  • Publication number: 20080048809
    Abstract: When a magnetic substance (104) is brought close to or separated away from an MR sensor (102), so that a direction of a magnetic flux (103) caused to flow through the MR sensor (102) is changed, an output voltage from the MR sensor (102) changes. Also, when a change in output voltage from the MR sensor (102) exceeds a threshold set by a designer, a comparison portion (303) judges that switches (309a, 309b) should be turned ON, and outputs suitable signals to corresponding portions, respectively.
