  In such a coin-shaped member delivery device, the medal that flows around the tip of the decompression plate and flows onto the rotor is in a bridge state with the medals supported by this portion, and the medals are pressed against each other and locked. It may become. Also, medals that are thrown off by the rotation of the rotor and stand substantially vertically may make it difficult for other medals to flow smoothly into the rotor, or may be bridged or locked with other medals. The situation where the smooth movement of the medals is not possible. This phenomenon occurs more frequently as the medal diameter increases, and the medal with a diameter of 30 mm is larger than the medal with a diameter of 25 mm.

  In view of such a point, the present invention provides a storage container (hopper) for a coin-like member on a base member, and forms a plurality of separation holes to store by rotating a delivery rotor arranged on the base member. In a coin-shaped member feeding device in which coin-shaped members of a container (hopper) are fed one by one to a feeding portion facing the peripheral edge of the feeding rotor, storage is performed for the purpose of damping the pressing load of the coin-shaped member on the sending rotor. A pressure reducing plate is provided in the container (hopper), and a restricting member that acts to restrict the bridge state and the locked state of the coin-like member that flows into the lower side of the pressure reducing plate is provided.

  In the present invention, the coin-shaped member is a generic name including a circular coin, a circular medal, and the like, and in the following embodiment, the coin-shaped member is described as a circular medal. In addition, the thin piece is a general term including a prepaid card and other cards as well as a valuable card for receiving a supply of game medals as well as including a banknote, and the material of the banknote or the card is not limited. .

The coin-shaped member delivery device according to the first aspect of the present invention provides a storage container (hopper) for a coin-shaped member provided on a base member, and forms the storage by rotating a delivery rotor arranged on the base member by forming a plurality of separation holes. In the coin-shaped member delivery device in which coin-like members of a container (hopper) are sent one by one to a delivery unit facing the peripheral edge of the delivery rotor, the storage container (hopper) is directed upward from the delivery rotor. A decompression plate for a coin-like member extending obliquely downward, and a resilient coin-like member restricting member extending in a lateral direction is provided in a space between the decompression plate and the delivery rotor .

A coin-shaped member delivery device according to a second aspect of the present invention provides a storage container (hopper) for a coin-shaped member provided on a base member, forms a plurality of separation holes, and rotates the delivery rotor disposed on the base member to store the storage. In the coin-shaped member delivery device in which coin-like members of a container (hopper) are sent one by one to a delivery unit facing the peripheral edge of the delivery rotor, the storage container (hopper) has a lower side along the outer periphery of the delivery rotor. The wall on the delivery part side and the wall on the opposite side thereof extend outward from the circular shape so that the upper opening has a substantially rectangular shape, and the remaining two walls facing each other are the peripheral edges of the delivery rotor. A decompression plate for a coin-like member extending obliquely downward toward the upper side of the delivery rotor, the decompression plate and the Empty between the delivery rotor Characterized in that a tapered resilient coin-shaped member for restricting member extending laterally.

  According to a third aspect of the present invention, there is provided a coin-shaped member delivery device, wherein a storage container (hopper) for a coin-shaped member is provided on a base member, and a plurality of separation holes are formed to rotate the delivery rotor disposed on the base member. In the coin-shaped member delivery device in which coin-like members of a container (hopper) are sent one by one to a delivery unit facing the peripheral edge of the delivery rotor, the storage container (hopper) has a lower side along the outer periphery of the delivery rotor. The wall on the delivery part side and the wall on the opposite side thereof extend outward from the circular shape so that the upper opening has a substantially rectangular shape, and the remaining two walls facing each other are the peripheral edges of the delivery rotor. It extends substantially vertically from the portion, and is obliquely extended to a position above the rotation center of the delivery rotor or to an position above the delivery rotor beyond the rotation center on the delivery section side in the storage container (hopper). Extend downward A coin-shaped decompression plate for a coin-like member, and tapered toward the space between the decompression plate and the delivery rotor and extending laterally from the wall on the delivery unit side to a position above the approximate rotation center of the delivery rotor. An elastic coin-like member limiting member is provided.

