Description

  The present invention relates to a medal payout device incorporated in, for example, a slot machine, and more particularly to a medal payout device and a gaming machine that can be used by switching to an operation according to the size of the medal.

  2. Description of the Related Art Conventionally, a medal payout device built in a gaming machine such as a slot machine is configured to separate a large number of medals stored in a hopper tank one by one by a rotating disk provided at the bottom of the hopper tank. The medal is guided from the rotation feed passage by rotating and feeding the medal to the medal payout guide pin, the medal payout count roller and the game medal guide arranged on the base of the rotation feed passage. The direction was changed to the passage and the medal was paid out (see, for example, Patent Document 1).

  As such a medal payout device, a dedicated medal payout device corresponding to a predetermined medal size operated in a game hall is used. For this reason, when the size of the operated medal is changed, the medal payout device is similarly changed to a dedicated device corresponding to the size of the medal. Since it is uneconomical to replace all the medal payout devices for each gaming machine, it has been desired to use one medal payout device effectively in common.

  Further, when guiding and feeding the medals from the rotation feed passage to the medal payout passage, the direction of the medals can be changed from the rotation feed passage to the medal payout passage and stably guided. A guide member (guide member) for guiding the passage width according to the size of the medal is required (see, for example, Patent Document 2).

JP 2002-263357 A Japanese Patent No. 376649

  Therefore, according to the present invention, when the medal payout device is switched to one of the large diameter medal and the small diameter medal, the existing component can be used effectively without replacing the parts. An object of the present invention is to provide a shared medal payout device and a gaming machine that can efficiently switch to the size of the medal.

  The present invention has a hopper for storing a large number of medals, and a medal receiving port disposed on the bottom of the hopper so as to freely rotate and accepting medals stored in the hopper by dropping under its own weight. The lowermost medal received in the medal receiving opening has a guide blade on the lower surface in a flat posture, and the medal is in a flat posture between the opposing surfaces of the lower base communicating with the medal receiving port. A rotary disc having a rotary feed passage formed by communicating a passage space that can pass to the outer peripheral surface side, a drive mechanism for rotating the rotary disc, and the rotary feed passage as the rotary disc rotated by the drive mechanism rotates. Medals led to the medals paying passages opened and connected to the outer peripheral surface in the rotational feed direction one by one, and the sent medals are sent to the rotational feed passages. A medal payout mechanism including a medal payout mechanism that changes the direction from the medal payout path to the medal payout path side, the medal payout path is set at a higher position, the base is inclined, and the medal payout mechanism is A first guide position on the upper surface of the base, the payout guide piece for changing the direction of the medal from the rotary feed passage side to the medal payout passage side, and the payout guide piece guiding according to the size of the prescribed medal; The medal payout device is configured to be changeable to a second guide position that is guided according to the size of the medal.

  By setting the medal payout passage on the high side of the base, it is possible to correspond to the height position of the medal discharge port of the gaming machine when it is incorporated in the gaming machine, and at the same time the base surface is raised by the wall surface raised to the high level. Is hidden behind and the base surface is closed from the front side, and the arrangement configuration is suitable for preventing goto action from the front side of the gaming machine.

  Furthermore, since the payout guide piece can be selected and arranged in either the first guide position or the second guide position according to the size of the medal, the payout guide piece can be positioned and attached with high accuracy at a preset position. it can. In particular, it is not necessary to adjust the mounting of the payout guide piece, so that the mounting workability is improved and a desired setting change with high reliability can be easily realized.

  As an aspect of the present invention, the medal payout mechanism includes at least the payout guide piece, one payout roller disposed opposite to the branch position of the rotation feed passage and the medal payout passage, and the other payout plate. The payout plate has a mountain shape with the bottom as a reference, the ridgeline length on one side and the ridgeline shape with the top as a boundary for the prescribed medal payout guide, and the ridgeline length on the other side and The ridge line shape can be used for a small-diameter medal payout guide, and a switching means for switching the direction between the specified medal payout guide and the small-diameter medal payout guide by reversing the front and back with respect to the bottom surface at the center can be configured. .

  Thus, one payout plate can be reversed and applied to two different medals. Further, it is a dual-use type efficient dispensing plate because the existing dispensing plate is not reversed but the existing dispensing plate is simply reversed, and can be easily switched in setting change operations.

  As an aspect of the present invention, the contact start end portion that first contacts the medal of the payout guide piece may be provided along the passage bottom surface of the rotary feed passage, and the contact start end portion may be provided with an inclined surface.

  Since the contact start end of the payout guide piece is provided along the bottom surface of the rotary feed passage, the tip of the medal may enter or get caught between the top and bottom surfaces of the contact start end and the bottom surface of the rotary feed passage. There is no gap, and it is possible to reliably eliminate the cause of medal lock in the rotary feed passage.

  Also, by providing an inclined surface at the contact start end of the payout guide piece, even if the medal abutted here is in an unstable posture, the edge of the medal abuts against the inclined surface, so the contact area at the time of contact is small The medal moves smoothly in the payout direction along the inclined surface.

