Abstract
A sub-miniature camera has a rotatable winding knob which moves the film and cocks the shutter of the objective. A slide is movable by the knob between initial and end positions and blocks a release button from actuation when the slide is in its initial position and releases the button when the slide is in its end position. The slide is provided with a slot through which passes a rod of the release button and the slot and rod co-act to block and unblock the release button. The shutter is operated electrically by contact means closed by the slide moving to its initial position. The slide also actuates an exposure counter and the exposure counter is returnable to the zero counting position upon opening of the camera housing.
Claims15
In a camera, the combination of a rotatable winding knob to move film in the camera and to cock a shutter of an objective, a slide operatively connected to said winding knob and displaceable between initial and end positions, a spring connected to said slide to urge the slide into the initial position, a release button blocked from actuation by said slide in its inital position and released for actuation when the slide is in its end position, means co-acting between said release button and said slide for releasing said slide for displacement to its initial position under action of said spring upon actuation of said release button, and electric contact means closed by said slide returning to its initial position for actuating a circuit to operate a shutter of a camera.
