Abstract
A major design and development program was undertaken to evolve a substantially new configuration 16mm handheld camera. This camera was designed to comply with present military requirements for a lightweight, self-powered camera for use by combat cinematographers. With performance specifications comparable to existing professional studio equipment, the magazine-loaded camera was to feature a crystal-controlled motor and a pin-registered film-transport mechanism. Early in the development phases of the program, several unusual features were “frozen” into the design, which had a significant effect on the internal configuration of the camera. These features included a combined motor and shutter, in which the rotor of the hysteresis synchronous motor is a cobalt annulus laminated to the periphery of the shutter “wheel.” The claw-type film-transport mechanism design criteria are defined and evaluated.
