ABSTRACT:
A measuring head is provided with a retracting device for a sensing pin, comprising an electric motor-driven feed screw, a nut shifted by the feed screw and an inclined face formed on the nut; a seesaw member to which the sensing pin is fitted is swung by the linear motion of the inclined face to retract the sensing pin; not only can the retracting speed and the returning speed of the sensing pin be controlled as desired but also can the retracting action of the sensing pin be stopped on the way to make possible its fine positioning. Further, the electric motor may be provided with a manual knob, and the sensing pin would be thereby enabled to be manually retracted.
