  • Auto focusing bar code reader
    Patent number: 5192856
    Abstract: A device for reading and interpreting bar codes, which illuminates the bar code with a fixed elliptical beam and images the reflected beam onto a CCD array. The black and white bar information is detected by the electronically scanned elements of a linear CCD array. The limited operational range, determined by the optical system depth of focus, is enhanced significantly to a useful operational range by automatically focusing the image of the bar code on the CCD array.
