Description

The present invention relates to a coin hopper for sorting and paying out coins one by one.
Furthermore, the present invention relates to a coin hopper that can be easily changed to adapt to different coin sizes.
More specifically, the present invention relates to a coin hopper capable of paying out two types of coins having different diameters without requiring any change of coins.
In this specification, the coin includes not only a coin as a currency but also a token for a game.
The first diameter coin means a small diameter coin, and the second diameter coin means a large diameter coin.

The most popular as a coin hopper is a type in which coins are separated one by one by a rotating disk having a plurality of through holes and then ejected.
In this type of coin hopper, it is necessary to satisfy the coin sorting function, the ejecting function, and the counting function.
Usually, the coin sorting function is satisfied by using a through-hole rotating disk suitable for the diameter of each coin type, and the ejecting function and the counting function are satisfied by making adjustments suitable for the coin diameter. .
In recent years, there is a demand for a coin hopper that does not use such a component corresponding to the coin diameter and does not require adjustment according to the diameter, in other words, a size full hopper.
This is because a replacement coin hopper for each coin diameter is not required, so that an error in replacement can be eliminated, and the number of storage and storage location can be reduced.
In the coin hopper using a rotating disk, in order to make the coin size free, the sorting function and the ejecting function can be satisfied by adjusting the diameter of the through hole to the maximum diameter coin.

On the other hand, the coin counting function is achieved by the following two methods.
The first method is a method in which paid-out coins are directly detected by a metal sensor or photoelectric sensor in a non-contact manner (see, for example, Patent Document 1).
The second method is a method that directly or indirectly detects the movement of the guide that elastically contacts the coin (see, for example, Patent Document 2).
The first method can be detected without being affected by the diameter of the coin, but has a problem that the sensor is easily fraudulent because the sensor is arranged near the coin exit.
The second method is difficult to be fraudulent because the sensor is arranged at a position far from the coin exit, but there is a problem that the sensor position must be adjusted according to the coin diameter in order to detect movement by the coin.
Considering fraud countermeasures, it is a good idea to adopt the second method.
In the method of directly or indirectly detecting the movement of a coin guide that is moved by a coin, when detecting coins with different diameters with a single counting device, the position of the sensor is usually the position of the sensor because the movement position of the coin guide varies depending on the coin diameter. There is a problem that needs to be adjusted.

JP-A-11-353511 (FIGS. 1-4, pages 2-4) JP 2000-222611 (FIGS. 1-4, paragraph numbers 0006 to 0031)

This problem will be described in detail with reference to FIG.
The lower part of the rotating disk 12 in which a plurality of circular through holes 10 are formed at equal intervals is rotatably disposed in a circular bottomed pan-shaped guide hole 14.
Pushing portions 16 are formed on the back surface of the rotating disk 12 corresponding to the through holes 10.
A first guide 18 is fixed to one side of the opening 16 of the guide hole 14, and a second guide 22 is arranged on the other side so as to be elastically movable between a standby position and a protruding position.
The second guide 22 is rotatably attached to one end of a lever 26 that is swingably supported by the fixed shaft 24, and is urged to approach the first guide 18 by an elastic body 28 that is hooked on the lever 26. .
Specifically, the second guide 22 stands still in a standby position where the distance from the first guide 18 is smaller than the diameter of the coin, and is moved to the ejecting position by the coin guided by the first guide 18, Immediately after the diameter portion passes between the first guide 18 and the second guide 22, it is ejected by the elastic force of the elastic body 28.
By detecting the movement of the action piece 32 of the lever 26 by the non-contact sensor 34, a counting signal is obtained.

In the case of the large-diameter coin LC, the action piece 32 is moved to the position indicated by the solid line, so that the sensor 34 is adjusted to the optimum position.
However, in the case of the small-diameter coin SC, the action piece 32 moves to the chain line position, so that the passage timing of the sensor 34 and the like change. In order to solve this, there is a problem that the sensor 34 must be adjusted to the optimum position.
In order to solve this problem, a counting device incorporating a program for automatically adjusting the passage timing change can be adopted. However, since an arithmetic processing device is required, it is expensive and cannot be adopted.

A first object of the present invention is to provide a coin hopper that does not require adjustment of the position or the like of a coin sensor when changed to a coin having a different diameter.

In other words, the lower end portion 152 extends obliquely upward, the upper end portion is formed with a storage portion 154 that expands in a square shape, and the upper end is an upper opening 156 for inserting coins 102.
The upper part of the rotating disk 110 is disposed in the bottom hole in the cylinder at the lower end 152.
The storage portion 154 and the lower end portion 152 of the storage bowl 108 are connected by an inclined wall, and the coin 102 that has ridden thereon naturally slides down due to gravity and falls onto the rotating disk 110 below.

A restricting plate 153 that is inclined downward toward the rotating disk 110 is disposed above the rotating disk 110 to restrict the amount of coins 102 that can be positioned on the rotating disk 110.
The coin 102 on the regulating plate 153 naturally slides on the rotating disk 110 due to its inclination.
Further, the restricting plate 153 is provided so as to be rotatable about one end as a fulcrum. When a coin jam occurs, the restricting plate 153 is rotated upward so that the jam clearing operation can be easily performed.
The retaining bowl 108 can be easily attached to the hopper base 106 by engaging the first mounting portions 134A and 134B and the second mounting portions 136A and 136B with locking portions (not shown) formed in the lower portion of the storage bowl 108. It can be installed and removed.

Next, the rotating disk 110 will be described with reference to FIG. 3, FIG. 6, and FIG.
The rotating disk 110 has a function of sorting the coins 102 held in a loosely stacked state in the holding bowl 108 one by one and transporting them to the ejecting device 114.

The rotary disk 110 is rotationally driven via a speed reducer 157 by an electric motor 155 (see FIG. 5).
On the rotating disk 110, circular through holes 158 are formed at equal intervals on a circle with a predetermined radius centered on the rotation axis, and a downward cone-shaped introduction portion 160 is formed on the upper surface side of the through holes 158. ing.
Further, a conical shape is formed at the central portion, and a central convex portion 162 for attaching the rotating shaft 146 and stirring the coin 102 is formed.
The rotating disk 110 has a lower portion disposed in the guide hole 132, a circumferential surface thereof with respect to the circumferential wall 150, and an upper portion disposed in the bottom hole of the lower end portion 152 of the storage bowl 108 with a slight gap.

