Abstract
Scanner apparatus having a visual scan-region position feedback system according to the present invention may comprise a body having at least one elongate opening therein that extends along a transverse axis so that the elongate opening encompasses a scan region on an object during a scanning operation. An image sensing system mounted within the body of the scanner is optically coupled to the elongate opening therein and receives image light reflected by the scan region. A first light source mounted to the body produces a first light beam that is generally aligned with the elongate opening in the body and that extends outwardly from the body in a first direction along the transverse axis. The first light beam is incident on at least a portion of the object being scanned during the scanning operation and provides a visual indication of a position of the scan region with respect to the object being scanned.
