ABSTRACT:
An multi directional laser scanner apparatus has a frame along with a plurality of lasers removably mounted in circular fashion to the frame for producing a plurality of light beams. A multi-faceted rotating mirror assembly is rotatably mounted to the frame and rotated by an electric motor and is aligned with a plurality of laser output beams. A plurality of fixed mirrors are attached in pairs to the frame and positioned for reflecting the light energy of the laser beam being reflected by the rotatable mirror assembly in a pattern onto a coded surface and positioned for receiving reflected beams from the coded surface and than directing the reflected beams in a reverse path onto the rotating mirror assembly and back towards each laser. A mirror mounted adjacent the output of each laser reflects each returning laser beam onto a photocell mounted to the frame for receiving the reflected signals from the coded surface and the signals are processed to read the coded signals. An alternate embodiment replaces two of the fixed array mirrors with a galvanometer and mirror assembly which oscillates a mirror affixed to each galvanometer to produce a second set of output scan lines over the primary laser output scan lines onto a bar code to reduce the chance that a small bar code will not be read by the primary scanner.