On the lower surface of the rib 164 that defines the through-hole 158 that is the back surface 161 of the rotating disk 110, a first push-out portion 166 and a second push-out portion 168 for pushing out the coin 102 are directed downward relative to the through-hole 158, respectively. Protrusions are formed.
First extruding surface 166A and second extruding surface 168A (see FIG. 7) of first extruding portion 166 and second extruding portion 168 are located on an involute curve extending from the central portion of rotating disk 110.
Between the first extruding part 166 and the second extruding part 168, a second guide for guiding the first groove 170 and the second diameter coin 102A for passing through a regulating body 112 constituting a circumferential guide device 112 described later. A second groove 172 for the body 229 is formed.

A ring-shaped coin receiving plate 174 is fixed coaxially with the rotation axis of the rotary disk 110 at the leading ends (lower ends) of the first pushing portion 166 and the second pushing portion 168.
More specifically, the back surface 161 of the rotating disk 110 and the top surface 178 of the coin receiving plate 174 are parallel to each other, and are set at an interval less than the equivalent of two coins 102 in thickness.
The coin receiving plate 174 has an outer diameter that is slightly smaller than the outer diameter of the rotating disk 110 and an inner diameter that is positioned slightly outside the center of the through hole 158.
The coin receiving plate 174 is disposed so as to rotate in a ring groove 176 formed concentrically with the rotation shaft 146 on the bottom surface 144 of the guide hole 132.
At this time, the upper surface 178 of the coin receiving plate 174 is disposed in the same plane as the bottom surface 144 of the guide hole 132.
With this configuration, the coin 102 that has fallen into the through hole 158 is supported by the coin receiving plate 174 and the bottom surface 144 and is pushed by the first pushing portion 166 and the second pushing portion 168, so that it slides with respect to the bottom surface 144. To do.

When the rotating disk 110 rotates, the coin 102 placed thereon is agitated by the through hole 158, the central convex portion 162 and the like, the posture is changed, and falls into the through hole 158.
The dropped coin 102 is supported by the upper surface 178 of the coin receiving plate 174 on the outer peripheral side of the lower surface and the bottom surface 144 of the inner peripheral side.
Then, the rotary disk 110 is rotated by the first extruding surface 166A and the second extruding surface 168A along with the rotating disk 110 by the rotation of the rotating disk 110.
At this time, the inner peripheral lower surface of the coin 102 slides on the bottom surface 144, and the peripheral surface is guided by the peripheral wall 150. However, the contact pressure on the peripheral wall 150 is mostly based on centrifugal force, so it is not a large contact pressure. .
In the follow-up process, the coin 102 whose rotation is prevented by the circumferential guide device 112 is guided in the circumferential direction of the rotary disk 110, and finally pushed out of the rotation area of the second pushing surface 168A.

Next, the circumferential guide device 112 will be described with reference to FIGS.
The circumferential guide device 112 has a function of guiding the coin 102 pushed by the first pushing portion 166 and the second pushing portion 168 in the circumferential direction of the rotating disk 110 and guiding it to the outlet opening 138.

Specifically, a cylindrical pin-shaped restricting body 180 extending through the hopper base 106 from the lower side to the upper side and extending toward the rotating disk 110 is disposed.
In other words, the regulating body 180 protrudes in the movement path 182 of the coin 102.

The restricting body 180 is attached to a retracting device 184 attached to the attaching portion 142 on the back surface of the hopper base 106.
In the retracting device 184, a regulating body 180 is fixed to the other end of the leaf spring 186 whose one end is fixed to the mounting portion 142 by a fixing pin 173.
As a result, the coin 102 pushed by the first pushing portion 166 and the second pushing portion 168 is prevented from moving by the restricting body 180 and thus guided to the outlet opening 138 side.
A slope is formed at the opposite end of the regulating body 180, and when the rotating disk 110 is reversed, the coin 102 rides on the slope and can be reversed.
In addition, when the coin 102 naturally moves to the outlet opening 138 without using the regulating body 180, it is not necessary to arrange them.
In other words, when the diameter of the rotating disk 110 is large and the coin 102 can be guided in the circumferential direction of the rotating disk 110 by the first pushing portion 166 and the second pushing portion 168, the regulating body 180 does not need to be arranged.
When the regulating body 180 receives a predetermined lateral force from the coin 102, the leaf spring 186 is elastically deformed so that the regulating body 180 can move downward below the bottom surface 144, and the coin 102 moves over it. It can be moved with the rotating disk 110.

Next, the outlet opening 138 will be described with reference to FIG.
The outlet opening 138 is a rectangular opening in which the peripheral wall 150 of the guide hole 132 on the side of the circumferential guide device 112 is cut out over a predetermined length.
In the first embodiment, since the exit of the coin 102 is defined by the first guide 188 and the second guide 190, the exit opening 138 is between them.
The length of the outlet opening 138 (the circumferential length of the guide hole 132) is sufficient for the coin 102 to pass through.

Next, the outlet passage 116 will be described with reference to FIG.
The exit passage 116 has a function of guiding the coin 102 ejected by the ejecting device 114.
The outlet passage 116 is a thin plate-like passage that extends in the circumferential direction of the rotating disk 110 continuously to the outlet opening 138.
The exit passage 116 is a part of a plate-like body formed at the lower end of the retaining bowl 108 that covers the concave groove 191 formed in the hopper base 106, the first guide 188, the second guide 190, and the upper release surface of the concave groove 191. It is defined by an exit passage defining guide 193 and extends in the circumferential direction of the rotating disk 110.
The bottom surface 196 of the concave groove 191 is disposed in the same plane as the bottom surface 144, and the lower surface of the coin 102 pushed out by the second pushing portion 168 is guided.
The outlet passage defining device 120 is constituted by the hopper base 106 and the outlet passage defining guide 193 in the first embodiment.
However, as long as the structure delimits the passage of the coin 102, other configurations can be adopted.

Next, the ejecting device 114 will be described with reference to FIGS.
The ejecting device 114 has a function of ejecting the coins 102 that are separated and sent one by one by the rotating disk 110 one by one.
The ejecting device 114 includes a first guide 188, a second guide 190, and an urging means 216.

