<p><P>PROBLEM TO BE SOLVED: To reduce errors of indication of an azimuth sensor by suppressing magnetic fields generated by electric currents inside a mobile device and keeping an earth magnetism sensor from sensing them. <P>SOLUTION: When one of current conductors 13, an outward conductor 13a or a return conductor 13b is divided into two, and the other current conductor 13 is arranged to be sandwiched between the ones divided into the two, the magnetic fields generated by the electric currents of the outward conductor 13a and return conductor 13b are canceled each other out, and a component generated as a noise magnetic field is reduced. The noise magnetic field component generated is reduced not only at a point right above the center part of the wiring of the outward conductor 13a and return conductor 13b but at a horizontally spaced point, and the restriction on the placement of a magnetic sensor 11 is diminished. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
