Abstract

PURPOSE: To efficiently prevent coins from forming a bridge by moving a movable wall part when coins stored in a coin storage part receive a coin pressing force to turn its force direction. CONSTITUTION: When a driving motor 14 is rotated, its rotation is reduced in speed by a gear part 15 to rotate a coin sending disk 17. The rotation of the coil sending disk 17 pays off every specific number of coins, stored in a coin storage part 6 in a random state, from an exit chute 19. The rotation of the driving motor 4, on the other hand, is transmitted to an agitation rod 18 through a gear part 15. When the agitation rod 18 rotates, the coins in the coin storage part 5 are agitated, and consequently, a coin is picked up to the coin sending disk 17 and sent out. The coin pressing force operating on a rotary disk 7 operates on the slanting surface of an engagement projection, a component of the force rotates the rotary disk 7 to turn the operation direction of the coin pressing force, and then moves the coin to eliminate a bridge phenomenon.
