PURPOSE:To attain ease of the entire adjustment by fixing incorporatedly a lens and a sensor and adjusting them to make the moving amount of the sensor corresponding to the moving amount of an original face without projection and shrinking. CONSTITUTION:Plural sensors 22A-22C reading information are provided to a reading element fitting and adjusting device, and a light separated for color is made incident to the sensors 22A-22C via lenses (optical system) 24A-24C. Sliders 120, 220 adjusting the relative position between the optical axis of the lenses 24A-24C and the center of the sensors 22A-22C in the fixed state are provided. Further, a frame body 122 as the 1st adjusting means where the sensors 22A, 22B and the optical system are turnable around the optical axis of the lenses 24A and 24B are provided to the sliders 120, 220. Moreover, the direction of the optical axis of the lenses 24A, 24B and the direction of a coordinate axis of the orthogonal coordinate system coincident with any of the said coordinate axes are adjusted by moving the sensors 22A, 22B and the lenses 24A, 24C by means of bearings 126, 128, 226 and 228 and guide axes 130, 230 being the 2nd adjusting means to make the entire adjustment easy. |
