ABSTRACT:
A portable, stand-alone desk-top, optical scanning apparatus includes a first housing member positioned on the top surface of a checkout counter in which is mounted on the floor portion of the housing member, a light emitting element for projecting scanning light beams within the housing member, and a floor-mounted multifaceted rotating mirror for directing the light beams at a plurality of floor-mounted twisted mirror members which reflect the light beams through an aperture in the cover portion of the housing member, said light beams forming a pattern for scanning a bar code label on a merchandise item positioned on top of the housing adjacent the aperture. Light reflected from the label is directed back through the housing member towards a photodetector which generates electrical signals for processing by an electrical circuit located within the housing. A second housing member remotely positioned from said first housing member contains a power supply for operating the scanning apparatus and a laser for generating the light beams. A cable transmits the electrical power and the light beams to the light emitting element from the second housing member.
