Abstract

PURPOSE:To prevent transfer jam, by stopping paper feed motion and original send-in motion upon detection of original abnormal feed when sending in the original or discharging. CONSTITUTION:Print button SW1, original set switch SW2, paper end switch SW3, paper feed switch SW4, and clear and stop key SW5 are connected to flip-flops F1-Fn through differentiators d1-d3, inverters I1, I2, delay circuits DL1, DL2, timers TLM, TIMm, and OR gates O1-O4. AS a result of this, when sending in the original by means of original conveying device, if abnormality of original feed is detected, the operation after paper feed motion of the copying machine is stopped; when discharging the orignal, if abnormality of original feed is detected, next original send-in motion is prevented, so that the intended purpose may be attained.
