Description

[Technical field]

[0001] The present disclosure relates to a coin processing device, and more particularly to a coin processing device including a temporary storage unit that temporarily stores inserted coins. [Background technology]

[0002] A circulating coin processing device is a device that circulates inserted coins and uses them as coins to be dispensed. Circulating coin processing devices are widely used as station service equipment (automatic ticket vending machines, automatic settlement machines, etc.) or in banks and the like. Some of these coin processing devices are provided with a temporary storage section that temporarily stores inserted coins until the processing of the inserted coins is completed in preparation for the inserted coins being used as coins to be dispensed while the processing of the inserted coins is ongoing. Some of the temporary storage sections are configured to include, for example, a storage tube and a shutter. The storage tube is a cylindrical member having openings at the top and bottom, and stores coins to be temporarily stored inside. The shutter is a rod-shaped member that can close the lower opening of the storage tube, and is movable in both directions so that the locus of the part that closes the lower opening of the storage tube draws an arc around the end opposite to the storage tube. Depending on the direction in which the shutter moves relative to the lower opening of the holding tube, the coins temporarily stored in the holding tube can be dropped into either the storage side or the return side (see, for example, Patent Documents 1 and 2). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2013-122692 A [Patent Document 2] JP 2015-75852 A Summary of the Invention [Problem to be solved by the invention]

[0004] As a mechanism for moving the shutter, the one described in Patent Document 1 uses a cam, while the one described in Patent Document 2 uses a transmission belt. The cam described in Patent Document 1 can move the shutter fixed to the cam by transmitting the power of the motor via gears. However, since this cam is specially molded, the processing work for manufacturing becomes complicated, leading to an increase in costs. On the other hand, the configuration using the transmission belt described in Patent Document 2 requires a distance between the electric motor and the shutter, leading to an increase in the size of the device.

[0005] In view of the above-mentioned problems, the present disclosure relates to providing a coin processing device that has a simple configuration and can be made compact. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, a coin processing device according to a first aspect of the present disclosure comprises a storage tube for storing coins, with an entrance formed at the top through which the coins enter and an exit formed at the bottom through which the coins exit, a coin placement surface that moves on an arc with a radius from a center located away from the exit to the exit, and supports the coins inside the storage tube when the coin placement surface is in a position blocking the exit, a plate-shaped drive plate, a motor that rotates the drive plate, and a plate-shaped driven plate attached to the shutter and moves the shutter by rotating in conjunction with the rotation of the drive plate, one of the drive plate and the driven plate having a protrusion protruding from the plate-shaped surface, and the other having a groove formed therein through which the protrusion is guided within the plate-shaped surface.

[0007] With this configuration, the drive plate and driven plate are plate-shaped, and the engagement between the groove and the protrusion can regulate the rotation of the driven plate and therefore the movement of the shutter, making it possible to reduce the size of the coin processing device with a simple configuration.

[0008] Furthermore, a coin processing device according to a second aspect of the present invention is a coin processing device according to the first aspect of the present disclosure, wherein the protrusion is provided on the surface of the driven plate and the groove is formed in the drive plate.

[0009] With this configuration, the structure of the drive plate can be simplified.

[0010] Furthermore, a coin processing device according to a third aspect of the present invention is a coin processing device according to the second aspect of the present disclosure, wherein the drive plate has a basic shape of an outer edge that is circular, the grooves include a first groove and a second groove that is located on the opposite side of the first groove across a virtual straight line that passes through a drive center about which the drive plate rotates and extends radially, the outer edge between the first groove and the second groove is formed into a small arc that is an arc with a radius smaller than the radius of the basic shape, the driven plate has a protrusion that includes a first protrusion and a second protrusion that is located on the opposite side of the first protrusion across a virtual straight line that passes through a drive center about which the driven plate rotates and extends radially, and the drive plate and the driven plate are positioned such that the first protrusion and the second protrusion are tangent to the small arc when the shutter is in a position to block the outlet.

[0011] With this configuration, the movement of the shutter can be restricted regardless of whether the shutter is moved to a position that blocks the outlet. In addition, when the shutter is in a position that blocks the outlet, the first protrusion and the second protrusion come into contact with the small arc at positions separated from each other, so that the shutter can be stably maintained in that position.

[0012] Further, a coin processing device according to a fourth aspect of the present invention is the coin processing device according to the third aspect of the present disclosure, wherein the first groove and the second groove are formed in a straight line.

[0013] With this configuration, the grooves can be easily formed, and the manufacturing process can be simplified.

[0014] Furthermore, a coin processing device according to a fifth aspect of the present invention is a coin processing device according to the first aspect of the present disclosure, wherein the protrusion is provided on the surface of the drive plate and the groove is formed in the driven plate.

[0015] With this configuration, the drive plate can be made relatively small.

[0016] Furthermore, a coin processing device according to a sixth aspect of the present invention is a coin processing device according to the fourth aspect of the present disclosure, wherein the protrusion of the drive plate includes a first protrusion and a second protrusion located on the opposite side of the first protrusion across a virtual line passing through a drive center which is the center of rotation of the drive plate and extending in a radial direction, the first protrusion is provided on a first virtual arc centered on the drive center and the second protrusion is provided on a second virtual arc centered on the drive center, the groove of the driven plate includes a first groove and a second groove located on the opposite side of the first groove across a virtual line passing through a driven center which is the center of rotation of the driven plate and extending in a radial direction, and the drive plate and the driven plate are positioned such that a portion between the first groove and the second groove protrudes toward the drive center further than the first virtual arc and the second virtual arc between the first protrusion and the second protrusion.

[0017] With this configuration, the movement of the shutter can be restricted regardless of whether the shutter is moved to a position where it blocks the exit.

