    Abstract: An image reading device, such as may be employed in a facsmile transmitter, laser beam printer, copying machine, or the like, in which assembly and alignment of optical components of the system is simplified and stray light is prevented from reaching a photoelectric conversion element. The optical system and the photoelectric conversion element are fixedly secured to a single supporting frame in a desired predetermined positional relationship. The supporting frame is detachably mounted on a mounting surface of an image reading device body. The optical system includes a filter or dust-proof transparent cover, an optical path changing mirror, and an image forming lens, all of which are secured to the supporting frame. A light-quantity-distribution correcting light-shielding plate may be provided in front of the image forming lens to provide an even distribution of image light on the photoelectric conversion element.
