side of the apparatus main body 1 in advance.

(56) As described above, according to the medicine cassette 100 having the above configuration, it is possible to quickly remove the medicine cassette 100 from the base portion 60 when the display data is inputted and perform a restock operation of the medicines and the like even though the electronic paper is used. Since consumed power in the electronic paper is zero in the state that the cassette medicine 100 is removed, it is possible to display the display data without any problems even though the power storage device such as a battery and a condenser is used. Further, it is possible to progress the operations such as an operation for restocking the corresponding medicines according to the displayed contents. In this regard, although the configuration in which the hand-held type power supply source such as a battery is provided is exemplified in this embodiment, the present invention may take a configuration having no power supply source as described above.

The screw axis 162a is provided to stand in a space formed in the cassette body portion 144. The height restricting portion 164 has a first guide plane 164a arranged with being spaced apart from the upper surface of the second rotating body 130 by a desired distance and a second guide plane 164b constituting a part of an outer peripheral surface of a medicine transfer path in a circumferential direction due to the second rotating body 130. A first input gear 162b is integrated with a lower-end portion of the screw axis 162a. The first input gear 162b meshes with the first output gear 152c through the above-mentioned opening 142g. With this configuration, the driving force outputted from the first motor 64 on the side of the base portion 60 is transmitted to the screw axis 162a through the height restricting body driving force transmission portion 152. Further, a screwing position between the male screw formed on the screw axis 162a and the female screw formed on the connecting portion 162 is changed and thus the height restricting body 160 is moved up and down. Then, a position of the first guide plane 164a with respect to the upper surface of the second rotating body 130 is adjusted. As a result, it is possible to take a state that a height through which the medicines transferred in the circumferential direction by the second rotating body 130 can pass is restricted by the height restricting body 160.

(62) Further, an auxiliary piece 164c is attached to an upper surface of the height restricting portion 164 so that the auxiliary piece 164c can pivotally move around a support axis. The auxiliary piece 164c is biased so as to stand up from the upper surface of the height restricting portion 164 by a spring (not shown in the drawings) provided on the support axis. With this configuration, when the height restricting body 160 is moved to the lower side, the auxiliary piece 164c can be stood up by bias force of the spring to prevent the medicines from entering into a clearance caused between the upper surface of the height restricting portion 164 and a lower surface of the cover body 102.

(63) As shown in FIG. 12 and FIG. 13, the width restricting body 170 has a first guide plane 172 gradually curved toward the outer diameter side along the outer periphery of the second rotating body 130 and a flat second guide plane 174 continued to the first guide plane 172. A first axis member 176 and a second axis member 178 are arranged on the outer diameter side of the first guide plane 172. A driving gear 176a is provided at an upper-end portion of the first axis member 176 and a second input gear 176b is provided at a lower-end portion of the first axis member 176. The driving gear 176a meshes with a driven gear 178a provided at one end portion of the second axis member 178. Further, the second input gear 176b meshes with the second output gear 154c through the above-mentioned opening 142f. Further, a male screw (not shown in the drawings) is formed on the other end portion (on the opposite side with respect to the driven gear 178a) of the second axis member 178. The other end portion of the second axis member 178 is screwed with a female screw of a female screw member 170a integrated with the width restricting body 170.

(64) When the first axis member 176 normally or reversely rotates, the second axis member 178 rotates through the driving gear 176a and the driven gear 178. Along with this, the width restricting body 170 moves in the axial line direction of the second axis member 178. By switching a rotational direction of the first axis member 176, it is possible to reciprocate the width restricting member between a width-expanded position shown in FIG. 12 and a width-narrowed position shown in FIG. 13.

(65) In this regard, in this embodiment, both of the height restricting body 160 and the width restricting body 170 are provided on the side of the cassette body portion 144 and both of the height restricting body driving force transmission portion 152 and the width restricting body driving force transmission portion 154 are provided on the side of the cassette bottom portion 142. Further, the coupling and the transmission of the driving force between the height restricting body 160 and the height restricting body driving force transmission portion 152 are achieved by meshing the first output gear 152c with the first input gear 162b. The coupling and the transmission of the driving force between the width restricting body 170 and the width restricting body driving force transmission portion 154 are achieved by meshing the second output gear 154c with the second input gear 176b. Further, these first output gear 152c and second output gear 154c are arranged outside the cassette bottom portion 142 with being exposed from the openings 142g, 142f respectively.

(66) As described above, the first output gear 152c and the second output gear 154c are arranged outside the cassette bottom portion 142. Thus, the first input gear 162b and the second input gear 176b respectively meshed with these output gears can be removed from the cassette bottom portion 142 by lifting up the cassette body portion 144 in a state that the first input gear 162b and the second input gear 176b are attached to the cassette body portion 144. Namely, the medicine cassette 100 is configured to enable the cassette bottom portion 142 and the cassette body portion 144 to be separated from each other even in a state that the height restricting body 160 and the width restricting body 170 are not separated from the cassette body portion 144 and the bevel gears 152f, 152g are respectively meshed with the bevel gears 154f, 154g. With this configuration, it is possible to separate the cassette body portion 144 and the cassette bottom portion 142 from each other and remove the side-wall constituent body 110 and the first rotating body 120 to clean up the inside and the bottom portion of the cassette bottom portion 142.

(67) Further, in this embodiment, as shown in FIG. 7 and the like, the bevel gears 152g, 154g respectively coupled with the first driving force transmission axis 152b and the second driving force transmission axis 154b are configured to be located on the lower side of the bevel gears 152f, 154f respectively coupled with the first output axis 152e and the second output axis 154e. Here, it may be possible to take another configuration example in which the bevel gears 152g, 154g are located on the upper side of the bevel gears 152f, 154f so that the bevel gears can be separated from each other, the first output gear 152c and the first input gear 162b cannot be separated from each other and the second output gear 154c and the second input gear 164c cannot be separated from each other. Even in the case of employing such a configuration, the cassette bottom portion 142 and the cassette body portion 144 can be detached from each other by moving the cassette body portion 144 toward the upper side from the cassette bottom portion 142. However, in the case of employing such a configuration, there is a possibility that ridges of teeth of the bevel gears 152f, 152g and the bevel gears 154f, 154g make contact with each other and the engagements among them become difficult at the time of again attaching the cassette body portion 144 to the cassette bottom portion 142.

(68) As shown in FIG. 6 and FIG. 7, an inner-wall 144a having a rectangular frame shape and constituting a part (about half) of an inner peripheral surface along the outer peripheral edge of the second rotating body 130 is formed on the inner periphery side of the cassette body portion 144. A discharging guide piece 180 (see FIG. 12) is attached to one end portion of the inner-wall 144a and this guides the medicines transferred by the second rotating body 130 to the hopper 82a through the medicine discharging part 144c.

(69) As shown in FIG. 6, a guide portion 144b is provided in the cassette body portion 144. The guide portion 144b is used for guiding the medicines when the medicines prepared in the medicine containing part 182 are collected. The guide portion 144b is provided at a position adjacent to the riding-over area Y described later in detail on the outer side of the radial direction of the first rotating body 120 and the second rotating body 130. Further, in the medicine cassette 100, although the support axis for connecting the cover body 102 to the cassette body portion 144 so that the cover body 102 can be pivotally moved with respect to the cassette body portion 144 is provided on one end side of the width direction of the cassette body portion 144, the guide portion 144b is provided on the opposite side with respect to the side on which this support axis is provided (the other end side of the cassette body portion 144). Further, at a position where the guide portion 144b is provided, the cassette body portion 144 is formed into a concave shape and concaved into a spout-like shape. Thus, when the medicines prepared in the medicine containing portion 182 are collected, by opening the cover body 102 and inclining the medicine cassette 100 so that the side on which the guide portion 144b is provided is located on the lower side, the medicines are automatically aggregated in the guide portion 144b and discharged (collected).

