Description

The present invention relates to a coin rotation feeding method in which coins such as medals or circulation coins used in a slot game machine are paid one by one to a tray, and more specifically, improvement of coin feeding performance and coin feeding co-in rotational delivery mechanism structure is miniaturized, to coin dispensing apparatus and a slot game machine.

Hereinafter, a coin payout device built in a slot game machine of a game hall will be described as an example.
Normally, this type of coin payout device has a hopper for storing a plurality of coins, a rotating disk (feeder disk) for picking up one coin built in the bottom of the hopper, and from the rotating disk to a tray outside the apparatus. The payout chute or the payout conveying path connecting the two.

  For example, in the case of a hopper device as disclosed in Patent Document 1, a hopper tank that stores a large number of medals (hereinafter referred to as coins) and a rotation that sends the stored coins one by one to an outer payout chute Combined with the disc. In order to drive the rotating disk, the output of the motor is transmitted to the rotating disk, whereby the rotating disk is rotated and coins are continuously delivered.

  However, since the rotating disk is installed at an angle on the inner bottom surface of the hopper tank and coins are sent one by one from the bottom of the tank while being rotated obliquely upward, the rotating disk is inclined in the height direction due to the sending structure of the rotating disk. It requires a large space, and also requires a large rotational output to rotate while supporting the load of all coins stacked and stored in the hopper tank, and requires a large motor and a speed reduction mechanism for it. I was trying. Since such a large motor is required, the cost is increased and the coin payout apparatus becomes expensive.

  Furthermore, since the large motor and the speed reduction mechanism are installed below the rotating disk, the position of the rotating disk is further increased in the hopper tank, and the size of the hopper device is increased in the height direction by the height. It was. When such a hopper device is applied to a slot game machine, it occupies a large space in the height direction. For example, there is a restriction in the height direction when expanding the liquid crystal screen provided on the customer service surface. It was the cause that the expandability of the machine was limited.

  Furthermore, when the coin feeding method disclosed in Patent Document 2 of the prior application is used, an internal space of a cylindrical body having a horizontal rotation axis is provided in the coin storage portion, and is disposed in the internal space of the coin storage portion. This is a device for picking up coins one by one and sending them outward by rotating the rotated piece along the inner peripheral surface.

  However, in this case, one side of the coin that has been scraped up by the rotating piece is in contact with the inner peripheral surface of the cylindrical body, but the other surface rotates and remains open. For this reason, when the rotating piece is rotated, other coins stored in the coin storage part may also be rotated, and for this reason, the coins being picked up may come off the rotating piece. When it becomes empty, continuous coin sending is interrupted, and the coin sending efficiency is lowered, resulting in unstable sending.

Therefore, in the present invention, in order to separate and send coins one by one, a dedicated rotation path for one coin is independently configured to ensure coin feeding and to provide reliable and stable sending. a desired performance and miniaturization and co-in rotational delivery mechanism can be achieved, to provide a coin dispensing device and the slot game machine.

The present invention provides a large-diameter cylindrical body in which a coin feeding opening for one coin is opened and fixedly installed on one end face of a cylindrical body, and one end face of the cylindrical body is opened in a coin receiving opening. Small diameter with a coin storage part that stores a plurality of coins in the inner space of the mouth, and a single exit opening that sends out coins one by one from the coin storage part to the outer peripheral surface side, and is rotatably supported by the peripheral surface. A cylindrical body, and a small-diameter cylindrical body interposed in the internal space of the large-diameter cylindrical body, the both cylindrical bodies are arranged in a concentric circle, and an inner peripheral surface of the large-diameter cylindrical body and an outer peripheral surface of the small-diameter cylindrical body are A rotating passage having an independent passage space for one coin for moving the coin in the circumferential direction while being in a planar state between the opposed peripheral surfaces, and a rotational axis of the small-diameter cylindrical body are pivotally supported in the side surface direction. Driving means for rotating the cylindrical body concentrically with the large-diameter cylindrical body, an inner peripheral surface of the large-diameter cylindrical body, and an outer periphery of the small-diameter cylindrical body Are formed on the opposed circumferential surfaces, and the coins guided to the rotating passage are rotated and fed in the plane state based on the rotational force of the small-diameter cylindrical body to move in the circumferential direction, and the coin surface direction is changed. And a feed guide member that moves to a coin delivery port of a large-diameter cylindrical body .

