ABSTRACT:
A bar code scanner has an increased number of outgoing beams and number of directions of the beams effective for reading of a bar code. The bar code scanner includes a light source for generating a laser beam, a rotary scanning mechanism for receiving the laser beam from the light source and emerging a scanning beam, and a separation mirror for reflecting the scanning beam from the rotary scanning mechanism to separate the scanning beam into a plurality of scanning beams. The bar code scanner further includes a scanning pattern generation mirror mechanism for reflecting the plurality of scanning beams reflected on the separation mirror toward a reading window to generate a scanning pattern composed of the plurality of scanning beams.
