  • Scanner and method for sweeping a beam across a target
    Patent number: 7193758
    Abstract: A scanner such as a bar-code scanner includes a scan-beam generator, a beam reflector having a first magnet, and a beam-sweep mechanism having a second magnet. The beam-sweep mechanism causes the reflector to sweep the scan beam across a target such as a bar-code symbol by exerting a force on the first magnet with the second magnet. 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.
