Abstract
In accordance with an embodiment, a sheet processing apparatus comprises a processing tray configured to load sheets to which a post processing is executed; a pair of alignment plates arranged on the processing tray at a predetermined interval and configured to move in a direction orthogonal to a sheet conveyance direction and align the sheets on the processing tray in the sheet width direction; and a controller configured to control the pair of the alignment plates to move towards each other to first alignment positions at which the sheets are aligned in the direction and stop, and control the pair of the alignment plates to move towards each other to second alignment positions without moving the pair of the alignment plates in a reverse direction to align the sheets.

A sheet processing apparatus, comprising:
- a processing tray configured to load sheets to which a post processing is executed;
- a pair of alignment plates arranged on the processing tray at a predetermined interval and configured to move in a direction orthogonal to a sheet conveyance direction and align the sheets on the processing tray in the sheet width direction;
- a controller configured to control the pair of the alignment plates to move towards each other to first alignment positions at which the sheets are aligned in the direction and stop, and control the pair of the alignment plates to move towards each other to second alignment positions;
- an interval between the pair of the alignment plates at the second alignment positions is narrower than that at the first alignment positions;
- and
- a vertical alignment member configured to align the sheets on the processing tray in the conveyance direction of the sheet, wherein
- after the vertical alignment member aligns the sheets on the processing tray, the controller positions the pair of the alignment plates at the first alignment positions to align the sheets, and
- the controller is further configured to control the vertical alignment member to align the sheets on the processing tray again in the conveyance direction of the sheet after the pair of the alignment plates reaches the first alignment positions, and control the pair of the alignment plates to move to the second alignment positions without moving the pair of the alignment plates in a reverse direction to align the sheets.
A sheet processing method, comprising:
- loading sheets on a processing tray;
- aligning the sheets on the processing tray in the sheet width direction by moving a pair of alignment plates arranged on the processing tray at a predetermined interval in a direction orthogonal to a sheet conveyance direction;
- moving the pair of the alignment plates towards each other to first alignment positions at which the sheets are aligned in the direction and stopping;
- moving the pair of the alignment plates towards each other to second alignment positions;
- an interval between the pair of the alignment plates at the second alignment positions is narrower than that at the first alignment positions;
- aligning the sheets on the processing tray in the conveyance direction of the sheet;
- after aligning the sheets on the processing tray, positioning the pair of the alignment plates at the first alignment positions to align the sheets;
- aligning the sheets on the processing tray again in the conveyance direction of the sheet after the pair of the alignment plates reaches the first alignment positions;
- and
- moving the pair of the alignment plates to the second alignment positions without moving the pair of the alignment plates in a reverse direction to align the sheets.
