Abstract
An image reading apparatus includes an image reading portion, a rotation processing portion, a recognition processing portion and an inclination detecting portion. The image reading portion reads an image of a sheet conveyed through a conveyance path. The rotation processing portion applies rotation processing to the image of the sheet read by the image reading portion to generate a plurality of comparative images each having a different angle with respect to the conveyance direction of the sheet. The recognition processing portion applies recognition processing to a symbol of each of the plurality of comparative images to determine a corresponding matching degree. The inclination detecting portion detects the inclination of the image of the sheet based on the matching degrees.
