ABSTRACT:
A photographic camera wherein a film metering sprocket undergoes respective cylces of rotation in each of two opposite directions when a filmstrip is advanced substantially a frame increment in reverse directions over the metering sprocket, and an operating element is actuated to perform a camera function when the metering sprocket is rotated a cycle in one of the opposite directions but is not actuated for such purpose when the metering sprocket is rotated a cycle in the other direction, is characterized in that the metering sprocket and the operating element are disposed in a coaxial relation and include one-way motion transmitting means which when the metering sprocket is rotated a cycle in the one direction engages to compel the metering sprocket to rotate the operating element continuously in the same direction but which when the metering sprocket is rotated a cycle in the other direction does not engage in order to permit the metering sprocket to rotate independently of the operating element.
