Abstract
PURPOSE: To improve the precision of machine with ease further at low price, by quantitatively measuring an extending length of the belt and by additionally outputting the extending length of the belt as a correction quantity for every command signal when outputted.
CONSTITUTION: In the case with the invention applied to an automatic drawing instrument, at the time of power closing to actuate a movable unit mounted to an aluminum belt 11, that is, a figure construction head 12 in the lengthwise direction of a construction range 30, each of detecting values from a position detector 4 installed to a motor 3 and from a position detector 14 installed to the machine side is inputted to an arithmetic unit 8 with a position error processed an operation and stored in a memory unit 9. And the position error in the memory unit 9 is inputted to a correction circuit 10 as a construction start operates, with a quantity of the position error corrected for a detected value from the position detector 4, and inputted to a shifting quantity decision circuit 6, and on the basis of this output is made driven and controlled the motor 3 through a motor drive circuit 7.
