Abstract
A sheet post-processing device is provided with a pushing device for pushing a predetermined position of a sheet stack in a direction substantially perpendicular to a direction that the sheet stack is conveyed, and a pair of rotating bodies for performing a folding operation. In the folding operation, a position of the sheet stack pushed by the pushing device is moved away from a contact point between rotational centers of the rotating bodies.
Claims9
A sheet post-processing apparatus for post-processing a sheet, comprising:
- pushing means for pushing a predetermined position of a sheet stack including the sheet in a direction substantially perpendicular to a direction that the sheet stack is conveyed;
- and
- a pair of rotating bodies disposed adjacent to the pushing means for folding the sheet stack pushed by the pushing means at a folding position, said rotating bodies having means for moving the folding position from a contact point between rotational shafts of the pair of the rotating bodies when folding.
A sheet post-processing apparatus for post-processing a sheet, comprising:
- pushing means for pushing a predetermined position of a sheet stack including the sheet in a direction substantially perpendicular to a direction that the sheet stack is conveyed;
- and
- a pair of rotating bodies disposed adjacent to the pushing means for folding the sheet stack pushed by the pushing means, at least one of said pair of the rotating bodies having at least two curved portions with different curvatures.
