ABSTRACT:
A paper holding bin including a movable bottom tray for holding a stack of print receiving material such as paper. The bin is part of a machine using sheets of paper such as a copier or printer. The front edge of the paper stack is positioned at the front edge of the tray and against the front wall of the bin. A biasing spring is used to move the tray upwardly along the front wall of the bin until the top sheet of the stack bears against a paper feed roll. As sheets are fed from the stack, the spring continues to bias the tray upwardly so as to keep the top sheet of the stack against the feed roll. Cams of circular arc are provided at the rear edge of the tray, extending upwardly therefrom, to bear against the rear wall of the bin. In that manner a rolling pivot point is provided so that the front edge of the tray remains virtually equidistant from the front edge of the bin, regardless of whether the stack is large or small.
