Abstract: A sheet ejection device includes an ejection roller pair, a stacking tray, a protrusion member and a movement mechanism. The protrusion member is supported to be able to reciprocate between a protrusion position and a retraction position in a predetermined movement direction. The movement mechanism includes: a rotation shaft; a holding member; and a rack and pinion mechanism which includes a pinion gear and a rack gear. In at least a part of the rack gear in the movement direction, a narrow width region is provided which includes a narrow width gear and a cutout portion. In the narrow width region, the pinion gear is slidable between a meshing position and a release position, and in a state where the pinion gear has slid to the release position, the protrusion member can be relatively moved with respect to the pinion gear in the movement direction.

Abstract: A sheet conveyance device includes a sheet receiving part, a first discharge part, a sheet conveyance path, an escape conveyance path, a branch guide, an escape tray, a second discharge part, and a first sheet detection part. When a device failure occurs, the branch guide switches the conveyance direction such that the sheet remaining on the sheet conveyance path is discharged on the escape tray by the second discharge part, through the escape conveyance path sequentially. Then, the second discharge part stops a discharging of the sheet in a state where the sheet remains in the second discharge part when the sheet is a last sheet to be conveyed to the escape tray. Then, a receiving of a new sheet to the sheet receiving part from the image forming apparatus is inhibited while the first sheet detection part detects the last sheet.

Abstract: The sheet discharge device includes a sheet discharge port, a discharge member, a sheet discharge tray, and a blower mechanism. The sheets discharged through the sheet discharge port by the discharge member are stacked on the sheet discharge tray. The blower mechanism includes an air blow hole for blowing off an air flow from upward to the sheets discharged through the sheet discharge port, and a blower device coupled to the air blow hole to generate the air flow. The air blow hole, being provided upward of the sheet discharge port, is placed in at least one pair or more on both sides of a center of the sheet in its widthwise direction perpendicular to the discharge direction, and the air flow derived from the air blow hole is blown off diagonally downward from outside to inside of the widthwise direction.

Abstract: The sheet postprocessing device includes a conveyance member, a processing tray, a processing part, a discharge member, a sheet discharge tray, a support member, a drive mechanism, and a controller. The sheet discharge tray is placed on a downstream side of the processing tray in a discharge direction, and the sheet discharged from the processing tray is to be stacked. The support member is movable by the drive mechanism between a projective position in which the support member is projected from a downstream-side end portion of the processing tray in the discharge direction, to above the sheet discharge tray so as to support part of the sheet carried in onto the processing tray, and a retractive position in which the support member has retracted to an upstream side of the discharge member in the discharge direction. The controller is enabled to adjust the projective position of the support member.

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, and an alignment paddle having a paddle main body supported in a rotatable manner at the paddle holder, and a paddle part protruding from the paddle main body. The holder drive unit moves the alignment paddle in a reciprocating manner, between a reference position to separate the paddle part above a top sheet and an acting position to allow the paddle part to contact with the top sheet. The control unit sets a second acting position when the paddle part contacts with the sheet at n1-th time, to be higher than a first acting position when the paddle part contacts with the sheet at m1-th time, where 1≤m1

Abstract: A sheet postprocessing apparatus includes a table configured to receive a plurality of sheets delivered thereto, and inclined downward toward a downstream side in a sheet delivery direction, a leading edge cursor provided on a far side on the table in the delivery direction, and configured to align respective leading edges of the sheets abutted against the leading edge cursor, and a postprocessing device including a stapling device that binds a central portion in the delivery direction, of the sheets stacked on the table, and a center folding device that folds the sheets along the central portion. The table includes an upper face region that allows the sheet to slide thereon, and a plurality of slip sheets of a belt-like shape, each extending on the upper face region along the delivery direction, with a clearance between each other in a width direction orthogonal to the delivery direction.

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.