(70) Further, as shown in FIG. 6 and FIG. 7, the medicine discharging portion 144c for discharging the medicines is provided on the rear side of the cassette body portion 144. By attaching the medicine cassette 100 to the base portion 60, the medicines can be discharged from the opening constituting the medicine discharging part 144c toward the hopper 82a.

(71) The side-wall constituent body 110 has the upper-end opening portion along the inner peripheral edge of the second rotating body 130 and extends toward the lower side. The lower-end opening portion of the side-wall constituent body 110 is diagonally cut in accordance with an inclination angle of the first rotating body 120. The medicine containing part 182 (see FIG. 9 to FIG. 15B) which can contain the medicines is formed in an area defined by the inner peripheral surface of the side-wall constituent body 110 and the upper surface of the first rotating body 120.

(72) As shown in FIG. 10 and FIG. 12 to FIG. 15B, the side-wall constituent body 110 has an expanding portion 110a expanding toward the outer side of the radial direction of the second rotating body 130 on the lower side of the second rotating body 130. When a position where the outer peripheral edge of the first rotating body 120 and the inner peripheral edge of the second rotating body are adjacent to each other on the upper side of the side-wall constituent body 110 is defined as a reference position (hereinafter, this position is sometimes referred to as “medicine riding-over position X”), the expanding portion 110a is provided on an area (hereinafter, this area is sometimes referred to as “scraping-up side area Z”) on the opposite side of the radial direction of the first rotating body 120 with respect to an area (hereinafter, this area is sometimes referred to as “riding-over side area Y”) on the side on which the medicine riding-over position X exists. In this embodiment, as shown in FIGS. 15(a), 15(b), the expanding portion 110a is provided so as to slightly expand toward the outer side of the radial direction than the outer peripheral edge of the second rotating body 130 on the lower side of the second rotating body 130. If this expanding amount of the expanding portion 110a increases, a size of the medicine cassette 100 becomes large. Thus, it is possible to take a configuration in which the expanding portion 110a does not expand toward the outer side of the radial direction than the outer peripheral edge of the second rotating body 130.

(73) As shown in FIG. 10, FIG. 12 to FIG. 14 and the like, the first rotating body 120 is formed into a circular plate-like shape and has an upper-side portion 120a and a lower-side portion 120b. As shown in FIG. 12 to FIG. 15B and the like, the first rotating body 120 is arranged in the lower-end opening portion of the side-wall constituent body 110 and inclined with respect to the horizontal plane.

(74) As shown in FIG. 16 and the like, a plurality of projections 120c extending from the center side toward the outer diameter side are formed on an upper surface of the upper-side portion 120a. Each projection 120c is inclined toward a direction opposite to the rotational direction of the first rotating body 120 with respect to a line extending from the rotational center of the first rotating body 120 in the radial direction. Further, each projection 120c has a first inclined surface 120x protruding from the upper surface of the upper-side portion 120a and a second inclined surface 120y inclined so as to gradually approach to the upper surface of the upper-side portion 120a as it goes in the rotational direction. An inclination angle of the first inclined surface 120x with respect to the upper surface of the upper-side portion 120a is set to be larger than the second inclined surface 120y. The first inclined surface 120x may be constituted of a plane perpendicular to the upper surface of the upper-side portion 120a. With this configuration, when the first rotating body 120 rotates, the medicines are pushed by the second inclined surface 120y and moved in the rotational direction. Since the medicines are pushed by the second inclined surface 120y, component force in the rotational direction is not so large and the medicines are smoothly transferred in the rotational direction by an appropriate amount. Further, since the projections 120c diagonally extend toward the opposite side with respect to the rotational direction, the medicines are also moved to the outer diameter side and transferred onto the upper surface of the second rotating body 130.

(75) As shown in FIG. 17A and FIG. 17B and the like, the connecting portion 120e (the connecting portion) is provided at the center of the lower-side portion 120b. The connecting portion 120e is formed into a cylindrical shape protruding from the lower-side portion 120b. As shown in FIG. 14 and FIG. 15A, the connecting portion 120e is a portion into which the connecting portion 156g of the driving force transmission portion 156g is inserted. The connecting member 120f formed with a circular plate-like metallic plate made of a magnetic body such as iron or a magnet is attached to the inside of the connecting portion 120e. Thus, by setting the first rotating body 120 so that the connecting portion 156 on the side of the driving force transmission portion 156 is inserted into the connecting portion 120e, it is possible to connect the first rotating body 120 with the driving force transmission portion 156 with magnetic force so that the first rotating body 120 and the driving force transmission portion 156 can integrally rotate.

(76) As described above, the first rotating body 120 is connected to the connecting portion 156g of the driving force transmission portion 156. Here, as shown in FIG. 15B and the like, the connecting axis 156b at which the connecting portion 156g is provided is inclined with respect to the side-wall constituent body 110 and a second rotational axis R2 which is the rotational axis (the axial line) of the side-wall constituent body 110 and the second rotating body 130 by a predetermined angle. Thus, the first rotating body 120 is configured to be capable of rotating around a rotational axis (a first rotational axis R1) inclined with respect to the second rotational axis R2 of the side-wall constituent body 110 and the second rotating body. Further, the first rotating body 120 is arranged in a posture in which the first rotating body 120 is upwardly inclined from the bottom side toward the upper-end side of the side-wall constituent body 110 by a predetermined angle so as to form a raising slope. In a case where the first rotating body 120 is set with a posture in which the rotational axis is vertical, the first rotating body 120 is downwardly inclined from the outer side toward the inner side of the radial direction by a predetermined angle so as to form a falling slope in the outer peripheral portion. Thus, in a state that the first rotating body 120 is arranged in the medicine cassette 100, although the outer peripheral portion of the first rotating body 120 forms the raising slope in the outer peripheral portion as is the case with the inner peripheral portion, a gradient amount in the outer peripheral portion on the side of the riding-over side area Y is smaller than a gradient in the inner peripheral portion.

(77) As shown in FIG. 15B, the first rotating body 120 has a cross-sectional shape curved or bent so that the cross-sectional shape has a concave portion on the upper-side portion 120a on the side of the medicine containing part 182 in an area (hereinafter, this area is sometimes referred to as “main area 120h”) on the inner side of the radial direction than the outer peripheral portion 129i. Thus, compared with a case where the main area 120h has a plate-like shape (see the dotted line in FIG. 15B), the volume of the medicine containing part 182 is larger by an amount obtained by forming the main area 120h into the concave shape. Further, the first rotating body 120 is formed so as to have a cross-sectional shape downwardly inclined from the inner side toward the outer side of the radial direction in the outer peripheral portion 120i. Thus, in the first rotating body 120, a gradient at the position (the medicine riding-over position X) where the outer peripheral portion 120i is adjacent to the inner peripheral edge of the second rotating body 130 and the area (the riding-over side area Y) in the vicinity of the medicine riding-over position X on the upper-end side of the side-wall constituent body 110 becomes more gentle than a gradient in the main area.

(78) Further, in the first rotating body 120, the upper-side portion 120a is formed continuously to an area adjacent to an area (a connecting portion corresponding area 120g) corresponding to the connecting portion 120e. In this embodiment, the connecting portion corresponding area 120g is formed into a shape smoothly continuing to the adjacent area. An expanding amount in the connecting portion corresponding area 120g is set to be substantially equal to the expanding amount of the projection 120c or less than the expanding amount of the projection 120c.

