Description

The present invention relates to an improvement in a coin hopper used in a money handling device such as a vending machine, a money changer, a money dispensing device, and the like, and more specifically, in a coin hopper having a mechanism for dispensing a large number of stored coins one by one. The present invention relates to a coin hopper that can accurately detect whether or not it has been paid.
The present invention also relates to a coin hopper that prevents a payout failure from occurring due to a plurality of coins standing on the rotating member in the coin hopper or clogging in a through hole of the rotating member.

Money handling devices such as vending machines, money changers, and money dispensers are provided with mechanisms for paying coins for change, change money, payout, etc., and a coin hopper is included in such a coin payout mechanism. Usually used. The coin hopper includes, for example, a storage unit that randomly stores a large number of coins of the same type, and a payout unit for paying out coins that are sorted one by one in the lower part of the storage unit. There are various types of such payout units, but if the coins are jammed or stayed in the payout unit, the coin handling device will be inconvenienced when the coins are not paid out at a predetermined timing. Therefore, the passage of coins is usually detected by one or more sensors, and the presence / absence of coin payout completion is determined based on the detection result. If it is determined that the coin has not been paid out based on the detection result from the sensor, the payout operation is repeated, and if the payout is not executed yet, it is visually confirmed that an error such as a coin jam has occurred. The user is informed by a target display, a voice display, etc., and further, the apparatus is stopped, the administrator is notified, and the like.
In particular, in recent devices where coins sorted into denominations enter coin hoppers of the respective denominations for recirculation, it is required to quickly pay out change from each coin hopper. Is strongly demanded to improve on this point because it will betray customers' expectations.

FIG. 8 is an external perspective view showing a schematic configuration of a coin payout detection mechanism in a conventional coin hopper, FIG. 9 is a sectional view showing the internal configuration, and FIG. 10 is a plan view. A coin C is discharged from a discharge port 2 provided on the bottom side wall of the coin storage unit 1 in the lateral direction, and an extrusion arm 3 and a detection unit 4 are disposed outside the discharge port 2. ing. The push-out arm 3 is pivotally supported by a pin 6 provided on a bracket 5 at a base end portion 3a so as to be pivotable in the lateral direction, and a roller 8 is rotatably supported by a pin 7 at the other end portion 3b. . Further, the push-out arm 3 is elastically biased by an elastic member (not shown) in the direction in which the discharge port 2 is closed, and closes the discharge port 2 when no external force is applied. Reference numeral 9 denotes a rotatable guide roller disposed on the opposite side of the pushing arm 3 to guide the coin discharge.
Further, the detection unit 4 is a transmission type for detecting the passage of coins when a coin C to be discharged from the inside of the coin storage unit 1 to the outside through the discharge port 2 is pushed out of the push arm 3 and discharged. It consists of sensors. When handling coins having different outer diameters, the position of the detection unit 4 is fixed while the position of the push-out arm 3 is moved, or the detection unit 4 and the push-out arm 3 are moved together. The detection timing of coins is adjusted.
As shown in FIGS. 9 and 10, the coin hopper is provided at the lower part of the coin storage unit 1, the coin storage unit 1 having an open upper surface, the coin sorting and extruding mechanism 11 disposed at the inner bottom of the coin storage unit 1. A driving unit 12 for driving the pushing mechanism, and a coin dispensing detection unit that detects whether or not the coin pushed out by the pushing mechanism 11 from the coin discharge port 2 provided on the bottom side wall of the coin housing unit 1 has been dispensed. 4 and a control unit (not shown) that determines whether or not coin payout has been completed based on the detection result from the detection mechanism 4.
The extrusion mechanism 11 forms a plurality of through holes 17 having a shape matching the shape of the coins on the disk surface of the disk-shaped rotating member 16 fixed to the output shaft 15 a of the motor 15, one by one in the through hole 17. By rotating the rotating member 16 in the clockwise direction of FIG. 10 with the coins depressed, the coins are guided to the discharge port 2 and pushed out by the push pins 19 provided on the inner bottom surface of the coin housing part 1. It is configured as follows. Since an opening that can communicate with the discharge port 2 is formed on the outer diameter side of each through-hole 17, the coin that hits the push pin 19 is pushed out to the discharge port 2.
Coins randomly stored in the coin storage unit 1 fall into the through holes 17 one by one in the course of rotation of the rotating member 16 at a constant speed in a constant direction, and rotate along the inner bottom surface of the coin storage unit 1. Move to. When the coin in the coin storage unit 1 reaches the front of the discharge port 2, the coin is pushed out along the push pin 19 in the outer diameter direction, and when the coin reaches the discharge port 2, the coin is pushed out from the discharge port 2.
The coin pushed out from the discharge port 2 by the rotation of the rotating member 16 is finally pushed out by the force of the rotating member 16 or the pushing arm 3, but the stop timing of the rotating member 16 after the coin is discharged is detected by the detection unit 4. It is controlled based on the detection signal from.

