Abstract

PURPOSE: To provide a paper jam detector which generates a paper jam signal when coming paper is detected at an input to sequentially transfer a signal at an output and coincidence of the transfer signal with paper output detection signal cannot be detected within timer set time.
CONSTITUTION: Microswitches 1, 2 are provided at the paper input and output of a copying machine as paper detecting means. Pulses generated at predetermined period of a shift pulse generator 3b are transferred to a shift register 3b after detecting the paper at the iuput. This pulse feeding speed is substantially equal to that of the peper. If the output of the register 3b is not coincident to the signal from the output detecting means 2 even after predetermined time determined by a timer circuit 5 is elapsed, a flip-flop 7 generates a signal representing that paper is jammed during conveyance through the passage.
