Abstract

PURPOSE:To prevent the induction of reflected light from a 1st mirror, which scans an original, onto an image forming lens on a light shielding member and to improve the effect of light shielding by providing the light shielding member having a specified angle with respect to said reflected light above the image-forming lens. CONSTITUTION:The tilt of the slope of a chevron part 8a is set so that the harmful oblique luminous flux D from the 1st mirror (4) is not made incident on a 2nd mirror 5 side even if said flux D from the 1st mirror 4 is reflected on the slope of the chevron part 8a formed on the light shielding member 8 for a lens when the 1st mirror 4 which scans the original 1 is positioned in the vicinity of the end part B above said member 8. With such a constitution, the harmful oblique luminous flux D from the 1st mirror 4 can be prevented from made incident on the image-forming lens 7 through the 2nd and a 3rd mirrors 5 and 6 even if the 1st mirror 4 is positioned in any position between the position B and a position C.
