  • Patent number: 10017350
    Abstract: A sheet processing apparatus that is capable of properly performing fold line processing at a position depending on a sheet bundle. In a sheet processing apparatus, sheets sequentially received from an image forming apparatus are stacked on a bookbinding processing tray to form a sheet bundle. The sheet bundle is folded at the center thereof, and is conveyed to a processing position. A press unit moves along a fold line portion of the sheet bundle to thereby perform flattening processing for flattening the fold line portion by pressing the fold line portion from a direction orthogonal to a thickness direction. A first pressing strength set by a user using the image forming apparatus and the second pressing strength acquired information on the sheet bundle are compared with each other, and the processing position is determined based on a result of the comparison.

  • Patent number: 9771236
    Abstract: In a saddle-stitching apparatus, when a sheet is transported to a center-folding unit, a folding blade moves from a retrieved position to a nip position between a pair of folding rollers. A forward end of the folding blade comes into contact with a fold of the sheet, so that the sheet is folded along the fold. When the sheet is attached to the nip position between the folding rollers, the folding rollers start rotating and then, the folding blade inserts the center-folded sheet between the folding rollers. After the center-fold finishing is completed, the rotations of the folding rollers stop in timing at which the folding blade is pulled out of the nip position between the folding rollers. When pulling the folding blade out of the nip position between the folding rollers, the rotations of the folding rollers restart.

  • Patent number: 8596630
    Abstract: A sheet processing apparatus which is capable of stabilizing a stop position of the sheet bundle, to thereby enable creation of a high finish quality product, and is compact in size and can be manufactured at low costs. Conveyance belts convey the sheet bundle to a flattening position. A pressing roller flattens the folded spine of the sheet bundle by pressing the folded spine. Clampers hold the sheet bundle such that the sheet bundle is not moved when flattening is performed. A CPU starts to stop driving of the conveyance belts when the sheet bundle is conveyed to a predetermined location upstream of the flattening position in the conveying direction of the sheet bundle, and stops the sheet bundle at the flattening position by holding the sheet bundle with the clampers before the conveyance of the sheet bundle is stopped.

  • Patent number: 8596631
    Abstract: A sheet processing apparatus includes a sheet stacking unit, a binding unit, a folding unit, a conveyance unit, a press unit, a grasping unit, and a control unit. The binding unit performs binding processing on a sheet bundle stacked in the sheet stacking unit. The conveyance unit conveys a sheet bundle folded by the folding unit. The press unit presses a fold line portion of the conveyed sheet bundle from a direction perpendicular to a surface of a front page of the sheet bundle while moving along the fold line portion. The grasping unit is switched between a first state in which the grasping unit fixes the sheet bundle in position and a second state in which the grasping unit does not grasp the conveyed sheet bundle. The control unit shifts the grasping unit to the first state and causes the press unit to press the sheet bundle.

    Abstract: A post-processing apparatus includes a transport path, a loading part, a first folding member, a second folding member, a drive mechanism, a position detecting unit, a time information output part, a time monitoring part, and a rotational driving control part. The time monitoring part measures a moving time of the blade member from a first position between an initial position and a protrusion position to a second position, and determines whether the moving time has elapsed by a predetermined time. When the time monitoring part determines that the moving time has elapsed by the predetermined time, the rotational driving control part controls a rotary drive part so as to switch a rotational driving direction into a backward rotational direction.
