Steuervorrichtung für bewegbares Teil

摘要

A control device (1) for a movable member includes a dc motor (11) for establishing position transfer of the movable member in such a manner that after a first position of the movable member is stored in a memory, even if the movable member is at a second position, the moving member is returned to the first position only upon manipulating a switch (8); and a motor pulse generating circuit (3) generating a cut-off frequency which is variable depending on a ripple pulse frequency which is indicative of a rotational number of the motor.