  As an aspect of the present invention, the payout guide piece can be configured to be changeable in the orientation of the first guide position and the second guide position with the shaft support portion of the base as a base point.

  As a result, when changing the placement of the payout guide piece according to the size of the medal, the shaft support portion of the base serves as a positioning reference point, and if the payout guide piece is attached based on this shaft support portion, the payout guide piece can be The setting can be changed to the direction.

  For example, if the positioning shaft of the payout guide piece is made to correspond to the positioning hole of the base, the arrangement position can be determined, and positioning can be performed by fixing with a screw. Also, if the payout guide piece is turned with the screw loosened, the placement can be changed to a desired position without removing the payout guide piece.

  According to the present invention, when the medal payout device is switched to either the large diameter medal or the small diameter medal, the existing components can be effectively used without replacing the parts. It is possible to provide a shared medal payout device and a gaming machine that can efficiently switch to the size of one medal.

  The drawing shows a medal payout device for a slot machine installed in a game hall, and FIG. 1 is a perspective view showing an internal structure in which a front door 12 of the slot machine 11 is opened from the slot machine main body 13 in a single-opening manner.

  On the opened slot machine main body 13 side, a control board 11a on which a control unit for controlling the game of the slot machine 11 is mounted is built in the upper part. In addition, three rows of reels 14 for using the game by rotating and stopping the position of the pattern on the outer peripheral surface are installed at the top, and a medal payout device 15 for taking in and paying out medals M is installed at the lower center. A power supply device 16 is installed on the right side, and an overflow tank 17 is installed on the right side.

  On the other hand, the inner surface on the front door 12 side has a reel cover 18, a medal sorting device (medal selector) 19, a medal return passage 20, a payout connection port 21a, and a return port 21b in this order from the upper surface. ing. And the outer surface of this front door 12 is provided as a customer service surface, and various game operation parts are installed.

  The medals M inserted during the game of the slot machine 11 are taken into the medal sorting device 19, and after being sorted here, the medals M permitted to be accepted are conveyed to the medal payout device 15. On the other hand, the excluded medals rejected by the medal sorting device 19 are returned to the lower plate (not shown) of the front door 12 through the medal return passage 20 and the return port 21b.

Next, the medal payout device 15 will be described.
As shown in the perspective views of FIGS. 2 and 3A, the medal payout device 15 is configured by mounting a rotating disk 23 and a hopper tank (hereinafter referred to as a hopper) 24 on a base block 22. .

  The hopper 24 stores a large number of medals M in an internal space having an inverted quadrangular pyramid shape whose upper surface is opened, and guides the stored medals M to the central portion of the inverted quadrangular pyramid shape by its own weight. It has a storage structure.

  Further, the hopper 24 is provided with an overflow chute 25 for transferring the surplus medals to the overflow tank 17 when surplus medals are generated when the number of stored medals exceeds the storage limit number. The overflow chute 25 has an inclination angle that allows the medal M to be smoothly inclined and transferred, and is arranged along one corner of the upper part in the hopper 24. The surplus medals guided to the overflow chute 25 are discharged from an overflow discharge port 26 opened on one side wall surface of the hopper 24, and the discharged surplus medals are stored in the overflow tank 17 corresponding to the lower side.

  Further, the hopper 24 is provided with a hook portion 27 (see FIG. 3B) for fixing the hopper 24 to the base block 22 in a lower wall portion. Further, a discharge port cover 28 (see FIG. 3A) is provided between the space in the hopper 24 and the overflow chute 25 in order to allow overflowed medals to flow into the overflow tank 17.

  Further, a medal payout port 29 for paying out medals M one by one in a planar posture is opened between the joint surfaces that are the boundaries of the front wall where the hopper 24 and the base block 22 are vertically arranged. The medal payout port 29 is connected in correspondence with the payout connection port 21a leading to the lower plate of the slot machine 11.

  As shown in the perspective view of FIG. 4A, the base block 22 has a substantially square shape, and is a plane formed by inclining the entire upper surface of the base block 22 at a certain angle (for example, 30 degrees). The base inclined surface 30 is provided. The rotating disk 23 and the hopper 24 are mounted on the upper surface of the base inclined surface 30.

  As shown in the perspective view of the bottom surface side of the base block 22 in FIG. 4B, the base block 22 has a lower surface (back surface side) of the base inclined surface 30 formed hollow, and the rotating disk 23 is driven in the back surface hollow portion. A mechanism 32 and a medal detection mechanism 33 are installed.

  At the center of the upper surface of the base inclined surface 30, a rotating shaft 34 is projected from the drive mechanism 32 installed on the back surface of the base block 22 to the upper surface side as shown in FIG. A shaft hole 42 opened at the center of the rotating disk 23 is inserted into and connected to the rotating shaft 34. Further, an anti-rotation spring pin 34a is provided at the upper end of the rotating shaft 34 so as to intersect with the shaft hole 42 and pin engaging portion 42a of the rotating disk 23 from above (see FIG. 6B). And the rotating disk 23 is integrally connected. Therefore, when the drive mechanism 32 is driven to rotate the rotary shaft 34, the rotary disk 23 integrated therewith is rotated.