  According to a fourth aspect of the present invention, in the coin-shaped member delivery device according to any one of the first to third aspects of the invention, the coin-shaped member decompression plate has an arcuate tip portion, and the coin-shaped member restriction member has a base portion which is the delivery portion. The distal end portion is fixed to the wall on the portion side and has a substantially conical shape, and a coil spring is formed between the base portion and the distal end portion.

In the first invention, the pressing load attenuation of the coin-like member applied to the delivery rotor is achieved by the decompression plate. Then, the coin-like member that flows into the lower side of the decompression plate and the coin-like member that is blown off by the rotation of the rotor and stands substantially vertically extends in the lateral direction in the space between the decompression plate and the delivery rotor. It collides with the elastic restricting member for coin-like member, and the restricting member is bent. Due to this bending, the movement of the coin-like member is alleviated and the bridge state or the locked state is prevented. Further, since the restricting member flips the coin-like member when returning by elasticity, the posture of the coin-like member on the rotor is prevented from being collapsed to prevent a bridge state or a locked state.

  In the second invention, in addition to the effect of the first invention, in the storage container (hopper) in which the upper opening has a substantially rectangular shape, obliquely downward toward the upper part of the delivery rotor on the delivery part side in the storage container (hopper) By disposing the coin-shaped member decompression plate extending to the side, the load on the coin-shaped member on the delivery portion side is suppressed, and smooth rotation of the rotor is ensured. Furthermore, the tip of the elastic limiting member is tapered. If the tip is flat, the coin-like member that is blown off by the rotation of the rotor and stands substantially vertically maintains the standing posture along the flatness, and other coin-like members are placed on the coin-like member. The coin-shaped members can be stacked on top of each other, making it difficult for the coin-shaped members to flow smoothly into the delivery rotor, but because the taper is tapered, the coin-shaped members fall from a substantially vertical posture by colliding with the tapered portion, and are sent out. It will be in a state of smoothly flowing into the rotor.

  In the third aspect of the invention, by defining the overhang length of the decompression plate and the length of the limiting member in relation to the delivery rotor, this decompression plate suppresses the load load of the coin-like member on the delivery unit side, and the rotor Smooth rotation is ensured. Further, in the space between the decompression plate and the delivery rotor, the bridge state and the locked state of the coin-like member are eliminated by the action of the elastic limiting member, similarly to the effect of the first invention. Further, as in the second aspect of the invention, since the elastic limiting member is tapered, the coin-like member which is blown off by the rotation of the delivery rotor and stands substantially vertically collides with the tapered portion, thereby having a substantially vertical posture. Therefore, the coin-like member standing substantially vertically does not prevent other coin-like members from smoothly flowing into the delivery rotor.

  According to the fourth aspect of the present invention, the tip of the decompression plate is arranged to prevent the coin-shaped member sliding on the decompression plate from concentrating on one part of the delivery rotor and falling by forming an arc shape at the tip. By making the arc shape, the coin-like member that slides on the decompression plate does not concentrate at the center and easily falls from the left and right, so that the load distribution on the delivery rotor can be achieved. The base of the restricting member is stable because the base is fixed to the wall on the sending part side, and the coin-shaped member that collides therewith is freely movable up and down and left and right due to the substantially conical shape of the tip. The reason why the coin-like member is bridged or locked is not stopped and restrained at this portion, and the coin-like member which is skipped by the rotation of the delivery rotor and stands substantially vertically is the substantially cone-shaped portion. Since the coin-shaped member standing substantially vertically does not make it difficult for other medals to smoothly flow into the delivery rotor.

The coin-shaped member delivery device according to the present invention includes a storage container (hopper) for a coin-shaped member provided on a base member, and forms a plurality of separation holes to rotate the delivery rotor disposed on the base member. In the coin-shaped member feeding device in which the coin-shaped members of the (hopper) are fed one by one to the feeding portion facing the peripheral edge of the sending rotor, the storage container (hopper) is inclined toward the upper side of the sending rotor. A coin-shaped member decompression plate extending downward, and a resilient coin-shaped member restricting member extending in a lateral direction in a space between the decompression plate and the delivery rotor are provided to implement the present invention. Examples are described below.

