PROBLEM TO BE SOLVED: To provide an image-reading apparatus for improving picture quality due to intermittent reading when reading a single-sided manuscript by effectively utilizing the processing and storage means of image information in the image- reading apparatus that can read a double-sided manuscript. SOLUTION: The image-reading apparatus comprises a first reading means for reading image information on the first surface of a manuscript to be carried by a manuscript-carrying means, a first image-processing means for processing output data from the first reading means, a second reading means for reading image information in a second surface that differs from the first surface of the manuscript to be carried by the manuscript-carrying means, a second image- processing means for processing output data from the first reading means and output data from the second reading means, a switching means for switching whether output data from the first reading means are inputted to the first image-processing means or are inputted in parallel to the first and second image- processing means, and a means for turning on or off an input path for inputting output data from the second reading means to the second image-processing means.
