(54) A coin handling apparatus


(57) This invention relates to coin selector mechanisms having in a consecutive arrangement three protection zones, two of them being optical and one of them being and electro­magnetic zone intermediate the two optical zones, the optical zones taking the form of phototransistor type sensors while the electromagnetic zone, which is preferably the central zone, is embodied by at least one and preferably two wind­ings which are interconnected and positioned opposite one another on either side of the coin path so that the fields produced by the coils intercept the coin path, the coils being connected to an oscilattor having two outputs, one output being connected to a microprocessor and the other output being connected to a rectifier connected to an analog-to-digital converter which outputs to the micro­processor.