Next, the first guide 188 will be described with reference to FIG. 3, FIG. 4, FIG. 8, and FIG.
The first guide 188 of the present invention has a function of making the movement amount of the second guide 190 the same regardless of whether the first diameter coin 102A or the second diameter coin 102B is paid out.
The first guide 188 is a stepped plate-like body, and is disposed in a mounting hole 198 formed adjacent to the guide hole 132 of the hopper base 106 so as to be movable in the vertical direction perpendicular to the hopper base 106. .
In other words, the first guide 188 is disposed at one end of the outlet opening 138 so as to be movable in the vertical direction with respect to the hopper base 106.

The first guide 188 of the present invention has a stepped shape in a side view in which an upper step portion 194 is superimposed on a lower step portion 192.
The lower step portion 192 includes at least a linear first side surface 192A constituting the peripheral wall of the guide hole 132 and an arc-shaped first diameter guide portion 192B corresponding to the first diameter coin 102A continuous to the first side surface 192A. .
The upper stage portion 194 has a second side surface 194A that is at least outward from the first side surface 192A and parallel to the first side surface 192A when the rotation shaft 146 is used as a reference, and a second side surface 194A that is continuous with the second side surface 194A. An arc-shaped second diameter guide portion 194B corresponding to the diameter coin 102B is included.
The first diameter guide portion 192B is an arc surface that forms an arc of about 90 degrees with respect to the first side surface 192A, is adjacent to the bottom surface 196 of the recessed groove 191, and is positioned slightly outward from the peripheral wall 150 of the guide hole 132.

The upper end of the first side surface 192A of the lower step portion 192 of the first guide 188 and the lower end of the second side surface 194A of the upper step portion 194 are surface-connected to form a driven portion 199.
The driven part 199 is a rectangular L-shaped plane that connects the upper end of the first side surface 192A and the lower end of the second side surface 194A with a predetermined width, and as shown in FIG. 11 (B), the second diameter coin 102B Has a width of about one fifth to one sixth with respect to the diameter.
In other words, the driven portion 199 is formed on the upper surface of the first guide 188 on the guide hole 132 side, and as shown in FIG. A rising slope is formed.
Since the driven portion 199 is located below the bottom surface 196 on the front side of the coin in the traveling direction, the second diameter coin 102B rotated by the rotating disk 110 was guided by the second guide body 229 described later. In this case, the user can ride on the driven part 199.
Following the driven portion 199, a flat portion 201 is formed in a portion corresponding to the arc-shaped first diameter guide portion 192B and the second diameter guide portion 194B and a portion corresponding to the outlet passage 116.
Thus, a guide portion 203 for guiding the lower surface of the L-shaped coin is formed by the driven portion 199 and the flat portion 201. This is to smoothly guide the coin.
However, it is only necessary that the guide portion 203 is formed at least in a portion facing the driven portion 199 and the arc-shaped first diameter guide portion 192B and the second diameter guide portion 194B.
In other words, it is not necessary to provide the guide portion 203 facing the outlet passage 116, but the width of the outlet 252 can be made as narrow as possible by forming the guide portion 203 to the vicinity of the outlet 252 of the outlet passage 116. There is an advantage that the insertion of the instrument from the outlet 252 can be prevented as much as possible.
The first guide 188 is supported at its upstream end with respect to the moving direction of the coin 102 so as to be rotatable by a support shaft 202 whose ends are supported by bearings 200A and 200B projecting downward from the back surface of the base plate.
As shown in FIG. 9 (B), the first guide 188 is caused by the elastic force of the spring 308 disposed between the lower surface of the tip 204 of the first guide 188 and the spring seat 206 formed in a channel shape on the back surface of the hopper base 106. A biasing force is applied to 188 in a direction protruding from the bottom surface 196.
However, the first side surface 192A and the first diameter guide portion 192B protrude from the bottom surface 196 by an amount suitable for guiding the first diameter coin 102A by bringing a part 207 of the tip 204 into contact with the back surface of the hopper base 106. It is stationary in the state (state of FIG. 8, position of chain line in FIG. 9B).
In other words, the first guide 188 is normally held at the first guide position GP1 of the first diameter coin 102A where the first diameter guide portion 192B faces the second guide 190 with a predetermined elastic force.
In other words, as shown in FIG. 4, when the first guide 188 is located at the first guide position GP1, the driven portion 199 is inclined with respect to the bottom surface 144, and the flat portion 201 is parallel to the bottom surface 144. Set to
This is because the first diameter guide portion 192B and the first diameter coin 102A are brought into line contact with each other, and the ejecting direction by the second guide 190 is stabilized.

When the first guide 188 rotates about the support shaft 202 from the first guide position GP1 in the clockwise direction as shown in FIG. 9B, the first side wall 192A and the first diameter guide portion 192B are more than the bottom surface 196. It goes down and hides in the mounting hole 198.
Along with this, the second side surface 194A and the second diameter guide portion 194B move to positions facing the second guide 190, and the driven portion 199 is located in the same plane as the bottom surface 196.
In other words, the second side surface 194A and the second diameter guide portion 194B are located at the second guide position GP2 of the second diameter coin 102B.
When the first guide 188 is positioned at the second guide position GP2, the flat surface portion 201 is positioned below the bottom surface 144.

Further, when the first diameter guide portion 192B sandwiches the diameter portion of the first diameter coin 102A with the second guide 190 described later, and the second diameter guide portion 194B sets the diameter portion of the second diameter coin 102B to the first The positions of the first diameter guide portion 192B and the second diameter guide portion 194B are determined so that the movement position of the second guide 190 is the same regardless of whether it is sandwiched between the two guides 190. Yes.
Specifically, the second side surface 194A is farther from the rotation axis of the rotating disk 110 than the first side surface 192A, and the second diameter guide portion 194B is farther from the rotation axis than the first diameter guide portion 192B. In addition, the second guide 190 is disposed at a position away from the standby position SP.

Next, the second guide 190 will be described with reference to FIGS.
The second guide 190 is movably provided and has a function of selectively sandwiching and ejecting the first diameter coin 102A or the second diameter coin 102B between the first diameter guide portion 192B or the second diameter guide portion 194B.
The second guide 190 is a roller 214 that is rotatably supported by the support shaft 212 in the first embodiment.
The second guide 190 is disposed on the side of the rotary disk 110 and the first guide 188, and constitutes one side wall of the outlet passage 116.

The support shaft 212 is fixed to one end of a swinging lever 220 that is pivotally attached to a fixed shaft 218 that is fixed downward on the back surface of the hopper base 106 and passes through an elongated hole 221 of the hopper base 106 to open an outlet. It is located in the exit passage 116 adjacent to 138 and separated from the first guide 188 by a predetermined distance.
The biasing means 216 latched between the pin 173 projecting from the lower surface of the hopper base 106 and the swing lever 220, specifically, the spring 224 is latched so that the roller 214 approaches the first guide 188. Is biased counterclockwise (clockwise in FIG. 5).

