Further, since the rotating member 61 is rotated around the horizontal shaft 62 by the elevation of the elevating frame 48, the retaining member 57 is retracted from the specific drop opening 29a at the same time when the opening / closing plate 28 is closed. Therefore, the game ball B that has been stopped by the stopping member 57 drops downward. Then, since the detection switch 17 operates at the same time as the game ball B falls, if the other conditions such as the game ball B being already in one of the starting ports 11 and 12 are satisfied, the special winning device 16 operates. To do.

On the other hand, at the same time as the stopping member 57 retreats, the blocking member 58 projects near the upper part of the specific drop port 29a, so that even if there is a game ball B that has entered the opening 27 side just before the opening / closing plate 28 is closed. , The game ball B is blocked by the blocking member 58 and does not enter the specific drop port 29a, but enters one of the ball drop ports 29 on both sides and drops downward. Therefore, the number of game balls B entering the specific drop opening 29a and detected by the detection switch 17 is always one at a maximum, 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, but the present invention is not limited to the pachinko machine or the specific winning device 15 thereof, and the same applies to an arrange ball machine or the like. It goes without saying that it can be implemented. Further, the number of game balls B retained in the specific drop port 29a by the retaining member 57 may be two or more. In that case, the position of the stopping member 57 may be lowered downward depending on the number of game balls B.

Further, in the embodiment, the retaining member 57 and the blocking member
