  • Stroke sensor
    Patent number: 8570051
    Abstract: A stroke sensor includes conductor pieces 51 to 57 of a detected body 50 two-dimensionally arranged on a lower surface of a slider 41 in a specified pattern. The lower surface of the slider 41 is divided into four regions corresponding to respective detector units 61 to 64 along a Y-direction. The conductor pieces 51 to 57 are arranged over a specified X-direction extent in the respective regions. The arrangement of the conductor pieces 51 to 57 is set such that the combinations of the conductor pieces 51 to 57 detected by the detector units 60 become different in each and every shift range in the X-direction. This makes it possible to consistently specify the shift range based on the combination of the detector units 61 to 64 staying in the detected state.
