The cut staple storage unit is attachable to and detachable from the stapler.

A sheet processing apparatus includes a conveying portion; a conveying path for sheets conveyed by the conveying portion; a stack portion where sheets discharged from the conveying path are stacked; a first binding portion moving in a crossing direction crossing the conveying direction; a first regulating portion regulating a position of a sheet bundle stacked on the stack portion; a first guide member guiding the first regulating portion; a second regulating portion regulating a position of a sheet bundle on the stack portion in the crossing direction; a second guide member guiding the second regulating portion; a third regulating portion regulating a position of a sheet bundle on the stack portion in the conveying direction; and a second binding portion binding a corner portion of a sheet bundle without a staple. The first binding portion binds a corner portion of a sheet bundle by a staple.

A stapler includes a staple cartridge in which a staple is stored, a storage unit to which the staple cartridge is detachably attached, a staple ejecting unit which ejects the staple to penetrate a paper sheet, a cutting unit which cuts a staple leg of the staple penetrating the paper sheet, a binding unit which bends the staple leg of the staple penetrating the paper sheet to bind the paper sheet, a cut staple storage unit which stores a cut staple that is cut by the cutting unit, a cut staple quantity detection unit which detects a quantity of the cut staple stored in the cut staple storage unit, and a discharge unit through which the cutting unit and the cut staple storage unit communicate with each other to guide the cut staple to the cut staple storage unit. The cut staple storage unit is attachable to and detachable from the stapler.

Provided is a stapler device installed to staple a bundle of papers processed and discharged from an image forming apparatus or a post-processing apparatus. The stapler device includes a stapler, and a moving unit installed to allow the stapler to reciprocate in a direction intersecting with a discharge direction of the bundle of papers. The moving unit may rotate the stapler outwardly such that a bundle of papers inserted from the outside in addition to the discharged bundle of papers is stapled in at least one end position of a range of the reciprocating movement.

A sheet processing apparatus includes a conveying portion, a stack portion on which sheets are stacked, a first binding portion moving in a crossing direction crossing a conveying direction, a first regulating portion regulating a position of a sheet bundle stacked on the stack portion in the crossing direction, a first rack moving in the crossing direction with the first regulating portion, a first pinion forming a rack-pinion mechanism with the first rack, a second regulating portion regulating a position of a sheet bundle stacked on the stack portion in the crossing direction, a second rack moving in the crossing direction with the second regulating portion, a second pinion forming another rack-pinion mechanism with the second rack, a third regulating portion regulating a position of a sheet bundle stacked on the stack portion, and a second binding portion which binds a corner portion of a sheet bundle without a staple.
