Abstract: A sheet postprocessing device includes a saddle binding device configured to stack a plurality of recording sheets on a table, abut leading edges of the respective recording sheets against a leading edge cursor, thus to align the leading edges with each other, and bind the center of the recording sheets and fold the recording sheets, and a first pressing member supported so as to pivot in a direction toward and away from the table. The first pressing member is made to pivot toward the table by self-weight thereof, allows the leading edge of the recording sheet delivered to the table to pass toward the leading edge cursor, and presses a portion of the recording sheet in a proximity of the leading edge, at a position upstream of the leading edge cursor, in a delivery direction of the recording sheet.

Abstract: A sheet discharger includes a sheet discharge outlet, a discharge member, a sheet discharge tray, a sheet hold-down member, a drive portion, and a control portion. The sheet discharge tray is disposed downstream from the sheet discharge outlet with respect to a discharge direction and is a tray on which a sheet discharged through the sheet discharge outlet is loaded. The sheet hold-down member is swingable between a hold-down position at which the sheet loaded on the sheet discharge tray is held down at an upstream part thereof in the discharge direction and a retracted position retracted upward from the hold-down position. The drive portion drives the sheet hold-down member. The control portion determines, in accordance with characteristics of the sheet, whether or not to execute a sheet hold-down operation in which the sheet hold-down member is moved to the retracted position and to the hold-down position.

Abstract: The sheet discharge device includes a sheet discharge port, a discharge member, a sheet discharge tray, a support member, a drive mechanism, and a controller. The discharge member conveys sheets in a discharge direction. On the sheet discharge tray, the sheets discharged from the sheet discharge port are to be stacked. The support member is movable by the drive mechanism between a projective position in which the support member is projected to above the sheet discharge tray so as to support the sheets, and a retractive position in which the support member has retracted from the projective position to an upstream side of the sheet discharge port. The controller is enabled to adjust at least one of a projective length of the support member in its projective position and a shift timing from the projective position to the retractive position in response to characteristics of the sheets.

Abstract: Provided is a sheet post-processing apparatus in which a control portion repetitively performs a width-direction alignment operation including a first alignment operation of moving width regulating members from standby positions to first regulating positions after a sheet that is carried in onto a processing tray has been aligned in a carry-in direction by abutting of an edge of the sheet against a reference plate, and a second alignment operation of moving the width regulating members from the first regulating positions to the standby positions after performing the first alignment operation, and then moving the width regulating members to second regulating positions. The sheet post-processing apparatus satisfies C1>C2>P1≥C3 where P1 is a size in a width direction of the sheet, and C1, C2, and C3 are intervals between the width regulating members at the standby positions, the first regulating positions, and the second regulating positions, respectively.

Abstract: Provided is a sheet post-processing apparatus in which a control portion repetitively performs a width-direction alignment operation including a first alignment operation of moving width regulating members from standby positions to first regulating positions before a sheet that is carried in onto a processing tray is aligned in a carry-in direction by abutting of an edge of the sheet against a reference plate, and a second alignment operation of moving the width regulating members from the standby positions to second regulating positions after the sheet has been aligned in the carry-in direction by the reference plate. The sheet post-processing apparatus satisfies C1>C2>P1≥C3 where P1 is a size in a width direction of the sheet, and C1, C2, and C3 are intervals between the width regulating members at the standby positions, the first regulating positions, and the second regulating positions, respectively.

Abstract: The sheet postprocessing device includes a sheet conveyance path, a sheet tray, a carry-in guide, a processing part, a discharge member, a blower device, and an intermediate conveyance part. The sheet tray includes an upstream-side stacking part. The intermediate conveyance part is provided at a position within a range from the upstream-side stacking part to the downstream-side stacking part in a conveyance direction, and allows a sheet to pass therethrough below the processing part. The intermediate conveyance part is made up by including an upstream part including a first clearance through which the sheet passes, and a downstream part placed on a downstream side of the upstream part and including a second clearance through which the sheet passes. A size of the second clearance in a planar direction perpendicular to a surface of the sheet is wider than a size of the first clearance in the planar direction.

Abstract: A sheet post-processing device includes a conveying member, a processing tray, a processing section, a reference plate, an alignment member, a holder drive unit, and a control unit. The alignment member includes a paddle holder supported in a swingable manner along a carry-in direction, and an alignment paddle supported in a rotatable manner at a swinging end of the paddle holder. The holder drive unit moves the alignment paddle in a reciprocating manner, between a reference position to retreat the paddle part above a top sheet placed on the processing tray and an acting position to allow the paddle part to contact with a top surface of the sheet. When the number of the sheets carried in onto the processing tray is increasing, the control unit continuously moves the acting position of the alignment paddle in a direction separating from the processing tray.
