Abstract

PURPOSE: To improve the reliability of detection by watching each level signal time width of pulse signals in binary level having the time width corresponding to the time of passing and non-passing of signature.
CONSTITUTION: A photoelectric detector 1 consists of a projecting apparatus 1a and a light receiving apparatus 1b which detect the passing of signature. The pulse signals supplied from the light receiving device 1b are wave-form-shaped by a wave- form shaping circuit 2 and supplied to a timer circuit 3. The pulse signals supplied to the timer circuit 3 perform paper existence inspection in a first timer circuit 3a and paper absence inspection in a second timer circuit 3c. The time in each timer circuit 3a, 3b is made different, and the time width of each level signal of pulse signals in binary level having the time width corresponding to the time of passing and non-passing of signature is watched, and the paper-clogging detection signal is obtained from an OR-circuit 3d.