The urging means 216 has a function of bringing the second guide 190 close to the first guide 188 elastically.
Normally, the swing lever 220 has a diameter of the small-diameter coin 102A with respect to the first guide 188 by locking a locking portion 226 formed integrally with a locking portion 228 formed on the back surface of the hopper base 106. It is stationary at the standby position SP stopped at a smaller interval.

When the diameter part of the first diameter coin 102A or the second diameter coin 102B moves between the first diameter guide part 192B or the second diameter guide part 194B and the second guide 190, as shown by a chain line in FIG. After the two guides 190 are moved to the payout position DP, the coins 102 are ejected to the exit passage 116 by the resilient force of the biasing means 216.
The second guide 190 is pivoted by the swing lever 220, but can be changed so as to approach and separate from the first guide 188 by linear motion.
Further, the urging means 216 can be changed to a device having a similar function such as an electromagnetic actuator and an air actuator in addition to the spring.

Next, the second guide body 229 will be described with reference to FIGS.
The second guide body 229 protrudes on the bottom surface 144 at a position closer to the rotation axis of the rotary disk 110 than the regulating body 180, and has a function of guiding the second diameter coin 102B in the circumferential direction of the rotary disk 110.
When the second diameter coin 102B is guided by the second guide body 229, the second diameter coin 102B has a predetermined amount of the movable coin guide 230 described later, specifically, a part of the second diameter coin 102A is the first guide 188. To a position opposite to the driven part 199 of
The second guide body 229 is fixed to the other end of the leaf spring 227 having one end fixed to the pin 225 on the back surface of the hopper base 106, and penetrates the through hole 231 (see FIG. 8) of the hopper base 106 from the lower side to the upper side. Projecting on the bottom surface 144, and its tip is located in the second groove 172 of the rotating disk 110.
When the first diameter coin 102A is rotated around the rotating disk 110, the outer edge of the first diameter coin 102A moves along the peripheral wall 150 of the guide hole 132, so that it is hardly guided by the second guide body 229.
However, when the second diameter coin 102B moves along the peripheral wall 150, the inner outer edge thereof is guided by the second guide body 229 and is forcibly moved in the circumferential direction of the guide hole 132, and the movable coin guide 230 described later is moved. Move.

Next, the movable coin guide 230 will be described with reference to FIG. 2, FIG. 3 and FIG.
The movable coin guide 230 constitutes a part of the peripheral wall 150 of the guide hole 132 and has a function of guiding the first diameter coin 102A and the second diameter coin 102B.
In particular, it has a function of guiding the second diameter coin 102B to the driven part 199 of the first guide 188.
The movable coin guide 230 is a movable plate 232 having a predetermined thickness similar to the thickness of the coin disposed on the upper surface of the hopper base 106 and in a recess 233 formed in communication with the mounting hole 198 and the guide hole 132.
The movable plate 232 is rotatably supported by a rotating shaft 234 that is suspended from the upper surface of the hopper base 106, and is arranged so as to be able to swing in parallel with the bottom surface of the recess 233 disposed in the same plane as the bottom surface 144. .
A side surface 236 of the movable plate 232 on the guide hole 132 side constitutes a peripheral wall 150 of the guide hole 132.
The movable plate 232 is guided by a spring 242 that is locked between a latching projection 296 that projects downward from the back surface of the movable plate 232 through the hopper base 106 and a fixed latch pin 240 that projects on the back surface of the hopper base 106. It is biased toward the hole 132.
The movable plate 232 is locked by a stopper 244 and is held stationary so that the side surface 236 becomes the peripheral wall 150 suitable for the first diameter coin 102A.
However, when the second diameter coin 102B is guided in the circumferential direction by the second guide body 229, the movable coin guide 230 is rotated by a predetermined amount by the second diameter coin 102B.
By this rotation, the tip of the side surface 236 is moved to a position smoothly continuing to the second side surface 194A (the state shown in FIG. 11A).

As a result, the second diameter coin 102B reaches the driven part 199 while being guided by the movable coin guide 230, and pushes down the first guide 188 against the elastic force of the spring 308.
Accordingly, since the driven part 199 is located in the same plane as the bottom surface 196, the second diameter coin 102B is continuously guided by the second side face 194A and reaches the second diameter guide part 194B.
Then, it is ejected by the second guide 190 as described above.
After the second diameter coin 102B passes, the movable coin guide 230 is returned until it is locked to the stopper 244 by the spring force of the spring 242.
After the second diameter coin 102B is ejected, the downward pressing force with respect to the first guide 188 disappears, so the first guide 188 is pushed up by the spring 308, and a part 207 of the tip 204 is placed on the back surface of the hopper base 106. It is rotated until it abuts,
As a result, the first side surface 192A and the first diameter guide 192B return to the first guide position GP1 that guides the coin 102A.

Next, the coin detection device 118 will be described with reference to FIG.
The coin detection device 118 has a function of detecting a movement of the second guide 190 by the coin 102 directly or indirectly and outputting a detection signal DS.
The coin detection device 118 according to the first embodiment includes a second guide 190, a swing lever 220 that supports the second guide 190, an action piece 242 that moves in conjunction with the swing lever 220, and a detection means 244 for the action piece 242. It is out.

The action piece 242 is a detected portion 246 that is formed integrally with the swinging lever 220 and is positioned at a predetermined length in an arc shape with the fixed shaft 218 as the center.
The detection unit 244 has a function of outputting an electrical detection signal DS of “H” or “L” when the detected part 246 is detected.
The detection means 244 of the first embodiment is a transmissive photoelectric sensor 248.
The photoelectric sensor 248 is fixed to the back surface of the hopper base 106 via a mounting portion 250.

