Abstract
An automatic duplex copying machine having a function for forming images on both sides of a copy paper sheet through a process in which a one-side copied paper sheet is once stored in an intermediate tray and is again led to a copying process portion after having been reversed in its transporting direction. The automatic duplex copying machine of the above described type is provided with a one-side copied paper change-over member for leading the one-side copied paper sheet towards either an intermediate tray or an intermediate sub-tray during a double-side copying operation, and a one-side copied paper selecting member for selectively supplying a one-side copied paper sheet, during a copying operation for the reverse side thereof, to the copying process portion from the intermediate tray when no paper exists in the intermediate sub-tray or from the intermediate sub-tray when papers exist therein, with one or more intermediate sub-trays being arranged in the vicinity of the intermediate tray.