  Further, a medal payout passage 35 that leads to the medal payout outlet 29 is formed between the middle portion of the upper side of the base inclined surface 30 that is the height of inclination and the outer peripheral surface of the rotary disk 23. The medal payout passage 35 is a groove-shaped passage through which a single medal can be sent out in a planar posture. The outer end portion of the medal payout passage 35 communicates with the medal payout outlet 29, and the inner end portion is The rotating disk 23 communicates with the base inclined surface 30. Therefore, the medal M rotated and sent from the rotary disk 23 is sent out to the higher medal payout passage 35 side in a flat posture.

  On both sides of the upper surface of the inclined lower portion of the base block 22, there is an attachment / detachment port 36 for hooking the hook portion 27 of the hopper 24 and detachably attaching the hopper 24.

  The drive mechanism 32 uses a motor mounted on a motor mounting base (see FIG. 4B) 38 as a driving source, and reduces the speed to a driving gear (not shown) integrated with an output shaft of the motor built in the motor mounting base 38. When the motor rotates, the rotating shaft 34 also rotates, and the rotational force is transmitted to the rotating disk 23 connected to the rotating shaft 34 by engaging the driven gear with the gear on the rotating shaft 34. Thus, the rotating disk 23 is rotated at a constant speed.

  In order to ground the medal payout device 15, a payout plate 51 and a ground plate 15a (see FIG. 4B) contacting the slot machine 11 are arranged on the frame of the base block 22, and these are connected by a grounding harness 15b. Connected.

Next, the structure of the rotating disk 23 will be described.
As shown in FIG. 5 and FIG. 6A, the rotary disk 23 has a shaft-shaped central portion that vertically penetrates a shaft hole 42 and a part of the lower surface communicating with the shaft hole 42 shown in FIG. B), a horizontally long pin engaging portion 42a through which the spring pin 34a is inserted is provided, and the rotary shaft 34 and the spring pin 34a are aligned with the shaft hole 42 and the pin engaging portion 42a, and the lower surface is provided. By inserting the rotary disk 23 from the side, the rotary disk 23 and the rotary shaft 34 are prevented from rotating and are integrally connected.

  Further, the rotary disk 23 is provided with a medal receiving port 44 that divides the circumferential direction into five equal parts on a concentric circle centered on the shaft hole 42 so as to penetrate in the vertical direction. These medal receiving openings 44 are opened to a size that allows one medal to be lowered in a planar posture, and a taper guide portion 44a for smoothly receiving the medal M from above is formed on the upper side thereof. Further, the central portion of the rotating disk 23 is made high and the peripheral portion thereof is made low so as to protrude in a substantially conical shape. As a result, the stored medals M are dispersed from the central portion of the rotary disk 23 and are naturally supplied to the respective medal receiving ports 44 around the medals M.

  Further, on the lower surface of the rotary disk 23, as shown in FIG. 6 (B), there are an inner peripheral wall 39 serving as an inner peripheral guide surface of the rotary feed passage, and five guide blades 45 corresponding to each medal receiving port 44. Is provided.

  The inner peripheral wall 39 protrudes by concentrically surrounding the shaft hole 42 and the pin engaging portion 42a of the rotary disk 23 in a cylindrical shape, and this protruded peripheral wall becomes an inner peripheral surface of the rotary feed passage 46 described later. Further, the inner peripheral wall 39 protrudes with a passage height slightly higher than that of one medal, and is provided corresponding to an inner peripheral guide surface 50 of the base inclined surface 30 described later.

  The guide blades 45 protrude from the lower surface of the rotating disk 23 with a passage height slightly higher than that of one medal, and are formed between the concentric medal inlets 44 adjacent to each other in the circumferential direction of the rotating disk 23. . The guide blades 45 project in an arc shape from the vicinity of the rotation trajectory connecting the centers of the medal receiving ports 44 to the outer peripheral surface of the rotary disk 23. As a result, the guide blade 45 pushes the medal M and rotates it while the rotary disk 23 rotates.

  A concave collision avoiding groove 41a for avoiding a collision with a payout pin 40 (to be described later) is formed in an arc-shaped intermediate portion of each guide blade 45. Similarly, a collision avoidance space 41b is formed between the inner end portion of each guide blade 45 and the inner peripheral wall 39 facing the guide blade 45 in order to avoid a collision with a payout guide piece 48 described later. Yes.

  Since these five guide blades 45 correspond to the lowermost layer of the medal receiving port 44, when the medal M descends the medal receiving port 44 and reaches the lowermost layer, only the lowermost medal M is one. In a state of being separated, the guide blades 45 are pushed and rotated.

  In order to reduce the motor load caused by the load of the medal M stored in the hopper 24 between the upper and lower opposing surfaces of the rotating disk 23 and the base inclined surface 30, a rotating shaft 34 is provided as shown in FIG. Two sheets of a metal flat washer W1 and a resin thrust washer W2 disposed in an annular shape as a center are interposed.

