PURPOSE: To form optical transmission and reception equipment for multi-line two-way spatial transmission in a limited space by arranging a couple of transmitter and receiver bodies, having plural pairs of optical elements for transmission and optical elements for reception arranged opposite each other, opposite symmetrically about an axis. CONSTITUTION: An optical transmitter/receiver body 1 is equipped with plural pair of optical elements 2a for transmission/optical elements 3a for reception, which are arranged in a easing on right and left symmetrical sides. Then a couple of optical transmitter and receiver bodies 1 are prepared and arranged opposite each other symmetrically about the axis to form the optical transmission and reception device having a multi-line optical spatial transmission line. Consequently, the two-way optical transmission/reception reception device for plural lines can be formed in the limited space extremely easily and the opposition state of the optical elements for transmission/optical elements for reception for the respective lines can easily be obtained. |
