  In addition, an operation protrusion 80b that protrudes in the Y2 direction is provided at the center of the lock member 80, and a locking portion 80c that opens in a substantially square shape is provided at the lower end of the lock member 80. The operation protrusion 80b is used by an operator to hold the lock member 80 with a finger so that the lock member 80 can be easily slid up and down.

  Here, as shown in FIGS. 8, 13, and 15, when the lock member 80 is guided by the guide groove 150 and the guide groove 168 and slides to the lowest position (hereinafter referred to as the lock position), the sorting member The protrusions 72 b of 70 are engaged with the engaging portions 80 c of the lock member 80, and the lock member 80 restricts the rotational movement of the sorting member 70. On the other hand, although not shown, when the lock member 80 is guided by the guide groove 150 and the guide groove 168 and slides to the uppermost position (hereinafter referred to as the unlock position), the protrusion 72b of the sorting member 70 and the lock member The locking state with the locking portion 80 c of 80 is released, and the sorting member 70 can be rotated in the main body case 130.

  In a normal state, the lock member 80 is positioned at the lock position and restricts the rotational movement of the sorting member 70. In this state, the lower end of the sorting member 70 contacts the upper end of the branch wall 163, so that the curved surface 72 a of the sorting member 70 constitutes a part of the spherical passage 62. Thereby, the game ball introduced into the main body case 130 passes through the ball passage 62 and is discharged from the first ball discharge port 63. On the other hand, when the lock member 80 is slid from the lock position to the unlock position by the operator, the distribution member 70 is centered on the shaft portion 71 due to the weight of the game ball staying upstream of the ball passage 62. The curved surface 72a of the distribution member 70 constitutes a part of the ball removal passage 64. As a result, the game balls staying upstream of the ball passage 62 are distributed to the ball removal passage 64 and discharged from the second ball discharge port 65 to the outside of the pachinko machine P.

  As shown in FIGS. 13 to 15, the spherical passage 62 defined in the main body case 130 extends in the vertical direction so as to intersect the first opening 143, and the rotating plate 90 stands up in the first opening 143. Since it is accommodated in the posture, the plate surface 90 c of the rotating plate 90 is exposed to the ball passage 62 and the ball removal passage 64. As described above, since a gap is secured between the inner peripheral surface 143a of the first opening 143 and the outer peripheral surface 90a of the rotating plate 90, when the game ball flows down the ball passage 62, the upstream side After passing through the gap exposed to the side (first gap S1), it passes through the gap exposed to the downstream side (second gap S2). If foreign matter such as lint is attached to the game ball introduced from the ball introduction port 61, the foreign matter attached to the game ball flows in the first gap S1 or the second gap S2 while flowing down the ball passage 62. After entering, the pinion 100 may be transported while adhering to the gear portion 91 of the rotating plate 90. In this case, the foreign matter is sandwiched between the gear portion 91 of the rotating plate 90 and the tooth portion 100a of the pinion 100, and the torque required for the rotation of the motor 110 is increased, which causes a malfunction of the winning ball payout device 60.

  Therefore, in the pachinko machine P according to the present embodiment, the first gap S1 exposed on the upstream side of the ball passage 62 is narrower than the second gap (other gap) S2 exposed on the downstream side of the ball passage 62. By setting it as a part, the foreign matter adhering to the game ball does not easily enter the first gap S1, and the malfunction of the prize ball payout device 60 can be eliminated. That is, since the first gap S1 is a gap that first appears when the game ball passes through the rotary plate 90, if a foreign object enters the first gap S1, it falls down and is directly below the gear portion of the rotary plate 90. The possibility of being attached to 91 and transported to the pinion 100 increases. On the other hand, since the second gap S2 is a gap that appears after the first gap S1 when the game ball passes through the rotary plate 90, even if a foreign object enters the second gap S2, the first opening portion The possibility of falling to the lower part of the inner peripheral surface 143a of 143 and adhering to the gear portion 91 of the rotating plate 90 is reduced. The pachinko machine P of the present embodiment prevents the malfunction of the winning ball payout device 60 by making the first gap S1 where foreign objects are easily carried to the pinion 100 narrow.

  In this embodiment, the first gap S1 is narrower than the second gap S2 by providing the convex 152 on the inner peripheral surface 143a of the first opening 143 in which the rotating plate 90 is accommodated. Therefore, the malfunction of the prize ball payout device 60 can be solved with a relatively simple structure.

