A plurality of random access microform recovery units holding a plurality of separate transparencies in a non-reading position, each transparency at a different serial position along a reading path for light. Each transparency has at least one image for modulating light. A collimated beam of light is directed along the reading path and the path may be moved to a desired one of a plurality of parallel path positions when the transparency contains more than one image. A carrier selectively moves any one of the transparencies at its respective serial position into a reading position wherein the image thereon modulates the light beam. The modulated light beam impinges on a radiation sensor and the image is reproduced thereby as an electronic image signal. The image signal is retained in a buffer channel for conversion to visual information. A plurality of input/output stations are used to provide for a time-sharing of the random access recovery unit.
