Abstract
An embodiment of the present invention relates to an actuator device comprising: a housing; a holder which is disposed in the housing; a reflective member which is disposed in the holder; a first drive unit which tilts the holder about a first axis; a first attractive member which is disposed in the holder; and a second attractive member which is disposed in the housing and has attraction with the first attractive member, wherein a first imaginary straight line connecting the center of the first attractive member to the center of the second attractive member is spaced apart from a second imaginary straight line passing through the first axis and parallel to the first straight line.

An actuator device comprising:
- a housing;
- a holder disposed in the housing;
- a reflective member disposed on the holder;
- a first drive unit configured to tilt the holder about a first axis;
- a first attractive member disposed on the holder;
- and
- a second attractive member disposed on the housing and configured to act an attractive force with the first attractive member,
- wherein an imaginary first straight line connecting a center of the first attractive member and a center of the second attractive member is spaced apart from an imaginary second straight line passing through the first axis and parallel with the first straight line.
An actuator device comprising:
- a housing;
- a holder disposed in the housing;
- a reflective member disposed on the holder;
- a first drive unit configured to tilt the holder about a first axis;
- a first attractive member disposed on the holder;
- and
- a second attractive member disposed on the housing and configured to act an attractive force with the first attractive member,
- wherein in an initial state when no current is applied to the first drive unit, the holder is contacted with the housing.
An actuator device comprising:
- a housing;
- a holder disposed in the housing;
- a reflective member disposed on the holder;
- a moving plate disposed between the housing and the holder;
- a driving magnet and a first coil configured to tilt the holder about a first axis;
