Abstract
A sheet stacking apparatus for receiving sheets from a printing or copying machine includes guide structure for directing output sheets onto an elevator platform and a selectively rotatable shaft having paddle arms disposed at a 108.degree. interval. The shaft rotation is controlled so that the arms guide a sheet during stacker input and then rotates 360.degree. to positively clear the sheet trail edge from the stacker input path.
