Hand-held scanner apparatus having visual scan region position feedback system |
摘要 |
<p>Scanner apparatus (12) having a visual scan-region position feedback system (10) according to the present invention may comprise a body (30) having at least one elongate opening (24) therein that extends along a transverse axis (26) so that the elongate opening (24) encompasses a scan region (28) on an object (14) during a scanning operation. An image sensing system (44) mounted within the body (30) of the scanner (12) is optically coupled to the elongate opening (24) therein and receives image light reflected by the scan region (28). A first light source (66) mounted to the body (30) produces a first light beam (20) that is generally aligned with the elongate opening (24) in the body (30) and that extends outwardly from the body (30) in a first direction (76) along the transverse axis (26). The first light beam (20) is incident on at least a portion of the object (14) being scanned during the scanning operation and provides a visual indication of a position of the scan region (28) with respect to the object (14) being scanned. <IMAGE></p> |
