Abstract
A sheet processing apparatus has: a plurality of conveying paths which convey sheets; and front and back aligning members which perform width alignment in the direction which crosses the sheet conveying direction of the sheets conveyed from the conveying paths. Standby positions when the front and back aligning members approach side edges of the sheets from the standby positions and perform the width alignment of the sheets at the width aligning position are made different every sheet on the basis of discharge position information of the sheets to the plurality of conveying paths.
Claims20
A sheet processing apparatus comprising:
- a plurality of conveying paths selectable to convey a sheet;
- and
- an aligning unit which aligns the sheets in a width direction which crosses a sheet conveying direction of the sheets conveyed from said plurality of conveying paths,
- wherein said aligning unit has a pair of aligning members which come into contact with side edges of said sheet in the width direction from standby positions where said aligning members are arranged in the outsides of the side edges in the width direction of the sheets and align said sheets, and
- a controller that controls the operation of the aligning unit to change said standby positions in accordance with discharge position information generated in response to the selection of a conveying path, wherein the discharge position information corresponds to said plurality of conveying paths.
An image forming apparatus comprising:
- an image forming portion which forms an image onto a sheet;
- a sheet processing portion including a plurality of conveying paths selectable to convey a sheet, and an aligning unit which aligns the sheet in a width direction which crosses a sheet conveying direction of the sheets conveyed from said plurality of conveying paths, wherein said aligning unit has a pair of aligning members which come into contact with side edges of said sheet in the width direction from standby positions where said aligning members are arranged in the outsides of the side edges in the width direction of the sheets and align said sheets;
- and
- a controller that controls the operation of the aligning unit to change said standby positions in accordance with discharge position information generated in response to the selection of a conveying path, wherein the discharge position information corresponds to said plurality of conveying paths.
