ABSTRACT:
A barcode scanner includes a laser for emitting a laser beam toward a rotary spinner. The spinner includes a plurality of mirror facets for reflecting the beam in turn therefrom towards a plurality of pattern mirrors. The mirrors in turn reflect the beam to form corresponding scan lines emitted through a window having a width along a first axis of the scanner, and a height along a second axis of the scanner perpendicular thereto. The pattern mirrors are collectively positioned around the spinner to effect a pattern of scan lines on the window extending substantially completely across the height thereof for correspondingly providing full height coverage scanning of a barcode traversing the window along the first axis.
