Abstract (en)

A coin validator comprises a microprocessor (4) which is periodically switched from a low current consumption state to an active, high current consumption state to check the output of an arrival sensing circuit (6) to determine whether a coin has arrived. The circuit (6) includes a printed circuit inductance (10) and produces an output signal the frequency of which alters when a coin arrives and is used to indicate coin diameter.
