Abstract
The main body of the actuator structure is generally formed into a 'pitchfork'shape. The middle bar of the pitchfork forms a Y-bend at its forward end. The Y-bend is disposed so that each tip of the bend is adjacent to the outer bar on each side of the pitchfork. At least a coil is fixed on each bar of the main body. The forward ends of the Y-bend abut against a movable member. In the structure above, applying a current to a coil generates minute movements in each tip of the Y-bend, thereby moving the movable member.