  The medal sending device 2 which is a coin-like member sending device has the following configuration. That is, on the synthetic resin base member 4, a synthetic resin storage container (hopper) 5 </ b> P that forms the accommodating portion 5 for accommodating the medal 100 that is a circular coin-shaped member is attached to the base member 4. It is detachably attached by a screw or a locking device. On the base member 4, a synthetic resin delivery rotor 7 having a plurality of separation holes 10 is arranged in a substantially horizontal state. The delivery rotor 7 is connected to the base member 4 from the electric motor device 8 attached to the rear side of the base member 4. 4 is attached to the tip of the rotating shaft 9 that penetrates through the upper wall of 4.

  The storage container (hopper) 5P has openings 5A and 5B on the upper surface and the lower surface, respectively. The lower surface opening 5B has a circular shape along the outer periphery of the sending rotor 7, and the sending portion is formed so that the upper opening has a substantially rectangular shape. A side wall and a facing wall extend outward from the circular shape, and the remaining two facing walls extend substantially perpendicularly from the peripheral edge of the delivery rotor, and the lower side is circular and the upper side is It has a rectangular container shape. A delivery rotor 7 is arranged corresponding to the lower surface opening 5B.

  As shown in FIG. 4, the delivery rotor 7 attached to the tip of the rotating shaft 9 is arranged in a substantially horizontal state in a circular recess 4A formed on the upper surface of the base member 4, and is slightly separated from the surface of the recess 4A. In this state, the motor device 8 rotates in the R direction as shown in FIG. A rotor guide ring 20 is provided so as to cover the peripheral surface and the peripheral surface of the upper surface of the delivery rotor 7 with a slight gap between the peripheral surface and the peripheral surface of the upper surface of the transmission rotor 7. The rotor guide ring 20 is mounted on a circular step portion 4B formed at a position higher than the recess 4A so as to surround the recess 4A, and a predetermined position of the base member 4 by a locking claw portion 21 formed on the base member 4. Retained. The rotor guide ring 20 forms a ring portion 20B that is inclined so as to spread outward from the ring portion 20A that covers the peripheral edge of the upper surface of the delivery rotor 7, and as shown in FIG. 4, the storage container (hopper) 5P A storage container (hopper) 5P is attached to the base member 4 so that the circular lower surface opening 5B extends along the ring portions 20A and 20B.

  With the delivery rotor 7 attached to the tip of the rotating shaft 9 and disposed in the recess 4A, the notches 20C formed at a plurality of positions on the peripheral edge of the rotor guide ring 20 are made to correspond to the respective locking claws 21. The rotor guide ring 20 is placed on the stepped portion 4B, and in this state, the rotor guide ring 20 is rotated clockwise in FIGS. 2 and 3, as shown in FIGS. The rotor guide ring 20 sinks into the lower side of the locking claw portion 21 and is locked, and the end portion 20D of the rotor guide ring 20 comes into contact with the stopper step portion 22 formed on the base member 4, so that the rotor guide ring 20 is held in place.

  As shown in FIG. 3, the delivery rotor 7 has a disk shape in which a plurality of separation holes 10 (the one shown in the figure has six separation holes, but is not limited thereto) are arranged at substantially equal intervals on a concentric circle. Each separation hole 10 has a diameter slightly larger than the diameter of the medal 100 and passes through the delivery rotor 7 in a circular shape up and down, and spreads downward and inclined downward on the downstream side in the rotation direction R at the upper peripheral edge. A guide surface 11 is formed. Further, an open outlet 10A that faces the periphery of the delivery rotor is formed at the lower peripheral edge of each separation hole 10, and a streamline type that extends to the periphery of the delivery rotor 7 is formed downstream of the open outlet 10A in the rotation direction R. An extruded wall 12 is formed.

