摘要： A method of operating an indicia reader for reading information bearing indicia (IBI) positioned in a field of view of the reader includes: transmitting a first laser light beam adapted for scanning an IBI on a target located a first distance from the indicia reader; transmitting a second laser light beam adapted for scanning an IBI on a target located a second distance greater than the first distance from the indicia reader; activating at least one of the first and second laser light beams; scanning at least one of the laser light beams with a flat unitary scan mirror to generate at least one of a first laser light beam pattern and a second laser light beam pattern; directing light reflected from the target from either the first or second laser light beams patterns through a common receive path; the common receive path including being reflected with the flat unitary scan mirror onto a focusing mirror; the focusing mirror directing reflected light along a directed reflected light path; the directed reflected light path including an optical filter outputting directed reflected light; converting the directed reflected light into an output signal with a photodetector; decoding IBI information derived from the output signal, wherein the operating steps are completed by devices supported in a hand held indicia reader housing and wherein an operator selectively activates the first laser light beam and/or the second laser light beam with a single action trigger.

摘要： A scan element includes a bobbin having a central axis about which is wound an electromagnetic wire coil and having a flange oriented generally transverse to the central axis. At least one elastomeric support has a first end coupled to the flange. A permanent magnet has first and second surfaces, a central axis, and a magnetization direction oriented generally transverse to the central axis of the permanent magnet. The magnet is supported by a second end of the elastomeric support. A mirror has a central axis and is mounted on the second surface of the magnet. The central axes of the mirror and magnet are coaxial with the central axis of the bobbin. The elastomeric support provides a return force when the magnet and the mirror are rotated at an angle from the central axis during energization of the electromagnetic wire coil.
