Description

  The present invention relates to a disk body ejecting apparatus for ejecting a disk body.

  In a game shop where a pachislot machine or the like is installed, a medal counting machine for counting medals acquired by the player with the pachislot machine is installed.

  In this medal counting machine, the medal obtained by the player is inserted into the hopper of the medal counting machine, so that the medal is received on the rotating disk on the lower side of the hopper, and the rotating disk is rotated. The medal is moved to the outer periphery of the rotating disk using the frictional force and centrifugal force, and the medal is used as the peripheral wall member while restricting the outward movement of the medal with the peripheral wall member arranged opposite to the periphery of the rotating disk. The gate members that are part of the peripheral wall member and are arranged opposite to the upper surface of the rotating disk are passed through the medals on the rotating disk one by one in the thickness direction one by one. The medals that pass one by one are counted.

  In such a medal counting machine configuration, the medal is caught between the rotating disk and the gate member, and the medal is bitten into the lower part of the gate member, while the medal is partially overlapped with the following medal. There is a case where a so-called jam jammed so-called jam occurs in which the resistance between the medal and the rotating disk increases and the rotating disk stops.

  Conventionally, in order to prevent the occurrence of clogging of medals due to the biting of medals, one end of the gate member corresponding to the upstream side in the forward rotation direction of the rotating disk is supported by a swing shaft, and the other end side of the gate member is rotated. It is supported so that it can move between a restricting position that allows a single medal to pass through in the thickness direction with respect to the upper surface of the disk and an open position that is further away from the upper surface of the rotating disk than the restricting position. There is a configuration in which the gate member is urged to a restricted position by a spring.

When the rotating disk rotates normally, medals pass one by one in the thickness direction below the gate member by the gate member biased to the restriction position. On the other hand, when a medal is caught between the gate member and the rotating disk, the gate member rises against the bias by the spring, and the engraved medal increases the biting strength together with the rotating disk. It relaxes and prevents medal biting (see, for example, Patent Document 1).
Japanese Patent Laid-Open No. 2001-31757 (page 4-6, FIG. 1-4)

  However, it is necessary to provide the gate member so as to be able to swing, or to provide a spring or the like for biasing the gate member to the restricting position, and there is a problem that the configuration becomes complicated, space is required, and cost is increased.

  Further, if the medal bite between the gate member and the rotating disk is too strong, the bite may not be released.

  The present invention has been made in view of such points, and an object thereof is to provide a disk body ejecting apparatus that can easily prevent the disk body from being bitten under the gate member with a simple configuration. And

  The disk body ejecting device according to claim 1 is a rotating disk that receives the disk body, a rotating disk drive mechanism that rotates the rotating disk, a peripheral wall member that is arranged around the rotating disk, and the peripheral wall member And a gate member provided with a gap that allows passage of only one disk in the thickness direction with respect to the upper surface of the rotating disk, and the rotation at a position below the periphery of the gate member. And a groove provided below the upper surface of the disk.

  The disc body ejecting device according to claim 2 is the disc body ejecting device according to claim 1, wherein the width of the groove portion corresponding to the radial direction of the rotating disk is 1/5 to 1 of the diameter of the disc body. / 10 range.

  The disc body ejecting device according to claim 3 is the disc body ejecting device according to claim 1 or 2, wherein the outer wall surface of the groove is a substantially vertical surface.

  The disc body ejecting device according to claim 4 is the disc body ejecting device according to any one of claims 1 to 3, wherein the groove is provided on the upper surface of the rotating disk along the circumferential direction. is there.

  According to the disk body ejecting device of the first aspect, since the groove portion is provided below the upper surface of the rotating disk at the lower peripheral position of the gate member, the disk body biting under the gate member enters the groove portion. By this, the inclination of the disk body is larger than when there is no groove, and it is possible to prevent the subsequent disk body from entering the wedge body strongly under this disk body. Biting of the disk body on the lower side can be made difficult to occur.

  According to the disk body ejecting device according to claim 2, in addition to the effect of the disk body ejecting device according to claim 1, the width of the groove corresponding to the radial direction of the rotating disk is set to the diameter of the disk body. By setting it as the range of 1/5-1/10, compared with the other than that range, the normal delivery of the disc body in the lower side of a gate member is not prevented.

  According to the disk body ejecting device according to claim 3, in addition to the effect of the disk body ejecting device according to claim 1 or 2, the outer wall surface of the groove portion is formed into a substantially vertical surface, thereby It is possible to prevent the intruding disc body from getting over the groove and biting under the gate member.

