A copying machine with an ADF, has an AF section for separating originals in an original tray one by one, a DF section for feeding the separated original to an exposure position on a photosensitive drum, a normal original insertion port for receiving originals during normal operation, a return original insertion port for allowing insertion of return originals which must be fed again after a jam has occurred, sensors for detecting the number of copies which have been produced, the number of return originals, and the number of sheets remaining in the machine, and microcomputers for controlling the operation of the copying machine and the ADF. An interrupt copy operation can be performed with a simple operation at any time.
