Abstract

PURPOSE:To make the continuous copying of originals of large sizes and ordinary sizes possible and improve copying efficiency by setting the peripheral length of a photoreceptor at integer times of the peripheral length of a sheet original gripping and winding body. CONSTITUTION:A sheet original coveying means A and a sheet original gripping, winding and conveying means B are provided, and a gate 3 which changes over original conveyance routes is provided in succession to an original insertion table 1 and feed rollers 2. A slit lighting unit 6 is provided to the means A and a slit lighting unit 11 to the means B. The original conveyance paths join after delivery rollers 7 and 12. The light of the units 6 and 11 lighting the original and reflected therefrom is conducted to a mirror 27 by mirrors 26, 29, and is imaged and exposed onto a photosensitive drum 25 by an imaging lens 28. The peripheral length of this drum 25 is set at twice the peripheral length of a sheet original gripping drum 10. If at the copying an original O is set to the table 1 and copying mode is selected, the gate 3 displaces in correspondence thereto, and the changing over of both conveyance routes is accomplished.
