<p><P>PROBLEM TO BE SOLVED: To avoid transmission failure of light signals in bidirectional reception and transmission of signals, and to obtain an optical slip ring having improved productivity. <P>SOLUTION: The optical slip ring 10 for transmitting and receiving bidirectional light signals over a fixed member 2 and a rotary member 3, that shares an axis with the fixed member and is provided rotatably about the common axis A are presupposed. A first light receiver 6 is mounted to one member 2 in both members 3, 4, while being positioned on the common axis A. A second light transmitter 13, for transmitting the digital data of light signals reaching the optical receiver 6, is deflected from the common axis A and is mounted to the other member 3 in both the members, thus forming a first optical transmission/reception system. A second optical receiver 13 is mounted to the other member 3, while being positioned on the common axis A, a first optical receiver 7 for transmitting the digital data of light signals reaching the optical receiver 13 is deflected from the common axis A and is mounted to one member 2, thus forming a second optical transmission/reception system. <P>COPYRIGHT: (C)2004,JPO</p> |
