Method and apparatus for recognizing code information










Image Number 2 for United States Patent #4136821.

A light source, a converging lens and a light responsive image sensor are optically coupled to recognize the code information such as bar codes recorded on an object. The light source supplies the code information with illumination light and the image sensor receives the reflected light through the converging lens to convert it into the image signal. The distance between the lens and the image sensor is adjusted automatically in response to the image signal such that clear reflected light is received by the image sensor, whereby correct information recognizing operation is attained.
