Sheet processing apparatus and method, as well as controlling apparatus

摘要

A sheet processing apparatus which is capable of completing a bound document containing appropriately Z-folded sheets when performing folding together with edge cutting and binding. The sheet processing apparatus controls a Z-folding process, a cutting process, and a binding process for a sheet. A first folding position from a free end of the sheet coincides with a position corresponding to half a width of the sheet excluding a cut width of the sheet a binding margin, when the Z-folding process, the cutting process, and the binding process are executed.

主权项

1. A sheet folding apparatus comprising:
a folding unit configured to perform a Z-folding process to provide first and second folds to a sheet; a first obtaining unit configured to obtain a binding margin width of the sheet in a binding process performed to the sheet to which the Z-folding process has been performed; a second obtaining unit configured to obtain a cut width of the sheet in a cutting process performed to the sheet to which the binding process has been performed; a determination unit configured to determine respective first and second folding positions of the first and second folds in the sheet provided by the Z-folding process so that a first length between a cut edge-side free end of the sheet to which the cutting process has been performed and the first fold, which is closer to the cut edge-side free end of the sheet than the second fold, is half of a second length between a bound position and the second fold, which is closer to the bound position than the first fold, based on the binding margin width obtained by the first obtaining unit and the cut width obtained by the second obtaining unit; and a control unit configured to cause the Z-fold folding process to be performed based on the first and second folding positions determined by the determination unit.
