Abstract

The printer paper feed mechanism disclosed herein operates to transfer a sheet of paper being printed from the printing platen to an output tray above the platen by means of a plurality of resiliently surfaced rolls carried on a shaft which is journaled in arcuate slots in end plates at either end of the platen roll. When the rollers are driven in one direction, the shaft walks along the arcuate slots toward a guide which is overlaid by a sheet of paper being fed from the platen. The rollers drive that piece of paper upwardly away from the platen and into the output tray.
