DETAILED DESCRIPTION OF THE EMBODIMENTS

[0041] Hereinafter, an explanation of embodiments of the present invention will be given in detail with reference to the attached drawings.

[0042] Before the present invention is disclosed and described, it is to be understood that the disclosed embodiments are merely exemplary of the invention, which can be embodied in various forms. Those skilled in the art will envision many other possible variations within the scope of the present invention.

[0043] The present invention may be modified in various ways and may have several exemplary embodiments. Specific exemplary embodiments of the present invention are illustrated in the drawings and described in detail in the detailed description. However, this does not limit the invention within specific embodiments and it should be understood that the invention covers all the modifications, equivalents, and replacements within the idea and technical scope of the invention.

[0044] As shown in FIGS. 2 and 3, a deposit machine according to the present invention includes a body 100, a header housing 200 integrally fixed to one side of the body 100 to detect whether banknotes are counterfeit banknotes and determine whether the banknotes are accommodated, a header cover 210 openably and closably fixed to the header housing 200 by means of a hinge HG to allow top of the header housing 200 to be open, and a large capacity cassette 300 mounted inside the body 100 to accommodate 2,000 or more pieces of banknotes supplied from the header housing 200.

[0045] In this case, as shown in FIG. 4 showing the header housing 200 from which the header cover 210 is separated, the header housing 210 includes a contact image sensor (CIS) 220 as well as the existing IR sensor and MR sensor.

[0046] The CIS 220 is a scan type image sensor that is used in a flatbed scanner almost in direct contact with the object to be scanned.

[0047] The CIS 220 is substantially smaller than a scanner using a charge coupled device (CCD) and uses lower power than the scanner, thereby ensuring efficient operations.

[0048] The CIS 220 is the scan type image sensor, but if the banknotes do not move accurately at a uniform speed, scan images may be deformed to cause a recognition rate to become deteriorated.

[0049] For this reason, the deposit machine according to the present invention does not adopt a direct current (DC) motor, but adopts a stepping motor 230.

[0050] The stepping motor 230 has a rotation angle completely proportional to an input pulse signal, and accordingly, an angle error per one step is small and not accumulated. Further, the stepping motor 230 has good responsibility to motions, stop, and forward and reverse rotations, performs open loop control for the input of pulses such as digital signals, and has a circuit simple in configuration.

[0051] As a result, the stepping motor 230 is used as a motor for driving the banknotes so as to improve the recognition rate of the CIS 220 and accurately read the banknotes.

[0052] According to the present invention, therefore, the IR and MR detection are performed, and further, the images for genuine banknotes are compared with the scanned images. Accordingly, the deposit machine according to the present invention has a function of distinguishing the genuine banknotes and the counterfeit banknotes with at least triple detection results, thereby remarkably improving counterfeit banknote detection capability.

[0053] Further, the cassette 300 is defined as a large capacity accommodation container for stacking 2,000 or more pieces of banknotes.

[0054] As shown in FIGS. 5 to 9, the cassette 300 includes a rectangular box-shaped cassette housing 310 having a space in which banknotes are accommodated, a handle 320 fixed to top of the cassette housing 310, banknote transfer gears 330 disposed on one end portion of one longitudinal side thereof in a direction perpendicular to the handle 320, a lower plate 340 fixed to the opposite side to the surface on which the banknote transfer gears 330 are disposed, and a cassette door 360 fixed to the top end of the lower plate 340 by means of a hinge HIN to open and close an open portion 350.

[0055] In this case, the cassette door 360 has a longer length than the lower plate 340, so that the banknotes stackingly accommodated in the cassette housing 310 can be easily drawn therethrough.

[0056] However, a length of the lower plate 340 has to be greater than and less than of a length of the cassette housing 310, thereby providing the open portion 350 through which the banknotes stackingly accommodated in the cassette housing 310 can be safely drawn, without being spread out, when they are drawn from the cassette housing 310.

[0057] That is, if a length of the open portion 350 is too long, the banknotes are spread out so that they are scattered, and contrarily, if the length is too short, it is inconvenient to draw the banknotes through the open portion 350. Accordingly, the length of the open portion 350 has to be appropriately determined by means of the length adjustment of the lower plate 340 to the above mentioned range.

[0058] Further, the cassette housing 310 has a banknote stacker disposed therein, which is adopted in known deposit machines.

