Abstract
A microfilm reader comprising a plurality of input keys for specifying the desired frame of a microfilm, drive assemblies for automatically transporting the microfilm in response to signals from input keys to bring the specified frame to the projecting position, and a control system. Upon the application of power to the control system or change of the magnification of projection, a signal output circuit emits signals equivalent to those produced when specific input keys are depressed, to transport the microfilm automatically to a predetermined position and bring a specified frame to the projecting position without striking any input key.