FIG. 10 is a plan view for explaining the payout operation by the coin hopper. When the detection point by the detection unit 4 is arranged at a position far from the discharge port 2, it is possible to accurately detect the completion of coin payout. Timing is delayed. For this reason, for example, when ten coins are continuously discharged, the stop timing for stopping the rotating member 16 when the payout of the tenth coin is completed is delayed. When the stop timing of the rotating member 16 is delayed, when the rotating member 16 stops, the through hole 17 holding the eleventh coin that is located immediately after the through hole 17 holding the tenth coin has already been formed. The eleventh coin is started to be discharged from the discharge port 2 by rotating to the position that has reached the discharge port 2. In order to prevent such a problem, it is necessary to slow down the rotation speed of the rotating member 16, but this makes it difficult to speed up the payout speed, causing trouble for the user of the money handling apparatus.
In order to eliminate such problems, the detection unit 4 is brought close to the discharge port 2 as shown in FIGS. 11A and 11B, and the detection unit 4 and the pushing arm 3 are supported on the same support member 20. Thus, a configuration has been proposed in which the linear movement is possible in the direction indicated by the arrow. In FIG. 11 (a), the detection point is positioned to the right of the drawing so as to be suitable for the discharge detection of coins having a small diameter, and in FIG. 11 (b), the detection point is arranged to the left of the drawing so as to be suitable for detection of coins having a large diameter. Is located. When the detection unit 4 is arranged at a position close to the discharge port 2 as in this embodiment and is configured to be linearly movable back and forth in the direction of the arrow, when discharging coins having a small outer diameter, FIG. Even if the disk stops while the tenth coin is being discharged as shown in (a), the tenth coin is pushed out by the urging force of the pushing arm 3. On the other hand, when the positions of the detection unit 4 and the pushing arm 3 are shifted outward in order to handle a coin having a large outer diameter as shown in FIG. 11 (b), the tenth coin is in the illustrated state. When the rotating member stops sometimes, a force is applied to the coin from the push-out arm 3 in a direction to push it back into the coin accommodating portion 1, and the coin returns into the through hole 17 of the rotating member or is clogged at the discharge port 2. Such problems occur.

Next, in order to quickly pay out coins, such as change, from the coin hopper of each denomination as described above, it is necessary to prevent slack when paying out from the coin storage portion. The problem here is the phenomenon that a plurality of coins stand on the rotating member in the coin storage part (the coins overlap each other when they rise). 12A and 12B are a longitudinal sectional view and a plan view showing a standing state generated on the rotating member 16 in the coin accommodating portion 1, and an inner wall 1a substantially orthogonal to the upper surface of the rotating member 16. A plurality of coins C are standing up along the line.
When such a standing occurs, it becomes difficult to pay out the coin group, but when this further proceeds and the number of standing coins increases and the coin containing portion 1 is full, the rotating member 16 is reversed. Will not easily collapse.
From this point, the lower end of the long spring material with one end fixed to the upper part of the inner wall of the coin receiving part protrudes toward the upper surface of the rotating member, and prevents the coins that are about to stand up, or protrudes from the upper surface of the rotating member. We are trying to break down coins by taking measures such as stirring. However, such spring materials and protrusions may cause the coin to rise when the rotating member rotates forward or backward. Proposal of a mechanism that can prevent or easily eliminate the generated sag by reversing the rotating member is expected, but has not been realized yet.