  According to the present invention, an independent rotation path for one coin can be easily configured by superposing two large and small different diameter cylindrical bodies on concentric circles. In particular, since the rotating passage is an independent passage space, when a coin passes through the rotating passage, both front and back surfaces of the coin are guided by the inner peripheral surface of the large-diameter cylinder and the outer peripheral surface of the small-diameter cylinder. Both widths of the coins are guided by the left and right wall surfaces of the internal space, respectively, and the coins are reliably sent out one by one in a state where the periphery of the coins is completely guided. For this reason, coins passing through the rotation path are sent out without contacting the stored coins, so that coins are not sent in the idle state, and stable coins can be sent out with improved sending efficiency.

In addition, since the rotation path is independent, coins can be reliably sent one by one without being affected by other coins, and a small diameter cylinder that constitutes one of the rotation paths when coins are sent. When the body is driven to rotate, a circumferential feeding force can be obtained, so that the coin in the rotating passage can be fed and moved in the circumferential direction by the rotational feeding force of the small-diameter cylindrical body. Then, when coins correspond to the coin delivery opening opened on the peripheral surface of the large-diameter cylindrical body during the coin movement process, coins are sent outward one by one from the coin delivery opening. For this reason, the coins can be separated one by one and continuously sent out by simply rotating the small-diameter cylindrical body.

The small-diameter cylindrical body located in the internal space of the large-diameter cylindrical body uses the outer peripheral surface as a guide surface of the rotation path, and uses the internal space surrounded by the inner peripheral surface of the small-diameter cylindrical body for the coin storage portion. Thus, the space inside and outside the small-diameter cylindrical body is effectively used. For this reason, there is no useless space inside the large-diameter cylindrical body, and the two different rotation paths for coin feeding and storage and the coin storage portion can be configured compactly.

  Further, since the rotating shaft of the small diameter cylindrical body is pivotally supported in the side surface direction, and the peripheral surface of the small diameter cylindrical body rotates in the vertical direction, the driving means for the small diameter cylindrical body can be provided on the side of the small diameter cylindrical body. In addition, the cylinder side and the driving means can be provided separately. Further, only the amount of coins stored in the coin storage portion becomes a rotation load, and if a small rotation path is formed, the load is reduced, and the drive means including the motor and the speed reduction mechanism can be downsized.

  Also, by rotating the small-diameter cylindrical body, the coins in the coin storage unit are led to the rotating passage through the one-sheet outlet, and sent out one by one from the rotating passage through the coin outlet. Is done. At this time, since the coin to be sent out is sent without changing the surface direction of the coin by the feed guide member, the coin is sent out with the same sending posture without changing the direction. For this reason, it is possible to perform highly reliable sending out of coin jamming.

