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 having a medal clogging avoidance structure.

  2. Description of the Related Art Conventionally, a medal payout device (hopper device) built in a gaming machine such as a slot machine removes a large number of medals stored in a hopper tank from a hopper tank by a rotating operation of a rotating disk provided at the bottom of the hopper tank. The medals are separated one by one, and the separated medals are rotated in a plane to collide with the medal payout guide pins protruding on the base (housing support), thereby rotating the medals in the rotation direction. The medal is paid out by changing the direction from the side to the medal payout passage (medal discharge port) (see, for example, Patent Document 1).

  However, in such a hopper device, when a thin medal or an edge of a medal is slanted, a medal that is rotated and rotated in a plane runs on a guide pin for payout, and between the rotating disk and the guide pin. In some cases, the medal was locked and clogged.

  In addition, the rotating disk and base (guide member) are vertically opposed to each other, and the medal rotation feed action by the upper rotating disk guide blade (drive projection) and the medal rotation feed action by the lower guide member There is known a medal payout device (coin sending device) for changing the direction of the sword from the rotary feed passage side to the medal payout passage (outlet groove) side (see, for example, Patent Document 2).

  In this case, the rotation feed passage of the guide member is formed by gradually changing the passage direction outward toward the outside of the rotation feed passage as it approaches the delivery groove. On the other hand, the rotation trajectory of the medal receiving hole (coin hole) of the rotating disk rotates around a rotation axis of the rotating disk while maintaining a certain radius length. Therefore, if some of the medals that are fed in rotation do not fall completely from the coin hole, the medals are pinched between the coin hole of the rotating disk and the rotation feed passage of the guide member, and rotation feeding becomes impossible. Will be caused. For example, depending on the descent timing and attitude of the medal that descends the coin hole, the outer end side of the medal is interposed in the coin hole without descending to the bottom layer of the coin hole, and the inner end side of the medal is the inner circumference of the rotation feed passage of the guide member When the medals are in sliding contact with each other, opposite forces in the outward direction and the inward direction are applied from both sides in the passage width direction, and medals may be jammed in the process of paying out medals.

  Accordingly, the present invention provides a highly reliable medal payout device and gaming machine capable of preventing medal clogging by providing a medal clogging avoidance structure at a portion where medal clogging is likely to occur when paying out medals. With the goal.

  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 slot has a guide blade on the lower surface that rotates and feeds the medal receiving plane in a flat position, and the medal is in a flat position between the opposing surfaces of the lower base communicating with the medal receiving slot. 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. The medals led to are continuously rotated and fed one by one toward the medal payout passage connected to the outer peripheral surface in the rotation feeding direction, and the sent medals are rotated and fed. A medal payout device comprising a medal payout mechanism for changing the direction from the road side to the medal payout passage side and paying out the both sides of the medal in the passage width direction guided by the guide blades on the upper surface of the base In the width direction of the passage connecting the concave base passage that changes the direction from the rotational feed passage side to the medal payout passage side and the rotation trajectory on the inner peripheral side of the base passage and the outer peripheral side of the medal receiving port. A climbing guide surface for avoiding clogging of medals gradually inclined from the inner circumference side of the base passage toward the center side of the base in the vicinity where the distance is substantially equal to the diameter of the medal, and the rotational feed direction of the climbing guide surface A medal payout device including a lowering guide surface for feeding a medal plane that is lowered from the ride-up guide surface to a position immediately before the medal payout passage from the rear stage. Characterized in that there.

  The riding-up guide surface can be formed by an inclined surface or a tapered surface. If a medal clogging force is applied to the medal from both sides during the medal payout process, the inner end side of the medal rides on the guide surface and assumes an inclined posture, so that the pinching force from the inner end side The occurrence of clogging medals can be avoided in advance.

  The descending guide surface is provided at a height at which a medal that has climbed on the climbing guide surface can be dropped to a low level and returned to a normal plane feeding posture. Therefore, if a climbing guide surface is provided in succession to the climbing guide surface at a site where medal clogging is likely to occur, a medal clogging avoidance structure suitable for rotating and feeding out medals can be constructed.

