Abstract: An optical transducer encoding system for use with mechanical counting means such as intermittent movement type counting mechanisms is illustrated using a stationary support means thereof as a housing for a plurality of transducers which transmit light to reflective means on the web of each one of a plurality indicia wheels and which light is reflected to optical sensors within the stationary support. All the reflective means are at the same radial distance from the hub of the wheel and the transducers provide an encoded electrical output indicative of the indicia readout.
