Each of the sheets is conveyed by a horizontal conveyance unit in a state of being overlapped with a next sheet from above. Each of the sheets is conveyed out of the horizontal conveyance unit in a state of being folded along a fold line with the fold line oriented upward, the fold line extending in a conveyance direction of the horizontal conveyance unit. An oblique conveyance unit receives the sheet from the horizontal conveyance unit and successively conveys the sheets in an oblique downward direction. A sensor is arranged to detect passage of the sheets at a position where steps pass. Each of the steps is formed by two sheets adjacent to each other diverted to the oblique downward direction by the oblique conveyance unit.

Sheet detection device and sheet detection method

A pair of conveyance rollers are arranged for signatures. The signatures is conveyed through the pair of conveyance rollers to a stacking unit while being sandwiched from both sides thereof between the pair of conveyance rollers. In response to passage of a signature for a sheet stack through the pair of the conveyance rollers, the conveyance rollers is switched from conveyance rotation to intermittent rotation to cause the pair of the conveyance rollers to keep the signatures for a next sheet stack from being conveyed to the stacking unit. In response to the stacking unit becoming ready to receive the signatures for the next sheet stack, the conveyance rollers is switched from the intermitted rotation or the stop to the continuous rotation to cause the pair of the conveyance rollers to convey to the signatures to the stacking unit.

Stacking device and method for sorting

The trimmer includes: a pusherthat pushes the bound materiala pusher moving device that moves the pusher; a positioning partthat positions the bound material pushed by the pusher; an allowable position memory that memorizes an allowable position range relevant to the pusher; an allowable reaction force memory that memorizes an allowable reaction force range relevant to the pusher; and a determiner that determines whether a length of the bound material is normal or abnormal. The determiner determines that: the length L of the bound material is normal; or the length L of the bound material is abnormal.

Trimmer

The creaserincludes a project partfor forming the creaseon the sheetand a receive partfor receiving the project part. The project partis moved between a crease position and a standby potion, the project partbeing at the crease position so as to form the creaseon the sheet, the project partbeing away from the sheetat the standby position so as not to form the creaseon the sheet. The input deviceincludes a selectorfor selecting the sheetto be creased by the creaserfrom among the sheetsfed from the conveyer, the input devicesending the information of the selection to the controller
