Abstract
An optical reading system for reading optically encoded information represented by a symbol on a target includes a rotational shaft, a light emitter for producing a beam of light to scan a path through a scan field, and a light detector for detecting light reflected from the symbol to read the optically encoded information. A means for oscillating the light emitter and light detector about a longitudinal axis of the rotational shaft is also provided. At least one electrical conductor is connected to each of the light emitter and light detector for providing electrical energy thereto. Each electrical conductor is affixed between distal ends thereof at a point coincident with a point on the longitudinal axis of the rotational shaft.
