Ball screw is often used as the mechanism which changes rotary motion into the linear motion. In case of this mechanism, the overrun of the nut occur destruction for the ball screw at the stroke end. It has a purpose of the development of the detector which makes the position of the end. The watching recognition for the end is possible in the case of which is difficult to set limit switches on the prolongation or the parallel line of the ball screw. This form is comb wheel of the magnetism which the n, n+1 number of the combs. And it uses photoelectric for the detection. The turn mechanism, there are two comb wheels has marks each other. When n comb wheel is turned in "n+1", the others turn in "n" and the marks correspond. If optional points exist within "n+1" turn in n comb wheel, it is possible to detect optional points in addition. It developed "The Magnetism Comb wheel" that is magnetism turning for this purpose. As for the detection, it detected using some light sensors at top surfaces of comb wheels. Also, it reports on these theories.