  According to the disc body ejecting device of claim 4, in addition to the effect of the disc body ejecting device according to any one of claims 1 to 3, the groove portion is provided on the upper surface of the rotating disc along the circumferential direction. This makes it difficult for the disc body to bite between the gate member and the rotating disk.

In the rotating disk 32, the medal M is placed on the upper surface of the rotating disk 32 in a plane direction, and the rotating disk 32 is rotated forward at high speed, whereby the rotating disk 32 is rotated by the frictional force and centrifugal force between the medal M and the rotating disk 32. The medal M on 32 is moved to the periphery of the rotating disk 32. A cap 41 that guides the medal M to the periphery of the rotating disk 32 is disposed at the center of the rotating disk 32.

  Further, the rotating disk drive mechanism 33 rotates the rotating disk 32 in the medal feeding direction (forward rotation direction) F when the medal is paid out, and the medal clogging releasing direction opposite to the medal feeding direction during the medal clogging releasing operation. (Reverse direction) Rotate to R. The rotating disk drive mechanism 33 includes a rotating disk motor 43, and a belt 46 is stretched between a driving pulley 44 that is rotated by the rotating disk motor 43 and a driven pulley 45 that is connected to the rotating shaft of the rotating disk 32. Then, the driving force of the rotating disk motor 43 is transmitted to the rotating disk 32. A rotation detecting means 47 (see FIG. 11) for detecting the rotation of the rotating disk 32 is provided.

  The guide body 34 includes a substrate 49 and a cylindrical guide portion 50 attached to the substrate 49 and made of, for example, rubber and having a diameter smaller than that of the rotating disk 32. The gap between the cylindrical guide portion 50 and the upper surface of the rotating disk 32 is smaller than the diameter of the medal M so that the medal M moves in parallel to the rotating disk 32 from the center side of the rotating disk 32 to the peripheral part by an appropriate amount. Is set to

  In addition, the peripheral wall member 35 is a cylindrical wall disposed facing the periphery of the rotating disk 32 and restricts the medals M on the rotating disk 32 from going out, and is in a random state. The medals M are aligned by moving along the peripheral wall member 35. An opening 52 is formed in the peripheral wall member 35 so as to correspond to the payout position of the medal M from the rotary disk 32. A gate member 36 is integrally coupled to both ends of the peripheral wall member 35 so as to close the opening 52, and the peripheral wall member 35 including the gate member 36 is formed in a highly rigid cylindrical shape.

  A plurality of fixing members 53 are attached around the peripheral wall member 35, and are fixed to the base 31 with fixing screws 54 via the fixing members 53. Among the plurality of fixing members 53, the fixing member 53 in the vicinity of the gate member 36, in particular, the fixing member 53 located in the vicinity of the gate member 36 in the upstream in the rotation direction of the medal feeding direction F is the base 31. Not fixed to. Therefore, the peripheral wall member 35 is formed with a movement allowance portion 55 that is allowed to move in the vertical direction at a position upstream of the gate member 36 in the rotation direction of the medal payout direction F. Corresponding to the position of the movement allowance portion 55, there is a restriction pin 56 as a peripheral wall member restriction portion that engages and positions the inner surface and the outer surface of the movement allowance portion 55 when the gate member 36 is lowered to a predetermined restriction position. Is provided.

  The gate member 36 is formed of a flat plate material, and is integrally formed with a plurality of coupling screws 58 at both ends of the peripheral wall member 35 so as to close the opening 52 of the peripheral wall member 35 at an intermediate portion of the gate member 36. Are combined. A gate portion 59 is formed in the middle portion of the gate member 36 so as to be opposed to the upper side of the rotating disk 32, and a gap 60 is formed between the lower edge of the gate portion 59 and the upper surface of the rotating disk 32. . The gap 60 is set and fixed to a dimension that allows passage of only one medal M in the thickness direction at a normal time such as when a medal is paid out. A substantially L-shaped contact plate 61 is coupled by a coupling screw 62 at a position on the inner surface side of the gate portion 59 on the upstream side in the rotation direction in the medal feeding direction F. The lower edge of the abutting plate 61 is provided at the same height as the lower edge of the gate portion 59.

  An end portion of the gate member 36 corresponding to the upstream side in the rotation direction of the medal feeding direction F is extended, and a concave cam groove 64 is formed at the edge of the end portion.