  As an aspect of the present invention, the climbing guide surface can be configured by setting the climbing start end portion along the inner peripheral side of the base passage to be higher than the bottom surface of the base passage and lower than the medal thickness.

  By making the climbing start end portion of the climbing guide surface higher than the bottom surface of the base passage, the guide action at the time of rotating the medal in the base passage is secured. Further, by making the riding start end portion of the riding guide surface lower than the medal thickness, the contact area with the medal edge is reduced. Therefore, when medal clogging is induced by applying a strong clamping pressure to the medal, the end of the medal can easily ride on the guide surface, and medal clogging can be avoided.

  As an aspect of the present invention, the lowering guide surface can be constituted by a stepped portion that is adjacent to a rear stage in the rotational feed direction of the riding guide surface and is cut out substantially perpendicularly from the riding guide surface.

  The descent guide surface is adjacent to the rear stage in the rotational feed direction of the climbing guide surface, thereby enabling a return operation to return the medal from the inclined posture to the horizontal posture by continuously performing the climbing and lowering of the medal. Yes. Further, since the descending guide surface is provided along the inner peripheral side of the base passage, when the medal is rotated and fed, it is guided to the stepped portion that is cut out substantially perpendicularly from the climbing guide surface, and the medal is immediately dropped. Can be returned to the horizontal position.

As an aspect of the present invention, the climbing guide surface and the lowering guide surface can be integrally formed on the upper surface of the base.
By integrally forming the riding-up guide surface and the lowering guide surface on the upper surface of the base, a single unit configuration sharing the base is achieved, and the number of parts can be reduced.

  If the medal payout device configured as described above is used as a gaming machine, a highly reliable operation capable of performing a stable medal payout operation with no medal jamming can be achieved.

  According to the present invention, even if a medal clogging force works in the medal payout process, the medal clogging force can be reliably avoided in the payout process. Therefore, a highly reliable medal payout device that does not cause medal jamming can be obtained.

An embodiment of the present invention will be described below with reference to the drawings.
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. Also, three rows of reels 14 for rotating and stopping the position of the pattern on the outer peripheral surface to use the game 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 at the time of playing 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 transported 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 3, 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 center portion of the lower 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, a lower connecting portion 27 (see FIG. 2) for fixing the hopper 24 to the base block 22 is provided on one side wall of the lower portion of the hopper 24, and between the internal space of the hopper 24 and the overflow chute 25. A discharge port cover 28 (see FIG. 3) is provided to allow only overflowed medals to flow into the overflow tank 17.

  Further, a medal payout opening 29 is provided between the joint surfaces at the boundary of the one side wall where the hopper 24 and the base block 22 are vertically arranged so that the medals m are paid out one by one in a plane posture. 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.

  The base block 22 has a square shape as shown in the perspective view of FIG. 4, and a base inclined surface 30 is formed on the upper surface of the base block 22 by inclining the entire upper surface by a certain angle (for example, 30 degrees). Have. The rotating disk 23, the hopper 24, and the medal direct detection mechanism 31 are mounted on the upper surface of the base inclined surface 30. Further, as shown in the base bottom view of FIG. 5, the base block 22 has a lower surface (back surface side) of the base inclined surface 30 formed hollow, and the drive mechanism 32 of the rotating disk 23 and the medal indirect detection mechanism are formed in the back surface hollow portion. 33 is installed.

  A shaft hole opened at the center of the rotary disk 23 is formed in the central portion of the upper surface of the inclined base 30 on the rotary shaft 34 projecting upward from the drive mechanism 32 installed on the rear surface of the base block 22. 42 is inserted and connected. In this case, an anti-rotation pin 34a (see FIG. 6) is provided at the upper end portion of the rotating shaft 34 so as to intersect with the shaft hole 42 and a horizontally long opening 42a (described later). Are connected together. Accordingly, 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 communicating with the medal payout outlet 29 is formed between one end portion on the upper surface side of the base inclined surface 30 and the outer peripheral surface of the rotary disk 23. The medal payout passage 35 is a concave groove-like passage through which one medal can be paid out in a flat posture. The outer end portion of the medal payout passage 35 communicates with the medal payout outlet 29, and the inner end portion thereof The rotating disk 23 is connected to one opening on the outer peripheral surface. Therefore, the medal m sent out from the rotary disk 23 is sent out to the medal payout passage 35 in a flat posture.

