Abstract:
In a bill validator comprising a case having an inlet into which a bill is inserted and an outlet from which the bill is discharged; an inlet sensor for detecting insertion of the bill into the inlet; a conveyer device for transporting the bill from the inlet to the outlet through a passageway in the case; a bill sensor disposed adjacent to said passageway for converting into electric signals optical or magnetic feature of the bill moving through the passageway; and a validating control circuit electrically connected with the inlet sensor, conveyer device and bill sensor for driving the conveyer device; said conveyer device having a belt and a conveyer motor drivingly connected with said belt; the improvement comprising:a temperature sensor for producing a detection signal when a temperature in said case is lowered below a predetermined level; a first timer for starting counting a confirmative period of time upon receiving the detection signal from said temperature sensor, and a second timer for producing a drive signal when said first timer counts up said confirmative period of time to drive said conveyer motor for a predetermined warming-up period of time.