  The gate member support mechanism 37 includes a peripheral wall member 35 to which the gate member 36 is coupled, a fixing member 53 that fixes the peripheral wall member 35 to the base 31, and the both ends of the peripheral wall member 35 with respect to the fixing member 53. The gate member 36 is supported so as to be movable in the up and down direction integrally with the peripheral wall member 35 within a range in which can be displaced. Then, when one end of the gate member 36 corresponding to the downstream side in the rotation direction of the medal feeding direction F is set as the other end and the other end is driven up and down, in the vicinity of one end of the gate member 36 The vicinity of the fixing member 53 that fixes the peripheral wall member 35 is supported as a fulcrum, that is, the other end of the gate member 36 is supported so as to be swingable in the vertical direction with the one end of the gate member 36 as a fulcrum.

  The gate member drive mechanism 38 has a cam 66 that engages with the cam groove 64 at the other end of the gate member 36. The cam 66 rotates eccentrically with respect to a cam shaft 67 that is rotatably provided at a fixed position, and the gap 60 that allows the passage of only one medal M in the thickness direction with respect to the upper surface of the rotating disk 32 is allowed for the gate member 36. Is swung around the one end portion side of the gate member 36 as a fulcrum between the restriction position that forms the distance between the restriction position and the open position away from the upper surface of the rotary disk 32 from the restriction position. At this time, as shown in FIG. 7, at the restriction position of the gate member 36, the lower edge of the gate member 36 is parallel to the upper surface of the rotary disk 32, and as shown in FIG. Then, the gate member 36 swings so that the gap 60 between the gate member 36 and the rotary disk 32 widens in the medal clogging release direction (reverse direction) R of the rotary disk 32. The rising amount of the gate member 36 is preferably about 1 to 2 mm at the largest place.

  The cam shaft 67 is rotationally driven by a cam motor 68 as drive means. The cam shaft 67 is provided with gate member position detecting means 69 for detecting a rotation position corresponding to the restriction position of the gate member 36 and a rotation position corresponding to the opening position of the gate member 36, respectively. The gate member position detecting means 69 includes a detection plate 70 attached to the cam shaft 67, and a position detection sensor 71 having a light projecting portion and a light receiving portion arranged on both sides of the detection plate 70. The notch 72 is provided corresponding to the restriction position and the opening position of the gate member 36, and the restriction position and the opening position of the gate member 36 are detected when the position detection sensor 71 is translucent in each of the notches 72. To do.

  In addition, on the lower side of the rotating disk 32 corresponding to the position of the gate member 36, a restricting roller 74 as a restricting member for restricting the lowering of the rotating disk 32 is rotatably arranged corresponding to the rotating direction of the rotating disk 32. It is installed. The dimension L that restricts the lowering of the rotary disk 32 by the restriction roller 74 is within a range of dimensions that can automatically release clogged medals by moving the gate member 36 to the open position.

  Next, as shown in FIGS. 1 and 3, in order to prevent the medal M as a disc body from biting below the gate member 36, the groove portion 76 into which the leading end of the medal M to be bitten intrudes enters. Is provided on the upper surface of the rotating disk 32 over the entire circumference thereof.

  The position of the groove 76 is not sufficient to prevent the bite member 36 from being caught even if it is too far away from the lower side of the gate member 36 to the inner diameter side of the rotary disk 32 or outward from the outer surface of the gate member 36. A lower peripheral position on the outer side of the gate member 36 that is the vicinity where the tip of the medal M passes on the lower side is preferable.

  The depth h of the groove 76 is at least half of the thickness of the medal M, and is preferably about half to one. If it is smaller than half the thickness of the medal M, the amount of intrusion at the tip of the medal M to be bitten is small and the biting prevention effect is not sufficient.

  The width w of the groove 76 is preferably in the range of 1/5 to 1/10 of the diameter of the medal M. If the diameter is larger than 1/5 of the diameter of the medal M, the medal M to be normally paid out becomes unstable, and the side effect that the feeding efficiency is lowered by entering the groove unnecessarily easily occurs. If it is smaller than 1/10, the tip of the medal M to be bitten may not easily enter. Therefore, the width w of the groove part 76 is about several mm, for example, about 4 mm is preferable.

  The outer wall surface 76a of the groove portion 76 is a substantially vertical surface so that the tip of the medal M to be bite into the groove portion 76 does not get over the groove portion 76 when coming into contact with the outer wall surface 76a. Is preferred.

