| 主权项 | 1. A simplified distance meter, comprising a frame, at least two wheels installed in front and rear of said frame, rotation detectors for detecting rotation of at least one wheel of said two wheels, and tilt detecting means installed on said frame, wherein amount of rotations of said at least one wheel is obtained by said rotation detector, and tilting of said frame corresponding to said amount of rotations is acquired by said tilt detecting means, and wherein said tilt detecting means comprises two tilt sensors, and is configured such that one of the two tilt sensors detects absolute horizontality, and the other has higher responding speed than said one tilt sensor, is capable of detecting tilting in wide range and detects deviation from the absolute horizontality detected by said one tilt sensor. | ||