Next, another reason for the sluggishness when coins are paid out from the coin accommodating portion and the payout failure occurs is that a plurality of sheets are inserted into the through hole 17 of the rotating member 16 as shown in FIGS. 13 (a) and 13 (b). It can be mentioned that the coins are held in a state of being caught diagonally. That is, ideally, as shown in FIG. 13 (c), the coins C are sequentially stacked while lying on the inner bottom surface 1b of the coin storage portion 1 exposed from the through hole 17, ensuring a smooth payout. This is preferable. However, actually, a plurality of coins obliquely enter the through hole 17 and are positioned downstream in the rotational direction of the rotating member in the payout gap G between the inner peripheral edge of the through hole 17 and the inner bottom surface 1b. When the lower end edge of the coin C1 to be inserted enters, all the coins that have entered the through hole 17 are held in an inclined state. Thus, even if the rotation member 16 is reversed, the state where the coins are packed in the through hole 17 is not easily solved. When this coin jammed state occurs for all the through holes, the coins cannot be dispensed.
More specifically, when the rotating member 16 rotates in the forward rotation direction, the through hole 17 causing the coin clogging as shown in FIG. 13B reaches the discharge port provided on the side wall of the coin accommodating portion. Then, the coin group in the through hole moves up and down a little by coming into contact with the retractable push pin 19 shown in FIG. 10 and the like, but the hooked state of the lower end edge of the coin C1 is not eliminated, so one coin can be removed from the discharge port. It is not discharged. This coin group passes through the push pin 19 by pushing it down or getting over it. Since the inner bottom surface 1b of the coin receiving portion located on the downstream side of the push pin 19 is a flat surface, the lower end edge of the coin C1 remains hooked in the payout gap G even after passing through the push pin 19, together with the rotating member. It will continue to carry around.
As a result, a payout failure and a payout failure occur as described above.

  A problem to be solved by the present invention is that a plurality of coins are clogged in a state where a plurality of coins are held obliquely in a through hole provided in a rotating member rotatably supported on an inner bottom surface of a coin accommodating portion, and the rotating member is reversed. However, it is an object of the present invention to provide a coin hopper that can eliminate the payout failure and the payout failure that occur when the clogging is not solved.

In order to achieve the above-mentioned object, the invention of claim 1 is characterized in that a coin storage portion for storing a plurality of coins and a coin storage portion that is rotatably supported by the inner bottom portion of the coin storage portion and that selects the coins one by one. A rotating member that discharges to the outside from the discharge port formed in the through hole, and the rotating member has a through-hole penetrating in the thickness direction, and penetrates when the inside of the through-hole communicates with the discharge port. In the coin hopper provided with a protrusion on the lower surface of the rotating member for pushing out the coin fitted in the hole on the lower surface of the rotating member, the inner bottom surface of the coin accommodating portion is located at a position substantially downstream of the discharging port and on the lower surface of the rotating member. An arc-shaped push-up ridge is provided at a position avoiding the ridge.
The invention according to claim 2 is characterized in that the upper surface of the push-up protrusion excluding at least its starting end is a flat surface.
According to a third aspect of the present invention, on the upstream side of the starting end of the push-up ridge, an extrusion pin that is supported so as to be able to protrude and retract from a hole provided in the inner bottom surface of the coin accommodating portion and elastically biased in the protruding direction is disposed. It is characterized by.

  Since it comprised as mentioned above, this invention is jammed in the state in which the several coin was hold | maintained diagonally in the through-hole provided in the rotating member rotatably supported by the inner bottom face of the coin accommodating part, and reversely rotates the rotating member. Even if this is done, it is possible to eliminate the payout failure and the payout failure that occur when the clogging is not resolved.

Hereinafter, the present invention will be described in detail with reference to embodiments shown in the drawings.
[Embodiment corresponding to the first problem]
FIG. 1 is an external view of a coin hopper according to the present invention, and FIGS. 2A and 2B are a plan view of the coin hopper according to the present invention and an explanatory diagram of a main part configuration.
The coin hopper includes a cylindrical coin storage unit 30 whose upper surface is open, a coin sorting and extruding mechanism 31 disposed on the inner bottom of the coin storage unit 30, and a drive for driving an extrusion mechanism provided at the lower part of the coin storage unit 30. , A coin discharge port 32 provided on the bottom side wall of the coin storage unit 30, a push-out arm (pushing means) 33 that reliably pushes out coins discharged from the discharge port 32, a push-out mechanism 31 from the discharge port 32, and A coin payout detection unit 34 composed of a transmissive photosensor or the like for detecting whether or not the coin C pushed out by the push-out arm 33 is completed, and the coin payout completion based on the detection result from the detection unit 34. A control unit (not shown) for determining presence or absence.
The push-out mechanism 31 forms a plurality of through holes 37 having a shape matching the shape of the coins on the disk surface of the disk-shaped rotating member 36 fixed to the output shaft 35 a of the motor 35, one by one in the through hole 37. By rotating the rotating member 36 in the clockwise direction in FIG. 2A in a state where the coin is depressed, it is supported so as to be able to protrude and retract from the hole provided in the inner bottom surface of the coin accommodating portion 1 and is urged in the protruding direction. Further, the coin is guided to the discharge port 32 by the push pin 39 and pushed out to the outside. Since an opening that can communicate with the discharge port 32 is formed on the outer diameter side of each through-hole 37, the coin that hits the push pin 39 is pushed out to the discharge port 32. Further, on the bottom surface of the rotating member excluding each through hole 37, an arc-shaped extrusion protrusion 36 a (corresponding to reference numeral 16 a in FIG. 9) is located, and this extrusion protrusion 36 a is a coin in the through hole 37. In order to press the coin, the coin can be pushed out from the discharge port 32 in cooperation with the push pin 39.

