Abstract

PURPOSE:To eliminate a light source light quantity control device and to simplify the constitution of an image reading device by inserting an extinction means into a reading optical path and reducing light quantity to a solid-state image pickup element. CONSTITUTION:A microfilm 5 is irradiated by the light of a light source with an exposure lamp 2 and a transmitted light, which is enlarged by a projecting lens 7, is enlarging-projected through a projecting optical path X on a screen 11. On the other hand, the reading optical path is formed at a reading mode time and the enlarged transmitted light is incoming to a solid-state image pickup element 14 of a CCD. Then, the film 5 is read. An extinction means 23 is provided in this reading optical path and the incoming light quantity to the element 14 is reduced. Then, the light source light quantity control device, which controls a voltage, etc., and changes the light quantity of the lamp 2, is eliminated and the constitution of the image reading device of the microfilm is simplified.
