摘要： A bar code reader has an integrated scanning component module which is mountable on a printed circuit board. In one embodiment, the module may include the digitizer/decoder electronics, enabling the module to be used with a generic PCB. In some embodiments, the module includes a high speed optical scanning arrangement having an optical element which extends longitudinally of a flexible member, secured at one end. In other embodiments, the invention extends to a hand-held optical scanner having a scanning assembly, detector and data transmission coupling all mounted to a common printed circuit board, preferably located within a manually-graspable handle. In yet a further embodiment, an abuse-detector or accelerometer is provided for determining when the device is exposed to deceleration above a predetermined limit, and optionally for automatically shutting down applications programs and for providing a black-box-record of a short time frame before the device was exposed to an unexpected shock. Preferably, the reader is shock protected by a thermo-plastic elastomer housing section. An outgoing light beam is directed at a non-orthogonal angle relative to the PCB.

摘要： An optical scan module, for example for an optical scanner, includes an integrally molded plastics material member which defines not only the laser focusing lens, but also the laser focusing aperture and the collection mirror. In addition, the molded member may act to house and to locate both a semiconductor laser and a photodetector, thereby ensuring easy and accurate placement of those elements within the scanning assembly. The optical assembly may be in modular form, mounted onto a common printed circuit board with a beam scanner.

摘要： High speed scanning arrangements in scanners for reading bar code symbols by oscillating a scanner component in a single line pattern, the scanner assembly being suspended from a single flexural assembly for oscillating movement. The flexural assembly includes a flexure that lies in a plane extending through a central region of a scan mirror in a direction orthogonal to the plane of the mirror. A drive is operative for moving the scanner assembly from a rest position in a circumferential direction to one of two scan end positions. The flexural assembly is tensioned and stores energy, which energy is released in order to return the scanner assembly in the other circumferential direction to the other scan end position.

摘要： A scanning arrangement for use in an optical scanner, for example a bar code scanner, comprises an optical element which is mounted for oscillation in two directions to produce a two dimensional scanning pattern. The optical element is preferably relatively light, and is mounted for oscillatory motion in an x direction by the flexing of a spring of relatively high modulus of elasticity. The spring is secured to a mounting bracket which itself is mounted to a stationary frame by a further spring which is arranged to flex and cause oscillation in the y direction. The mounting bracket is relatively heavy in comparison with the mirror, and the second spring has a relatively low modulus of elasticity, thereby producing a y oscillation which is slower than the x oscillation.

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.
