Further, the control device 50 can control the start and stop of the withdrawal transfer unit 35 to convey the coins and foreign substances discharged to the horizontal transfer belt 36 to the withdrawal port 39.

Next, with reference mainly to FIGS. 2 to 4, the configuration of the temporary holding unit 10 in the coin processing apparatus 1 having the above-mentioned schematic configuration will be described. FIG. 2 is a front view of the temporary holding portion 10. FIG. 3 is a sectional view taken along line III-III in FIG. FIG. 4 is a diagram of a link structure used when operating by a command from the control device 50. The temporary holding portion 10 mainly has a holding cylinder 11, a passage forming member 12, a shutter 13 (see FIG. 3), a motor 14, a drive plate 15, and a driven plate 16. The link structure shown in FIG. 4 is a combination of a drive plate 15 and a driven plate 16. In the present embodiment, a plurality of sets of the holding cylinder 11, the passage forming member 12, and the shutter 13 are provided, but since each has the same configuration, duplicate description will be omitted.

The holding cylinder 11 is a member for temporarily storing coins sorted by the sorting plate of the sorting unit 6 (see FIG. 1). The holding cylinder 11 is formed in a cylindrical shape so that coins can be stored inside. Further, the holding cylinder 11 is arranged so that the axis of the cylinder extends in the vertical direction so that coins can be stacked and stored in the vertical direction. The holding cylinder 11 has an inlet 11e formed on the upper end surface and an outlet 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 enter. The cross-sectional shape of the holding cylinder 11 (the shape of the cross-section orthogonal to the axis) is formed into a quadrangle in the present embodiment. The quadrangle having a cross-sectional shape of the holding cylinder 11 is typically a square, but may be a rectangle, or may be a trapezoid, a rhombus, or a polygon depending on the restriction of the place where the holding cylinder 11 is arranged. Alternatively, the cross-sectional shape of the holding cylinder 11 may be circular or elliptical. The holding cylinder 11 is formed so that the area of the space in the cross section orthogonal to the axis is large enough to accommodate the largest coin to be accommodated. In the present embodiment, the area of the space in the cross section orthogonal to the axis is formed so as to gradually increase from the inlet 11e to the exit 11f. In other words, the internal space of the holding cylinder 11 is formed so as to expand toward the exit 11f from the inlet 11e.

The passage forming member 12 is a member that forms a passage for guiding coins exiting from the outlet 11f of the holding cylinder 11. As shown in FIG. 3, the passage forming member 12 has two passages, a return passage 12r and a storage passage 12s. The return passage 12r is a passage that guides the coins from the exit 11f to the withdrawal transfer unit 35 (see FIG. 1) for return. The storage passage 12s is a passage that guides coins from the outlet 11f to the storage portion 31 (see FIG. 1). The return passage 12r extends horizontally downward from the exit 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 a size that can accept the shutter 13 when the shutter 13 moves as described later. In the present embodiment, the passage forming member 12 is integrally molded with the holding cylinder 11 with synthetic resin. The passage forming member 12 and the holding cylinder 11 may be made of a material other than synthetic resin such as metal, but if synthetic resin is used, there is an advantage that weight reduction can be achieved and molding is easy. Further, although the passage forming member 12 and the holding cylinder 11 may be formed separately, the manufacturing efficiency can be improved by integrally forming the passage forming member 12 with the synthetic resin. It is preferable that the integrally molded passage forming member 12 and the holding cylinder 11 are transparent so that the inside can be visually recognized. Further, the passage forming member 12 and / or the holding cylinder 11 may be formed with a hole having a size that the coin cannot pass through so that the coin can be touched when the coin is jammed inside.

