Abstract
A surveying machine that automatically adjusts an optical axis includes a sighting optical system for sighting an object, a light-transmitting optical system that transmits a beam for surveying, radiated from a light source, to the object, a deviation detector, and an optical axis adjuster. The deviation detector detects a deviation between a first optical axis corresponding to the sighting optical system and a second optical axis corresponding to the light-transmitting optical system. The optical axis adjuster automatically adjusts at least one of the first optical axis and the second optical axis so as to correct the deviation.
