Abstract

PURPOSE:To enhance the precision and to reduce the cost, by making the light from optical fibers into a parallel light flux by spherical lenses and by switching the light path of this light flux by rotaing the block such as a parallelepiped. CONSTITUTION:In light terminal blocks 27-30, capillaries 19-22 which consist of crustaceous materials such as ceramic and have minute holes of very little eccentricity are arranged, and transparent spherical lenses 23-26 with the surface subjected to no-reflection coating are arranged. Strands 15-18 of optical fibers 11-14 are inserted and fixed into these minute holes. If two light terminals obtained in this manney are caused to face to each other and block 31 such as a parallelepiped which consists of optical glass or the like and has the surface subjected to noreflection coating can be rotated to positions shown by the soild line and the one-dot broken line between these two light terminals, the parallel light flux from spherical lenses 23 and 24 has the light path switched in accordance with the rotation of this block 31.