The push-out arm 33 rotatably supports a roller 33a made of rubber, resin or the like at its tip, and its base end is pivotally supported on an adjustment base 40, which will be described later, by a shaft 33b. Further, it is urged clockwise in FIG. 2 by an elastic member (not shown).
Coins C randomly stored in the coin storage unit 30 fall into the through holes 37 one by one in the process of the rotation member 36 rotating at a constant speed in a constant direction, and rotate along the inner bottom surface of the coin storage unit 30. Move in the direction. When the coin in the coin storage unit 30 reaches the front of the discharge port 32, the lowermost coin is pushed out along the push pin 39 in the outer diameter direction, and when the coin reaches the discharge port 32, it is pushed out from the discharge port 32 to the outside. It is.
The coin pushed out from the discharge port 32 by the rotation of the rotating member 36 is finally pushed further outward by the force of the rotating member 36 or the pushing arm 33. When discharging a plurality of coins continuously, it is necessary to stop the rotating member 36 immediately after discharging the last coin, but the stop timing of the rotating member is controlled based on a detection signal from the detection unit 34. The
In the present invention, the position of the detection unit 34 is set at the discharge port 32 so that the coin immediately after the last coin discharged is not accidentally discharged from the protruding port due to the delay of the stop timing of the rotating member 36. As close as possible. In other words, the coin C pushed out from the discharge port 32 by the cooperation of the rotating member 36 and the push pin 39 is discharged while pushing away the push arm 33, but when the detecting unit 34 detects the coin C. Then, the positional relationship between the detection unit 34 and the push-out arm 33 is set so that the push-out arm 33 biased by the elastic member always reaches a position where a force for pushing out the coin C can be generated. That is, even if the drive unit of the rotating member 36 is stopped when the detection unit 34 detects the coin C discharged from the discharge port to the outside, the coin is not returned to the inside of the discharge port by the pushing arm 33. It is always configured to be pushed outward. In order to realize such a configuration and coins for all coins having different outer diameters, in the present embodiment, the detection unit 34 and the pushing arm 33 are supported on one adjustment base 40, and The rotation center 41 is configured to coincide with the rotation center 35 a of the rotation member 36.

The adjustment base 40 is, for example, an arc-shaped elongated hole (not shown) provided in the attachment member 42 so that the adjustment base 40 can be fixed at an arbitrary rotation angle with respect to the attachment member 42 projecting to the outer periphery of the coin accommodating portion 30. The adjustment base 40 can be fixed at an arbitrary position with respect to the output shaft 35a by a screw or the like. Therefore, it is easy to adjust the mounting angle of the adjustment base 40 around the output shaft 35a according to the type of coin to be handled and the outer diameter.
As a result of the adjustment base 40 rotating about the output shaft 35a in this way, the adjustment base 40 can be fixed in advance at an optimum angle according to the outer diameter of the coins to be discharged. Each position of the push arm 33 and the detection unit 34 on the base 40 can be fixed after moving along the circumference of a concentric circle centering on the output shaft 35a.
As described above, the positional relationship between the push-out arm 33 and the detection unit 34 and the discharge port 32 is such that the motor 35 of the rotating member 36 is detected when the detection unit 34 detects the coin C discharged from the discharge port to the outside. Even if the operation is stopped, the coin is always pushed out to the outside without being returned to the inside of the discharge port by the push-out arm 33. On the other hand, the push-out arm 33 is adapted to the outer diameter of the coin to be discharged. And the position adjustment of the detection part 34 is performed along the rotation locus | trajectory centering on the output shaft 35a which is the rotation center of the rotation member 36. FIG. For this reason, even if the position of the adjustment base 40 is adjusted in accordance with any coins having different outer diameters, the conditions of the detection unit 34 and the pushing arm 33 are the same, thereby detecting the coins discharged from the discharge port. A force to be pushed out by the push-out arm 33 is applied to the coins discharged at the moment when the part 34 detects. Therefore, regardless of the change in the outer diameter of the coin, even if the rotating member 36 is stopped immediately after the last coin is detected by the detector 34, the last coin is surely paid out. In addition, it is possible to reliably prevent erroneous coin ejection following the last coin ejection.