  The rotating disk 23 and the base inclined surface 30 are vertically opposed to each other with a vertical space in which one medal can be transferred, thereby rotating the medal M between the members 23 and 30 one by one. A rotary feed passage 46 is formed.

  Furthermore, the base inclined surface 30 concentric with the rotating disk 23 has an outer peripheral wall 43 that protrudes in an annular shape so as to cover the outer periphery of the lowermost layer of the rotating disk 23 as shown in FIG. The outer peripheral wall 43 and the inner peripheral wall 39 constitute a lateral passage space of the rotary feed passage 46.

  Therefore, the rotary feed passage 46 is configured to place a medal surrounded by the upper and lower opposing surfaces of the upper rotating disk 23 and the lower base inclined surface 30 and the laterally opposing surfaces of the inner peripheral wall 39 and the outer peripheral wall 43. This is a horizontally long space that can be fed into a plane. The medal M reaching here is pushed by the guide blade 45 as the rotating disk 23 rotates, the upper surface of the medal M is guided by the lower surface of the rotating disk 23, and the lower surface of the medal M is guided by the base inclined surface 30. Are rotated and fed one by one. Further, an outer peripheral surface opening 46a for feeding medals is divided into five equal parts in the circumferential direction on the outer peripheral surface of the rotary disk 23 communicating with the outer peripheral surface of the rotary feed passage 46.

  FIG. 7A is a perspective view of the base block 22 with the rotating disk 23 removed. A circular base passage 47 is formed in the center of the base inclined surface 30 of the base block 22 so as to surround the outer peripheral wall 43 and attach the rotating disk 23. In this base passage 47, a plurality of circular dust drop holes 49 are opened along the outer peripheral wall 43 on the inclined lower side.

  Further, on the center side of the base passage 47, a circular one-step lower inner peripheral guide surface 50 for fitting the inner peripheral wall 39 of the rotary disk 23 so as to be rotatable is provided. The flat washer W1 and the thrust washer W2 are accommodated in the inner peripheral guide surface 50, and the inner peripheral wall 39 is mounted on the upper surface thereof.

  The rotating disk 23 rotates clockwise in the figure, and the medal M guided to the rotation feed passage 46 with the rotation of the rotating disk 23 is kept in a flat posture from the lower inclined side on the base inclined surface 30 to the higher inclined side. And a passage structure that continuously rotates and feeds one by one toward the medal payout passage 35 connected to the outer peripheral surface on the inclined high position side in the rotational feed direction.

  Further, on the side of the rotary feed passage 46 facing the medal payout passage 35, a payout guide piece 48 and a payout pin 40 are arranged to change the direction of the medal M from the rotary feed passage 46 to the medal payout passage 35. .

  Further, at a branch position between the medal payout passage 35 and the rotary feed passage 46, a payout plate 51 for guiding the payout by changing the direction of the medal M sent from the rotary feed passage 46 to the medal payout passage 35 side, and a count roller R and a medal detection mechanism 33 (see FIG. 7B) are provided.

  By the way, each medal receiving port 44 has a medal clogging prevention structure devised so as not to cause medal clogging at the medal receiving port 44. In this medal clogging prevention structure, the medal receiving opening 44 is not a perfect circle, and as shown in FIG. 8 (A), a lock release opening 44b provided with a deformed portion capable of releasing the lock of the medal in a circular part. It is comprised and is comprised.

  The lock release opening 44b is opened in a circular shape corresponding to the size of the large-diameter medal M1, and in addition to the circular receiving port, a part of the circular shape is made the size of the small-diameter medal M2. The bulge is bulged outward with a corresponding curvature, and the bulge that opens is small.

  As shown in FIG. 8B, the dharma-type medal receiving port 44 has a taper guide portion 44a with an inclined peripheral edge on the upper side as shown in FIG. 8B. The lock release opening 44b is provided on the side.

  In particular, in the rotary feed passage 46 communicating with each medal receiving port 44, the rotary disk 23 is opposed to the upper surface of the base passage 47, and the collision avoidance space 41b is formed on the center side of the rotary disk 23 in the passage space. Is formed. For this reason, there exists a possibility that the front-end | tip part of the small diameter medal M2 may enter into the collision avoidance space 41b and be locked. Therefore, in order to avoid this, a part of the medal receiving port 44 is formed as a Dharma-type lock release opening 44b.

  As shown in FIG. 9A, in the case of the rotating disk 23a without the lock release opening 44b, the large-diameter medal receiving port 44c opened in the rotating disk 23a remains a perfect circle. The small-diameter medal M2 received in the large-diameter medal receiving port 44c is pushed and rotated by the guide blade 45 in the lowermost layer. At this time, when the small-diameter medal M2 having a large room for movement in the large-diameter medal receiving port 44c approaches the center side of the base passage 47, the tip of the small-diameter medal M2 in this state is, for example, the payout guide piece 48 or other As shown in FIG. 9B, when the small-diameter medal M2 or the payout pin 40 is run, the small-diameter medal M2 is inclined, and the rear end side of the small-diameter medal M2 is pushed downward on the lower surface of the rotary disk 23. As a result, the small-diameter medal M2 cannot be escaped upward from the large-diameter medal receiving port 44c, and the medal payout device 15 cannot be rotated.

