<P>PROBLEM TO BE SOLVED: To provide an optical signal transmission apparatus whose communication area in which transmission and reception can be performed has a sufficient wide range by deflecting an optical signal to be transmitted and sufficiently widening a deflectable angle range in a deflecting means on which a received optical signal is made incident, in an optical signal transmission apparatus for performing data transmission by transmitting an optical signal modulated on the basis of a data signal and receiving and demodulating an optical signal modulated on the basis of the data signal. <P>SOLUTION: The optical signal transmission apparatus is provided with: a first deflecting means 4 on which an optical signal emitted from a light emitting element 1 is made incident and which deflects the optical signal and transmits the optical signal to another optical signal transmission apparatus; a light receiving element 6 for receiving an optical signal transmitted from the other optical signal transmission apparatus through the first deflecting means 4; and second deflecting means 16A and 16B which turns the light emitting element 1, the light receiving element 6 and the first deflecting means 4 while maintaining their positional relationship, wherein the first deflecting means 4 has responsiveness higher than the second deflecting means 16A and 16B. <P>COPYRIGHT: (C)2007,JPO&INPIT |
