<p>PHOTOGRAPHIC CAMERA In a still camera of the 110-format cassette type, an electric motor is provided for winding on the film and thereby priming the shutter by means of a mechanism which engages a perforation in the film as it passes and moves a shutter priming member. A switch then disconnects power to the electric motor and the camera is ready to expose the next frame of film. In the event that the camera is operated without a film cassette inserted, a trigger mechanism is provided which directly primes the shutter via a gearing mechanism from the motor. When a film cassette is inserted in the camera, the trigger mechanism is inhibited and the shutter is primed only by the passing of a film perforation. Such an arrangement provides a very compact camera and allows the inclusion of an electronic flash unit, if desired.</p> |