[0018] Furthermore, a coin processing device according to a seventh aspect of the present invention is a coin processing device according to the sixth aspect of the present disclosure, wherein the drive plate has a surface contact member that rotates around the drive center in association with the rotation of the drive plate around the drive center, and the surface contact member contacts the outer edge of the portion of the driven plate between the first groove and the second groove with a predetermined area when the shutter is in a position to block the outlet.

[0019] With this configuration, it is possible to prevent the shutter from unintentionally moving from the position where it blocks the exit.

[0020] Furthermore, a coin processing device according to an eighth aspect of the present invention is a coin processing device according to any one of the first to seventh aspects of the present disclosure, wherein the drive plate has a lever protruding outward at a position that does not overlap the driven plate.

[0021] With this configuration, it is possible to directly access the drive plate and respond to abnormalities in the storage tube. Effect of the Invention

[0022] According to the present disclosure, the drive plate and driven plate are plate-shaped, and the rotation of the driven plate and therefore the movement of the shutter can be regulated by the engagement between the groove and the protrusion, making it possible to miniaturize the coin processing device with a simple configuration.

[0024] Hereinafter, an embodiment will be described with reference to the drawings. In the drawings, the same or similar reference numerals are used to designate the same or corresponding parts, and duplicated explanations will be omitted.

[0025] First, a coin processing device 1 according to an embodiment will be described with reference to Fig. 1. Fig. 1 is a schematic diagram of the coin processing device 1. The coin processing device 1 mainly comprises an insertion port 2, a payout section 3, a recognition section 5, a sorting section 6, a temporary storage section 10, a storage section 31, a dispensing transport section 35, a dispensing port 39, and a control device 50. The coin processing device 1 according to this embodiment is characterized by the temporary storage section 10 that has a simple configuration and allows for a compact size, but first, the overall configuration of the coin processing device 1 will be outlined.

[0026] The insertion slot 2 is an opening that accepts coins to be processed by the coin processing device 1. The insertion slot 2 is formed to a size that allows multiple coins of the same or different types to be inserted at once. Below the insertion slot 2, a feed unit 3 is provided. The feed unit 3 is a portion that accepts coins inserted from the insertion slot 2 and dispenses the accepted coins one by one at a predetermined interval. The feed unit 3 is formed to a size that allows the amount of coins to be stored that matches the speed at which the coins are dispensed. In addition, the feed unit 3 is typically an inclined type that opens at the bottom. In the case of the inclined type, even if foreign matter is mixed in when multiple coins are inserted at once, it is easy to take measures such as removing the foreign matter by opening the bottom. The coins dispensed from the feed unit 3 are guided to the recognition unit 5 through the insertion path 4. The insertion path 4 may be provided with an openable door so that non-conforming coins such as deformed coins can be removed.

[0027] The recognition unit 5 is a section that recognizes the type of coin. The recognition unit 5 is configured to be able to recognize whether the coin sent from the pay-out unit 3 is a regular coin or not (genuine or not), and to be able to recognize the type of regular coin (typically, the denomination). The recognition unit 5 is configured to be able to output the recognition result to the control device 50 as a signal.

[0028] The sorting unit 6 is a part that sorts the coins sent from the recognition unit 5 according to their types. The sorting unit 6 has a sorting claw that rejects coins other than those that can be stored (typically, non-genuine coins). The sorting claw is typically driven by a sorting claw drive mechanism that is composed of a motor, gears, and the like. In this embodiment, the sorting unit 6 has a sorting plate that has a plurality of sorting holes that pass the target coin but do not pass coins that are one size larger than the target coin so that the coins can be sorted according to their outer shape. Coins that have not been rejected by the sorting claw reach the sorting plate. The plurality of sorting holes formed in the sorting plate are arranged in a line (linearly) from the upstream to the downstream in the direction in which the coins are transported, in order of the diameter of the target coin from the smallest to the smallest. The sorting unit 6 also has a sensor that detects the coins that have passed through each sorting hole and been sorted. This sensor is configured to be able to count the target coins and output the result as a signal to the control device 50.

[0029] A reject return chute 8 is provided below the pay-out unit 3, the insertion path 4, the recognition unit 5, and the sorting unit 6. The reject return chute 8 is a member that forms a passage that guides coins that do not reach the sorting plate of the sorting unit 6 to the dispensing transport unit 35. The reject return chute 8 is formed in a shape and size that can receive any or all of the following: foreign objects removed from the pay-out unit 3, non-conforming coins rejected from the insertion path 4, and coins other than the storable coins sorted by the sorting claw in the sorting unit 6. The reject return chute 8 is also configured to guide the received foreign objects or coins to the dispensing transport unit 35 without allowing them to enter other parts.

[0030] The temporary storage unit 10 is a section that temporarily stores coins sorted by the sorting plate of the sorting unit 6 before storing them in the storage unit 31. The temporary storage unit 10 is configured to temporarily store and store coins inserted from the insertion slot 2 in one procedure, to return the retained coins if they need to be returned during the procedure, and to guide the retained coins to the storage unit 31 after the procedure if they do not need to be returned. Examples of cases in which it is necessary to return retained coins during a procedure include when an instruction to cancel the procedure is given, or when there is a discrepancy between the information identified by the recognition unit 5 and the count by the sorting plate. The configuration of the temporary storage unit 10 will be described later.

[0031] The storage unit 31 is a portion for storing coins that have been sorted by the sorting plate of the sorting unit 6 and temporarily stored in the temporary holding unit 10. The coins stored in the storage unit 31 are circulating coins. The circulating coins are regular coins that are used in circulation so that coins deposited in the coin processing device 1 are dispensed from the coin processing device 1 as change. The storage unit 31 has a hopper cassette 32 for storing coins. A plurality of hopper cassettes 32 are provided so that a plurality of types of coins sorted by the sorting plate of the sorting unit 6 can be stored by type. The plurality of hopper cassettes 32 are placed on a cassette tray 33. In this embodiment, the cassette tray 33 is configured to be pulled out toward the front side of the paper surface, so that each hopper cassette 32 can be pulled out. The storage unit 31 is also configured to be able to release the coins stored in each hopper cassette 32 to the dispensing conveying unit 35 as necessary.

