ABSTRACT:
An optical scanner includes a housing having first and second obliquely adjoining windows. Disposed in the housing is a laser for projecting a laser beam against a rotatable spinner having a plurality of mirrored facets for sequentially reflecting the laser beam to effect a scan beam. A plurality of pattern mirrors are optically aligned with the spinner for reflecting the scan beam through the first and second windows to effect a plurality of individual scan lines arranged in first and second patterns corresponding with the first and second windows. The pattern mirrors include a triad set of mirrors optically aligned in series between the spinner and the first window for scanning the first scan pattern to a back edge of the first window for scanning at least the back side of a multisided item.
