Abstract:
In a bar code reader having a light emitter for emitting a light beam toward a bar code symbol for reflection therefrom, and a detector for detecting light reflected from the symbol, a compact bar code symbol scanning assembly, comprising:a) a stationary support;b) a scan mirror for reflecting the light beam incident thereon toward the bar code symbol to be scanned;c) a flexure having stationary portions fixed to the stationary support, and a movable portion between the stationary portions and operatively connected to the scan mirror to support the scan mirror for movement relative to the stationary support; andd) an energizable electromagnetic drive for moving the scan mirror, including a permanent magnet for generating a permanent magnetic field, and an electromagnetic coil for generating a magnetic field that interacts with the permanent field in response to an energizing drive signal through the coil, one of the magnet and the coil being mounted on, and symmetrically arranged relative to, the scan mirror for joint balanced movement with the scan mirror relative to the stationary support to scan the light beam over the symbol.
