  • Barcode width measurement system
    Patent number: 4411016
    Abstract: A single columnar array of scanning diodes is used to make width measurements of bar codes in order to read the contents thereof. The bar code is scanned utilizing a scanning procedure which directs the columnar array along the bar code such that the photo elements on the scanning array lie along an axis parallel to a line drawn horizontally through the bar codes. The same scanning array may be used to read alphanumeric characters scanning along an axis perpendicular to the columnar array.
