Abstract
A light emitter emits light through an offset opening in a concave collector to a reflector that reflects the light along a first path to coded indicia to be read in an electro-optical reader. Light reflected from the indicia is reflected by the reflector to the collector which, in turn, directs the reflected light in a second path extending across the first path to a light detector. The reflector is mounted on a resilient spring for oscillating movement.
