  • Patent number: 8931774
    Abstract: A sheet processing apparatus which is capable of completing a bound document containing appropriately Z-folded sheets when performing folding together with edge cutting and binding. The sheet processing apparatus controls a Z-folding process, a cutting process, and a binding process for a sheet. A first folding position from a free end of the sheet coincides with a position corresponding to half a width of the sheet excluding a cut width of the sheet a binding margin, when the Z-folding process, the cutting process, and the binding process are executed.

  • Patent number: 8915490
    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.

    Abstract: Sheets center-folded by a center-folder are placed on a main saddle. A buffer saddle is provided separately from the main saddle, on an opposite side of the center-folder across the main saddle. The pile of sheets saddle-stitched on the main saddle is placed on the buffer saddle. When viewed from above, the buffer saddle is movable in a direction separating from the main saddle that is a reverse direction to the center-folder, and in a direction orthogonal to the direction separating from the main saddle. A sheet processing device is arranged in the orthogonal direction where the buffer saddle is movable.

  • Patent number: 8844919
    Abstract: A post-processing apparatus includes a folding section configured to nip a sheet using a plurality of rollers to form a fold line for saddle stitching and a control section to control the nipping amount in the folding section. When carrying out square back processing to flatten the spine folded portion of a sheet bundle where a fold line for saddle stitching is formed, the post-processing apparatus allows the nipping amount in the folding section to be smaller than that in the case where the square back processing is not carried out.

  • Patent number: 8794615
    Abstract: A sheet post-processing apparatus capable of stably stopping a clamping member at a predetermined target position (holding position), of performing post-processing regardless of thickness of a sheet bundle. A holding member is used for holding a sheet bundle. A moving unit moves the holding member between a predetermined reference position and a predetermined holding position at which the holding member holds the sheet bundle. A sheet post-processing unit performs post-processing on the sheet bundle held by the holding member. A control unit configured to, when the holding member is moved from the reference position and is stopped at the holding position by the moving unit, decelerate a moving speed of the moving unit, before performing a stopping process of the moving unit, such that a deceleration rate of the moving speed is smaller as a thickness of the sheet bundle is larger.

  • Patent number: 8740211
    Abstract: A sheet post-processing apparatus which is capable of preventing a stapling position and a folding position from being out of alignment when a stapling process is carried out. A sheet bundle, which is stacked in a housing guide, is stapled by a stapler using a staple at the stapling position. The sheet bundle is folded at a position of the staple after the stapling. After the stapling, the sheet bundle is moved from the stapling position to the folding position. During the movement, the staple is detected using a staple sensor disposed at a predetermined location between the stapling position and the folding position. Based on a moving distance of the sheet bundle before the staple is detected after the stapling process, a position of the sheet bundle with respect to the stapler for stapling on a subsequent sheet bundle is corrected.
