Abstract
A camera module includes first to third lens groups; a first mover configured to move the second lens group in the optical-axis direction; a second mover configured to move the third lens group in the optical-axis direction; a base accommodating the first mover and the second mover; a support ball disposed to be in rolling contact with the first mover, the second mover, and the base, the support ball supporting movement of the first mover and the second mover relative to the base; a driving magnet coupled to each of the first mover and the second mover; and a coil part coupled to the base, the coil part being disposed to face the driving magnet, and wherein an entirety of a surface of the driving magnet that faces the moving coil serves as a first pole.
Claims20
A camera module, comprising:
- a first lens group on which light is incident;
- a second lens group disposed so as to be spaced apart from the first lens group in an optical-axis direction;
- a third lens group disposed between the first lens group and the second lens group;
- a first mover configured to move the second lens group in the optical-axis direction;
- a second mover configured to move the third lens group in the optical-axis direction;
- a base accommodating the first mover and the second mover;
- a support ball disposed to be in rolling contact with the first mover, the second mover, and the base, the support ball supporting movement of the first mover and the second mover relative to the base;
- and
- a driving magnet coupled to each of the first mover and the second mover,
- wherein the base includes a mounting portion fixed to and extending upwardly from the base, to which the first lens group is securely coupled.
