In the upstream side bottom members 90 , 90 , the game medium B flows down toward the left and right outer sides in the width direction Dw without dropping from the plurality of separation holes H, and reaches the downstream side bottom members 92 , 92 . Then, the game medium B flows down on the downstream side bottom members 92, 92 and flows into the upper island inner tanks 38, 38 (see arrow Y7a).

On the other hand, in the upstream bottom members 90, 90, the abrasive K drops from the separation hole H (indicated by arrow Y6a). Note that the abrasive material K dropped from the separation hole H and recovered is washed by a washing unit (not shown). The abrasive K after cleaning is transported to the upstream end of the screw member 33 and supplied to the lifting passage 32a. In other words, it is supplied again for polishing the game media B. Here, the cleaning liquid used in the cleaning section contains an antistatic agent (antistatic agent) as an additive. In other words, the static electricity suppressing agent contained in the cleaning agent used when cleaning the abrasive K is an example of static electricity removing means.

Further, from each blowing port 97 of the blowing nozzle 96, gas is blown against the game medium B and the abrasive K that have flowed into the upstream bottom members 90,90. Also, the operation of the vibration motor 98 vibrates the upstream bottom members 90 , 90 . Therefore, the abrasive material K mixed with the game media B is shaken downward and easily separated from the game media B. In addition, dirt removed from the game medium B by the rotation of the screw member 33 can be easily separated.

Next, the shutter mechanism 80 provided in the first delivery section 69A and the second delivery section 69B will be described. The shutter mechanisms 80 provided in the sending units 69A and 69B have the same configuration. The shutter mechanism 80 is an example of a circulation control mechanism that controls the circulation of game media in the passage.

As shown in FIGS. 11 to 13, the shutter mechanism 80 includes a rectangular box-shaped frame 81 extending in the vertical direction, a motor 83, a shutter 85 which is an example of a flow control member displaced by the motor 83, and a guide portion 89 that guides the displacement of the shutter 85 . The shutter mechanism 80 will be described in detail below.

The frame 81 is fixed to the island trough 49B or the housing 39 using fixing members (not shown) such as screws and bolts. A passage hole 81a is formed in the upper portion of the frame 81 so as to pass through the frame 81 along the depth direction Dd. That is, the upper portion of the frame 81 has a passage hole 81a, and constitutes a gate portion 82 through which the game media B can pass.

The gate portion 82 has a bottom plate 82a extending along the depth direction Dd and side walls 82b, 82b erected at both ends of the bottom plate 82a in the width direction Dw. The side walls 82b, 82b face each other in the width direction Dw and form side wall surfaces of the passage hole 81a. The bottom plate 82a forms the bottom surface of the passage hole 81a. That is, the bottom plate 82a forms part of the bottom surface TSa of the island passage TS, which is an example of the passage. The game medium B flowing out from the supply port 38c of the upper island inner tank 38 can pass through the gate portion 82 when flowing down the island crossing trough 49B.

The bottom plate 82a is formed with a plurality of first insertion holes 82c passing through the bottom plate 82a along the height direction Dh. The plurality of first insertion holes 82c are arranged along the width direction Dw. There are eight first insertion holes 82c in this embodiment, all of which are round holes. The diameter of the first insertion hole 82c is smaller than the diameter of the game ball Bp and smaller than the diameter of the game medal Bm. That is, the plurality of first insertion holes 82c are sized such that the game medium B cannot pass through.

The shutter 85 includes a rectangular box-shaped base portion 86 extending along the width direction Dw, and a plurality of round bar-shaped shutter pins 87 extending upward from the upper surface of the base portion 86 . . The plurality of shutter pins 87 are arranged along the width direction Dw (the width direction of the island passage TS). In one example of the present embodiment, there are ten shutter pins 87, all of which are rod-shaped portions (rod-shaped portions). The interval between the plurality of shutter pins 87 along the width direction Dw is narrower than the diameter of the game ball Bp and narrower than the diameter of the game medal Bm. The plurality of shutter pins 87 are narrower at their distal ends than at their proximal ends. The tip portions of the plurality of shutter pins 87 are all conical. That is, each of the plurality of shutter pins 87 has a sharp shape.

