APPARATUS FOR STACKING SHEETS

摘要

Stacking apparatus for stacking sheets being fed thereto at high speed along a feed path. A base is positioned a spaced distance below the feed path of the documents. A stacker plate is arranged above the base with its upstream end positioned above the feed path and the downstream end adapted to rest upon the base at a spaced distance from the end of the base lying beneath the stacker plate. The stacker plate is curved to include an upstream concave portion and a downstream convex portion confronting the documents to guide the leading edge of the documents along the bottom surface of the plate downwardly towards the downstream end of the plate to be stacked on the base beneath the downstream end of the plate. Means are provided for swingably mounting the upstream end of the plate to enable the downstream end to move upwardly as the height of the stack increases. The stacker plate further includes an end wall at the downstream end for limiting movement of the sheets in the feed direction. Rebound prevention means are provided on the stacker plate for preventing sheets striking the end wall from rebounding therefrom.
