ABSTRACT:
Apparatus for receiving and stacking a large number of sheets such as electrophotographic copies in which the height of a support to which sheets are successively delivered is adjusted in response to a photodetector arranged to sense the height of the stack of sheets on the support. The sheet support is raised and lowered by rotating a lead screw engaging a follower carried by the support and is limited in its excursion by stops on the follower which circumferentially intercept stops carried by the lead screw to prevent further rotation of the screw.
