PURPOSE:To make the setting adjustment of optical transmission wires and optical system easy and make construction simple by reflecting and entering the exit light from a primary side optical transmissin wire to the incident end face of the secondary side optical transmission wires disposed on the same plane side with a plano- convex lens as a reflecting mirror. CONSTITUTION:Plural secondary side optical transmission wires 5-8 are disposed on the same circumference with a primary side optical transmission wire 1 as a center. In opposition to the end face of each optical transmission wire, the plano- convex lens 101 integrating a lens and a photo switching reflecting mirror is provided. the rear face of this lens 101 is made to a reflecting face 102 which is inclined by the specified angle theta and is connected to a rotation driving part 9 by way of a stationary block 104. Here these are so arranged that the axis of rotation of the stationary block 104 and the exit light axis from the primary optical transmission wire 1 align. Hence, the exit light from the primary side optical transmission wire 1 may be selectively entered and switched to the secondary side optical transmission wires 5-8 according to the angle of rotation of the plano-convex lens 101 on its optical axis. |
