Abstract

PURPOSE:To make the device simple by disposing a plurality of secondary optical transmission wires by way of a convex lens in the positions opposing to a primary optical transmission wire, parallel-sliding the primary exit light axis with respect to the central axis of the lens and rotating this light axis as the axis of rotation of the lens. CONSTITUTION:Plural secondary side optical transmission wires 12-15 are disposed by way of a convex lens 16 in the positions opposing to a primary side optical transmission wire 11, on the same circumference with the optical axis B of the transmission wire 11 as a center. The primary side optical transmission wire 11 is disposed in the position where its exit light axis B is deviated by a desired size in parallel with the central axis A of the convex lens 16, in such a manner as to permit the controlling of its rotation angle with its exit light axis B as the axis of rotation of the convex lens 16. Such constitution makes it possible to readily switch the transmission optical path selectively by rotating the convex lens 16 thereby so angle- controlling the incident light axis as to be aligned to the incident end of the desired transmission wire out of the plural secondary side optical transmission wires 12-15.
