A surveying instrument (1) has a measuring unit (25) and comprises an operation control panel (4) mounted on the measuring unit to rotate about a vertical axis with respect to the measuring unit, and a relative angle detecting means (7) for detecting the relative angle of the operation control panel (4) and the measuring unit. The operation control panel (4) is arranged to issue a command to rotate the measuring unit based on the angle detected by the relative angle detecting means (7). |
