When the optical sensor 6 reads information from the card 2, the read information is transmitted to the host apparatus.

[0045] As shown in FIG. 6 and FIG. 7, the optical sensor 6 is turned by the turning mechanism 7 between a first position 6A where the reading face 60 is directed to the Z2 direction side and a second position 6B where the reading face 60 is directed to the Z1 direction side.

(Turning Mechanism)

[0047] FIG. 8 is an exploded perspective view showing the optical sensor 6 and a holder 71. As shown in FIG. 6 and FIG. 7, the turning mechanism 7 is fixed to the support member 15. The turning mechanism 7 includes the holder 71 which holds the optical sensor 6 and a drive part 72 which turns the holder 71 between the first position 6A and the second position 6B with the turning axis L as a center. As shown in FIGS. 6, FIG. 7 and FIG. 8, the holder 71 is provided with a first plate part 73, a second plate part 74 which is bent in a radial direction from an end part on the X1 direction side of the first plate part 73, a third plate part 75 which is bent in the radial direction from an end part on the X2 direction side of the first plate part 73, and a fourth plate part 76 which faces the first plate part 73. As shown in FIGS. 6 and FIG. 7, the holder 71 is capable of turning with the turning axis L as a center in a state that the second plate part 74 is supported by the third wall part 18 through a shaft member 13 and the third plate part 75 is connected with a shaft part of an output gear 782 by a screw.

[0048] Each of the second plate part 74 and the third plate part 75 is provided with a protruded part 70 which is protruded to an outer side in the radial direction with respect to the fourth plate part 76. The optical sensor 6 is fixed to the first plate part 73 by a screw. As shown in FIG. 7 and FIG. 8, the fourth plate part 76 is provided with a protruded part 761 which is protruded to an outer side in the radial direction, and a bent part 762 which is bent in a circumferential direction from a tip end portion of the protruded part 761. The protruded part 761 is protruded to an opposite side to a side to which the reading face 60 of the optical sensor 6 is directed. The flexible wiring board 61 is fixed to the protruded part 761 by a fixing member 760. In this embodiment, the fixing member 760 is a binding band. In accordance with an embodiment of the present invention, the fixing member 760 is not limited to a binding band. The fixing member 760 may be, for example, a double sided tape or an adhesive. Further, as shown in FIG. 7, when the holder 71 is turned from the first position 6A to the second position 6B, the flexible wiring board 61 is bent along the bent part 762.

[0049] As shown in FIG. 6 and FIG. 7, the drive part 72 includes a motor 77 and a gear train 78 for transmitting a drive force of the motor 77 to the holder 71. The motor 77 is a DC motor and includes an encoder 79. The motor 77 is fixed to the fourth wall part 19 by a screw. The gear train 78 includes a pinion 781 fixed to an output shaft of the motor 77 and an output gear 782 which is engaged with the pinion 781. The X1 direction side of the shaft part of the output gear 782 is connected with the holder 71 by a screw. The X2 direction side of the shaft part of the output gear 782 is turnably supported by the fourth wall part 19.

[0050] In this embodiment, the support member 15 is provided with a position detection sensor 11 which detects that the optical sensor 6 is located at the first position 6A and the second position 6B. In this embodiment, the position detection sensor 11 is a transmission type photosensor. The position detection sensor 11 is electrically connected with the board 80 through a flexible wiring board or the like. The position detection sensor 11 includes a position detection sensor 11A provided on a face on the Y2 direction side of the first wall part 16, and a position detection sensor 11B provided on a face on the Y1 direction side of the second wall part 17. When the protruded part 70 of the third plate part 75 blocks light of the position detection sensor 11A at the first position 6A, the position detection sensor 11A detects that the optical sensor 6 is located at the first position 6A. When the protruded part 70 of the third plate part 75 blocks light of the position detection sensor 11B at the second position 6B, the position detection sensor 11B detects that the optical sensor 6 is located at the second position 6B.

