PURPOSE: To provide an optical spatial communication equipment for surely performing optical communication by maintaining alignment even while the sun is positioned within the image angle range of a position detector in the case of transmitting or receiving a modulated light beam between two pieces of optical spatial communication equipment by arranging them while facing each other with a space between. CONSTITUTION: Concerning the optical spatial communication equipment for performing communication by transmitting the light beam modulated by a prescribed signal to the side of a party or receiving the light beam from the party side, this equipment is provided with first detecting means 8 and 48 for detecting the position state of light while using a light receiving means for receiving light from the opposite side, second detecting means 47 for detecting the attitude of the optical spatial communication equipment itself, and adjusting means for adjusting the direction of the beam while selectively using signals from the first detecting means 8 and 48 and the second detecting means 47. |
