PROBLEM TO BE SOLVED: To provide a constituent part which performs bidirectional optical data transmission without being restricted by power, which can utilize large optical transmission and reception output. SOLUTION: A constituent part 1, which performs orientated bidirectional optical data transmission without being restricted by power, is decided to be attached to the hem of a printed board 10, and it consists of a well-known housing 2 for an integrated circuit equipped with a connection leg piece 9, and in this housing, two lenses 3 and 4 for optically amplifying the IR beam transmitted from an emitter chip and received with a detector chip are made integrally. At that time, the diameters of the lenses 3 and 4 are larger than the thickness of the housing 2 for the integrated circuit, therefore the lenses 3 and 4 are projected downward over the mounting plane 1 made of the connection leg piece 9. |
