    摘要： An optical scanning module has a metal base, a first circuit board mounted across one end of the metal base and a second circuit board mounted orthogonal to the first circuit board. The metal base supports a light emitter for producing a scanning beam and serves as a heat sink for the emitter. A flexible support attached to the metal base supports a mirror for oscillating motion. The module includes a drive mechanism, typically in the form of a permanent magnet and electromagnet, for producing reciprocal motion of the mirror. A detector included in the module senses light reflected from an indicia scanned by the beam. A flexible electrical cable connects the circuitry on the first and second circuit boards so that circuitry operates together to produce all signals necessary for operation of the scanner module and to process the electrical signals from the detector. Preferred embodiments include a flexible support consisting of a planar spring located between the mirror and one of the magnets. The components of the module are dimensioned so that the weight of the magnet balances that of the mirror. The invention also encompasses systems for scanning the beam simultaneously in two orthogonal directions at two different frequencies. This bi-directional scanning can produce a raster scan pattern for reading two-dimensional bar codes, or this scanning can produce a moving zig-zag pattern for reading truncated bar codes.

    摘要： A unitary body of optical material and associated methods for reading indicia such as bar codes is provided. The unitary body can focus light from a light source into a beam, redirect light reflected from a target to a photodetector, and provide mechanical support for a light source, printed circuit board, or other indicia reader components. In comparison to conventional apparatus, the unitary body requires a reduced number of components and is therefore easier and less expensive to manufacture and assemble. The unitary design increases reliability and performance consistency while decreasing sensitivity to thermal and mechanical loading. Moreover, the unitary body reduces the overall tolerance budget of a reader and therefore facilitates mass production of optical apparatus and readers. The unitary body and associated methods may be implemented in a compact reader with the aforementioned advantages in the form of a pen, or can be integrated into an antenna of a wireless device, such as a cell phone or a PDA.

    摘要： In an optical scanning module, for reading indicia with portions of differing light reflectivity, having a light emitter assembly for emitting a light beam towards the indicia, and a detector for receiving light reflected back from the indicia and producing an electrical signal corresponding to the differing light reflectivity of the indicia, an optical scan module component is provided which includes two circuits on respective circuit boards which are angularly mounted, and preferably orthogonally mounted, to each other. The two circuit boards are electrically connected to each other so as to operate together to produce signals to drive the emitter assembly and to process the electrical signal produced by the detector. The first and second circuit boards each form at least a portion of a peripheral side of the scanning module and thus, defining a wall of a chamber having the light emitter assembly disposed therein, and wherein the scanning light beam moves relative to the first and the second circuit boards.
