摘要：
A positioning device comprising a moving portion provided with a pair of magnets arranged respectively along with a first axis and a second axis, a fixed portion provided to face to the moving portion, and a voice coil motor (VCM) for relatively driving the moving portion and the fixed portion by an electromagnetic action between a coil and a drive magnet provided to each of the moving portion and the fixed portion: wherein one of the magnets is arranged so as to reduce a rotation moment generated by an electromagnetic connection between the other magnet and the voice coil motor.
