Description

The present invention relates to Koinho' path for paying by dividing the coin one by one.
For details, it relates to Koinho' path that can prevent erroneous detection of the coin passage sensor by coins paid out to the payout path is pushed back and outputs a plurality of detection signals.
More particularly, it relates to an inexpensive Koinho' path that can prevent erroneous detection of the coin passage sensor by coins paid out to the payout path is pushed back and outputs a plurality of detection signals.
The “coin” used in this specification includes coins as currency, as well as substitute money such as medals and tokens of game machines or similar items.

For example, the coin hopper is built in a game machine, and when a game is won, a predetermined number of medals are paid out at high speed.
As the prior art of the first guide of this type of device, the coin can be moved from the rotating body side to the payout passage side by the anti-reverse means arranged in the coin payout passage according to the applicant's application, An apparatus is known in which the movement of the coin from the throwing-out side to the rotating body side is prevented by the retrograde prevention means so that the counting sensor cannot be brought into the detection state again (for example, Patent Document 1). reference.).

  In order to prevent fraud in a coin hopper according to the application of the present applicant as a second prior art, a rotating disk for feeding out coins, a first guide disposed on the side of the rotating disk, the first guide, and the rotating disk The second guide, the first guide, and the first guide, which are located on the sides of the first guide, can move from the first guide to a standby position having a distance equal to or less than the coin diameter and to a payout position by a coin, and constitute disk passing detection means. 2. A payout passage in which coins passing through the guide move, a payout passage that moves in conjunction with the movement of the second guide, and is located in the payout passage when the second guide is in the payout position and is in the standby position. There is known a coin hopper that has a baffle means for evacuating from the card, and the baffle means stops the fed coins in a payout passage.

JP 2008-276616 (pages 2-4, FIGS. 1-10) JP-A-2006-323530 (paragraph numbers 0016 to 0085, FIGS. 1 to 14)

In the prior art of the first guide, the coins are sorted one by one by the rotation of the rotating body, then guided by the first guide constituting the exit opening, and ejected to the payout passage by the movable second guide.
The coin pushed by the rotating body pushes the blocking roller at the exit opening.
Since the pushed blocking roller moves along the bearing groove in a direction away from the payout passage, the coin moves to the outlet side through the gap of the payout passage defined by the peripheral surface of the prevention roller and is paid out.
When the coin is pushed from the outlet side to the rotating body side, the coin comes into contact with the peripheral surface of the blocking roller.
When the blocking roller is pushed by the coin, the support shaft is guided in the bearing groove, so that the blocking roller further enters the payout passage and prevents the coin from moving toward the rotating body.
Thereby, there existed an expectation which can prevent the fraud which inserts an instrument from a throwing port and misdetects a count sensor.
However, since the peripheral surface of the blocking roller is circular, there is a possibility that it may rarely occur that the insertion of the instrument cannot be blocked by being pushed down by the instrument inserted from the insertion port.

In the second prior art, the second guide is moved while being guided by the first guide when the coin is pushed by the pushing portion of the rotary disk.
Interfering means advances into the payout passage in conjunction with the movement of the second guide.
More specifically, when the second guide is in the payout position, the baffle means is located in the payout passage and prevents the coin from passing through.
When the second guide is in the standby position, the baffle means retreats from the payout passage.
Immediately after the diameter portion of the coin passes between the first guide and the second guide, the coin is vigorously ejected to the payout passage by the urging force against the second guide.
Therefore, when the coin reaches the baffle means, the baffle means retreats from the payout passage in conjunction with the movement of the second guide from the payout position to the standby position, so that the coin is paid out without being blocked by the baffle means. .
Since the coin passage detecting means detects the coin payout by the movement of the second guide and outputs a detection signal, the total number of payout of the discs after the start of payout is counted by counting this detection signal.
When the second guide is intentionally moved to the payout position, the baffle means is located in the payout passage in conjunction with the movement.
As a result, the first coin is pushed out to the payout passage by the pushing portion, and is stopped by the baffle means immediately after the coin center passes on the straight line connecting the first guide and the second guide.
For this reason, the next coin cannot be moved to the payout passage by being obstructed by the first coin.
As a result, the next coin moves along with the rotating disk while being guided by the rear end of the first coin and being pushed by the pushing portion of the rotating disk.
If the coin stopped by the baffle means is paid out, the baffle means is forcibly moved by the coin, so the second guide moves to the payout position.
Thereby, the movement of the second guide is detected directly or indirectly by the coin passage detecting means, thereby detecting the coin payout.
Therefore, there is an advantage that the coins to be paid out can be counted reliably.
In other words, a count signal is output every time a coin passes through the payout passage.
However, in the second prior art, if the dispensing port of the dispensing passage is blocked elastically, since the coins aligned in contact with the peripheral surface in a line of successive reciprocates dispensing passage, one coin Therefore, there is a problem that false detection, that is, so-called “chattering” occurs due to the detection signal being output many times.

