Abstract

PURPOSE: To protect a copy from injury by preveting jamming previously.
CONSTITUTION: When a copy is slanted as being conveyed toward resisting rollers 104A and 104B by a feed roller 102 and separation rollers 103A and 103B, the slant running of the copy DOC is detected by slant running detection sensors 111C and 111D, and a signal of this effect is supplied to a central processing unit CPU for issuing a jam indication. When a gripper 114 fails to grip the copy, the jam indication is issued by a grip failure sensor 119, and rollers 102, 103A, and 103B are intermitted. When the copy held by the drum 105 and exposed cannot be normally separated from the drum 105, the effect is detected by a copy discharge sensor, and the jum indication is issued by the signal from the central processing unit CPU for intermitting all operations.
