Scan pattern generator for bar code symbol readers. |
摘要 |
<p>Multiple scan line pattern generators including bidirectional scan patterns of mutually parallel scan lines, and scan patterns composed of intersecting lines, are superimposed over bar code symbols to be read. At least one of the scan lines is automatically moved closer to and further away from a reader to perform a zooming function to read far-out and close-in symbols.</p> |
