Abstract

The coin selector for vending machines uses the variation in impedance actuated by the passage of a coin through a winding through which an alternating current is passed. This impedance is compared with a reference impedance. The selector has a single impedance measuring winding. This winding can be connected to a number of reference impedances. The reference impedances are selected as a function of an electrical signal obtained from a first coin sorting system. The analogue signal is converted into digital form by an A-D converter which multiplies by a value 1/n. The value n is programmed by a binary profile generated by a dead memory. This memory is addressed by the outputs of a counter adding +1 each time a comparator sees an analogue voltage.
