  • Patent number: 8896711
    Abstract: The present invention is an anti-vibration actuator (10) for moving an image stabilizing lens (16), having: a fixed portion (12); a movable portion (14) to which an image stabilizing lens is attached; a movable support member (18) for supporting this movable portion so that it is movable within a plane perpendicular to the optical axis of the image stabilizing lens; drive coils (20) attached to one of either the fixed portion or the movable portion; drive magnets (22) attached to the other of either the fixed portion or the movable portion so as to respectively face these drive coils; and at least one yoke (26) disposed on the side of the drive coils not facing the drive magnets; whereby magnetic force suppressing cutouts (26a) are provided on the yoke in a position overlapping the drive coils in order to suppress magnetic force received from the drive coils.

  • Patent number: 8284508
    Abstract: An imaging lens for adjusting a position of an adjusting lens to be carried out easily and which has an improved impact resistance. The imaging lens includes a lens frame for supporting a lens serving as an adjusting lens and a support frame for supporting the lens frame. A contact section for support frame adjustment operable to come into contact with the lens frame is arranged in the support frame. A contact section for lens frame adjustment operable to come into contact with the support frame is arranged in the lens frame. The lens frame is configured such that the fastening force generated between the lens frame and the support frame can be applied vertical with respect to the contact section for support frame adjustment in a state of the contact section for lens frame adjustment held in contact with the contact section for support frame adjustment.

  • Patent number: 7573653
    Abstract: The present invention is directed to an inner focusing zoom lens barrel provided with cams of a well-balanced configuration for smooth zooming and/or focusing operations, which attains sufficient performances at the minimum object distance, which is capable of inhibiting a focal length from varying throughout the entire zoom range, and which has a reduced outer diameter. The inner focusing zoom lens barrel has a fixed barrel, first and second cam barrels, a linear-shuttle barrel, a focusing cam barrel, a zooming relay barrel, and a 1st-lens-group sliding barrel, characterized in that the first cam barrel, the linear-shuttle barrel, and the focusing cam barrel are superposed one over another in this sequence inside the fixed barrel while the zooming relay barrel, the second cam barrel, and the 1st-lens-group sliding barrel are superposed one over another in this sequence outside the fixed barrel.