  Further, on both sides of the upper surface of the inclined lower portion of the base block 22, there are attachment / detachment openings 36 for hooking and attaching the lower connecting portion 27 of the hopper 24 detachably. Further, a hooking portion 22 a of the hopper 24 is provided on the inclined upper side of the base block 22.

  The drive mechanism 32 uses a motor M mounted on one side of a motor mounting base (see FIG. 5) 38 as a driving source, and a driving gear (not shown) integrated with the output shaft of the motor M built in the motor mounting base 38. When the driven gear for deceleration is engaged, and this driven gear is engaged with the gear on the rotating shaft 34, the rotational force is transmitted to the rotating disk 23 connected to the rotating shaft 34. Thus, the rotating disk 23 is rotated at a constant speed based on the driving of the motor M.

  Next, the structure of the rotating disk 23 will be described with reference to FIGS. 6 is an exploded perspective view showing the relationship with the rotary disk 23 mounted on the base block 22, FIG. 7 is a perspective view of the rotary disk 23 as viewed from above, and FIG. 8 is a perspective view of the rotary disk 23 as viewed from below. FIG.

  The rotating disk 23 has an integrated structure in which a disk 39 on the upper surface and a disk base 40 on the lower surface are stacked one above the other and are circumferentially fastened by a plurality of screws 41.

  First, as shown in FIG. 7, the disk 39 of the upper surface layer penetrates the shaft hole 42 in the vertical direction at the center of the circular plate, and this shaft hole 42 is formed in a part of the lower surface as shown in FIG. A horizontally long opening 42a through which the pin 34a is inserted is communicated, and the rotary shaft 34 and the pin 34a are aligned and inserted from the lower surface side into the shaft hole 42 and the opening 42a, and a washer from the upper surface side. By screwing and fixing with bolts 43 through 43a, the disk 39 and the rotating shaft 34 are prevented from rotating and are integrally connected.

  Further, the disk 39 penetrates a circular medal receiving opening 44 opened in a vertical direction at a position on a concentric circle obtained by dividing the circumferential direction about the shaft hole 42 into six equal parts so that one medal is lowered in a plane posture. Provided. These medal receiving ports 44 are formed with a taper guide portion 44a on the upper surface side for smoothly receiving the medal m from above. Further, the central portion of the disk 39 is made high and the peripheral portion thereof is made low so as to protrude in a substantially conical shape. Thereby, the stored medals m are dispersed from the central portion of the disk 39 and are naturally supplied to the respective medal receiving ports 44 around the medals m.

  Further, on the lower surface of the disk 39, there are six guide blades 45 corresponding to each medal receiving port 44. The guide blades 45 are respectively formed between the medal receiving ports 44 adjacent in the circumferential direction, and guide a part of the outer peripheral surface of the medal m guided to the lowermost layer of the medal receiving port 44. It has a shape. Since these six guide blades 45 correspond to the upper medal receiving ports 44, when the medal m descends the medal receiving port 44, the medal m is subjected to centrifugal force during rotation by the guide blade 45. Received and guided in the direction of rotational feed.

  In addition, between the upper and lower opposing surfaces of the base block 22 and the rotating disk 23, an annular shape is formed around the rotating shaft 34 in order to reduce the load on the motor M caused by the load of the medal m stored in the hopper 24. A plurality of metal flat washers W1 and resinous thrust washers W2 are interposed.

  The disk base 40 on the lower surface is an annular plate having an outer diameter dimension substantially the same as that of the disk 39. Then, as shown in FIG. 8, the upper disk 39 and the lower disk base 40 are connected to each other by screwing them up and down 41 so that both members 39, 40 are integrated into a two-layer structure. A disk 23 is obtained. A rotation feed passage 46 for the medals m for rotating and feeding the medals m one by one is formed between the two layers of the rotating disk 23.

