CAMERA MODULE HAVING AUTO-FOCUS APPARATUS

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.
