Abstract
A two-sided original reading apparatus includes carrying means for carrying an original in a predetermined carrying direction. First reading circuitry reads the image on the first face of the original at a first reading position and generates first analog image signals. Second reading circuitry reads the image from the second face of the original at a second reading position different from the first reading position with respect to the carrying direction, and generates second analog image signals. Converting circuitry converts the first and second analog signals into first and second digital signals, respectively. Delay circuitry is provided for delaying one of the first and second digital image signals with respect to the other by a delay time which corresponds to a deviation between the first and second reading positions.
