A high speed actuator consisting of coil springs with iron layers have been presented, in which displacements of the ends of actuators are controlled by electro magnets. Using the actuators, two dimensional positional control mechanism is presented, that controls the position of the instruction point on the screen by changing the angle of the laser pointer The mechanism consists of two spring actuators as just mentioned, in which one actuator is parallel to X axis and the other to Y axis, sliders, and a laser pointer. The laser pointer is rotated by displacing the springs. The displacement of the direction of X has no dependence on the direction of Y. Therefore, the instruction point can be scanned all over the range by operating the one actuator with high frequency and the other with low frequency. Moreover, the instruction point displaces to the target point by using usual PID control method.
