    • PURPOSE: A device for driving lens is provided to reduce power consumption when the lens is driving or a position of the lens is maintained. CONSTITUTION: A device for driving a lens(2) includes a moving body(3) and fixed body. The fixed body moves a moving body(3) in an optical axis direction of the lens(2) between a first lens retaining positions and a second lens retaining position and retains the moving body(3) at the first lens retaining position and the second lens retaining position. The moving body(3) includes the lens and a driving magnet(5) attached to the lens. The fixed body(4) includes a magnetic member. The magnetic member is disposed opposite at least one of two end sections in the optical axis direction of the driving magnet(5). The magnet member includes a first magnet member disposed adjacent to the first lens retaining position and a second magnet member disposed adjacent to the second lens retaining position.

    • A lens driver (1) comprising a moving lens body (10) consisting of a lens-barrel (10b) provided with a lens (14) and a lens-barrel holder (10a) for supporting the lens-barrel (10b) so as to be movable in the direction of the optical axis (11). The lens- barrel holder (10a) has a driving magnet (16) and a case body (24) for supporting the moving lens body (10) so as to be movable in the direction of the optical axis (11) encases first and second driving coils and has an end face (27) of an inner tubular section (26b) and a projecting edge (36) of an inner tubular section (42b) that regulate the moving range of the lens-barrel holder (10a) in the direction of the optical axis (11). The moving lens body (10) is moved by a magnetic attracting force or repelling force of the driving magnet (16) and the first and second driving coils.
    • 一种透镜驱动器(1),包括由设置有透镜(14)的透镜镜筒(10b)和用于支撑透镜镜筒(10b)的透镜镜筒保持器(10a)组成的移动透镜体(10),以便 可沿光轴(11)的方向移动。 透镜筒保持器(10a)具有驱动磁体(16)和用于支撑移动透镜体(10)以便沿光轴(11)的方向移动的壳体(24),该第一和第二 驱动线圈,并且具有内部管状部分(26b)的端面(27)和内部管状部分(42b)的突出边缘(36),该内部管状部分(42b)在镜片保持器(10a)的方向 的光轴(11)。 移动透镜体(10)通过驱动磁体(16)和第一驱动线圈和第二驱动线圈的吸引力或排斥力而移动。

    • PURPOSE: A lens driving device and a portable device attached with a camera are provided to simplify constitution, to reduce the number of parts, to miniaturize a lens driving device, and to decrease power consumption in a lens driving device and a portable device attached with camera without providing electricity to maintain a lens in a certain position. CONSTITUTION: A lens driving device(1) is composed of a movable body(10) having a lens(14) and a fixed body(24) which moves the movable body in the direction of an optic axis(11) of the lens and supports the movable body. The movable body constitutes a driving magnet(16) and one of driving coils(28,30). The fixed body constitutes the driving magnet and the other driving coil. The driving magnet and the driving coils are set up in the direction of the optic axis to move the movable body using the magnetic attractive force or the magnetic repulsive force.
    • 目的:提供一种透镜驱动装置和附带有相机的便携式装置,以简化构造,减少部件数量,使透镜驱动装置小型化,并降低透镜驱动装置和附带有便携式装置的便携装置的功耗 相机不提供​​电力以将透镜保持在特定位置。 构成:透镜驱动装置(1)由具有透镜(14)和固定体(24)的移动体(10)构成,该透镜驱动装置(12)和可移动体沿透镜的光轴(11)的方向移动, 支撑移动体。 可移动体构成驱动磁体(16)和驱动线圈(28,30)中的一个。 固定体构成驱动磁体和另一驱动线圈。 驱动磁体和驱动线圈被设置在光轴的方向上,以使用磁吸力或磁排斥力移动可移动体。
