PURPOSE:To speed up copying, by providing the second and the third sheet originals conveyance routes near the first route for ejecting the originals from an exposure station and returning them to a tray, reversing them from the third route, and causing them to join those carried on the second route. CONSTITUTION:A tray 1 for stacking original sheets is installed above an exposure station comprising a lamp, etc., the first conveyance route 6 for feeding the original sheets one by one from the tray 1 to the exposure station, and the second conveyance route 10 for ejecting them from the exposure station and returning them to the tray 1 located near the first route 6 are provided. When both sides of the original are copied, before completing copying, a route switching device 16 is changed over from the position as shown by the full lines to the position as shown by the dash lines, the original 116 with the first image copied is carried in the left direction by the friction force with a belt 18, pushing a flexible guide 110 aside, intrudes onto the third route 114, and reaches a sensor 117.
