ABSTRACT:
An optical scanning pattern generator device (10) is provided to include a laser beam generator (14) for generating a beam (16) which is caused to trace a scan pattern (76) within a scan zone (24) by a scattering system (20). The unique scattering system (20) includes a rotating mirror (44) for directing the beam (16) radially outward in a circle within a rotation plane (42). A rotating prism ring (50), rotating at a different rate than the rotating mirror (44) refracts the beam from the rotation plane (42), the amount of refraction being dependent on the particular prism element (52) within the ring (50) which is intersected by the beam (16). The refracted beam then is reflected toward the scan zone (24) by one of a series of fixed mirrors (58) which are circumferentially arranged about the prism ring (50). The beam (16) may be reflected off of a scan object (26) and collected in collection apparatus (28). The primary industrial applicability of the invention is in an economical bar code reader device particularly adapted for retail usage.