[0059] For example, as shown in FIG. 8, the banknote stacker includes rack gears LG fixed to both inner walls of the cassette housing 310, pinion gears PG movably engaged with the rack gears LG, a loader LD fixed to the pinion gears PG and moving up and down together with the pinion gears PG, and a coil spring SP for providing an elastic restoring force to the loader LD.

[0060] In this case, the rack gears LG are disposed on the side surfaces of a pair of fixed plates facing each other, and the pinion gears PG move up and down in a space between the pair of rack gears LG facing each other. Such a configuration is well known in the art, and as the configuration is not included in the characteristics of the present invention, therefore, an explanation of the configuration will be avoided herein.

[0061] In specific, the deposit machine according to the present invention further includes at least one or more checking members for immediately checking whether a banknote jam occurs while banknotes are inserted, the banknote transfer gears 330 are malfunctioned, and the cassette 300 is mounted on or demounted from the body 100.

[0062] As shown in FIG. 5, the checking members include a pair of first checking members 332a and 332b disposed on one longitudinal side of the cassette housing 310, where the banknote transfer gears 330 are disposed, in a longitudinal direction of the cassette housing 310, while placing the banknote transfer gears 330 therebetween, to detect whether a banknote jam occurs.

[0063] In this case, the first checking members 332a and 332b may be formed of prisms, and if a first light emitting source (not shown) disposed on the header 200 is radiated onto any one of the first checking members 332a and 332b to allow the radiated light to be collected to a first light receiving source (not shown) disposed on the other of the first checking members 332a and 332b, a normal state is determined. However, if the light is not collected to the first light receiving source, it is determined that a banknote jam occurs, so that an error indication and a warning sound corresponding to the banknote jam are provided.

[0064] Further, as shown in FIG. 5, the checking members include a pair of second checking members 334a and 334b disposed in parallel with the banknote transfer gears 330, while placing a detection plate BL moving one time whenever the banknote transfer gears 330 rotate therebetween, to detect whether the banknote transfer gears 330 are malfunctioned.

[0065] In this case, the second checking members 334a and 334b may be formed of prisms, and if a second light emitting source (not shown) disposed on the header 200 is radiated onto any one of the second checking members 334a and 334b to allow the radiated light to be repeatedly collected to a second light receiving source (not shown) disposed on the other of the second checking members 334a and 334b, a normal state is determined. However, if a state where the light is collected or where the light is not collected is maintained, it is determined that the banknote transfer gears 330 are malfunctioned, so that an error indication and a warning sound corresponding to the malfunction are provided.

[0066] In this case, as shown in FIG. 10, a cam CM is formed on a portion of the outer peripheral surface of a gear shaft SF of the banknote transfer gears 330, and a portion of the detection plate BL is seesawably coupled to the gear shaft SF by means of a shaft pin PN, so that when the gear shaft SF rotates one time, the cam CM definitely presses one end of the detection plate BL one time to allow the other end of the detection plate BL to move up to thus cut off or transmit the light emitted and received through the second checking members 334a and 334b.

[0067] As a result, the malfunctions of the banknote transfer gears 3330 can be easily and conveniently detected.

[0068] In addition, as shown in FIG. 5, the checking members include a pair of third checking members 336a and 336b disposed in parallel with the banknote transfer gears 330 at deeper positions than the installation positions of the second checking members 334a and 334b on the outsides of the second checking members 334a and 334b, to detect whether the cassette 300 is mounted on or demounted from the body 100.

[0069] In this case, the third checking members 336a and 336b may be formed of prisms, and if a third light emitting source (not shown) disposed on the header 200 is radiated onto any one of the third checking members 336a and 336b to allow the radiated light to be collected to a third light receiving source (not shown) disposed on the other of the third checking members 336a and 336b, it is determined that the cassette 300 is mounted on the body 100. However, if the light is not collected, it is determined that the cassette 300 is demounted from the body 100.

[0070] Accordingly, the deposit machine according to the present invention is provided with at least one or more checking members, so that it can be operated and managed more conveniently and stably.

[0071] Further, as shown in FIGS. 11 and 12, the cassette door 360 as one of the characteristics of the present invention includes a door sliding plate 362 spaced apart from the inner surface thereof and slidingly moving up and down.

[0072] In this case, the cassette door 360 further includes sliding limitation slots 364 formed on the door sliding plate 362 to limit the moving distance of the door sliding plate 362 and sliding plate restriction members 366 fitted to the sliding limitation slots 364 and fixed thereto.

