Abstract: A post-processing apparatus includes a support member that supports a center-folded booklet by being inserted into the booklet along a fold of the booklet, a pair of clamp members that are disposed so as to face outer surfaces of the booklet supported by the support member and that clamp the booklet by moving closer to each other, and a post-processing mechanism that performs a post-processing operation on the booklet clamped by the pair of clamp members. The pair of clamp members clamp the booklet while moving relative to the booklet in a direction (up-down direction in the figure) so as to move away from the fold of the booklet, the direction being perpendicular to both of a clamp direction of the booklet and a direction in which the fold of the booklet extends.

Abstract: A sheet placement unit on which a plurality of sheet bundles having been produced by folding a plurality of sheets are stacked while being overlapped. The sheet placement unit includes a sheet placement section on which the folded sheet bundle having been provided with a folding process is loaded, the sheet placement section being inclined so that a downstream side of the sheet placement section in a sheet conveying direction is higher than another side, a sheet conveyance device to convey the sheet bundle loaded on the sheet placement section in a sheet conveying direction while the plurality of sheet bundles are overlapped, and a sheet holding device provided swingably above the sheet placement section, the sheet holding device comprising a sheet contacting section which comes in contact an upper surface of the sheet bundle loaded on the sheet placement section.

Abstract: The sheet processing apparatus processes a sheet having an image formed thereon by an image forming apparatus. The sheet processing apparatus includes a sheet folding unit for folding the sheet having an image formed thereon, a sheet tray loaded with the sheet folded by the sheet folding unit to be taken out, and a control unit for controlling the sheet processing apparatus as a whole. The sheet tray includes a mechanism capable of adjusting an angle with a virtual plane and a detection device detecting a change of the angle with the virtual plane. The control unit prohibits ejection from the sheet folding unit to the sheet tray, based on the detection result of the detection device and the content of the folding processing by the sheet folding unit.

Abstract: In a sheet finisher which receives a sheet from an image forming apparatus, conducts a sheet finishing onto the sheet and feeds out the sheet, the sheet finisher includes: a stacking section which stores temporarily one or more sheets; and a sheet finishing section which conducts the sheet finishing onto the sheet stored in the stacking section. The stacking section having a first guide member which forms a stacking surface to guide the sheet, and a second guide member which faces the first guide member and is spaced apart from the first guide member by a predetermined distance, and is provided obliquely from a horizontal direction, and the stacking surface formed by at least a part of the first guide member, is formed to be curved in a direction perpendicular to a sheet conveyance direction.

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: In a sheet post-finishing apparatus, a stapling device conducts a saddle stitching process on a bundle of sheets, based on an instruction signal; a sheet guide member, mounted on the stapling device, faces a surface of a sheet to be stacked on a sheet stacking section; a stapling device moving section allows the stapling device to move along a line dividing the sheet into two equal portions, perpendicular to a sheet conveyance direction; and a control section controls the stapling device to stand by above a lateral center of the sheet to be conveyed to the stapling device, while the sheets are stacked as the bundle of sheets, and after the bundle of sheets is formed, the control section controls the stapling device to sequentially move to predetermined plural positions, whereby said control section sends the instruction signal to the stapling device which was stopped at the predetermined positions.
