When light other than guide light is searched by error, the collimation direction of a surveying instrument is changed by emitting a continuous-operation command from the side of a target toward the surveying instrument, and a process for searching proper guide light can be restarted. When a direction detector receives disturbing light differing from guide light in the process of searching the guide light emitted from a guide light transmitter of a target by means of a surveying instrument, a continuous-operation command is emitted from the target toward the surveying instrument. Accordingly, the light receiving direction of the direction detector is changed by driving an instrument body, and a horizontal or vertical rotation is made to a position deviating from a light receiving range obtained when the direction detector receives the disturbing light, and thereafter the process of searching the guide light is restarted.
