Abstract
PURPOSE: To enable the originals which have jammed on the way of conveying path to be withdrawn without being damaged by providing a third original detector and inhibiting resetting of a holding circuit and making possible reverse operation alone while this is actuating.
CONSTITUTION: The original having been inserted through an original feed inlet 1 causes a detector 11 to actuate, which in turn energizes a jan detecting timer 31. Within the time detrmined by a timer time variable circuit 30 which controls the timer 31 according to the original feed speed, the original causes a detector 32 to actuate to set a jam holding circuit 34, by the output whereof an original feed driving circuit 35 is stopped and breakage of the original owing to the jam is thereby prevented. If there is the original in the portion of a detector 22 at the time of jam holding, the operation of a reset circuit 33 which is driven by a jam reset switch 24 is inhibited by the signal of the detecfor 22 and the original feed driving circuit 35 is operated by the jam reset, whereby progression of the original breakage is prevented.
