  • Retractable document handling mechanism for a document processing system
    Patent number: 7658381
    Abstract: A document processing system includes a feeder stage, a transport stage, and a retractable document handling mechanism cooperating with a portion of the document track. The mechanism includes an assertable member arranged with respect to the document track such that assertion of the member causes retraction of the opposed track walls in the cooperating portion of the document track by retracting a movable base member from a fixed base member. This provides access to the document track, and the retraction is sufficient to provide a track opening sufficient to allow the operator to relieve document jams.
