Patent ID: 8056810

Claim:
A bar code scanner, comprising: multiple laser sources for generating multiple laser beams, the multiple laser sources being positioned and oriented such that the multiple laser beams generate reflected laser beams, originating as reflections of the multiple laser beams from the facets of a rotating spinner, each of the multiple laser beams being simultaneously reflected from the same facet of the rotating spinner as the facet passes in the path of the multiple laser beams, the reflected laser beams emerging from the scanner as scan beams and tracing out scan lines as the spinner rotates, the scan beams tracing out scan lines in a scan zone, the multiple laser sources being positioned and oriented such that the angles of reflection of the multiple laser beams from the facets of the rotating spinner result in divergence of the scan lines produced by the reflected scan beams; a plurality of detectors, each of the detectors being positioned so as to receive reflected light rays representing reflections of a laser beam originating from one of the laser sources; a collector for collecting and focusing reflected light rays representing reflections of the multiple scan beams from an object within the scan zone, the collector focusing the reflected light rays representing reflections of the multiple scan beams onto the detectors such that reflected light rays representing a reflection of each scan beam are directed to a detector positioned to receive light rays representing a reflection of that scan beam wherein the multiple laser sources comprise at least first and second laser sources for generating first and second laser beams and the first and second laser sources are horizontally offset from one another with respect to the rotating spinner; pattern mirrors and a scan window, and wherein a pattern mirror directs the first and second laser beams from the rotating spinner out the scan window to the scan zone; and wherein the first and second laser sources are horizontally oriented from one another in opposite directions with respect to the spinner and the collector comprises a reflective ellipse with holes for passage of the first and second laser beams from the first and second laser to the rotating spinner.
