ABSTRACT:
The collating device sucks up the topmost sheet of the paper stack on the paper table by the suction head and feeds forward the sheet one after another. The paper table is being given an upward force by a spring. This paper table moves up to the position where the topmost sheet of the paper stack on the paper table contacts with a stopper. This stopper moves up during the period when the suction head feeds forward the topmost sheet. At this time, an electromagnetic brake is set at the on-state and fixes the position of the paper table. The suction head, stopper, electromagnetic brake and the like rotate at the predetermined timing based on the rotation of cams. Thus, according to this invention it is possible not only to save the cost of the device but also to operate the device at high speed.
