Abstract

PURPOSE:To facilitate multichannel connection by arranging a couple of rotatable bodies which have center shafts as a common rotating shaft, and performing light-to-light direct coupling between the rotatable body and an unrotatable body, etc. CONSTITUTION:Light when incident to the end surface of a photoconductor 4 fitted to one rotatable body 1 is led out through an annular photoconductive exposed surface 41, the surface 41 of the other rotatable body 1, and the photoconductor 4. Then, a flange 5 fitted to one rotatable body 1 is aligned to the rotating shaft of a rotary drum D, and a flange 5 fitted to the other rotatable body 1 is fixed to the base of the drum D; and optical transmission fibers forming an optical transmission line C wound inside the drum D are each connected to the other end part of one of photoconductors 4 of one rotatable body 1, and optical transmission fibers forming an optical transmission line C' is each corrected to the other end part of one of photoconductor 4 of the other rotatable body 1. Thus, the optical transmission fibers of a rotating optical transmission C are coupled optically with those of a still optical transmission line C' in 1:1 proportion.
