Abstract

PURPOSE:To obtain a copier provided with a simple and secure automatic document feeder (ADF), by detecting jamming by the drive signal of a document feeding belt and controlling successive document feed. CONSTITUTION:An original sheet document is fed from feeding section 42 with belt 63 of ADF 40, as it is photodetected with detectors 44, 45, and stopped with claw 46. Belt 63 slips on the document for a given time and corrects the document position, and then stops. This document is taken out by lowering claw 46 for a given time due to a take-out signal interlocked with exposure scanning and by redriving belt 63, and next document feed is likewise operated. When detector 45 detects the document in lowering claw 46, it is decided that the document is not taken out and is jamming. When detector 45 does not detects the document after detection of detector 44, it is also decided that the document is jamming. As a result, jamming is detected at high precision by belt drive signals without using timers or the like.
