<p>PROBLEM TO BE SOLVED: To obtain a laser bar holding device which holds a plurality of laser bars by simultaneously exposing the light-emitting side faces and light-reflecting side faces of the bars. SOLUTION: Spacers 21-29 are installed across a groove provided in a holding frame 1, and the laser bars 11-18 are arranged among the spacers 21-29 and fixed, by pressing the bars 11-18 by means of a sliding section 3 and a shaft 2. The longitudinal lengths of the spacers 21-29 are made longer than those of the laser bars 11-18, and the bars 11-18 are installed in a state where the bars 11-18 are separated from the holding frame 1 by >=3 mm.</p> |
