Sheet processing apparatus and image forming system

摘要

According to an embodiment, there is provided a sheet processing apparatus includes a stacking unit that stacks a sheet conveyed thereto; a first alignment unit that aligns the sheet or a bundle of sheets stacked in the stacking unit in a sheet conveying direction; a second alignment unit that aligns the sheet or the bundle of sheets stacked in the stacking unit in a direction orthogonal to the sheet conveying direction; a pressing unit that presses the bundle of sheets at an end portion thereof on a predetermined one side; and a control unit that causes at least one of the first and second alignment units to execute an alignment operation during a press operation of the sheet or the bundle of sheets performed by the pressing unit.

主权项

1. A sheet processing apparatus comprising:
a stacker configured to stack a sheet conveyed thereto; a first alignment device configured to align the sheet or the bundle of sheets stacked in the stacker in a direction orthogonal to a sheet conveying direction; a pressing device movable in a direction perpendicular to the sheet conveying direction and configured to press the bundle of sheets at an end portion thereof on a predetermined one side; a controller configured to cause the first alignment device to execute an alignment operation during a press operation of the sheet or the bundle of sheets performed by the pressing device; a binder configured to bind the bundle of sheets that has been aligned by the first alignment device, wherein the pressing device presses an end of the bundle of sheets on a side to be bound by the binder; and, a moving device configured to move the binder in the direction orthogonal to the sheet conveying direction, wherein the pressing device moves in the same direction in synchronization with the movement of the binder by the moving device.