  Considering this clogging of the small-diameter medal M2, the reason why the small-diameter medal M2 is locked is that when the small-diameter medal M2 approaches the center of the base passage 47, the tip of the small-diameter medal M2 is the payout guide piece 48 or other The movement of the small-diameter medal M2 is restricted when the rear end of the small-diameter medal M2 becomes unable to move to the upper side of the large-diameter medal receiving port 44c due to riding on the medal, and the medal clogging occurs. Therefore, even if the small-diameter medal M2 approaches the center side of the base passage 47, if there is room for the small-diameter medal M2 to be further displaceable, the lock can be avoided.

  Therefore, the position where the medal clogging of the small-diameter medal M2 is on the center side of the base passage 47 corresponding to the collision avoidance space 41b based on the above-described consideration results. Also, it may be configured on the center side of the base passage 47.

  As a result, the lock release opening 44b has the tip of the small diameter medal M2 as shown in FIG. 9C, for example, the payout guide piece 48, the other small diameter medal M2, or as shown in FIG. Even if the small-diameter medal M2 is inclined by riding on the payout pin 40, the rear end side of the small-diameter medal M2 is opened upward by the lock release opening 44b. It is possible to escape from the lock release opening 44b to above the large-diameter medal receiving port 44c, so that the lock can be avoided naturally.

  10A, the rear end side of the small-diameter medal M2 is pushed by the inner peripheral surface of the medal receiving port 44, and the leading end side is disposed on a payout guide piece 48 described later installed on the upper surface of the base passage 47. When the small-diameter medal M2 comes into contact with an unstable inclination posture, as shown in the enlarged view of FIG. Since the tip is in contact with an inclined surface 48b of a payout guide piece 48, which will be described later, the tip side of the small diameter medal M2 rides on the top surface of the payout guide piece 48 as shown in an enlarged view in FIG. It is possible to avoid the clogging of medals in advance.

  The above-described payout guide piece 48 is a component of the medal payout mechanism, and is disposed on the inner peripheral surface side of the base passage 47 of the rotary feed passage 46 facing the medal payout passage 35. As shown in FIG. 11 (A), the payout guide piece 48 has an elongated plate shape, and a screw stop hole 48a is provided on the base end side formed wide, and the tip end side is narrow. An inclined surface 48b bent downward is provided for the medal guide. In addition, as shown in FIG. 11B, a positioning projection 48c is provided on the lower surface of the intermediate portion.

  As shown in FIG. 11C, the payout guide piece 48 has a screw 52 inserted through a screw stop hole 48a on the base end side in a state where the payout guide piece 48 is disposed in a plane on the upper surface of the base passage 47. The base passage 47 is attached by screwing into a screw hole (not shown) formed on the upper surface. At this time, the portion bent to the tip side of the payout guide piece 48 is either the large-diameter entrance 53 or the small-diameter entrance 54 opened in parallel to the upper surface of the base passage 47 in a rectangular shape. Install in an immersive state.

  Further, when the payout guide piece 48 is attached in correspondence with the large diameter entrance 53, the positioning protrusion 48c of the payout guide piece 48 is fitted into the large diameter positioning hole 55 opened on the upper surface of the base passage 47. In this state, the screw 52 is fixed, so that the payout guide piece 48 is positioned and attached in the direction of the large diameter payout guide.

  Similarly, when the payout guide piece 48 is attached in correspondence with the small diameter entrance 54, the positioning protrusion 48c of the payout guide piece 48 is fitted into the small diameter positioning hole 56 opened in the upper surface of the base passage 47. By fixing the screw 52 in this state, the payout guide piece 48 is positioned and attached in the direction of the payout guide for the small diameter.

  As a result, the payout guide piece 48 can accurately determine the mounting position by the two-point support action of the positioning protrusion 48c and the screw 52. In FIG. 11 (C), the attachment position on the inner peripheral side where the passage width of the rotary feed passage 46 can be widened is set to the large diameter entrance 53, and the passage width of the rotary feed passage 46 becomes narrower on the outer peripheral side. The position is set to the small diameter entrance 54. Then, the elongated tip end side of the payout guide piece 48 is arranged toward the downstream side of the rotary feed passage 46, and the side surface facing the passage side of the payout guide piece 48 that reaches the upstream side becomes the guide guide surface of the medal. .

  Further, the tip end portion of the payout guide piece 48 is attached to a state where the tip end portion of the payout guide piece 48 is depressed from the upper surface of the base passage 47 by immersing the tip end portion of the payout guide piece 48 into one of the entrances 53 and 54. For this reason, the portion that protrudes from the tip of the payout guide piece 48 to the upper surface of the base passage 47 is the contact start end portion 48d that first comes into contact with the medal. Because of the height, there is no gap where the tip of the medal enters or gets caught between the upper and lower surfaces of the contact start end portion 48d and the bottom surface of the base passage 47. Therefore, the cause of the lock of the small diameter medal M2 in the base passage 47 can be surely solved.

