MICROFILM CAMERA SYSTEM WITH ALTERNATIVE FILM FORM CAPABILITY

摘要

Apparatus for handling photographic film having a first format and alternatively photographic film having a second format different from the first format comprises photographic imaging equipment has a first unit including a first photographic lens system and an integral first extension for defining a first image aperture, and a second unit including a second photographic lens system and an integral second extension for defining a second image aperture. A film pressure plate clamps photographic film having the first format and photographic film having the second format alternatively against the mentioned first extension and against the mentioned second extension. A device is coupled to the film pressure plate for actuating said pressure plate relative to the first extension and alternatively relative to the second extension. These actuating means are mounted in a stationary relationship relative to equipment for releasably mounting the first unit and alternatively the second unit. Photographic film having the first format and alternatively photographic film having the second format is guided past the film pressure plate by equipment mounting on a carriage which is movable relative to the film pressure plate. Film guiding means include a film guide base on the carriage in the vicinity of the film pressure plate and two exchangeable film guide units for guiding, respectively, film having the first format and film having the second format.