In another configuration of the present invention, a large-diameter cylindrical body in which a coin delivery opening for one coin is opened and fixedly installed on one end face of the cylindrical body, and one end face of the cylindrical body is opened in the coin receiving opening. , A coin storage portion for storing a plurality of coins in the inner space of the coin receiving port, and a single exit opening for sending coins one by one from the coin storage portion to the outer peripheral surface side, open to the peripheral surface and freely rotate A small-diameter cylindrical body that is pivotally supported, and a small-diameter cylindrical body intervening in an internal space of the large-diameter cylindrical body, and both cylindrical bodies are arranged concentrically, and an inner peripheral surface of the large-diameter cylindrical body and a small-diameter cylindrical body A rotary passage having an independent passage space for one coin for moving the coin in the circumferential direction while being in a planar state between the peripheral surfaces facing the outer peripheral surface, and the rotational axis of the small-diameter cylindrical body are pivotally supported in the lateral direction. And a driving means for rotating the small-diameter cylindrical body concentrically with the large-diameter cylindrical body, and an inner peripheral surface of the large-diameter cylindrical body and a small The coin formed on the peripheral surface opposite to the outer peripheral surface of the cylindrical body, and rotated and fed in the circumferential direction while keeping the coin guided to the rotation passage in a planar state based on the rotational force of the small diameter cylindrical body, and the coin A coin rotating and feeding mechanism comprising a feeding guide member that moves to a coin feeding port of a large-diameter cylindrical body without changing the surface direction, and a plurality of coins are stored and opened on the bottom side surface thereof The coin supply port connected to the coin receiving port of the small-diameter cylindrical body and connected to the coin rotating and feeding mechanism, and the coins stored in the hopper through the coin supply port and the coin receiving port It is a coin payout device provided with a supply restriction mechanism for supplying small amounts to the storage unit .

  According to this invention, since the coin rotation delivery mechanism and the hopper are connected and integrated in the lateral direction, coins are continuously supplied from the coin supply port of the hopper to the coin receiving port of the coin rotation delivery mechanism. Can do. For this reason, coins can be continuously sent out from the coin rotation and delivery mechanism to the payout passage without interruption.

  In particular, the coin rotating and feeding mechanism is provided with a rotation sending function for sending coins one by one, and a storage function for storing a large number of coins is provided on the adjacent hopper side. Since the functions can be made independent, the driving means for driving the coin rotation feeding mechanism can also be installed outside the hopper.

  For this reason, the driving means is located outside the hopper, and the small-diameter cylindrical body for separating and transporting the coins is arranged so as not to receive the full load of the coins, so that the drive output is small and can be constructed with a small driving means . Therefore, there is no driving means at the bottom of the hopper, and the space for disposing the driving means with respect to the hopper bottom can be omitted. Therefore, the height of the hopper can be suppressed and the size can be reduced.

  Further, by providing a supply limiting mechanism, coins can be rotated and sent out from the hopper side and supplied to the mechanism side by little, so that coin feeding due to excessive supply can be avoided and smooth and stable delivery performance can be ensured. .

In another configuration of the present invention, it is possible to provide a payout passage for paying out coins sent from the coin feed port of the large-diameter cylindrical body to a tray provided on the customer service surface of the apparatus main body at a higher position. .

  The coins sent out from the coin outlet of the large-diameter cylindrical body are sent upward toward the coins by providing a payout passage for paying out coins to a tray provided on the customer service surface of the apparatus body at a higher position. At this time, coins can be sent out by continuously pushing them up one by one.

  In another configuration of the present invention, a payout passage for transferring the coin sent from the coin delivery port to the tray without changing the surface direction of the coin can be connected between the coin delivery port and the tray. .

  According to this invention, when a coin is delivered from the coin delivery port to the payout passage, it can be delivered without changing the coin face direction. After sending out, the direction of the coin does not change until reaching the tray, so the sending load is small. Therefore, it is possible to obtain a reliable and stable delivery performance without a risk of coin clogging during the transfer of coins at the joint portion.

  When such a coin payout device is provided in a slot game machine, a space in the height direction in the slot game machine can be increased. For example, the liquid crystal display provided on the customer service surface is increased to increase the game performance. The game performance can be expanded.

  According to the present invention, since there is provided a rotation path capable of rotating and feeding coins one by one independently, there is no idle feeding of coins, and the reliability of sending coins one by one with high feeding efficiency is ensured. High delivery performance can be obtained.

  Between the circumferential surfaces that overlap on the concentric circles of two different-diameter cylindrical bodies, a coin is received in a flat state, and a rotational passage for one coin is sent in the circumferential direction to send it out in the flat state. To do.

An embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 shows a slot machine 11 installed in a game hall. This slot machine 11 has a panel 12 and a reel portion 13 at the upper front as a customer service surface, and three parallel operation switches 14 at the center of the front. It has a drive lever 15 on the left side, a return button 16 on the right side, and an insertion port 17 for inserting coins (medals) C. An ashtray 18, a tray 19 and a return port 20 communicating therewith at the lower front side. have.

  A player inserts coins C into the insertion slot 17 one by one, the inserted coins C are selected inside, and the regular coins C determined to be valid are taken into the inside, and are determined to be invalid. The coins have a sorting function for returning them to the return slot 20. The coin C is also returned to the tray 19 when the player depresses the return button 16 to stop the game.

FIG. 2 shows an internal structure in which the front door 11a of the slot machine 11 is opened from the slot machine main body 11b in a single-open manner. On the side of the opened slot machine main body 11b, a game is performed by rotating and stopping, for example, three rows 1 has a reel 21 at the top, a coin payout device 22 for taking in and paying out coins C at the center of the bottom, a power supply device 23 on the left side, and an overflow tank 24 on the right side.

On the other hand, on the front door 11a side, the reel cover 25, the coin sorting device 26 for sorting the suitability of the coin C , the coin return passage 27, and the return port 20 are arranged in this order from the upper part to the lower part of the inner surface.

Next, the coin payout device 22 will be described.
As shown in FIGS. 3 and 4, the coin payout device 22 is roughly composed of a hopper 28, a coin rotation delivery mechanism 29, and a payout passage 30.

  The hopper 28 has a box shape with an open upper surface, and a large number of coins C are stored in this internal space to wait for dispensing. When surplus coins exceeding the storage limit number in the hopper 28 are generated, they are stored in the overflow tank 24 through an overflow passage (not shown).

  As shown in FIG. 5, a half-moon shaped coin supply port 31 having a low central portion is opened at the lowermost portion of one wall surface 28a of the hopper 28. The coin C stored by inclining the inner wall surface of the hopper 28 toward the coin supply port 31 is naturally slid and moved to the lowermost coin supply port 31 by its own weight.

Further, a stirring disk 33 as a supply limiting mechanism 32 is disposed in the hopper 28 immediately before the coin supply port 31.
The stirring disc 33 is provided along one side wall 28a of the hopper 28. As shown in FIG. 16, the upper opening portion of the coin supply port 31 is closed, and coins C are supplied little by little through a gap opened at the lower portion. The gap is set so that it can be made to pass (showing the passing state when feeding one by one in the figure).

  Further, on the front surface of the stirring disk 33, stirring protrusions 33a dispersed in a cross direction are provided so as to increase the stirring efficiency of coins stored in the hopper 28. One end of a rotating shaft 35 extending through one side wall 28a of the hopper 28 is connected to the center of the rear surface to be cantilevered, and the stirring disk 33 is unidirectionally driven based on driving of a first motor M1 described later. The coin C stored in the hopper 28 is stirred by the stirring protrusion 33a and greatly stirred.

Then, the coin C stored in the hopper 28 is tilted into a flat state suitable for supply to the coin supply port 31, and is stored in a large amount or a small amount in the hopper 28 by the rotating action of the stirring disc 33. The supply amount is limited so that a small amount of coins C is supplied to the lowermost coin supply port 31. Therefore, it is possible to facilitate the flow of coins C from inside the hopper 28 to the outer hopper 28.

Next, the coin rotation delivery mechanism 29 will be described.
The coin rotation delivery mechanism 29 includes a rotation path (see FIGS. 7 and 8) 38 including a housing 36 and a rotation drum 37, a drive device 39, and a feed guide member 40.

