Abstract

PURPOSE:To easily copy one sheet of original into multiple sheets by holding a sheetlike original on a drumlike supporting body, and providing a passage which permits remounting of the original discharged from this drum again on the drum, in a copying machine having an automatic original feeder. CONSTITUTION:The original on an original placing tray 202 is mounted to an original holding drum 206 by way of a feeding roller 203 and a separating roller 204. The original on the drum is exposed in an exposure part E, separates from the drum and is discharged onto an original discharging tray 209. The 3rd passage 284 is connected to an original input passage from the midway of the discharge passage.In the case of copying plural times, the original passes through this 3rd passage 284 and circulates plural times.