[0032] The dispensing conveying section 35 is a section that conveys coins toward the dispensing port 39. In this embodiment, the dispensing conveying section 35 has a horizontal conveying belt 36 and a vertical conveying belt 37. The horizontal conveying belt 36 is disposed below the coins and foreign objects from the reject return chute 8, the coins returned from the temporary holding section 10, and the coins discharged from the storage section 31 so as to be able to receive these. The horizontal conveying belt 36 is configured to convey the received coins and foreign objects mainly in a horizontal direction toward the side where the dispensing port 39 is provided. The vertical conveying belt 37 conveys the coins and foreign objects conveyed by the horizontal conveying belt 36 to below the dispensing port 39 mainly in a vertical direction to the height of the dispensing port 39. The dispensing port 39 is an opening for discharging the coins and foreign objects conveyed by the dispensing conveying section 35 to the outside of the coin processing device 1.

[0033] The control device 50 controls each part constituting the coin processing device 1. The control device 50 is connected to each of the payout unit 3, the recognition unit 5, the sorting unit 6, the temporary storage unit 10, the storage unit 31, and the dispensing transport unit 35 in a wired or wireless manner so as to be able to communicate with them. When a coin inserted from the insertion port 2 enters the payout unit 3, the control device 50 can operate the payout unit 3 and send the coins in the payout unit 3 toward the insertion path 4 one by one. The control device 50 can also receive information on the type of coins identified by the recognition unit 5. The control device 50 can also operate the sorting claws of the sorting unit 6 according to the result received from the recognition unit 5. The control device 50 can further receive information on the result of counting the coins that have passed through the sorting holes of the sorting unit 6. The control device 50 can also operate the temporary storage unit 10 and execute whether the coins temporarily stored in the temporary storage unit 10 are kept stored, or are guided to the storage unit 31, or are guided to the dispensing transport unit 35. An example of the operation of the temporary holding unit 10 will be described later. The control device 50 can also control whether or not to release coins from each hopper cassette 32 of the storage unit 31. The control device 50 can also control the start and stop of the dispensing conveying unit 35, and can convey coins and foreign objects discharged onto the horizontal conveying belt 36 to the dispensing port 39.

[0034] Next, the configuration of the temporary storage unit 10 in the coin processing device 1 having the schematic configuration as described above will be described with reference mainly to Figs. 2 to 4. Fig. 2 is a front view of the temporary storage unit 10. Fig. 3 is a cross-sectional view taken along line III-III in Fig. 2. Fig. 4 is a diagram of a link structure used when operating in response to a command from the control device 50. The temporary storage unit 10 mainly includes a storage cylinder 11, a passage forming member 12, a shutter 13 (see Fig. 3), a motor 14, a driving plate 15, and a driven plate 16. The link structure shown in Fig. 4 is a combination of the driving plate 15 and the driven plate 16. In this embodiment, a plurality of sets of the storage cylinder 11, the passage forming member 12, and the shutter 13 are provided, but as each set has the same configuration, repeated description will be omitted.

[0035] The storage cylinder 11 is a member that temporarily stores coins sorted by the sorting plate of the sorting unit 6 (see FIG. 1). The storage cylinder 11 is formed in a cylindrical shape so that coins can be stored inside. The storage cylinder 11 is disposed so that the axis of the cylinder extends in the vertical direction so that coins can be stacked and stored vertically. The storage cylinder 11 has an entrance 11e formed on the upper end surface and an exit 11f formed on the lower end surface. The entrance 11e is an opening through which coins enter, and the exit 11f is an opening through which coins exit. In this embodiment, the cross-sectional shape of the storage cylinder 11 (the shape of the cross section perpendicular to the axis) is formed in a quadrangle. The quadrangle of the cross-sectional shape of the storage cylinder 11 is typically a square, but may be a rectangle, or may be a trapezoid, rhombus, or polygon depending on the constraints of the location where the storage cylinder 11 is placed. Alternatively, the cross-sectional shape of the storage cylinder 11 may be a circle or an ellipse. The storage tube 11 is formed so that the area of ​​the space in the cross section perpendicular to the axis can accommodate the largest coin among the coins to be stored. In this embodiment, the area of ​​the space in the cross section perpendicular to the axis is gradually increased from the entrance 11e to the exit 11f. In other words, the internal space of the storage tube 11 is formed to widen from the entrance 11e to the exit 11f.

[0036] The passage forming member 12 is a member that forms a passage that guides the coins discharged from the outlet 11f of the reserve tube 11. As shown in FIG. 3, the passage forming member 12 has two passages, a return passage 12r and a storage passage 12s, formed therein. The return passage 12r is a passage that guides the coins discharged from the outlet 11f to the withdrawal transport section 35 (see FIG. 1) for return. The storage passage 12s is a passage that guides the coins discharged from the outlet 11f to the storage section 31 (see FIG. 1). The return passage 12r extends horizontally downward from the outlet 11f. The storage passage 12s extends horizontally downward from the outlet 11f in a direction opposite to the direction in which the return passage 12r extends. The return passage 12r and the storage passage 12s are each formed to have a size that can receive the shutter 13 when the shutter 13 moves as described below. In this embodiment, the passage forming member 12 is molded integrally with the storage cylinder 11 from synthetic resin. The passage forming member 12 and the storage cylinder 11 may be formed from materials other than synthetic resin, such as metal, but using synthetic resin has the advantage of being lightweight and easy to mold. The passage forming member 12 and the storage cylinder 11 may be formed separately, but by forming them integrally from synthetic resin, manufacturing efficiency can be improved. The integrally molded passage forming member 12 and storage cylinder 11 are preferably transparent so that the inside can be visually confirmed. The passage forming member 12 and / or the storage cylinder 11 may be formed with a hole of a size that does not allow coins to pass through, so that the coins can be touched when a coin jam occurs inside.