  The rotary feed passage 46 has a planar passage space for one medal between upper and lower opposing surfaces of the upper disk 39 and the lower disk base 40 communicating with the medal receiving port 44 of the disk 39. The passage space is provided in communication with the outer peripheral surface side. Specifically, it is a space surrounded by the guide blade 45, the lower surface of the disk 39, and the upper surface of the disk base 40. The medal m that reaches this space is caused by the guide blade 45 to rotate the medal m. While the outer peripheral surface is guided, the upper surface of the medal m is guided by the lower surface of the disk 39, and the lower surface of the medal m is guided by the disc base 40 and a base passage 47 described later, so that the medal m is rotated and fed one by one. In this case, in order to stably form a passage for one medal, the disc base 40 is disc shaped so that the space between the upper and lower surfaces of the disc 39 and the disc base 40 is slightly thicker than the thickness of about one medal. It is attached to the lower surface of 39. In addition, an outer peripheral surface opening 46 a for feeding medals that is equally divided in the circumferential direction is opened on the outer peripheral surface of the rotary disk 23 that communicates with the outer peripheral surface of the rotary feed passage 46.

  FIG. 9 is a perspective view of the base block 22 with the rotating disk removed. At the center of the base inclined surface 30 of the base block 22, a circular concave base passage 47 is formed for mounting the rotary disk 23 slightly depressed.

  The base passage 47 has an annular groove 48 corresponding to the disk base 40 on the outer peripheral surface side, and a plurality of dust drop holes 49 are opened in the circumferential direction of the bottom surface of the annular groove 48. Further, the annular groove 48 serves as a relief groove for the head of the screw 41 projecting downward when the disk 39 and the disk base 40 having a two-layer structure are integrally connected to the disk base 40 by fastening them with the screw 41 from above. ing.

  Further, on the inner peripheral surface side of the base passage 47, there is an inner peripheral guide surface 50 that guides the rotation of the medal m that is rotated by the rotary disk 23. Further, the inner peripheral guide surface 50 is provided with a medal clogging elimination structure (described later) that eliminates the occurrence of medal clogging.

  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 maintained 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.

  FIG. 10 is a plan view showing the passing posture of the medal m on the base passage 47, FIG. 11A is a longitudinal sectional view of the main part showing the normal passing posture of the medal m on the base passage 47, and FIG. ) Is a main part longitudinal sectional view showing the passing posture of the medal m inclined to avoid the clogging of medals, and FIG. 11C is a main part vertical sectional view showing a returning operation for returning the medal m from the inclined posture to the horizontal posture.

  As shown in FIG. 10, the inner peripheral guide surface 50 formed on the inner peripheral side of the base passage 47 has an elliptical shape in plan view in which a semicircular shape and a semielliptical shape are joined. It has a circular shape on one side that guides the inner end side m1 of m, and has a nearly circular arc shape for sending and guiding the medal m outward from the middle of the circular shape toward the medal payout passage 35. ing. On the other hand, an outer peripheral guide surface 51 is formed on the outer peripheral side of the base passage 47 that guides the outer end side m2 of the medal m. Thereby, a concave base passage 47 is formed.

  In this case, the passage interval between the inner peripheral guide surface 50 and the outer peripheral guide surface 51 of the base passage 47 has a passage width sufficient for delivery from the medal receiving port 44 near the circular shape of the base passage 47. Then, as the arc shape of the inner peripheral guide surface 50 approaches the medal payout passage 35, the passage width of the base passage 47 gradually becomes narrower, the end of the base passage 47 faces the medal payout passage 35, and the medal m The passage width is suitable for payout.

  The medal m guided here is rotated and guided by the guide blade 45 in a flat posture, and the inner end side m1 of the medal m is guided by the inner peripheral guide surface 50 as shown in FIG. Thus, the direction is changed from the base passage 47 side to the medal payout passage 35 side and paid out.

  By the way, on the upper surface of the base inclined surface 30 along the inner peripheral guide surface 50, there are a riding-up guide surface 52 and a descending guide surface 53 for eliminating the occurrence of clogging of medals.

