A sheet binding processing apparatus includes a binding device which performs a binding process on a sheet bundle stacked on a stacking unit and a sheet bundle set at a manual setting portion, the stacking unit stacking introduced sheets, a sheet bundle being set to the manual setting portion from an outside; a moving portion which moves the binding device to a first binding position for performing the binding process on a sheet bundle stacked on the stacking unit and a second binding position for performing the binding process on a sheet bundle set at the manual setting portion; and a controller which causes the binding device, in a case that the binding process is not performed on a sheet bundle stacked on the stacking unit, to wait due to the moving portion at a position different from the first binding position.

A sheet processing apparatus for processing a sheet includes a conveying path in which a sheet is conveyed; a setting portion including an opening formed in a cover, a setting face supporting a lower face of a sheet bundle inserted through the opening from an outside of the sheet processing apparatus, and a regulating face which regulates a position of the sheet bundle; a stack portion on which sheets are stacked; a binding unit which is configured to bind a sheet bundle set on a sheet setting area; and a punching unit being configured to be movable in the sheet width direction, the punching unit including a punching portion which forms a punch hole. In the sheet width direction, the sheet setting area is arranged as being overlapped with a moving area of an end of the one side of the punching unit in the sheet width direction.

To enable a bunch of sheets to be reliably discharged to a stack tray, also in the case where weight of the bunch of sheets formed on a processing tray is large, upon receiving a printing command, a main body control section checks information on an ink discharge amount in printing on a sheet, the number of sheets, sheet type and printing mode (two-side/one-side). By this means, the section recognizes weight of the bunch of sheets formed on the processing tray, and when determining that the weight is heavier than predetermined weight, deceases an upper limit value of the number of sheets of a bunch of sheets formed at a time to report to a user.

A system may include a finishing device to receive a print job. The print job may move about a first axis of the finishing device. The system may further include a stapling device contained within the finishing device. The stapling device to move about a second axis of the finishing device, and the second axis may be perpendicular to the first axis. A sensor may be located on the stapling device to identify a first edge of the print job. The first edge of the print job may be a leading edge of the print job as the print job moves about the first axis.

A sheet binding apparatus includes a sheet conveyer, a tape holder, and first and second rollers. The sheet conveyer is configured to convey a sheet bundle with a leading end shifted, the sheet bundle having opposing first and second surfaces. The tape holder is configured to hold a tape at a position to which the leading end reaches such that the tape adheres to the leading end. The leading end with the tape passes and is pressed between the first and second rollers. The second roller is positioned upstream in the sheet forward direction from the first roller and to face the second surface of the sheet bundle. An angle between a line perpendicular to the sheet forward direction and a line passing rotational axes of the first and second rollers is greater than 0 and less than 90.

An image forming apparatus, including: a printing unit configured to print on a sheet; a bookbinding unit configured to perform a cutting process of cutting a binding member for binding a plurality of sheets before sheets printed by the printing unit are stacked on a stack tray and perform a binding process of binding the sheets by the cut binding member; and a controller configured to cause the bookbinding unit to perform the cutting process of the binding member based on sheet size information, the controller controls, in a case of producing a plurality of copies of bookbound products, not to perform the cutting process of the binding member of a second copy while sheets are stacking as a first copy, but to perform the cutting process of the binding member of a next copy while sheets are stacking as each of the second copy and subsequent copies.

A sheet processing apparatus includes a conveying portion for conveying sheets, a conveying path for sheets, a stack portion for stacking sheets, a first binding portion having a first binding member and moving in a crossing direction crossing to the conveying direction, a first regulating portion which regulates a position of a sheet bundle stacked on the stack portion, a second regulating portion which regulates a position of a sheet bundle stacked on the stack portion, a third regulating portion which regulates a position of a sheet bundle, and a second binding portion which has a second binding member and binds 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. The second binding member is located at a downstream of the first binding member in the conveying direction.
