ABSTRACT:
A coin refund signal generator includes a coin sorting sensing circuit which is normally in a quiescent state but which generates a sensing signal of a first duration in response to the deposit of a genuine coin and of a second duration in response to the actuation of a coin return requesting device. A detection circuit determines the duration of the sensing signal and generates a coin refund signal if the duration of the sensing signal equals or exceeds the second duration.
