ABSTRACT:
A sheet-postprocessing apparatus includes a sheet discharger which discharges sheets to a stacker, the stacker including a first tray adjacent to the discharger for supporting trailing portions of the sheets discharged by the discharger and a second tray for supporting leading portions of the sheets, the second tray being movable in a vertical direction and disposed downstream of the first tray with respect to a sheet discharge direction, the trays being inclined so that sheets stacked thereon slide by their own weight, such that a stack of sheets supported on both trays are stapled by a stapler, the stapled set of sheets then being pushed out of the first tray to be stacked entirely by the second tray. The sheet post-processing apparatus operates in two modes, a stapling mode and a non-stapling mode wherein sheets discharged by the discharger bypass the first tray and are supported entirely by the second downstream tray.
