Abstract

The coin sorting device, e.g. for checking the validity of coins (2) inserted in a coin-operated device, is responsive to the thickness (ep) and diameter (D) of the coins (2). It employs a capacitor (3) with the coins forwarded between the two capacitor plates and the capacitance variations being monitored. The capacitor (3) may form part of an oscillator circuit, so that the capacitance variations cause the oscillation frequency to vary correspondingly, with a counter recording the frequency variations. Pref. the two capacitor plates are applied to opposing sides of a coin shute (1) of insulating material, the variation in capacitance in response to passage of a coin (2) being related to the square of the coin diameter (D) and its thickness (ep).
