    • PROBLEM TO BE SOLVED: To provide a lens drive device that is easy to manufacture, less in blockage of drive of a lens support, and able to move the lens support in the direction of an optical axis and shift correction of hand shake, and to provide an auto-focus camera and a mobile terminal device with camera.SOLUTION: Each magnet 17 faces the peripheral face of a first coil 19 and, in the position where second coils 16 and 18 are provided, each magnet 17 faces the second coils 16 and 18. A spring 9 on one side and a spring 11 on the other side are composed of separate springs 20, 21, and 40 to 43 and have six springs in all. The coil ends of the first coil 19 and the second coils 16 and 18 are connected to the different springs 20, 21, and 40 to 43 respectively. To move the lens support 5 in the direction of the optical axis, a current is caused to flow in the first coil 19. To move the lens support 5 in an X-Y direction orthogonal to the optical axis, a predetermined current is caused to flow in the given second coils 16 and 18.
    • 要解决的问题:为了提供一种容易制造的透镜驱动装置,较少阻挡透镜支架的驱动,并且能够在光轴方向上移动透镜支架并移动手抖动 并且提供具有相机的自动对焦相机和移动终端装置。 解决方案:每个磁体17面对第一线圈19的外周面,并且在设置有第二线圈16和18的位置中,每个磁体17面向第二线圈16和18.一侧的弹簧9和 另一侧的弹簧11由单独的弹簧20,21和40至43组成,并且全部具有六个弹簧。 第一线圈19和第二线圈16和18的线圈端分别连接到不同的弹簧20,21和40至43。 为了沿着光轴的方向移动透镜支架5,使电流在第一线圈19中流动。为了在与光轴正交的XY方向上移动透镜支架5,使预定电流流入 给定的第二线圈16和18.版权所有(C)2012,JPO&INPIT
