Abstract
A high capacity copy sheet supplying system for reproduction apparatus, in which a large and heavy stack of copy sheets may be much more easily and accurately loaded therein, by a sheet supplying container insertable into the sheet supply input. This container has sheet stack confining side walls, a bottom wall with plural spaced apertures, and a false bottom tray insert loosely overlying that bottom wall on which the stack of copy sheets is supported. Plural lift rods are operatively connecting with an elevator system to provide movement of the lift rods up through the apertures in the bottom wall of the sheet supplying container, to engage and lift the false bottom tray and the large and heavy stack of copy sheets supported thereon by engagement of the ends of the lift rods, so as to lift up the large stack of copy sheets from within the sheet supplying container into engagement with a fixed position sheet feeder, and then to automatically maintain feeding of sheets from the top of the stack by maintaining with the elevator system the level of the top of the stack until the sheets are depleted by the sheet feeder. The same container can be used for an output stacker. It also may …
