Hand-operated document reader/imager with speed limiting device providing document retention

摘要

A hand-operated document processor includes a base for receiving a document containing magnetic ink character data to be read and recognized. A manually operated moving magnetic ink character recognition (MICR) subsystem includes a MICR read head and is attached to the base. Movement of the subsystem causes the MICR read head to pass over the magnetic ink character data on the document. MICR reading and recognition logic receives the signal from the MICR read head. A spring drives the moving MICR subsystem across the document being processed. A vacuum solenoid creates a vacuum. The vacuum solenoid is driven by the spring and is connected to the base. The created vacuum acts as a brake to control the speed of the moving MICR subsystem as the moving MICR subsystem is driven by the spring.
