  • Patent number: 10928644
    Abstract: In a case where a first coil enters an energized state, the first coil, a second coil, a detection magnet, and a Z-axis position sensor move in an X axis direction. In a case where the second coil enters an energized state, the second coil and the detection magnet move in a Z axis direction, but the first coil and the Z-axis position sensor do not move in the Z axis direction. The Z-axis position sensor is disposed so as to be spaced from the second coil, and the detection magnet is disposed on a side opposite to a second driving magnet with respect to the Z-axis position sensor. The Z-axis position sensor detects a displacement amount V of the detection magnet in the Z axis direction.
