PURPOSE:To attain an optional arrangement by coupling various processing sections with an optical fiber so as to transmit/receive an input/output signal being a processing object in a form of optical signal, thereby eliminating the need for the adjustment in an optical axis direction and spatial position between various processing elements. CONSTITUTION:The optical outputs from laser beam sources 21B, 21G, 21R are extracted through optical fibers 23B, 23G and 23R. Optical modulators 24B, 24G and 24R introduce a modulation signal from a computer 3 to modulate the input light and each output light is fetched as each input of an optical coupler 28 through optical fibers 27B, 27G, 27R and the combined optical output is led to an optical connector 30 through the optical fiber 29 and introduced to a lens 11. Thus, optional arrangement is applied to each processing section for its mounting position and direction so long as they are coupled with the optical fibers. |
