Abstract: 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.

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: 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 discharge device includes a discharge member, a discharge tray and a stopper. The discharge tray includes a groove and a fixed magnetic body. The groove is formed along a discharge direction. The fixed magnetic body is disposed at a predetermined position along the groove. The stopper includes a guide piece, a contact piece and a moving magnet body. The guide piece is engaged with the groove in a slidable manner. With the contact piece, the leading edge of the sheet is allowed to be come into contact. The moving magnetic body generates a magnetic force in a direction in which the moving magnetic body and the fixed magnetic body are attracted each other. When the guide piece is slid along the groove and the moving magnetic body reaches the predetermined position, a resistance is applied to a sliding movement of the guide piece by the magnetic force.

Abstract: A sheet conveying device has a supporting frame that supports a pick-up roller and that moves downward when a sheet is fed, a stepping motor that rotates the pick-up roller and moves the supporting frame downward, and a control portion that starts driving the stepping motor when a job is started and then increases a frequency of the pulse signal to a target frequency. The control portion keeps the frequency of the pulse signal not more than ½ of the target frequency at least until the pick-up roller touches the sheet first.
