Abstract
An image reading device is movable at a predetermined speed relative to a document in a lengthwise direction of the document so as to read a document image and includes a plurality of image sensors arranged in line in a widthwise direction of the document, each image sensor including an array of first to n-th photoelectric conversion elements arranged at the same interval in line, and scan means for causing the array of photoelectric conversion elements of the respective image sensors to scan in the order of first to n-th at a predetermined period. The array of photoelectric conversion elements of the respective image sensors is arranged in such a way that the first photoelectric conversion element slips relative to the n-th photoelectric conversion element a predetermined distance in the direction opposite to the relative movement direction of the image sensor, the predetermined distance being defined by the predetermined relative movement speed and the predetermined period.
