Abstract
PURPOSE:To improve a focusing point by constituting a movable lens member and the movable part of an electromagnetic actuator so that they balance with each other like a balancing toy, and stopping both parts at optional positions. CONSTITUTION:The movable lens member 1, the movable part 7 of the electromagnetic actuator 6, and lever members 15 and 16 are constituted balancing like the balancing toy about fixed shafts 20 and 21 as fulcrums. Rotary moment around the axial support part of the lever members 15 and 16 supported pivotally on fixed shafts 20 and 21 is zero regardless of the rotational positions of the lever members 15 and 16 and the rotational positions of the lever members 15 and 16 supported pivotally on fixed shafts 20 and 21 around the axial support part, and the movable lens member 1 and the movable part 7 of the electromagnetic actuator 7 balance with each other. Therefore, no other force is interposed in the movement of the electromagnetic actuator 6 and movable lens member 1, so the motion of the movable part 7 of the actuator 6 becomes the motion of the lens member 1 directly and the lens member 1 stops at the position where the movable part 7 stops moving.
