Abstract
Abstract A coin dispenser for discharging coins stored in a bucket in an automatic vending machine, a money exchanging machine, a coin-operated amusement machine such as a slot machine and the like, comprising a bucket for storing a number of coins therein which has an opening at its bottom, a rotary disk driven by a motor for receiving thereon coins supplied from the bucket through the opening, the rotary disk being adapted to rotate in a substantially horizontal plane and causing the coins placed thereon to slide outwardly with centrifugal force; and a guide wall adapted to guide the coins impelled by centrifugal force along the periphery of the rotary disk and formed with an opening for discharging the coins. The rotary disk comprises a rotary pedestal including a hub fixed to an output shaft of a motor and a plurality of frames projecting in the radial direction from the hub, and a thin disk fixed to the rotary pedestal and adapted to bear the coins thereon. In this way, the rotary disk as a whole can be made light in weight, and can greatly reduce the load on the motor when the rotary disk is suddenly stopped upon having finished paying out coins.
