  • Camera module
    Patent number: 9197802
    Abstract: There is provided a camera module including: a lens barrel including at least one lens disposed on an optical axis; a housing having the lens barrel disposed therein; and first and second elastic members elastically supporting upper and lower portions of the lens barrel, respectively, wherein the first and second elastic members include a fixed side coupled to the housing and a driving side coupled to the lens barrel, respectively, the fixed side and the driving side being disposed to face each other based on the optical axis.
    Type: Grant
    Filed: October 17, 2013
    Date of Patent: November 24, 2015
    Assignee: Samsung Electro-Mechanics Co., Ltd.
    Inventors: Oh Byoung Kwon, Sung Hoon Kim, Kyeong Jun Kim, Yoo Chang Kim
  • Camera module and autofocus method thereof
    Patent number: 9086613
    Abstract: A camera module in which a focal distance is adjusted by an actuator may include a permanent magnet and a coil. A neutral zone spatially dividing first and second polarities of the permanent magnet may be formed at a portion of the permanent magnet facing a sensing sensor sensing magnetic flux.

  • Actuator, stage device, and exposure apparatus
    Patent number: 8593616
    Abstract: An actuator according to example embodiments may be relatively compact and may be driven with 2 degrees of freedom with less spatial constraints. The actuator may include a base member, a ball screw member including a ball screw coupled to the base member and a ball nut screwed onto the ball screw, a driving member coupled to the ball nut so as to move in conjunction with the ball nut, a first directional displacement member configured to move in a first direction in response to a first movement of the driving member, a wedge member coupled to the driving member so as to be moved in a second direction in response to a second movement of the driving member, a second directional displacement member configured to move in a second direction in conjunction with the wedge member, and a binding member configured to bind the first directional displacement member to at least one of the driving member, the wedge member, and the base member.
