摘要： An image stabilizer includes a rotor including a lens assembly, and configured to move perpendicular to an optical axis of light passing through the lens assembly, and a suspension unit configured to support movement of the rotor and to prevent the rotor from moving non-perpendicular to the optical axis of the light passing through the lens assembly. Accordingly, the image stabilizer prevents variance of characteristics of a rotor in a low frequency band according to the position and distortion of phase characteristics in a high frequency band. Therefore, the image stabilizer has consistent operation characteristics regardless of the position, posture, and movement of a person using an image capture device containing the image stabilizer.

摘要： An objective lens driving apparatus for an optical pickup includes a base (100), a holder (110) provided on the base (100), a blade (120) on which an objective lens (130) is mounted, an elastic support body (140) elastically supporting the blade (120) capable of moving with respect to the holder (110), a pair of magnetic members (150) installed on the base (100) to face each other, and a coil assembly (160) including a focus coil (161), a tracking coil (163), and a tilt coil (162) and installed at the blade (120) so as to be disposed between the magnetic members (150). Thus, since coils needed to change the position of an objective lens (130) are incorporated into a single coil assembly (160) and arranged between a pair of magnets (150), an installation space is small so that the apparatus can be made compact. Also, the control sensitivity can be improved by extending an effective length of a coil by appropriately matching the magnet polarized into two poles and the coil assembly.

摘要： Provided is an apparatus for driving an objective lens of an optical pickup. The provided apparatus for driving a support (120) on which an objective lens (130) is mounted, includes a first electromagnetic unit (210) for generating a first electromagnetic force and a second electromagnetic unit (220) for generating a second electromagnetic force. Therefore, when the first and second magnitudes are the same, the support (120) is driven in a focus direction, and when the magnitudes are different, the support (120) is driven in a tilt direction. Accordingly, a tilt error can be actively controlled so that a laser beam is incident to a disk in a precise direction. Therefore, the qualities of recording and reproducing data are improved. In addition, tilt control is performed by using a focus adjustment mechanism so that an additional mechanism for controlling tilt is not required. As a result, the size and weight of the apparatus for driving the objective lens of the optical pickup are reduced.
