Claims

[Scope of claims for utility model registration] (1) A light source holder with a light source attached to the center,
A cylindrical lens barrel incorporating an optical lens,
A light source device comprising: a lens barrel holder that accommodates the lens barrel so that its position can be adjusted and moved in the optical axis direction of the light source; and a set screw that fixes the lens barrel to the lens barrel holder, A recess is formed in the outer peripheral surface of the lens barrel, and an elastic member is provided in the recess, and the elastic member biases the lens barrel in one direction on the inner peripheral surface of the lens barrel holder. A light source device characterized in that the lens barrel is pushed toward the lens barrel holder by the set screw in the same direction as the biasing direction. (2) A light source holder with a light source attached to the center,
A cylindrical lens barrel incorporating an optical lens,
A light source device comprising: a lens barrel holder for accommodating the lens barrel so that its position can be adjusted and moved in the optical axis direction of the light source; and a fixing means for fixing the lens barrel to the lens barrel holder. , a convex portion is formed on the inner circumferential surface of the lens barrel holder at a portion closer to the light source, and the convex portion is fixed at a position equidistant from the optical axis of the light source on a surface opposite to the light source side. fixing an elastic member, forming a slope on the lens barrel that comes into contact with the elastic member, and fixing the lens barrel with the convex portion by pressing the lens barrel in the optical axis direction with the fixing means. Characteristic light source device.
