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 JP7308029
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 pressing pedestal 141 which is arranged so as to face the additional-folding roller; a first movement mechanism which moves between the pressing position for pressing the fold by bringing the additional-folding roller close to the pressing pedestal and the retreat position where the additional-folding roller is moved from the pressing position with respect to the pressing pedestal 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 first movement mechanism so as to increase the pressing force applied to the fold more than a case where the additional-folding roller directly faces the fold when a sheet portion is located between the additional-folding roller and the fold.SELECTED DRAWING: Figure 2