[0037] The shutter 13 is a member that blocks the outlet 11f of the reserve tube 11 and has a function of switching whether the coins coming out of the outlet 11f are guided to the return passage 12r or the storage passage 12s. In this embodiment, the shutter 13 is formed in a roughly fan-shape (a figure surrounded by one arc and two radii passing through both ends of the arc) in side view as shown in FIG. 3. In front view (not shown), the shutter 13 is formed in a rectangular shape. The top surface of the shutter 13 on the side where the arc of the fan exists is the coin placement surface 13f. The shutter 13 has a rotation center 13c on the opposite side to the coin placement surface 13f. The rotation center 13c exists at the position where the two radii forming the fan shape intersect. The circumference of the rotation center 13c has a thickness that can surround an axis passing through the rotation center 13c. The rotation center 13c is provided in the passage formation member 12 on the opposite side of the outlet 11f across the return passage 12r and the storage passage 12s. The distance from the rotation center 13c to the coin placement surface 13f of the shutter 13 is substantially the same as the width of the return passage 12r (the same is true for the width of the storage passage 12s) in a side view (see FIG. 3). Therefore, when the coin placement surface 13f is located below the outlet 11f, it blocks the outlet 11f and can receive (support) the weight of the coins stored in the reserve tube 11. The shutter 13 is configured so that the coin placement surface 13f can move in both directions on a virtual circle VC that is an extension of a sector-shaped arc with the rotation center 13c as the center. The direction in which the coin placement surface 13f moves is referred to as the moving direction R. The virtual circle VC is a circular arc with a radius from the rotation center 13c, which is located away from the outlet 11f, to the outlet 11f. "From the center of rotation 13c to the outlet 11f" includes being close enough that the coins in the storage cylinder 11 do not come out of the outlet 11f when the shutter 13 is in a position blocking the outlet 11f. The coin placement surface 13f is formed to a size that encompasses the outlet 11f when it is directly below the storage cylinder 11. It is preferable that the length of the coin placement surface 13f in the movement direction R is formed to be somewhat larger than the width of the outlet 11f in the same direction (having a margin). If there is a margin, it is possible to prevent coins from falling out of the storage cylinder 11 even if there is a positional deviation in the position control of the movement of the shutter 13.When the shutter 13 moves from a state in which the coin placement surface 13f is directly below the exit 11f to enter the storage passage 12s, the inside of the retention cylinder 11 and the return passage 12r are connected (see FIG. 5). On the other hand, when the shutter 13 moves to enter the return passage 12r, the inside of the retention cylinder 11 and the storage passage 12s are connected (see FIG. 6). The shutter 13 cooperates with the passage forming member 12 to form a passage switching mechanism.

[0038] The motor 14 rotates the driving plate 15 in order to move the shutter 13 in the moving direction R via the driving plate 15 and the driven plate 16. A DC motor (direct current motor) is typically used as the motor 14. By using a DC motor as the motor 14, a driving force with high efficiency and excellent controllability can be obtained. However, a stepping motor or an AC servo motor may be used depending on the situation. The motor 14 is configured so that the start / stop and rotation direction of the shaft 14s are controlled by commands from the control device 50. The driving plate 15 is attached to the shaft 14s of the motor 14 so that the driving plate 15 can be rotated.

[0039] The driving plate 15 is a member that mainly transmits the power of the motor 14 to the driven plate 16. As shown in FIG. 2, the driving plate 15 is a plate-shaped member. In this embodiment, the driving plate 15 is formed of a stainless steel plate and has a thickness of 0.8 mm to 1.5 mm, preferably 1.0 mm to 1.2 mm. Since the driving plate 15 is formed in a plate shape, it requires a small installation space, which contributes to the miniaturization of the coin processing device 1. Other materials can be used for the driving plate 15 depending on the usage conditions, and the thickness can be appropriately changed depending on the material to be adopted. The driving plate 15 may be made of a plated steel plate or a synthetic resin plate. There is no limit to the thickness of the driving plate 15 as long as the installation space can be secured, but it is preferable to set it to 5 mm or less or 3 mm or less from the viewpoint of miniaturization, and to set it to 0.6 mm or more from the viewpoint of securing rigidity.

[0040] As shown in FIG. 4, the basic shape of the outer edge of the driving plate 15 is formed in a circular shape. The circular basic shape means that the overall shape can be seen as roughly circular, although there are differences in details. The shaft 14s of the motor 14 is fixed to the center of the basic circular shape of the driving plate 15 via a boss 15B. Hereinafter, the center of the basic circular shape of the driving plate 15 may be referred to as the "driving center 15c". The driving plate 15 is formed with a first groove 15p and a second groove 15q. In this embodiment, the first groove 15p and the second groove 15q are both formed in a straight line and extend parallel to the imaginary straight line VD. The imaginary straight line VD is any one imaginary straight line that passes through the driving center 15c and extends in the radial direction. The first groove 15p and the second groove 15q are parallel to the imaginary straight line VD, so they do not pass through the driving center 15c. In this embodiment, the first groove 15p and the second groove 15q are provided at a position where the virtual straight line VD passes between them. The first groove 15p and the second groove 15q are formed in a straight line, which simplifies processing and improves production efficiency. The first groove 15p and the second groove 15q each have one end in the middle of the circle of the basic shape, and the other end reaching the outer edge. The driving plate 15 has a radius of a circular arc forming the outer edge between the first groove 15p and the second groove 15q of the basic shape, which is smaller than the radius of the circular arc forming the outer edge of the other parts. Hereinafter, the circular arc forming the outer edge between the first groove 15p and the second groove 15q is referred to as the "small circular arc 15a". The radius of the small circular arc 15a is typically smaller than the radius of the circular arc of the other parts by approximately the same amount as the width of the first groove 15p and the second groove 15q. From another perspective, the radius of the small circular arc 15a may be 0.7 to 0.8 times the radius of the arcs of other parts. A lever 15r is provided on the outer edge of the drive plate 15 on the opposite side of the drive center 15c to the small circular arc 15a. The lever 15r typically protrudes outward from the outer edge of the drive plate 15. Providing the lever 15r makes it possible to manually operate the shutter 13 when it is necessary to move the shutter 13 for maintenance or the like.

