PURPOSE:To eliminate a variation of the light quantity caused by detaching and attaching an optical fiber connector, by optically coupling an optical element and an optical fiber for transmission, molding as one body that which has soldered a lead of the optical element to a pin of an electrical connector plug, and connecting it to an optical element use power source and a processor by an electrical connector. CONSTITUTION:As for an adhesion of a light emitting element and a projection use optical fiber 5, the light emitting element 2 and an optical feedback use light receiving element 3, and a signal use light receiving element 4 and a light receiving use optical fiber 6, an adhesive agent whose light transmissivity is high is used, and leads of the light emitting element 2 and the optical feedback use light receiving element 3 and the signal use light receiving element 4 are soldered to pins of an electrical connector plug 7, and the whole is molded by an epoxy resin adhesive agent or a silicone adhesive agent having an insulation characteristic. In this state, the optical element 2 is connected to a power source and a processor 10 by inserting the electrical connector plug 7 into a receptacle 9. Since the connection is not executed by an optical connector, a variation of the light quantity does not occur. |
