Abstract
Abstract A scanner with multiple modes of operation producing two or more distinct scan patterns, with each scan pattern optimized for different modes of operation with a manually actuated switching mechanism whereby the operator may readily select a desired scan pattern. The switching mechanism may operate by mechanically moving one set of scan pattern generating optics out of the optical path of the scanner and/or moving another set of scan pattern generating optics into the optical path. Alternatively, the different sets of scan pattern generating optics may remain stationary while the optical path of the scanner is moved. In either case the operator may choose from among two or more distinct scan patterns the scan pattern most appropriate to the scanning application at hand.