[0073] Accordingly, the door sliding plate 362 can slide, while maintaining a given distance from the inner surface of the cassette door 360.

[0074] In this case, when the banknotes stack, one end of the banknotes comes into contact with the door sliding plate 362, and in this state, when the banknotes move down to stack, they can move down gently.

[0075] That is, when the banknotes move, if the door sliding plate 362 moves a little, the mobility of the banknotes is improved, so that the banknotes can easily move down.

[0076] In this case, the cassette door 360 has a plurality of ribs RIB spaced apart from one another and protruding from the inner surface thereof, and if the door sliding plate 362 is fitted to the ribs RIB and restricted by the sliding plate restriction members 366, the door sliding plate 362 is suppressed from swinging and performs gentle sliding more accurately.

[0077] The deposit machine according to the present invention is configured to allow the cassette door 360 to openably rotate with respect to the lower plate 340 around the rotation hinge HIN and to locate the door sliding plate 362 on the inner surface of the cassette door 360 to ensure good downward mobility of the banknotes. Such advantages are obtained from the new configuration of the present invention, which is not suggested in the conventional practices.

[0078] Further, the deposit machine according to the present invention is configured to extend the door sliding plate 362 to the lower plate 340 so that the lower plate 340 has the same effectiveness as the cassette door 360. To this end, the lower plate 340 includes a lower sliding plate 342 spaced apart from the inner surface thereof and slidingly moving up and down, sliding limitation slots 344 formed on the lower sliding plate 342 to limit the moving distance of the lower sliding plate 342, and sliding plate restriction members 346 fitted to the sliding limitation slots 344 and fixed thereto.

[0079] Moreover, the lower plate 340 includes a link member 370 adapted to allow the lower sliding plate 342 to interlock with the door sliding plate 362.

[0080] In this case, as shown in FIG. 13, the link member 370 includes a pair of link bars 372 disposed in parallel with each other and H-shaped first and second linkers 374 and 376 fixed to both ends of the pair of link bars 372.

[0081] Further, the lower end of the door sliding plate 362 is rotatably fixed to upper ends of the first and second linkers 374 and 376 by means of hinges.

[0082] To do this, both transverse ends of the lower end of the door sliding plate 362 extend downward.

[0083] Further, the top end of the lower sliding plate 342 is rotatably fixed to lower ends of the first and second linkers 374 and 376 by means of hinges.

[0084] To do this, both transverse ends of the upper end of the lower sliding plate 342 extend upward.

[0085] Under the above-mentioned configuration, when the cassette door 360 is folded to the outside, the door sliding plate 362 and the lower sliding plate 342 are folded to each other around the link member 370, so that the cassette door 360 can rotate to open, without any problem.

[0086] In addition, the door sliding plate 362 and the lower sliding plate 342 are connected to each other by means of the link member 370, so that they can move up and down together.

[0087] As described above, the deposit machine according to the present invention is configured to allow the header to be rotatable by means of the hinge, thereby providing easy maintenance, to have the large capacity cassette for handling 2,000 pieces of banknotes improved in configuration, thereby easily checking the banknote stack and internal state thereof, and to provide the image scanning function, thereby improving the counterfeit banknote detection capability, so that the deposit machine can improve the use conveniences thereof.

[0088] In specific, the deposit machine according to the present invention has the following advantages.

[0089] Firstly, the header is rotatable by means of the hinge, thereby providing easy maintenance for the deposit machine.

[0090] Secondly, all of the CIS, the MR sensor, and the IR sensor are adopted to perform the counterfeit banknote detection, thereby improving the counterfeit banknote detection effectiveness.

[0091] Thirdly, the plurality of prisms are adopted to easily and quickly check whether a banknote jam occurs, the cassette is mounted on or demounted from the body, and the gears are malfunctioned.

[0092] Lastly, the large capacity cassette for handling 2,000 or more pieces of banknotes is improved in configuration, thereby easily checking the banknote stack or the internal state thereof.

[0093] The present invention may be modified in various ways and may have several exemplary embodiments. Accordingly, it should be understood that the invention covers all the modifications, equivalents, and replacements within the idea and technical scope of the invention. Therefore, the present invention is not to be restricted by the embodiments as mentioned above. It is therefore intended that the scope of the invention be limited not by this detailed description, but rather by the claims appended hereto.
