Abstract

PURPOSE:To make the device simple, inexpensive and minuature without using any reflecting mirror by deviating the central axis of two planoconvex lenses by a desired size and bonding these mutually at their plane parts to integrate them in changing over transmission optical paths. CONSTITUTION:In the position opposing to the primary side optical transmission wire 101 are disposed the plural secondary side optical transmission wires 102, 103, 104, 105 on the concentrical circumference centering at the exit optical axis A, by way of the optical path change-over means 106 which combines two planoconvex lenses 107 and 108. The optical path changing-over is accomplished by moving the central axis b of the lens 108 in parallel to the central axis a of the first lens 107. A beam is made to parallel beams by the convex face 109 and the parallel beams are sent to the convex face 110, where the change-over means 106 is rotated about the axis a, by which the beams are entered to, e.g., the optical transmission wire 102. In this way, the selective changing-over of the transmission optical paths is made possible by the rotation of the change-over means 106 and the movement of the lens 108.