(79) As shown in FIG. 6 and the like, the second rotating body 130 is an annular body arranged on the outer peripheral side of the upper-side opening portion of the side-wall constituent body 110 and having a predetermined width in the radial direction. An annular opening portion 132 protruding toward the upper side is formed on the inner peripheral edge of the second rotating body 130. The annular opening portion 132 is provided so that a lengthwise direction of the medicine positioned on the second rotating body 130 is directed toward the circumferential direction of the second rotating body 130 together with the first guide plane 172 and the second guide plane 174. Namely, the medicines positioned on the second rotating body 130 are transferred with being guided by the first guide plane 172 and the second guide plane 174 and transferred with a posture that the lengthwise direction of each medicine is directed toward the transferring direction. Here, a distance between the discharging guide piece 180 and the second guide plane 174 is set to be slightly larger than a dimension of the medicine in a direction perpendicular to the lengthwise direction of the medicine. By directing the lengthwise direction of the medicine toward the circumferential direction of the second rotating body 130, it is possible to discharge the medicines into the hopper 82a. A height of the annular opening portion 132 is set to be a level enough for smoothly performing the movement of the medicines from the first rotating body 120 and suppressing the medicines from dropping into the inside when the medicines are transferred by the rotation of the second rotating body 130. Further, a second rotating body driven gear 134 is formed on the lower surface of the second rotating body 130 in the circumferential direction. As shown in FIG. 8B, the second rotating body driven gear 134 is partially exposed on the rear side of the cassette main body 140. The second rotating driven gear 134 meshes with the fourth driving gear 70a provided on the side of the base portion 60 when the medicine cassette 100 is attached to the base portion 60. Thus, by driving the fourth motor 70 provided on the side of the base portion 60, it is possible to transmit the driving force through the fourth driving gear 70a and the second rotating body driven gear 134 to rotate the second rotating body 130.

(80) As shown in FIG. 12 to FIG. 14, a step portion 136 is formed on the outer peripheral edge of the second rotating body 130. A rotating guide portion 142j provided on a bottom portion cover body 142b of the cassette bottom portion 142 prevents the step portion 136 from floating up in a state that the second rotating body 130 is assembled with the cassette main body 140. The step portion 136 is positioned on the outer diameter side with respect to the position where the inner-wall 144a is provided in the cassette body portion 144. Thus, in the state that the second rotating body 130 is assembled with the cassette main body 140, the medicines transferred on the upper surface of the second rotating body 130 do not enter into a space between the step portion 136 and the rotating guide portion 142j and the upper surface of the second rotating body 130 is not scratched. Further, the rotating guide portion 142j is arranged on the upper side of the fourth driving gear 70a. With this configuration, it is possible to reliably suppress the floating-up at a portion where force is most strongly applied. Further, after disassembling and cleaning up the medicine cassette 100, it is possible to prevent backlash, positional shift and the like of the parts at the time of the assembling.

(81) The cover body 102 is attached so that the cover body 102 can pivotally move around the support axis provided on one side portion of the cassette body portion 144. As shown in FIG. 2 and FIG. 8A, a cover-side insertion area 102a is formed at a position of the cover body 102 on the front side of the medicine cassette 100. The cover-side insertion area 102a is a concave portion opening toward the top side and the front side of the medicine cassette 100. The fingers can be inserted into the base-side insertion area 102a in the sliding direction (in this embodiment, the direction from the front side toward the rear side) at the time of attaching the medicine cassette 100 with respect to the base portion 60.

(82) The medicine cassette 100 is configured to be appropriately disassembled and cleaned up. Namely, the medicine cassette 100 is configured so that the cassette body portion 144 can be removed from the cassette bottom portion 142 in a state that the height restricting body 160 and the width restricting body 170 are fixed and further the first rotating body 120 and the second rotating body 130 can be removed. As described above, since the medicine cassette 100 is configured so that the parts contacting with the medicines can be disassembled and cleaned up, it is possible to reliably prevent contamination (mixing of different medicines) even in a case where the kind of the medicines is changed or in a case where a part of the medicine is lacked and drops or powder is generated.

(83) The control device 200 drives and controls each motor, the packaging part 40 and the like based on prescription data received from a server (not shown in the drawings) or a detection signal from the discharged medicine detecting device 82b.

(84) Next, description will be given to operations of the medicine packaging apparatus 10 having the above-mentioned configuration. Since the medicine packaging apparatus 10 of this embodiment has features in a dispensing process for the medicines performed by the medicine cassette 100 in the medicine dispensing apparatus 55, the description will be given to only this operation and description for other operations is omitted.

(85) <<Regarding the Dispensing Process for the Medicines>>

(86) In a case of counting medicines whose use frequency is low or the number of the medicines, the medicines can be contained in the medicine cassette 100 provided in the medicine dispensing apparatus 55 and dispensed according to a control flow shown in FIG. 18 to package the medicines. Hereinafter, a medicine dispensing process will be described based on the control flow shown in FIG. 18.

(87) (Step 1-1)

(88) The control device 200 determines whether or not the prescription data to be prescribed by utilizing the medicine dispensing apparatus 55 is received from a host control device for the medicine packaging apparatus 10 or the like. Here, in a case of determining that the prescription data should be prescribed by utilizing the medicine dispensing apparatus 55 (step 1-1=YES), the process is shifted to a step 1-2. Otherwise (step 1-1=NO), the series of control flows are completed.

(89) (Step 1-2)

(90) At the step 1-2, a process for identifying which medicine cassette 100 should be utilized for dispensing the medicines among the plurality of medicine cassettes 100 provided in the medicine dispensing apparatus 55. For example, the control device 200 can perform the process of the step 1-2 with a method of preparing a data table in which information on the medicines prepared in the medicine cassettes 100 is registered in advance and referring to this data table at the step 1-2 to identify which medicine cassette 100 prepares the medicines to be prescribed or the like. In addition, various methods such as a method of identifying the medicine cassette 100 designated by the user as the one to be utilized for dispensing the medicines can be considered as the method for the process at the step 1-2. When the identifying of the medicine cassette 100 to be utilized for dispensing the medicines is completed at the step 1-2, the process is shifted to a step 1-3.

(91) (Step 1-3)

(92) At the step 1-3, the control device 200 performs a process for moving up and down the height restricting body 160 of the medicine cassette 100 identified at the step 1-2 according to the information (a shape, a size and the like) on the medicines to be dispensed. Specifically, by operating the first motor 64, the height restricting body 160 is moved up and down to set the clearance between the lower surface of the height restricting body 160 and the upper surface of the second rotating body 130 to a clearance (height) through which only one medicine can pass. With this configuration, the medicine cassette 100 can dispense the medicines in response to a variety of shapes and sizes of the medicines. Further, unlike the case of distributing the medicines into the manually distributed medicine supplying part 30, it is unnecessary to distribute the medicines for every one package. When the adjustment of the height restricting body 160 is completed, the process is shifted to a step 1-4. In this regard, the information on the shape and the size of the medicines can be obtained by various methods such as a method of referring to a database related to information on predetermined medicines, for example.

(93) (Step 1-4)

(94) At the step 1-4, the control device 200 performs a process for moving up and down the width restricting body 170 of the medicine cassette 100 identified at the step 1-2 according to the information (the shape, the size and the like) on the medicines to be dispensed. Specifically, by operating the second motor 66 to horizontally move the width restricting body 170 for adjusting the positions of the first guide plane 172 and the second guide plane 174 of the width restricting body 170. With this operation, the clearance between the inner peripheral edge of the second rotating body 130 and the first guide plane 172 in the radial direction is set to a dimension through which only one medicine can move. With respect to a width w of the medicine (a dimension in a direction crossing the lengthwise direction), it is preferable to control so that this dimension W1 becomes equal to or larger than ½w and equal to or less than w (½w≤W1≤w). Further, it is preferable to control so that a dimension W2 between the second guide plane 172 and the discharging guide piece 180 becomes equal to or larger than the width w of the medicine and equal to or less than 1.5 times of the width w of the medicine (1.5w) (w≤W2≤1.5w). When the adjustment of the width restricting body 170 is completed, the process is shifted to a step 1-5.

