ABSTRACT:
An image reading apparatus includes a photoelectric conversion unit which is held, together with a first movable optical reading unit and a second movable optical reading unit, on a guide member instead of a chassis. Since all of the first movable optical reading unit, second movable optical reading unit and photoelectric conversion unit are held on the common guide member, the positional relationship between the photoelectric conversion unit and the guide member is held always constant even when a chassis is deformed due to an environmental change or an external force. This arrangement insures a high image quality reading. The image reading apparatus also includes a transparent plate disposed on an upper surface of an original holding glass plate so as to cover a moving original reading position defined at that glass plate portion. An exit guide have a front end which is disposed adjacent to a downstream end of the transparent plate and held at a level below an upper surface of the transparent plate. With this arrangement, a moving original sheet can smoothly move from the transparent plate to the exit guide without being caught by the front end of the exit guide.
