Abstract: A scan pattern generator for use in a bar code reader which uses a single drive (one coil and one magnet) to produce movement of a reflective surface so as to produce an oscillating movement of the surface in two directions, thereby forming a raster-type scanning pattern when a light beam is reflected off the surface.
