The second signal 030 is also a laser beam that moves linearly with energy being concentrated, as in the first signal 010. The first signal 010 and the second signal 030 are not overlapped and form an included angle, so that the signal receiver 400 at a different position from the signal transmitter 200 can receive the second signal 030, and when the signal receiver 400 can receive the second signal 030, it can be determined that the signal reflector 300 has moved to the predetermined position.