(95) (Step 1-5)

(96) At the step 1-5, the control device 200 performs operation control for the medicine cassette 100 for performing a medicine dispensing preparation operation. As described later in detail, the medicine dispensing preparation operation is performed by rotating the first rotating body 120 and the second rotating body 130 with a high speed according to a control flow shown in FIG. 19. Rotational speeds of the first rotating body 120 and the second rotating body 130 at the time of the medicine dispensing preparation operation are set to be higher than the rotational speeds at the time of the medicine dispensing operation (the step 1-6). By performing the medicine dispensing preparation operation, the medicines prepared in the medicine containing part 182 are quickly transferred and placed onto the second rotating body 130 and reached to the position on the downstream side of the transferring direction of the medicines than the medicine riding-over position X, thereby reducing a time required for dispensing a head (first) medicine. When the medicine dispensing preparation operation is completed, the process is shifted to a step 1-6.

(97) (Step 1-6)

(98) At the step 1-6, the control device 200 performs operation control for the medicine cassette 100 for performing the medicine dispensing process. As described later in detail, the medicine dispensing process is performed by rotating the first rotating body 120 and the second rotating body 130 according to a control flow shown in FIG. 20. The rotational speed of the second rotating body 130 at the time of the medicine dispensing operation is set to be slower than the rotational speed at the time of the above-mentioned medicine dispensing preparation operation. In this regard, the rotational speed of the first rotating body 120 at the time of the medicine dispensing operation may be equal to the rotational speed at the time of the medicine dispensing preparation operation. Further, while the medicine dispensing process is performed for one of the plurality of provided medicine cassettes 100, it may be possible to perform the medicine dispensing preparation operation (the step 1-5) for another medicine cassette 100 for which the medicine dispensing process will be performed in next time. With this configuration, it is possible to quickly discharge the medicines from the medicine cassette 100 for which the medicine dispensing process will be performed in next time after the medicine dispensing process for the medicine cassette 100 from which the dispensing of the medicines should be performed in first is completed. When the medicine dispensing operation is completed, the process is shifted to a step 1-7.

(99) (Step 1-7)

(100) At the step 1-7, the control device 200 performs operation control for the medicine cassette 100 for performing a remaining medicine determining process. The remaining medicine determining process is a process for determining a possibility that the medicines remain in the medicine cassette 100 after the dispensing of the medicines at the step 1-6 is completed. As described later in detail, the remaining medicine determining process is performed according to a control flow shown in FIG. 21. When the remaining medicine determining process is completed, the series of control flows are completed. In this regard, in a case where an error notice (step 1-6-11) along with the dispensing error of the medicines is performed in the medicine dispensing process described later in detail, the remaining medicine determining process according to the step 1-7 may be omitted.

(101) <<Regarding the Medicine Dispensing Preparation Process>>

(102) Subsequently, the medicine dispensing preparation process performed at the above-mentioned step 1-5 will be described according to the control flow shown in FIG. 19.

(103) (Step 1-5-1)

(104) At a step 1-5-1, the control device 200 rotates the first rotating body 120 and the second rotating body 130 in a normal direction. Here, the rotational speeds of the first rotating body 120 and the second rotating body 130 are respectively set to be higher than the rotational speeds of the first rotating body 120 and the second rotating body 130 in the medicine dispensing process performed later. After that, the process is shifted to a step 1-5-2.

(105) (Step 1-5-2)

(106) At the step 1-5-2, the control device 200 determines whether or not the medicines are transferred and placed onto the second rotating body 130. In this embodiment, it is determined that the medicines are transferred and placed onto the second rotating body 130 on a condition that the medicines are detected by the transferred medicine detecting body 145. In a case of determining that the medicines are transferred and placed onto the second rotating body 130 (step 1-5-2=YES), the process is shifted to a step 1-5-3. In a case of not determining that the medicines are transferred and placed onto the second rotating body 130, the process is returned to the step 1-5-1.

(107) (Step 1-5-3)

(108) At the step 1-5-3, the control device 200 determines whether or not a timing (hereinafter, this timing is sometimes referred to as “preparation complete timing”) at which it is expected that the medicine on the head side of the transferring direction of the medicines among the medicines transferred and placed on the second rotating body 130 reaches a predetermined position has come. Specifically, the timing at which it is expected that the medicine reaches a position advanced from the medicine riding-over position X by a predetermined amount (in this embodiment, this amount is 180 degrees) in the circumferential direction is defined as the preparation complete timing and it is determined whether or not this timing has come. Although the determination whether or not the preparation complete timing has come can be performed with various methods, this determination in this embodiment is performed by determining whether or not a timing passing a predetermined time after a timing at which the medicines are detected at the step 1-5-2 has come. In a case of not determining that the preparation complete timing has come (step 1-5-3=NO), the process is returned to the step 1-5-1. In a case of determining that the preparation complete timing has come (step 1-5-3=YES), the series of control flows are completed.

(109) <<Regarding the Medicine Dispensing Process>>

(110) Subsequently, the medicine dispensing process performed at the above-mentioned step 1-6 will be described according to the control flow shown in FIG. 20.

(111) (Step 1-6-1)

(112) At a step 1-6-1, the control device 200 rotates the second rotating body 130. The rotational speed of the second rotating body 130 is set to be slower than the rotational speed of the second rotating body 130 in the medicine dispensing preparation process. In this regard, at the step 1-6-1, the first rotating body 120 may be rotated or brought into a state that the first rotating body 120 is stopped without being rotated. After the start of the rotation of the second rotating body 130, the process is shifted to a step 1-6-2.

(113) (Step 1-6-2)

(114) At the step 1-6-2, the control device 200 determines whether or not the medicines exist on the second rotating body 130. Specifically, it is determined whether or not the medicines are detected by the transferred medicine detecting body 145 arranged on the lateral side of the second rotating body 130. Here, in a case of determining that the medicines exist on the second rotating body 130 (step 1-6-2=YES), the process is shifted to a step 1-6-3. On the other hand, in a case of not determining that the medicines exist on the second rotating body 130 (step 1-6-2=NO), the process is shifted to a step 1-6-4.

(115) (Step 1-6-3)

(116) At the step 1-6-3, the control device 200 performs operation control for bringing the first rotating body 120 into a stand-by state. Namely, in a state that the process is shifted to the step 1-6-3, the medicines exist on the second rotating body 130 and thus it is not necessary to transfer and place the medicines from the first rotating body 120 onto the second rotating body 130 more than necessary. Thus, at the step 1-6-3, the control device 200 performs the control for bringing the first rotating body 120 into the stand-by state. Although the first rotating body 120 may be completely stopped in the stand-by state, the first rotating body 120 may be rotated with a slower speed than the step 1-6-1 or irregularly rotated. In the case of irregularly rotating the first rotating body 120, the rotation and the stop are repeated in sequence or the rotational speed may be continuously or intermittently changed. When the first rotating body 120 is brought into the stand-by state at the step 1-6-3, the process is shifted to a step 1-6-5.

(117) (Step 1-6-4)

(118) At the step 1-6-4, the control device 200 performs control for keeping the rotation of the first rotating body 120. Namely, when the process is shifted to the step 1-6-4, there is a concern that the medicines are not detected by the transferred medicine detecting body 145 at the step 1-6-2 and the medicines are not sufficiently prepared on the second rotating body 130. Thus, at the step 1-6-4, the rotation of the first rotating body 120 is started. After that, the process is returned to the step 1-6-2.

(119) (Step 1-6-5)

(120) At the step 1-6-5, the control device 200 determines whether or not the medicines are dispensed from the medicine cassette 100 based on an output signal from the discharged medicine detecting device 82b. As a result, in a case of detecting that the medicines are discharged within a predetermined time period from the start of the rotation of the second rotating body 130 (step 1-6-5=YES), the process is shifted to a step 1-6-6. On the other hand, in a case of not detecting that the medicines are discharged even after the predetermined time period from the start of the rotation of the second rotating body 130 has passed (step 1-6-5=NO), there is a possibility that the dispensing error occurs because of clogging of the medicines or the like. Thus, in this case, the process is shifted to a step 1-6-8.