The shutter 13 is a member having a function of closing the outlet 11f of the holding cylinder 11 and switching whether the coins coming out of the outlet 11f are guided to the return passage 12r or the storage passage 12s. In the present embodiment, as shown in FIG. 3, the shutter 13 is formed in a substantially fan shape (a figure surrounded by one arc and two radii passing through both ends thereof) in a side view. It is formed in a rectangular shape when viewed from the front (not shown). The top surface of the shutter 13 on the side where the fan-shaped arc exists is the coin placing surface 13f. The shutter 13 has a rotation center 13c on the opposite side of the coin placing surface 13f. The center of rotation 13c exists at a position where two radii forming a fan shape intersect. The circumference of the rotation center 13c has a thickness capable of surrounding an axis passing through the rotation center 13c. The rotation center 13c is provided on the passage forming member 12 on the opposite side of the return passage 12r and the storage passage 12s with respect to the outlet 11f. In the shutter 13, the distance from the rotation center 13c to the coin loading surface 13f is substantially the same as the width of the return passage 12r (the width of the storage passage 12s is also the same) in the side view (see FIG. 3). Therefore, when the coin loading surface 13f is below the outlet 11f, the outlet 11f can be closed and the weight of the coin housed in the holding cylinder 11 can be received (supporting the coin). .. The shutter 13 is configured so that the coin placing surface 13f can move in both directions on a virtual circle VC extending a fan-shaped arc with the rotation center 13c as the center. The direction in which the coin placing surface 13f moves is referred to as the movement direction R. The virtual circle VC is an arc whose radius is from the rotation center 13c existing at a position away from the outlet 11f to the exit 11f. "From the center of rotation 13c to the exit 11f" includes the fact that the coins in the holding cylinder 11 are separated so close that they do not come out of the outlet 11f when the shutter 13 is in the position of closing the outlet 11f. The coin loading surface 13f is formed to have a size including the outlet 11f when it is directly below the holding cylinder 11. The coin loading surface 13f is preferably formed so that the length of the moving direction R is larger than the width of the exit 11f in the same direction (has a margin). If the margin is provided, it is possible to prevent the coin from falling off from the holding cylinder 11 even when the position control of the movement of the shutter 13 is displaced. When the shutter 13 moves so as to enter the storage passage 12s from the state where the coin loading surface 13f is directly below the outlet 11f, the inside of the holding cylinder 11 and the return passage 12r are in contact with each other (see FIG. 5). On the other hand, when the shutter 13 moves so as to enter the return passage 12r, the inside of the holding cylinder 11 and the storage passage 12s are in contact with each other (see FIG. 6). The shutter 13 cooperates with the passage forming member 12 to form a passage switching mechanism.

The motor 14 rotates the drive plate 15 in order to move the shutter 13 in the moving direction R via the drive plate 15 and the driven plate 16. As the motor 14, a DC motor (DC motor) is typically used. By using a DC motor as the motor 14, it is possible to obtain a driving force with high efficiency and excellent controllability. However, depending on the situation, a stepping motor or an AC servomotor may be used. The motor 14 is configured such that the start / stop and the rotation direction of the rotation of the shaft 14s are controlled by a command from the control device 50. In the motor 14, the drive plate 15 is attached to the shaft 14s so that the drive plate 15 can be rotated.

The drive 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 drive plate 15 is a plate-shaped member. In the present embodiment, the drive plate 15 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 drive plate 15 is formed in a plate shape, the installation space can be small, which contributes to the miniaturization of the coin processing device 1. Other materials can be used for the drive plate 15 according to the usage conditions, and the thickness can be appropriately changed according to the material to be adopted. As the material of the drive plate 15, a plated steel plate or a synthetic resin plate may be used. The thickness of the drive plate 15 is not limited 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 0.6 mm or more from the viewpoint of ensuring rigidity. It is preferable to do.

As shown in FIG. 4, the drive plate 15 has a circular outer edge. The fact that the basic shape here is circular means that although there are differences in details, it can be seen as a circle as a whole. In the drive plate 15, the shaft 14s of the motor 14 is fixed to the center of the circular shape of the basic shape via the boss 15B. Hereinafter, the circular center of the basic shape of the drive plate 15 may be referred to as a “drive center 15c”. The drive plate 15 is formed with a first groove 15p and a second groove 15q. In the present embodiment, the first groove 15p and the second groove 15q are both formed in a straight line and extend in parallel with the virtual straight line VD. The virtual straight line VD is any one virtual straight line extending in the radial direction through the drive center 15c. Since the first groove 15p and the second groove 15q are parallel to the virtual straight line VD, they do not pass through the drive center 15c. In the present embodiment, the first groove 15p and the second groove 15q are provided at positions where a virtual straight line VD passes between the first groove 15p and the second groove 15q. Since the first groove 15p and the second groove 15q are formed in a linear shape, processing becomes easy and production efficiency can be improved. Each of the first groove 15p and the second groove 15q has one end in the middle of a circular shape having a basic shape and the other end reaching the outer edge. In the drive plate 15, the radius of the arc forming the outer edge between the first groove 15p and the second groove 15q, which is circular in the basic shape, is smaller than the radius of the arc forming the outer edge of the other portion. There is. Hereinafter, the arc forming the outer edge between the first groove 15p and the second groove 15q will be referred to as a “small arc 15a”. The radius of the small arc 15a is typically smaller than the radius of the arc of the other portion by the same extent as the width of the first groove 15p and the second groove 15q. From another point of view, the radius of the small arc 15a may be 0.7 to 0.8 times the radius of the arc of the other portion. The drive plate 15 is provided with a lever 15r on the outer edge on the opposite side of the small arc 15a with the drive center 15c interposed therebetween. The lever 15r typically projects outward from the outer edge of the drive plate 15. Since the lever 15r is provided, the shutter 13 can be manually operated when it is necessary to move the shutter 13 for maintenance or the like.

