In a bookmaking apparatus, a sheet bundle applied with adhesive in the apparatus when conveyance trouble, i.e., a cover sheet paper jam, occurs, is not left in the apparatus. Furthermore, the apparatus does not leave a cover sheet in the apparatus to be soiled if adhesive from a heated sheet bundle drops. The apparatus includes a sheet holding device for holding a sheet bundle at a predetermined adhesive application position, an adhesive application device for applying adhesive to the sheet bundle at the adhesive application position, and a cover sheet conveyance device for conveying the cover sheet to a binding position arranged at a downstream side of the adhesive application position.

In bookmaking, a sheet bundle is held in a substantially vertical posture. At first an adhesive is applied to a bottom edge of the sheet bundle in a condition that the bottom edge of the sheet bundle and an adhesive application member are pressed together with a first contact pressure to apply the adhesive between the sheets. Then, the adhesive is applied to the bottom edge in a condition that the bottom edge of the sheet bundle and adhesive application member are pressed together with a second contact pressure weaker than the first contact pressure, or are in a non-contact situation.

A sheet bundle conveying device includes a tray device on which sheets are placed and held in a bundle, a sheet bundle conveying path along which a sheet bundle from the tray device is guided to a predetermined processing position, a grip transferring device located on the sheet bundle conveying path for gripping and transferring the sheet bundle from the tray device to a processing position, and a grip controlling device for controlling the grip transferring device. When an apparatus error occurs, the grip transferring device moves the conveyed sheet bundle backward to the collection stage. A grip on the sheet bundle is released on the collection stage after the sheet bundle is returned.

Bookbinding apparatus facilitating, in the event it is halted during operation, the removal of any sheave left remaining inside, to eliminate the risk of sheets scattering. A sheet bundler/stacker bundles printed sheets into sheaves. Along a binding process path are provided a sheave transporter for transporting the sheaves and, at the downstream end of the bundler/stacker, an adhesive applicator in an adhesive-application position and a front-cover binder in a front-cover binding position. A sheave exiting-conveyor conveys sheaves from the front-cover binder into a storage stacker. A sheet-position recognizer detects/monitors the position of a sheave in the binding process path. If the bookbinding operations are interrupted, the position of any sheave left in the binding process path is determined by the sheet-position recognizer, and when the apparatus is restarted the order of the binding processes is altered depending on the position in which the sheave is left behind.

A sheet discharge apparatus includes a discharge device for discharging sheets, a storage device for receiving the sheets discharged by the discharge device, alignment reference members for aligning at least one side of the sheets discharged to the storage device, rotating bodies (belt unit) that contact the sheets at a predetermined position on the storage device to move the sheets to the alignment reference members, a support device for supporting the rotating bodies to move freely between an activating position that contacts the sheets at the predetermined position and a retracted position away from the sheets at the predetermined position, and a control device for controlling the support device to position the rotating bodies at the retracted position when the sheets reach the predetermined position before a trailing edge of the sheets in a discharge direction is discharged to the storage device by the discharge device.

A configuration controls the height and the inclination of a stacking tray according to the number of sheets discharged and controls the height and the inclination of a stacking tray when discharging sheets and when discharging sheet bundles to improve alignment of discharged sheets and the transporting characteristics. When discharging a sheet bundle, a stacking tray is lowered and when it reaches its home position, the aforementioned stacking tray is stopped. When discharging a sheet, the system determines whether it is the first sheet of a plurality of sheets in a bundle. For the first sheet, a timer is set to a predetermined time from raising to stopping the aforementioned stacking tray (using a pulse count value) and the aforementioned stacking tray is raised. After the set time is up, the stacking tray is stopped at a preset position.

In binding a cover sheet together with a sheet bundle, ever-accurate spine-creasing irrespective of bundle thickness is made possible. A sheet stacker stacks sheets into bundles, an adhesive applicator applies adhesive to a spine part of the sheet bundles, and a cover-sheet binder binds cover sheets together with the spine parts. The cover-sheet binder is constituted from a left-and-right pair of spine-creasing press members arranged free to shift between standby and spine-creasing positions; a shifter that reciprocates the spine-creasing press members between the standby and spine-creasing positions; and a controller. The controller functions to vary, in accordance with sheet bundle thickness, any of: (1) the standby position of the press members; (2) the start time of an operation whereby the press members are shifted from the standby to the spine-creasing position; or (3) the traveling speed of the press members in shifting from the standby to the spine-creasing position.

Imaging-system bookbinding apparatus avoids cutting any folded sheets mixed into booklets it trims. Furnished with: an imaging unit; a sheet-folding unit that folds imaging-unit sheets; a stacking unit that stacks sheets from the sheet-folding or image-forming units; a cover-sheet binding unit that encases stacking-unit sheet bundles with, and binds them into, cover sheets; a trimming unit that trims true the bundle fore-edge; and a fold-position computing unit that determines where a sheet is pleated by the sheet-folding unit. The sheet-folding unit has a sheet conveyance path along which folded sheets are transported elsewhere than the stacking unit, while the fold-position computing unit in a first control mode transports to the stacking unit sheets folded over by the sheet-folding unit, and in a second control mode transports them from the sheet conveyance path elsewhere than the stacking unit.