(121) (Step 1-6-6)

(122) At the step 1-6-6, the control device 200 performs a process for reversely rotating the second rotating body 130 by a predetermined amount. Although a rotational speed of the second rotating body 130 at the time of the reverse rotation may be equal to that at the time of the normal rotation, the rotational speed of the second rotating body 130 at the time of the reverse rotation is set to be higher than that at the time of the normal rotation. Specifically, at the time of the reverse rotation, the second rotating body 130 is rotated with a rotational speed of about 1.5 to 2 times of the rotational speed at the time of the normal rotation. With this configuration, it is possible to prevent the medicines from being mistakenly dispensed subsequent to the medicines whose dispensing is detected at the step 1-6-5 or a step 1-6-10 and expand the distances between the medicines aligned on the second rotating body 130. When the process at the step 1-6-6 is completed, the process is shifted to a step 1-6-7.

(123) (Step 1-6-7)

(124) At the step 1-6-7, the control device 200 determines whether or not the number of the medicines discharged from the medicine cassette 100 reaches a predetermined number. In this regard, in the medicine dispensing process, in a case where the transferred medicine detecting body 145 does not detect the medicines any more, the medicines may be moved onto the second rotating body 130 by rotating the first rotating body 120 with a high speed. Here, in a case of determining that the dispensing of the medicines by the predetermined number is completed (step 1-6-7=YES), the series of processes are completed. On the other hand, in a case where the number of the dispensed medicines does not reach the predetermined number, the process is returned to the step 1-6-1.

(125) (Step 1-6-8)

(126) In the case where the process is shifted from the step 1-6-5 to the step 1-6-8, there is the concern that the dispensing error such as clogging of the medicines occurs as described above. Thus, at the step 1-6-8, the control device 200 allows the medicine cassette 100 to perform an operation (a dispensing error solving operation) for solving the dispensing error. The dispensing error solving operation may be any operation as long as it can possibly solve a cause of the dispensing error. In this embodiment, control for reversely rotating the second rotating body 130, that is control for rotating the second rotating body 130 by a predetermined amount or for a predetermined time period in a direction in which the medicines are moved toward the opposite side with respect to the discharging port is performed. With this configuration, the posture of the medicines accumulated in the vicinity of the discharging port of the medicine cassette 100 is collapsed and thereby the solving of the dispensing error is expected. When the dispensing error solving operation is performed as described above, the process is shifted to a step 1-6-9.

(127) (Step 1-6-9)

(128) At the step 1-6-9, the control device 200 performs control for rotating the second rotating body 130 in the normal direction. With this control, the dispensing operation for the medicines temporally stopped for the dispensing error solving operation at the step 1-6-8 is restarted. After that, the process is shifted to the step 1-6-10.

(129) (Step 1-6-10)

(130) At the step 1-6-10, the control device 200 determines whether or not the medicines are dispensed from the medicine cassette 100 based on the output signal from the discharged medicine detecting device 82b. As a result, in a case of detecting the discharging of the medicines (step 1-6-10=YES), the process is shifted to the above-mentioned step 1-6-6. In a case of not detecting the discharging of the medicines (step 1-6-10=NO), the process is shifted to a step 1-6-11.

(131) (Step 1-6-11)

(132) In the case where the process is shifted to the step 1-6-11, this case means that the dispensing error of the medicines is not solved even after performing the dispensing error solving operation at the step 1-6-8. Thus, in this case, the control device 200 performs the error notice to inform the user that maintenance is required. After that, the series of processes are completed.

(133) <<Regarding the Remaining Medicine Determining Process>>

(134) Subsequently, the remaining medicine determining process performed at the above-mentioned step 1-7 will be described according to the control flow shown in FIG. 21.

(135) (Step 1-7-1)

(136) At the step 1-7-1, the control device 200 performs a process for starting the reverse rotation of the second rotating body 130. In a case where the medicines exist on the second rotating body 130, the medicines are returned to the upstream side of the dispensing direction. After that, the process is shifted to a step 1-7-2.

(137) (Step 1-7-2)

(138) At the step 1-7-2, the control device 200 determines whether or not the existence of the medicines on the second rotating body 130 is detected. In this embodiment, it is determined whether or not the medicines are detected by the transferred medicine detecting body 145 arranged on the lateral side of the second rotating body 130. Here, in a case of not detecting the medicines (step 1-7-2=NO), the process is shifted to a step 1-7-3. On the other hand, in a case of detecting the medicines (step 1-7-2=YES) the process is shifted to a step 1-7-4.

(139) (Step 1-7-3)

(140) At the step 1-7-3, the control device 200 determines whether or not a time corresponding to a predetermined determination time period has passed from the start of the reverse rotation of the second rotating body 103 at the step 1-7-1. Here, although the determination time period can be appropriately set, it is preferable that the determination time period is set to be equal to or longer than a time period expected to be required for allowing the medicine existing at a position on the most downstream side of the dispensing direction of the medicines (in the vicinity of the discharging port) on the second rotating body 130 to pass through the position where the sensor or the like (in this embodiment, this is the transferred medicine detecting body 145) for determining the presence/absence of the medicines is arranged. In a case of determining that the time corresponding to the determination time period has passes from the start of the reverse rotation of the second rotating body 130 at the step 1-7-3 (step 1-7-3=YES), the process is shifted to a step 1-7-5. On the other hand, in a case of determining that the time corresponding to the determination time period has not passes, the process is returned to the step 1-7-2.

(141) (Step 1-7-4)

(142) In the case where the process is shifted to the step 1-7-4, there is a significantly high possibility that the existence of the medicines is detected by reversely rotating the second rotating body 130 and the medicines remain in the medicine cassette 100. Thus, at the step 1-7-4, the control device 200 performs the determination that there is the high possibility that the medicines remain and performs an alert or the like indicating the high possibility. After that, the control flow is shifted to a step 1-7-5.

(143) (Step 1-7-5)

(144) In the case where the process is shifted to the step 1-7-5, the medicines are not detected even after the second rotating body 130 is reversely rotated for the predetermined determination time period. Thus, it can be considered that the possibility that the medicines remain in the medicine cassette 100 is low. Thus, at the step 1-7-5, the second rotating body 130 is stopped and the series of control flows are completed.

(145) In the above-mentioned medicine cassette 100 of the present invention, the expanding portion 110a is provided on the side-wall constituent body 110. The expanding portion 110a expands toward the outer side of the radial direction on the lower side of the second rotating body 130 and thus it is possible to make the medicine containing part 182 larger by an amount corresponding to the expanding amount of the expanding portion 110a, thereby efficiently utilizing an area on the lower side of the second rotating body 130. Further, in this embodiment, the expanding portion 110a is provided in the scraping-up side area Z positioned on the opposite side of the radial direction of the first rotating body 120 with respect to the riding-over side area X in which the medicine riding-over position X (a rotating body adjacent portion) at which the first rotating body 120 and the second rotating body 130 are adjacent to each other exists. With this configuration, a volume occupied by the side-wall constituent body 110 in the area on the lower side of the riding-over area Y which does not contribute to the increase of the volume of the medicine containing part 182 is suppressed to a minimum. Thus, by providing the expanding portion 110a as described above, it is possible to further contribute to the improvements of the space efficiency in the medicine cassette 100 and the volume of the medicine containing part 182 with making the medicine cassette 100 compact.

(146) In this regard, in this embodiment, although the example in which the expanding portion 110a is provided in the scraping-up side area Z and the expanding portion 110a is not provided on the lower side of the riding-over side area Y is described, the expanding portion 110a may be provided on the lower side of the riding-over area Y.

