    摘要： An optical scanner module, for use in a bar code reader, has an electromagnetic coil across which is disposed a thin flexible strip. Mounted to the center of the strip is an optical element, such as a lightweight mirror, and a magnetic element, such as a permanent magnet. When an AC signal is applied to the electromagnetic coil, a varying magnetic field is produced which interacts with the fixed magnetic field of the magnet causing the magnet and mirror assembly to flex the flexible strip (e.g., in a twisting motion), thereby changing the spatial orientation of the mirror. By suitably driving the electromagnetic coil, the mirror can be made to oscillate, thereby converting a laser beam directed onto the mirror into a scanning laser beam. The entire module is compact, inexpensive to manufacture, and robust. Additional robustness may be provided by incorporating shock-absorber material between the flexible strip and the electromagnetic coil, and protecting the mirror by covering the front surface of the scanner module with a transparent shield.

    摘要： A bar code scanning system including an optical scanner for scanning a target symbol, such as a bar code, and generating a corresponding electrical signal. The scanner housing may be mounted to a single finger ring support, which can be cylindrical in shape. The scanner housing may include a scanner activation switch, which may be of the voice recognition type. A transmitter for transmitting the analog or digitized electrical signal, either by wire or RF signal, to a receiver on the user's person is also included in the scanner housing. A decoder is preferably included within the receiver housing. The receiver housing may also have a display for displaying decoded data and a keyboard for inputting entry data. Signal processing circuitry for digitizing the electrical signals generated by the scanner may be included either in the scanner or receiver housing. The receiver housing also may include an RF transmitter for transmitting the decoded data and any entry data to a separate computer unit. The receiver housing can be worn on the user's wrist or belt.

    摘要： A miniaturized electro-optical, retro-reflective scanning module. The module has a base, a first circuit board, and a second circuit board mounted substantially orthogonal to the first circuit board. The base supports a light emitter for producing a scanning beam and optical elements for directing and collecting light energy. The emitted beam reflects off a fold mirror onto a reflector mounted on a drive for oscillation. The oscillating reflector, in turn, redirects the beam onto an indicia being read. The reflected light is reflected off the oscillating reflector and directed to the collection mirror before reaching a detector. The detector included in the module senses light reflected from an indicia scanned by the beam. The reflector is driven by an electro-magnetiz driven system, including a flexure and an actuation arm.
