ABSTRACT:
An automatic document handler includes a compact document handling system capable of automatically feeding cut sheet documents and computer form documents to a pair of scanner arrays arranged on opposite sides of a curvilinear document transport path. The document handling system includes a constant velocity transport comprising at least a roller pair located along a curved portion of the curvilinear transport path to eliminate interference between a sliding scanner array and document feed rollers. The document handler scans originals without transporting them over the platen and the platen cover serves as an input tray for computer form original documents.