  Further, by providing the inclined surface 48b at the contact start end portion 48d of the payout guide piece 48, even if the medal abutted here has an unstable posture, the contact area between the edge of the medal and the inclined surface 48b is small. The medal moves smoothly in the payout direction along the inclined surface 48b without being caught.

  When changing the arrangement direction of the payout guide piece 48, for example, when changing the setting from the attachment position for a large diameter medal to the attachment position for a small diameter medal, as shown in FIG. May be arranged at the small-diameter guide position A2 on the outer peripheral side from the large-diameter guide position A1 corresponding to the small-diameter entrance 54. When changing the setting position from the small diameter medal mounting position to the large diameter medal mounting position, as shown in FIG. 12B, the payout guide piece 48 is arranged on the inner peripheral side corresponding to the large diameter immersion entrance 53. What is necessary is just to arrange | position in the large diameter induction position A1. Accordingly, it is possible to switch the payout guidance corresponding to the size of the two types of medals in the rotary feed passage 46 by simply changing the arrangement position of one payout guide piece 48.

  Thus, since the payout guide piece 48 can be selected from either the large diameter guide position A1 or the small diameter guide position A2, the payout guide piece 48 can be positioned and attached to a preset position with high accuracy. In particular, if the dispensing guide piece 48 is turned with the screw 52 loosened, the arrangement can be easily changed by simply rotating it without removing the dispensing guide piece 48.

Further, the portion of the payout pin 40 disposed on the start end side of the medal payout passage 35 is also configured with a medal clogging avoidance structure.
FIG. 13A shows a state where a medal is nipped between the medal receiving port 44 and the payout pin 40 and is likely to be jammed. FIG. 13B shows a state in which the payout pin 40 that has received the external force in the planar direction is immersed downward to avoid clogging of medals.

  The clogging avoidance structure by the payout pin 40 will be described with reference to FIG. As shown in FIGS. 14A and 14C, the payout pin 40 is provided with a fulcrum pin 57 provided on the lower surface side of the base passage 47, and is pivotally supported by the fulcrum pin 57. The tip end side of the tilt lever 58 is biased upward by the biasing force of the payout pin return spring 59 interposed between the base end side of the tilt lever 58 and the base passage 47. As a result, when the payout pin 40 attached to the tip end side of the tilt lever 58 protrudes from the upper surface of the base passage 47, the protrusion guides the medal toward the medal payout passage 35, and the medal is likely to be jammed. In this case, the upper portion of the payout pin 40 is passed by being tilted by the pressing force of the medal by the rotating disk 23.

  For this reason, when an overload is applied to the payout pin 40 such that the medal clogging occurs, the payout pin 40 receives an overload from the lateral direction due to the medal as shown in FIG. A clogging avoidance structure is provided in which a medal that has been immersed to avoid a load is placed on the upper surface of the payout pin 40 and passed therethrough.

  FIG. 15 shows a shared structure of the payout plate 51. The dispensing plate 51 is made of a highly durable metal material, and has a mountain shape with a base 51a as a reference, as shown in FIG. 15A, and one side (left side in the figure) with the top 51b as a boundary. ) Is the large-diameter medal payout guide side 51c, the ridgeline length and ridgeline shape on the other side (right side in the figure) is the small-diameter medal payout guide side 51d, and the base 51a is used as a reference at the center. And a switching structure capable of switching the orientation of the large-diameter medal payout guide side 51c and the small-diameter medal payout guide side 51d.

  FIG. 15A shows a state in which the small-diameter medal payout guide side 51 d is disposed to face the rotation feed passage 46 and the medal payout passage 35. The small-diameter medal payout guide side 51d is formed in a long linear ridgeline so that the passage width interval with the rotary feed passage 46 becomes the small-diameter medal guide width. Further, in order to secure the width for the small diameter medal of the rotation feed passage 46, the mountain height is set higher (vertical length in the figure) than that for the large diameter medal. Further, the passage width interval of the medal payout passage 35 is also set to a dimension that becomes a small diameter medal guide width.

  FIG. 15B shows a state in which the large-diameter medal payout guide side 51 c is disposed so as to face the rotation feed passage 46 and the medal payout passage 35. The large-diameter medal payout guide side 51c is configured as a ridge line curved in a direction in which the peak height decreases so that the passage width interval of the rotary feed passage 46 becomes the large-diameter medal guide width. Further, the passage width interval of the medal payout passage 35 is also set to a dimension that becomes the large diameter medal guide width.

  And the screw stop hole 51e is opened in the center part of this discharge | emission plate 51, and the positioning long hole 51f and the round hole 51g are opened in the right-and-left both sides. As shown in FIG. 15 (C), at the mounting position of the base passage 47 facing these, a screw hole 47a facing the screw retaining hole 51e, and positioning facing the long hole 51f and the round hole 51g on both sides thereof. Pins 47b and 47c are projected.

