Abstract
In an image reading apparatus, three line sensors simultaneously read images in different positions of a document and output respective image signals. Line memories receive the image signals and output them with a timing corresponding to the positions in which the images represented by the image signals have been read. Analog signal processing for the image signals is executed in a parallel manner to thereby allow a high-speed image read operation to be achieved with a low-speed analog processing circuit.
