Abstract
The present invention relates to an image reading apparatus comprising an original document conveying route, original document conveying mechanism for conveying original documents along the original document conveying route, first reading unit for reading an image on one side of the original document; and second reading unit for reading an image on the other side of the original document. The first reading unit reads an image on one side of the original document while the original document is conveyed in a forward direction at a first speed by the original document conveying mechanism, and then after the original document is conveyed in a reverse direction at a second speed, the second reading unit reads the other side of the original document while the original document is again conveyed in the forward direction. The second speed is faster than the first speed.
