Abstract
PURPOSE: To certainly detect conveyance anomaly by detecting the revolution speed of a pressure roller and taking-out timing signal and comparing the cycle with standard time.
CONSTITUTION: When conveyance anomaly is formed, in other words, conveyance becomes impossible due to jammed paper, anomaly is formed in the revolution of a pressure roller. Then, the cycle of revolution of a timing disc varies, and the interval for the output of "0" level signal from a detector 8 due to the light shielding part 7a of the timing disc is elongated. Therefore, the charging voltage of a condenser 27 reaches the threshold level of a buffer circuit 30. Thus, signal of conveyance anomaly is output from the buffer circuit 30.
