ABSTRACT:
A paper supply tray having a constant force spring operated elevator platform for holding a stack of print receiving material is provided for use in a reproduction apparatus. The constant force spring in conjunction with a sheave and cable system moves the elevator platform such that the top sheet of the stack of sheets contained on the elevator platform is positioned for serially feeding by a sheet feeding mechanism. As sheets are fed from the stack, the constant force spring moves the elevator platform over a vertically guided path to maintain the top sheet of the stack in position for feeding by the feeding mechanism.
