Actuator for driving reflector

Abstract

An actuator for driving a reflector includes a movement frame including a reflector configured to reflect or refract light to a lens and a first magnet, a first support frame configured to provide a space of the movement frame to move, a first drive coil configured to generate an electromagnetic force in the first magnet to rotationally move the movement frame in a first direction based on the first support frame, a first rotation guide between the movement frame and the first support frame and having an arc shape so that the movement frame rotates in the first direction, and a first ball inside the first rotation guide, in which a center of curvature of the first rotation guide corresponds to a center of rotation of the reflector.

Dependencies are inferred from the claim text.