  The riding-up guide surface 52 is in the vicinity where the distance L of the passage width connecting the inner peripheral guide surface 50 of the base passage 47 and the rotation locus 54 on the outer peripheral side of the medal receiving port 44 is substantially equal to the diameter of the medal m. The base passage 47 is an inclined surface that is gradually inclined from the inner peripheral guide surface 50 toward the center side of the base inclined surface 30, and the inclined surface is elongated along the inner peripheral guide surface 50.

  In the payout process of the medal m, the inner end side m1 of the medal m is the inner peripheral guide of the base passage 47 while the medal m does not descend to the lowermost layer of the medal receiving port 44 as shown by an imaginary line in FIG. When the outer edge side m2 of the medal m is in an unstable inclined posture while being guided by the face 50 and guided in the medal receiving port 44, the inner end portion and the outer end portion of the medal m in the passage width direction. Is sandwiched from both sides, that is, a medal jammed state. In such a case, as indicated by a solid line in FIG. 11B, the medal m can be prevented from being pinched by avoiding the pinching force by the inner end of the medal m climbing on the riding-up guide surface 52 and tilting.

  Therefore, the climbing guide surface 52 sets the height of the inner peripheral guide surface 50 serving as the starting end of the medal m to be higher than the bottom surface of the base passage 47 and lower than the medal thickness. The reason why the height of the inner peripheral guide surface 50 is made higher than the bottom surface of the base passage 47 is to secure the medal m payout guide function in the base passage 47 during normal transport when the squeezing force does not act on the medal. The reason why the height of the inner peripheral guide surface 50 is set lower than the medal thickness is that the contact area with the edge of the medal m is reduced and the end of the medal m rides on the guide surface 52 when the medal clogging is induced. This is to make it easier. Thereby, medal clogging can be easily avoided.

  The descending guide surface 53 is elongated along the inner peripheral guide surface 50 from the rear stage of the ride-up guide surface 52 formed in the rotational feed direction of the base passage 47 to the position immediately before the medal payout passage 35, and on the upper surface of the base inclined surface 30. Form. In this case, when the rotationally sent medal m rides on the climbing guide surface 52, it can be lowered from the climbing guide surface 52 to the lowering guide surface 53 as indicated by a solid line in FIG. . Therefore, the medal m immediately after avoiding the clogging of medals is provided at a height at which the medal m can be returned to the normal plane feeding posture.

  Therefore, if the descending guide surface 53 is connected to the base passage 47 where the medal clogging is likely to occur, the descent guide surface 53 is continuously connected to the medal m avoiding the medal clogging as an invalid medal. It can be paid out as a valid medal as it is. Further, as the shape of the descending guide surface 53, for example, if a stepped portion that is cut out substantially perpendicularly from the riding-up guide surface 52 is formed, the medal m is immediately dropped during the rotational feeding process by the guide blade 45, and the medal m is inclined. Can be returned to a horizontal position. In addition, by placing the lowering guide surface 53 adjacent to the rear stage in the rotational feed direction of the climbing guide surface 52, the medal m can be continuously climbed and lowered.

  Further, the climbing guide surface 52 and the lowering guide surface 53 can be integrally formed on the upper surface of the central portion of the base inclined surface 30 on the base block 22, so that the base guide passage 47 and the medal clogging avoidance structure are provided. Each component of the descending guide surface 53 can be constituted by a single part, and the number of parts can be reduced.

  FIG. 12 is a perspective view of a main part of the medal payout passage 35. The medal payout passage 35 is opened and connected to the terminal end side of the rotary feed passage 46. At the branching position between the medal payout passage 35 and the rotary feed passage 46, the count roller is mainly used for changing the direction of the sent medal m from the rotary feed passage 46 side to the medal payout passage 35 side. R1, the medal relief plate 55, the medal indirect detection mechanism 33 (see FIG. 5), and the medal direct detection mechanism 31 are provided as a medal payout mechanism.

  A cutout hole 56 that opens a part of the base inclined surface 30 along the outer peripheral surface of the rotary disk 23 is provided at a branching position between the rotary feed passage 46 and the medal payout passage 35. The count roller R1 is interposed on the front end side (branch position side) of the cutout hole 56 so as to protrude from the inside of the cutout hole 56 to the upper surface, and the medal relief plate 55 is interposed behind the cutout hole 56.