(147) In the medicine cassette 100 of this embodiment, the transferred medicine detecting body 145 is provided and the medicines can be detected in the transfer path to the medicine discharging part 144c after the medicines are transferred and placed from the first rotating body 120 onto the second rotating body 130. Thus, according to the medicine cassette 100, it is possible to identify the transfer status of the medicines based on the detection signal from the transferred medicine detecting body 145 and utilize it for the operation control for the medicine cassette 100. Specifically, as described above, it is possible to utilize the detection information from the transferred medicine detecting body 145 for optimizing the rotational speed of the first rotating body 120 depending on whether or not the medicines exist on the second rotating body 130. Further, it is possible to utilize the detection information from the transferred medicine detecting body 145 for the application of determining the presence/absence of the discharging error in the medicine discharging part 144c and the application of determining the remaining status of the medicines after the completion of the dispensing of the medicines. In this regard, although the example in which the transferred medicine detecting body 145 is provided is described in this embodiment, the present invention is not limited thereto and it may be possible to take a configuration in which the transferred medicine detecting body 145 is not provided. Further, although the example in which the transferred medicine detecting body 145 is utilized for some applications such as the rotation control for the first rotating body 120, the detection of the discharging error of the medicines and the detection of the remaining status of the medicines, different detecting bodies such as sensors may be provided for each application.

(148) In the medicine cassette 100 of this embodiment, the first rotating body 120 is formed into the concave shape on the side of the medicine containing part 182. With this configuration, compared with the case where the first rotating body 120 is formed into the shape such as a plate-like shape, it is possible to improve the volume of the medicine containing part 182 and make the medicine cassette 100 compact. Further, the first rotating body 120 is formed so as to be downwardly inclined from the inner side toward the outer side of the radial direction at the outer peripheral portion 120i. Thus, the gradient of the first rotating body 120 becomes gentle in the vicinity of the medicine riding-over position X. With this configuration, it is possible to smoothly transfer and place the medicines from the first rotating body 120 onto the second rotating body 130. Further, by forming the outer peripheral portion 120i of the first rotating body 120 into the shape downwardly inclined from the inner side toward the outer side of the radial direction, it is possible to set the arrangement angle (the gradient) as the whole of the first rotating body 120 to be higher. With this configuration, it is possible to suppress a square measure required for arranging the first rotating body 120 to a minimum, thereby suppressing the width and the length of the medicine cassette 100 and making the medicine cassette 100 compact.

(149) In this regard, although the example in which the first rotating body 120 is formed into the concave portion on the side of the medicine containing part 182 is described in this embodiment, the present invention is not limited thereto and the first rotating body 120 may not be formed into the concave portion. Further, although the example in which the first rotating body 120 is formed so as to be downwardly inclined from the inner side toward the outer side of the radial direction at the outer peripheral portion 120i is described in this embodiment, the present invention is not limited thereto and it may be possible to take a configuration in which the first rotating body 120 is not inclined at the outer peripheral portion 120i.

(150) In this embodiment, the connecting portion 120e for connecting the first rotating body 120 to the side of the driving force source is provided on the outer side of the medicine containing part 182. Further, the surface of the first rotating body 120 on the side of the medicine containing part 182 is formed continuously to the area adjacent to the area corresponding to the connecting portion 120e and does not have a discontinuously protruding portion. Thus, it is possible to suppress a decrease of the volume of the medicine containing part 182 caused by the connecting portion 120e to a minimum. Further, in the case of inclining the medicine cassette 100 for collecting the medicines, there is no portion contacting with the medicines and thus problems such as bouncing of the medicines do not occur. In this regard, although the example in which the discontinuous portion such as a protrusion protruding toward the side of the medicine containing part 182 caused by the connecting portion 120e is not formed is described in this embodiment, the present invention is not limited thereto and the discontinuous portion may be formed.

(151) Further, according to the medicine cassette 100 of this embodiment, by inclining the cassette main body 140 in the state that the cover body 102 is opened, it is possible to collect the medicines remaining in the medicine containing part 182. Further, in the medicine cassette 100, the rotating guide portion 142j for guiding the medicines to be collected is provided at the position opposite to the support axis of the cover body 102 in the cassette 140. Thus, according to the medicine cassette 100, it is possible to easily and smoothly perform the collecting operation for the medicines in the medicine containing part 182. In this regard, the example in which the guide portion 144b is provided is described in this embodiment, the present invention is not limited thereto and the guide portion 144b may not be provided. Further, the shape and the position of the guide portion 144b is not limited to the above-described one and it is possible to appropriately change the shape and the position to an efficient shape and position for collecting the medicines.

(152) The medicine cassette 100 of this embodiment includes the cassette connecting mechanism 73. The cassette connecting mechanism 73 can allow the two engaging pieces 78d, 78d provided on the side of the base portion 60 with being spaced apart from each other to respectively engage with the two receiving portions 142x, 142x provided on the side of the medicine cassette 100 (the cassette main body 140) to fix the medicine cassette 100 with respect to the base portion 60 with a correct posture without inclining with respect to the base portion 60. In this regard, although the example in which the engaging pieces 78d, 78d are provided on the side of the base portion 60 and the receiving portions 142x, 142x are provided on the side of the medicine cassette 100 is described in this embodiment, it may be possible to take an appropriate configuration in which the engaging pieces 78d, 78d are provided on the side of the medicine cassette 100 and the receiving portions 142x, 142x are provided on the base portion 60, for example. Further, the medicine cassette 100 may not include the cassette connecting mechanism 73.

(153) In the above-mentioned medicine dispensing apparatus 55, the cover-side insertion area 102a is provided in the cover body 102 of the medicine cassette 100 and the base-side insertion area 80d is provided in the base portion 60. Thus, even if a plurality of medicine dispensing apparatuses 55 are arranged in the vertical direction so as not to be spaced apart from each other, it is possible to perform the attaching and detaching operation for the medicine cassette 100 with respect to the base portion 60 by inserting the fingers into the cover-side insertion area 102a and the base-side insertion area 80d to clip the front side of the medicine cassette 100. Thus, with the above-mentioned configuration, it is possible to easily and reliably perform the attaching and detaching operation for the medicine cassette 100. In this regard, although the example in which the cover-side insertion area 102a and the base-side insertion area 80d are provided is described in this embodiment, the present invention is not limited thereto and it may be possible to take a configuration in which one or both of the cover-side insertion area 102a and the base-side insertion area 80d are not provided.

(154) Further, although the cover-side insertion area 102a and the base-side insertion area 80d are formed with the cutouts formed by concaving a part of the front side of the medicine dispensing apparatus 55 toward the rear side in this embodiment, the present invention is not limited thereto. Specifically, each of the cover-side insertion area 102a and the base-side insertion area 80d may be formed into a shape obtained by cutting an overall width of the front side area of the medicine dispensing apparatus 55 toward the rear side as is the case with the cover-side insertion area 102a shown in FIG. 25A. Further, as shown in FIG. 25B, the cover-side insertion area 102a may be formed into a shape obtained by removing the portion indicated by the dotted line in FIG. 25B and cutting the overall width of the front side area of the medicine dispensing apparatus 55 toward the rear side. Namely, one or both of the cover body 102 and the bottom-side portion 80 of the base portion 60 may be formed into a shape which is not flat with respect to the anterior surface (the front surface) of the cassette main body 140 and positioned on the rear side of the anterior surface (the front surface). Further, although the example in which the base-side insertion area 80d is formed by providing the cutout or the concave portion communicated from the upper surface side to the lower surface side of the base portion 60 is described in this embodiment, the present invention is not limited thereto. Specifically, as shown in FIG. 25C, the base-side insertion area 80d may be formed by a concave or a cutout provided in only the upper surface side of the base portion 60.