  Further, the screw holes 51e are screwed into the screw holes 47a through screws (not shown) with the long holes 51f and the round holes 51g of the payout plate 51 fitted to the positioning pins 47b and 47c on both sides. Thus, it is possible to fix and fix the screw accurately and easily.

  As a result, only one payout plate 51 can be applied to two different medals simply by reversing the front and back. In addition, it is a payout plate that can be used efficiently instead of replacing one part instead of an existing payout plate 51, and can be easily changed even when changing the setting of the passage for the large diameter medal and the small diameter medal. No need for work, less work effort, and easy switching.

  A cutout hole 61 that opens a part of the base inclined surface 30 is provided at a branch position between the rotational feed passage 46 and the medal payout passage 35 facing the payout plate 51. A count roller R, which will be described later, protrudes from the upper surface of the cutout hole 61.

  The count roller R described above is pivotally supported at one end of the count arm 60 as shown in FIG. Further, the count roller R urges the count arm 60 itself by a count arm return spring 63 to a position where it abuts against a stopper 62 provided for the count arm stopper so as to stand by on the front end side of the cutout hole 61. Yes.

  Accordingly, the urging force acts in the direction in which the count roller R receives and pushes back the medal that has been rotationally fed to the branch position, and the count roller R is moved forward and backward in the rotational feed direction following the movement of the medal. As a result, when the medal reaches the entrance of the medal payout passage 35 (the branch position of the passage) from the rotary feed passage 46 side, the medal is played by paying off the medal from the rotary feed passage 46 side to the medal payout passage 35 side. have.

  At a position facing the other end of the count arm 60, the first sensor S1 and the second sensor S2 of the medal detection mechanism 33 are arranged in the rotation direction of the count arm 60. In the stand-by state where the count roller R is not receiving the rotational feeding force of the medal, the medal detection mechanism 33 causes the sensor light-shielding piece at the other end of the count arm to be photoelectrically detected by the biasing action of the count arm return spring 63. One sensor S1 is in an OFF state in which light is shielded between the slit portions.

  On the other hand, in the medal detection state in which the count roller R receives the rotational feeding force of the medal, the sensor light-shielding piece of the count arm 60 rotates against the biasing force of the count arm return spring 63, and the slit of the first sensor S1. When reciprocating so as to cross between the parts, the slit part of the first sensor S1 is temporarily opened and turned on. The second sensor S2 that detects the rotation of the count arm 60 in parallel with the first sensor S1 is temporarily turned off from the on state.

  Thereafter, when the medal M is paid out through the medal payout passage 35, the count arm 60 returns to the original position. Thereby, the first sensor S1 is again shielded by the count arm 60 and returns to the OFF state, and the second sensor S2 is opened and returns to the ON state. Thus, the medal detection mechanism 33 detects the movement of the medal being paid out by the first sensor S1 and the second sensor S2 based on the movement of the count roller R and the count arm 60.

Next, the payout processing operation of the medal payout device 15 set for the small diameter medal will be described with reference to the operation explanatory diagram of FIG.
When a medal payout signal is output from the control unit of the slot machine 11, the medal payout device 15 drives the motor to rotate the output shaft 34. The rotating disk 23 rotates in conjunction with the rotation of the output shaft 34, and the small diameter medal M 2 stored in the hopper 24 is guided to the medal receiving port 44 of the rotating disk 23 based on the rotation of the rotating disk 23. . The small-diameter medal M2 that has entered the medal receiving port 44 descends and reaches the upper surface of the lowermost base passage 47. The small-diameter medals M2 that have reached here are separated one by one by the guide blades 45 as shown in FIG.

  Thereafter, the small-diameter medal M2 advances along the base passage 47, and when it reaches the position of the payout guide piece 48, it is guided in the payout direction by receiving the guide action of the payout guide piece 48 and the payout pin 40. The rotary disk 23 is pushed outward from the outer peripheral surface opening 46a. The extruded small-diameter medal M2 moves with its direction changed as shown in FIG.

  As shown in FIG. 16C, when the small-diameter medal M2 reaches the branch position between the rotation feed passage 46 and the medal payout passage 35, the small-diameter medal M2 comes into contact with the payout plate 51 and the count roller R arranged at the branch position. As shown in FIG. 13D, the small-diameter medal M2 that has come into contact receives the rotational force of the guide blade 45, and is pushed further outward to be urged by the count arm return spring 63. Press and hold to widen the entrance of the medal payout passage 35.

  At that time, the count arm 60 integrated with the count roller R rotates, the sensor light-shielding piece of the count arm 60 is disengaged from between the slit portions of the first sensor S1, and the first sensor S1 is turned from OFF to ON. The second sensor S2 is turned from ON to OFF. Thereafter, the small-diameter medal M2 moves toward the medal payout exit 29 on the flat medal payout passage 35 as shown in FIG.