  As shown in FIG. 5, the count roller R1 is pivotally supported at one end of a count arm 57. Further, the count roller R1 biases the count arm 57 itself by the count arm return spring 58 to a position where it abuts against a stopper piece 57b provided for the count arm stopper so as to stand by on the front end side of the cutout hole 56. ing. Accordingly, the urging force acts in the direction in which the count roller R1 receives and pushes back the medal m that has been rotationally fed to the branch position, and the count roller R1 follows the movement of the medal m and moves forward and backward in the rotational feed direction. As a result, when the medal m reaches the entrance of the medal payout passage 35 from the rotation feed passage 46 side (the branching position of the passage), the medal m is played from the rotation feed passage 46 side to the medal payout passage 35 side. Have.

  At a position corresponding to the other end of the count arm 57, a count sensor S1 as the medal indirect detection mechanism 33 is disposed. In the medal indirect detection mechanism 33, in the standby state where the count roller R1 is not receiving the rotational feed force of the medal m, the sensor light-shielding piece 57a at the other end of the count arm is photoelectrically detected by the biasing action of the count arm return spring 58. It is in the OFF state where light is shielded between the slit portions of the counter sensor S1. On the other hand, in the medal detection state where the count roller R1 receives the rotational feed force of the medal m, the sensor light-shielding piece 57a of the count arm 57 rotates against the biasing force of the count arm return spring 58, and the count sensor S1 When reciprocating across the slits, the slits of the count sensor S1 are temporarily opened and turned on. Thereafter, the medal m moves to the medal payout passage 35 and is paid out, and the count arm 57 returns to the original position, whereby the count sensor S1 returns to the OFF state again. As described above, the medal indirect detection mechanism 33 is indirectly detected by the count sensor S1 based on the movement of the count roller R1 and the count arm 57, based on the movement of the medal m.

  The medal relief plate 55 is disposed for avoiding clogging of medals, and the medal m guided to the branching position between the rotation feed passage 46 and the medal payout passage 35 is rotated near the inner periphery of the rotary disk 23. Even if the medal m guided to the branch position is rotated between the guide blade 45 and the count roller R1 and passes the branch position (see FIG. 14), the medal m remains on the medal release plate 55. It is brought into contact with the tip of the back and moved back.

  In this case, the medal release plate 55 is provided so as to be able to advance and retreat via a medal release spring 59 disposed on the rear end side. When the medal m comes into contact with the tip of the medal release plate 55, the medal release plate 55 is used as a medal. Retreats temporarily against the urging force of the escape spring 59. Thereafter, when the count arm 57 reaches the end position of the rotation limit and the medal m is likely to be jammed, the medal m is pushed back by the pushing back force of the medal release plate 55 and is pushed back to the medal payout passage 35. . Therefore, all medals m guided from the rotary feed passage 46 to the branch position can be guided to the medal payout passage 35.

  The medal payout passage 35 is provided with the count roller R1 in an intermediate portion on the start end side, and on the lower inclined side of the base inclined surface 30 in the passage width on the start end side of the medal payout passage 35 facing the count roller R1. A metal payout plate 60 having good durability is disposed, and the medal direct detection mechanism 31 is disposed on the inclined high side of the base inclined surface 30 in the passage width on the start end side facing the same.

  The medal direct detection mechanism 31 includes a sensor body 61, a sensor cover 62 covering the sensor body 61, and a sensor harness cover 63. The sensor body 61 has a start side sensor S2 and a end side sensor S3 arranged in parallel along the passage direction for photoelectric detection, and covers and protects the outer periphery with both covers 62, 63, The sensor cover 62 is inserted into the sensor mounting hole 64 of the base block 22, and the sensor main body 61 and the covers 62 and 63 are mounted on the base block 22 with screws 65 fixed. The sensor harness cover 63 covers and protects the sensor body 61 and the sensor harness 66 to prevent illegal acts from the outside. Further, when the sensor main body 61 is mounted, the detection light of both the sensors S2 and S3 passes through the light projection hole 67 opened in the upper surface of the medal payout passage 35 in the inclination direction, and the medal payout passage 35 that has passed therethrough. The upper surface is set as a detection area, and the medal m passing there is directly photoelectrically detected.

