Further, since the rotating member 61 is rotated around the horizontal axis 62 by the raising of the lifting frame 48, the stopping member 57 is retracted from the specific dropping port 29a at the same time when the opening / closing plate 28 is closed. For this reason, the game ball B, which has been stopped by the stopping member 57, falls downward. Since the detection switch 17 operates at the same time when the game ball B falls, the special prize device 16 is activated if another condition such as the game ball B is already in one of the starting ports 11 and 12 is satisfied. I do.

On the other hand, simultaneously with the retraction of the stopping member 57, the blocking member 58 projects near the upper part of the specific dropping port 29a, so that even if the game ball B enters the opening 27 side just before the opening and closing plate 28 closes. The game ball B is blocked by the blocking member 58 and does not enter the specific drop port 29a, but falls into one of the ball drop ports 29 on both sides thereof and falls downward. Therefore, the number of game balls B detected by the detection switch 17 after entering the specific falling port 29a is always at most one, and the detection switch 17 does not detect two or more game balls B.

In the embodiment, the specific winning device 15 of the pachinko machine has been described. However, the present invention is not limited to the pachinko machine or the specific winning device 15, and the same applies to an arrangement ball machine and the like. Needless to say, it can be implemented. Further, the number of the game balls B to be stopped in the specific dropping port 29a by the stopping member 57 may be two or more. In that case, the position of the stationary member 57 may be lowered according to the number of the game balls B.

Further, in the embodiment, the stopping member 57 and the blocking member
The stop member 57 and the blocking member 58 are moved back and forth with respect to the specific drop port 29a by providing the turning member 61 with the turning member 61 and turning the turning member 61 around the horizontal axis 62. The stopping member 57 and the blocking member 58 may be provided so as to be able to linearly move back and forth in the front-rear direction, and may be made to move in the opposite direction via a link or the like. The detection switch 17 may be provided below the stationary member 57 so that the detecting switch 17 detects a game ball B that falls when the stationary member 57 retreats.
