Abstract
A sheet processing apparatus includes a controller configured to control operations of the pair of aligning members such that a sheet bundle disposed on a first stacking portion is aligned by the pair of aligning members of the pair of aligning members at a position shifted to a side of one aligning member in a width direction perpendicular to the discharge direction of a sheet with respect to a sheet discharge range in which a sheet is discharged at the time of discharging the sheet from a discharge portion, and, before the aligned sheet bundle is discharged to a second stacking portion by a bundle discharge portion, the other aligning member of the pair of aligning members is moved to the outside of the sheet discharge range in the width direction.
Claims18
A sheet processing apparatus comprising:
- a discharge portion configured to discharge a sheet;
- a first stacking portion on which the sheet discharged by the discharge portion is stacked, wherein the sheet is discharged from the discharge portion onto the first stacking portion within a sheet discharge range;
- a pair of aligning members configured to move in a width direction, perpendicular to a discharge direction of the sheet, and to align the sheet on the first stacking portion in the width direction;
- a bundle discharge portion configured to discharge a sheet bundle having a plurality of sheets on the first stacking portion by pushing an end of the sheet bundle in the discharge direction;
- a second stacking portion on which the sheet bundle discharged by the bundle discharge portion is stacked;
- and
- a controller configured to control operation of the pair of aligning members such that (a) the sheet bundle disposed on the first stacking portion is aligned by the pair of aligning members at a position shifted to a side of one aligning member of the pair of aligning members in the width direction with respect to the sheet discharge range, (b) after the pair of aligning members aligns the sheet bundle, the other aligning member of the pair of aligning members moves out from the sheet discharge range in the width direction, and (c) with the other aligning member of the pair of aligning members being positioned at the outside of the sheet discharge range in the width direction, the aligned sheet bundle is discharged by the bundle discharge portion to the second stacking portion, while the sheet bundle is regulated by the one aligning member of the pair of aligning members, without contacting the other aligning member that has moved outside of the sheet discharge range.
An image forming apparatus comprising:
- an image forming portion configured to form an image on a sheet;
- a discharge portion configured to discharge a sheet on which the image is formed by the image forming portion;
- a first stacking portion on which the sheet discharged by the discharge portion is stacked, wherein the sheet is discharged from the discharge portion onto the first stacking portion within a sheet discharge range;
- a pair of aligning members configured to move in a width direction perpendicular to a discharge direction of the sheet and align the sheet on the first stacking portion in the width direction;
- a bundle discharge portion configured to discharge a sheet bundle having a plurality of sheets on the first stacking portion by pushing an end of the sheet bundle in the discharge direction;
- a second stacking portion on which the sheet bundle discharged by the bundle discharge portion is stacked;
- and
- a controller configured to control operation of the pair of aligning members such that (a) the sheet bundle disposed on the first stacking portion is aligned by the pair of aligning members at a position shifted to a side of one aligning member of the pair of aligning members in the width direction with respect to the sheet discharge range, (b) after the pair of aligning members aligns the sheet bundle, the other aligning member of the pair of aligning members moves out from the sheet discharge range in the width direction, and (c) with the other aligning member of the pair of aligning members being positioned at the outside of the sheet discharge range in the width direction, the aligned sheet bundle is discharged by the bundle discharge portion to the second stacking portion, while the sheet bundle is regulated by the one aligning member of the pair of aligning members, without contacting the other aligning member that has moved outside of the sheet discharge range.
