Abstract: A folding processing unit in a sheet post-processing device comprises a first conveying path, upstream side conveying rollers, downstream side conveying rollers, folding rollers between the upstream side conveying rollers and the downstream side conveying rollers, and the second folding rollers. The folding rollers fold a sheet at the first nip portion between the two rollers. The second folding rollers are placed at a downstream side of the first nip portion. An edge face detection sensor for detecting the edge face of the sheet is placed on the first conveying path, at a downstream side of the first nip portion. The second folding rollers pinch the sheet folded by the first nip portion at the second nip portion, to further fold the sheet, based on the detection result of the edge face detection sensor. Herewith, degree of accuracy for folding behavior improves.

Abstract: Sheet pressing means (59) is provided that assists the formation of a bend in a sheet (S) and that freely swings to guide the bend into the nip portion of a second folding roller pair (a second roller (54) and a third roller (55)). The pivot point (594) of the sheet pressing mean (59) is arranged on the side of the nip portion of a first folding roller pair with respect to a common tangent (L1) of the first folding roller pair (a first roller (53) and the second roller (54)) on the downstream side in a sheet transport direction, and is arranged to be lower than a line (L3) that is parallel to a common tangent (L2) of the second folding roller pair on the upstream side in the sheet transport direction and that passes through the center (O) of the first roller (53). Thus, it is possible to reliably perform processing for folding the sheet in a predetermined position regardless of the material quality, the thickness and the like of the sheet.

Abstract: An accordion folding mechanism folds a sheet fed from an image forming apparatus in an accordion shape by repeating a mountain fold and a valley fold in a direction perpendicular to a sheet conveying direction. A size setting unit sets a folding size of the mountain fold and the valley fold. A size adjusting unit compares a size of the sheet fed from the image forming apparatus with the folding size, and adjusts the folding size of a predetermined number of folds at a trailing end of the sheet.

Abstract: A stack of sheets of sheet material is stapled along an axis and fed to a position from which it is folded along the axis by a blade to form a booklet having a curved spine. The blade also inserts the booklet into a position between clamping jaws and determines its final position therebetween. Rotatable guide rollers guide the sheets into the gap and are fitted with one-way clutches to resist upward movement of the folded sheets upon retraction of the blade from the gap. In a first mode of operation, the curved spine of the booklet protrudes a short distance beyond the jaws. The spine is then flattened by a forming roller which passes along the spine. In a second mode of operation, the spinal portion lies between the jaws and the curved end surface is flattened by the clamping force alone. The first mode is suited to booklets having or more sheets; the second to booklets having fewer than sheets or having loop staples and any number of sheets.
