| 英文摘要 | A light source unit of the present invention is provided with a plurality of semiconductor lasers each emitting one laser beam, a bar body to which the semiconductor lasers are attached so that p-n junctions planes of respective semiconductor lasers are arranged in the same direction, and a beam restricting plate where holes for passing a part of the beam from the semiconductor laser are formed so as to correspond to the semiconductor lasers. With this feature, a plurality of laser beams of uniform optical power can be emitted at predetermined spaces. |