The housing 36 is formed in a large-diameter cylindrical body with a hook whose one end face is closed and the other end face is opened, and is vertically long for one coin at an intermediate height position along the inner peripheral surface of the outer closed end face. The coin delivery port 41 is opened. On the other hand, the inner open end surface accommodates a rotating drum 37 (to be described later) in the inner space of the large-diameter cylindrical body from the open end surface, and the open surface is closed by the partition plate 42 after the accommodation. Further, the housing 36 housing the rotating drum 37 is connected to the one wall surface 28 a of the hopper 28 through the partition plate 42. Thereby, the housing 36 is integrally attached to the one side wall 28 a of the hopper 28 .

  As shown in FIG. 6, the above-described rotating drum 37 is formed in a small-diameter cylindrical body having one end face closed and the other end face opened, and is housed in the internal space of the housing 36. The open end surface is closed by a partition plate 42, and a lower portion of the partition plate 42 is provided with a coin receiving port 43 that opens in the same half-moon shape corresponding to the coin supply port 31, and passes through the coin from the hopper 28 side. The rotating drum 37 is inclined and connected to a slightly lower position so that C is supplied to the rotating drum 37 side (see FIG. 15).

  An internal space of the rotary drum 37 corresponding to the coin receiving port 43 is provided in a coin storage portion 44 that stores a plurality of coins. Further, a one-sheet outlet 45 for allowing one coin to be sent out from the coin storage unit 44 to the outer peripheral surface side by its own weight one coin at a time in a planar state along the inner peripheral surface of the rotating drum 37 is provided. Open to the circumference. The single-sheet outlet 45 is divided into four equal parts in the circumferential direction in the drawing.

  The rotating drum 37 is rotatably supported by a rotating shaft 35 while being accommodated in a housing 36. For this reason, when the rotating drum 37 receives the rotational force of the rotating shaft 35 and rotates in one direction, the coin C stored in the coin storing portion 44 is placed on the inner peripheral surface of the rotating drum 37 as shown in FIG. 8, 9, and 10, the coin C is located at the lower part of the rotating drum 37 due to its own weight, so that when the coin C corresponds to the one-sheet outlet 45, the coin C With the rotation of the rotary drum 37, C moves from the single sheet outlet 45 to the rotary passage 38 on the outer peripheral surface side.

  In the above-described rotation passage 38, large and small diameter cylindrical bodies of the housing 36 and the rotation drum 37 are concentrically arranged, and the inner peripheral surface of the housing 36 and the outer peripheral surface of the rotation drum 37 at this time are opposed to each other. An independent passage space for one coin is formed between the peripheral surfaces. Then, the coins C are moved along the circumferential surface one by one in the rotation path 38 while being in a flat state.

  As shown in FIG. 11, a first guide pin P1 for feeding coins and a second guide pin P2 for receiving coins are provided on the inner peripheral surface of the housing 36 constituting the rotary passage 38 as shown in FIG. And project.

  The projecting positions of the guide pins P1 and P2 are such that the first guide pin P1 is guided to the coin delivery port 41 so as to guide the coin C toward the coin delivery port 41 opened at the intermediate height position of the housing 36. The second guide pin P2 is protruded to a lower height position away from the coin feeding port 41.

Further, a pin slide allowable spring 40a and its support plate 40b are attached to the outside of the housing 36 through which the first guide pin P1 and the second guide pin P2 are penetrated, and both guide pins P1 and P2 are advanced and retracted in the axial direction. Supports freely. Thereby, the smooth movement of the coin C which is guided here and guided by contacting both guide pins P1 and P2 is ensured.

  Further, on the outer peripheral surface of the rotary drum 37, a coin guide aligning guide 46 for eliminating a shift in the feed width direction of the coin C and an oblique feed guide piece 47 for oblique feeding are projected as a feed guide member 40. Has been established.

  In this case, in order to clearly represent the movement of the two guide pieces 46 and 47 integrally formed on the outer peripheral surface of the rotary drum 37, the rotary drum 37 is not shown in FIG. Only the part with the hatching is taken out and displayed.