A first object of the present invention is to provide a coin hopper that can prevent fraud by inserting an instrument from a coin outlet.
The second object of the present invention is to provide a coin hopper capable of preventing erroneous detection due to elastic closing of a coin outlet.
A third object of the present invention is to provide a coin hopper that is not fraudulent and does not cause chattering at low cost.

In order to achieve this object, the coin hopper of the present invention is configured as follows.
Rotating body for sending out coins that are divided and pushed one by one, a first guide that defines one of the coin payout openings, and a side of the first guide and the rotating body, the move to the dispensing position being moved first guide and a standby position separated by a distance of less than or equal to the diameter of the coin by the coin and a second guide that is resiliently biased toward the standby position, the first And a coin passage detecting device for detecting the coin payout, comprising an action piece interlocking with the movement of the two guides from the standby position to the payout position and a detection means for detecting the movement of the action piece. Then, the coin pushed by the rotating body is guided by the first guide and paid out from the outlet of the payout passage slightly wider than the coin diameter ejected by the second guide, and In the coin hopper, in which the anti-reverse means for allowing the coin to move from the rotating body side toward the pay-out path is provided in the pay-out path, but preventing the reverse movement, the reverse-prevention means is configured to move the coin in the pay-out path. Includes a coin backflow stopper provided in correspondence with a chevron gap between the arc edges of the coins that move forward and backward, and one end of the backflow stopper rotates around a rotation shaft positioned above the payout passage. The other end is made of a rod-like body that is supported on the other end and placed on the bottom surface of the dispensing passage, and the straight lower edge (120U) of the rod-like body is inclined downward toward the outlet, and the other end the tip is configured so as to form a right angle to the bottom surface of the dispensing passage, the rod-shaped body is pushed up by the coin passing through the payout path toward the dispensing port, whereas, the tip Kito to stop the movement of the coins to be retrograde from the outlet, by restricting the movement of the operating member caused by the movement to the dispensing position from the standby position of the second guide by coins the retrograde, the coin passing It is a coin hopper characterized by preventing erroneous detection of coin payout by a detection device .

According to this configuration, the tip of the backflow stopper is disposed in a chevron-shaped gap in a state where coins in the payout passage are aligned, and when the coin goes from the rotating body side to the payout passage side, the coin pushes up the lower edge of the rod-shaped body Can pass through.
Accordingly, the coin is paid out from the throwing port through the payout passage.
The movement of the second guide moved to the payout position by the coin is detected by a sensor, and a signal for counting coins is output.
On the other hand, the movement of the coin from the outlet side to the rotating body side is prevented by the tip of the rod-like body positioned at a right angle to the bottom surface.
As a result, since the coin that has passed through the tip of the backflow stopper cannot return to the rotating body, the second guide is not moved to the payout position by this coin .
In other words, the sensor for counting cannot be brought into the detection state again.
Therefore, the number of coins paid out by the coin hopper and the signal from the count sensor are in a one-to-one relationship, so that it is possible to prevent fraud due to blocking the outlet.
Further, since the coin that has passed through the tip of the rod-like body cannot return to the rotating body side, the count sensor is not moved, and erroneous detection is not caused.

