Transportation mechanism, method for controlling transportation mechanism and transporting method

The present invention relates to a conveying mechanism capable of reducing shakes more effectively and conveying paper smoothly and steadily, without damaging the paper, a control method of the conveying mechanism and a conveying process. A first blast engine (13) and a second blast engine (14) for blowing air are set respectively fore and after handing over and taking over of paper (2) from thepaper discharging roller (12) to the clip (112). The first blast engine (13) blows air, before the handing over and taking over of paper (2) from the paper discharging roller (12) to the clip (112), to prevent paper (2) from deviating from the paper discharging roller (12). On the other hand, the second blast engine (14) blows air, after the handing over and taking over of paper (2) from the paperdischarging roller (12) to the clip (112), to prevent paper (2) from contacting with the clip (112).