[0051] The control part 8 drives the turning mechanism 7 based on a detection result of the position detection sensor 11. In other words, in a case that the holder 71 is to be turned from the first position 6A to the second position 6B, the control part 8 drives the turning mechanism 7 until the position detection sensor 11B detects the holder 71. Further, in a case that the holder 71 is to be turned from the second position 6B to the first position 6A, the control part 8 drives the turning mechanism 7 until the position detection sensor 11A detects the holder 71.

[0052] Further, the support member 15 is provided with a restriction member 14. The restriction member 14 is located on the Z2 direction side with respect to the holder 71 and is fixed to a face on the X2 direction side of the third wall part 18. When the restriction member 14 is abutted with the protruded part 70 of the second plate part 74, a turning range of the holder 71 is restricted.

(Operation of Card Issuing Device)

[0053] Next, an operation of the card issuing device 1 will be described below. FIG. 9 is a flow chart showing a card issuing operation which issues a card 2. When a card 2 is to be issued, a card issuing instruction is transmitted to the card issuing device 1 from the host apparatus. The card issuing instruction is inputted into the control part 8.

[0054] As shown in FIG. 9, the control part 8 acquires information from the position detection sensor 11A whether the holder 71 is located at the first position 6A or not (operation ST1). In a case that the holder 71 is not located at the first position 6A (operation ST1: No), the control part 8 drives the turning mechanism 7 to move the holder 71 to the first position 6A until the position detection sensor 11A detects the holder 71 (operation ST2). After that, the procedure is returned to the operation ST1.

[0055] In a case that the holder 71 is located at the first position 6A (operation ST1: Yes), the control part 8 drives the card send-out mechanism 4 to send out a card 2 from the card stack part 31 to the card conveyance mechanism 5 (operation ST3).

[0056] When the card 2 is sent out to the card conveyance mechanism 5, the control part 8 drives the card conveyance mechanism 5 to convey the card 2 to the reading position R (operation ST4). Next, the control part 8 drives the optical sensor 6 to perform a reading operation in which a code 2b of the card 2 is read (operation ST5).

[0057] In this embodiment, in a case that information having been read by the optical sensor 6 is transmitted to the host apparatus, the control part 8 determines that reading of information from the card 2 has been normally performed (operation ST6: Yes). Next, the control part 8 drives the card conveyance mechanism 5 to convey the card 2 toward the card discharge port 10 (operation ST7). As a result, issue of the card 2 is completed.

[0058] In a case that the information having been read by the optical sensor 6 is not transmitted to the host apparatus, the control part 8 determines that reading of information from the card 2 has failed (operation ST6: No). In this case, it is conceivable that an irradiation angle of an illumination light of the optical sensor 6 which is irradiated toward the card 2 is not appropriate and thus, the optical sensor 6 is unable to read the code 2b. Therefore, the control part 8 drives the turning mechanism 7 to turn the holder 71 by several degrees (for example, about 1?) based on positional information of the encoder 79 (operation ST8). As a result, the first position 6A of the optical sensor 6 is finely adjusted and an irradiation angle of the illumination light is also finely adjusted.

[0059] Next, the control part 8 drives the optical sensor 6 to perform reading operation which reads the code 2b of the card 2 again (operation ST9). In a case that information having been read by the optical sensor 6 is transmitted to the host apparatus, the control part 8 determines that reading of information from the card 2 has been normally performed (operation ST10: Yes). Next, the control part 8 drives the card conveyance mechanism 5 to convey the card 2 toward the card discharge port 10 (operation ST7). As a result, issue of the card 2 is completed.

[0060] In a case that the information having been read by the optical sensor 6 is not transmitted to the host apparatus, the control part 8 determines that reading of information from the card 2 has failed (operation ST10: No). In this case, the control part 8 drives the card conveyance mechanism 5 to convey the card 2 toward the collection part 30 (operation ST11). As a result, collection of the card 2 is completed.