A rotating body for delivery of coins to be pushed one by one sorting coins, a first guide defining a one dispensing opening of the coin, located on a side of the first guide and the rotating member, can be moved from the front Symbol first guide and dispensing position moved by the coin and a standby position away distance less than or equal to the diameter of the coin, and a second guide that is resiliently biased toward the standby position, the has, together with the dispensed from dispensing port slightly wider dispensing passage than the coin diameter the coins to be pushed is flipped by the second guide is guided by the first guide by the rotating body, said dispensing passage in coin hopper wherein Although from the rotary section of the coin allow movement toward the dispensing passage moves in the opposite direction placing the backstop means to prevent the said backstop means, before Ki払 out passage Wherein the backflow stopper coins provided corresponding to the angular gap between the arc edge of the coins back and forth in a case where the coin is continuous you are, the backflow stopper, times one end located above the dispensing passage The other end is formed of a rod-like body that is rotatably supported by the moving shaft and the other end is placed on the bottom surface of the payout passage. The straight lower edge of the rod-like body is inclined downward toward the outlet, and the other tip end is configured to form a right angle with respect to the bottom surface of the dispensing passage, the rod-shaped body is pushed up by the coin passing through the payout path, the tip will stop the movement of the coins to be retrograde from the dispensing port it is Koinho' path characterized by.

Next, the dispensing device 114 will be described with reference to FIGS. 4, 6, and 7. FIG.
The payout device 114 has a function of ejecting the coins 102 that are sorted and sent one by one by the rotating disk 110 one by one.
The payout device 114 includes a payout passage 196 defined by a first guide 186, a second guide 188, an urging means 192, and a passage restriction guide 194.

First, the first guide 186 will be described.
The first guide 186 forms one side wall of the payout passage 196 through which the coin 102 passes, and has a function of guiding the coin 102 to a predetermined position.
The first guide 186 is an angle-shaped plate 198 and is fixed to the upper surface of the bottom portion 144 by a screw 202.
The first guide 186 is configured by a bent portion of the plate 198 formed in a round shape.
The first guide side surface 203 on the guide hole 132 side of the plate 198 is formed in an arc shape having a radius larger than the radius of the rotating disk 110 and constitutes a part of the guide hole 132.
The second guide side surface 206 is a first side wall 199 and constitutes one side surface of the payout passage 196.
In the present embodiment, the first guide 186 is the plate 198 , but can be changed to a roller rotatably attached to a fixed shaft.

Next, the second guide 188 will be described.
The second guide 188 has a function of flipping out the coin 102 sandwiched between the first guide 186 and the second guide 188.
The second guide 188 is disposed on the side of the rotary disk 110 and the first guide 186, and constitutes one side wall of the payout passage 196.

The second guide 188 is a roller 220 that is rotatably attached to a support shaft 218 that is fixed to one end of a swinging lever 216 that is pivotally attached to a fixed shaft 214 that is fixed to the back side of the hopper base 106. It is.

The urging means 192 has a function of bringing the second guide 188 closer to the first guide 186 elastically.
Normally, the swinging lever 216 is locked by an elastic locking portion 228 fixed to the back surface of the hopper base, so that the locked portion 226 formed integrally is locked with respect to the first guide 186. It is stopped at intervals smaller than the diameter and is stationary at the standby position SB.
By using the elastic locking portion 228, receiving the swinging lever 216 has an advantage that the hitting sound can be reduced and the swinging lever 216 can be prevented from bouncing back.
The second guide 188 protrudes to the front side of the hopper base 106 through an arc-shaped long hole 217 formed in the hopper base 106.

After the diameter portion of the coin 102 moves between the first guide 186 and the second guide 188, the center of the coin 102 is positioned on a straight line connecting them, and the second guide 188 is moved to the payout position DP, The coin 102 is ejected by the resilience of the biasing means 192.
The second guide 188 is pivoted by the swing lever 216, but can be changed so as to approach and separate from the first guide 186 by linear motion.
Further, the urging means 192 can be changed to a device having a similar function such as an electromagnetic actuator and an air actuator in addition to the spring.
Similarly to the first guide 186, the second guide 188 can be a non-rotating guide.

