    • PROBLEM TO BE SOLVED: To efficiently correct a curl of a recording paper, to be sucked and conveyed by a conveying belt.SOLUTION: Suction fans 44a-44f corresponding to each of right and left, and center regions in a main scanning direction are driven by drive patterns for a thin paper when a print job which uses thin recording paper S for printing is generated. Suction force generated in both right and left regions on a suction surface 41a of a belt platen is increased than suction force generated in the center region. The recording paper S is lifted from a center of the belt platen in the main scanning direction in several portions between individual paper pressing rollers 54, 54 between both right and left ends in the main scanning direction, to prevent a wrinkle from being formed on the recording paper S.
    • 要解决的问题:有效地校正由输送带吸引和传送的记录纸的卷曲。解决方案:驱动对应于主扫描方向上的左右两个中心区域的吸入风扇44a-44f 当使用使用用于打印的薄记录纸S的打印作业时,通过用于薄纸的驱动器图案。 在带压板的吸附面41a上产生的左右两区域的吸力比在中心区域产生的吸力增加。 在主扫描方向上的两个左右两端的各个压纸滚筒54,54之间,记录纸S在主扫描方向上从主扫描方向的中心部分提升,以防止在主扫描方向上形成褶皱 录音纸S.

    • PROBLEM TO BE SOLVED: To provide a sucking device for sucking air from the upper end region at the side of the sheet pile of the paper discharging device of a sheet-fed printing press, with which fully efficient suction of air is realized even under the condition that the distance between the side end part of the sheet pile and an air catching device provided at its side is comparatively larger.
      SOLUTION: This sucking device for the paper discharging device of the sheet-fed printing press sucks the air from the upper end region at its side and has the air catching device 3. The air catching device 3 as one for catching the air faces to the upper end region at its side and has a catching opening part 3a extending towards the longitudinal direction of the sheet pile BS. In the catching opening part 3a, an auxiliary conveying device 2 for catching the air sent from the upper end region of the sheet pile BS and the exhausting the caught air towards the catching opening part 3a, is provided in an intermediate region between the side region of the sheet pile BS and the catching opening part 3a.
