Abstract
A hand-operated document processor has 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/cylinder mechanism includes a spring providing the force necessary to drive the moving MICR subsystem, and includes a dashpot composed of a piston and cylinder arranged such that the spring moves the MICR subsystem across the document being processed and drives the piston in the cylinder, thereby damping the motion of the MICR subsystem.
