    摘要： The present invention relates to a servo controlled stitching apparatus that comprises a servo controlled wire pulling means (4) for pulling the required length of wire for stitching bunch of paper sheets. Said pulling means (4) comprises pulling roller (11) having wire retaining groove (11a) for guiding wire extending from the spool (2) towards the stitching head (1). It also comprises pressure roller (13) that rotates against pulling roller (11) for pulling the wire (16) from the spool (2). The length of wire to be pulled is predefined in the controller means which is communicated with the servo motor (7) that rotates said rollers (11, 13) until the predetermined length of wire is pulled. The stitching head (1) utilize the wire (16) of pulled length without rotating the spool itself to avoid pulling load and to apply even stapling on the bunch of paper sheets.

    摘要： A sheet processing apparatus in which a sheet bundle including a plurality of sheets discharged onto an intermediate processing tray (107) is received in a receiving portion of a stapler (110) and bound with use of a staple, and a sheet bundle including a plurality of sheets discharged onto the intermediate processing tray is received in a receiving portion of a staple-less binding unit (102) having a gap in the thickness direction of the sheets smaller than that of the receiving portion of the stapler and bound without using a staple, wherein when the stapler performs the binding process, the staple-less binding unit is arranged in a position shifted in a width direction orthogonal to a sheet discharge direction from a region on the intermediate processing tray, through which the sheets discharged by a sheet discharging portion pass.
