摘要： A loading unit includes a processing tray, alignment units, and a paddle. In the processing tray, a medium is placed. The alignment units are disposed an interval in a Y direction to align a downstream tip end in a positive A direction of the medium. The paddle moves the medium that has been fed onto the processing tray toward the alignment units. A coefficient of friction of a contact surface of the alignment unit is higher than a coefficient of friction of a front face of the alignment unit, and the contact surface is positioned downstream of the front face in the positive A direction.

摘要： A sheet post-processing apparatus that performs post-processing on a sheet on which an image is formed includes: a punch hole forming portion; and a sheet bundle forming portion that has a conveyance portion, stops a first sheet on a conveyance path, and conveys a second sheet after the first sheet to a position overlapping the first sheet to form a sheet bundle. The sheet post-processing apparatus includes a shift portion to make a shift so that a relative position between the first sheet and the second sheet in a direction orthogonal to a conveyance direction becomes a relative position at which the second sheet does not overlap a punch hole of the first sheet to make the second sheet overlap the first sheet, and forms a sheet bundle in which sheets overlapped with each other are deviated in a width direction.

摘要： A sheet post-processor includes a processing tray, a sheet discharge port, a discharge roller pair, a pair of cursor members, a pair of support members, and an interlocking mechanism. The interlocking mechanism includes a pair of coupling members arranged in the processing tray so as to be reciprocatable in a sheet width direction. The pair of coupling members are coupled to or decoupled from the pair of cursor members in accordance with movement of the pair of cursor members. While being coupled to the pair of cursor members, the pair of coupling members contact the pair of support members so as to displace the pair of support members to a protruding position, and while being decoupled from the pair of cursor members, the pair of coupling members separate from the pair of support members so as to displace the pair of support members to a retracted position.

摘要： A sheet stacking device includes a pair of first sheet stackers, a pair of sheet alignment members, a second sheet stacker, a sheet removal portion, and control circuitry. The first sheet stackers stack both end portions of a sheet in a direction orthogonal to a sheet ejecting direction. The sheet alignment members contact both ends of the sheet in the orthogonal direction to align the sheet on the first sheet stackers. The second sheet stacker is disposed lower than the first sheet stackers and stacks the sheet dropped from between the first sheet stackers. The sheet removal portion is disposed on one side in the orthogonal direction. The control circuitry causes one of the first sheet stackers and one of the sheet alignment members to move toward an opposite side of the sheet removal portion in the orthogonal direction after the sheet is dropped from between the first sheet stackers.

摘要： An image forming apparatus includes a processing tray, a post-processing controller, and a detection sensor. The processing tray is configured to support a sheet or a sheet bundle on which a post-processing is to be executed. The post-processing controller is configured to execute the post-processing on the sheet positioned on the processing tray. The detection sensor is configured to detect an object in a predetermined detection range including a space above the processing tray. The post-processing controller stops execution of the post-processing when the detection sensor detects the object at a determination timing other than a timing at which passage of the sheet or the sheet bundle through the detection range is estimated.

摘要： A medium ejection apparatus includes a placement mount on which media are placed, a restriction part that moves between a restriction position at which the restriction part restricts media ejected toward the placement mount and a retracted position retracted from the restriction position, and a processor that controls the restriction part by adjusting a restriction frequency on the basis of at least either an amount of movement of the restriction part from the retracted position to the restriction position or ejection intervals at which the media are ejected toward the placement mount, the restriction frequency being a frequency with which the restriction part performs a restriction operation for the media.

摘要： A sheet processing apparatus includes a conveyance member to convey a sheet, a pair of alignment members to move relatively in a width direction orthogonal to a conveyance direction of the sheet by the conveyance member, so as to align a position of the sheet in the width direction, and a lower portion to support a lower surface of the sheet between the pair of alignment members in the width direction. In addition, a pair of upper portions are arranged on one side and the other side of the lower portion in the width direction and each hold an upper surface of the sheet, wherein the pair of upper portions is positioned lower than the lower portion in a plane vertical to the conveyance direction.

摘要： A medium transport device includes a lower guide member, a processing tray, a feeding section, and a notch. The lower guide member supports a medium transported and guides the medium toward the processing tray. The processing tray includes an alignment member, and a plurality of media are stacked in the processing tray. The feeding section includes a paddle member having a rotation center between the processing tray and the lower guide member such that a rotation locus of a distal end intersects the lower guide member, and the feeding section is configured to feed the medium toward the alignment member. The lower guide member has a notch, and an upstream end of the notch in the transport direction is formed at a position inside the rotation locus in the lower guide member.
