A sheet bundle discharging apparatus including: a conveyance belt configured to convey and discharge a sheet bundle in a conveyance direction; an attitude changing unit configured to change an attitude of the sheet bundle from a first attitude in which the sheet bundle is apart from the conveyance belt to a second attitude in which the sheet bundle is placed on the conveyance belt; and a receiving member configured to receive an end portion of the sheet bundle, wherein the attitude changing unit allows the end portion of the sheet bundle to pass through a region in which the conveyance belt is provided, in a belt width direction perpendicular to the conveyance direction, and thereafter reach a region in which the receiving member is provided, a friction coefficient between the sheet bundle and the receiving member being smaller than a friction coefficient between the sheet bundle and the conveyance belt.

The device includes a first conveyor 1 and a second conveyor 12. The first conveyor transports the book blocks B to the bookbinding apparatus and can accumulate the book blocks on a transport surface 4. A first stopper 23 is arranged at an entrance of the second conveyor and a second stopper 28 is arranged in the middle of a path of book block on the transport surface of the first conveyor. The first and second stoppers can take a block position and a retracted position. The second conveyor and the first stopper operate in synchronization with an operation of the bookbinding apparatus. The second stopper takes the block position when the number of book blocks accumulated on upstream side of the first stopper exceeds a predetermined limit value, or when a thickness difference between the book blocks transported side by side exceeds a predetermined reference value.

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.

A paper stack S supplied between clamping plates 1a, 1b of a carriage clamp 1 is pushed toward a positioning bar 2b by an alignment bar 5. A nip head 7 of a paper stack supplying unit 3 has first and second nip plates 9, 10, and a nip plate drive mechanism 11 moving each nip plate from a protruding position at which the nip plate protrudes from the nip head and a retracted position at which the nip plate retracts into the nip head, and translating the second nip plate taking the protruding position relative to the first nip plate taking the protruding position between a first position at which the first and second nip plates receive the paper stack therebetween and a second position at which the second nip plate cooperates with the first nip plate to grip the paper stack.

In case of simultaneously performing a punching process and a finishing process other than the punching process in an image forming apparatus, in order to prevent an unnecessary (ineffectual) finishing process from being performed, an information processing controller unit of a multifunction peripheral performs control of permitting to set in combination a double-punching center setting and a bookbinding setting, and of prohibiting to set in combination a punch setting, other than the double-punching center setting, and the bookbinding setting.

A printing system includes a book body printing section including a book body printing machine and outputting book bodies sequentially, and a cover printing section including a cover printing machine and outputting covers sequentially. The book body printing machine and the cover printing machine respectively receive printing order data indicating a printing order with regard to a plurality of jobs from a print control apparatus, and perform printing in the printing order indicated by the printing order data. The print control apparatus generates the printing order data, so that an inserting order in unit of job to a bookbinding machine of the book bodies output from the book body printing section coincides with an inserting order in unit of job to the bookbinding machine of the covers output from the cover printing section.

The present invention relates to round corner cutting machine that comprises 5 pairs of suckers (116), each pair of sucker (116) grips single book and middle sucker (116) being located between pairs of sucker (116) that grip middle book. Here, position of each pair of sucker (116) is adjusted by adjusting position of guide blocks though adjustable links (107, 108). Further, distance between suckers (116) of each pair is adjusted by sliding the sucker cups (113) 10 within slot (112) of guide block so that according to size of books, the position of sucker is defined such that each book is gripped by one pair of sucker. After gripping, each pair of sucker (116) is separated linearly so that books are separated from their partition line. Said separated books are conveyed to back stopper assembly (3) where books are properly positioned and then 15 corner cutting assembly carry the corner cutting of books.