The driven plate 16 is a member that moves the shutter 13 by rotating with the rotation of the drive plate 15. The driven plate 16 is connected to the shutter 13 via the driven shaft 16s. As shown in FIG. 2, the driven plate 16 is a plate-shaped member. In the present 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, the installation space can be small, which contributes to the miniaturization of the coin processing device 1. Other materials can be used for the driven plate 16 according to the usage conditions, and the thickness can be appropriately changed according to the material to be adopted. As the material of the driven plate 16, a plated steel plate or a synthetic resin plate may be used. The thickness of the driven plate 16 is not limited 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 0.6 mm or more from the viewpoint of ensuring rigidity. It is preferable to do.

As shown in FIG. 4, the driven plate 16 has a circular outer edge. In the driven plate 16, the driven shaft 16s is fixed to the center of the circle via a boss. The position of the driven plate 16 through which the axis of the driven shaft 16s penetrates is hereinafter referred to as "driven center 16c". A shutter 13 is also fixed to the driven shaft 16s (see FIG. 3). The driven shaft 16s extends so that its axis extends through the rotation center 13c of the shutter 13. As described above, in the present embodiment, a plurality of sets of the holding cylinder 11, the passage forming member 12, and the shutter 13 are provided, and as shown in FIG. 2, a plurality of shutters 13 are provided on one driven shaft 16s. Is fixed. The driven plate 16 is arranged at a position where a part thereof overlaps with the driving plate 15. In the present embodiment, in the driven plate 16, the driven axis 16s 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) at the reference position. It is provided at the position where. The reference position is the position of each part when the coin placing surface 13f of the shutter 13 is closed with the outlet 11f of the holding cylinder 11.

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 project from the surface of the driven plate 16 and correspond to the first protrusion and the second protrusion, respectively. The first roller 18p and the second roller 18q are provided at positions where the driven plate 16 is in the reference position, a virtual straight line VD passes between them, and each of them is in contact with the small arc 15a. The first roller 18p and the second roller 18q are provided on the driven plate 16 in such a manner that they can rotate about an axis perpendicular to the surface of the driven plate 16, respectively. Even if the radius of the small arc 15a of the drive plate 15 described above is typically smaller than the radius of the arc of the other portion by the diameter of the first roller 18p (the same applies to the diameter of the second roller 18q). good. Further, it is preferable that the first groove 15p and the second groove 15q are formed so as to have a width in which the first roller 18p and the second roller 18q, respectively, move smoothly in the groove and minimize play. In the driven plate 16 configured in this way, 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 arc 15a, so that the shutter 13 moves by an external force. Can be blocked (deadlock). From this state, when the drive plate 15 rotates counterclockwise, the first roller 18p is captured by the first groove 15p, and as the drive plate 15 rotates counterclockwise, the first roller 18p becomes the first groove 15p. The driven plate 16 rotates clockwise as it goes deeper. This state is shown in FIG. On the other hand, when the drive 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 penetrates deep into the second groove 15q, so that the driven plate 16 Rotates counterclockwise. This state is shown in FIG. With the rotation of the driven plate 16, the plurality of shutters 13 connected to the driven plate 16 via the driven shaft 16s rotate simultaneously in the same direction as the driven plate 16. In FIGS. 5 and 6, in order to show the positional relationship between the drive plate 15 and the driven plate 16 and the shutter 13, the drive plate 15 and the driven plate 16 that do not originally appear in the cross section are shown by broken lines.

