Abstract
In a sheet processing apparatus that performs processing for sheets after image formation such as sorting or stapling of the sheets, sheets conveyed into a waiting tray are temporarily stopped while being kept clamped by a driving roller and a pinch roller in the waiting tray and the clamping is once released. A waiting tray unit on a left side is shifted to a right side by a predetermined amount, whereby an end of the stacked sheets is pushed and shifted by a lateral wall on the left side. Thereafter, the sheets are clamped again by the roller pair and discharged.
Claims12
A sheet post-processing apparatus comprising:
- a waiting tray that has a first waiting tray unit configured to support sheets, which are conveyed thereto, from a left side in a width direction of the sheets with respect to a conveying direction and a second waiting tray unit configured to support the sheets from a right side in the width direction of the sheets, the waiting tray temporarily holding the sheets;
- a pivoting roller that clamps the sheets on the waiting tray;
- a pinch roller that clamps the sheets on the waiting tray with the pivoting roller;
- a stacking tray that receives the sheets discharged from the waiting tray;
- and
- a controller configured to temporarily stop conveyance of the sheets while the sheets on the waiting tray is kept clamped by the pivoting roller and the pinch roller, and once releases the clamping by the pivoting roller and the pinch roller, and
- the controller causes the first waiting tray unit or the second waiting tray unit on which the sheets are stacked to move to the second waiting tray unit side or the first waiting tray unit side by a predetermined amount and controls the waiting tray to push a side of the stacked sheets with a lateral wall of the moving waiting tray unit to sort the sheets.