  As shown in FIG. 4, in the recess 4 </ b> A on the upper surface of the base member 4, a sending part 13 for the medal 100 is formed so as to face the peripheral part of the sending rotor 7. Corresponding to the inlet side of the delivery part 13, a conical delivery guide pin 45 is provided on the rotation trajectory of the separation hole 10 so that the delivery guide pin 45 does not collide with the lower surface of the delivery rotor 7. A circular groove 45 </ b> A centering on the rotation shaft 9 is formed in the newly formed circular recess 4 </ b> A.

  With this configuration, the medal 100 of the storage container (hopper) 5P is separated one by one and sequentially enters the separation hole 10 by the rotation of the sending rotor 7, and the medal 100 that has entered the bottom of the separating hole 10 is sent to the sending rotor 7. With the rotation of the base member 4, it slides on the upper surface of the base member 4 and collides with the delivery guide pin 45, toward the delivery part 13 formed on the upper surface of the base member 4 by the pushing wall 12, from the open outlet 10 A to the outside of the delivery rotor 7. It is a mechanism that is pushed out toward the direction. Thus, one medal 100 is sent out from each separation hole 10 with the rotation of the sending rotor 7.

  The medal 100 pushed out of the sending rotor 7 with the rotation of the sending rotor 7 enters the sending unit 13 constituting the coin-shaped member passage. At the entrance of the delivery unit 13, the fixed side wall 15 and the movable body 16 are located at a position slightly smaller than the diameter of the medal 100 at a position where the medal 100 pushed outward from the delivery rotor 7 first passes. Is arranged. The medal 100 that has entered the bottom of the separation hole 10 with the rotation of the delivery rotor 7 moves to the outside of the delivery rotor 7 from the opening 10A, contacts the inclined surface 15B on the inner side of the fixed side wall 15 and the delivery guide pin. It collides with 45 and is pushed by the pushing wall 12 while being rotated.

  The medal 100 pushed out of the sending rotor 7 in this way enters the sending unit 13 and passes through the sending unit 13 in the Y1 direction as shown in FIG. It is sent out from the outlet 14. As shown in FIG. 9, the medal 100 delivered from the delivery port 14 is supplied to the tray 1D provided on the front surface of the gaming machine 1 through the nozzle 2N, and can be used for the next game by the player. The passage width T <b> 1 of the delivery unit 13 is formed by an interval between the straight part 15 </ b> A at the tip of the fixed side wall 15 and the fixed side wall 26 arranged in parallel to the fixed side wall 15 on the opposite side. The passage width T1 is set to a dimension slightly larger than the diameter of the medal 100 so that the medal 100 can move smoothly.

  As shown in FIG. 3, the fixed side wall 15 is provided at a position where the medal 100 delivered from the delivery rotor 7 abuts on the front side in the rotational direction (R) of the delivery rotor 7 on the entrance side of the delivery unit 13. In consideration of wear resistance, it is made of metal, and in the embodiment, it is made of stainless steel. The movable body 16 is positioned in front of the fixed side wall 15 in the rotational direction (R) of the delivery rotor 7 and is provided in a state of being biased by a spring 17 so as to be pressed and operated by the medal 100. The movable body 16 is composed of a cylindrical body 16A rotatably attached to a shaft 19A provided upright on an L-shaped movable arm 19, and the movable arm 19 is a shaft having a central portion rotatable on the lower side of the base member 4. 18, and the other end is pulled by the pulling force of the return action spring 17, and in this state, the movable body 16 maintains a space slightly smaller than the diameter of the medal 100 between the fixed side wall 15. is doing.

  Therefore, when the medal 100 pushed out of the delivery rotor 7 reaches between the fixed side wall 15 and the movable body 16, the movable body 16 is pulled by the spring 17 as shown by the dotted line in FIG. When the diameter part of the medal 100 passes, the movable body 16 returns by the pulling force of the spring 17 and is blown off in the direction of the delivery port 14. The bounced medal 100 passes through the detection unit 23 arranged so as to face the sending unit 13 from the fixed side wall 26 side and is sent out from the sending port 14.

