PURPOSE: To provide a light source device whose assembling/disassembling is simplified. CONSTITUTION: A mirror barrel 3 holds a printed circuit board 1a whose one end is mounted with a semiconductor laser and its drive circuit and a lens holder 2a incorporated with a collimeter lens is mounted to the other end. A couple of anunlar seat faces 4a, 4b are provided on the cylindrical face of the mirror barrel 3 and highly accurate finish is applied coaxially to a center axis of the mirror barrel 3. The seat faces 4a, 4b of the mirror barrel 3 are in press contact with circular-arc press contact faces 5c, 5d of support members 5a, 5b of a support 5 integral with a case H1 and an elastic member 6 energizes the mirror barrel 3 to the support 5. |
