The winning ball entrance 43 is provided with a winning ball detector 80 (a proximity switch or the like) for detecting the number of winning balls, and the number of foul balls is detected by a foul ball detector (a proximity switch or the like) 82. Further, when all the game balls 45 that are used in circulation are lined up in the launch tray 41, a final ball detector 81 such as a proximity switch is installed at the last position of the game ball position. On the side wall 47 at the lower end of the launch tray 41, an outlet 46 for discharging the game ball 45 to a launch portion 58 facing the launch rod 35 is formed, and a swing piece 48 for opening and closing the outlet 46 swings on a shaft 48a. It is pivotally supported. The swinging piece 48 is formed with a downwardly inclined portion 48b in the opposite direction from the outlet 46 side in a mountain shape in a side view shown in FIGS. 3 and 4 so that the game ball 45 can be easily discharged from the outlet 46. The limit switch 49 is arranged at a position where the detection end 49a is placed on the swinging piece 48, and the counting device (not shown) is provided with the limit switch 4a.
It counts with the ON / OFF signal of 9. On the other hand, the swinging piece 4
An L-shaped operation piece 50 that can be moved up and down around a shaft 50a is provided at a position opposed to 8, and the rod 51a of a solenoid 51 is moved up and down in synchronization with the firing rod 35. In order to make it easier to discharge the game ball 45 from the outlet 46, the top portion 70 of the operation piece 50 is also provided from the outlet 46 side as shown in FIG. An upward slope is formed in the opposite direction. Needless to say, these inclined portions may be formed on only one of them. To the right of the top portion 70 of the operation piece 50, a U-shaped receiving piece 52 for receiving the game ball 45 in the launch tray 41 is provided.
A discharge port 53 communicating with the discharge tray 53 is provided on the side wall of the launch tray 41 opposite to the outlet 46 side (FIGS. 6 and 7 (cross-sectional view taken along line BB in FIG. 6)). In addition, the end of the receiving piece 52 is a game ball 4
