PURPOSE:To prevent partial duplicate reading, missing of reading, and shift of picture, by taking an image forming optical system to a primary dimension image sensor as one common system and providing an optical path split mirror surface at the light emitting side of the system. CONSTITUTION:A picture of an original 1 of an original stand is formed on the 1st and 2nd primary image sensors CCDs 1, 2 with a common image forming optical system 7. A light through a part corresponding to the 1st half A of the information along the main scanning direction of the original 1 is directly irradiated and formed on the 1st sensor CCD1 out of lights through the system 7. Further, a light of a part corresponding to the latter half B of the information is emitted from the system 7 and split and deflected from the light corresponding to the 1st half A of information on an optical path split mirror surface 8 and formed on the 2nd sensor CCD2. Thus, a part of the original can never be read with two lenses or lost. |
