ABSTRACT:
A coin selecting apparatus includes a coin detection coil disposed in a coin channel for outputting a coin detection signal having a waveform changing gradually as the coin passes in the channel and uniquely accordance with the kind of the coin, and window device having a plurality of different windows for corresponding coins to be detected for producing a pulse signal when the coin detection signal is in a window. A timer device monitors the time duration of the pulse signal to thereby determine the validation and kind of the coin in accordance with the output from the timer device. A counter counts pulse signals produced by the window device to thereby determine the validation and kind of the coin in accordance with the count therein.