  The alignment guide piece 46 has a concave shape that guides the feeding width direction of the coin C on the outer peripheral surface of the rotary drum 37. For this reason, when the coin C is guided to the rotation passage 38, the circular coin C is guided to the center position of the concave portion of the alignment guide piece 46. In this case, a split groove 46a for avoiding a collision with the guide pins P1 and P2 is formed at a position facing the guide pins P1 and P2 in the circumferential direction so that the rotation of the rotary drum 37 is not hindered. Yes.

  The oblique feed guide piece 47 is formed so as to protrude from the open end surface of the rotary drum 37 close to the one-sheet outlet 45 as a reference and toward the closed end surface. For this reason, when the coin C is guided to the rotation passage 38, the oblique feed guide piece 47 pushes up the coin C and feeds it obliquely in the process of rotation of the rotary drum 37, and sends it toward the coin delivery port 41 side. To guide. In this case, a split groove 47a for avoiding a collision with the pins P1 and P2 is formed at a position facing the guide pins P1 and P2 in the circumferential direction so that the rotation of the rotary drum 37 is not hindered. .

  For this reason, in the rotation passage 38, the coin feeding guide action of both the guide pieces 46, 47 and the both guide pins P1, P2 can be caused as the rotary drum 37 rotates.

In addition, since one coin C guided to the rotating passage 38 is an independent passage space for one sheet, both front and back surfaces of the coin C are guided by the inner peripheral surface and the outer peripheral surface, and the coin C both width is guided by the both wall surfaces of the left and right of the passage space, a coin C can be issued fed one by one reliably in a state where the ambient is completely guide the coin C. For this reason, there is no idle feed. In particular, at the time of delivery to the coin delivery slot 41, the coin C is led to the same standing posture as the vertically open state of the coin delivery slot 41. It can be sent out to the coin delivery port 41 as it is. For this reason, smooth sending without coin jamming is obtained.

  The drive device 39 includes a first motor M1 and a speed reduction mechanism 48. The main shaft of the first motor M1 is connected to a speed reduction mechanism 48, and one end of a rotary shaft 35 that is decelerated by a combination of several gears of the speed reduction mechanism 48 and rotates at a constant speed passes through from the outer surface side of the housing 36. Then, the shaft is attached to the rotating drum 37 and the stirring disk 33 to transmit power.

  When the rotating drum 37 and the rotating shaft 35 are integrated, the rotating shaft 35 is inserted into the shaft hole 49 opened at the center of the closed end surface of the rotating drum 37, and is further parallel to both sides sandwiching the shaft hole 49. An anti-rotation block 51 having a rotating shaft 35 penetrated is interposed between the protruding anti-rotation protrusions 50 (see FIG. 6), and the anti-rotation block 51 is secured by a parallel pin 52 to rotate with the rotary drum 37. The shaft 35 is integrated.

  Accordingly, the rotating drum 37 can be rotated concentrically with the housing 36 based on the driving of the first motor M1. At the same time, the stirring disk 33 in the hopper 28 can be rotated. Since the driving of the rotating drum 37 and the stirring disk 33 are driven by one common first motor M1, the first motor M1 and the speed reduction mechanism 48 can be shared. Therefore, the number of motors and the number of parts of the speed reduction mechanism 48 related thereto can be reduced, and motor control is simplified.

Next, the payout passage 30 will be described with reference to FIGS. 12, 13, and 14. FIG.
The payout passage 30 connects between the coin delivery port 41 and the return port 20, and transfers coins C sent from the coin delivery port 41 to the return port 20 one by one. is there.

  The payout passage 30 has two parallel vertically long base plates 53 and a cover plate 54 arranged in a plane, and is interposed between the opposed surfaces to form a passage space holding plate 55 that forms a passage space for one coin. , 56, 57 (see FIG. 5) constitute a vertical passage through which coins C can be pushed up and paid out one by one.

A lower opening that opens obliquely downward and serves as the entrance of the coin C of the payout passage 30 is connected to the coin delivery port 41 of the housing 36 with the same opening shape, and an upper portion that serves as the coin C outlet of the payout passage 30. The upper opening that is vertically long and opens in the horizontal direction is connected to the return port 20 so as to be opposed thereto.

