PURPOSE: To detect the angle of inclination accurately by detecting the angular velocity of a main body in the direction for detecting the inclination angle, and correcting the detected inclination-angle information so as to compensate for the decrease in response characteristic on the high-region side of the angular velocity of an inclination-angle detecting means based on the detected information. CONSTITUTION: An angular velocity sensor 28 detects the angular velocity of a main body in the detecting direction of an inclination angle. The inclination sensor 20 requires the time in following the liquid in the inside when the change in inclination angle (angular velocity) is quick. Therefore, the detected inclination angle information, whose response characteristic on the high-region side of the angular velocity is decreased, is outputted. Therefore, the detected inclination angle information of the sensor 20 is corrected so as to compensate for the decrease in response characteristic at least on the high-region side of the angular velocity of the sensor 20 based on the information of the sensor 25, and the corrected detected inclination angle information is outputted. Thus, the accurate inclination angle information, wherein the decrease in response characteristic is corrected, is obtained. |
