Reader for reading machine-readable symbols, for example bar code symbols |
摘要 |
A machine-readable symbol reader for reading machine-readable symbols such as barcode symbols employs a first reflective surface having a first perimeter to create a pointer beam, and a movable second reflective surface with a second perimeter small than the first perimeter to create a scanning beam. The pointer and scanner beams may exist simultaneously and may be formed from a same illumination beam.
