摘要：
An actuator device includes a frame, a movable member to rotate about a rotation axis, a reflection member formed on the movable member to reflect a light flux that enters the reflection member, a first deformable member disposed on the frame to support and move the movable member, at least one first driver to deform the first deformable member, a detection-use line formed on the first deformable member and on the movable member to allow an electric current, and a light shield unit disposed at least one of a light incident side and a light exit side of the reflection member. The light shield unit blocks at least one of an entry of the light flux to the reflection member and an exit of the light flux from the reflection member when the detection-use line is damaged.
