Abstract

PURPOSE:To improve the operation characteristics and increase the copying speed, by temporarily prohibiting the feed of next original with the output of a photo detecting means to detect the light from a scanning means after scanning of the original. CONSTITUTION:Plural originals stored in a bucket part 41 of an original automatic feed device 40 are separated one by one from the bottom sheet, and sent to the exposure position by a belt 63 to be scanned with light by an optical system which makes reciprocal motions, so as to be exposed on a drum 11 and copied on a transfer paper. The position of the original is optically detected by detectors 44, 45, 47, 48 so as to be controlled with respect to the optical system driving motion. When the final exposure by the original in the exposure position is finished, the afterglow after the optical system of exposure lamp is inverted and extinguished is detected by the detector 45, and driving of rollers 61, 62 in the feeder section is prohibited while the afterglow is being detected, and a sufficient interval is taken between the original finished exposure and a next original to be fed.