Next, the passage restriction guide 194 will be described with reference to FIG.
The passage restriction guide 194 has a function of defining a bottom surface and an upper wall of the discharge passage 196 on the side of the outlet 197 and the outlet.
The passage restriction guide 194 includes a discharge outlet defining body 184, a lower restriction guide 190U, an upper restriction guide 190A, and a plate 198 extending laterally from the discharge outlet defining body 184.
A laterally slit-like passage 204 is formed in the discharge port defining body 184 and is disposed on the extension of the discharge passage 196.
The passage 204 is a slit-like passage formed by the lower wall 204U, the upper wall 204A, the first guide side wall 204S1, and the second guide side wall 204S2, which is slightly larger than the thickness and diameter of the coin 102.
The first guide sidewall 204S1 is constituted by a second guide side 206 approximately.
Accordingly, the payout passage 196 is integrated with the passage 204 to form the payout passage 196.
A flat lower regulation guide 190U protrudes flush with the lower wall 204U of the passage 204.
The upper surface of the lower regulation guide 190U is fixed to the support portion 124 flush with the bottom portion 144.
The upper restriction guide 190A is detachably fixed above the lower restriction guide 190U by a screw (not shown) so that the lower surface thereof is flush with the upper wall 204A.
Accordingly, the payout passage 196 is also defined by the upper restriction guide 190A.
In other words, the payout passage 196 is formed as a tunnel having a predetermined length with a rectangular cross section by the payout passage bottom 195, the first guide 186, the second guide 188, and the passage restriction guide 194.

  The coins 102 paid out by the payout device 114 are paid out from the outlet 197 of the payout passage 196 located on the left side surface of the hopper base 106.

Next, the coin passage detection device 116 will be described with reference to FIG.
The coin passage detection device 116 has a function of detecting a movement of the second guide 188 by the coin 102 directly or indirectly and outputting a detection signal.
The coin passage detection device 116 of this embodiment includes a second guide 188, a swing lever 216 that supports the second guide 188, an action piece 230 that moves in conjunction with the swing lever 216, and a detection means 232 for the action piece 230. Is included.

The action piece 230 is a detected portion 238 that is formed on the tip of an arm 236 formed integrally with the swinging lever 216 and located on an arc centered on the fixed shaft 214.
As shown in FIG. 6, the arm 236 is provided in a positional relationship with a predetermined length in the normal direction of the fixed shaft 214 located on the back surface side of the hopper base 106 and perpendicular to the swing lever 216.

The detection means 232 has a function of outputting an on / off electrical detection signal DS when the detected part 238 is detected.
The detection means 232 of the embodiment includes a sensor 244 and a detection signal output means 246.
As shown in FIG. 8, the sensor 244 is a transmissive photoelectric sensor having a light projecting unit 250 disposed on one side of a portal-shaped column 248 and a light receiving unit 252 disposed on the other column facing the light projecting unit 250. It is.
The sensor 244 is fixed to the hopper base 106 via a bracket 256 on the back side thereof.

Accordingly, in the present embodiment, the sensor 244 is located below the hopper base 106 surrounded by the support portion 124, and therefore it is extremely difficult to illegally access the sensor 244 from the outside.
When the second guide 188 is moved to the payout position DP (see FIG. 12) by the coin 102, the detected part 238 blocks the projection light from the light projecting part 250 to the light receiving part 252.
By this interruption, the output of the sensor 244 changes from “H” to “L”.
When the second guide 188 is positioned from the payout position DP to the standby position SB, the detected part 238 is disengaged from between the light projecting part 250 and the light receiving part 252, so the output of the photoelectric sensor 244 changes from “L” to “H”. Become.

The detection signal output means 246 outputs the detection signal DS when the output of the sensor 244 changes from “L” to “H”.
By counting this detection signal DS, the number of coins 102 paid out can be known.
Therefore, the detection means 232 can be changed to another method having the same function, and the sensor 244 can be changed to another sensor such as a reflective photoelectric sensor or a metal sensor.

