摘要： When performing an alignment process on a sheet loaded on the processing tray in a state where a front end of the sheet is protruded from a discharge outlet above a discharge tray, the control unit performs a front end alignment process in which a pair of discharge tray cursors sandwich the front end of the sheet protruded above the discharge tray in the width direction, and a rear end alignment process in which the pair of processing tray cursors sandwich a rear end of the sheet on the processing tray in the width direction.

摘要： When discharging a sheet onto a discharge tray, a control unit sets position of the discharge tray in an up and down direction to a predetermined discharge position. When loading the sheet onto a processing tray, the control unit sets the position of the discharge tray in the up and down direction to a loading position lower than the discharge position.

摘要： A sheet transport device includes a delivery roller and a transport route. The transport route includes an upper guide member and a lower guide member. The lower guide member includes a first guide rib, a first corrugation member, and a first elastic member. The first elastic member supports an end portion of the first corrugation member on a side of the delivery roller, such that the end portion protrudes ahead of the first guide rib toward the upper guide member, with respect to the other end portion. The upper guide member includes a second guide rib, a second corrugation member, and a second elastic member. The second elastic member supports an end portion of the second corrugation member on the side of the delivery roller, such that the end portion protrudes ahead of the second guide rib toward the lower guide member, with respect to the other end portion.

摘要： 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.

摘要： 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.

摘要： 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

摘要： A postprocessing device includes a processing tray, a sheet processor, an air blower, an inlet roller pair, and a drive controller. The air blower forms an air layer between an upper face of a first recording sheet already placed on a loading surface of the processing tray, and a lower face of a second recording sheet to be newly placed on the processing tray, by sending air along a transport direction of the recording sheet, from an upstream side in the transport direction toward the loading surface. The drive controller performs an air sending operation, by causing the air blower to send air along the transport direction, before a second recording sheet contacts the upper face of the first recording sheet, and stop sending air before a trailing edge of the second recording sheet in the transport direction passes a nip region defined by the inlet roller pair.

摘要： A postprocessing device performs postprocessing on sheets received from an image forming apparatus. The postprocessing device includes a pair of folding rollers, a folding blade, a transport device, a drive portion, and a drive controller. The drive controller controls the drive portion to match moving speed of a tip portion of the folding blade with moving speed of a circumferential surface of the folding rollers, at a time point that the sheaf of the sheets makes contact with the circumferential surface of the folding rollers, when the image forming apparatus forms the image by ink jet printing, and to match the moving speed of the tip portion of the folding blade with the moving speed of the circumferential surface of the folding rollers, at a time point that the sheaf of the sheets reaches the nip region between the folding rollers.

摘要： A sheet post-processor of this disclosure is provided with a punching device and a registration roller. The punching device is capable of forming punch holes along a first side end edge of a sheet parallel to a sheet width direction orthogonal to a sheet conveyance direction and a second side end edge of the sheet parallel to the sheet conveyance direction. The registration roller is disposed downstream of the punching device in the sheet conveyance direction. The punching device includes a punch unit that forms punch holes through a sheet and an edge sensor that detects the second side end edge of a sheet. In a case of forming punch holes along the second side end edge of a sheet, without skewing of the sheet being corrected by the registration roller, the edge sensor detects the second side end edge, while the punch unit forms punch holes through the sheet.

摘要： A sheet loading device is provided with a sheet ejection portion, a sheet loading portion, a first detection mechanism, a driving device, a second detection mechanism, and a control portion. The driving device drives the sheet loading portion to ascend/descend between an upper surface detection position and a reference position made to descend by a prescribed distance from the upper surface detection position. The second detection mechanism detects that the sheet loading portion is at the reference position. In a case where sheets of the same type are ejected continuously from the sheet ejection portion, the control portion controls beforehand the sheet loading portion to ascend from the reference position to the upper surface detection position and sets a loadable number of sheets of the sheet loading portion in accordance with an ascending time of the sheet loading portion.
