Abstract
A bar code scanner includes a window and a rotary spinner mounted therebelow having a plurality of circumferentially adjoining mirrored facets for sweeping light along a scanned arc. A light source projects a scan beam on the spinner, and a plurality of pattern mirrors are optically aligned with the spinner along the scanned arc in a forward path for diverting the scan beam outwardly through the window to a bar code for effecting a scattered beam therefrom. A collection mirror is optically aligned with the spinner along the scanned arc for receiving the scattered beam in a return path from the pattern mirrors and spinner in turn. A detector is optically aligned with the collection mirror for receiving the scattered beam, and a decoder is provided for decoding the scattered beam.
