Abstract
A sheet processing apparatus that forms a folding line on a sheet includes first and second folding rollers that form a folding line on the sheet by rotating a bent sheet while pinching from sheet surfaces and a first pressing unit that presses the second folding roller against the first folding roller in an arbitrary portion in a rotating shaft direction of the second folding roller.
Claims21
A sheet folding apparatus comprising:
- a first pair of folding members configured to fold a sheet;
- a first pair of conveying members configured to convey the sheet that has been folded by the first pair of folding members;
- and
- a sheet detector configured to detect the sheet at a position downstream from the first pair of conveying members in a first sheet conveyance direction, wherein
- the sheet folding apparatus is configured to convey the sheet by a distance downstream from the sheet detector in the first sheet conveyance direction after a folding line of the sheet passes through a nip of the first pair of conveying members, and stop the conveyance of the sheet.
2 more elements
An image forming apparatus, comprising
- a main body;
- an image forming unit configured to form an image on a sheet;
- and
- a sheet folding apparatus, the sheet folding apparatus being in the main body and including,
- a first pair of folding members configured to fold the sheet,
- a first pair of conveying members configured to convey the sheet that has been folded by the first pair of folding members, and
- a sheet detector configured to detect the sheet at a position downstream from the first pair of conveying members in a first sheet conveyance direction, wherein
- the sheet folding apparatus is configured to convey the sheet by a distance downstream from the sheet detector in the first sheet conveyance direction after a folding line of the sheet passes through a nip of the first pair of conveying members, and stop the conveyance of the sheet.
5 more elements
An image forming system, comprising:
- an image forming apparatus configured to form an image on a sheet;
- and
- a sheet folding apparatus, the sheet folding apparatus being separate from the image forming apparatus and including,
- a first pair of folding members configured to fold the sheet,
- a first pair of conveying members configured to convey the sheet that has been folded by the first pair of folding members, and
- a sheet detector configured to detect the sheet at a position downstream from the first pair of conveying members in a first sheet conveyance direction, wherein
- the sheet folding apparatus is configured to convey the sheet by a distance downstream from the sheet detector in the first sheet conveyance direction after a folding line of the sheet passes through a nip of the first pair of conveying members, and stop the conveyance of the sheet.