[0041] The driven plate 16 is a member that moves the shutter 13 by rotating with the rotation of the driving plate 15. The driven plate 16 is connected to the shutter 13 via a driven shaft 16s. As shown in FIG. 2, the driven plate 16 is a plate-shaped member. In this embodiment, the driven plate 16 is made of a stainless steel plate and has a thickness of 0.8 mm to 1.5 mm, preferably 1.0 mm to 1.2 mm. Since the driven plate 16 is formed in a plate shape, it requires a small installation space, which contributes to the miniaturization of the coin processing device 1. Other materials can be used for the driven plate 16 depending on the usage conditions, and the thickness can be appropriately changed depending on the material to be adopted. The material of the driven plate 16 may be a plated steel plate or a synthetic resin plate. There is no limit to the thickness of the driven plate 16 as long as the installation space can be secured, but it is preferably 5 mm or less or 3 mm or less from the viewpoint of miniaturization, and preferably 0.6 mm or more from the viewpoint of securing rigidity.

[0042] As shown in FIG. 4, the outer edge of the driven plate 16 is formed in a circular shape. The driven shaft 16s is fixed to the center of the circle of the driven plate 16 via a boss. The position of the driven plate 16 through which the axis of the driven shaft 16s passes is hereinafter referred to as the "driven center 16c". The shutter 13 is also fixed to the driven shaft 16s (see FIG. 3). The driven shaft 16s extends so that its axis passes through the rotation center 13c of the shutter 13. As described above, in this embodiment, a set of the retaining tube 11, the passage forming member 12, and the shutter 13 is provided in multiple units, and as shown in FIG. 2, multiple shutters 13 are fixed to one driven shaft 16s. The driven plate 16 is disposed at a position where a part of it overlaps with the driving plate 15. In this embodiment, the driven plate 16 is provided at a position where the driven center 16c is located on the virtual straight line VD, and the driven shaft 16s is outside the small arc 15a (typically outside the vicinity of the small arc 15a) when in the reference position. The reference position is the position of each part when the coin placement surface 13f of the shutter 13 blocks the outlet 11f of the storage tube 11.

[0043] As shown in FIG. 4, a first roller 18p and a second roller 18q are provided on the surface of the driven plate 16. The first roller 18p and the second roller 18q protrude from the surface of the driven plate 16 and correspond to a first protrusion and a second protrusion, respectively. The first roller 18p and the second roller 18q are provided at positions where a virtual straight line VD passes between them and where each roller is in contact with the small circular arc 15a when the driven plate 16 is in the reference position. The first roller 18p and the second roller 18q are provided on the driven plate 16 in such a manner that they can rotate around an axis perpendicular to the surface of the driven plate 16. The radius of the small circular arc 15a of the driving plate 15 described above may typically be smaller than the radius of the other arcs by the diameter of the first roller 18p (as well as the diameter of the second roller 18q). In addition, the first groove 15p and the second groove 15q are preferably formed to have a width such that the first roller 18p and the second roller 18q move smoothly in the grooves while minimizing play. When the driven plate 16 is in the reference position (see FIG. 4), the first roller 18p and the second roller 18q are in contact with the small circular arc 15a, so that the shutter 13 can be prevented from moving due to an external force (deadlock). When the driving plate 15 rotates counterclockwise from this state, the first roller 18p is captured by the first groove 15p, and as the driving plate 15 further rotates counterclockwise, the first roller 18p goes deeper into the first groove 15p, and the driven plate 16 rotates clockwise. This state is shown in FIG. 5. On the other hand, when the driving plate 15 rotates clockwise from the reference position, the second roller 18q is captured by the second groove 15q, and then the second roller 18q enters deeper into the second groove 15q, causing the driven plate 16 to rotate counterclockwise. This state is shown in Figure 6. With such rotation of the driven plate 16, the multiple shutters 13 connected to the driven plate 16 via the driven shaft 16s rotate simultaneously in the same direction as the driven plate 16. Note that in Figures 5 and 6, the driving plate 15 and the driven plate 16, which are not actually shown in the cross section, are shown by dashed lines in order to show the positional relationship between the driving plate 15 and the driven plate 16 and the shutters 13.

[0044] As shown in FIG. 7 and FIG. 2, the temporary holding section 10 may include a position sensor 20 that detects the position of the shutter 13 in addition to the above configuration. The position sensor 20 has a detection piece 21 and three detection sensors 22a, 22b, and 22c. The position sensor 20 is configured to detect the position of an object based on whether the light emitted by the detection sensor 22 is transmitted or blocked by the detection piece 21. The detection piece 21 is a thin plate-like small piece formed in a fan shape. The center of the fan shape of the detection piece 21 is attached to the driven shaft 16s, and the arc part of the fan shape rotates and moves with the rotation of the driven shaft 16s. The three detection sensors 22a, 22b, and 22c are arranged at the following positions. When the shutter 13 is in the reference position, the detection sensor 22a is light-blocking and the detection sensors 22b and 22c are light-transmitting. When the shutter 13 enters the storage passage 12s (see FIG. 5), the detection sensor 22b becomes light-shielding and the detection sensors 22a and 22c become light-transmitting. When the shutter 13 enters the return passage 12r (see FIG. 6), the detection sensor 22c becomes light-shielding and the detection sensors 22a and 22b become light-transmitting.