Among the plurality of shutter pins 87, the shutter pins 87 at both ends in the width direction Dw (hereinafter referred to as first shutter pins 87) are relatively smaller than the other shutter pins 87 (hereinafter referred to as second shutter pins 87). long. That is, when the base portion 86 is used as a reference, the tips of the shutter pins 87 at both ends are positioned higher than the tips of the other shutter pins 87 . Also, the shutter pins 87 at both ends have a larger diameter (that is, thicker) than the other shutter pins 87 . In this embodiment, the shutter pins 87 at both ends are an example of the first rod-shaped portion, and the other shutter pins 87 are an example of the second rod-shaped portion.

As shown in FIG. 11, the shutter 85 can be displaced between a first position PA and a second position PB by a motor 83. As shown in FIG. The first position PA is a position where a portion of the tip side of the second shutter pin 87 protrudes into the island passage TS from the first insertion hole 82c, and restricts the circulation of the game media B in the island passage TS. The second position PB is a position at which the second shutter pin 87 does not protrude from the first insertion hole 82c into the island passage TS and allows the game medium B to flow within the island passage TS. When the shutter 85 is at the first position PA, one second shutter pin 87 is inserted into each of the first insertion holes 82c. In a plan view, the first shutter pins 87 are positioned on the opposite side (outside) of the island passage TS across the side wall 82b.

The diameter of the first insertion hole 82 c is sufficiently larger than the diameter of the second shutter pin 87 . Therefore, the second shutter pin 87 is prevented from coming into contact with the edge of the first insertion hole 82c as the shutter 85 is displaced. On the other hand, since the distance (clearance) between the second shutter pin 87 and the edge of the first insertion hole 82c is increased, abrasive material K, dust, dirt, and game media B are scraped off from this portion. Foreign matter such as dirt may fall.

The guide portion 89 is provided below the gate portion 82 in the frame 81 . The guide portion 89 includes a planar first side wall 89a orthogonal to the depth direction Dd, and a second side wall 89a extending from both ends of the first side wall 89a in the width direction Dw toward the side where the shutter 85 is disposed. side walls 89b, 89b. When the motor 83 operates, the shutter 85 moves along the inner surfaces of the first side wall 89a and the second side wall 89b.

That is, the shutter 85 is displaced along the guide surface 89c, which is the inner surface of the side walls 89a and 89b on the base portion 86 side. The guide surface 89c extends along a direction crossing the bottom surface TSa of the island passage TS. And the guide part 89 of this embodiment is not provided with the ceiling. That is, of the first side wall 89a and the second side wall 89b, the guide portion 89 is configured such that at least a portion of the shutter 85 can pass therethrough by opening the upper end portion 89d, which is the end portion on the side of the island passage TS. be done.

The shutter mechanism 80 of the present embodiment includes a protection plate 100, which is an example of a protection section for protecting the components of the shutter mechanism 80 from foreign matter. The protection plate 100 is arranged between the bottom plate 82a and the upper end portion 89d of the guide portion 89 on the side of the island passage TS. The protective plate 100 is a rectangular plate-shaped member extending along the width direction Dw. The protective plate 100 has a planar shape perpendicular to the height direction Dh.

A plurality of second insertion holes 101 are formed in the protective plate 100 so as to pass through the protective plate 100 along the height direction Dh. The plurality of second insertion holes 101 are arranged along the width direction Dw. The plurality of second insertion holes 101 are circular holes and have diameters smaller than the diameter of any shutter pin 87 . The diameter of the plurality of second insertion holes 101 is smaller than the diameter of the game ball Bp and smaller than the diameter of the game medal Bm.

The diameter of the plurality of second insertion holes 101 is smaller than the diameter of the plurality of first insertion holes 82c. One shutter pin 87 is inserted through each of the plurality of second insertion holes 101 . Therefore, the gap between each shutter pin 87 and the edge of the second insertion hole 101 is smaller than the gap between the shutter pin 87 and the edge of the first insertion hole 82c. Therefore, even if foreign matter falls from the first insertion hole 82c, the foreign matter will fall below the protection plate 100 from the gap between the shutter pin 87 and the edge of the second insertion hole 101. is suppressed.

Here, if a foreign object that has fallen from the first insertion hole 82c enters between the guide surface 89c of the guide portion 89 and the base portion 86, it will interfere with the displacement of the base portion 86, and the shutter 85 will not move. Displacement may not be performed properly. According to the present embodiment, the protection plate 100 prevents foreign matter from entering the portion of the base portion 86 . Therefore, interference of foreign matter can be suppressed. Further, the protection plate 100 is only inserted through the second insertion hole 101 with the shutter pin 87 and is not fixed to other members. Therefore, when the shutter 85 is displaced, the contact between the shutter pin 87 and the protective plate 100 and hindrance of the displacement of the shutter 85 is suppressed. In addition, since the first shutter pins 87 at both ends are longer than the second shutter pins 87, even if the protective plate 100 swings along the height direction Dh, it can be prevented from coming off easily.

