Claims

[Claims for Utility Model Registration] A light source section, a first imaging optical system that forms a linear image of the light beam generated from the light source section, and a light source in the vicinity of the imaging light produced by the first imaging optical system. A scanning optical system including a deflector having a deflection reflecting surface and a second imaging optical system that forms an image of the light beam deflected by the deflector onto a scanned medium, the first imaging optical system being supported. , comprising a plate spring attached to the lens holder so as to be freely rotatable and tiltable within a plane perpendicular to the optical axis, and a guide positioning means for freely adjusting the movement of the lens holder in the direction of the optical axis. Scanning optics.
