Abstract

This stacking mechanism receives and stacks copy paper in copier apparatus The backing plate 10 is attached to flexible endless belt 12 which is freely slideable on ball bearing rollers 14,16. The flexible belt 12 moves with the backing plate 10 and provides edge support for the accumulated documents. Spring 18 acts through arms 20,22 and linking mechanisms 26 to exert force against the backing plate 10. This force is opposed and in proportion to the weight of documents on the plate, so that the increment of document weight required to overcome the equilibrium of the system and move the supporting plate and belt assembly is a constant associated with the weight of a single document, rather than the weight of the accumulated documents.