  As shown in FIG. 6, the detection unit 23 has an optical sensor configuration including a light emitting unit and a light receiving unit as a detection sensor. In the embodiment, the light emitting unit 24A and the light receiving unit 25A, and the light emitting unit 24B and the light receiving unit 25B are configured with two sets of optical sensors. When the medal 100 passes through the detecting unit 23, the light emitting unit 24A to the light receiving unit 25A. By blocking the light path reaching the light path or the light path reaching the light receiving part 25B from the light emitting part 24B, the number of passing medals 100 is counted by a counting part (not shown) of the control part 61 provided in the electrical equipment part 60. It is a mechanism to do.

  The detection position in the detection unit 23 is a detection at a part out of the diameter of the medal 100. That is, even when the medals 100 sent out from the sending rotor 7 are sent out in succession, each light from the light emitting parts 24A, 24B to the light receiving parts 25A, 25B is able to be detected one by one. The passage is detected not at the diameter part of the medal 100 to be sent, but at a position deviating from the diameter part, that is, at a part shorter than the diameter of the medal 100. That is, as shown in FIG. 7, light from the light emitting portion 24A to the light receiving portion 25A is detected so as to be detected at positions AH and BH close to the fixed side wall 26 from the diameter portion passing through the center CH of the circular medal 100, respectively. A path and a light path from the light emitting unit 24B to the light receiving unit 25B are defined.

  The detection unit 23 may include only one light emitting unit 24A and one light receiving unit 25A. However, the detection unit 23 includes two sets of the light emitting unit 24A and the light receiving unit 25A, and the light emitting unit 24B and the light receiving unit 25B. In this way, the detection accuracy is improved and mischief measures are taken. That is, the detection pulse when the medal 100 passes in the Y1 direction is adopted by the control unit 61 as a count signal, and the detection pulse when the medal 100 is pushed in the direction opposite to the Y1 direction due to mischief is not adopted. This prevents miscounting by mischief. Instead of the method of detecting the detection unit 23 based on such a change in the amount of received light, a change in the amount of electricity (capacitance, induced electromotive force, frequency, etc.) generated by the medal 100 passing, or a change in the amount of magnetic force, etc. It may be one that measures.

  As shown in FIG. 6, the detection unit 23, as shown in FIG. 6, corrects the combination position of the light emitting unit 24 </ b> A and the light receiving unit 25 </ b> A and the combination position of the light emitting unit 24 </ b> B and the light receiving unit 25 </ b> B. 25B are housed in a synthetic resin holder 23A. The synthetic resin holder 23A is substantially U-shaped, and the upper side (upstream side) and the lower side (downstream side) so that the light emitting parts 24A and 24B face the delivery part 13 from the upper side 23A1 which is one side thereof. The lower side 23A2, which is the other side of the synthetic resin holder 23A that opposes the upper side 23A1, is placed on the upper side (upstream side) so that the light receiving units 25A and 25B face the sending unit 13 from below. Built in on the lower (downstream) side. And each light path part from light-emitting part 24A, 24B of synthetic resin holder 23A to light-receiving part 25A, 25B forms the transparent part 23B comprised with the transparent material.

  The synthetic resin holder 23A has a configuration in which the light emitting portions 24A, 24B and the light receiving portions 25A, 25B are embedded by synthetic resin molding, and the synthetic resin holder 23A is configured by a case, and the light emitting portions 24A, 24A, 24B and the light receiving portions 25A and 25B may be housed and sealed. In the present invention, both the case of the structure embedded by synthetic resin molding and the case structure are referred to as a synthetic resin holder 23A.

The parts of the sending unit 13 and the detecting unit 23 are covered with a cover 32 made of synthetic resin. Cover 32 is locked sunk below the engaging portion 33 formed on the upper surface of the base member 4, the other end side is screwed to the base member 4 by screws 34. A distance T2 between the lower surface 32A of the cover 32 and the upper surface 13A of the sending unit 13 is slightly larger than the thickness T0 of the medal 100. Thus, the interval T1 between the fixed side wall 15 and the fixed side wall 26 (interval in the diameter direction of the medal 100) and the interval T2 between the lower surface 32A of the cover 32 and the upper surface 13A of the sending unit 13 (interval in the thickness direction of the medal 100). ) Is the size of the coin-shaped member passage of the delivery unit 13. The outlet of the coin-shaped member passage of the sending unit 13 becomes the sending port 14 of the medal 100.

