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.
Claims15
A sheet processing apparatus comprising:
- a first conveying path through which a sheet is conveyed;
- a second conveying path through which a sheet is conveyed;
- a stacking tray on which the sheets conveyed from said first and second conveying paths are stacked;
- and
- an aligning unit which has a pair of aligning members which come into contact with the side edges of the sheets and aligns side edges in a width direction which crosses a sheet conveying direction of the sheets stacked on said stacking tray by movement in the width direction from a standby position where said pair of aligning members are arranged in the outside of the sheets in the width direction to an aligning position where the sheets are aligned,
- wherein the sheet conveyed from said first conveying path is discharged on a first discharge position of said stacking tray in the width direction,
- wherein the sheet conveyed from said second conveying path is discharged on a second discharge position of said stacking tray in the width direction, which is different from said first discharge position, and
- wherein said standby position is dependent on whether a sheet is discharged on said first discharge position or said second discharge position.

An image forming apparatus comprising:
- an image forming portion which forms an image onto a sheet;
- a sheet processing portion including:
- a first conveying path through which a sheet is conveyed;
- a second conveying path through which a sheet is conveyed;
- a stacking tray on which the sheets conveyed from said first and second conveying paths are stacked;
- and
- an aligning unit which has a pair of aligning members which come into contact with the side edges of the sheets and aligns side edges in a width direction which crosses a sheet conveying direction of the sheets stacked on said stacking tray by movement in the width direction from a standby position where said pair of aligning members are arranged in the outside of the sheets in the width direction to an aligning position where the sheets are aligned,
- wherein the sheet conveyed from said first conveying path is discharged on a first discharge position of said stacking tray in the width direction,
- wherein the sheet conveyed from said second conveying path is discharged on a second discharge position of said stacking tray in the width direction, which is different from said first discharge position, and
- wherein said standby position is dependent on whether a sheet is discharged on said first discharge position or second discharge position.

A sheet processing apparatus comprising:
- a first conveying path through which a sheet supplied is conveyed from a first sheet feeding apparatus;
- a second conveying path through which a sheet supplied is conveyed from a second sheet feeding apparatus;
- a stacking tray on which the sheets conveyed from said first and second conveying paths are stacked;
- and
- an aligning unit which has a pair of aligning members which come into contact with the side edges of the sheets and aligns side edges in a width direction which crosses a sheet conveying direction of the sheets stacked on said stacking tray by movement in the width direction from a standby position where said pair of aligning members are arranged in the outside of the sheets in the width direction to an aligning position where the sheets are aligned,
- wherein the sheet conveyed from said first conveying path is discharged on a first discharge position of said stacking tray in the width direction,
- wherein the sheet conveyed from said second conveying path is discharged on a second discharge position of said stacking tray in the width direction, which is different from said first discharge position,
- wherein when said pair of aligning members align the side edges of the sheets conveyed from said first conveying path, the standby position of said pair of aligning members is a position in accordance with the first discharge position, and
- wherein when said pair of aligning members align the side edges of the sheets conveyed from said first and second conveying paths, the standby position of one of the aligning members is the position in accordance with the first discharge position, and the standby position of the other is changed in accordance with each of said first and second discharge position.
