Sheet processing apparatus, image forming system, and sheet processing method

Abstract

The invention provides a sheet processing apparatus, image forming system, and sheet processing method. The sheet processing apparatus includes: a sheet stacking unit on which sheets are accommodated and stacked as a sheet bundle; an aligning member that is movable along a trailing end, in a conveying direction, of the sheet bundle stacked on the sheet stacking unit and that aligns the trailing end of the sheet bundle in the sheet conveying direction by abutting thereon; a binding unit that moves along the trailing end of the sheet bundle in the sheet conveying direction and binds the aligned sheet bundle; and a moving unit that moves the aligning member in the sheet conveying direction. A distance from the trailing end of the sheet bundle in the sheet conveying direction to a binding position is adjusted by moving the aligning member in the sheet conveying direction.

Problems solved by technology

Therefore, there is a problem that the stapling position cannot be adjusted to the position that each user intends to set in the paper conveying direction during edge stapling.

[0008] However, in the invention disclosed in Japanese Patent Application Laid-Open No. 2008-156073, the trailing end fence can convey the sheet pieces to the ejection claws, but cannot adjust the binding depth

In addition, in the invention disclosed in Japanese Patent Application Laid-Open No. 2009-263127, the reference fence to which the trailing end of the paper comes close when the paper is aligned in the paper conveying direction is fixed, and thus is fixed in the paper conveying direction during edge binding. The upper binding position (binding depth) cannot be adjusted to the position each user intends to set
