Abstract

PURPOSE:To obtain the image forming with fidelity, by tilting the reflection mirror with the tilt angle a half the tilt angle of the scanning body, in the scanner scanning with the scanning mirror through the transparent mirror and reflecting the image light downward with right angle. CONSTITUTION:The light radiated from the illumination soruce is radiated on the original 1b through the transparent glass 3 and the image is formed on the photosensing detector 10 via the scanning mirror 5, reflection mirror 6, moving mirrors 7, 8, and lens 9. When the original is a thick book 1b, the transparent glass 3 is tilted by angle alpha. In this case, when the reflection mirror 6 is tilted by alpha/2, the reflection light of the scanning mirror 5 is correctly image-formed on the photosensing detector 10.
