Abstract
An image reading apparatus includes a first illumination section configured to obliquely illuminate a surface of a sheet in an image reading area, a second illumination section arranged upstream of the first image reading area and configured to obliquely illuminate the surface of the sheet in the image reading area, and a reading section configured to read the surface of the sheet illuminated in the image reading area. The apparatus can switch between a two-side illumination mode in which the image reading area is illuminated by both illumination sections, and a single-side illumination mode in which the image reading area is illuminated by only one illumination section. The apparatus further includes a determination section configured to determine the state of the surface of the sheet (e.g., rip or creases) based on image data corresponding to the surface read in the single-side illumination mode.