In the first embodiment, since the photoelectric sensor 248 is located below the hopper base 106 surrounded by the support portion 124, it is extremely difficult to illegally access from the outside.
When the second guide 190 is moved to the payout position DP by the coin 102, the detected part 246 blocks the projection light from the light projecting part to the light receiving part as shown by a chain line in FIG.
By this interruption, the output of the photoelectric sensor 248 changes from “H” to “L”.
When the second guide 190 is positioned from the payout position DP to the standby position SP, the detected part 246 is disengaged from between the light projecting part and the light receiving part, so that the output of the photoelectric sensor 248 changes from “L” to “H”.
When the output of the photoelectric sensor 248 changes from “L” to “H”, the detection signal DS is output.
By counting this detection signal DS, the number of coins 102 paid out can be known.
Therefore, the detection unit 244 can be changed to another method having the same function, and the sensor 262 can be changed to another sensor such as a reflective photoelectric sensor or a metal sensor.
Furthermore, the coin detection device 118 can be configured by directly detecting the movement of the swing lever 220 or the second guide 190.

As described above, the amount of movement of the second guide 190 is the same regardless of whether the first diameter coin 102A or the second diameter coin 102B is paid out.
Therefore, when the action piece 242 is moved by the first diameter coin 102A or the second diameter coin 102B, the timing at which the detected part 246 blocks the optical axis of the photoelectric sensor 248 is the same and conforms to the coin diameter. There is no need to make adjustments.
Strictly speaking, the movement start timing and the movement end timing of the detected part 246 are slightly different depending on the diameter difference of the coin 102.
However, if the difference is about 5 mm in diameter, it is a negligible timing difference and can be considered substantially the same.

Next, the operation of the first embodiment will be described.
The operation when the diameter of the first diameter coin 102A is 25 mm and the diameter of the second diameter coin 102B is 30 mm will be described.
Since the first guide 188 does not receive any external force, it is stationary at the first guide position GP1 by the spring 308.
First, a case where the first diameter coin 102A is paid out will be described with reference to FIG.
When the payout signal instruction signal for the first diameter coin 102A is received, the electric motor 155 rotates, and the rotating disk 110 is rotated clockwise in FIG. 3 via the speed reducer 157 and the rotating shaft 146.
Due to the rotation of the rotating disk 110, the first diameter coin 102A falls into the through hole 158, and the outer half is supported by the upper surface 178 of the coin receiving plate 174, and the inner half is supported by the bottom surface 144.
As a result, the first diameter coin 102A is pushed by the first pushing portion 166, the inner half thereof slides on the bottom surface 144 of the guide hole 132, and the peripheral surface is guided along with the rotating wall 110 while being guided by the peripheral wall 150. The
At this time, the first diameter coin 102A is pushed by the first pushing portion 166 on its outward arc surface, so that the first diameter coin 102A receives a force pushing the first diameter coin 102A toward the center of rotation, and the centrifugal force due to the rotation is applied to the first diameter coin 102A. Although acting, the contact pressure with the peripheral wall 150, the side surface 236, and the first side surface 192A moves in a substantially zero state (FIG. 10 (A)).

The first diameter coin 102A reaches the regulating body 180, and is guided in the guide hole 132, in other words, in the circumferential direction of the rotating disk 110.
At this time, a force is applied to the restricting body 180 from the lateral direction, but it remains substantially perpendicular to the bottom surface 144.
Due to the movement of the first diameter coin 102A in the circumferential direction, the first diameter coin 102A reaches the first guide 188, in other words, between the first diameter guide portion 192B and the second guide 190 (FIG. 10B). .
The first diameter coin 102A is pushed in the circumferential direction further by the second pushing portion 168 following the first pushing portion 166, and the first guide 188 is fixed, so the second guide 190 is moved to the first diameter coin 102A. Thus, the standby position SP is moved to the payout position DP (FIG. 10 (C)).

Thereby, the swing lever 220 is rotated counterclockwise in FIG. 5 about the fixed shaft 218.
When the second guide 190 is moved by the first diameter coin 102A, the action piece 242 that pivots integrally with the swing lever 220 blocks the projection light from the light projecting portion of the photoelectric sensor 248 (shown by the chain line in FIG. 5). ), The output changes from “H” to “L”.

The first diameter coin 102A is substantially laterally passed through the second guide 190 by the elastic force of the biasing means 216 immediately after the diameter portion passes between the first diameter guide portion 192B and the second guide 190. Bounced out and discharged from exit 252 through exit passage 116.
As a result, the second guide 190 returns to the standby position SP.

The action piece 242 interrupts the light shielding of the photoelectric sensor 248 in conjunction with the return movement of the second guide 190 to the standby position SP, so that the projection light from the light projecting unit is received by the light receiving unit.
As a result, the output of the photoelectric sensor 248 changes from “L” to “H”.
Based on the output change from “L” to “H”, the detection means 144 outputs the detection signal DS.
Therefore, by counting this detection signal DS, the number of coins 102 paid out from the exit 252 can be counted.

Next, a case where the second diameter coin 102B having a diameter of 30 mm is paid out will be described with reference to FIG.
As described above, the first guide 188 is stationary at the first guide position GP1.
As described above, the second diameter coin 102B falls into the through hole 158 and is rotated by the rotating disk 110.
The second diameter coin 102B is guided by the second guide body 229, forcibly moved in the circumferential direction of the rotary disk 110, and pressed against the side surface 236 of the movable coin guide 230.
As a result, the movable coin guide 230 is rotated counterclockwise from the position shown in FIG. 3 (FIG. 11A).
The outer peripheral side end portion of the second diameter coin 102B is moved to a position opposite to the driven portion 199 of the first guide 188, and immediately after that, rides on it (FIG. 9 (A), FIG. 11 (B)).
At this time, the position of most of the upper surface side of the second diameter coin 102B is regulated by the back surface 161 of the rotating disk 110.
In other words, since the second diameter coin 102B cannot move upward by a predetermined amount or more, the first guide 188 is rotated clockwise around the support shaft 202 (FIG. 9B).
As a result, the first guide 188 moves to the second guide position GP2.
As a result, the second side surface 194A and the second diameter guide portion 194B guide the second diameter coin 102B.
Thereafter, the second diameter coin 102B is guided by the regulating body 180 (FIG. 11C) and is sandwiched between the second diameter guide portion 194B and the second guide 190, and is ejected as described above (FIG. 11 (D)).
By the movement of the second guide 190, the detection means 244 outputs the detection signal DS as described above.

Next, Example 2 will be described with reference to FIGS.
FIG. 12 is an enlarged plan view and a CC cross-sectional view of the first guide portion in the normal state in the coin hopper according to the second embodiment of the present invention, and the same reference numerals are given to the functional portions as in the first embodiment.
FIG. 13 is a plan view, a rear view, and a DD line cross-sectional view of the first coin guide portion in the coin hopper according to the second embodiment of the present invention.
FIG. 14 is an enlarged plan view and EE sectional view of the first guide portion when the second diameter coin is paid out in the coin hopper of the second embodiment of the present invention.
FIG. 15 is a plan view, a rear view, and a sectional view taken along the line FF of the first coin guide portion in the coin hopper according to the second embodiment of the present invention.

