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: A postprocessing device includes a pair of folding rollers, a folding blade, a transport device, a roller driver, a blade driver, and a drive controller. The drive controller selectively performs one of a first rotation control, including controlling the roller driver to keep rotation speed of the pair of folding rollers constant, while the folding blade is moving away from a nip region, and a second rotation control, including controlling the roller driver to stop the rotation or slow down the rotation speed of the pair of folding rollers, while a tip portion of the folding blade is being withdrawn from a folded portion of a sheaf of sheets folded, and to restore the rotation speed of the pair of folding rollers to original rotation speed, after the tip portion of the folding blade has been removed from the folded portion of the sheaf of sheets folded.

Abstract: A postprocessing device is attached to an image forming apparatus. The postprocessing device includes a processing tray, a sheet processor, and a fan. The processing tray is for stacking thereon sheets on which an image has been formed and which is transported from the image forming apparatus. The sheet processor performs predetermined postprocessing on the sheets stacked on the processing tray. The fan forms an air layer between an upper face of the sheets already stacked on the stacking surface of the processing tray and a lower face of a sheet newly placed on the processing tray, by emitting air in a transport direction of the sheet, from an upstream side in the transport direction toward the stacking surface.

Abstract: A post-processing device includes a carrying roller, a conveying member, a transporting member and a processing part. The carrying roller is configured to be rotated to carry a sheet one by one to a processing tray along a conveyance direction. The conveying member is configured to convey the sheet carried by the carrying roller to a receiving position on the processing tray. The conveying member has a rotation shaft and a plurality of contact pieces protruding from the rotation shaft so as to come into contact with the sheet carried on the processing tray. The contact piece is made of elastic material. The conveying member is rotated at a rotation speed higher than a rotation speed of the carrying roller when the sheet carried by the carrying roller is conveyed to the receiving position on the processing tray.

Abstract: A sheet stacking device includes a sheet stacking section, pairs of ejection rollers, an airflow generator, and an airflow guide. The airflow guide has a center exhaust port and paired side exhaust ports. An airflow is blown out from the center exhaust port toward a central part of the lower surface of the sheet in a sheet width direction perpendicular to a conveyance direction of the sheet. Airflows are blown out from the respective paired side exhaust ports toward respective sides of the lower surface of the sheet. An amount of the airflow blown out from the center exhaust port is larger than those of the airflows blown out from the respective paired side exhaust ports.

Abstract: A sheet post-processing device comprises: a processing tray; a discharge tray; and a discharge rollers pair. The discharge rollers pair is constituted by a discharge roller which contacts the uppermost surface of sheets stacked in the processing tray and a discharge roller which contacts the lowermost surface of the sheets stacked in the processing tray). The sheet post-processing device discharges a sheet from the processing tray to the discharge tray by rotating the discharge rollers pair in the forward direction, and causes the sheet to be drawn into the processing tray by rotating the discharge roller in the reverse direction in a state in which the rotation of the discharge roller is stopped.

Abstract: A post-processing unit in an image forming apparatus includes a stapler, an exit tray, a height detector, and a shifting controller. The stapler staples a sheet sheaf. The exit tray is configured to be elevated and lowered and to receive the sheet sheaf stapled by the stapler. The height detector detects a height of the sheet sheaf on the exit tray. The shifting controller shifts the sheet sheaf to be ejected in a situation in which the stapler staples one location at a trailing end of the sheet sheaf in a conveyance direction of the sheet sheaf. The shifting controller shifts the sheet sheaf in a front-rear direction, which is a direction perpendicular to a vertical direction and to the conveyance direction of the sheet sheaf, so that the stapled location in the sheet sheaf on the exit tray matches a detection point of the height detector.

Abstract: A sheet processing device includes an exit tray and a sheet alignment mechanism. On the exit tray, ejected sheets or ejected sheet sheaves subjected to stapling are stacked. When at least a sheet is ejected, the sheet alignment mechanism aligns the sheets in a manner to be in contact with and catch opposite ends of the sheets stacked on the exit tray from a base end side of the exit tray. When a sheet sheaf is ejected, the sheet alignment mechanism comes in contact with a plurality of points on a topmost surface of the sheet sheaves stacked on the exit tray to detect a height difference between the plurality of points.