The action and effect of this embodiment will be described.
(1) According to the present embodiment, since the gas is blown from the blowing port 97, the separation of the game medium B and the abrasive K is facilitated, and the abrasive K can be easily recovered from the separation hole H.

Therefore, in the lifting device 20 capable of polishing and lifting the game media B at the same time, the outflow of the abrasive material K can be suppressed.

(6) According to the present embodiment, since the bottom surfaces (upstream side bottom members 90, 90) where the separation holes H are open vibrate, the abrasive K can be efficiently separated.
(7) According to the present embodiment, by exchanging the game ball bottom member 90A and the game medal bottom member 90B, the game balls Bp and the game medals Bm can be exchanged from each game medium B. Abrasive material K can be separated. Therefore, the lifting device 20 can be used for a plurality of types of game media B as well.

(10) According to this embodiment, the second insertion hole 101 formed in the protective plate 100 is smaller than the first insertion hole 82c formed in the bottom plate 82a. That is, since the first insertion hole 82c is relatively large, interference between the first insertion hole 82c and the shutter 85 (flow control member) is suppressed. Even if a foreign object falls from the first insertion hole 82 c , the protection plate 100 prevents the foreign object from further falling into the guide portion 89 . In particular, since the second insertion hole 101 is relatively small, the gap between the second insertion hole 101 and the shutter 85 (shutter pin 87) can also be reduced. Therefore, falling of foreign matter can be further suppressed. Therefore, interference of foreign matter can be suppressed.

(11) According to the present embodiment, since the game media B cannot pass through the first insertion hole 82c, the dropping of the game media B can be effectively suppressed.
(12) According to this embodiment, the shutter 85 is composed of a plurality of shutter pins 87 . Therefore, the shutter pin 87 forming the tip of the shutter 85 is displaced so as to push through the game media B, so that the island passage TS can be easily closed and opened.

(13) According to the present embodiment, the protection plate 100 is plate-shaped and is not fixed. Therefore, it is possible to suppress the interference of foreign matter and prevent the shutter 85 from being displaced. can.

(14) According to this embodiment, the shutter 85 is composed of a plurality of shutter pins 87 arranged along the width direction of the island passage TS. Therefore, the shutter 85 can be projected into the island passage TS to close the island passage TS while easily pushing through the game media B in the island passage TS. Therefore, the load when closing the passage can be reduced.

(15) According to this embodiment, since the tip portion of the shutter pin 87 is thinner than the base end portion, when the shutter 85 enters the island passage TS, the game medium B in the passage can be more easily removed. can be scraped apart.

(16) According to this embodiment, the distance between the plurality of shutter pins 87 is narrower than both the diameter of the game ball Bp and the diameter of the game medal Bm. Therefore, the distribution of game media B can be regulated more reliably.

Therefore, depending on the shape of the game medium B, it is possible to prevent the game medium B from being caught in the upstream end of the screw member 33 . Therefore, the lifting device 20 can be used for a plurality of types of game media B as well. The entanglement depending on the shape of the game medium B occurs, for example, when the game medals Bm are disc-shaped and are arranged so as to expand in the moving direction of the tip portion 35b of the screw 35. (see Figure 2).

(19) According to the present embodiment, since the upstream end of the screw member 33 (tip 35b of the screw 35) is a free end, the game medium B is easily caught depending on the shape of the game medium B. Become. However, since the intake port 31a for the game media B is formed at a position spaced downstream from the upstream end of the screw member 33, the entanglement of the game media B can be suppressed.

(20) According to the present embodiment, the distance between the outer peripheral surface of the screw member 33 (screw 35) and the inner surface of the lifting passage 32a is narrower than the diameter of the game ball Bp and the thickness of the game medal Bm. Neither the game balls Bp nor the game medals Bm enter the gap. Therefore, the lifting device 20 can be used for both the game balls Bp and the game medals Bm.

(21) According to the present embodiment, of the screw member 33, the pitch of the screw 35 (the spirally extending portion) is longer than the diameter of the game ball Bp and the diameter of the game medal Bm. The game medium B can be transported. Therefore, the lifting device 20 can be used for both the game balls Bp and the game medals Bm.
