ABSTRACT:
An image reader includes a fight source projecting a light onto an original, and first and second photoelectric conversion elements arranged so that the first photoelectric conversion element reads first half of the original in a scanning direction and the second photoelectric conversion element reads the second half and that a first read signal of the first half of the original is transferred, starting from a center of the original, from the first photoelectric conversion element and a second read signal of the second half of the original is transferred, starting from the center, from the second photoelectric conversion element. An imaging lens projects a reflected light reflected by the original onto the two photoelectric conversion elements. A driver circuit drives the first and second photoelectric conversion elements so that the first and second read signals are output from the first and second photoelectric conversion elements, respectively. A signal processing unit processes the first and second read signals so that a finalized read signal containing information on pixels arranged in the scanning line is generated each time the original is scanned in the scanning direction.
