PROBLEM TO BE SOLVED: To provide an angle detection device for detecting an inclination angle of an object to be measured with respect to a horizontal plane with a new configuration.SOLUTION: The center of gravity G of the horizontal axis rotator 11 is located in a vertically lower side of the rotating shaft, and even if the inclination angle of a case member 10 with respect to the horizontal plane changes, the posture does not change since the center of gravity is at a position different from a position of the rotating shaft. An imaging sensor 12 is fixed to the case member 10, and when the inclination angle of the case member 10 with respect to the horizontal plane changes, the imaging sensor 12 is inclined together with the case member 10 while being kept opposed to the outer circumferential surface s. Thus, if the outer circumferential surface s is viewed from the imaging sensor 12 toward the rotation axis 11a, an intersection position between a diagonal line d and an imaging element group shifts along the array direction of a plurality of imaging elements. Thus, an output result of the imaging sensor 12 becomes different according to the inclination angle of the case member 10 with respect to the horizontal plane, and the inclination angle of the case member 10 with respect to the horizontal plane can be detected. |