Further, the coin passage detection device 116 can be configured by directly detecting the movement of the swing lever 216 or the roller 220.
The detection means 232 can be substituted by detecting the rising signal of the sensor 244 without providing the detection signal output means 246.

Next, the fraud prevention device 118 will be described with reference to FIGS.
The fraud prevention device 118 has a function of preventing the coin passing detection device 116 from paying out only the coin 102 without outputting the detection signal DS when the second guide 188 is moved from the outside to the payout position DP.
The fraud prevention device 118 is a baffle means 260 that moves in the payout passage 196 downstream of the payout device 114 in conjunction with the second guide 188.
In this embodiment, the baffle means 260 is a baffle member 266 attached to a second support shaft 264 fixed to the end of a second lever 262 that extends on the opposite side of the fixed shaft 214 with respect to the swinging lever 216.

The baffle member 266 is preferably a roller 268 rotatably attached to the second support shaft 264 in terms of durability, but can be changed to a pole-shaped fixed baffle piece.
The baffle member 266 passes through an arc-shaped elongated hole 270 formed in the passage restriction guide 194 and protrudes into the discharge passage 196.
When the second guide 188 is located at the standby position SB, the baffle member 266 is located at the release position FP where the distance between the first guide 186 and the second guide side face 206 is more than the diameter of the coin 102.

At this time, the action piece 230 is at a position where the projection light from the light projecting unit 250 is blocked as shown in FIG.
When the second guide 188 is positioned at the payout position DP, the baffle member 266 moves to the baffle position OP where the distance between the first guide 186 and the second guide side face 206 is equal to or smaller than the diameter of the coin 102 (see FIG. 12).
Therefore, when the coin 102 passes between the baffle member 266 and the second guide side surface 206, the baffle member 266 is moved to the release position FP.

When the baffle member 266 is moved to the release position FP, the second guide 188 moves to the standby position SB, so that the action piece 230 moves from the detection position to the non-detection position.
Therefore, since the output of the detection means 232 changes from “L” to “H”, the detection signal output means 246 outputs the detection signal DS.
In other words, when the coin 102 is paid out from the outlet 197, the baffle member 266 is moved from the baffle position OP to the release position FP, and thus the detection signal DS is output from the detection signal output means 246.

Next, the backflow stopper 120 serving as backflow prevention means will be described with reference to FIGS.
The backflow stopper 120 has a function of preventing an overlap detection signal from being output by the coin passage detection device 116 when the coin 102 that has passed through the payout device 114 moves back to move the second guide 188.
In other words, the coin 102 that has passed through the payout device 114 has a function of preventing it from coming into contact with the second guide 188.

The backflow stopper 120 of this embodiment is a straight rod-like body, specifically a prismatic shape, and is integrally formed with a rotating shaft 278 whose one end is rotatably supported by the upper regulating guide 190A. .
Specifically, a rotation shaft 278 is disposed above the discharge passage 196 on the rotating disk 110 side in parallel with the discharge passage bottom 195, and one end portion of the backflow stopper 120 is integrally formed on the rotation shaft 278. .
A slit hole 280 is formed in the upper regulating guide 190A along the payout passage 196, and the backflow stopper 120 is inserted so as to be movable in the vertical direction.
In other words, the backflow stopper 120 can rotate while being guided by the side edge of the slit hole 280 in the slit hole 280.
The backflow stopper 120 is located at a standby position SP where the lower edge of the tip 120T abuts against the discharge passage bottom 195 (the lower wall 204U of the outlet defining member 184) and stops at a self moment.
At the standby position SP, the straight lower edge 120U of the backflow stopper 120 is inclined forward and downward from the rotating disk 110 side toward the outlet 197 side.

