BOTH-SIDE TRAY OF BOTH-SIDE COPYING MACHINE, ETC

PURPOSE:To simplify a device and to improve reliability by controlling a single cam with a single solenoid through a spring clutch for various operations required for the paper discharging, array stacking, and paper refeeding of a both- side tray, and controlling respective elements through a link mechanism by said cam. CONSTITUTION:When a both-side copying mode is selected, the 2nd gate 15 is placed on the side of a both-side tray part 14, and a form turned over after a one-side copy is fixed passes through a belt conveyance part 12 and takes a U-turn through a turn roller 16 and the 2nd gate 15 to be stacked on a tray 18 by a discharge roll 17. Operation control over the discharging, array stacking and refeeding of the form to the both-side tray is exercised by a set cam 31, which consists of cams having radii r1 and r2 and are coupled with a driving shaft 32 and a spring clutch 33 to be controlled by a solenoid 34 through a couple of release levers 35 and 36.
