Further, when the paper sheets are held by the stacking means and the transport speed by the stacking means is reduced, the timing for holding the paper sheets by the installation positions of the stacking means and the transport means and the operation speed control is determined by the transport means. Since the setting is made so that there is no conveyance force to the paper sheets, it is possible to prevent buckling and jamming due to excessive feeding of the paper sheets to the stacking means when the paper sheets are transferred to the stacking means. it can. Also, by setting the gripping force of the paper sheet by the conveying means to be small so that the paper sheet can slide between the paper sheet and the conveying means, the paper sheet is held by the accumulating means. Since the sheet can be relatively slid between the sheet and the conveying means on the side of the conveying means at the same time, the same effect as described above is obtained.

Further, in the paper sheet handling apparatus provided with the separating means, the carrying means and the stacking means for carrying out stacking after separating and carrying the paper sheets one by one, the paper sheet transport state detecting means is , The timing of conveying the paper sheets conveyed to the stacking means is detected. The conveyance resistance imparting means imparts a conveyance resistance force to the paper sheets conveyed to the accumulating means such that the paper sheets are decelerated and are aligned and stored when accumulated in the accumulating means.

Further, the space forming means applies a conveyance resistance force to the paper sheets that have entered the stacking means, presses the already stacked paper sheets in the stacking direction, and subsequently enters the paper sheet. A space is provided for guiding the leaves, and a trailing path for the succeeding paper sheets to escape from the paper sheet entrance path before the succeeding paper sheet enters the space.
