A post-processing apparatus according to an embodiment includes an adhesive binding unit that binds a plurality of sheets into a bundle. A controller sets an allowable binding number X of sheets capable of being subject to binding at one time in the adhesive binding apparatus. The controller sets a predetermined remaining number N of sheets. The controller receives a number A of the sheets instructed to be bound in the adhesive binding unit. The controller calculates a remaining number n of sheets, where n=AX. The controller determines whether n>N or nN. The adhesive binding unit binds the A number of the sheets into a single bundle when it is determined that nN.

A sheet binding apparatus includes a stack portion on which sheets are stacked; a manual setting portion, different from the stack portion, to which sheets are manually set from an outside of the apparatus; a first binding portion binding sheets stacked on the stack portion and set on the manual setting portion, the first binding portion being movable to a first position where sheets on the stack portion are bound and to a second position, different from the first position where sheets set on the manual setting portion are bound; and a second binding portion binding sheets stacked on the stack portion, the second binding portion being different from the first binding portion. The first position is set, with respect to a moving direction of the first binding portion, between the second position and a third position where the second binding portion binds sheets stacked on the stack portion.

In accordance with one embodiment, a sheet binding apparatus comprises a pasting section and a control section. The pasting section is capable of selectively carrying out pasting processing on at least one of a plurality of different given pasting target areas on sheets to be pasted. The control section controls the execution of the pasting processing based on the pasting section so that pasting target areas of a first sheet and a second sheet other than the first sheet within a plurality of sheets to be subjected to binding processing are different.

A mismatch detection system comprising a book block assembly line, a plurality of book block sensors, a case cover assembly line, and an infeed sorter. The book block assembly line may be operable to output conforming book blocks and divert nonconforming book blocks. The plurality of book block sensors may be operable to detect a unique identifier (UID) of the nonconforming book blocks diverted by the book block assembly line. The case cover assembly line may be operable to output case covers. The infeed sorter may be operable to receive the conforming book blocks and the case covers, group one book block and once case cover into a pair, detect whether the conforming book block and case cover of the pair match, divert any of the case covers that do not match, and output a matching pair to a book binding device.

If it is determined that a sheet on which image data of the front cover is to be printed is the particular sheet, a printing apparatus prints on sheets the image data of the body in an order from an end of the body toward a head of the body, discharges the printed sheets without reversing, finally prints image data of the front cover on the particular sheet, and discharges the particular sheet without reversing by the reversing unit, or firstly prints a mirror image of the image data of the front cover on the particular sheet, discharges the particular sheet without reversing, next prints on sheets the image data of the body in an order from the head of the body toward the end of the body, reverses these printed sheets and discharges these printed sheet.

A post-processing apparatus comprises a first processing tray on which fed paper is placed; a paper binding section configured to bind a plurality of sheets of paper stacked on the first processing tray into one bundle; a second processing tray which a plurality of paper bundles bound on the first processing tray are sequentially conveyed to and placed on; a paper bundle gluing section configured to coat glue at a given position of the top surface of a first paper bundle placed on the second processing tray before a second paper bundle is placed on the first paper bundle; a pressing section configured to press and bind the first paper bundle with the second paper bundle between which glue is coated; and a control section configured to control the timing for conveying the second paper bundle onto the first paper bundle after the glue is coated.

A sheet processing apparatus for processing a sheet includes a setting portion to which a sheet bundle is set from an outside of the apparatus, a conveying route in which a sheet is conveyed, a stack portion on which sheets conveyed from the conveying route are stacked, the stack portion being arranged at a different position of the setting portion, a binding unit which binds a sheet bundle set in the setting portion and a sheet bundle stacked in the stack portion, and a punching portion which forms a punch hole on a sheet, which is conveyed in the conveying route. The setting portion is arranged as being overlapped to the punching portion in a direction of intersecting with a conveying direction of a sheet conveyed in the conveying route.

A binding device includes a sheet-bundle forming unit; a binding unit that executes a series of operation including inserting a wire into a sheet bundle and bending the wire; a power supply unit; a detector that detects a first timing for transitioning from bending operation to recovery operation; a first timekeeper that measures time from a start point of the series of operation to a first time point, which is an end of a scheduled first-timing detection period; a unit-of-processing manager; and a supply power controller. When the first time point is reached before detection of the first timing, the controller causes the power supply unit to adjust the electric power before the first timing is reached, such that the first timing is detected before the first time point in the series of operation for a second bundle belonging to the same unit of processing as a first bundle.
