Abstract
A camera element position detecting assemblage for a camera element supported for movement to a plurality of positions is characterized by force exerting means for exerting a variable force which is changed in accordance with changes of position of the camera element. Also, position detecting means is provided for sensing a change of force of the force exerting means when the camera element undergoes a change of position, and for substantially determining the particular position of the camera element responsive to the change of force of the force exerting means.
Claims4
