Abstract
The upper end of a movable plate for guiding paper sheets is fitted to a shaft on which the plate swings, and is suspended in a slit provided in a stacking box. The movable guide plate and a supporting plate are in a positional relationship in which the angle .theta. formed by them is at a certain prescribed degree, and even if relatively heavy sheets are deposited and hit against the movable guide plate, the plate will not be flipped up because it is supported by the supporting plate. When the stack of the sheets sufficiently increases in volume to reach the lower end of the movable guide plate, the upper end of the plate slides along the slit along with the further deposition of sheets, so that the angle .theta. formed by the movable guide plate and the supporting plate increase to deprive the latter from its supporting function, and the supporting plate, together with the movable guide plate, are pressed upward as the stack of sheets further increases in volume. For this reason, sheets can be stacked to the full capacity of the stacking box.
