ABSTRACT:
A both surface recording apparatus for a copying machine includes an image forming section for forming and recording an image on one surface of each sheet, which includes, on a paper transport passage to the image forming section, a turn-over guide portion for turning over and feeding-in each sheet after having been recorded on its one surface. A passage change-over section formed into a unit is attachable to and detachable from the apparatus, and is arranged to guide the sheet formed and recorded with the image at the image forming portion, through change-over either into a passage for discharging the sheet out of the apparatus or into a passage for returning the sheet to the turn-over guide portion. A sheet return section includes a switch-back passage for returning the sheet by exchanging a leading edge for a trailing edge of the sheet at one portion of a passage towards the turn-over guide portion so as to effect both surface image forming and recording of each sheet, without the need for an intermediate one-surface copied stacking tray.