  Next, as shown in FIG. 11, the control unit 81 that controls the medal counter 11 includes a counting unit 25 that counts medals M, a rotation detecting unit 47 of the rotating disk 32, and a gate member position detecting unit 69 of the gate member 36. Etc. are input to control the rotary disk motor 43 of the rotary disk drive mechanism 33, the cam motor 68 of the gate member drive mechanism 38, the notification means 82, the display panel 17, and the like.

  The notification means 82 includes a light emitting unit 18 of the medal counting machine main body 12 that emits light, a speaker that emits sound, a buzzer, and the like.

  Then, when the rotation detecting means 47 detects that the rotation of the rotating disk 32 is stopped while the rotating disk 32 is being driven, the control unit 81 causes the medal M to be clogged between the rotating disk 32 and the gate member 36. If the rotation detecting means 47 detects the reverse rotation of the rotating disk 32 during the clogging releasing operation, the clogging of the medal M between the rotating disk 32 and the gate member 36 is released. It has a function of clogging release detecting means 84 for detecting as a trap.

  Further, when the clogging detecting means 83 detects clogging of the medal M, the control unit 81 moves the gate member 36 to the open position by the gate member driving mechanism 38 and reverses the rotating disk 32 by the rotating disk driving mechanism 33. When the clogging release detection means 84 detects the clogging release of the medal M within a predetermined time after reversing the rotating disk 32, the reversing of the rotating disk 32 by the rotating disk driving mechanism 33 is stopped and the gate member driving mechanism 38 is stopped. If the clogging of the medal M is not released even by the medal clogging release operation, the medal clogging releasing operation is stopped and the notification means 82 is used to notify the gate member 36. is doing.

  In addition, the control unit 81 has a storage unit 86 that stores the count value obtained by the counting unit 25.

  Next, the operation of the present embodiment will be described.

  First, normal processing will be described. In the normal process, as shown in FIG. 7, the gate member 36 is positioned at the restriction position, and only one medal M in the thickness direction is allowed to pass between the lower edge of the gate member 36 and the upper surface of the rotary disk 32. A gap 60 is formed. The gate member 36 is fixed at the restricting position by the cam groove 64 engaging with the cam 66, and the gap 60 between the lower edge of the gate member 36 and the upper surface of the rotary disk 32 is kept constant. ing.

  When a player places a medal M into the hopper 21 and instructs the display panel 17 to start counting, the medal counting operation is started. The instruction to start counting may be such that a medal counting operation is automatically started upon detection by a sensor or the like that a medal M has been inserted on the rotating disk 32 through the hopper 21.

  When the medal counting operation starts, the rotating disk 32 rotates in the medal feeding direction F, and the medal M on the rotating disk 32 moves to the periphery of the rotating disk 32 by the frictional force and centrifugal force between the medal M and the rotating disk 32. To do. At this time, the medal M parallel to the rotating disk 32 is moved to the peripheral part of the rotating disk 32 by an appropriate amount by the guide body 34.

  The medals M that have moved to the periphery of the rotating disk 32 are in contact with the peripheral wall member 35 and are restricted from moving outward, and move along the peripheral wall member 35 while being relatively aligned from a random state. Become.

  When the medal M moving along the peripheral wall member 35 on the rotating disk 32 reaches the position of the gate member 36, one medal M placed in the thickness direction parallel to the rotating disk 32 enters the lower side of the gate member 36. And pass to the passage portion 23. The medal M and the like that overlap the upper side of the medal M that enters the lower side of the gate member 36 abuts on the gate member 36 and does not enter the lower side of the gate member 36, but passes through the position of the gate member 36. Move on the rotating disk 32. In this way, the medals M on the rotating disk 32 are passed through the passage portion 23 from the lower side of the gate member 36 one by one in the thickness direction and are fed out.

  The medals M that are fed out one by one to the passage unit 23 are transported by the transport belt 24, counted by the counting unit 25, and sent to the outside of the medal counter main body 12 to be collected.

  The player or the like confirms the state of the medal M in the hopper 21 and determines that the counting is finished. When the player or the like instructs the display panel 17 to finish counting, the medal counting operation is stopped and the display panel 17 Display counting results. The counting end instruction may automatically detect that the medal M has run out of the rotary disk 32 and the passage portion 23, automatically determine the end of counting, stop the medal counting operation, and display the counting result. .

  Next, the operation of the groove 76 provided in the rotating disk 32 will be described with reference to FIGS. 1 and 3 show the configuration of the present embodiment in which the groove portion 76 is provided in the rotating disk 32, and FIG. 2 shows a comparative example in the case where the groove portion 76 is not provided in the rotating disk 32. In FIG. 2, the same reference numerals as those used in this embodiment are given.

