As a result, the abutting portion 94-4a of the restraining lever 94-4 projects above the discharge operating body 55, restrains the upward movement of the discharge operating body 55, and prevents the prize ball discharging operation. . Even if the discharge prevention device 94 operates as described above, the straight ball pools 52a to 52c of the first and second prize ball cases 49 and 50 have the same shape.
The spherical flow paths 48a to 48b extending from the lower end of the detection lever 94-2 to the upper valves 53 of the first and second premium ball cases 49, 50.
Since the balls arranged in the line 48c are filled and filled, the straight sphere reservoirs 52a to 52c are always filled with a fixed number of balls, thereby immediately after the operation of the discharge prevention device 94 is released. Thus, a certain number of prize balls are surely discharged.

In FIG. 2, reference numeral 95 denotes a ball stopping device which operates when the number of prize balls in the prize ball tank 46 decreases, and prevents discharge of a winning ball. As shown in FIGS. 23 to 25, the ball stopping device 95 includes a detection plate 95-2 rotatably supported by a shaft 95-1 at the bottom of the inclined guiding gutter 47a, and a shaft 95 below the mechanism plate 24. -3, and a ball locking rod 95-5 rotatably mounted on the winning ball guide path 64a. The detection plate 95-2 has an arm 95-2a protruding downward as shown in FIG. 25, and a substantially middle portion is pivotally attached to one end of a link piece 95-7 supported by a shaft 95-6.
