Abstract
An underwater camera comprising a water-resistant casing, a camera housing contained in the water-resistant casing, a manually rotatable thumbwheel positioned outside the water-resistant casing, and coupling means for rotationally coupling the thumbwheel to a film spool rotatably supported in the camera housing to permit the thumbwheel to be manually rotated to similarly rotate the film spool, is characterized in that the coupling means is a magnetic torque coupling including a driving ring of magnets fixed to the thumbwheel for rotation with the thumbwheel and a driven ring of magnets rotationally engaged with the film spool. The magnets of the driving ring and the magnets of the driven ring are magnetically coupled for synchronous rotation of the driving and driven rings to rotate the film spool when the thumbwheel is rotated.