Next, FIGS. 3 (a) to 3 (f) show the coin hoppers of the present invention each of six denominations of Japanese coins having different outer diameters (in the order of decreasing outer diameter, 1 yen, 50 yen, 5 yen, 100 yen, 10 It is a figure which shows the example which adjusted the angle of the adjustment base 40 so that it might respond | correspond to a circle | round | yen and 500 yen.
If the angle of the adjustment base 40 when adjusted for a 1-yen coin shown in FIG. 3A is used as a reference, the adjustment base 40 becomes 1.3 when adjusted for a 50-yen coin shown in FIG. ° in the counterclockwise direction, 2.6 ° for the 5 yen coin shown in (c), 3.2 ° for the 100 coin shown in (d), (e ) Is adjusted to 4.7 ° in the case of a 10 yen coin, and 8.6 ° in the case of a 500 yen coin shown in (f).
In this way, by adjusting the angle of the adjustment base 40 according to each coin, even if the rotation member 36 is stopped immediately after the last coin is detected by the detection unit 34 regardless of the change in the outer diameter of the coin, The last coin will be paid out reliably. In addition, it is possible to reliably prevent erroneous coin ejection following the last coin ejection.
As described above, according to the present invention, since the rotating member can be stopped immediately when the detecting unit detects the discharged coin, the number of discharged coins and the stop timing of the rotating member can be determined. The determination can be performed almost simultaneously, and the control program in the control unit can be greatly simplified.
Even if the rotating member stops at the moment of coin detection by the detection unit, the coin is surely paid out.
Since the rotating member can be stopped at the moment when the detection unit detects a coin, there is no time loss and the operating rate is increased, while the rotating member can be rotated at high speed, and the coin dispensing speed can be increased. Can do.
In addition, it is possible to adjust to the coins with different outer diameters by simply adjusting the rotation angle of the adjustment base using a screwdriver, etc., and the positional relationship between the detector and the extrusion arm at this time, both The conditions for working together are always constant.

[Embodiment corresponding to second problem]
Next, FIG. 4 is a figure for demonstrating embodiment corresponding to a 2nd subject, and has shown the structure for preventing the standing of a coin.
The coin hopper includes a coin storage unit 30 having an open top surface, a rotating member 36 that is positioned on the inner bottom surface of the coin storage unit 30 and is rotatably supported around a rotation shaft 35a of a motor 35 (not shown), and a coin storage It has a coin discharge port (not shown) opened at a low position on the side wall. Through-holes are formed in the rotating member 36 at a predetermined pitch in the circumferential direction, and coins that are fitted in the through-holes are fed out from the discharge port one by one from the discharge port.
A characteristic configuration of the coin hopper according to this embodiment is that the inner wall of the coin accommodating portion 30 is located above the upper surface of the rotating member 36, and the height position is equal to or greater than the radius dimension (including the radius dimension) of the coin C to be handled. The overhanging rib 50 is provided over the entire circumference. A recess 51 is formed below the overhanging rib 50.
When one coin hopper is configured to be shared by coins of a plurality of denominations, the height position of the rib 50 is a height position equal to or higher than the radius of the largest diameter coin and within the diameter of the smallest diameter coin. Position.
Since the tips of the ribs 50 come into contact with a height position equal to or higher than the center position of the outer side surface of the coins located on the outermost side among the plurality of coins C standing up like this, the vertical inner wall 30a shown in FIG. Is resolved. For this reason, when the rotating member 36 is rotated forward or reversely, the coin group loses its balance and its lower part enters the recess 51 side and falls easily, and the standing coins fall down and become discrete. It becomes easy. For this reason, smooth payout without delay becomes possible.
Further, when a single coin stands on the inner wall while standing, it is likely to occur due to the subsequent coins overlapping with each other, but the rib 50 is provided on the inner wall as in the present invention. As a result, when the rotating member 36 rotates with the first coin standing up in contact with the rib 50, the lower part easily enters the recess 51 and falls down, so that it is possible to prevent standing up. Become.

