A microfilm reader has a film transport mechanism driven by separate forward and reverse motors. When the forward motor first starts, power may be applied, via a one way clutch, to a capstan in order to automatically thread the film into the reader. A film gate opens as the film approaches it and thereafter closes, after the film is captured therein. A manual override gate control may prop the film gate open, if film is manually fed through the system.
