    • The invention provides a lens driving device capable of performing zooming and auto-focusing using a single actuator, with a simple and miniaturized structure and less power consumption. The lens driving device includes a first lens disposed movable during zooming and automatic focusing, a second lens disposed movable during zooming independently from the first lens. The lens driving device also includes a lens movement guide member, having a first guide part, and a second guide part, rotated to move the first and second lenses. An actuator is provided to move the first and second lenses, and both the first and second lenses are moved during zooming while only the first lens is finely moved during automatic focusing.
    • 本发明提供一种能够使用单个致动器执行变焦和自动聚焦的透镜驱动装置,其具有简单且小型化的结构和较少的功率消耗。 透镜驱动装置包括可在变焦和自动聚焦期间移动的第一透镜,可独立于第一透镜在变焦期间移动的第二透镜。 透镜驱动装置还包括具有第一引导部分的透镜移动引导部件和旋转以移动第一和第二透镜的第二引导部件。 提供致动器以移动第一和第二透镜,并且在变焦期间第一透镜和第二透镜都被移动,而在自动聚焦期间只有第一透镜被精细地移动。
