Abstract
A sheet processing apparatus is configured to press a fold line that is formed on a sheet. The sheet processing apparatus includes: a sheet supporting unit configured to support the sheet in a pressing direction for pressing the fold line; a pressing unit configured to press the fold line that is formed on the sheet that is supported by the sheet supporting unit; and a pressing-force generating unit configured to generate a pressing force for pressing the sheet supporting unit against the pressing unit at a central part in a direction along which the fold line is formed.
Claims15
A sheet processing apparatus, comprising:
- a shaft;
- and
- a press member, the sheet processing apparatus being configured to press a fold line formed on a sheet, with the press member, wherein
- the press member includes a contact part arranged such that a pressing position in which the contact part presses the fold line, sequentially changes in an axial direction of the shaft with rotation of the shaft, and
- the contact part is configured to, with rotation of the press member about the shaft, approach the fold line from a sheet surface closer to the shaft among two sheet surfaces forming the fold line, wherein the press member is configured to be rotatable in only one direction when pressing the fold line.
A sheet processing method in a sheet processing apparatus including a shaft, a press member, and a sheet abutting plate, configured to press a fold line formed on a sheet, with the press member, wherein
- the press member includes a contact part arranged such that a pressing position in which the contact part presses the fold line against the sheet abutting plate, sequentially changes in an axial direction of the shaft with rotation of the shaft, and
- the contact part is made to, with rotation of the press member about the shaft, approach the fold line from a sheet surface closer to the shaft among two sheet surfaces forming the fold line.
A sheet processing apparatus, comprising:
- a shaft;
- and
- a press member, the sheet processing apparatus being configured to press a fold line formed on a sheet, with the press member, wherein
- the press member includes a contact part arranged such that a pressing position in which the contact part presses the fold line, sequentially changes in an axial direction of the shaft with rotation of the shaft, and
- the contact part is configured to, with rotation of the press member about the shaft, approach the fold line from a sheet surface closer to the shaft among two sheet surfaces forming the fold line, wherein the contact part presses the fold line of a stopped sheet sequentially in a direction along the fold line.
