Abstract
A copying system which has a copying machine for forming an image on a sheet, a circular transporting device for receiving a sheet which has obtained an image on one side from the copying machine and refeeding the sheet to the copying machine for image formation on the other side of the sheet, and an automatic document feeder with a document reversing mechanism. The automatic document feeder sets a document at a specified position on a document table and discharges the document from the document table. Further, in handling a double-side document which has images on both sides, the automatic document feeder turns over the document after scanning of an image of one side. When a number of copies over the capacity of the circular transporting device are to be made in a double-side document/duplex copy mode, the document is turned over every time a number of copies corresponding to the capacity of the circular transporting device has been made.
