Abstract
An image reading device includes a control unit for controlling an image reading unit so as to perform a reading operation within a range obtained by adding predetermined widths m and n to a reading range set after prescanning by a setting unit so that the relationship of X X m and Y Y n holds at main scanning, where m and n are constants, X and Y are the lengths of the set reading range in the x-axis and y-axis directions, and X and Y are the lengths of an actual reading range in the x-axis and y-axis directions, respectively. As a result, it is unnecessary to perform troublesome operations, such as reassigning a reading range, and again performing a reading operation.
