ABSTRACT:
The invention relates to an image reading apparatus for reading images of original documents by moving the original relative to a stationary image reader. A single image reader is used in a first embodiment. When reading the image of a first side, the single image reader is stationary at a first position to read the original. When reading the image of a second side, the single image reader is moved to a second position corresponding to the size of the original, and reads the image of the second side while said image reader is stationary at the second position. The image reading apparatus of the second embodiment uses a stationary first reader for reading a first side of an original, and movable second image reader for reading a second side of an original. The image reading apparatus of the second embodiment changes the positions of the image reader in accordance with the size of the original.
