Patent ID: 7912361

Claim:
An image stabilizing apparatus for a camera module comprising: an automatic focusing unit including a plurality of slide grooves with lengths in an X axial direction or in a Y axial direction, the X and Y axial directions each being perpendicular to an optical axis of the automatic focusing unit, the slide grooves being on a bottom surface of the automatic focusing unit; a driving unit moving the automatic focusing unit in the X axial direction or the Y axial direction; a ball holder which is installed on the bottom surface of the automatic focusing unit and includes a plurality of upper balls slidably coupled to the slide grooves of the automatic focusing unit on a top surface of the ball holder and a plurality of lower balls on a bottom surface of the ball holder; a lower guide which is installed on the bottom surface of the ball holder and includes a plurality of slide grooves on a top surface of the lower guide, wherein the slide grooves of the lower guide are slidably coupled with the lower balls of the ball holder and include lengths in the Y axial direction or the X axial direction and perpendicular to a longitudinal direction of the slide grooves of the automatic focusing unit; a lower housing installed at a lower part of the lower guide; an upper housing coupled to the lower housing to surround the automatic focusing unit; and an image sensor mounted on an inside of the lower housing.