The second embodiment is characterized in that first guide fixing means 260 for fixing the first guide 188 at the first guide position GP1 is arranged.
In other words, the fixing means 260 is a small diameter coin fixing means.
In the second embodiment, the fixing means 260 includes a first stopper 261 extending from the movable plate 232 to the upper side of the first guide 188 and a second stopper 264 extending to the lower side of the first guide 188.

The first stopper 261 extends from the movable plate 232 onto the driven part 199 of the first guide 188.
The driven part 199 of the second embodiment exhibits a toe-up climb slope with respect to the moving direction of the coin 102 in a state where the one end 207 is in contact with the back surface of the hopper base 106.
The lower surface of the first stopper 261 facing the driven part 199 has the same inclination as the inclination of the driven part 199 and can come into surface contact with the driven part 199.

The second stopper 264 is a protrusion that extends laterally from the peripheral surface of the latching protrusion 296 that extends through the bottom hole 266 of the bottom plate of the recess 233 and extends below the hopper base 106 from the lower end of the movable guide 230.
A protrusion 268 extending from the first guide 188 to the opposite side of the support shaft 202 is formed.
In a normal state in which the movable plate 232 is in contact with the stopper 244 by the spring 242 and is stationary, the second stopper 264 is positioned above the protrusion 268 (FIGS. 13B and 13C), and the first guide 188 is opposite. Regulates clockwise rotation.
In other words, the first guide 188 is prevented from moving further upward from the first guide position GP1 by the first stopper 261, and is moved into the mounting hole 198 by the second stopper 264, that is, to the second guide position GP2. The movement is blocked.
Thereby, the first side surface 192A constitutes the peripheral wall 150, and the first diameter guide portion 192B is kept in a fixed state at a position defining the outlet opening 138.

When the second diameter coin 102B is used, as described above, the second diameter coin 102B is guided by the second guide body 299, and the movable coin guide 230 is turned against the pivot shaft 234 as shown in FIG. Turn clockwise.
As a result, the second stopper 264 is disengaged from the relative position to the protrusion 268, and the first guide 188 can be rotated counterclockwise as shown in FIG.
In other words, in the process in which the second diameter coin 102B is rotated by the rotary disk 110, the driven part 199 of the first guide 188 is pushed down by the second diameter coin 102B and moved to the second guide position GP2, The side surface 192A and the first guide portion 192B are retracted in the mounting hole 198, and the second side surface 194A and the second guide portion 194B move to positions facing the second guide 190.
As a result, the second diameter coin 102B is flipped out by the second guide portion 194B and the second guide 190. When the second diameter coin 102A passes through the side surface 236, the movable coin guide 230 attempts to return to the original position by the elastic force of the spring 242, but abuts against the protrusion 268 and cannot return.
After the second diameter coin 102B is flipped out, the first guide 188 is pushed up by the spring force of the spring 308, and the first side face 192A and the first guide portion 192B guide the first diameter coin 192A, the first guide position GP1 Moved to.
Since the protrusion 268 returns to the position of FIG. 13C, the second stopper 364 can also move to the upper side of the protrusion 268.

Thus, the first guide 188 is maintained in a fixed state by the first stopper 261 and the second stopper 264.
When paying out the first diameter coin 102A, the first guide 188 is in a fixed state.
Then, the positions of the first side surface 192A and the first diameter guide portion 192B are stabilized, and there is an advantage that the payout of the first diameter coin 102A is stabilized.
When the first guide portion 1192B is in a fixed state, there is an advantage that baffle means for preventing fraud (for example, JP 2007-323530 according to the application of the present applicant) can be arranged in the outlet passage 116.

Next, Example 3 will be described.
FIG. 16 is an enlarged plan view of the first guide portion in a normal state in Embodiment 3 of the coin hopper of the present invention.
In the third embodiment, first guide fixing means 270 for manually fixing the first guide 188 at the first guide position GP1 is newly provided.
For example, the first guide fixing means 270 forms a through hole 272 in the movable plate 232, and further has a bottomed insertion hole (not shown) in the hopper base 106 below the through hole 272 at the normal position of the movable plate 232. The movable plate 232 can be fixed by forming and inserting the fixing pin 274 into the through hole 272 and the insertion hole.
When the movable plate 232 is fixed, the first guide 188 is fixed to the first guide position GP1 by the first stopper 261 and the second stopper 264.
Thus, the first guide 188 is fixed and is not forcibly moved by an external operation.

When the second diameter coin 102B is used, a second insertion hole (not shown) is provided at a position where the movable coin guide 230 is rotated by the second diameter coin 102B, and the fixing pin 276 is connected to the second insertion hole. Is inserted into the second diameter coin 102B to be fixed at a position suitable for the guide position.
Furthermore, the first guide 188 is fixed to the position where the second side surface 194A and the second guide portion 194B are opposed to the second guide portion 190 by the same fixing means (not shown).
When the first diameter guide portion 1192B or the second guide portion 194B is fixed, there is an advantage that a baffle means for preventing fraud can be arranged in the outlet passage 116.
The first guide fixing means 270 can directly fix the first guide 188.

Next, a fourth embodiment will be described with reference to FIGS.
In the fourth embodiment, when coins 102B having the same diameter are continuously paid out, the movable coin guide 230 is continuously held at a position suitable for the corresponding diameter, and the position of the movable coin guide 230 is illegally changed from the outside. It is characterized by not being able to.
The same parts as those in the first to third embodiments are denoted by the same reference numerals and different structures will be described, but the fourth embodiment is positioned as an improvement of the second embodiment.
The rotating disk 110 according to the fourth embodiment is a known rotating disk that is not equipped with the coin receiving plate 174 like the rotating disk 110 according to the first embodiment (for example, see Japanese Patent Application Laid-Open No. 2004-334614).
In other words, the coin that has fallen into the through hole 158 is rotated by the rotating disk 110 while sliding on the bottom surface 144.

