Abstract

PURPOSE: To make possible always accurate copying by detecting the end parts of the original having been conveyed by the original end detecting means provided just before the original exposure position and stopping the original conveying means.
CONSTITUTION: The sensors S1, S2 for detecting original passage disposed at the front and back by providing a spacing near the turn roller 3 which is close at the inlet of a contact glass 1 consist respectively of a pair of light emitting elements and a photodetectors, and are so constituted as to supply signals to control circuits for positioning etc. by detecting the leading and trailing ends of a sheetlike original P. Here, a light source 9 for exposure, a mirror group 10, an electric charger 12, an existing image device 13, cassettes 14, 14' for containing transfer paper, a regist rollers 15, a transfer charger 16, and a cleaning device 17 are disposed, so that images are formed on a photosensitive drum 11 by known image making processes.
