Abstract: A sheet post-processing apparatus includes a first conveying member, a processing tray, a first processing unit, a reference plate, an alignment member, a home-position detection unit, a drive unit, and a control portion. The alignment member has a shaft joined to a drive unit to rotate, and one or more alignment paddles protruding in a radial direction of the shaft. The control portion calculates a contact assumed interval in which the trailing end of the sheets may make contact with the alignment paddle and an interference timing at which the alignment paddle interferes with a carry-in path of the sheets. If the interference timing falls within the contact assumed interval, the control portion temporarily changes the rotation speed of the alignment member from a reference speed to shift the phase of the alignment paddle so that the interfere timing falls outside the contact assumed interval.

Abstract: 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.

Abstract: 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.

Abstract: A sheet postprocessing device includes a sheet conveying passage, a sheet tray, an inlet guide, a processing device, and a blowing device. Though the sheet conveying passage, a sheet on which an image has been formed is conveyed. The sheet tray is arranged downstream of the sheet conveying passage and has sheets stacked on it. The inlet guide is arranged at the downstream end of the sheet conveying passage and guides a sheet to the sheet tray. The processing device performs predetermined processing on a sheet stacked on the sheet tray. The blowing device blows air, from the upstream side in the sheet conveying direction, between the top face of the top-most sheet in the sheets stacked on the sheet tray and the bottom face of the subsequent sheet sent from the inlet guide into the sheet tray.

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: A sheet post-processing apparatus successively performs: a control in a first mode to move a pair of side end cursors to respective first positions where edges of the side end cursors facing a tray come into contact with an ejected sheet above and away from the tray and move the side end cursors to respective holding positions located inwardly of the sheet in a width direction; and a control in a second mode to move the side end cursors to respective lateral positions located outwardly of the sheet in the width direction, move the side end cursors to respective second positions where the edges of the side end cursors facing the tray come close to or into contact with the tray, and move the side end cursors from the lateral positions to respective abutment positions where the side end cursors abut against ends of the sheet in the width direction.

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.
