  • Patent number: 9739974
    Abstract: An interchangeable lens has a lens frame holding a movable lens group, another lens frame holding another movable lens group, one actuator that drives one lens frame, and the other actuator that drives the other lens frame. A first yoke forming a magnetic circuit of the one actuator and a second yoke forming a magnetic circuit of the other actuator are disposed away from each other in an optical axis direction, and a nonmagnetic member is interposed between the first yoke and the second yoke.
    Type: Grant

  • Patent number: 9733449
    Abstract: An interchangeable lens includes a fixing frame in which a front movable lens group and a rear movable lens group are coaxially arranged and movable in the direction of an optical axis. An intermediate member is arranged between a movable range of a lens frame holding the front movable lens group and a movable range of a lens frame 12 holding the rear movable lens group. The intermediate member is a partition between the movable lens groups and prevents interference between them. In addition, the intermediate member blocks undesired light components which are part of the light incident on the fixing frame and traveling from the front movable range to the rear movable range.

  • Patent number: 9338335
    Abstract: A lens drive apparatus includes a yoke which has a first parallel portion parallel to an optical axis and a second parallel portion which is located closer to the optical axis than the first parallel portion, the first and the second parallel portions being magnetically coupled, a magnet arranged at the first parallel portion to extend in the optical axis direction, a first lens frame which has a first coil wound around the second parallel portion and which is guided by a first guide shaft, and a second lens frame, which has a second coil wound around the second parallel portion and which is guided by a second guide shaft, and the first and the second guide shafts are arranged at positions so as not to interfere with the yoke in a cross-section perpendicular to the optical axis.
