ABSTRACT:
In carrying out location control of a control object by decelerating a driving source for the control object over a suitable number of stages, this invention is based on the conception that inertia and strain occur in the control object, the driving source keeping such output as to allow a uniform motion of the control object and transmission mechanisms connecting them due to the uniform motion of the control object in a preceeding stage, and they exert significant influences over the location accuracy of the control object and wearing of the machine. In the present invention, therefore, the driving source of the control object is brought under deceleration control at such a timing where the strain occurring in the control object and its associated mechanisms becomes minimum.
