    • A lens drive device for a zoom optical system drives first and second lenses along an optical axis with a single drive source. A transmission mechanism connects the drive source and the first and second lenses. The transmission mechanism transmits drive to the first lens during a first motion range and to the first and second lenses during a second motion range. A focal length of the optical system changes in the first motion range and a focal point position of the optical system changes in the second motion range. The first and second lenses respectively moves in response to movement of a first and second feed screw. A first gear transmits drive from the drive source to the first feed screw while a second gear intermittently transmits drive from the drive source to the second feed screw. A lock lever interlocks with the second gear in response to rotation of a large diameter section of the first gear to thereby arrest movement of the second gear and second feed screw. A spring urges the lock lever into contact with the second gear.
    • 用于变焦光学系统的透镜驱动装置利用单个驱动源沿光轴驱动第一透镜和第二透镜。 传动机构连接驱动源和第一和第二透镜。 传动机构在第一运动范围内将驱动传递到第一透镜,并且在第二运动范围内将驱动传递到第一和第二透镜。 光学系统的焦距在第一运动范围内变化,并且光学系统的焦点位置在第二运动范围内变化。 第一和第二透镜分别响应于第一和第二进给螺杆的移动而移动。 第一齿轮将驱动器从驱动源传递到第一进给螺杆,而第二齿轮将驱动器从驱动源间歇地传递到第二进给螺杆。 响应于第一齿轮的大直径部分的旋转,锁定杆与第二齿轮联锁,从而阻止第二齿轮和第二进给螺杆的运动。 弹簧促使锁定杆与第二档啮合。
