Abstract

A scanner such as a bar-code scanner includes a scan-beam generator (3044), a beam reflector (3040) having a first magnet (3048), and a beam-sweep mechanism (3042) having a second magnet (3052). The beam-sweep mechanism (3042) causes the reflector (3040) to sweep the scan beam across a target such as a bar-code symbol by exerting a force on the first magnet (3048) with the second magnet (3052). In one example, attraction between the magnets holds the reflector steady in a non-sweep position. Conversely, in a sweep position, repulsion between the magnets causes the reflector to oscillate and sweep the scan beam across a target such as a bar-code symbol. Because it does not include a motor for rotating a beam-sweep mirror, the scanner is often smaller and uses less electrical energy than motorized bar-code scanners.