The end surface of the tip 120T of the backflow stopper 120 is formed so as to be substantially perpendicular to the discharge passage bottom 195 ( lower wall 204U).
Thereby, the coin 102 moving from the rotating disk 110 side toward the outlet 197 can push up the straight lower edge 120U of the backflow stopper 120 and pass therebelow while contacting the lower edge of the tip 120T.
The tip 120T of the backflow stopper 120 has a chevron gap 178 formed between the arcuate peripheral surfaces in a state where the coins 102 are in contact with the peripheral surfaces and aligned in a line in the payout passage 196 (see FIG. 5B). Is set to be located at
In other words, the tip 120T of the backflow stopper 120 is disposed in the chevron gap 178 between the arc edges when the coins 102 are arranged in a line in the payout passage 196.

The position of the tip 120T of the backflow stopper 120 is set such that the distance connecting the tip 120T and the baffle member 266 when the second guide 188 is located at the standby position SP is smaller than the diameter of the coin 102.
With this configuration, when the coin 102 is pushed back from the outlet 197 to the rotating disk 110 side, the coin 102 to be pushed back is prevented from moving by the tip 120T of the backflow stopper and hardly returned.
As a result, the second guide 188 is not moved by the coin 102 pushed back.

The backflow stopper 120 may be a rotating force based on only the self-moment, but the moving speed of the coin 102 is increased, and as a result, when the tip 120T is always separated from the payout passage bottom 195 (204U), in order to strengthen the return force of the backflow stopper 120 Spring force can be added.
As shown in FIG. 11 (A), the backflow stopper 120, which is a rod-shaped body, is pushed up by the coin 102 passing through the payout passage 196, and the tip 120T stops the movement of the coin going backward from the outlet 197.

Next, the operation of the embodiment will be described.
When a payout instruction signal for the coin 102 is received, a motor (not shown) rotates, and the rotary disk 110 is rotated clockwise in FIG. 3 via a speed reducer and a rotary shaft 146 (not shown).
Due to the rotation of the rotating disk 110, the coin 102 falls into the through hole 160, is pushed by the first pushing portion 168, and its lower surface slides on the bottom portion 144 of the guide hole 132, and the circumferential surface is guided to the circumferential wall 150. The first regulation body 180 is reached.

The coin 102 is guided in the circumferential direction of the guide hole 132 by the first restricting body 180 .
At this time, force is applied to the first restricting body 180 from the lateral direction, but since the elastic force of the urging means 192 is greater, the first restricting body 180 is kept substantially perpendicular to the bottom portion 144.

As the coin 102 moves in the circumferential direction with respect to the rotating disk 110, the coin 102 reaches between the first guide 186 and the second guide 188 (see FIG. 12).
Since the coin 102 is pushed further circumferentially by the first pushing portion 168 and then by the second pushing portion 170, and the first guide 186 is fixed, the second guide 188 is moved from the position shown in FIG. Moves diagonally upward to the right.

As a result, the swing lever 216 is rotated counterclockwise in FIG.
When the second guide 188 is moved by the coin 102, the action piece 230 that pivots integrally with the swinging lever 216 blocks the projection light from the light projecting unit 250 of the sensor 244, and thus is shown in FIG. The output changes from “H” to “L”.
Further, the baffle member 266 is moved from the release position FP to the baffle position OP via the second lever 262 (FIG. 12).

The coin 102 is flipped through the second guide 188 by the urging means 192 immediately after its center passes on the straight line connecting the first guide 186 and the second guide 188, and passes through the payout passage 196 to be the outlet 197. Will be paid out.
As a result, the second guide 188 returns to the standby position SB, so that the baffle member 266 returns to the release position FP in conjunction with it.

Therefore, the coin 102 ejected by the second guide 188 is paid out from the outlet 197 without being blocked by the baffle member 266.
In addition, since the action piece 230 moves out of the detection area of the sensor 244 in conjunction with the return movement of the second guide 188 to the standby position SB, the projection light from the light projecting unit 250 is received by the light receiving unit 252. (FIG. 11 (B)).