  As shown in FIG. 2, when the tip of the medal M1 that partially overlaps the succeeding medal M2 or the like enters the lower side of the gate member 36 on the rotary disk 32, the tip of the medal M1 There is a bite generation region S which is a region where the portions abut and is likely to bite.

  When there is no groove 76 in the biting occurrence region S on the rotating disc 32, the tip of the medal M1 to be bitten contacts the upper surface of the rotating disc 32 that is the biting occurrence region S on the rotating disc 32. The medal M1 has a small inclination (inclination angle α1 with respect to the upper surface of the rotating disk 32), and the subsequent medal M2 and the like enter the lower side of the medal M1 strongly in a wedge shape, so that the medal M1 is likely to be bitten.

  During the rotation of the rotating disk 32, a state in which the tip of the medal M enters the biting generation area S and bites into it frequently occurs. Among the medals M that become the biting reserve army whose tip portion has entered the biting generation region S, the rotating disc when the resistance force of a part of the medals M that are bitten particularly strong overcomes the rotating force of the rotating disc 32 It will lead to 32 stops.

  As shown in FIGS. 1 and 3, by providing the rotary disk 32 with the groove 76, the tip of the medal M1 to be caught enters the groove 76 and comes into contact with the outer wall surface 76a. Since it does not advance, the rate at which the tip of the medal M1 to be bitten reaches the biting generation area S outside the groove 76 is reduced.

  When the medal M1 to be bitten is sandwiched between the gate member 36 and the rotating disk 32, the tip of the medal M1 enters the groove 76 of the rotating disk 32, so that the medal M1 is in contact with the gate member 36 and the rotating disk. It is possible to have a clearance for being caught between 32 and this can ease the biting force of the medal M1.

  Moreover, when the tip of the medal M1 to be bitten enters the groove 76 into the rotating disk 32, the inclination of the medal M1 (inclination angle α2 with respect to the upper surface of the rotating disk 32) is the inclination when the groove 76 is not present (inclination angle α1). ) Is larger than Therefore, the pushing resistance of the medal M1 to be bitten increases for the subsequent medal M2, etc., and the subsequent medal M2 etc. is hard to enter the wedge shape under the medal M1 to be bitten, and the biting force of the medal M1 is a groove portion. Smaller than without 76. Further, the inclination of the medal M1 to be bitten increases, and the allowable amount of the number of subsequent medals M sandwiched between the medal M1 and the rotating disk 32 also increases the difficulty of biting.

  In this way, by replacing a part of the biting generation region S when there is no groove 76 with the groove 76, the biting generation region S can be narrowed, and the biting of the medal M under the gate member 36 itself can be reduced. Can hardly occur.

  It is to be noted that the provision of the groove 76 in the rotating disk 32 makes it difficult for the medal M to bite under the gate member 36 itself, but the medal M strongly bites under the gate member 36 to rotate the rotating disk 32. When a medal jam that stops is occurred, the medal jam release operation is automatically performed.

  Next, the medal jam release operation will be described.

  During the medal counting, the medal M partially overlapped with the succeeding medal M tries to enter the lower side of the gate member 36, and the medal M bites between the gate member 36 and the rotating disk 32. Since the position of the gate member 36 does not change, the rotating disk 32 is pushed down with the bitten medal M, and when the amount of pressing down increases, the resistance between the bited medal M and the rotating disk 32 increases, and the rotating disk 32 becomes Stopping, so-called jammed jam, which is called jamming, occurs.

  If rotation of the rotating disk 32 is no longer detected by the rotation detection means 47 even though the medals are being counted, the clogging detection means 83 automatically determines that a medal clogging has occurred and starts the clogging release operation. To do.

  In the clogging release operation, the drive control of the rotating disk 32 in the medal feeding direction F is stopped, the cam 66 is rotated by driving the cam motor 68, and the gate member 36 is forcibly raised from the restricted position to the open position. The biting of the medal M is eased. At this time, as shown in FIG. 5, the gate member 36 swings so that the gap 60 between the gate member 36 and the rotating disk 32 widens in the medal clogging release direction (reverse direction) R of the rotating disk 32.

  Subsequently, by rotating the rotating disc 32 in the medal releasing direction R, the jammed medal M moves from the lower side of the gate member 36 to the inside of the rotating disc 32, and the medal jam can be released.

