Cine camera employing interchangeable film magazines with displacement of the spindles of the film take-off and take-up reels

A cine camera comprising:

• (a) a camera body,
• (b) an interchangeable film magazine attachable to said camera body for supplying unexposed film to the cine camera and for receiving exposed film, comprising:
• a casing;
• a take-off reel longitudinally moveable within said casing, said take-off reel supplying unexposed film to the cine camera;
• a driving pinion within said casing;
• a driven pinion operably connected to said driving pinion by a driving means, said driven pinion longitudinally translatable within said casing along an arc centered about said driving pinion;
• and
• a take-up reel mounted on said driven pinion and coupled to said take-off reel,
• (c) a motor mounted on the camera body external to said casing of the interchangeable film magazine, and
• (d) connection means between said motor and said driving pinion for releasably coupling said motor to said driving pinion for rotating said take-up reel.

• said connection means comprising a magnetic coupler,
• said motor being coupled with a drive shaft to a driving magnetic plate of a driving magnetic coupler disposed in an opening in said camera body;
• said camera body having an outer face and said driving magnetic plate having an outer front face which is substantially flush with the outer face of said camera body;
• said film magazine including a driven magnetic coupler in a side wall of said casing, said magnetic coupler including a driven magnetic plate disposed in an opening in said side wall, said driven magnetic plate having an outer front face flush with an outer face of the side wall of said film magazine;
• and
• said driven magnetic plate and said driving magnetic plate being coaxial and magnetically attaching to one another when said film magazine is attached to said camera body.

A film magazine for supplying unexposed film to a cine camera and for receiving exposed film, comprising:

• a casing;
• a driving pinion within said casing, said driving pinion releasably coupleable to a motor external to said casing via a connector;
• a driven pinion operably connected to said driving pinion, said driven pinion being longitudinally translatable within said casing along an arc about said driving pinion, said driving pinion being positioned at a center of curvature of the arc;
• a take-off reel longitudinally movable along a path separate from the arc of the driven pinion within said casing, said take-off reel supplying unexposed film to the cine camera;
• and
• a take-up reel mounted on said driven pinion and coupled to said take-off reel,
• wherein said connector comprises a magnetic coupler,
• said motor being coupled with a drive shaft to a driving magnetic plate of a driving magnetic coupler disposed in an opening in said camera body,
• said camera body having an outer face and said driving magnetic plate having an outer front face which is substantially flush with the outer face of said camera body,
• said film magazine including a driven magnetic coupler in a side wall of said casing, said magnetic coupler including a driven magnetic plate disposed in an opening in said side wall, said driven magnetic plate having an outer front face flush with an outer face of the side wall of said film magazine, and
• said driven magnetic plate and said driving magnetic plate being coaxial and magnetically attaching to one another when said film magazine is attached to said camera body.