  Therefore, by providing the medal indirect detection mechanism 33 and the medal direct detection mechanism 31, it is possible to detect in two stages that the medal m has been paid out. In particular, for the medal m to be paid out, a detection configuration is adopted in which the start side sensor S2 detects a time period slightly delayed from the medal detection time period in which the count sensor S1 detects the medal m. As a result, the medal detection information when the medal m is branched from the rotation feed passage 46 and sent to the medal payout passage 35, and the medal m feeding direction is changed from the rotation direction to the straight traveling direction and transferred is precisely obtained. Can be obtained.

  The sensor cover 62 not only covers and protects the sensor body 61, but is also provided on the upper surface of the medal payout passage 35 to form a part of the medal payout passage 35. In order to ground the medal payout device 15, a ground plate 69 is provided in the vicinity of the bottom surface of the frame 68 that contacts the motor M and the slot machine 11, and the ground plate 69 is connected by a grounding harness 70. (See FIG. 5).

The normal medal payout processing operation of the medal payout device 15 configured as described above will be described with reference to the explanatory diagram of FIG.
When a signal indicating the number of medals paid out is output from the control unit of the slot machine 11, the motor M is driven to rotate the output shaft 34. In conjunction with the rotation of the output shaft 34, the rotating disk 23 rotates in the same direction. Based on the rotation of the rotating disk 23, the medals m stored in the hopper 24 are sequentially supplied to the medal receiving port 44 of the rotating disk 23. The medal m that has entered the medal receiving port 44 descends, and the lowermost medal m reaches the upper surface of the base passage 47. The medal m reaching here descends away from the medal receiving port 44 and is rotated and fed by the guide blade 45. Thereafter, the medal m advances along the base passage 47 and is pushed out from the outer peripheral surface opening 46 a of the rotary disk 23.

  As shown in FIG. 13A, the medal m pushed to the outside continues to move along the inner peripheral guide surface 50 or the outer peripheral guide surface 51 of the base passage 47, and the medal m is changed to FIG. 13B. As shown, when the branch position between the rotation feed passage 46 and the medal payout passage 35 is reached, it comes into contact with the payout plate 60 and the count roller R1 arranged at the branch position. As shown in FIG. 13C, the abutted medal m receives the rotational force of the guide blade 45 and is pushed further outward to push the count roller R1 biased by the count arm return spring 58. Continue pushing in the same rotational direction to widen the entrance of the medal payout passage 35.

  At that time, the count arm 57 integrated with the count roller R1 rotates, the sensor light-shielding piece 57a of the count arm 57 is detached from the slit portion of the count sensor S1, and the count sensor S1 is turned off. Thereafter, as shown in FIG. 13 (D), the medal m moves on the medal payout passage 35 on the flat medal payout passage 35 of the base inclined surface 30 and is parallel to the medal direct detection mechanism 31 in the direction of the passage. The slit portion of the start side sensor S2 and the slit portion of the end side sensor S3 are sequentially traversed and turned on in order.

  Thereafter, when the medal m moves toward the medal payout opening 29, the medal m is removed from the medal count roller R1, and the count arm 57 is restored by the count arm return spring 58 as shown in FIG. Move in the direction. At that time, the sensor light-shielding piece 57a of the count arm 57 crosses the slit portion of the count sensor S1, stops at the stopper piece 57b, and the count sensor S1 is turned on again. Further, when the medal m moves in the direction of the medal payout opening 29, as shown in FIG. 13 (F), it passes through the slit portions of the start side sensor S2 and the end side sensor S3, and both these sensors S2, S3 are respectively It turns off in order.

  As described above, in a normal medal m payout operation, the medal m is paid out from the rotation feed passage 46 through the medal payout passage 35, and the payout medal m is normally detected by the detection information of the plurality of sensors S1 to S3. It detects that it has been paid out.