A restricting member 40 is provided which acts so as to restrict the bridge state and the locked state of the medal 100 flowing into the medals. In particular, the decompression plate 37 and the limiting member 40 extend from the delivery unit 13 side toward the opposite side of the delivery unit 13. This specific configuration is described below.

  In the storage container (hopper) 5P, a coin-shaped member decompression plate 37 extending obliquely downward toward the upper side of the delivery rotor 7 and a lateral space (substantially horizontal direction) extend in a lower space of the decompression plate 37. An elastic coin-like member limiting member 40 is provided. As described above, the storage container (hopper) 5P has a circular opening 5B along the outer periphery of the delivery rotor 7 on the lower side, and the front wall 5F on the delivery unit 13 side so that the upper opening 5A has a substantially rectangular shape. The facing rear wall 5G is formed in a state of obliquely spreading outward from the circular opening 5B, and the remaining two left and right walls 5H and 5M facing from the opening 5B corresponding to the peripheral edge of the delivery rotor 7 It extends substantially vertically. Accordingly, the storage container (hopper) 5P has a container shape in which the lower side is circular and the upper side is rectangular. A delivery rotor 7 is arranged corresponding to the lower surface opening 5B.

  The decompression plate 37 is located on the delivery unit 13 side in the storage container (hopper) 5P, and is fixed to the front wall 5F and the left and right walls 5H and 5M with screws 38 with a width extending over the left and right walls 5H and 5M. It extends obliquely downward from the wall 5F toward the upper side of the delivery rotor 7, and as a preferred form, the delivery position exceeds the rotational axis 9 which is the approximate rotation center of the delivery rotor 7 or the rotational axis 9 of this rotation center CL. It extends obliquely downward to a position above the rotor 7. In order to prevent the medal 100 sliding on the decompression plate 37 from concentrating on one part of the delivery rotor 7 and falling, the medal 100 sliding on the decompression plate 37 is formed by making the tip of the decompression plate 37 into an arc 37P. Is not concentrated in the center of the decompression plate 37 and easily falls from the left and right, so that the load distribution on the delivery rotor 7 can be achieved. The left-right width of the decompression plate 37 is narrow at the left and right base points of the tip arcuate shape 37P, and a gap 37S is formed there. The gap 37S is determined to have a dimension in which 1 to 3 medals 100 are not overlapped and locked.

  Further, the coin-like member limiting member 40 is tapered and elastic, and extends in the lateral direction (substantially horizontal direction) from the front wall 5F on the delivery unit 13 side toward the space between the decompression plate 37 and the delivery rotor 7. As a preferred form, the base portion fixed to the front wall 5F with a screw 44 is constituted by a cylindrical metal base member 41 fixed to the wall on the delivery portion side, and the tip portion is substantially conical. A synthetic resin-made tip member 42 is formed, and a portion between the base member 41 and the tip member 42 is constituted by a coil spring 43 extending from the base member 41 to the tip member 42. The distal end 42P of the distal end member 42 extends in the lateral direction in a substantially horizontal state up to a position above the rotation shaft 9 that is a substantial rotation center CL of the delivery rotor 7 or an upper position in the vicinity thereof, and the decompression plate 37 in a plan view. It is in the state where it does not come out from the tip of.

The base member 41 is formed with an annular groove 41A into which the base of the coil spring 43 is fitted, and a large-diameter portion 41B with which the base side of the coil spring 43 expands the coil diameter and elastically engages the tip of the annular groove 41A. The base portion of the coil spring 43 is firmly held by the base member 41. The tip member 42 has a conical portion whose base diameter is considerably larger than the diameter of the coil spring 43. The tip member 42 has an annular groove 42A into which the tip of the coil spring 43 is fitted, and a rear side of the annular groove 42A. A large-diameter portion 42B is formed in which the distal end side of the coil spring 43 is elastically engaged by enlarging the coil diameter, whereby the distal end member 42 and the distal end portion of the coil spring 43 are firmly coupled. In the base member 41, the screw portion 44A of the screw 44 is screwed into a screw hole 41C formed in the central axis, and the base member 41 is fixed to the front wall 5F and held in a substantially horizontal state.

