ABSTRACT:
A sheet registering device for registering sheets without any time loss and any fold or breakage of the sheets. A paddler is equipped with two elastic blades, for example, as mounted on a pivotal shaft directed at a right angle with respect to a transporting direction of the sheets, and the adjoining elastic blades are set at an angle of 180.degree. or more. The sheets, as supplied to a staple tray, are transported by the rotating paddler until their downstream ends come into contact with a stopper, and are registered in the transporting direction. At this time, the elastic blades are in contact with the sheet surface. When the transportation and the registration in the transporting direction are ended, the rotation of the paddler stops with its elastic blades being generally in parallel with the tray. After this, the sheets are registered in a (widthwise) direction perpendicular to the transporting direction by a tamper plate. At this time, the elastic blades are kept away from contact with the sheet surface so that no pressure is applied downward to the sheets to neither fold nor break the sheets. Moreover, the transportation and the registration can be effectively carried out not by shifting the paddler itself but merely by controlling the rotation of the same.
