  • Optical scanning carriage
    Patent number: 4603963
    Abstract: An optical scanning carriage is arranged to be moved along guide rails placed in a plane beneath, and parallel to an object plane. Magnets are incorporated into the carriage base to provide an attractive force between the carriage and the guide rails. This attractive force is designed to balance and neutralize forces associated with high scan rates which would tend to lift the carriage from its sliding contact along the guide rails.
