Abstract
A continuous microfilming camera wherein the film is trained over a large driven roller so that its emulsion-coated side faces a lens which is installed in a tubular mount. The roller is rotatable about a fixed axis and the mount is reciprocable in the housing of the camera substantially radially of the roller. Two positioning rolls at the front end of the mount contact the emulsion-coated side of that portion of the film which is trained around the roller and are biased against the emulsion-coated side by springs which react against the housing and bear against the mount. The rolls are disposed at the opposite sides of the optical axis of the lens, and the driven roller cooperates with two guide rollers which insure that the film is trained over the major part of the peripheral surface of the driven roller.
