LASER LIGHT BEAM SCANNING DEVICE FOR READING CODED INFORMATION AND SCANNING OPTICAL ELEMENT FOR SUCH DEVICE

摘要

A laser light beam scanning device for reading coded information comprises an emission source of a laser light beam, an optical element for scanning the laser light beam on a support containing coded information, an optical element for collecting the light coming from the support and photodetector means sensitive to the light collected by the collecting optical element so as to generate a representative signal of the information contained in the support. The collecting optical element is spatially distinct from, and integrally oscillating with the scanning optical element and comprises at least one transmissive input surface of the light coming from the support. In particular, the scanning optical element and the collecting optical element are part of a single scanning and light collecting optical element.