As shown in FIGS. 7 and 2, the temporary holding unit 10 may include a position sensor 20 for detecting 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 be able to detect the position of an object depending on whether the light emitted by the detection sensor 22 is transmitted or shielded by the detection piece 21. The detection piece 21 is a thin plate-shaped small piece formed in a fan shape. In the detection piece 21, the center of the fan shape is attached to the driven shaft 16s, and the arcuate portion of the fan shape rotates and moves as the driven shaft 16s rotates. 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 shielded from light, and the detection sensors 22b and 22c are transparent. When the shutter 13 enters the storage passage 12s (see FIG. 5), the detection sensor 22b is shielded from light and the detection sensors 22a and 22c are transparent. When the shutter 13 enters the return passage 12r (see FIG. 6), the detection sensor 22c is shielded from light and the detection sensors 22a and 22b are transparent.

Subsequently, FIG. 1 will be mainly referred to, and when the configuration of the temporary holding unit 10 is referred to, the operation of the coin processing apparatus 1 will be described with reference to FIGS. 2 to 7 as appropriate. In the coin processing device 1, the shutter 13 in the temporary holding portion 10 is usually at a reference position (a position where the outlet 11f of the holding cylinder 11 is closed by the coin loading surface 13f of the shutter 13). At this time, as shown in FIG. 4, the small arc 15a of the drive plate 15 is located close to the first groove 15p and the second groove 15q, and the first roller 18p and the second roller attached to the driven plate 16. 18q is the deadlock part.

The coin processing device 1 is waiting for coins to be inserted from the insertion slot 2 during operation. When one or more coins are inserted into the coin processing device 1 from the insertion slot 2, the inserted coins are stored in the feeding unit 3. The coins stored in the feeding unit 3 are separated one by one and transported to the insertion path 4 one by one. When foreign matter (including deformed coins having a predetermined value or more) is contained in the coins collectively inserted into the insertion slot 2, the foreign matter is not conveyed to the insertion path 4 and remains in the feeding portion 3. The foreign matter remaining in the feeding portion 3 falls on the reject return chute 8 by opening the openable / closable door provided at the lower portion in a timely manner. If the coins that have been drawn out from the manipulator 3 and tried to pass through the insertion path 4 contain deformed coins or the like that cannot pass through the insertion path 4, the openable door is opened and the deformed coins or the like are taken out. It is good. Deformed coins and the like can typically be taken out manually, but if they cannot be removed successfully, they fall into the reject return chute 8. Foreign matter that has fallen from the payout unit 3 to the reject return chute 8 or deformed coins that have fallen from the insertion path 4 to the reject return chute 8 are then dropped onto the horizontal transport belt 36 and transported by the withdrawal transport unit 35 for withdrawal. It is released into the mouth 39.

The coin that has passed through the insertion path 4 is conveyed to the identification unit 5. When the coin passes through the identification unit 5, the identification unit 5 identifies the type of coin and transmits the identification result to the control device 50. If the coin identified by the identification unit 5 is not considered to be genuine, the control device 50 activates the distribution claw when the coin reaches the distribution unit 6 to reject and return the coin. Drop it to 8. The coins in the reject return chute 8 fall on the horizontal transport belt 36, are transported by the withdrawal transport unit 35, and are discharged to the withdrawal port 39. On the other hand, when the coin identified by the identification unit 5 is considered to be genuine, the coin that has entered the distribution unit 6 is not excluded by the distribution claw and reaches the distribution plate. The coins that have reached the distribution plate pass through the corresponding distribution holes, are counted by the sensor, and enter the temporary holding unit 10 for each type. At this time, since the shutter 13 is in the reference position in the temporary holding portion 10, the coins that have entered the holding cylinder 11 from the inlet 11e are placed on the coin loading surface 13f of the shutter 13 without flowing out from the outlet 11f. , Stacked in the holding cylinder 11.

