Lens Moving Apparatus |
摘要 |
An embodiment includes a bobbin provided at an outer circumferential surface thereof with a first coil, a first position sensor disposed on the outer circumferential surface of the bobbin and spaced apart from the first coil, a first magnet disposed so as to be opposite to the first position sensor, a second magnet disposed so as to be opposite to the first coil, the second magnet being configured to move the bobbin in a direction parallel to an optical axis via electromagnetic interaction with the first coil, a housing configured to support the first magnet and the second magnet; and upper and lower elastic members coupled to the bobbin and the housing, wherein the first position sensor is moved along with the bobbin. |
