Abstract
A sheet processing apparatus includes a pressing unit and a shifting unit. The pressing unit has a protrusion and presses the protrusion against a fold section of a sheet. The fold section extends in one direction. The shifting unit moves at least one of the protrusion of the pressing unit and the sheet so as to shift a pressing position, at which the fold section is pressed by the protrusion, in the one direction or in a direction opposite to the one direction.
Claims12
A sheet processing apparatus comprising:
- a pressing unit comprising a protrusion and that is configured to press the protrusion against a fold section of a sheet, the fold section extending in one direction;
- and
- a shifting unit configured to move at least one of the protrusion of the pressing unit and the sheet so as to shift a pressing position, at which the fold section is pressed by the protrusion, in the one direction or in a direction opposite to the one direction,
- wherein the pressing unit comprises a first pressing member comprising a first plate-shaped base,
- wherein the protrusion protrudes from a surface of the first plate-shaped base, and
- wherein the pressing unit is configured to apply a load to the fold section from directly above the fold section to suppress occurrence of fold wrinkles at the fold section.
