Abstract: PURPOSE:To easily attain the optical transmission bisectionally through one optical fiber by using an optical fiber for transmission serving also as reception in common and setting a transmission optical line and a reception optical line in different directions within an aperture angle of the optical fiber for transmission serving also as reception. CONSTITUTION:A light from a light emitting element 11 is collected by a condenser lens 14 on a transmission optical line A. A transmission reflection mirror surface 16 is irradiated with the light and the incident light is reflected in the transmission reflection mirror surface 16 and led to the transmission serving also as reception optical fiber 13. On the other hand, the reception reflecting mirror surface 17 on a reception optical path B is irradiated with the light from the transmission serving also as reception optical fiber 13 and the light is reflected with the reception reflecting mirror surface 17, the reflected light is collected by a condenser lens 15 and received by a light receiving element 12. That is, the transmission serving also as reception optical fiber 13 is used to set the transmission optical path A and the reception optical path B respectively in different directions within an aperture angle. Thus, the optical transmission bidirectionally is attained easily through one optical fiber.
