摘要:
A sheet handling apparatus (PD) includes a sheet reception unit (F) configured to receive a sheet; an alignment unit (51a, 51b) configured to align the sheet in a conveying direction of the sheet, a trailing edge of the sheet in the conveying direction coming into contact with the alignment unit (51a, 51b); and a moving unit configured to move the alignment unit (51a, 51b) along the sheet reception unit (F) in the conveying direction. A first position for aligning and binding sheets and a second position located above the first position in the sheet reception unit (F) are set for the alignment unit (51a, 51b) as receiving positions at which the sheet is received from the sheet reception unit (F).

A pressing unit presses a folded side of a stack of sheets folded by a folding unit (74, 81), thereby making a strong crease on the stack of sheets. The pressing unit includes a pressure roller (600) that slides on the folded side while rotating, an elastic biasing unit (609) that presses the pressure roller (600) in a thickness direction of the stack of sheets, and a driving unit (606, 607, 612) that slides the pressure roller (600) in a direction substantially perpendicular to a conveying direction of the stack of sheets. A lifting unit (602, 611), when the pressure roller (600) slides to a first position, temporarily lifts up the pressure roller (600), and when lifted-up pressure roller (600) slides to a second position, lifts the lifted-up pressure roller (600) down onto the folded side. The first position and the second position are located before a corner of the folded side, whereby the pressure roller (600) cannot slide up on the folded side.

A sheet conveying device includes a first conveying path (2b,2c) configured to pass a paper sheet therethrough to a sheet processing device, a second conveying path (2d) branched from the first conveying path and configured to temporarily store the paper sheet conveyed therein, a sheet conveying mechanism (6,7) configured to selectably convey the paper sheet in one of forward and backward directions to the sheet processing device, a guide member (9) mounted at a branch point of the first and second conveying paths and configured to guide the paper sheet when the paper sheet is conveyed in the backward direction by the sheet conveying mechanism to the second conveying path, and a control unit configured to control the sheet conveying mechanism to change a distance between the branch point and the sheet conveying mechanism according to a length of the paper sheet in a forward sheet conveying direction.
摘要:
A sheet processing apparatus (100) includes: first to third pairs of conveying members (R1; R1a, R1b: Rt2; R3, R4: Rt2; R3, R4); and a bifurcating claw (B) that moves to a first guiding position for guiding the sheet (P) to the second pair of conveying members (Rt1; R2, R3), a second guiding position for guiding a deflected portion of the sheet (P) to the third pair of conveying members (Rt2; R3, R4), and a third guiding position for guiding a leading end of the sheet (P) to the third pair of conveying members (Rt2; R3, R4). The second pair of conveying members (Rt1; R2, R3) is rotated backward in a state in which the sheet (P) is held by the first pair of conveying members (R1; R1a, R1b) and the second pair of conveying members (Rt1; R2, R3), to guide the deflected portion to the third pair of conveying members (Rt2; R3, R4) and cause the deflected portion to be folded by the third pair of conveying members (Rt2; R3, R4).
摘要:
A sheet alignment device, that is included in a sheet finishing apparatus (PD1, PD2) integrally mounted with an image forming apparatus to an image forming system (1000) or connected to the image forming apparatus, includes an accommodating unit (434, F) configured to temporarily accommodate a paper sheet (S) and a paper sheet stack including the paper sheet (S) therein, and a sheet alignment unit configured to align the sheet stack including the paper sheet in a direction perpendicular to a sheet travel direction. The sheet alignment unit has a first alignment member (53a) configured to move between a sheet receiving position and a sheet alignment position along the direction perpendicular to the sheet travel direction to push the sheet stack and a second alignment member (53b) configured to move to a fixed position and remain stationary thereat so as to stop the sheet stack pushed by the first alignment member (53a).
摘要:
A perforating apparatus (100) comprising a structure in which replacement can be easily conducted corresponding to the perforation conditions such as the punch holes and number of holes, and in which condition settings and position determination can be automatically recognized during replacement; the perforating apparatus comprises a perforation device comprising a punch (8) to conduct perforation processing on the paper; the perforating apparatus (8) comprising a structure (32, 33) in which said perforation device can be inserted into and detached from a non-moving support unit (33) comprising the drive source of a lateral registration adjustment device (38), and when mounted, the type of perforation device can be recognized.
摘要:
A sheet processing apparatus (100) includes: a first conveying member pair (2; R3, R4) that folds a sheet; a second conveying member pair (3, R6; R6a, R6b) that conveys downstream the sheet folded by the first conveying member pair (2; R3, R4); and a third conveying member pair (4; R3, R5) that further folds the sheet folded by the first conveying member pair (2; R3, R4). The second conveying member pair (3, R6; R6a, R6b) is rotatable forward and reversely when driven to convey, and is locked in one rotational direction but is rotatable in the other rotational direction when not driven.
