おいて、光源からの光を原稿に反射させてから上
記結像光学系に導く光路の他に、光源からの光を
対反射板を介して原稿にあてその反対光を上記上
記結像光学系に導く光路を設定するとともに、該
結像光学系と光源との間に格子状スリツトを有す
る遮光板を設けたことを特徴とする光学装置。 In an imaging optical system using a roof mirror lens array, in addition to an optical path in which light from a light source is reflected onto an original and guided to the imaging optical system, the light from the light source is also directed onto the original through a counter-reflector. An optical device characterized in that an optical path is set for guiding the opposite light to the imaging optical system, and a light shielding plate having a grid-like slit is provided between the imaging optical system and the light source.
