<P>PROBLEM TO BE SOLVED: To provide an optical radio transmitting device and an optical axis adjusting method which enable to install a transmitting device and a receiving device oppositely with higher precision and more easily than before. <P>SOLUTION: In optical axis adjustment of the transmitting device 2 and the receiving device 3 of the optical radio transmitting device 1 which are installed oppositely, after a first optical axis adjustment including influence of reflected waves based on a wide directional pilot light d emitted from a wide directional pilot light emitting part 23 of the transmitting device 2, a movable transmitting part 10 of the transmitting device 2 is turned for scanning by emitting beam-like narrow directional burst pilot light b from a light emitting part for data transmission of the transmitting device 2. By controlling scanning to stop when a second four-split light receiving part 33 of the receiving device 3 receives the narrow directional burst pilot light b, optical axis adjustment eliminating the influence of the reflected waves included in the pilot light is made possible. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