The movable plate 232 according to the fourth embodiment is rotatably supported on the rotation shaft 234.
The rotation shaft 234 is disposed to project upward from the hopper base 106 at a right angle.
With this configuration, the movable plate 232 is rotatably supported in a virtual plane parallel to the hopper base 106.
The bush 280 is fixed to the hopper base 106 by a screw 284 that passes through a plate-shaped passage cover 282 that defines the upper surface of the outlet passage 116.
Therefore, the rotating shaft 234 is constituted by the screw 284 and the bush 280.
A side surface 236 of the movable plate 232 on the rotating disk 110 side constitutes the peripheral wall 150.
The first stopper 261 that is the lower surface of the distal end of the movable plate 232 faces the second driven portion 285 of the first guide 188.
A first guide restricting body 288 is formed below the movable plate 232 in which a first guide stopper 286 extending in parallel with the movable plate 232 is formed.
Specifically, the first guide restricting body 288 and the movable plate 232 are connected by a connecting body 292 at a predetermined interval.
The predetermined interval is an interval at which the first guide 188 can be positioned.
As is clear from the above description and FIG. 24, the movable plate 232, the first guide restricting body 288, and the connecting body 292 constitute a laterally H-shaped rocking body 290.

The first guide stopper 286 is positioned below the first stopper 261 of the movable plate 232, and is formed to protrude upward on the top surface of the distal end portion of the first guide restricting body 288.
The upper surface of the first guide stopper 286 is formed into a flat surface and can come into surface contact with a flat rear surface 294 formed at the end of the first guide 188 on the guide hole 132 side (see FIG. 26).
As is clear from the above description, the movable plate 232, the first guide restricting body 288, and the connecting body 292 form a lateral recess 295 having an opening on the outlet passage 116 side.
In the recess 295, the bearing side end of the first guide 188 is disposed.

The first guide restricting body 288 is reinforced by applying a metal reinforcing plate 293 to the lower surface thereof.
A latching projection 296 that projects downward from the side of the tip of the reinforcing plate 293 is formed, and the spring 242 is latched between the latching pin 240 (see FIG. 21) that projects downward from the lower surface of the hopper base 106. As a result, a predetermined urging force toward the guide hole 132 is applied to the movable plate 232 via the restricting body 288 and the connecting body 292.
A side surface 298 of the first guide stopper 286 of the first guide restricting body 288 is locked at a predetermined position to a stopper 302 (see FIG. 25) protruding from the lower surface of the hopper base 106.
When the first guide restricting body 288 is locked to the stopper 302, the first side surface 192A for guiding the first diameter coin 102A is kept stationary at the first guide position GP1 constituting the peripheral wall 150 of the guide hole 132.
The elastic force of the spring 242 is set so that the first diameter coin 102A does not move by the force of pushing the first side 192A outward due to centrifugal force, and the second guide body 299 forces the second diameter coin 102B to move. When the movable plate 232 is moved in the circumferential direction of the guide hole 132, the movable plate 232 is rotated in the circumferential direction of the guide hole 132 with the rotation shaft 234 as a fulcrum.

Next, the first guide 188 will be described.
The first guide 188 rotates at one end to a support shaft 202 fixed at both ends to a bearing 296 (FIG. 21) disposed on the back surface side of the hopper base 106 and corresponding to the middle of the first stopper 261. It is supported freely.
As shown in FIG. 23, the first guide 188 is disposed in the rectangular mounting hole 198 of the hopper base 106 so as to be vertically movable, and as shown in FIG. 21, the first guide 188 projects downward from the lower surface of the first guide 188. The spring 208 latched between the retaining pin 304 and the retaining pin 306 projecting downward from the back surface of the hopper base 106 is urged with a predetermined force counterclockwise in FIG.
In other words, the first guide 188 is biased so that its upper end protrudes upward from the mounting hole 198.
In other words, the first guide portion 192B is elastically biased so as to protrude from the upper surface of the hopper base 106.
The latch pin 304 passes through a through hole 305 that is a long hole formed in the first guide restricting body 288, and a spring 208 is latched at the lower end portion that penetrates.
The through hole 305 is a long hole so that the regulating body 232, and hence the movable plate 232, can rotate within a predetermined range.

In the first guide 188, even when the first side surface 192A is located at the first guide position GP1 (FIG. 26B), the outer side surface of the hopper base 106 is not exposed to the side surface of the hopper base 106. It is comprised so that it may not be moved by operation from the outside illegally.
In other words, the first guide 188 is covered by the side wall 297 of the hopper base 106.
A cubic large-diameter guide body 301 is fixed by a screw 303 adjacent to the driven part 199 and the flat part 201 on the top surface of the first guide 188.
The side surface adjacent to the driven portion 199 of the large-diameter guide body 301 is a side surface 194A, and the side surface adjacent to the flat surface portion 201 is a second diameter guide portion 194B.
The large-diameter guide body 301 is preferably made of metal in order to improve durability, and the second diameter guide portion 194B is preferably formed in an arc shape.

A disc-shaped soft resin cushioning body 308 is fixed to a projection 307 protruding in a triangular plate shape from the side wall of the first guide 188 below the first guide portion 192A, and the cushioning body 308 is a hopper base. The first guide 192B comes to rest at the first guide position GP1 by contacting the stopper 312 (FIG. 26B) on the back surface of 106.
At this time, the movable plate 232 is located at the first circumferential surface guide position P1 corresponding to the first diameter coin 102A, and the upper surface of the first guide stopper 286 is roughly on the back surface 294 of the side wall of the first guide 188 on the guide hole 132 side. Closely.
In other words, since the restricting body 288 formed with the first guide stopper 286 can only rotate in a direction perpendicular to the rotation direction of the first guide 188, a pressing force acts on the first guide 188. Even so, the position of the first guide stopper 286 does not change, and the first guide 188, in other words, the first guide portion 192B cannot move downward relative to the bottom surface 144 of the guide hole 132.
At this time, since the first stopper 261 is in close contact with the upper surface 300 of the first guide 188 on the side of the driven part 199, the first guide 188 cannot rotate upward relative to the bottom surface 144.
As a result, the first guide 188 cannot rotate in the vertical direction, and remains stationary in the vertical direction with respect to the bottom surface 144.

