Abstract
A high capacity sheet stacking system for stacking substantial quantities of the sequential sheet output of a reproducing apparatus on a sheet stacking tray providing an inclined sheet stacking surface at a substantial angle from the horizontal for receiving and registering sheets against an upstanding stack edge registration or alignment surface. Here, this stack edge alignment surface is automatically varied in height above the stacking surface with the change in stack height in the tray, in coordination with vertical repositioning of the sheet input level to the tray with stack height, so that an elevator system is not required for the stacking tray, and a simple fixed position tray may be used, yet high sheet stacking capacity provided.
