ABSTRACT:
A coin detecting device is described comprising a coin chute of the gravity type defining a path down which a coin travels, a delayed-reset microswitch having an actuating arm which is tripped by the passage of the coin down the path, and a plurality of unidirectional coin passing gates located along the path for preventing a cheating operation known as stringing. Stringing involves dropping a coin with a string attached past such a detecting device and manipulating the coin with the string in a manner to make it appear that several coins have passed. The coin detecting device is effective in preventing stringing with coins having slotted and unslotted bodies.
