An illumination distribution system for a microrecord reader in which information is optically extracted from the microrecord by a lens array. The microrecord is formed by a plurality of data sets recorded on a record medium, each set representing a reduced scale image of a distinct page of intelligence and being dissected into a multiplicity of data sub-sets which are dispersed on the medium. The illumination distribution system is constituted by a plurality of light-conducting fibers each acting to conduct light derived from a common source to a respective sub-set thereby illuminating the sub-sets of a data set from which information is being extracted, the remaining areas of the microrecord being un-illuminated, thereby avoiding the waste of the available light energy and conserving power.
