Abstract

An apparatus for stacking bundles of sheets includes an elongate stacking table capable of movement upwardly and downwardly, the stacking table being lowered in accordance with an increase in stacking amount of the bundles of sheets. A single-side-openable type shutter member is located above the stacking table and is adapted to support the bundles of sheets arranged in a row, the shutter member being capable of opening only in the direction perpendicular to the direction of the bundles of sheets being arranged in a row, so that the bundles of sheets are simultaneously dropped onto the stacking table. A stationary ruler member is adapted to restrict only one side surface of the bundles of sheets at the openable side of the shutter member and prevent the bundles of sheets from movement following the opening action of the shutter member so that the bundles of sheets are dropped to a predetermined location. A reciprocally movable expulsion pusher adapted to push blocks of the bundles of sheets dropped onto and supported in a row in their horizontal posture by an upper surface of the stacking table simultaneously in the direction perpendicular to the direction of the blocks being arran…