[0045] The operation of the coin processing device 1 will be described with continued reference to Fig. 1 mainly, and with reference to Figs. 2 to 7 as appropriate when referring to the configuration of the temporary storage unit 10. In the coin processing device 1, the shutter 13 in the temporary storage unit 10 is normally in a reference position (a position where the outlet 11f of the storage tube 11 is blocked by the coin placing surface 13f of the shutter 13). At this time, as shown in Fig. 4, a portion of the small circular arc 15a of the drive plate 15 adjacent to the first groove 15p and the second groove 15q and a first roller 18p and a second roller 18q attached to the driven plate 16 form a deadlock portion.

[0046] During operation, the coin processing device 1 waits for coins to be inserted from the insertion port 2. When one or more coins are inserted into the coin processing device 1 from the insertion port 2, the inserted coins are stored in the payout section 3. The coins stored in the payout section 3 are separated one by one and transported to the insertion path 4 one by one. If foreign objects (including deformed coins of a predetermined size or more) are included in the coins inserted in a lump into the insertion port 2, the foreign objects are not transported to the insertion path 4 and remain in the payout section 3. The foreign objects remaining in the payout section 3 fall into the reject return chute 8, for example, by opening an openable door provided at the bottom at a suitable time. If deformed coins that cannot pass through the insertion path 4 are included among the coins that are paid out from the payout section 3 and are about to pass through the insertion path 4, the openable door can be opened to remove the deformed coins. The deformed coins can typically be removed manually, but if they cannot be removed successfully, they fall into the reject return chute 8. Foreign objects that fall from the pay-out section 3 into the reject return chute 8, or deformed coins that fall from the insertion path 4 into the reject return chute 8, then fall onto the horizontal conveying belt 36, are transported by the dispensing conveying section 35, and are released into the dispensing port 39.

[0047] The coins that have passed through the insertion path 4 are transported to the recognition unit 5. When the coins pass through the recognition unit 5, the recognition unit 5 recognizes the type of the coin and transmits the recognition result to the control device 50. If the coins recognized by the recognition unit 5 are not deemed to be genuine, the control device 50 operates the sorting claw when the coins reach the sorting unit 6, causing the coins to fall into the reject return chute 8. The coins that have entered the reject return chute 8 fall onto the horizontal conveyor belt 36, are conveyed by the withdrawal conveyor unit 35, and are discharged into the withdrawal port 39. On the other hand, if the coins recognized by the recognition unit 5 are deemed to be genuine, the coins that have entered the sorting unit 6 are not rejected by the sorting claw, and reach the sorting plate. The coins that have reached the sorting plate pass through the corresponding sorting holes, are counted by a sensor, and enter the temporary storage unit 10 according to type. At this time, since the shutter 13 of the temporary storage unit 10 is in the reference position, the coins that have entered the storage cylinder 11 from the entrance 11e are placed on the coin placement surface 13f of the shutter 13 without flowing out from the exit 11f, and are piled up in the storage cylinder 11.

[0048] The coin processing device 1 compares the total amount of the inserted coins with the transaction amount by the control device 50, and if no change (withdrawal) is required, the coins are stored in the storage tube 11 and wait for the next user to deposit. On the other hand, when the user who inserted the coins continues to operate and performs a return operation, the control device 50 operates the motor 14 so that the driving plate 15 in the state shown in FIG. 4 rotates counterclockwise. When the driving plate 15 rotates counterclockwise, the first groove 15p captures the first roller 18p of the driven plate 16, and as the driving plate 15 rotates further, the first roller 18p penetrates deeper into the first groove 15p, and the driven plate 16 rotates clockwise accordingly. When the driven plate 16 rotates clockwise, the shutter 13 connected to the driven plate 16 via the driven shaft 16s moves in synchronization with the driven plate 16 and enters the storage passage 12s. When the shutter 13 enters the storage passage 12s completely, and the detection sensor 22b in the position sensor 20 becomes light-shielded and the detection sensors 22a and 22c become light-transmitting, the control device 50 stops the operation of the motor 14. When the shutter 13 enters the storage passage 12s, as shown in FIG. 5, the outlet 11f of the reserve tube 11 is opened, and the reserve tube 11 and the return passage 12r are connected. As a result, the coins stored in the reserve tube 11 flow out from the outlet 11f, pass through the return passage 12r, and reach the horizontal conveyor belt 36. The control device 50 starts the dispensing conveyor unit 35 when the return operation is performed, and the coins that reach the horizontal conveyor belt 36 are discharged to the dispensing port 39 via the horizontal conveyor belt 36.

[0049] When the shutter 13 is in the reference position, the coins are stored in the storage tube 11, and the machine is waiting for the next user to deposit the coins, the following occurs. When the operation of the user who deposited the coins is completed and the next user deposits the coins into the slot while waiting for the next user to deposit the coins, the control device 50 operates the motor 14 so that the driving plate 15 shown in FIG. 4 rotates clockwise. When the driving plate 15 rotates clockwise, the second groove 15q captures the second roller 18q of the driven plate 16, and as the driving plate 15 rotates further, the second roller 18q penetrates deeper into the second groove 15q, and the driven plate 16 rotates counterclockwise. When the driven plate 16 rotates counterclockwise, the shutter 13 moves in synchronization with the driven plate 16 and enters the return passage 12r. When the shutter 13 enters the return passage 12r completely, and the detection sensor 22c in the position sensor 20 becomes light-shielded and the detection sensors 22a and 22b become light-transmitting, the control device 50 stops the operation of the motor 14. When the shutter 13 enters the return passage 12r, the outlet 11f of the reserve cylinder 11 is opened as shown in Fig. 6, and the reserve cylinder 11 and the storage passage 12s are connected. As a result, the coins stored in the reserve cylinder 11 flow out from the outlet 11f, pass through the storage passage 12s, and enter each hopper cassette 32 of the storage unit 31 by type.

