Abstract:
1. An image scanning device capable of performing one-side scanning and double-side scanning operations, comprising: a first sensor that scans an image formed on a first surface of a sheet, said first sensor reading the image and outputting an image signal representing at least one color component of the image; a second sensor that scans an image formed on a second surface of the sheet, said second sensor reading the image and outputting image signals representing a plurality of color components of the image; a plurality of image processing systems that process the signals representing the plurality of color components of the image, respectively; a switching system that is controlled to selectively connects an input terminal of a predetermined one of said plurality of image processing systems with an output terminal of said first sensor and a predetermined output terminal of said second sensor, said predetermined output terminal of said second sensor outputting a predetermined one of said plurality of color components; and a controller that controls said switching system to connect the input terminal of said predetermined one of said plurality of image processing systems with the output terminal of said first sensor when the double-side scanning operation is performed, a signal output from one of output terminals of said second sensor other than said predetermined output terminal being used as an image signal representing the image of the second surface of the sheet when the double-side scanning operation is performed.
