Abstract
PURPOSE:To obtain an optical system moving device in which a cam cylinder is unrequired and assembling is performed easily and a cost is reduced by employing a moving mechanism consisting of a screw shaft and a screw member instead of the moving mechanism consisting of the cam cylinder. CONSTITUTION:When the shaft of a motor 1 is rotated in a clockwise direction, a gear 3 is rotated in a counterclockwise direction, and revolutional torque in the counterclockwise direction is applied on a planet gear 37 having a shaft 38 supported by the gear 3. Thereby, a sun gear 35 having a large gear 9 engaged with the small gear 5 of the planet gear 37 starts to rotate in the counterclockwise direction. Therefore, since a gear 15 is rotated in the clockwise direction, a gear 14 in the counterclockwise direction, a gear 18 in the clockwise direction, and a gear 19 in the counterclockwise direction, respectively, the screw shaft 30 is turned in the counterclockwise direction, and lens holders 20 and 21 are moved forward simultaneously without changing mutual interval. In such a way, it is possible to make the cam cylinder unnecessary and to simplify the structure of the device, and also, to facilitate the assembling and to lower the cost.
