    摘要： Several different embodiments are disclosed of a simple, compact bar code scanner which is capable of scanning in any one of several modes, a linear scan mode for scans along a single axis, an omnidirectional scan mode for scans with consecutive scan lines which are angularly displaced relative to each other, or a raster scan mode for scans with consecutive scan lines along a first scan axis which are displaced relative to each other along a second perpendicular axis. In a preferred embodiment, the compact bar code scanner is used in a small housing mounted on an index finger of an operator such that the natural pointing direction of the index finger aims the scanner. In one embodiment, a high frequency flexural member, with a scanning mirror and permanent magnet mounted thereon, is supported by a low frequency flexural member. An x drive coil is positioned by the permanent magnet, and with an applied high frequency x drive signal, causes the high frequency flexural member, with the permanent magnet means and scanning mirror mounted thereon, to torsionally oscillate at the frequency of the x drive signal. A y drive coil is also positioned by the permanent magnet, and with an applied low frequency y drive signal, causes the low frequency flexural member to oscillate to cause low frequency y scanning of the scanning mirror, thereby resulting in a raster scan pattern. With an applied high frequency y drive signal, the y coil causes the high frequency flexural member to oscillate at a high frequency to cause high frequency y scanning of the mirror, thereby resulting in an omnidirectional scan patterns.

    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.
