PURPOSE:To provide an accurate stable servo controller, which uses two detecting means with different accuracy. CONSTITUTION:A first detecting means 7 which is coupled with a rotating body 6, and divides overall movable range of the rotating body into plural rotation ranges and detects one rotation range from the divided rotation ranges, and a second detecting means 9 which is coupled with the first detecting means, and rotates a plurality of times while the first detecting means makes one revolution to detect an absolute value of revolutions, are provided. Consequently, the rotation body is controlled with output signals from the first and second detecting means. |
