See full text

A rotary reciprocating drive actuator capable of increasing the size and amplitude of a movable object such as a mirror, and of stabilizing the drive performance is provided. The rotary reciprocating drive actuator includes a movable part including a rotating shaft, a fixed part supporting the rotating shaft, and a driving part that includes a coil and a core disposed on the fixed part and a magnet disposed on the rotating shaft, and rotates the rotating shaft about the axis thereof with respect to the fixed part by utilizing electromagnetic interaction. The fixed part includes first and second supports disposed so as to face each other with the magnet therebetween in the axial direction. The rotating shaft is rotatably attached to the first and second supports via first and second bearings. One of the first and second bearings is a rolling bearing, and the other is a slide bearing.