  A second hopper 5P2 is disposed on the storage container (hopper) 5P in communication with the rectangular upper opening 5A in the storage container (hopper) 5P. The medal 100 is replenished. The replenished medal 100 falls directly to the rear wall 5G of the storage container (hopper) 5P, and collides with the one that moves toward the sending rotor 7 along its inclination, and the pressure reducing plate 37. Some move along the slope. In this way, the medal 100 is accommodated in the storage container (hopper) 5P and the second hopper 5P2.

  Since the decompression plate 37 exists above the delivery rotor 7, the pressure exerted on the delivery rotor 7 by the load of the medal 100 in the storage container (hopper) 5P and the second hopper 5P2 is attenuated by the decompression plate 37. The load on the delivery rotor 7 is reduced. On the other hand, the movement of the medal 100 in the storage container (hopper) 5P is complicated, and if there is a medal 100 that stands up by the rotation of the sending rotor 7, it moves by sliding on the rear wall 5G of the storage container (hopper) 5P. When the medal 100 or the like presses the medal 100 between the sending rotor 7 and the decompression plate 37 and the pressure is large, the medals 100 are in a bridge state or a locked state. If it becomes such a state, the movement of the medal 100 to each separation hole 10 of the sending rotor 7 stops, and good medal sending cannot be performed.

  However, due to the presence of the coin-shaped member limiting member 40, the medal 100 that has entered between the delivery rotor 7 and the decompression plate 37 collides with the conical shape of the tip member 42 of the taper limiting member 40, and along that shape. Since the tip member 42 is deflected to the periphery and moves in the vertical, horizontal, and diagonal directions against the elastic force of the coil spring 43, the medal 100 above the delivery rotor 7 constantly moves with the rotation of the delivery rotor 7. This prevents the medal 100 from being in a bridge state or a locked state. Similarly, the medal 100 that is in an upright state due to the rotation of the delivery rotor 7 cannot be maintained in the upright state due to the movement of the restricting member 40 or the deflection movement along the conical shape of the tip member 42, and the obstacle caused by the upright state. Is also resolved.

  The restricting member 40 maintains a projecting posture in a substantially horizontal state substantially parallel to the delivery rotor 7 so that the tip is located in the space between the delivery rotor 7 and the decompression plate 37. Even if 42 is deflected, the elastic force of the coil spring 43 is set so that it always returns to the substantially horizontal protruding posture position. For this reason, when the tip member 42 is deflected considerably large, the medal 100 is moved when the tip member 42 is restored by the elastic force of the coil spring 43, so that the medal 100 can be prevented from being bridged or locked. Acts to be.

  As described above, the storage container (hopper) 5P is provided with the decompression plate 37 and the restricting member 40 extending from the sending part 13 side to the opposite side of the sending part 13, so that the medal on the sending part 13 side is provided. The 100 bridge state and the lock state can be satisfactorily eliminated, and the medal delivery is good.

  In FIG. 12, as another form of the coin-shaped member feeding device 2, a coin-like shape in which three separation holes 10 are formed in the sending rotor 7 at equal angular intervals so as to send the medal 100 having a diameter of 30 mm. The top perspective view of a member delivery device is shown. Since the configuration and the operation function are the same as described above, the above description is used, and the same reference numerals are given to the same functional parts.

  The corner portion of the front wall 5F of the storage container (hopper) 5P is provided with a medal remaining prevention member 46 composed of a coil spring extending so as to approach the separation hole 10 of the delivery rotor 7 where the tip 46P rotates from above. Yes. This medal remaining prevention member 46 acts so that the medal 100 receives resistance as the delivery rotor 7 rotates, and enters the medal separation hole 10 one by one in a horizontal state where the medal 100 falls sideways.