As a result, the output of the sensor 244 changes from “L” to “H” as shown in FIG.
Based on the output change from “L” to “H”, the detection signal output means 246 outputs the detection signal DS (FIG. 13 (B)).
Therefore, by counting this detection signal DS, the number of coins 102 paid out from the outlet 197 can be counted.

Next, a case where the second guide 188 is forcibly moved to the payout position DP by a rod-like body inserted from the outlet 197 will be described.
In this case, the baffle member 266 is held at the baffle position OP in conjunction with the movement of the second guide 188.
As a result, as shown in FIG. 5B, the coin 102 guided to the first restrictor 180 is prevented from advancing by the baffle member 266 in the payout passage 196, and the rear end of the coin 102 is generally located in the guide hole 132. Stops while positioned on the outer periphery.
Due to the continued rotation of the rotary disk 110, the succeeding coin 102 is guided by the rear end of the coin 102 that has been prevented from proceeding, and pushes the first restrictor 180 in the lateral direction.

By this pushing, the first restricting body 180 receives a large force in the direction D in plan view as shown in FIG.
As a result, the first regulating body 180 sinks below the bottom 144 by the retracting device (not shown) and retracts from the movement path 182 .
That is, the head of the first restricting body 180 moves into the first through hole 177 .

In other words, the first restricting body 180 leaves the movement path 182 of the coin 102.
As a result, the coin 102 is not prevented from moving by the first restricting body 180 and is rotated together with the rotating disk 110.
Therefore, there is an advantage that an overload is not applied to the drive motor (not shown) of the rotary disk 110.

Further, since the second guide 188 is continuously held at the payout position DP, the action piece 230 is continuously detected by the sensor 244.
That is, as shown in FIG. 13C, since the output of the sensor 244 remains “L”, the detection signal DS is not output from the detection signal output means 246.
In other words, when the coin 102 is blocked from being paid out by the baffle member 266, the detection signal DS is not output and the coin 102 is not counted.

When the continuous holding of the second guide 188 is released, the coin 102 that has been prevented from moving by the baffle member 266 is pushed by the second guide 188 trying to return to the standby position SB by the urging force of the urging means 192.
Since the baffle member 266 moves to the release position FP in conjunction with the movement of the second guide 188 to the standby position SB, the coin 102 is paid out from the outlet 197.
At this time, the action piece 230 does not block the projection light from the light projecting unit 250 of the sensor 244.

For this reason, as indicated by a symbol E in FIG. 13C, the output of the sensor 244 changes from “L” to “H”.
Thereby, as shown in FIG. 13D, the detection signal output means 246 outputs the detection signal DS, and this detection signal DS is used for counting the number of coins 102 to be paid out.
Therefore, when the coin 102 is paid out from the outlet 197, the detection signal DS is always output, so there is no coin 102 to be paid out without being counted.
In other words, it is possible to prevent the uncounted payout of the coin 102.

Next, with reference to FIG. 5 (B), an operation when the coins 102 paid out are pushed back from the outlet 197 side will be described.
When the coin 102 passes below the tip 120T of the backflow stopper 120 and a part of the coin 102 is exposed from the outlet 197, the next coin C is ejected by the second guide 188.
Therefore, the coin 102 pushed back pushes the coin 102 ejected by the payout device 114 back to the rotating disk 110 side.
However, as shown in FIG. 5 (B), the coin 102 pushed back by the tip 120T of the backflow stopper 120 is prevented from advancing, so that the coin 102 tends to advance into the gap between the backflow stopper 120 and the baffle member 266 .
At this time, the flipped coin 102 is slightly moved toward the second guide 188 by the coin 102 pushed back.
As a result, the first guide 186 and the second guide 188 move so as to be widened by the coin 102.
On the other hand, the baffle members 266 traveling in the dispensing passage 196 in the opposite phase is moved a gap between the backflow stopper 120 in the narrow Mel direction.
Thereby, the coin 102 to be pushed back is stopped by the baffle member 266.
Therefore, since the second guide 188 does not move when the force to push back and the force to push in balance, the detection means 232 is set so as not to detect the action piece 258 at this balance position as shown in FIG. Therefore, chattering can also be prevented.
