A camera device comprising:
- a stationary unit;
- a moving plate disposed on the stationary unit;
- a first moving unit disposed on the moving plate, the first moving unit comprising an image sensor;
- a second moving unit disposed in the first moving unit, the second moving unit being movable in an optical-axis direction;
- first ball members disposed between the first moving unit and the moving plate and spaced apart from each other in a direction parallel to a first axis that is perpendicular to the optical-axis direction;
- second ball members disposed between the moving plate and the stationary unit and spaced apart from each other in a direction parallel to a second axis that is perpendicular to the first axis;
- and
- a first driving unit configured to tilt the first moving unit and the second moving unit about the first axis or the second axis
- wherein the first driving unit comprises:
- a first coil unit and a first magnet unit disposed to be in parallel to the second axis;
- and
- a second coil and a second magnet unit disposed to be in parallel to the first axis.