(155) As described above, the control device 200 performs the rotation control for reversely rotating the second rotating body 130 by the predetermined amount every time when the dispensing of the medicines is detected along with the normal rotation of the second rotating body 130 in the medicine dispensing process. By performing such rotation control, the clearances between the medicines on the second rotating body 130 are expanded. With this configuration, it is possible to suppress another medicine subsequent to the medicine to be dispensed from being mistakenly dispensed. In this regard, although the example in which the control device 200 constitutes the discharging status determining apparatus and the cassette control device of the present invention is described in this embodiment, the present invention is not limited thereto. Namely, one or both of the discharging status determining device and the cassette control device may be constituted of another device than the control device 200. Further, although the example in which the second rotating body 130 is reversely rotated every time when one medicine is dispensed is described in this embodiment, the present invention is not limited thereto. Specifically, it may be possible to take a configuration in which the control for reversely rotating the second rotating body 130 is not performed after the dispensing of the medicines is detected or the second rotating body 130 is reversely rotated regularly or at an irregular predetermined timing.

(156) In this embodiment, the medicine dispensing preparation process (the step 1-5) is performed prior to the medicine dispensing process (the step 1-6) in the packaging process. In the time period when the medicine dispensing preparation process is performed, that is the time period from the timing at which it is expected that the medicines are transferred and placed from the medicine containing part 182 onto the second rotating body 130 along with the rotation of the first rotating body 120 to the timing at which it is expected that the medicine located at the head position of the transferring direction among the medicines transferred and placed onto the second rotating body 130 and transferred toward the side of the medicine discharging part 144c reaches the predetermined position, the rotational speed of the second rotating body 130 is set to be higher than that at the time of the medicine dispensing process. With this configuration, it is possible to suppress the time required for enabling the medicines transferred and placed onto the second rotating body 130 to reach in the vicinity of the medicine discharging part 144c to a minimum and smoothly start the dispensing of the medicines.

(157) In this regard, although the example in which the medicine dispensing preparation process is performed in order to reduce the required time until the head (first) medicine is dispensed is described in this embodiment, the present invention is not limited thereto and it may be possible to take a configuration in which the medicine dispensing preparation process is not performed. Further, although the example in which the first rotating body 120 is also rotated with the higher speed than that at the time of the medicine dispensing process in addition to the second rotating body 130 in the medicine dispensing preparation process is described, the present invention is not limited thereto. Specifically, it may be possible to take a configuration in which the first rotating body 120 is rotated with the same speed as that at the time of the medicine dispensing process or the rotational speed of the first rotating body 120 becomes slow at the time of detecting the transferring and placing of the medicines onto the second rotating body 130 (step 1-5-2=YES). Although the example in which the control device 200 constitutes the cassette control device of the present invention and performs the control related to the medicine preparing process, the present invention is not limited thereto and it may be possible to take a configuration in which another device corresponding to the cassette control device for performing the control related to the medicine preparing process is provided.

(158) In this embodiment, the determination that the dispensing error of the medicines occurs is performed by the control device 200 in the medicine dispensing process on the condition that the discharging of the medicines is not detected by the discharged medicine detecting device 82b even after the second rotating body 130 is rotated over the predetermined time and the medicines are detected by the transferred medicine detecting body 145. With this configuration, it is possible to accurately determine whether or not the dispensing error of the medicines occurs. Further, the operation (the dispensing error solving operation) for rotating the second rotating body 130 in the direction opposite to the discharging direction of the medicines is performed on the condition that the determination that the dispensing error of the medicines occurs is performed by the control device 200. With this configuration, it is possible to solve the dispensing error without troubling the hands of the user.

(159) In this regard, although the example in which the determination control for the discharging error of the medicines or the performing control for the discharging error solving operation is performed is described in this embodiment, the present invention is not limited thereto and it may be possible to take a configuration in which one or both of these controls are not performed. Further, although the example in which the control device 200 constitutes the discharging status determining device and the cassette control device of the present invention is described in this embodiment, the present invention is not limited thereto and another device corresponding to the discharging status determining device or the cassette control device may be provided.

(160) In this embodiment, the remaining medicine determining process (the step 1-7) is performed after the medicines are dispensed in the medicine dispensing process (the step 1-6). Further, in the remaining medicine determining process, the determination that there is the possibility that the medicines remain in the medicine cassette 100 is performed on the condition that the second rotating body 130 is rotated in the direction opposite to the discharging direction of the medicines and the medicines are detected by the transferred medicine detecting body 145 after the start of the reverse rotation. By performing the remaining medicine determining process as described above, it is possible to identify the possibility that the medicines remain in the medicine cassette 100 and inform this possibility to the user. In this regard, although the example in which the remaining medicine determining process is performed is described in this embodiment, the remaining medicine determining process is not an essential process in the present invention and it is possible to appropriately omit the remaining medicine determining process. Further, although the example in which the control device 200 constitutes the remaining medicine determining device of the present invention, the present invention is not limited thereto and another device corresponding to the remaining medicine determining device may be provided.

(161) Further, in this embodiment, the first rotating body 120 is rotated with the slower speed than that at the time of the transferring and placing operation, stopped or irregularly rotated on the condition that the medicines are detected by the transferred medicine detecting body 145. Specifically, in the case of detecting that the medicines exist on the second rotating body 130 in the medicine dispensing process (step 1-6-2=YES), the first rotating body 120 is brought into the stand-by state (the step 1-6-3) and the first rotating body 120 is rotated with the slower speed than that at the time of the transferring and placing operation, stopped or irregularly rotated. With this configuration, it is possible to collapse the posture of the medicines in the medicine containing part 182 and suppress the medicines in the medicine containing part 182 from being mistakenly detected as being existing on the second rotating body 130. Further, by rotating the first rotating body 120 with the slower speed than that in the transferring and placing operation, stopping or irregularly rotating the first rotating body 120, it is possible to suppress load applied to the medicines in the medicine containing part 182 to a minimum and suppress breakage or abrasion of the medicines.

(162) In this regard, although the first rotating body 120 is rotated with the slower speed, stopped or irregularly rotated at the time of bringing the first rotating body 120 into the stand-by state in this embodiment in order to suppress the medicines from being detected as being existing on the second rotating body 130 by the transferred medicine detecting body 145, the present invention is not limited thereto and it may be possible to take a configuration in which the first rotating body 120 is not brought into the stand-by state. Further, although the example in which the control device 200 is used for controlling the first rotating body 120 so as to bring the first rotating body 120 into the stand-by state is described in this embodiment, it may be possible to employ another device than the control device 200 as a control device (equivalent to the cassette control device of the present invention) performing such control.

(163) Further, according to the medicine packaging apparatus 10, the medicine dispensing apparatus 55 and the medicine cassette 100 described above, it is possible to suppress the occurrence of the human errors caused by the manual operations and smoothly dispense the medicines with a minimum space to package the medicines.

(164) The present invention is not limited to the configuration described in the above embodiment and various modifications can be applied to the present invention.

(165) For example, although the case where the medicines whose use frequency is low are packaged by utilizing the medicine dispensing apparatus 55 is described in the above-mentioned embodiment, this medicine dispensing apparatus 55 can be utilized for a case of counting the number of the medicines. In this case, another route than the discharging route to the side of the packaging part for guiding the medicines discharged from the hopper 82a to the front side of the attached medicine cassette 100 as is the above-mentioned case is formed and the medicines discharged from this other route are collected with a vial bottle or the like. Further, in a case of dispensing the medicines into the vial bottle by a predetermined amount, the method can be also used.

(166) Further, it is possible to employ the medicine cassette 100 used in the medicine dispensing apparatus 55 as the medicine cassette 22 of the first medicine supplying part 20 or employ the medicine dispensing apparatus 55 or the medicine cassette 100 in the manually distributed medicine supplying part 30. In a case of employing the medicine cassette 100 or the medicine dispensing apparatus 55 as the medicine cassette 22 or in the manually distributed medicine supplying part 30, it is also possible to appropriately omit a part of the configuration and simplify the configuration.