[0061] In this embodiment, when the optical sensor 6 is not used, in order to prevent dust from adhering to the reading face 60 of the optical sensor 6, the turning mechanism 7 turns the optical sensor 6 to the second position 6B. Specifically, when a main power supply of the card issuing device 1 is turned off, the control part 8 drives the turning mechanism 7 to turn the optical sensor 6 to the second position 6B. Further, even in a case that a main power supply of the card issuing device 1 is not turned off, it may be structured that, each time issue of a card 2 is completed, the control part 8 drives the turning mechanism 7 to turn the optical sensor 6 to the second position 6B. In addition, even in a case that a main power supply of the card issuing device 1 is not turned off, when issue of a card 2 is not performed for a predetermined time period, it may be structured that the control part 8 drives the turning mechanism 7 to turn the optical sensor 6 to the second position 6B. According to these structures, when the optical sensor 6 is not used, the reading face 60 of the optical sensor 6 is directed to the Z1 direction side and thus, dust can be prevented from adhering to the reading face 60 of the optical sensor 6.

Operations and Effects

[0062] In the card issuing device 1 in this embodiment, the optical sensor 6 is located on the Z1 direction side with respect to the card conveyance passage 50. Therefore, the optical sensor 6 is capable of reading a card 2 in which a code 2b is indicated on its rear face 2a. Further, the dust adhesion prevention mechanism 9 is a turning mechanism 7 structured to turn the optical sensor 6 between the first position 6A where the reading face 60 of the optical sensor 6 is directed to the Z2 direction side and the second position 6B where the reading face 60 is directed to the Z1 direction side. The turning mechanism 7 is capable of setting the reading face 60 of the optical sensor 6 to the first position 6A where the reading face 60 is directed upward when the optical sensor 6 is used and, when the optical sensor 6 is not used, the turning mechanism 7 is capable of setting the reading face 60 of the optical sensor 6 to the second position 6B where the reading face 60 is directed downward. Therefore, when the optical sensor 6 is not used, the reading face 60 of the optical sensor 6 is directed downward and thus, dust can be restrained from adhering to the reading face 60 of the optical sensor 6. As a result, optical performance of the optical sensor 6 can be restrained from being lowered due to dust. Further, the turning mechanism 7 turns the optical sensor 6 from the first position 6A to the second position 6B and thus, dust adhered to the reading face 60 of the optical sensor 6 when the optical sensor 6 is used can be dropped downward.

[0063] In this embodiment, the turning mechanism 7 includes the holder 71 which holds the optical sensor 6 and the drive part 72 which turns the holder 71 between the first position 6A and the second position 6B with the turning axis L as a center. The holder 71 is provided with the protruded part 761 which is protruded to an outer side in the radial direction with respect to the turning axis L. The optical sensor 6 includes the flexible wiring board 61 which is extended to an outer side in the radial direction. The flexible wiring board 61 is fixed to the protruded part 761. Therefore, the flexible wiring board 61 is fixed to the protruded part 761 and thus, when the holder 71 is turned, a force applied to the flexible wiring board 61 can be restrained from applying to a root of the flexible wiring board 61. As a result, the flexible wiring board 61 can be restrained from disengaging from the optical sensor 6.

[0064] In this embodiment, the holder 71 is provided with the bent part 762 which is bent from a tip end portion of the protruded part 761 in a circumferential direction with respect to the turning axis L. When the holder 71 is turned from the first position 6A to the second position 6B, the flexible wiring board 61 is bent along the bent part 762. Therefore, when the turning mechanism 7 turns the holder 71, the bent part 762 functions as a guide for bending the flexible wiring board 61 and thus, the flexible wiring board 61 is easily bent.

[0065] In this embodiment, the card issuing device 1 includes the position detection sensor 11 for detecting that the optical sensor 6 is located at the first position 6A and the second position 6B, and the control part 8 which drives and controls the card send-out mechanism 4, the card conveyance mechanism 5, the optical sensor 6 and the turning mechanism 7. The control part 8 controls the turning mechanism 7 based on a detection result of the position detection sensor 11. The control part 8 drives the optical sensor 6 to read a code when the position detection sensor 11 detects that the optical sensor 6 is located at the first position 6A. Therefore, a position of the optical sensor 6 can be detected by the position detection sensor 11 and thus, in comparison with a structure that a position of the optical sensor 6 is detected by using a stepping motor or the like provided in the turning mechanism 7, control and structure can be simplified. Further, the control part 8 is capable of driving the optical sensor 6 based on a detection result of the position detection sensor 11 and thus, the optical sensor 6 can be easily driven and controlled.

