  • Patent number: 4500870
    Abstract: A utility meter has a plurality of rotating shafts which have angular positions corresponding to the digits of a consumption reading. A cam is attached to that shaft which is associated with the least significant digit. The cam has a light reflecting track. Light from a light source is reflected off the track to a photodetector along an optical path which varies in length in accordance with angular cam position. Electronic circuitry is connected to the light source and photodetector and produces an output signal in digital form which has a frequency related to intensity of light incident upon the photodetector.
