摘要： A camera module includes a housing; a lens module provided in an internal space of the housing to be movable in an optical axis direction, and including at least one lens therein; a magnet disposed in the lens module; and position detection sensors to detect a position of the magnet. One or more of the position detection sensors are disposed to face a first polarity of the magnet and one or more of the position detection sensors are disposed to face a second polarity of the magnet different than the first polarity.

摘要： A camera module includes a housing defining an internal space; a reflection module disposed in the internal space and including a reflective member and a holder movably supported by an inner wall of the housing; and a lens module provided in the internal space, and including lenses aligned in an optical axis direction so that light reflected by the reflective member is incident to the lenses. The lens module includes lens barrels accommodating the lenses, and the plurality of lens barrels move in an approximate optical axis direction in the internal space while being supported by ball bearings. At least two of the lens barrels share a guide groove to guide movements of the ball bearings.

摘要： A camera module includes: a housing; a rotation holder configured to tilt about an axis perpendicular to an optical axis with respect to the housing, and accommodating a reflective member; a first magnetic member disposed in the rotation holder; a middle guide disposed between the housing and the rotation holder; and a first ball group including three ball members disposed between the rotation holder and the middle guide. An inner region of a triangle connecting the three ball members of the first ball group to one another and the first magnetic member overlap each other in a direction of the optical axis.