The coin processing device 1 compares the total amount of inserted coins with the transaction amount by the control device 50, and if change (withdrawal) is not required, the next user keeps the coins stored in the holding cylinder 11. Wait for payment by. On the other hand, when the return operation is performed in the continuous operation of the user who has inserted the coin, the control device 50 operates the motor 14 so that the drive plate 15 in the state shown in FIG. 4 rotates counterclockwise. .. When the drive plate 15 rotates counterclockwise, the first groove 15p captures the first roller 18p of the driven plate 16, and as the drive plate 15 rotates, the first roller 18p penetrates deep into the first groove 15p. Along with this, the driven plate 16 rotates clockwise. When the driven plate 16 rotates clockwise, the shutter 13 connected via the driven shaft 16s of the driven plate 16 moves in synchronization with the driven plate 16 and enters the storage passage 12s. When the shutter 13 completely enters the storage passage 12s, the detection sensor 22b in the position sensor 20 is shielded from light, and the detection sensors 22a and 22c are transparent, 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 holding cylinder 11 is opened, and the holding cylinder 11 and the return passage 12r communicate with each other. As a result, the coins stored in the holding cylinder 11 flow out from the outlet 11f, pass through the return passage 12r, and reach the horizontal transport belt 36. The control device 50 activates the withdrawal transfer unit 35 when the return operation is performed, and the coins that have reached the horizontal transfer belt 36 are discharged to the withdrawal port 39 via the horizontal transfer belt 36.

With the shutter 13 in the reference position and the coins stored in the holding cylinder 11 and waiting for payment by the next user, the operation of the user who deposited the coins is completed and the coin is inserted by the next user. When a coin is inserted into the mouth, it will be as follows. When the operation of the user who has deposited the coin is completed and the coin is inserted into the slot by the next user while waiting for the payment by the next user, the control device 50 is shown in FIG. The motor 14 is operated so that the drive plate 15 in the state shown in is rotated clockwise. When the drive plate 15 rotates clockwise, the second groove 15q captures the second roller 18q of the driven plate 16, and as the drive plate 15 rotates, the second roller 18q penetrates deep into the second groove 15q. Along with this, 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 completely enters the return passage 12r, the detection sensor 22c in the position sensor 20 is shielded from light, and the detection sensors 22a and 22b are transparent, the control device 50 stops the operation of the motor 14. When the shutter 13 enters the return passage 12r, as shown in FIG. 6, the outlet 11f of the holding cylinder 11 is opened, and the holding cylinder 11 and the storage passage 12s are in contact with each other. As a result, the coins stored in the holding cylinder 11 flow out from the outlet 11f, pass through the storage passage 12s, and enter each type of hopper cassette 32 of the storage unit 31.

Going back a little, the control device 50 compares the total amount of the inserted coins with the transaction amount, and if there is a change (withdrawal), the operation proceeds to the withdrawal operation. When the withdrawal operation is to be performed, the control device 50 moves the horizontal transfer belt 36 and the vertical transfer belt 37 of the withdrawal transfer unit 35 to discharge coins for withdrawal from the storage unit 31, and withdraws the coins. Move to 39. When the change is discharged to the withdrawal port 39, the state returns to the state of waiting for the coin to be inserted from the insertion port 2 again, and thereafter, the above-mentioned action is repeated.

When the coins are stored in the holding cylinder 11, there is an abnormality that the coins are stuck in the holding cylinder 11 due to a standing state in which the surface of the coin does not face in the vertical direction or a biting state. It may occur. When an abnormality occurs, the coin processing device 1 is stopped, and maintenance such as clearing the jam of coins is performed. At the time of maintenance, the lever 15r of the drive plate 15 is used to move the drive plate 15, so that the coins remaining in the holding cylinder 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 or the like, the control device 50 moves the shutter 13 to the reference position.

As described above, according to the coin processing apparatus 1 according to the present embodiment, since the drive plate 15 and the driven plate 16 are formed in a plate shape, the temporary holding portion 10 can be downsized. As a result, the coin processing device 1 can be downsized. Further, a linear first groove 15p and a second groove 15q are formed on the drive plate 15, and a first roller 18p and a second roller 18q that enter the grooves are provided on the driven plate 16 to form a link mechanism. Therefore, the manufacturing becomes simple and the manufacturing efficiency can be improved.

Next, with reference to FIG. 8, a modified example of the drive plate and the driven plate will be described. The drive plate 115 and the driven plate 116 according to the modified example are mainly in that the positional relationship between the formation of the groove and the installation of the roller is reversed as compared with the drive plate 15 and the driven plate 16 (see FIG. 4). It's different. That is, the drive plate 115 is provided with the first roller 118p and the second roller 118q. The driven plate 116 is formed with a first groove 116p and a second groove 116q. The drive plate 115 and the driven plate 116 according to this modification are members that replace the drive plate 15 and the driven plate 16 (see FIG. 4) in the temporary holding portion 10 (see FIG. 2) of the coin processing device 1 (see FIG. 1). It functions in cooperation with other members of the temporary holding portion 10 such as the shutter 13 and the holding cylinder 11. Therefore, in the description of the drive plate 115 and the driven plate 116 according to the following modification, when the other member of the temporary holding portion 10 is referred to, the corresponding figure shall be referred to as appropriate.

