ABSTRACT:
A sheet finishing and stacking apparatus includes a sheet transport path which stacks sheets onto a stapler tray, the stack is finished by a stapler, and a discharge roller and a pushed out member transport the stack onto a discharge tray. The discharge tray is driven in a vertical direction as stacks of sheets are deposited thereon. While the push-out member is delivering the stack to the discharge tray, an auxiliary lower discharge plate extends along a direction of the push-out member to prevent the stack from buckling. In another embodiment, the discharge tray is temporarily lowered and then raised back to an upper limit as the push-out member delivers the stack to the discharge tray.