  In the present embodiment, as described above, the first gap is formed as a narrow portion by the convex portion 152 provided on the inner peripheral surface 143a of the first opening 143, but the present invention is not limited thereto. For example, the position of the rotating plate 90 accommodated in the first opening 143 is provided by providing the shaft portion 164 and the pin 144 for pivotally supporting the rotating plate 90 slightly above the position of this embodiment. Is slightly above the housing position of the present embodiment, and the gap (first gap S1) exposed to the upstream side of the ball passage 62 is made narrower than the other gap (second gap S2). It may be a simple configuration.

  Here, for example, if the gaps secured between the inner peripheral surface 143a of the first opening 143 and the outer peripheral surface 90a of the rotating plate 90 are all wide dimensions, precise dimensional management is not required. The production cost for the prize ball payout device 60 can be kept low. However, if the gap has a wide dimension, the foreign matter attached to the game ball easily enters the gap, and the malfunction of the winning ball payout device 60 cannot be eliminated. On the other hand, the clearance secured between the inner peripheral surface 143a of the first opening 143 and the outer peripheral surface 90a of the rotating plate 90 is all made narrow and narrow, so that a prize ball payout device for foreign matter intrusion can be obtained. It is also conceivable to eliminate 60 malfunctions. However, in order to make all the gaps narrow, precise dimensional management and strict assembly accuracy are required, so that the production cost for the prize ball payout device 60 increases and the work efficiency decreases. Therefore, in the pachinko machine P of the present embodiment, the malfunction of the prize ball payout device 60 is eliminated by making only the first gap S1 narrower than the other gaps (second gap S2), and the prize ball The manufacturing cost for the dispensing device 60 can be suppressed and the work efficiency can be prevented from being lowered.

  Further, in the pachinko machine P according to the present embodiment, the portion that intersects the downstream side of the ball removal passage 64 in the inner peripheral surface 143a of the first opening 143 is cut out to form the foreign matter discharge port 148, so the first gap S1. (Narrow part) or even when a foreign object has entered the second gap S2, the foreign object can be removed by free fall through the foreign object discharge port 148. Therefore, the malfunction of the winning ball dispensing device 60 occurs. Can be further reduced.

  Furthermore, in this embodiment, a ball restricting rib 149 is provided below the foreign substance discharge port 148, and the height of the ball restricting rib 149 is set to the same height as the plate surface 90c of the rotating plate 90 exposed to the ball removal passage 64. (The surface exposed in the X2 direction of the ball restricting rib 149 and the plate surface 90c are the same plane), the game ball discharged from the ball removal passage 64 to the foreign matter discharge port 148 is removed from the ball restricting rib. 149 can flow down smoothly. In addition, since the foreign material discharge port 148 is provided by using the ball removal passage 64, the foreign material that freely falls from the foreign material discharge port 148 can be discharged from the second discharge port 149 to the outside of the pachinko machine P.

  In this embodiment, the ball regulating rib 149 is provided on the inner wall surface of the cover member 140 communicating with the foreign substance discharge port 148. However, the present invention is not limited to this, and the ball regulating rib is provided on the inner wall surface of the base member 160. It may be.

  As shown in FIG. 13, the pinion 100 of the present embodiment is disposed in the vicinity of the narrow portion (first gap S1) and on the upstream side in the rotational direction of the rotating plate 90 when viewed from the narrow portion. Therefore, even if foreign matter enters the second gap S2 and adheres to the gear portion 91 of the rotating plate 90, the foreign matter crosses the narrow portion on the near side reaching the pinion 100. As a result, the foreign matter is blocked on the side of the narrow portion and is prevented from reaching the pinion 100, so that the occurrence of malfunction of the prize ball payout device 60 can be further reduced.

  Furthermore, as shown in FIG. 14, the narrow portion (first gap S <b> 1) of the present embodiment is formed in a tapered shape by a convex portion 152 provided on the inner peripheral surface 143 a of the first opening 143. Therefore, the gap is gradually narrowed on the side of the narrow portion. For this reason, it can prevent that a foreign material is caught by the side of a narrow part, and can prevent the malfunctioning of the prize-ball dispensing device 60.

  In this embodiment, the rotating plate 90, the pinion 100, the motor 110, and the sorting member 70 are all included in the main body case 130. However, the present invention is not limited to this. The structure partially exposed from case 130 may be sufficient.
