Abstract
A sheet post-treating apparatus includes a gripper that moves a pile of sheets from a sorting tray to a discharge tray. The position of the pile of sheets on the tray is selected between alternative discharge positions so that successive piles can be jogged. A stapler is provided along the path to a discharge position to engage the edge of the pile if stapling is desired.
Claims31
A sheet post-treating apparatus, comprising:
- a plurality of sorting trays to which sheets supplied from an image forming apparatus are collected and stacked in order;
- tray moving means for sequentially moving the sorting trays to a predetermined take-out position;
- take-out means including means for gripping an edge of a pile of the sheets stacked on the sorting tray in the take-out position and for collectively discharging the pile;
- a discharge tray to which the pile of the sheets are discharged by the take out means to a discharge position and
- control means for controlling the discharge position by controlling the movement of the take-out means in such a manner that the discharge position to the discharge means is alternately changed between a first discharge position and a second discharge position.

A sheet post-treating apparatus, comprising:
- at least one sorting tray to which sheets supplied from an image forming apparatus are collected and stacked in order;
- take-out means including means for gripping an edge of a pile of the sheets stacked on the sorting tray in the take-out position and for collectively discharging the pile, wherein said take-out means takes out the pile of the sheets in a discharge direction which is defined to be perpendicular to a direction in which the sheet is supplied from the image forming apparatus to the sorting tray;
- a discharge tray to which the pile of the sheets are discharged by the take-out means to a discharge position;
- and
- control means for controlling the discharge position by controlling the movement of the take-out means in such a manner that the discharge position to the discharge means is alternately changed between a first discharge position and a second discharge position.

- and
- control means for controlling the discharge position by controlling the movement of the take-out means in such a manner that the discharge position to the discharge means is alternately changed between a first discharge position and a second discharge position wherein said control means controls the movement of the take-out means in such a manner that the pile of the sheets stacked on odd-numbered sorting trays, are taken out to the discharge means in one of first and second discharge positions and the pile of the sheets stacked on even numbered sorting trays are taken out to the discharge means in the other of the first and second discharge positions.
