A sheet processing apparatus includes a processing tray, a pushing member, and a movable guide. One or more sheets to be processed are placeable on the processing tray for sheet processing. The pushing member is configured to push an edge of the one or more sheets on the processing tray on an upstream side in a sheet conveying direction, by moving along a surface of the processing tray in the sheet conveying direction. The movable guide is movable to a sheet pressing position at which a distance between the surface of the processing tray and the movable guide is equal to or less than a height of the pushing member above the surface of the processing tray. The movable guide is at the sheet processing position when the pushing member moves along the surface of the processing tray in the sheet conveying direction.

A scanner for inserting a sheaf of papers into a file folder, which includes a first roller, a second roller, a third roller, and a fourth roller, each roller attached to a frame of the scanner, a first paper guide and a second paper guide attached to the frame of the scanner, a folder lifter attached to the frame of the scanner, a conveyor belt attached to the frame of the scanner, and a control circuit configured to control the scanner, where the first roller and the second roller are configured to feed a file folder toward the first paper guide, the first paper guide is configured to guide it toward the third and fourth rollers, where the first paper guide further guides the file folder onto the folder lifter, and the third and fourth rollers are configured to feed the file folder toward the second paper guide.

A sheet processing apparatus includes: a processing tray section having a sheet mounting surface on which a transported sheet is mounted and a processing section that performs processing on the sheet; a side edge alignment section that is provided on the processing tray section and aligns a side edge of the sheet; a lower support section that is provided downstream of the processing tray section in a transport direction of the sheet and supports the sheet from below; and a discharge tray located below the lower support section. The side edge alignment section performs a shift operation of shifting the sheet in a shift direction orthogonal to the transport direction of the sheet. The lower support section moves in the shift direction in conjunction with a movement of the sheet in a state of supporting the sheet from below during the shift operation by the side edge alignment section.

A sheet processing apparatus includes a conveyance unit configured to convey a sheet, a stacking portion on which the sheet conveyed by the conveyance unit is stacked, a first regulation member configured to regulate a position of an edge portion, in a conveyance direction, of the sheet stacked on the stacking portion, a second regulation member configured to regulate a position of an edge portion, in a width direction orthogonal to the conveyance direction, of the sheet stacked on the stacking portion, a binding unit supported movably in the conveyance direction and configured to perform a binding process of binding the sheet stacked on the stacking portion, and a moving unit configured to move the second regulation member in the conveyance direction accompanied with a movement, in the conveyance direction, of the binding unit.

A medium discharge includes a first tray having a first medium receiving surface, a second tray having a second medium receiving surface for receiving the medium discharged from the first tray, a discharge section that discharges the medium disposed on the first tray to the second tray, and a push-down portion that is located downstream of a downstream end of the first medium receiving surface in the medium discharge direction, and that is located at a place deviated from the discharge section in a width direction that is a direction intersecting with the medium discharge direction, and pushes down a part of an upstream end of the medium to be discharged in the medium discharge direction.

A separating element operates a transport device, which is configured to pile a plurality of partial book blocks for forming a book block along a book channel associated with the transport device, the finished piled book block being feedible to a processing machine. The book channel includes at least one transfer portion. At least one first separating element is arranged within the transport device as a link between an upstream transfer portion and a downstream transfer portion. The first separating element is configured to be operated by at least one drive and is configured to: receive a partial book block fed horizontally from the upstream transfer portion, horizontally transport the partial book block onward via the conveying portion formed by the first separating element, and then horizontally hand the partial book block over to the downstream transfer portion in keeping with a cycle.

A sheet processing apparatus for processing a sheet includes a conveying path in which a sheet is conveyed; a setting portion including an opening formed in a cover, a setting face supporting a lower face of a sheet bundle inserted through the opening from an outside of the sheet processing apparatus, and a regulating face which regulates a position of the sheet bundle; a stack portion on which sheets are stacked; a binding unit which is configured to bind a sheet bundle set on a sheet setting area; and a punching unit being configured to be movable in the sheet width direction, the punching unit including a punching portion which forms a punch hole. In the sheet width direction, the sheet setting area is arranged as being overlapped with a moving area of an end of the one side of the punching unit in the sheet width direction.

To enable a bunch of sheets to be reliably discharged to a stack tray, also in the case where weight of the bunch of sheets formed on a processing tray is large, upon receiving a printing command, a main body control section checks information on an ink discharge amount in printing on a sheet, the number of sheets, sheet type and printing mode (two-side/one-side). By this means, the section recognizes weight of the bunch of sheets formed on the processing tray, and when determining that the weight is heavier than predetermined weight, deceases an upper limit value of the number of sheets of a bunch of sheets formed at a time to report to a user.

A sheet processing apparatus includes a processing tray, a pushing member, and a movable guide. One or more sheets to be processed are placeable on the processing tray for sheet processing. The pushing member is configured to push an edge of the one or more sheets on the processing tray on an upstream side in a sheet conveying direction, by moving along a surface of the processing tray in the sheet conveying direction. The movable guide is movable to a sheet pressing position at which a distance between the surface of the processing tray and the movable guide is equal to or less than a height of the pushing member above the surface of the processing tray. The movable guide is at the sheet processing position when the pushing member moves along the surface of the processing tray in the sheet conveying direction.

An image forming system includes an image forming apparatus and a stacker that includes a discharged paper storage and a transporter, the discharged paper storage storing a sheet discharged from the image forming apparatus, and the transporter transporting the sheet to the discharged paper storage, wherein the image forming apparatus includes: an image former that forms an image on the sheet designated for a job and generates printed matter; and a hardware processor that performs control to cause the transporter to discharge a buffer sheet to the discharged paper storage, in which the printed matter is not discharged, before the job is executed, and that executes the job after the buffer sheet transported through the transporter is stored in the discharged paper storage to cause the transporter to transport the printed matter, which is generated by the image former, and cause the discharged paper storage to store the printed matter.
