ABSTRACT:
In a combination document feed system and document removal assembly associated with the document feed system for removing documents one at a time from a stack of documents disposed in the document feed system and feeding each document into a document transport system: comprising a document removal assembly for providing a substantially elongated contact surface between the document removal assembly and a lead document in the stack of documents, the contact surface adapted to alternately contact the lead document and advance the lead document from the document feed system to the document transport system. The document feed system includes belts for advancing the stack of documents toward a document removal assembly, including a back plate adapted to provide a compressive force to the rear of the stack of documents. The back plate is driven at the same speed of travel as the belts advance the stack of documents, and applies a progressively decreasing compressive force to the stack of documents as the stack of documents decreases in size.