[0050] Going back a little, the control device 50 compares the total amount of the inserted coins with the transaction amount, and if there is change (withdrawal), proceeds to the withdrawal operation. When the withdrawal operation is to be performed, the control device 50 moves the horizontal conveyor belt 36 and the vertical conveyor belt 37 of the withdrawal conveyor section 35 to discharge the amount of coins to be withdrawn from the storage section 31 and move them to the withdrawal port 39. After the change is discharged to the withdrawal port 39, the machine returns to a state of waiting for the insertion of coins from the insertion port 2 again, and thereafter repeats the above-mentioned operations.

[0051] When coins are stored in the storage tube 11, an abnormality may occur such as the coin becoming stuck in the storage tube 11 due to the coin becoming upright with its face not facing up or down. When an abnormality occurs, the coin processing device 1 stops and maintenance such as removing the jammed coins is performed. During maintenance, the lever 15r of the drive plate 15 is used to move the drive plate 15, so that the coins remaining in the storage tube 11 can be guided to the return passage 12r or the storage passage 12s. After the control device 50 confirms the signal output from the position sensor 20 by a reset operation after maintenance, the control device 50 moves the shutter 13 to the reference position.

[0052] As described above, according to the coin processing device 1 of this embodiment, since the driving plate 15 and the driven plate 16 are formed in a plate shape, it is possible to reduce the size of the temporary storage unit 10, and therefore the size of the coin processing device 1. Furthermore, since the link mechanism is configured by forming the linear first groove 15p and second groove 15q in the driving plate 15 and providing the first roller 18p and the second roller 18q in the driven plate 16, which fit into these grooves, manufacturing is simplified and manufacturing efficiency can be improved.

[0053] Next, a modified example of the driving plate and the driven plate will be described with reference to FIG. 8. The driving plate 115 and the driven plate 116 according to the modified example are mainly different from the driving plate 15 and the driven plate 16 (see FIG. 4) in that the positional relationship between the formation of the grooves and the installation of the rollers is reversed. That is, the driving plate 115 is provided with a first roller 118p and a second roller 118q. The driven plate 116 is formed with a first groove 116p and a second groove 116q. The driving plate 115 and the driven plate 116 according to this modified example are members that replace the driving plate 15 and the driven plate 16 (see FIG. 4) in the temporary storage unit 10 (see FIG. 2) of the coin processing device 1 (see FIG. 1), and function in cooperation with other members of the temporary storage unit 10 such as the shutter 13 and the storage tube 11. Therefore, in the following description of the driving plate 115 and the driven plate 116 according to the modified example, when other members of the temporary storage unit 10 are mentioned, the relevant figures will be referred to as appropriate.

[0054] The driving plate 115 is a plate-like member, and its material and thickness can be determined in the same way as the driving plate 15 (see FIG. 4). The driving plate 115 has a circular basic shape on the outer edge. The shaft 14s of the motor 14 is fixed to the center of the circular basic shape of the driving plate 115 via a boss 115B. The boss 115B has a protrusion 115t protruding radially outward on a part of the circumference forming the outer edge. The protrusion 115t is provided on a virtual straight line VD. The virtual straight line VD is an arbitrary virtual straight line that passes through the driving center 115c and extends in the radial direction. A first roller 118p and a second roller 118q are provided on the surface of the driving plate 115. The first roller 118p and the second roller 118q protrude from the surface of the driving plate 115 and correspond to a first protrusion and a second protrusion, respectively. The first roller 118p and the second roller 118q are provided at positions sandwiching a virtual line VD therebetween. In this modification, the first roller 118p and the second roller 118q are provided at positions where the virtual line VD passes through the midpoint of a virtual line segment (not shown) connecting the first roller 118p and the second roller 118q at the reference position. However, depending on the design of the movement amount of the shutter 13, the distance from the virtual line VD to the first roller 118p and the distance from the virtual line VD to the second roller 118q may be different.

[0055] The first roller 118p is provided on the first virtual arc VP. The second roller 118q is provided on the second virtual arc VQ. The first virtual arc VP and the second virtual arc VQ are both virtual arcs that are centered on the drive center 115c, have a radius smaller than the outer edge of the drive plate 115, and have a radius larger than the distance from the drive center 115c to the tip of the convex portion 115t. Since the first virtual arc VP and the second virtual arc VQ have the same radius in this modification, they can be integrated into one virtual arc. However, depending on the design, the first virtual arc VP and the second virtual arc VQ may have different radii. The first roller 118p and the second roller 118q are provided on the drive plate 115 in such a manner that they can rotate around an axis perpendicular to the surface of the drive plate 115. The drive plate 115 is also provided with a lever 115r. The lever 115r may be provided at an appropriate position, taking into consideration that the shutter 13 can be manually operated when it is necessary to move the shutter 13 for maintenance or the like.

[0056] The driven plate 116 is a plate-like member, and its material and thickness can be determined in the same way as the driven plate 16 (see FIG. 4). The driven plate 116 has a circular basic shape on its outer edge. The driven plate 116 is connected to the shutter 13 via the driven shaft 16s, like the driven plate 16 (see FIG. 4). The driven plate 116 and the driven shaft 16s are fixed via a boss. The driven plate 116 is disposed at a position where the driven center 116c is on the virtual straight line VD. The driven plate 116 is formed with a first groove 116p and a second groove 116q. The first groove 116p and the second groove 116q extend along the virtual straight line VD. The first groove 116p and the second groove 116q are disposed at a position where the virtual straight line VD passes between them in the reference position. The first groove 116p and the second groove 116q each have one end in the middle of the circle of the basic shape, and the other end reaching the outer edge. The first groove 116p and the second groove 116q are preferably formed with a width that allows the first roller 118p and the second roller 118q to enter the groove while minimizing play. The depth of the first groove 116p and the second groove 116q may be appropriately determined in consideration of the intended degree of movement of the driven plate 116.

