PROBLEM TO BE SOLVED: To reduce the moving time of a moving means in a low-cost constitution without increasing the size of the motor operated actuator. SOLUTION: An acceleration of the motor operated actuator 20 to a desired speed from speed-acceleration characteristics intrinsic for a motor 2 in the motor operated actuator 20 is set to the values A, B and C, and which are input to an acceleration selector 60. Speed commands A2, B2 and C2 sequentially calculated by a first integrator 62 from acceleration commands A1, B1 and C1 based on these set values A, B and C are compared with the change of the speed of the motor 2. When the speed of the motor 2 reaches the A2, B2 or C2, the motor 2 is controlled while the acceleration is changed to the corresponding acceleration commands A1, B1 or C1, and the accelerating operation and the decelerating operation of the slider 4 are performed.
