LIGHT BEAM SCANNING PEN, SCAN MODULE FOR THE DEVICE AND METHOD OF UTILIZATION

摘要

A high speed non-contact beam scanning device (20) sized and shaped to provide the ergonomic benefits of a pen or wand (1). The device is well suited for reading one or two dimensional bar-code (9, 10) or other printed matter. In order to achieve the high density optical packaging necessary for its high performance to size benefits, the device employs a novel in-line or "axial" gyrating, or "axial" scan element. Reflected light, which carries information contained on the target, is collected by an internal non-imaging light concentrator (34) and is processed by signal processing electronics (24). Communication from the device is achievable by a cable or by wireless communication technique.
