Sheet feeder (4) for a machine (1) for the processing of sheet material such as paper or films, having a drive shaft (10), which extends substantially perpendicular to a sheet feeding direction and is provided with at least one suction gripper (12), which is rotated above the sheet material, when the drive shaft (10) is driven, wherein the suction gripper (12) is repositionable between an inactive position, in which it does not cooperate with the sheet material, and an active position, in which it can grip on the top side of the sheet material and carry this along.

A sheet processing apparatus is provided with a carry-in path for guiding a sheet from a carry-in entrance, a shift roller provided in the carry-in path to transport the sheet, while shifting, a carry-in roller positioned on the downstream side of the shift roller to carry the sheet from the carry-in path toward a collection tray, and a punch shift unit provided on the upstream side of the carry-in roller to process an end portion of the sheet in a processing position. The punch shift unit shifts in the same direction as the shift roller, a shift amount of the punch shift unit is set to be equal to a shift amount of the shift roller or more, and the end portion processing unit is thereby already positioned in an end portion processing position or a position near the processing position after shifting the sheet.

A driving device includes a motor, a drive gear, a swing gear, a first gear member, a second gear member, a frame, and a bracket. The swing gear can swing between a first position engaging with the first gear member and a second position engaging with the second gear member. The bracket has a slide hole including a pair of contact parts having an arc shape, and an arc hole part for connecting the pair of contact parts with a first sliding surface farther from the drive gear and a second sliding surface nearer to the drive gear. The first sliding surface has a shape retracting to the opposite side to the rotation shaft from tangential lines of the rotation shaft contacting with the contact parts, which are parallel to pressure angle directions between the drive gear and the swing gear, or a shape coinciding with the tangential lines.

A sheet container includes a bottom plate, a regulating body, and a holding body. The bottom plate is disposed movable and has a bottom plate-side contact portion. The regulating body regulates a position of a trailing end of a sheet. The holding body has a holding body-side contact portion and to hold the regulating body. The bottom plate and the holding body have a gap between the bottom plate-side contact portion of the bottom plate and the holding body-side contact portion of the holding body in a state in which the bottom plate is not rotated. The bottom plate-side contact portion of the bottom plate and the holding body-side contact portion of the holding body contact with each other along with rotation of the bottom plate. The holding body moves to a downstream side in a sheet feeding direction in conjunction with the rotation of the bottom plate.

A manual tray device comprises a tray storage body; a tray main body rotatably supported on the tray storage body with a lower end side as a rotation fulcrum; an assistance tray arranged at an upstream side of the tray main body in a sheet feed direction; a rotation regulation link, one end part side of the rotation regulation link being rotatably supported on the tray storage body, the other end part side being slidably supported on the tray main body in a predetermined stroke range; and an interlocking mechanism configured to interlock displacement of the other end part side of the rotation regulation link with forward and backward displacement of the assistance tray. The assistance tray protrudes from the tray main body in a state where rotation of the tray main body in the opening direction is regulated by the rotation regulation link.

Embodiments provide methods, apparatuses, and systems for compressing media in a media stack. In various embodiments, a paddle moves between various positions. During the move, the paddle is configured to compress the media stack.

In accordance with an embodiment, an image processing apparatus comprises a sheet feed cassette, an operation lever, a sliding section, a sheet lifting and lowering tray, and a main body rail section. The sheet feed cassette is housed to be capable of being pulled out from an apparatus main body. The operation lever is arranged at the side of the sheet feed cassette and is rotatable around a shaft positioned at the middle in a longitudinal direction. The sliding section is arranged at the rear side of the shaft of the operation lever. The sheet lifting and lowering tray can place a sheet and adjust an inclination thereof in conjunction with the operation lever. The main body rail section is arranged in the apparatus main body and guides running of the sliding section at the time of pulling out the sheet feed cassette.

A delivery mechanism of business machine including a carrier board, an assembly rack, a delivery wheel group and at least one linkage assembly is provided. The assembly rack is disposed above the carrier board. The delivery wheel group includes at least one first roller and at least one second roller. The first roller is disposed on the carrier board. The second roller is disposed on the assembly rack and leans on the first rollers. The linkage assembly includes a rotation member and a paper flattening member. The rotation member is pivotally disposed on the assembly rack. The two opposite ends of the paper flattening member are respectively disposed at the rotation member and the assembly rack, such that the paper flattening member can be displaced along a curved path.
