PHOTOMECHANICAL CAMERA

A photomechanical camera for use with a roll film has a vacuum suction box disposed in a camera housing and having a perforated front wall facing the lens system of the camera. An endless conveyor belt of a perforated material extends around the suction box and has a front run extending in substantially parallel and close contact relationship with the suction box front wall so that air is sucked into the suction box through the perforations in the belt and the suction box front wall. A length of film severed off and fed from the roll film onto the front run of the conveyor belt is sucked against the belt in the front run thereof and is conveyed toward an exposure position in which the center of the length of film in alignment with the optical axis of the lens system. Drive of the belt is so controlled that the motion of the belt is interrupted when the length of film is reached by the exposure position whereby the film is retained by the vacuum force in the exposure position during the exposure thereof.
