Abstract

A disk film camera which is of simple, compact and inexpensive construction and yet provides one-button operation to expose the film and actuate a motor which disengages the film and cocks the shutter, then advances and locates the film. A demetering cam that is simpler and takes less space in the camera is used to remove the metering pawl from engagement with the film to permit the film to be advanced.
