OPTICAL SCANNER |
摘要 |
<p>An optical scanner is improved by securing beam directing holograpic films to the transparent scanner window. The films alter the paths of beams at the window to provide scanning beams suitable for rear or side scanning of label-carrying products. A vertical scanning beam, which sweeps a path parallel to the window's leading edge, might be used to detect the approach of a product to be scanned.</p> |