[0066] In this embodiment, in a case that the optical sensor 6 is driven to perform a reading operation of a code 2b, when reading of the code 2b has failed, the control part 8 drives the turning mechanism 7 to turn the holder 71 for finely adjusting the first position 6A of the optical sensor 6 and then, the control part 8 drives the optical sensor 6 to read the code 2b again. Therefore, a reading direction of the optical sensor 6 can be finely adjusted and thus, when the optical sensor 6 reads the code 2b again, failure of reading of the code 2b can be restrained.

Second Embodiment

[0067] Next, a dust adhesion prevention mechanism 9 in a second embodiment of the present invention will be described below. The dust adhesion prevention mechanism 9 in the second embodiment is a shutter mechanism 12 which is different from the dust adhesion prevention mechanism 9 in the first embodiment. Therefore, in the second embodiment, the same reference signs are used in the same structures as the first embodiment and their descriptions may be omitted. FIG. 10 is a view showing a state that a shutter mechanism 12 has moved a shading member 121 to a first position 12A. FIG. 11 is a view showing a state that the shutter mechanism 12 has moved the shading member 121 to a second position.

[0068] As shown in FIG. 10 and FIG. 11, an optical sensor 6 is fixed to a support member 15 by a screw in a state that a reading face 60 is directed to the Z2 direction side. A dust adhesion prevention mechanism 9 is located on the Y1 direction side with respect to the optical sensor 6 and is fixed to a support member 125. The support member 125 is fixed to a base member 20. In this embodiment, the dust adhesion prevention mechanism 9 is a shutter mechanism 12 structured to move a shading member 121 between a first position 12A where a reading face 60 of the optical sensor 6 is exposed and a second position 12B where the reading face 60 is covered. The shutter mechanism 12 includes the shading member 121 and a drive part 122 which turns the shading member 121 with a turning axis M extended in the Z direction as a center. The drive part 122 includes a motor 123 and an output gear 124 which is engaged with a pinion gear of the motor 123. An end part of a shaft part 124a of the output gear 124 is connected with the shading member 121. A drive force of the motor 123 is transmitted to the shading member 121 through the output gear 124 and thereby, the shading member 121 is moved between the first position 12A and the second position 12B.

[0069] The control part 8 controls the card send-out mechanism 4, the card conveyance mechanism 5, the optical sensor 6 and the shutter mechanism 12. When the optical sensor 6 is used, the control part 8 drives the shutter mechanism 12 to move the shading member 121 to the first position 12A where the reading face 60 is exposed. When the optical sensor 6 is not used, the control part 8 drives the shutter mechanism 12 to move the shading member 121 to the second position 12B where the reading face 60 is covered by the shading member 121. Therefore, when the optical sensor 6 is not used, the reading face 60 of the optical sensor 6 is covered by the shading member 121 and thus, dust can be prevented from adhering to the reading face 60 of the optical sensor 6.

Other Embodiments

[0070] In a case that an integrated circuit (IC) chip is provided in a card 2, the card issuing device may include a reader which is capable of reading and writing to the IC chip. Further, in a case that printing is performed on a surface of a card 2, the card issuing device may include a printing part.

[0071] The card conveyance mechanism 5 is not limited to the above-mentioned structure. For example, in a case that the card issuing device 1 includes a plurality of card storage parts 3 and a plurality of card send-out mechanisms 4 arranged in the Y direction, the card conveyance mechanism 5 may include a carriage capable of moving in the Y direction along a card conveyance passage for receiving a card 2 which is sent out from the respective card send-out mechanisms 4. In this case, the optical sensor 6 may be disposed on the Z1 direction side with respect to the card conveyance passage where the carriage is moved.

[0072] In a case that the holder 71 is turned from the second position 6B to the first position 6A, the optical sensor 6 may include a flexible wiring board 61 which is capable of bending along the bent part 762.
