The release valve 47 presses against the prize ball in the discharge port 28a in a state in which the prize balls higher than the prize balls that have rushed into the inside and hit the second ball stopper pieces 42A and 42B are prevented from falling. Then, it swings to open the discharge port 28a, and discharges the number of prize balls equal to the second number of discharge balls set by the second ball stopper pieces 42A and 42B from the discharge port 28a into the prize ball discharge passage 21. can do.

Therefore, there is an effect that the setting change of the number of discharged balls of the prize balls can be performed extremely quickly and easily only by operating the switch.

Further, in this example, the inner lifting plate 35 and the first ball stopper pieces 39A,
39B is activated and the outer lifting plate 40 and both second ball stoppers 42A, 4
Since the prize balls of the second discharge quantity are discharged only when 2B is activated, the number of discharge balls of the prize balls is accurately changed, and a malfunction at the time of changing the number of discharge balls is prevented. Can be eliminated.

(Effect of the Invention) According to the present invention, the prize ball discharging mechanism can be unitized, and the prize ball can be discharged in two stages by assembling the prize ball case to the set substrate. Since the unit can be installed on the back side of the game board, it is possible to simplify and streamline the installation work of the prize ball discharging unit by eliminating the work of individually mounting the parts and mechanisms involved in discharging the prize ball. At the same time, since the prize ball case can be removed from the set substrate, it is possible to simplify parts replacement work and repair work of the ball discharging mechanism.

Also, since the case body is transparent and the prize ball flow path can be seen through from the outside, it is possible to monitor the movement of the prize ball in the prize ball flow path or the movement of the ball release mechanism from the outside and deal with the abnormality. it can.

Further, the number of discharged prize balls can be set variously by attaching and detaching the ball stopper piece, and the number of discharged prize balls corresponding to various winning modes during the game can be set.
