PURPOSE:To obtain a photoscanner which has superior compatibility among units by arranging a specific mirror between an optical image forming system for scanning and a scanned medium and unitizing respective parts of the scanner. CONSTITUTION:Light projected from a light source 1 scans on the scanned body 7 through a linear-image forming system 2, polarizer 3, spherical single lens 4, single lens 5 with a toric surface, and mirror 6. The mirror 6 is adjusted independently around an axis 6a of rotation which crosses an optical axis in the mirror surface and is fixed in parallel to a main scanning direction and an axis 6b of rotation which crosses the axis 6a of rotation in the mirror surface and is fixed where it crosses the optical axis. The parallel shift component of a position shift of the main scanning line from a specific position is adjusted by rotation around the axis 6a of rotation and the inclination component is adjusted by rotation around the axis 6b of rotation. The part from the light source 1 to the mirror 6 is constituted in one body to obtain the superior compatibility. |
