Abstract

An image reading device includes a transporter transporting a document to a reading position, a first corrector correcting a skew of the document by coming into contact with a leading edge thereof, a radiating unit radiating light to the document, an image-information acquiring unit acquiring image information of the document based on information of light reflected therefrom, a reflector reflecting the radiated light, a leading-edge detector comparing a quantity of light reflected by the reflector with a quantity of light reflected by the document so as to detect the leading edge, a skew-amount calculator calculating a skew amount of the leading edge, and a second corrector correcting a skew of the image information based on the skew amount. The device switches between the skew correction by the first corrector and the skew correction by the second corrector based on document information, the skew amount, or user's selection.
