Abstract

PURPOSE: To make mam treatment easy and make the restarting of copying after the jam easy by letting the jam remedy controlling at paper feed conveying defect and discharge conveying defect be done separately.
CONSTITUTION: When the feeding of an original is started, a one-shot 109 starts checking jam by a post sensor 44. When the signal S2 fials to become 1, that is, when the sensor 44 fails to detect the original before the one-shot 109 times up, a gate 100 is input with the signal 0 from 109, the signal 0 of the one-shot 109 and 0 of S2 and therefore it outputs 1, thence the gate 111 input with the belt signal M1 becomes 1 and outputs JAM, at the same instant of which it stops the motor M2 of the feed roller. Since the belt 63 does not stop unless the FF116 is set upon lapse of the timer time of a one-shot 107, the original on the way of discharging is completely discharged. In this way, the restaring of copying after the jam may be made smooth.
