摘要： Disclosed herein is an image stabilization mechanism for a camera module. The image stabilization mechanism includes a base, a movable stage receiving a lens barrel therein and having a magnet, and a piezoelectric actuator. The piezoelectric actuator is installed to the base, moves the movable stage in an X-axis or Y-axis direction to remove shake of the lens barrel, and maintains contact with the movable stage because of magnetic attractive force between the piezoelectric actuator and the magnet. The image stabilization mechanism reduces the number of components, thus simplifying the structure and minimizing an increase in height.

摘要： The present invention discloses a camera module having an auto-focus apparatus including: a piezoelectric actuator for generating a force for moving a driven member; a rod connected to the piezoelectric actuator and transmitting the force of the piezoelectric actuator to the driven member; a lens barrel having at least one lens; and a connecting member for coupling the rod and the lens barrel together by a magnetic force. The connecting member has a rod guide groove corresponding to the rod and the rod is inserted and coupled to the rod guide groove in a movable manner. Since the lens barrel as a driven member is magnetically coupled to the rod which is adapted to move by the piezoelectric actuator, it is possible to easily assure the tilting performance of lens while securing and maintaining a preload. In addition, the overall size of the camera module can be reduced.
