Abstract:
Scanner apparatus having a visual scan-region position feedback system, comprising:a body having at least one elongate opening therein that extends along a transverse axis, the elongate opening encompassing a scan region on an object during a scanning operation;an image sensing system mounted within said body and optically coupled to the elongate opening therein so that image light reflected by the scan region is incident on said image sensing system; anda first light source mounted to said body, said first light source producing a first light beam that is generally aligned with the elongate opening in said body and that extends in a first direction along the transverse axis, the first light beam being incident on at least a portion of the object being scanned during the scanning operation to provide a visual indication of a position of the scan region with respect to the object being scanned.
