Summary:PROBLEM TO BE SOLVED: To align optical axes in a short time with loose accuracy in the range finding by retrieval of opposite devices in the case of installation of the receivers. SOLUTION: A deviation width from a transmission beam optical axis is set to be O-R1 in the case of an intensity P1 of a transmission beam that provides a light receiving amount of a limit of detection in optical axis deviation in a conventional embodiment. The receiver can detect the optical axis deviation up to a point R2 at which an intensity P2 of a transmission beam is about 10% of the intensity P1, and then the permissible deviation width is 0 to R2 so as to widen the width more than the conventional embodiment. Thus, the optical axes of the receivers are aligned with a looser accuracy than that of the conventional embodiment quickly by using the receivers.
