Abstract: A stereoscopic camera system is disclosed which includes an insertable film cartridge. An optical system in the camera includes mirrors which are arranged to reflect images from the lenses along coincident axes through aperture plates for exposing sensitized film carried by the cartridge. The cartridge includes a housing forming a supply chamber for containing a roll of the film. Another chamber is provided in the housing for enclosing a take-up spool which is adapted to be driven for advancing the film along a transport track formed about the rim of the housing. A pair of pressure plates are mounted in the housing adjacent the portions of the film which are to be exposed by the light images. Means is provided for yieldably urging the pressure plates against the film so that the latter is maintained in flat relationship against the aperture plates.
