Integral, planar electromagnetic camera element/actuator |
摘要 |
An exposure regulating element for a photographic camera is formed from a one piece sheet of light weight, non-magnetic, electrically conductive metal to provide a light regulating blade, a flexure hinge for urging the blade toward an initial aperture covering position and a conductor coil which cooperates with a permanent magnet for generating a force to move the blade away from the initial position. In a preferred embodiment a pair of exposure regulating elements each providing integral light regulating, flexure hinge and conductor coil means move in opposite directions to cover and uncover an exposure operation.
