<P>PROBLEM TO BE SOLVED: To provide an optically coupled device which meets an explosion-proof requirement although the device is easily constructed at a low price and is easily mounted. <P>SOLUTION: In the optically coupled device, an optical transmission diode and a light receiving diode are disposed with a space on a conductive plate, and a plastic body or a glass body is disposed similarly on the conductive plate as an optical waveguide. <P>COPYRIGHT: (C)2004,JPO |
