<P>PROBLEM TO BE SOLVED: To provide an optical radio transmitter for easily directing the optical axis of an optical signal, whose outgoing angle is relatively narrow to be transmitted by a transmitter, and for assuring more stable data transmission path. <P>SOLUTION: A light transmitting unit is provided with a first light-transmitting means and a first light-receiving means for receiving the rays of light by a plurality of light-receiving elements; and the light-receiving unit is provided with a second light-transmitting means and a second light-receiving means for receiving an optical signal; and the light-transmitting unit moves the first light-receiving means to make uniform the light-receiving levels of the plurality of light-receiving elements, and matches the first optical axes of the first light-receiving means and the second light-transmitting means, and the light-transmitting means matches the optical axes of the first transmitting means and the second light-receiving means, based on the light-receiving status information from the second light-transmitting means, and the light-transmitting unit moves at least one of the first light-transmitting means and the first light-receiving means, based on the moving quantity and moving direction of the movement detecting means for calculating the moving quantity and moving direction according to the movement, and makes the the first and/second optical axes coincide. <P>COPYRIGHT: (C)2007,JPO&INPIT |