  FIG. 14 is an explanatory view showing the payout operation of the medal m when the medal m is displaced in the passage width direction. As shown in FIG. 14A, the medal m that is rotationally fed through the rotational feed passage 46 by the guide blade 45 moves along the inner peripheral guide surface 50 or the outer peripheral guide surface 51 of the base passage 47. In this case, the medal m may not move to the medal payout passage 35 side, but may move toward the center side in the rotational feed direction as shown in FIG. In this case, the direction of the medal m is not changed to the medal payout passage 35 side, and the medal m continues to push the count roller R1 in the same rotational feed direction as shown in FIG. 14C.

  Thereafter, the medal m tries to advance further by pushing the medal escape plate 55. However, as shown in FIG. 14D, when the count arm 57 integrated with the count roller R1 reaches the end position of the rotation limit, the medal m As shown in FIG. 14E, the push-back force of the medal escape plate 55 is received and pushed back to the medal payout passage 35. Thereby, the medal m moves on the medal payout passage 35 toward the medal payout outlet 29, and the medal direct detection mechanism 31 detects the passage of the medal m. Thereafter, as shown in FIG. 14 (F), the medal m moves toward the medal payout opening 29 and is stably paid out even if the medal m is displaced and fed in the passage width direction.

FIG. 15 is an explanatory diagram showing a medal clogging avoiding operation that can eliminate the occurrence of medal jamming in the rotational feed process.
The inner end m1 of the medal m guided to the rotary feed passage 46 is guided by the inner peripheral guide surface 50 of the base passage 47, and the outer end side m2 of the medal m is unstable while being guided in the medal receiving port 44. In such a case, the medal m is sandwiched from both sides in the passage width direction, and the medal clogging force is activated. In such a case, as shown in FIGS. 15 (A) and 15 (B), the medal m has a pinching force from the inner end side because the inner end side m1 rides on the ride-up guide surface 52 and assumes an inclined posture. The occurrence of clogging medals can be avoided in advance.

  Thereafter, as shown in FIG. 15C, the medals m that have ridden are dropped to a lower position from the climbing guide surface 52 to the descending guide surface 53 when they come to the boundary between the climbing guide surface 52 and the descending guide surface 53. . Thereby, the medal m changes from the inclined posture to the normal plane feeding posture. Thereafter, the medal m is rotated and fed by the guide blade 45 as shown in FIG. 15 (D), and the medal m is moved to the branch position between the rotating feed passage 46 and the medal payout passage 35 as shown in FIG. 15 (E). When it reaches, it contacts the count roller R1. As shown in FIG. 15 (F), the abutting medal m is led out to the medal payout passage 35 by the repelling force of the count roller R1, and is paid out.

  In this way, even if a medal clogging action that sandwiches the medal m from both sides works, it is possible to immediately avoid the medal clogging action. In particular, the medal m can be continuously moved up and down to return the medal m from the inclined posture to the horizontal posture suitable for paying out the medal m, and the medal m can be smoothly returned. .

Next, FIG. 16 shows a timing chart of the sensors S1 to S3 at the time of paying out medals.
The count sensor S1 detects the movement of the count arm 57 in conjunction with the displacement operation of the count roller R1 that is displaced in the rotational feed direction following the movement of the medal m, and the rotation of the medal m by the count sensor S1. It is detected that the payout path 46 has been paid out to the medal payout path 35.

  The start sensor S2 detects (ON) overlapping with a part of the medal detection time zone in which the count sensor S1 is detecting (OFF) the medal m, and similarly the detection (ON) of the start sensor S2 is continued. The presence / absence of the passage of the medal m paid out to the medal payout passage 35 can be accurately detected by the end side sensor S3. Since these three sensors S1 to S3 detect the movement of the medal m along the medal payout direction, not only the payout operation of the medal m can be accurately confirmed, but also an illegal act on the payout operation of the medal m is performed. Even if it breaks, it can be accurately determined.

  As described above, even if a medal clogging force that pinches a medal in the medal payout process works, the medal is placed on the guide surface at a position where the medal clogging is likely to occur, and the medal is inclined. Further, it is possible to avoid the jamming by temporarily avoiding the pinching force. Therefore, a medal clogging avoidance structure can be provided, and a reliable medal payout without medal clogging can be performed.
