To neatly load paper sheet bundles on a paper discharge tray, and to prevent the paper sheet bundles from collapsing toward the upstream side of the conveying direction even when a large number of paper sheet bundles are loaded on the paper discharge tray.

A paper sheet bundle loading device includes a paper discharge tray 11 for loading paper sheet bundles P, a conveying means 12 for successively conveying the paper sheet bundles P substantially in the horizontal direction, and stacking them in a tile-stacking manner, a stopper 13 for stopping the movement of the paper sheet bundles P, and a holding means 14 that can prevent the paper sheet bundles P stacked in a tile-stacking manner from being abutted on the stopper 13, preventing the paper sheet bundles P conveyed successively from being in an upright condition, and prevent the paper sheet bundles from being collapsed upwardly in the paper sheet bundle conveying direction. A conveying area in which the paper sheet bundles P are conveyed by the conveying means 12, and a non-conveying area in which any paper sheet bundle P is not conveyed by the conveying means are successively provided in the paper discharge tray 11 from the upstream side in the paper sheet bundle conveying direction. A holding means 14 is provided on the upstream side of the paper sheet bundle conveying direction from a boundary B between the conveying area and the non-conveying area.
