Abstract

A coin sorting device is designed to inhibit tampering with a coin operated machine by means of a wire, metal tape or the like, and to further prevent non-acceptable coins from being accepted by the coin-operated machine. The various embodiments of the device include a cancel mechanism for returning non-acceptable coins from a coin sorting passage to a coin return chute, a shutter movably arranged across the inlet of a coin acceptance chute for completely closing the inlet to prevent unauthorized operation, a non-acceptable coin block arm extruding into the inlet of the coin acceptance chute to block the inlet upon detection of a coin in the return chute, a coin hole engaging wire for detecting and engaging non-acceptable coins with center holes, a mill engaging arm with an engaging thin nail to detect and engage non-aceptable milled coins, and an electromagnetically operated blocker rotatable between a withdrawn position and a block position wherein the blocker extends into the inlet of the coin sorting passage across the coin inserting opening to prevent insertion of non-acceptable coins. The device is advantageous for preventing tampering and operation with non-acceptable coins, is capable of being inexpensively mass produced, and is high in quality.
