Abstract

A cine camera employing interchangeable film magazines with displacement of the spindles of the film take-off and take-up reels, comprises an electric motor mounted on the body of the camera and of which the horizontal driven shaft is fast with a driving magnetic plate of a magnetic coupler which is housed in an opening in the body coaxial with the axis of the motor and of the shaft. The outer front face of the driving magnetic plate is substantially flush with the outer face of the body which is adjacent the outer face of the wall of the casing of the interchangeable magazine. The magnetic coupler comprises, in the magazine, a driven magnetic plate of which the axis merges with that of the driving magnetic plate. The driven magnetic plate is fast with a driving pinion and the driven magnetic plate and the driving pinion are mounted to rotate, in the magazine, about an axis which is merged with the axis of the drive motor. The driving pinion is coupled to a driven pinion which is fast with the spindle of the take-up reel and coaxial therewith and this spindle and the driven pinion are mounted to rotate jointly on a plate which is itself mounted to pivot about the axis of the driven plate/driving pinion assembly.
