PROBLEM TO BE SOLVED: To provide an image reader which adopts an off-axial optical system and in which an imaging mirror and a CCD-mounting-position adjusting means are fixed by a highly rigid structure and since the relative position between reflecting mirrors and imaging mirrors can be set highly accurately, adjusting only the CCD-mounting position allows a required specification of the read image to be met and the imaging mirror can easily be adjusted without distorting the reflecting surface when necessary. SOLUTION: The reflecting mirrors, the imaging mirrors, and the CCD-mounting-position adjusting means are positioned directly to reflecting-mirror supporting sections, imaging-mirror supporting sections, and CCD supporting sections, which are integrated with a carriage casing, and fixed to them. The CCD is fixed to the carriage casing with the CCD-mounting-position adjusting means. An imaging mirror close to a diaphragm and adjacent to the image is supported by a mirror adjusting plate. The position of the imaging mirror is adjusted by displacing the mirror adjusting plate. COPYRIGHT: (C)2005,JPO&NCIPI |
