ABSTRACT:
In a paper sheet stacking apparatus according to the present invention, continuously fed paper sheets are received by rotating blade wheels, and are then dropped from the blade wheels at a predetermined position by means of a stationary stop. A separator capable of rotating coaxially with the blade wheels is stopped at the paper sheet dropping position to bear thereon the first of many sheaves of paper sheets to be allotted out of the dropped paper sheets. The paper sheets on the separator is temporarily transferred to an auxiliary stacking unit, and the separator is removed from the blade wheels. Then, the separator is rotated without touching the paper sheets and stopped at a position beside a stand-by position where it waits for the first paper sheet out of the next sheaf of paper sheets to be inserted into the blade wheels. Thereafter, the separator is moved further toward the blade wheels and stopped at the stand-by position. Meanwhile, the paper sheets on the auxiliary stacking unit are transferred to a main stacking unit so that the main stacking unit can receive and bear thereon the paper sheets to be dropped thereafter. Thus, regular sheaves of paper sheets each consisting of a predetermined number of sheets may successively be formed on the main stacking unit without interrupting the feed of the paper sheets to the blade wheels.
