Title: Coin validating arrangement
IPC: G07D5/08
Filed: 1980-12-03
Abstract: A coin validating arrangement for a coin operated machine, comprising a coin chute (5) having an upstream coil (8) for sensing a true coin and producing a Q signal output only when a true coin is properly inserted, an obturator (11) generally downstream of the true coin sensing coil, a coin acceptance coil (21) generally downstream of the obturator, and a validating circuit (41) which enables the coin acceptance coil to produce an A signal output which in turn generates an accept signal which activates the machine only when no Q signal output is being produced. In a preferred arrangement, an intermediate or zoning coil (18) produces a Z signal output as it watches the coin through the obturator from the Q coil to the A coil, and production of the accept signal is also dependent on the Z signal.
