MINIATURE BARCODE SCANNING MODULE FOR A BARCODE READING DEVICE

摘要

A barcode scanning module for a barcode reading device includes a light source for generating a beam of light, a first light collecting mirror having a first surface curvature, a second light collecting mirror having a second surface curvature, and a light receiving assembly for receiving light reflected by a barcode in response to being scanned by the beam of light generated by the light source. The first and second surface curvatures of the first and second light collecting mirrors, respectively, may be generally perpendicular to one another to direct the light reflected by the barcode at the light receiving assembly. The first optics assembly can also include a torsion bar assembly for allowing the first optics assembly to oscillate and vibrate to scan the barcode with the beam of light generated by the light source.
