Abstract
Disclosed is a document handler and feeder device for performing high speed separating and transporting of documents, such as business forms. The document handling unit is equipped with friction type feed rollers and a lipped contour plate over which documents must pass. The feed rollers contact and transport a foremost document from a gravity-feed document hopper. High speed tracking belts are mounted over grooves or tracks, which extend along a track plate and through the lip of the contour plate. The feed rolls force the leading edge of the foremost document into the lip where the document engages the bottom side of the belts so that it is nipped between the belts and the contour plate causing the document to move into the tracking grooves. In order to provide ready access to the tracking plate area, the entire tracking belt drive assembly is pivotable upwards about a pivot pin located adjacent the feed roller shaft.
