Abstract

Coin detecting apparatus for distinguishing authentic coins from plates, counterfeit coins and the like, characterized in that it comprises an oscillator circuit, having a resonant tank circuit, including inductance and capacitance means to vary the amplitude of a signal produced by the oscillator circuit., according to the losses of the tank circuit, coin directing means for guiding coins, plates, counterfeit coins and the like to a predetermined location, the inductance means for the resonant tank circuit being arranged in the Korean proximity of an area of the coin-directing means in a way, by which said losses are determined by the metal content of a coin and the like which, pass through the coin-directing means; address switching means in said coin directing means, for selectively accepting and rejecting coins and the like according to the amplitude of a control signal; control means, coupled between the resonant tank circuit of the oscillator circuit and the direction switch means to convert the signal, produced by the oscillator circuit, into a control signal for the direction switch means, in a manner whereby signals produced by the oscillator circuit, having an amplitude within a predetermined range, control the direction switch means to accept a coin, and signals, produced by the oscillator circuit, having an amplitude outside of that range, control the means directional switch for rejecting a counterfeit coin and the like and guide means, extending from the coin directing means at the predetermined location for directing accepted coins from the directional switching means to a position, and for directing counterfeit coin plates and similar rejected from the direction of switching means, to another position.
