Title:
シート押圧装置及びこれを備える画像形成システム
Document Type and Number:
Japanese Patent JP7271172
Kind Code:
B2
Abstract:
To suppress the change in a folding height depending on whether or not a roller for additional-folding directly contacts a fold of a sheet in the additional-folding.SOLUTION: A sheet pressing device includes: a carry-in port 119 which receives a sheet previously formed into the Z-shape with two folds; an additional-folding roller 114 which is arranged on the downstream side of the carry-in port to press the fold; a lower side folding guide 111 which has a pedestal part that is arranged so as to face the additional-folding roller; a first movement mechanism which moves the additional-folding roller between the pressing position for pressing the fold by bringing the additional-folding roller close to the pedestal part and the retreat position where the additional-folding roller is moved from the pressing position with respect to the pedestal part in a direction apart from the sheet; a second movement mechanism which moves the additional-folding roller along the fold; and a control unit. The control unit controls the second movement mechanism so as to increase the frequency of moving the additional-folding roller along the fold when a sheet portion is located between the additional-folding roller and the fold.SELECTED DRAWING: Figure 2
