A sheet bundle discharging apparatus, including: a guide unit configured to guide a sheet bundle with a spine as a leading end; a receiving unit configured to receive the spine of the sheet bundle guided by the guide unit; and a discharging unit configured to discharge the sheet bundle, wherein the receiving unit includes: a first surface configured to receive the spine at a first position; a second surface configured to push the sheet bundle in a rotation direction of the receiving unit; and a third surface configured to regulate a movement of the sheet bundle in the rotation direction while the receiving unit rotates from the first position to a second position, and wherein a friction coefficient between the sheet bundle and the third surface in a direction away from the first surface is larger than a friction coefficient between the first surface and the sheet bundle.

A sheet processing apparatus includes alignment plates, which are provided outside a main body housing of a sheet processing apparatus, shift in an alignment direction orthogonal to a transport direction of a sheet loaded on a load tray to load sheets discharged from a discharge opening, and align opposite sides of the sheet, and a sheet support surface provided in a different position adjacent to a processing tray in the alignment direction to support sheets inserted from a manual feed opening provided outside the main body housing. A binding apparatus shifts to the processing tray or the sheet support surface, and binds sheets placed on the processing tray or the sheet support surface. Neat alignment plates are positioned not to block the manual feed opening during the binding processing on manually fed sheets on the sheet support surface.

A bookmaking system includes sets of redundant cover printers and book block printers and a binder (or set of binders) for binding a printed cover page, printed by an assigned one of the set of redundant cover printers, and a corresponding set of printed pages for a book block, printed by an assigned one of the set of redundant book block printers, together to form a book. A transport mechanism connects the redundant printers and redundant cover printers with the binder. An assigned one of a plurality of book block buffers, intermediate the book block printers and the binders, stores the set of printed pages until the corresponding printed cover page is ready for binding; and/or an assigned one of a plurality of cover buffers, intermediate the cover printers and the binders, stores the printed cover page until binding can be performed.

Apparatuses, systems, and methods are provided for print media buffering and sorting. An apparatus for performing at least one of buffering and sorting during an operation includes a storage section, an input section configured to receive at the storage section at least a portion of a printed element, a gripper associated with the input section, the gripper configured to selectively transport the at least a portion of the printed element from the input section to the storage section and to selectively transport the at least a portion of the printed element from the storage section, and an output section configured to selectively transfer the at least a portion of the printed element from the storage section.

A method for processing a sheet for bookbinding includes operations. A cut is formed that divides a thickness of the sheet in a binding-side side surface of the sheet. A portion of a connection piece that is attached to the sheet is inserted into the cut as an inserted portion, and functions as a hinge in a book-bound state. The portion of the connection piece inserted into the cut is joined to the sheet.
