Abstract
An exemplary embodiment of the present invention a rotor including a lens and formed with a first driving unit, a stator formed with a second driving unit driving the rotor in response to electromagnetic interaction with the first driving unit, and a base on which the stator is fixed, wherein the rotor is brought into contact with the base, in a case the lens is in a UP posture, and the rotor is distanced from the base, in a case the lens is in a DOWN posture.
Claims25
A camera module, the camera module comprising:
- a rotor including a lens and formed with a first driving unit;
- a stator formed with a second driving unit driving the rotor in response to electromagnetic interaction with the first driving unit;
- and
- a base on which the stator is fixed,
- wherein the rotor is brought into contact with the base, in a case the lens is in a UP posture, and the rotor is distanced from the base, in a case the lens is in a DOWN posture.

A VCM (Voice Coil Motor), the VCM comprising:
- a rotor including a first driving unit arranged at a periphery of a bobbin fixing a lens;
- a stator including a second driving unit opposite to the first driving unit and a housing fixing the second driving unit;
- an elastic member coupled at one side to the rotor and coupled at the other side to the stator;
- a base supporting the stator and having an opening exposing the lens;
- and
- a case covering the housing and being coupled to the base,
- wherein an interference prevention unit is formed at any one of the case and the housing to prevent a part of the elastic member from interfering with the case or the housing, in a case the rotor ascends or descends relative to the stator.
