Abstract
An image reader feeds a document to read document information at a still position from below a glass platen. The image reader is configured to include a document feeder unit feeding a document in a predetermined direction, a glass platen provided below the document feeder unit, an illumination unit provided on or above the glass platen and including a surface light source which is long in a direction orthogonal to the predetermined direction and illuminates the document, and a document reader unit reading document information at a still position from below the glass platen. Such an image reader can illuminate documents efficiently with less electric power and achieve thinning of the illumination unit.