The drive plate 115 is a plate-shaped member, and its material and thickness can be determined in the same manner as the drive plate 15 (see FIG. 4). The drive plate 115 has a circular outer edge. In the drive plate 115, the shaft 14s of the motor 14 is fixed to the center of the circular shape of the basic shape via the boss 115B. The boss 115B is provided with a convex portion 115t protruding outward in the radial direction in a part of the circumference forming the outer edge. The convex portion 115t is provided on a virtual straight line VD. The virtual straight line VD is any one virtual straight line extending in the radial direction through the drive center 115c. A first roller 118p and a second roller 118q are provided on the surface of the drive plate 115. The first roller 118p and the second roller 118q project from the surface of the drive plate 115 and correspond to the first protrusion and the second protrusion, respectively. The first roller 118p and the second roller 118q are provided at positions where a virtual straight line VD is sandwiched between them. In this modification, the first roller 118p and the second roller 118q are provided at a position where the virtual straight line VD passes through the midpoint of the virtual line segment (not shown) connecting the two at the reference position. However, depending on the design of the movement amount of the shutter 13, the distance from the virtual straight line VD to the first roller 118p and the distance from the virtual straight line VD to the second roller 118q may be different.

The first roller 118p is provided on the first virtual arc VP. The second roller 118q is provided on the second virtual arc VQ. Both the first virtual arc VP and the second virtual arc VQ are centered on the drive center 115c, have a smaller radius than the outer edge of the drive plate 115, and have a larger radius than the distance from the drive center 115c to the tip of the convex portion 115t. , A virtual arc. 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 about an axis perpendicular to the surface of the drive plate 115, respectively. Further, the drive plate 115 is provided with a lever 115r. The lever 115r may be provided at an appropriate position in consideration of the fact that the shutter 13 can be manually operated when it is necessary to move the shutter 13 for maintenance or the like.

The driven plate 116 is a plate-shaped member, and its material and thickness can be determined in the same manner as the driven plate 16 (see FIG. 4). The driven plate 116 has a circular outer edge. The driven plate 116 is connected to the shutter 13 via the driven shaft 16s, similarly to 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 arranged at a position where the driven center 116c exists 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 a virtual straight line VD. The first groove 116p and the second groove 116q are provided at a position where a virtual straight line VD passes between them at a reference position. Each of the first groove 116p and the second groove 116q has one end in the middle of a circular shape having a basic shape and the other end reaching the outer edge. Further, it is preferable that the first groove 116p and the second groove 116q are formed so as to have a width in which the first roller 118p and the second roller 118q can enter the groove and the play is minimized as much as possible. Further, the depths of the first groove 116p and the second groove 116q may be appropriately determined in consideration of the intended movement degree of the driven plate 116.

The portion of the driven plate 116 between the first groove 116p and the second groove 116q is referred to as a groove portion 116t. The driven plate 116 has a positional relationship in which the tip of the grooved portion 116t (the circular outer edge portion of the basic shape in the grooved portion 116t) protrudes toward the drive center 115c from the first virtual arc VP and the second virtual arc VQ. , A part of the driven plate 116 is arranged at a position where it overlaps with the drive plate 115. Further, the driven plate 116 is configured such that the portion of the first groove 116p reaching the circular outer edge of the basic shape is on the first virtual arc VP when it is in the reference position. Similarly, the driven plate 116 is configured such that the portion of the second groove 116q reaching the circular outer edge of the basic shape is on the second virtual arc VQ when in the reference position. Further, when the driven plate 116 is in the reference position, the tip of the groove portion 116t is in contact with the tip of the convex portion 115t of the drive plate 115 in a predetermined area. The predetermined area here can form a deadlock portion that can prevent the shutter 13 from moving due to an external force because the tip of the convex portion 115t is in contact with the tip of the interstitial portion 116t. The area. The convex portion 115t of the drive plate 115 in contact with the tip of the groove portion 116t in a predetermined area corresponds to a surface contact member.

