Abstract

PURPOSE: To supply balls to a counting means without clogging a prize ball passage by arranging a straightening means for controlling the flow of prize balls in a parallel flow passage so that all the prize balls supplied from each parallel flow passage to a combined passage are combined within the combined passage with a time difference. CONSTITUTION: When prize balls 2 are supplied to a prize ball tank 3, the prize balls 2 are divided to parallel flow passages 41A, 41B form the bottom part of the prize ball tank 3 and supplied, and carried down therein. When the prize balls 2A, 2B are collided with the tips 8x, 8y of gears 8A, 8B, the gears 8A, 8B are rotated, and the prize balls 2A, 2B are straightened one by one and carried to the lower stream by the tooth space S of each gear 8A, 8B. Since one combined passage 42 is substantially vertically provided under the lower end of the parallel flow passages 41A, 41B, the straightened prize balls 2A, 2B are fallen into the combined passage 42. Further, since the tips 8x, 8y of the two gears 8A, 8B are relatively shifted by 30 deg. to the rotating direction, the prize ball 2B is never fallen from the parallel flow passage 41B on the gear 8B side to the combined passage 42 simultaneously with the prize ball 2A.