As shown in FIGS. 26 (B) and 26 (E), the first guide 188 has a trapezoidal shape as viewed from the side, and is adjacent to the upstream side of the driven part 199 with respect to the coin moving direction and can be engaged with the first stopper 261. The tilt angle of the driven part 199 is slightly larger than the upward tilt angle of the upper surface 300.
The first stopper 261 is formed at the same inclination angle as the upper surface 300 of the first guide 188 located at the first guide position GP1.
This is because the acting force on the first stopper 261 is received by the surface.
The second driven portion 285 is an inclined surface that is adjacent to the upper surface 300, is formed on the side opposite to the guide hole 132 with respect to the upper surface 300, and rises as the distance from the guide hole 132 increases.
When the movable plate 232 is rotated by the second diameter coin 102B, the second driven portion 285 contacts the second driven portion 285, and the first guide 188 is brought into contact with the bottom surface 144 using the inclination of the second driven portion 285. Press down against.
A flat portion 287 is formed on the side opposite the guide hole 132 from the second driven portion 285 and connected to the second driven portion 285.
The flat portion 287 is formed in parallel with the upper surface 300.
When the first stopper 261 contacts the flat portion 287, the second diameter guide portion 194B is opposed to the second guide 190, in other words, the second diameter coin portion 102B is formed by the second diameter guide portion 194B and the second guide 190. Pay out.

As shown in FIG. 26 (F), the first guide stopper 286 is formed with a width that is approximately one tenth of the width of the first guide 188.
The inner wall 313 (FIG. 26A) on the guide hole 132 side of the first guide 188 is formed to have a width approximately equal to that of the first guide stopper 286.
An inclined cam 314 is formed at the lower end of the outer wall 315 on the side of the inner wall 313 (FIG. 26 (A)) so as to move away from the bottom surface 144 of the guide hole 132 as the distance from the guide hole 132 increases.
A protrusion 317 protrudes from the upper surface of the restricting body 288 relative to the inclined cam 314, and an inclined surface 319 is formed at the front end to be inclined at the same angle in the same direction as the inclined cam 314.
When the regulating body 288 rotates from the position shown in FIG. 26 to the position shown in FIG. 29, the inclined cam 314 is slightly pushed up by the inclined surface 319 to release the first guide stopper 286 and the back surface 294 and then the inclined surface 319 is inclined. The first guide stopper 286 comes out of the relative position with respect to the back surface 294 while the first guide stopper 286 comes out of the cam 314 from below, and immediately after that, the first stopper 261 contacts the second driven portion 285 to rotate the first guide 188 downward. The second guide portion 194B is set to move to the second guide position GP2 (FIG. 29 (B)) corresponding to the second diameter coin 102B.

As shown in FIG. 26 (F), a second inclined cam 321 is formed on the side opposite to the guide hole 132 that is continuous with the side wall 313 of the first guide 188.
The second inclined cam 321 is inclined in the same direction as the second driven part 285, but has a larger inclination angle than the second driven part 285.
When the restricting body 288 rotates from the position shown in FIG. 29 to the position shown in FIG. 26, when the first stopper 261 is released from the flat portion 287, the first guide 188 is counteracted in FIG. It is rotated clockwise until the buffer 308 contacts the stopper 312 on the back surface of the hopper base 106.
Then, the first guide stopper 286 is rotated to a relative position with respect to the back surface 294, and the protrusion 317 is rotated to a relative position with respect to the inclined surface 319, and the side surface 298 of the first guide stopper 286 is locked by the stopper 302 and stopped.
When the first guide 188 cannot advance below the back surface 294 of the first guide stopper 286, the first inclined surface cam 321 can be pushed up by the upper surface of the first guide stopper 286 to move to the first guide position GP1.

Next, the operation of the fourth embodiment will be described.
When the movable plate 232 is rotated counterclockwise by the second diameter coin 102B guided by the second guide body 299 and moved to the second circumferential surface guide position (P2) as shown in FIGS. 29 (C)), the first stopper 261 of the movable plate 232 presses the second driven portion 285 on the upper surface of the first guide 188.
At the position where the first stopper 261 contacts the second driven portion 285, the first guide stopper 286 is out of the position opposite to the back surface 294 of the side wall 313 of the first guide 188, so the first guide 188 can rotate downward. become.
Since the second driven portion 285 has a slope that rises forward as it moves away from the guide hole 132, it is pushed down by the first stopper 261 that rotates in a plane parallel to the hopper base 106 to the second guide position (GP2). The second side surface 194A forms the guide hole 132, and the coin outlet is formed between the second diameter guide portion 194B and the roller 214.
As a result, the second diameter coin 102B is ejected to the outlet passage 116 by the second diameter guide portion 194B and the roller 214.
When the second diameter coin 102B continues, the next second diameter coin 102B abuts the side surface 236 and continues the second circumferential surface guide position P2 before the front second diameter coin 102B is ejected by the roller 214. Since the first stopper 261 continues to push down the second driven portion 285, the first guide 188 does not move up and down each time the second diameter coin 102B is paid out.
Thereby, since the position of the second diameter guide portion 194B does not change, there is an advantage that the payout of the second diameter coin 102B is stabilized and the durability can be improved.

When the first diameter coin 102A is paid out next to the second diameter coin 102B, even if the second diameter coin 102B is sandwiched between the second guide portion 194B and the roller 214, the movable plate 232 The side surface 236 of the movable b plate 232 is rotated by the spring 242 and is moved to the first circumferential surface guide position P1 constituting the guide hole 132.
As a result, the first stopper 261 deviates from the position in contact with the second driven portion 285.
Further, since the side end portion of the first guide restricting body 288 pushes the second inclined cam 321, the first guide 188 receives the rotational force upward.
However, when the second diameter coin 102B is sandwiched between the second diameter guide portion 194B and the roller 214, the second diameter guide portion 194B does not move due to the elastic force of the spring 208, continue.
When the second diameter coin 102B is flipped out by the second diameter guide portion 194B and the roller 214, the second diameter guide portion 194B is not subjected to movement resistance by the second diameter coin 102B. Due to the elastic force, the buffer body 308 is rotated around the support shaft 202 until it comes into contact with the stopper 312 on the back surface of the hopper base 106, and stops.
As a result, the first diameter guide portion 192B is moved to the first guide position GP1 constituting the guide hole 132.
Accordingly, the first diameter coin 102A is flipped out by the first guide portion 192B and the roller 214.
When the first diameter coin 102A continues, the movable plate 232 continues the first circumferential surface guide position P1, so the first guide 188 also continues the first guide position GP1.
Thereby, the first diameter coin 102A is stably paid out.

  With the configuration of the fourth embodiment, the position of the movable coin guide 230 moves only when coins with different diameters are paid out, so the guide for flipping coins does not move before and after the coins are paid out, so that stable payout is achieved. There are advantages that can be made.