  Thereafter, the small-diameter medal M2 is sent out of the medal count roller R as shown in FIG. As the medal moves, the count arm 60 is moved in the original return direction by the count arm return spring 63. At that time, the sensor light-shielding piece of the count arm 60 crosses the slit portion of the first sensor S1, stops at the stopper 62, the first sensor S1 is turned off again, and the second sensor S2 is turned on.

  Even if the medal comes into contact with the inclined surface 48b of the payout guide piece 48 or between the payout pin 40 and the medal receiving port 44 and the lock is generated, the medal rides on the payout guide piece 48 or the payout pin 40 and is inclined. By adopting the posture, the pinching force from the inner end side can be avoided, and the occurrence of medal clogging can be avoided in advance.

  In this way, even if the medal clogging action such that the small-diameter medal M2 is sandwiched from both sides in the rotary feed passage 46, the cause of the medal clogging can be solved immediately.

Next, the payout processing operation set for the large diameter medal will be described with reference to the operation explanatory diagram of FIG.
When a medal payout signal is output from the control unit of the slot machine 11, the medal payout device 15 drives the motor to rotate the output shaft 34. The rotary disk 23 rotates in conjunction with the rotation of the output shaft 34, and based on the rotation of the rotary disk 23, the large-diameter medal M 1 stored in the hopper 24 is guided to the medal receiving port 44 of the rotary disk 23. It is burned. The large-diameter medal M <b> 1 entering the medal receiving port 44 descends and reaches the upper surface of the base passage 47. As shown in FIG. 17A, the large-diameter medal M1 reaching here is separated one by one by the guide blades 45 and rotated.

  Thereafter, the large-diameter medal M1 advances along the base passage 47, and when it reaches the position of the payout guide piece 48, it is guided in the payout direction by receiving the guide action of the payout guide piece 48 and the payout pin 40. The rotary disk 23 is pushed outward from the outer peripheral surface opening 46a. The extruded large-diameter medal M1 moves with its direction changed as shown in FIG.

  As shown in FIG. 17C, when the large-diameter medal M1 reaches the branch position between the rotation feed passage 46 and the medal payout passage 35, the large-diameter medal M1 comes into contact with the payout plate 51 and the count roller R arranged at the branch position. As shown in FIG. 13D, the abutting large-diameter medal M1 receives the rotational force of the guide blade 45 and is pushed further outward to be urged by the count arm return spring 63. Continue pushing R to widen the entrance of the medal payout passage 35.

  At that time, the count arm 60 integrated with the count roller R rotates, the sensor light-shielding piece of the count arm 60 is disengaged from between the slit portions of the first sensor S1, and the first sensor S1 is turned from OFF to ON. The second sensor S2 is turned from ON to OFF. Thereafter, the large-diameter medal M1 moves toward the medal payout exit 29 on the flat medal payout passage 35 as shown in FIG.

  Thereafter, the large-diameter medal M1 is sent out of the medal count roller R as shown in FIG. As the medal moves, the count arm 60 is moved in the original return direction by the count arm return spring 63. At that time, the sensor light-shielding piece of the count arm 60 crosses the slit portion of the first sensor S1, stops at the stopper 62, the first sensor S1 is turned off again, and the second sensor S2 is turned on.

Next, a timing chart detected by the first sensor S1 and the second sensor S2 at the time of paying out medals will be described with reference to FIG.
Based on the fact that the first sensor S1 and the second sensor S2 detect the movement of the count arm 60 that is linked to the displacement operation of the count roller R that follows the movement of the medal M and moves in the rotational feed direction, It is detected that the medals payout passage 35 has been sent out from the rotary feed passage 46.

  Then, the second sensor S2 detects the passage of the medal by turning from ON to OFF in a part of the medal detection time zone in which the first sensor S1 detects the medal M (ON), and enters the medal payout passage 35. The passage of the medal M to be sent out is accurately detected. With such a sensor structure, not only the medal M payout operation can be confirmed accurately, but also when an illegal act is performed on the medal M payout operation based on the detection signal.

  Furthermore, since the medal payout passage 35 is set on the higher side of the base inclined surface 30, it is possible to correspond to the height position of the return port 21b for discharging the medal of the slot machine 11 when it is incorporated in the slot machine 11. At the same time, the base inclined surface 30 is hidden behind by the wall surface raised at a high level, and the base inclined surface 30 is closed from the front side, thereby preventing an illegal act (gotting action) from the front side of the slot machine. It becomes the arrangement configuration suitable for.

  Furthermore, when switching to a dedicated path of either a large diameter medal or a small diameter medal, as shown in FIG. 11, the mounting is performed using the currently installed payout guide piece 48 without replacing the parts. What is necessary is just to displace a position in a channel | path width direction, and as shown also in FIG. 15, if the front and back of the discharge | emission plate 51 are reversed, it can switch easily, without requiring a new component.

  As described above, since the payout guide piece can be selected and arranged in either the large diameter guide position or the small diameter guide position according to the size of the medal, the payout guide piece is positioned and attached with high accuracy at a preset position. be able to. In particular, it is not necessary to adjust the mounting of the payout guide piece, so that the mounting workability is improved and a desired setting change with high reliability can be easily realized.
