摘要： A device for conveying a motion picture film has at least one uniformly distributed row of perforations. An unwinding toothed reel, which continuously unwinds the motion picture film from a film supply reel, a winding toothed reel that continuously winds the motion picture film onto a film winding reel, and a film feeding mechanism, which intermittently conveys the motion picture film, engage inside said perforations. In order to switch the film conveyance from three to four perforation holes per film frame, the rotational speed of the film conveying motor connected to the winding toothed reel and to the unwinding toothed reel, is increased by 4:3, whereas the multiplication of the film feeding mechanism, of the movement gearing or of a movement gearing element can be altered by three or four perforation holes per film frame in order to adapt to the conveyance of the motion picture film.

摘要： The invention relates to a motion picture camera having a camera lens, a gate disposed through a film path of a motion picture film, past which gate the motion picture film is moved intermittently by means of a film transport mechanism. A shutter is disposed between the camera lens and the gate. A capping shutter is disposed in front of the gate in the optical path between the shutter and the film which provides for a light-tight covering of the motion picture film during single-frame exposure or time exposures.
