DETECTOR FOR PAPER OR THE LIKE

摘要

PURPOSE:To decrease the number of decision means for each detector by deciding whether or not there is paper in each detector by one decision means while switching signals from detectors in order by a selecting means. CONSTITUTION:Respective output signals of the detectors 11-1n are supplied to a selecting circuit 6. The selecting circuit 6 selects one of the output signals of the detectors 11-1n and consists of switches 71-7n provided correspondingly to the detectors 11-1n. The detectors 11-1n are switched at prescribed timing and decided to decide all the detectors 11-1n by one decision circuit 11.
