A control system for driving a rotary shaft and for positioning the shaft at a commanded position with one motor and two rotation transmission mechanisms of different ratios provided between the motor and the rotary shaft. The two transmission mechanisms are adapted to be selectively actuated to transmit the rotation of the motor to the rotary shaft. The rotary shaft is positioned at a commanded position using a feedback signal from a rotational position detector irrespective of which one of the two transmission mechanisms is employed. |