[Embodiment corresponding to the third problem]
Next, FIG. 5 is a view for explaining an embodiment corresponding to the third problem, and FIG. 5 (a) is a plan view showing a state in which a rotating member is rotatably assembled to the inner bottom surface of the coin accommodating portion. b) is a bottom view of the rotating member, and (c) is a plan view of the inner bottom surface of the coin accommodating portion. 6 is a longitudinal sectional view of the rotating member, FIG. 7 (a) is a clogged state, (b) and (c) are cross-sectional views showing the clogged state, and (d) is a state immediately before reaching the discharge port. It is a figure which shows a state.
As shown in FIGS. 5 (a) and 5 (c), the inner bottom surface 60 of the coin accommodating portion 30 has two holes 60 a at appropriate positions inside the discharge port 32 (for example, a position along the downstream side in the rotation direction of the rotating member 36). The push pin 39 is supported in such a manner that it can be moved in and out, and is urged to protrude upward by an elastic member (not shown). The push pin 39 abuts on a coin that is fitted and moved while lying in the through hole 37 of the rotating member 36 (in a state parallel to the inner bottom surface 60), and discharges the pin located in the outer diameter direction. Extrusion is performed toward the outlet 32, and discharged from the discharge port 32 to the outside through a discharge gap G between the lower surface of the rotating member and the inner bottom surface 60.
A push-up ridge 65 extends in an arc shape on the inner bottom surface 60 immediately downstream of each push pin 39. The push-up ridge 65 is configured to have a position and shape that alternately engage with the arc-shaped extrusion ridge 36a on the back surface of the rotation member 36 shown in FIG. 5B, and prevents the rotation of the rotation member 36. There is nothing. The starting end of the push-up ridge 65, that is, the portion immediately downstream of each push-up pin 39 is an inclined surface 65a that gradually increases in height. Further, the height of the flat upper surface 65b further downstream from the inclined surface 65a is set to close the above-mentioned payout gap G. Accordingly, the rotation of the rotating member 36 causes the inclined surface 65a to relatively enter the gap G at the periphery of the through-hole 37, and further the upper surface 65b to enter, thereby closing the gap G. FIG. As shown in FIG. 7B, the lower end edge of the coin C1 having the lower end edge inserted into the gap G is pushed out of the gap G by the push-up protrusion 65, and further rides on the upper surface 65b as the rotating member 36 rotates. (C)). When the rotating member further rotates in the same direction, other coins that have been clogged in the through hole 37 in a state of overlapping with the coin C1 also sequentially ride on the upper surface 65b, start to collapse, and clogging is eliminated.

When the inner bottom surface 60 of the coin storage portion 30 is in a horizontal posture, of course, even when the opposite other end is inclined downward with the discharge port 32 facing upward, the push-up ridge 65 is close to a half circumference as shown in the figure. By extending to a certain extent, the stacked state of each coin is corrected in the process in which the group of coins that have entered the through hole 37 moves in the circumferential direction along the upper surface 65b of the push-up protrusion 65, and the end of the push-up protrusion 65 is corrected. When a plurality of coins in the through-holes sequentially fall on the inner bottom surface 60 when passing through a portion (for example, the downward inclined surface 65c) and falling on the inner bottom surface 60 where the raised protrusion 65 does not exist Or, it is easy to shift to a sleeping state.
As described above, according to the present invention, when the coin group that has entered the through-hole 37 obliquely and gets on the push-up protrusion 65, the lower end portion is placed in the payout gap G on the downstream side in the rotation direction of the rotating member 36. The coin that has been hooked is released first and other coins that are sequentially adjacent to the upstream side are also pushed up onto the ridge 65, thereby breaking the steeply overlapping state as shown in FIG. Next, when it is rotationally moved to the position of the discharge port 32, as shown in FIG. 7 (d), the lowermost coin is laid down on the inner bottom surface 60 and reliably paid out.
For this reason, the payout failure state due to the fact that a plurality of effects are obliquely clogged in the through hole 37 is immediately eliminated, and normal payout can be realized.
