Abstract

PURPOSE: To accurately detect paper jam with a simple structure by monitoring the period of the output pulse signals of a photoelectric detector with each time width corresponding to the passing or nonpassing time of a signature.
CONSTITUTION: The pulse signals P of two-value levels H and L with each time width corresponding to the passing or nonpassing time of a signature, that are transmitted from a photoelectric detector 1 in accordance with the passing of the signature are converted into differential pulses DP by a signal conversion circuit 2 and entered to a signal period monitoring circuit 3. When the period of the differential pulses DP exceeds a preset period, the signal period monitoring circuit 3 transmits H-level paper jam detection signals.
