Abstract
A sheet processing device includes a folding unit, a first roller, and a pair of second rollers. The folding unit folds a sheet and forms a fold in the sheet. The pair of second rollers moves in a fold direction and additionally folds the fold. The first roller includes a first large diameter section and a first small diameter section. Each of the pair of second rollers includes a second large diameter section and a second small diameter section. The second large diameter section holds the sheet between the second large diameter section and the first small diameter section. The second small diameter section holds the sheet between the second small diameter section and the first large diameter section.
Claims20
A sheet processing device, comprising:
- a folding component configured to fold a sheet and form a fold in the sheet;
- a first roller that rotates around a first axis extending in a conveying direction orthogonal to a fold direction and configured to move in the fold direction;
- and
- a pair of second rollers that rotate around second axes extending in the conveying direction, configured to move in the fold direction while holding the sheet between the pair of second rollers and the first roller and additionally fold the fold, and disposed side by side in the fold direction, wherein
- the first roller includes a first large diameter section present in a first position in the conveying direction and a first small diameter section present in a second position in the conveying direction and is smaller in diameter than the first large diameter section, and
- each of the pair of second rollers includes a second large diameter section present in the second position and holds the sheet between the second large diameter section and the first small diameter section and a second small diameter section present in the first position, holds the sheet between the second small diameter section and the first large diameter section, and is smaller in diameter than the second large diameter section.
An image forming apparatus, comprising:
- an image forming section;
- and
- a sheet processing device, comprising:
- a folding component configured to fold a sheet and form a fold in the sheet;
- a first roller that rotates around a first axis extending in a conveying direction orthogonal to a fold direction and configured to move in the fold direction;
- and
- a pair of second rollers that rotate around a second axes extending in the conveying direction, configured to move in the fold direction while holding the sheet between the pair of second rollers and the first roller and additionally fold the fold, and disposed side by side in the fold direction, wherein
- the first roller includes a first large diameter section present in a first position in the conveying direction and a first small diameter section present in a second position in the conveying direction and is smaller in diameter than the first large diameter section, and
- each of the pair of second rollers includes a second large diameter section present in the second position and holds the sheet between the second large diameter section and the first small diameter section and a second small diameter section present in the first position, holds the sheet between the second small diameter section and the first large diameter section, and is smaller in diameter than the second large diameter section.