  Accordingly, when the clogging of the medal M is detected by the clogging detecting means 83, the gate member 36 is raised to an open position where the gap 60 with the rotating disk 32 is widened to ease the biting of the medal M, and the rotating disk 32 is moved in the medal releasing direction. By reversing to R, the rotating disk 32 can be reversed in the medal release direction R even when the medal M is strongly bitten, and the medal jam can be reliably released automatically. In particular, since the gate member 36 swings so that the gap 60 between the gate member 36 and the rotating disk 32 widens in the medal clogging release direction (reverse direction) R of the rotating disk 32, the clogged medal M is surely removed. Can be automatically canceled.

  At this time, the rotary disk 32 is pushed down by the biting of the medal M, but the lowering amount of the rotary disk 32 is restricted by the restriction roller 74 within a range of dimensions that can be automatically released by moving the gate member 36 to the open position. Automatic release of clogged medals can be ensured.

  Then, if the rotation detecting means 47 detects the reverse rotation of the rotating disk 32 within a predetermined time after the reverse rotation control of the rotating disk 32, it is determined that the clogging release detecting means 84 has released the clogged medal. When the release of the medal jam is detected, the cam 66 is rotated by driving the cam motor 68 while the rotating disk 32 is reversed, and the gate member 36 is forcibly lowered from the open position to the restricted position. Thereafter, the reverse rotation of the rotating disk 32 is stopped to stop the medal jam release operation. By controlling in this way, it is possible to prevent a new medal clogging due to the reverse rotation of the rotating disk 32.

  Since the cam 66 is rotated by driving the cam motor 68 and the gate member 36 is forcibly lowered from the open position to the restricting position, the reliability of the separation operation of one medal M by the gate member 36 after the medal clogging is released. Can be reliably reproduced.

  In particular, the gate member 36 is coupled to the peripheral wall member 35, and the peripheral wall member 35 can move integrally with the movement of the gate member 36 to the restriction position and the open position, so that the rigidity of the gate member 36 and the peripheral wall member 35 is increased. Dimensional accuracy can be improved.

  In addition, with the one end of the gate member 36 corresponding to the rotation direction downstream side of the medal feeding direction F of the rotating disk 32 as a fulcrum, the other end of the gate member 36 is supported so as to be swingable in the vertical direction. The gate member 36 is used to release the clogged medal because the cam 66 that engages the cam groove 64 at the other end of the 36 is rotated to forcibly move the gate member 36 between the restriction position and the open position. Even if 36 is moved, the gate member 36 can be reliably returned to the original restriction position, and the gate member 36 can be prevented from moving at the original restriction position in the normal state, and the reliability thereof can be increased.

  Thereafter, the rotating disk 32 is rotated in the medal feeding direction F, and the medal counting operation is resumed. The resumption of the medal counting operation may be automatically resumed, or a player or the like may instruct the restart after confirming the state of the medal M in the hopper 21.

  In addition, if the rotation detecting means 47 does not detect the reverse rotation of the rotary disk 32 within a predetermined time after the reverse rotation control of the rotary disk 32, the rotary disk 32 is temporarily stopped and then rotated again. It is also possible to monitor whether or not the rotating disk 32 reverses by repeating the reverse rotation control and the stop of 32.

  Further, for example, in a situation where the medal M is biting in such a way that it is impossible to release the jammed jam by the automatic release function, the reverse rotation of the rotary disk 32 is detected within a predetermined time after the reverse rotation control of the rotary disk 32. If it is not detected by 47, or if the reverse rotation of the rotating disk 32 is not detected by the rotation detecting means 47 even if the reverse rotation control and stop of the rotating disk 32 are repeated a predetermined number of times, the reverse rotation control of the rotating disk 32 is stopped and the medal jam release operation is stopped. Is stopped, and an alarm is issued or displayed on the display panel 17, for example. Thereby, the attendant of the game store that has received the notification can take a countermeasure such as manual release of the clogged medal.

  The medal counter 11 is not limited to a type having two hoppers 21 and may be a type having one or three hoppers 21.

  Further, the groove 76 for preventing the medal M from being bitten is provided along the circumferential direction on the upper surface of the rotating disk 32, so that the biting of the medal M between the gate member 36 and the rotating disk 32 itself. However, it may be provided in the passage portion 23 outside the rotating disk 32, or may be constituted by a gap between the rotating disk 32 and the passage portion 23. In this case, the groove 76 only needs to be provided at a lower position around the periphery of the gate member 36.

  In addition to the medal M of the amusement store, the disc body can be applied to a disc shape such as a coin or an IC coin.
