Abstract

In an uphill output sheet stacking system, paper 1 is passed into the nip defined by rollers 3 and 4 and passed out onto sheet stack 5. Stack 5 is generally in paper tray 6, and particularly rests on flat linear spring 7. As the number of sheets in tray 6 increases, the weight on spring 7 increases causing compression of the spring 7, thus lowering the stack 5 such that each newly arriving sheet will be placed on the top of stack 5 which stays approximately at the same height.