When the drive plate 115 and the driven plate 116 according to the present modification configured as described above are in the reference position and the drive plate 115 rotates counterclockwise, the first roller 118p becomes the first groove 116p. come in. The first roller 118p that has entered the first groove 116p hits the side wall of the interstitial portion 116t (the portion of the interstitial portion 116t that is the boundary portion with the first groove 116p), and then pushes the interstitial portion 116t. The driven plate 116 to which the groove portion 116t is pushed by the first roller 118p rotates clockwise. The shutter 13 moves in synchronization with the clockwise rotation of the driven plate 116 and enters the storage passage 12s. When the shutter 13 completely enters the storage passage 12s, the detection sensor 22b in the position sensor 20 is shielded from light, and the detection sensors 22a and 22c are transparent, the control device 50 stops the counterclockwise rotation of the drive plate 115. do. When the shutter 13 enters the storage passage 12s, the holding cylinder 11 and the return passage 12r communicate with each other. On the other hand, when the drive plate 115 rotates clockwise from the state where the drive plate 115 and the driven plate 116 are in the reference positions, the second roller 118q enters the second groove 116q. The second roller 118q that has entered the second groove 116q hits the side wall of the inter-groove portion 116t and then pushes the inter-groove portion 116t. The driven plate 116 to which the 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 completely enters the return passage 12r, the detection sensor 22c in the position sensor 20 is shielded from light, and the detection sensors 22a and 22b are transparent, the control device 50 stops the clockwise rotation of the drive plate 115. .. When the shutter 13 enters the return passage 12r, the holding cylinder 11 and the storage passage 12s are in contact with each other.

As described above, the drive plate 115 and the driven plate 116 according to the present modification can appropriately operate the temporary holding portion 10 as a substitute for the drive plate 15 and the driven plate 16 (see FIG. 4). Since both the drive plate 115 and the driven plate 116 according to this modification are formed in a plate shape, the temporary holding portion 10 can be downsized, and the coin processing device 1 can be downsized. can. Further, since the drive plate 115 is provided with the first roller 118p and the second roller 118q, and the first groove 116p and the second groove 116q into which these rollers enter are formed in the driven plate 116, the link mechanism is formed. Manufacturing becomes simple and manufacturing efficiency can be improved. Further, since the drive plate 115 is provided with the first roller 118p and the second roller 118q to form no groove, the drive plate 115 can be made smaller than the drive plate 15 (see FIG. 4). .. In the configuration of the drive plate 15 and the driven plate 16 shown in FIG. 4, the distance between the first roller 18p and the second roller 18q in contact with the small arc 15a at the reference position can be relatively large, so that the deadlock It has the advantage of being able to improve performance.

In the above description, it is assumed that the first groove 15p and the second groove 15q of the drive plate 15 shown in FIG. 4 are formed linearly, but depending on the design of the movement mode of the shutter 13, an arc shape or an elliptical arc shape may be formed. It may be formed in a curved shape such as a shape. However, if the first groove 15p and the second groove 15q are formed linearly, there is an advantage that processing becomes easy.

In the above description, it is assumed that the basic shape of the outer edges of the drive plates 15 and 115 is formed in a circular shape, but it is formed in a shape other than a circular shape (for example, a regular polygon such as a rectangle, a hexagon, or an octagon). It may have been done. However, when it is formed in a circular shape, the space required when rotating is minimized, which is preferable. Further, the basic shape of the outer edge of the driven plates 16 and 116 may be a shape other than the circular shape, but it is preferably formed in a circular shape for the same reason as the driving plates 15 and 115.

In the above description, it is assumed that the lever 15r is provided on the opposite side of the small arc 15a with the drive center 15c of the drive plate 15 interposed therebetween, but the operation is not limited to this position and is operated at a position not overlapping the driven plate 16. It suffices if it is provided at a position where it can be. Further, the levers 15r and 115r have an arbitrary configuration, and if the shutter 13 can be moved for maintenance or the like without providing the levers 15r and 115r, the levers 15r and 115r can be omitted.

In the above description, it is assumed that the virtual straight line passing through the drive center 15c and the virtual straight line passing through the driven center 16c are common virtual straight lines VD, but they may be virtual straight lines extending (not matching) at different angles. .. The same applies to the virtual straight line passing through the drive center 115c and the virtual straight line passing through the driven center 116c.
