CONSTITUTION: A plurality of actuators are formed in a predetermined interval along a shaft of a rotary body. The actuators are controlled by predetermined signals. A sensing portion is located at a position apart from the rotary body in order to sense the vertical displacement of the rotary body. The sensing portion is formed with plural sensors. A non-collocation compensation portion receives an output of a sensing portion, generates a predetermined compensation signal for controlling an actuator, and outputs the compensation signal to an actuator control portion. The actuator control portion controls the actuator. The non-collocation compensation portion is formed with the first amplifier(42), the second amplifier(44), and an adder(46) for adding an output of the second amplifier(44) to an output of the first amplifier(42).
