A correcting mechanism of an electronic azimuth meter includes a storing unit for storing maximum values and minimum values with regard to magnetic field detecting values by X- and Y-direction magnetic sensors, an updating unit for updating the magnetic field detecting values when newly detected magnetic field detecting values exceed maximum values / minimum values of the storing unit, an azimuth change inducing unit for providing display for inducing continuous change of azimuth of an electronic azimuth meter main body in a range larger than 360 degree, a predicting unit for predicting whether maximum value / minimum value are true when maximum/minimum magnetic field detecting values are not updated during a predetermined time period even by rotating the azimuth meter main body in accordance with induction display and canceling true prediction when maximum value / minimum value are updated and a stop control unit for stopping updating processing when all of maximum values / minimum values in X- and Y-directions are predicted to be true and induction by inducting display reaches 360 degree or more. <IMAGE> <IMAGE> |