[0057] The portion of the driven plate 116 between the first groove 116p and the second groove 116q is referred to as the inter-groove portion 116t. The driven plate 116 is disposed at a position where a part of the driven plate 116 overlaps the driving plate 115 in a positional relationship where the tip of the inter-groove portion 116t (the circular outer edge portion of the basic shape in the inter-groove portion 116t) protrudes toward the driving center 115c beyond the first imaginary arc VP and the second imaginary arc VQ. In addition, the driven plate 116 is configured such that the portion of the first groove 116p that reaches the circular outer edge of the basic shape is on the first imaginary arc VP when the driven plate 116 is in the reference position. Similarly, the driven plate 116 is configured such that the portion of the second groove 116q that reaches the circular outer edge of the basic shape is on the second imaginary arc VQ when the driven plate 116 is in the reference position. Furthermore, when the driven plate 116 is in the reference position, the tip of the groove portion 116t contacts the tip of the protrusion 115t of the driving plate 115 with a predetermined area. The predetermined area is an area that can form a deadlock portion that can prevent the shutter 13 from moving due to an external force by the tip of the protrusion 115t contacting the tip of the groove portion 116t. The protrusion 115t of the driving plate 115 that contacts the tip of the groove portion 116t with a predetermined area corresponds to a surface contact member.

[0058] When the driving plate 115 and the driven plate 116 according to this modified example, which are configured as described above, rotate counterclockwise from a state in which the driving plate 115 is in the reference position, the first roller 118p enters the first groove 116p. The first roller 118p that has entered the first groove 116p abuts against the side wall of the inter-groove portion 116t (the portion of the inter-groove portion 116t that is the boundary portion with the first groove 116p) and then pushes the inter-groove portion 116t. The driven plate 116, whose inter-groove portion 116t is pushed by the first roller 118p, rotates clockwise. In synchronization with this clockwise rotation of the driven plate 116, the shutter 13 moves and enters the storage passage 12s. When the shutter 13 enters the storage passage 12s completely, and the detection sensor 22b in the position sensor 20 becomes light-shielded and the detection sensors 22a and 22c become light-transmitting, the control device 50 stops the counterclockwise rotation of the driving plate 115. When the shutter 13 enters the storage passage 12s, the reserve tube 11 and the return passage 12r are connected. On the other hand, when the driving plate 115 rotates clockwise from the state in which the driving plate 115 and the driven plate 116 are in the reference position, the second roller 118q enters the second groove 116q. The second roller 118q that enters the second groove 116q hits the side wall of the groove portion 116t and then pushes the groove portion 116t. The driven plate 116, whose groove portion 116t is pushed by the second roller 118q, rotates counterclockwise. The shutter 13 moves in synchronization with the counterclockwise rotation of the driven plate 116 and enters the return passage 12r. When the shutter 13 enters the return passage 12r completely, and the detection sensor 22c in the position sensor 20 becomes light-shielded and the detection sensors 22a and 22b become light-transmitting, the clockwise rotation of the drive plate 115 is stopped by the control device 50. When the shutter 13 enters the return passage 12r, the reserve tube 11 and the storage passage 12s are connected.

[0059] In this manner, the driving plate 115 and the driven plate 116 according to this modification can appropriately operate the temporary storage unit 10 by replacing the driving plate 15 and the driven plate 16 (see FIG. 4). In the driving plate 115 and the driven plate 116 according to this modification, both are formed in a plate shape, so that the temporary storage unit 10 can be made smaller, and the coin processing device 1 can be made smaller. In addition, the first roller 118p and the second roller 118q are provided on the driving plate 115, and the first groove 116p and the second groove 116q into which these rollers fit are formed on the driven plate 116 to configure a link mechanism, so that manufacturing is simplified and manufacturing efficiency can be improved. In addition, the driving plate 115 is provided with the first roller 118p and the second roller 118q, and no grooves are formed, so that the driving plate 115 can be made smaller than the driving plate 15 (see FIG. 4). The configuration of the driving plate 15 and the driven plate 16 shown in FIG. 4 has the advantage that the distance between the first roller 18p and the second roller 18q that contact the small circular arc 15a in the reference position can be made relatively large, thereby improving the deadlock performance.

[0060] In the above description, the first groove 15p and the second groove 15q of the driving plate 15 shown in Fig. 4 are formed in a straight line, but they may be formed in a curved shape such as a circular arc or an elliptical arc depending on the design of the movement mode of the shutter 13. However, forming the first groove 15p and the second groove 15q in a straight line has the advantage of simplifying the processing.

[0061] In the above description, the basic shape of the outer edge of the driving plates 15, 115 is circular, but it may be formed in a shape other than circular (for example, a regular polygon such as a rectangle, hexagon, or octagon). However, a circular shape is preferable because it minimizes the space required when rotating. Similarly, the basic shape of the outer edge of the driven plates 16, 116 may be a shape other than circular, but is preferably circular for the same reasons as the driving plates 15, 115.

[0062] In the above description, the lever 15r is provided on the opposite side of the small circular arc 15a across the drive center 15c of the drive plate 15, but the position is not limited to this and it may be provided in any position where it can be operated without overlapping with the driven plate 16. Furthermore, the levers 15r, 115r are of any configuration, and in cases where the shutter 13 can be moved for maintenance or the like without providing the levers 15r, 115r, the levers 15r, 115r can be omitted.

[0063] In the above description, the virtual line passing through the driving center 15c and the virtual line passing through the driven center 16c are the same virtual line VD, but they may be virtual lines extending at different angles (not coinciding). The same applies to the virtual line passing through the driving center 115c and the virtual line passing through the driven center 116c. [Explanation of symbols]
