ABSTRACT:
Documents are inserted into a bin beneath a document stack already in the bin. An air bearing holds the document stack above the floor of the bin. A lifting mechanism lifts the stack along one edge so that a document is driven between the last sheet in the stack and the floor of the bin. A selectively activated drive means positioned on the floor of the bin advances the document into proper registration into the bin. Documents can be fed from the top of the stack simultaneously with the bottom stacking operation.