(167) In the above-mentioned medicine packaging apparatus 10, the display panel 146 (the display device) is provided in the medicine dispensing apparatus 55. Although the control for allowing the display device 146 to display the information such as medicine information can be appropriately performed by the control device 200 and the like, it is preferable that the control is performed so as to reliably allow the display panel 146 to display the necessary information or sufficiently protect the display panel 146. Specifically, if the medicine cassette 100 is removed during the rewriting time from the start to the end of the transmitting of the display data for the information displaying to the display panel 146 or the like and the power supply to the display panel 146 is interrupted, the necessary information cannot be displayed on the display panel 146 and this may cause failure of the display panel 146. Thus, it is preferable that the operation control for each part is performed so that the power supply to the display panel 146 is not interrupted during the rewriting time. Further, with considering the phenomenon found by the inventors that the rewriting time varies depending on the temperature condition (the environment temperature condition) of the location where the medicine dispensing apparatus 55 is set, it is preferable that the rewriting time is set based on the environment temperature condition and the control is performed so that the connection between the display panel 146 and the power supplying part 72 which is the power supply source is not released during this rewriting time.

(168) Based on the above-mentioned knowledge, the medicine packaging apparatus 10 or the medicine dispensing apparatus 55 may include a configuration shown in the block diagram in FIG. 22, for example. Specifically, in the example shown in FIG. 22, a temperature detecting part 202 is provided and the control device 200 includes a display control part 204 (a display control device) and a connection control part 206 (a connection control device). Hereinafter, this is described in detail based on FIG. 22 and the like.

(169) The temperature detecting part 202 can detect a temperature of a setting environment (a setting environment temperature t). For example, the temperature detecting part 202 is constituted of a temperature sensor and is configured to detect the setting environment temperature t for every medicine cassette 100. Although the temperature detecting part 202 may be set at any location, the temperature detecting part 202 is arranged in each medicine cassette 100 so as to be positioned in the vicinity of an electronic substrate having a function of the display control part 204 described later in detail in this embodiment.

(170) The display control part 204 can create the display data used for allowing the display panel 146 to display the information and transmit the display data to the display panel 146.

(171) The display control part 206 is used for controlling so as to keep a connection between the power supplying part 72 which is an electric power supply source (a power supplying part) for the display panel 146 and the display panel 146. In this embodiment, when the medicine cassette 100 is attached to the base portion 60, the power supplying part 72 and the display panel 16 are brought in a state that they are electrically connected with each other. Further, in this embodiment, a cassette connecting mechanism 73 (a connection keeping part) is provided as a mechanism for keeping the connection of the medicine cassette 100 attached to the base portion 60. Thus, the connection control part 206 can perform operation control for the cassette connecting mechanism 73 to perform control for keeping the connection between the power supplying part 72 and the display panel 146.

(172) Further, the connection control part 206 can set the rewriting time L based on the setting environment temperature t detected by the temperature detecting part 202. The rewriting time L can be set with various methods such as a method of setting the rewriting time L based on a pre-defined arithmetic equation and a method of setting the rewriting time L in a phased manner depending on whether the setting environment temperature t is higher or lower than a predetermined threshold temperature ts used as a reference. In this embodiment, the latter setting method is employed and the rewriting time L in a case where the environment temperature t is higher than the predetermined threshold temperature ts (for example, 3 seconds) is set to be shorter than the rewriting time L in a case where the environment temperature t is lower than the predetermined threshold temperature ts (for example, 15 seconds) as shown in FIG. 24A. With this configuration, the rewriting time L can be switched in a two-phase manner based on the setting environment temperature t.

(173) A process (a display changing process) related to display change for the display panel 146 performed in the case of employing the configuration shown in the above-mentioned block diagram in FIG. 22 will be described according to the flow chart shown in FIG. 23.

(174) (Step 2-1)

(175) At a step 2-1, the control device 200 determines whether or not the display change for the display panel 146 is necessary. Here, in a case where the display change is necessary (step 2-1=YES), the process is shifted to a step 2-2. In a case where the display change is not necessary (step 2-1=NO), the determination whether or not the display change is necessary is continued.

(176) (Step 2-2)

(177) At the step 2-2, a process of setting the rewriting time L based on the setting environment temperature t detected by the temperature detecting part 202 is performed by the connection control part 206. In this embodiment, the rewriting time L is set according to the determination whether or not the setting environment temperature t detected by the temperature detecting part 202 is on the higher side with respect to the threshold temperature is used as the reference. After that, the process is shifted to a step 2-3.

(178) (Step 2-3)

(179) At the step 2-3, the operation control for the cassette connecting mechanism 73 is performed by the connection control part 206 so that a state (a locked state) that the medicine cassette 100 is connected to the base portion 60 is kept and the power supply from the power supplying part 72 is not physically interrupted. After that, the process is shifted to a step 2-4.

(180) (Step 2-4)

(181) At the step 2-4, the display data used for allowing the display panel 146 to display the information is created by the display control part 204 and transmitted to the side of the display panel 146. After that, the process is shifted to a step 2-5.

(182) (Step 2-5)

(183) At the step 2-5, the determination whether or not the time period corresponding to the rewriting time L has passed from the start time of the transmitting of the display data is performed by the connection control part 206. In a case of determining that the time period corresponding to the rewriting time L has not passed (step 2-5=NO), the process stands by at the step 2-5. In a case of determining that the time period corresponding to the rewriting time L has passed (step 2-5=YES), the process is shifted to a step 2-6.

(184) (Step 2-6)

(185) At the step 2-6, operation control for the cassette connecting mechanism 73 is performed by the connection control part 206 so as to take a state (a lock released state) that the lock of the medicine cassette 100 with respect to the base portion 60 is released. With this control, the series of control flows are completed.

(186) As described above, by preventing the medicine cassette 100 from being removed during the rewriting time from the start to the end of transmitting the display data for the display change to the display panel 146, it is possible to reliably allow the display panel 146 to display the necessary information and prevent errors such as failure of the display panel 146 caused by unexpected power supply interruption. Further, by changing the rewriting time L depending on the environment temperature condition, it is possible to further improve the reliability of the information displaying to the display panel 146 and significantly reduce the errors such as the failure of the display panel 146.

(187) In this regard, the configuration or the control method for preventing the medicine cassette 100 from being removed during the time period from the start to the end of transmitting the display data for the information displaying to the display panel 146 are not limited to the above-described ones and can be appropriately modified. Further, such configuration and control are not essential for the medicine packaging apparatus 10 and the medicine dispensing apparatus 55 and can be also appropriately omitted.

(188) Further, although the example in which the rewriting time L is changed depending on the environment temperature condition is described in the above-mentioned example, the present invention is not limited thereto and the rewriting time L may be constant regardless of the environment temperature condition. In this case, it is preferable that the rewriting time L is set to be long in order to suppress the power supply to the display panel 146 from being interrupted while the displaying of the display panel 146 is being changed. Further, although the example in which only the environment temperature condition is employed as a changing factor for the rewriting time L is described in the above-mentioned example, another condition may be considered for optimizing the rewriting time L.

(189) Further, although the configuration in which the power supply to the display panel 146 is stopped immediately after the connection to the power supplying part 72 is released is described in this embodiment, the present invention is not limited thereto. Specifically, it may be possible to take a configuration in which a supplementary power supplying device such as a capacitor and a condenser may be provided in the medicine cassette 100 to supply the electric power to the display panel 146 during a predetermined supplementary power supply time Lh which is shorter than the rewriting time when the connection to the power supplying part 72 is released. In this case, as shown in FIG. 24B, even if the time period from the timing at which the process for rewriting the displaying of the display panel 146 is started to the timing at which the lock released state can be taken is shortened by the amount corresponding to the supplementary power supply time Lh, errors such as an error of the display change of the display panel 146 do not occur.

(190) Up to here, although the representative embodiments of the present invention are described, it should be noted that various design changes can be performed within the scope of the technical idea of the present invention described in the claims and all of such modifications are also involved in the present invention.

(191) The present invention can be preferably used in general medicine packaging apparatuses for packaging medicines, general medicine dispensing apparatuses for dispensing medicines and general medicine cassettes.