  In this case, the payout passage 30 can be moved upward in the standing posture to the end without changing the surface direction of the coin C by combining the above-described plates 53 to 57 in the surface direction in the standing state. A feed passage without bending is formed. For this reason, when the coin C is delivered from the coin delivery port 41 to the payout passage 30, the coin C can be delivered without changing the surface direction. Further, in the payout passage 30, the orientation of the surface direction of the coin C does not change until it reaches the return port 20, so that the sending load is small, and there is a risk of coin clogging at the joint portion where the coin is delivered and in the middle of conveyance. Highly reliable delivery performance without any problem can be obtained.

  Further, the payout passage 30 has a coin push-up mechanism 58 and a coin position maintaining mechanism 59 in the lower part, and a counting mechanism 60 in the upper part. Furthermore, the cover plate 54 has a passage confirmation window 61 that also serves as a maintenance inspection that is elongated along the longitudinal passage direction.

  As shown in FIGS. 13 and 14, the coin push-up mechanism 58 includes a push-up shaft 62, a spring 63, a plate 64, and a block 65.

  When the coin push-up mechanism 58 moves while the coin C is being sent out from the coin rotation feed mechanism 29, the coin push-up mechanism 58 hits the upper edge of the coin C against the plate 64 and the lower edge of the coin C is slanted. The plate 64 is pushed down by being pushed up by the feed guide piece 47 and sent out, and then the plate 64 returns to its original position by the repulsive force of the spring 63 as the coin C moves. At this time, the coin C is pushed up and moves into the payout passage 30. At this time, the coin C can be sent out upward in order by successively pushing up the coins C one by one. Then, the coin C that has once entered the payout passage 30 is subjected to an action of a coin position maintaining mechanism 59 described later for maintaining the position of the coin so that the coin C is not lowered again by the reciprocating motion of the coin push-up mechanism 58.

  As shown in FIG. 12, the coin position maintaining mechanism 59 is composed of a cover 66 and a ball 67. The coin 67 is a concave cover 66 in a state in which the ball 67 is allowed to protrude and retract from the side surface of the payout passage 30. It covers and is attached to the lower part of the base plate 53.

  When the ball 67 is disposed inside the concave cover 66 and the ball 67 is moving downward at the inner lower part of the cover 66, there is no gap between the cover plate 54 and the ball 67, and the inner upper part of the cover 66 When the ball 67 is moving upward, a gap through which the coin C passes between the cover plate 54 and the ball 67 is formed.

  As a result, when the coin C moves up the payout passage 30, the coin C pushes up the ball 67, and when the coin C stops rising, the ball 67 presses the coin C against the cover plate 54. The coin C is held so as not to fall.

  The counting mechanism 60 includes a top roller 68, a counter arm 69, a spring 70, a sensor 71, and a sensor bracket 72, and is attached to the upper portion of the base plate 53.

  The top roller 68 is attached to the upper opening of the payout passage 30 so as to be able to move up and down. Then, when the coin C pushed up through the payout passage 30 is discharged from the upper opening of the payout passage 30, it passes while pushing up the coma roller 68. At this time, the counter arm 69 interlocked with the coma roller 68 is also pushed up by the coin C, and after the coin C passes, a reciprocating motion is performed in which the counter arm 69 is lowered to the original standby position by the repulsive force of the spring 70. When this reciprocating motion is performed, the counter arm 69 shields and transmits the optical axis of the sensor 71 provided in the sensor bracket 72, and counts the number of coins C to be paid out. The sent coin C passes through the return slot 20 and is paid out to the tray 19 of the slot machine 11.

Next, a specific coin payout operation of the coin payout device 22 configured as described above will be described.
When a payout signal is input from the control unit of the slot machine 11, the first motor M1 of the coin payout device 22 is driven to start paying out the coin C. At this time, as shown in FIG. 15, the rotary drum 37 and the stirring disk 33 are simultaneously driven to rotate by the drive of the first motor M1.

