Abstract: A sheet conveying device has a body and a frame supporting it, and is insertable or extractable along a sheet stacking face formed in an in-body discharge space in an image forming apparatus and having an inclined face with an upward gradient toward the downstream side in the sheet discharge direction. On the face of the frame opposite the sheet stacking face, a plurality of first and second wheels rotatable in the insertion or extraction direction are provided downward of the center of the opposite face in the insertion direction. The first wheels are arranged downstream of the second wheels in the insertion direction, and protrude from the opposite face farther than the second wheels. The first wheels fit into a concave portion formed in the sheet stacking face by the inclined face and thereby enable the second wheels to make contact with the sheet stacking face.

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: An image forming system includes an image forming apparatus, a first conveyance path, a sheet feeding unit, a sheet post-processing unit, and a controller. The image forming apparatus has a first feed portion, and an image forming portion. The sheet feeding apparatus has a sheet stacking portion, a second feed portion, a relay conveyance portion, and a remaining amount detecting portion. When, during continuous printing, the existing number of recording sheets present in a conveyance passage from a confluence portion to the first feed portion is more than the constituting number of recording sheets contained in one bundle of sheets and in addition the sensing result of the remaining amount sensor is equal to or less than a predetermined amount, the controller controls first feed portion such that the existing number of the recording sheets is less than the constituting number of recording sheets.

Abstract: A sheet feeding apparatus includes a sheet stacking portion, a lift plate, an actuating segment, driving unit, a sheet feeding portion, a first detecting portion, a remaining amount detection portion. The remaining amount detection portion includes a detection piece, a link mechanism, a second detecting portion, a controller. The link mechanism couples together the driving shaft and the detection piece at a coupling position attained by pivoting the lift plate through a predetermined angle from a lower limit position in rotation direction, so as to let the driving shaft and the detection piece rotate together. The second detecting portion senses whether or not the detection piece is present. The controller determines the remaining quantity level of the stacked sheets according to whether or not the second detecting portion is detecting the detection piece being present.
