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.

摘要： An optical deflection apparatus, an image projector, an optical writing unit, and an object recognition device. The optical deflection apparatus includes a mirror unit having a reflection plane, a plurality of actuators to move the mirror unit around a prescribed axis, a drive controller to control operation of the plurality of actuators, and an abnormality detector to detect an abnormality in at least one of the plurality of actuators. When the abnormality detector detects an abnormality in at least one of the plurality of actuators, the drive controller controls another one of the plurality of actuators to deflect a light flux incident on the mirror unit. The image projector includes the optical deflection apparatus, and a light source unit to emit a laser beam. The optical deflection apparatus projects an image formed by optically scanning the laser beam emitted from the light source unit.