  First, in the hopper 28, as shown in FIG. 4, the stirring disk 33 rotates in one direction, and the coin C stored in the hopper 28 is largely stirred. Due to the stirring action at this time, excessive supply of a large number of coins stored in the hopper 28 is restricted, and the coins C are tilted in small amounts by tilting the coins into a flat state suitable for supply to the coin supply port 31 side. The coin can be supplied to the lowermost coin supply port 31.

  On the other hand, the rotating drum 37 rotates at a constant speed in the coin feeding direction, and the coin C supplied from the hopper 28 via the coin supply port 31 is stored in the coin of the rotating drum 37 as shown in FIG. Enter part 44 in small portions. As shown in FIGS. 8 and 9, when the coin C that has entered the coin storage portion 44 corresponds to the one-sheet outlet 45 that opens on the inner peripheral surface as the rotary drum 37 rotates, the weight of the coin C is reduced. The light is guided to the outer peripheral passage 38 through the sheet outlet 45.

  As shown in FIG. 11A, the coin C guided to the rotation passage 38 is held at a fixed position by being guided by a concave alignment guide piece 46 at the periphery of the coin C during the rotational feeding process. Rotated. Thereafter, as shown in FIG. 11 (B), the front edge of the coin C hits the second guide pin P2 and is slightly changed in direction toward the coin outlet 41, and then the coin C is moved in the feed direction. The trailing edge is pushed up by the oblique feed guide piece 47, and the coin C gradually approaches the coin delivery port 41. Further, when the coin C is pushed up by the oblique feed guide piece 47 and the front edge of the coin in the coin feed direction hits the first guide pin P1, as shown in FIG. The coin C is entered into the coin delivery port 41 with the same standing posture as the vertically long opening shape of the delivery port 41, and the coin C is completely delivered to the coin delivery port 41 as the oblique feed guide piece 47 is pushed up.

The coin C is delivered from the coin delivery port 41 to the payout passage 30 and sent out. At this time, the coin push-up mechanism 58 is pushed upward and pushed up one by one. Further, the coin C is pushed up while being guided by the coin position maintaining mechanism 59 so as not to be lowered. The coins C are discharged from the upper opening of the payout passage 30 one by one to the return opening 20. At this time, the number of coins C released is counted by the counting mechanism 60.

  By continuously performing such sending-out operation, coins corresponding to the number of payout instructions can be paid out. When the payout of coins corresponding to the number of payout instructions is completed, the driving of the first motor M1 is stopped to prepare for the next coin payout operation.

FIG. 17 shows a case where the stirring roller 34 of the supply limiting mechanism 32 provided in the hopper 28 is used. Again the coin C size, can be applied to a case that does not require a large agitation capabilities, such as a small storage capacity of the coin C in the hopper 28. Furthermore, as shown in FIG. 18, the position of the stirring roller 34 in the hopper 28 is configured so that a gap similar to the coin supply port 31 suitable for supplying coins C little by little can be obtained.

  As described above, the coin rotating and feeding mechanism has a rotation sending function for sending coins one by one, and a storage function for storing a large number of coins is provided on the adjacent hopper side. Since the original functions can be made independent of each other, not only the feeding efficiency of the coin rotation feeding mechanism is increased, but also the motor and the speed reduction mechanism for driving the coin rotation feeding mechanism are installed outside the hopper. Can do. For this reason, the motor and the speed reduction mechanism are located outside the hopper, and the rotating drum that separates and conveys the coin is arranged so as not to receive the full load of the coin, and the drive output is small, and the small motor and speed reduction mechanism Can be built. Therefore, there is no motor and a speed reduction mechanism at the bottom of the hopper, and the space for disposing the motor and the speed reduction mechanism with respect to the hopper bottom can be omitted. Therefore, the height of the hopper can be suppressed and the size can be reduced.
