Claims

An intermediate stacking unit capable of stacking sheets;
Conveying means for conveying a sheet to the intermediate stacking unit;
An alignment unit that moves the sheet on the intermediate stacking unit in a direction that intersects the conveying direction by the conveying unit, and aligns the sheet end in the intersecting direction;
A reference member that abuts and aligns the end of the sheet moved by the aligning means in the intersecting direction;
A sheet holding unit that is arranged to be movable up and down at one end in the moving direction of the sheet by the alignment unit, and presses the aligned sheet abutted against the reference member against the stacking surface of the intermediate stacking unit in the lowered state ;
And a control means for controlling the front Symbol alignment means and said sheet holding means, and
The control means sets the sheet alignment position by the alignment means to a position where the sheet moved by the alignment means is abutted against the sheet holding means in the lowered state, and the sheet holding means is in the raised state. The sheet processing apparatus can be changed to a position where the sheet moved by the aligning means is brought into contact with the reference member and aligned .

It said control means moves said reference member, the sheet processing apparatus according to claim 1, wherein the changing the alignment position by the alignment means.

The intermediate stacking unit includes a fixed stacking unit disposed on the upstream side in the sheet conveying direction so as to face the sheet holding unit, and both ends of the sheet in the intersecting direction connected to the downstream side of the fixed stacking unit in the sheet conveying direction. A pair of sheet supporting members that can move in a direction away from each other and release the support at both ends , and a discharge unit that moves the sheets from the fixed stacking portion toward the pair of sheet supporting members. And
The control unit moves the sheet from the fixed stacking unit toward the sheet support member pair by the discharge unit, and separates the sheet support member pair from each other to receive the aligned sheets from the intermediate stacking unit. The sheet processing apparatus according to claim 1 , wherein the sheet is discharged to a part.

The sheet processing apparatus according to claim 3 , wherein the sheet support member pair integrally includes the aligning unit.

5. The sheet processing apparatus according to claim 3 , wherein the discharging unit is a pair of rollers capable of being pressed / separated.

A post-processing unit that performs post-processing on the sheets stacked on the intermediate stacking unit;
Wherein, with respect to a sheet that does not perform post-processing, the sheet processing apparatus according to any one of claims 1 to 5, characterized in that to change the alignment position by the alignment means.

The sheet processing apparatus according to claim 6 , wherein the post-processing unit is a stapling device that staples edges of sheets stacked on the intermediate stacking unit .

Image forming means for forming an image on a sheet;
An image forming apparatus comprising: the sheet processing apparatus according to claim 1, which performs processing on a sheet on which an image is formed by the image forming unit.

Image forming means for forming an image on a sheet;
An intermediate stacking unit capable of stacking sheets on which images are formed by the image forming unit;
Conveying means for conveying a sheet to the intermediate stacking unit;
An alignment unit that moves the sheet on the intermediate stacking unit in a direction that intersects the conveying direction by the conveying unit, and aligns the sheet end in the intersecting direction;
A reference member that abuts and aligns the end of the sheet moved by the aligning means in the intersecting direction;
A sheet holding means that is arranged to be movable up and down at one end in the moving direction of the sheet by the aligning means, and presses the aligned sheet abutted against the reference member against the stacking surface of the intermediate stacking section in the lowered state ;
And a control means for controlling the front Symbol alignment means and said sheet holding means, and
The control means sets the alignment position of the sheet by the alignment means to a position where the sheet moved by the alignment means abuts against the lowered sheet holding means, and the sheet holding means is raised, An image forming apparatus capable of selecting a position where the sheet moved by the aligning unit is brought into contact with the reference member and aligned .
