ABSTRACT:
A moving member mechanism includes an electromagnet having a coil for driving a moving member, a first control mechanism which has an input portion which receives command information and an amplifier which supplies a current to the coil, and an offset compensation mechanism which includes a first integrator which time-integrates a signal at an input portion of the amplifier. The offset compensation mechanism is configured to negatively feed back an output from the first integrator to the input portion of the first control mechanism.
