Abstract
An image reader includes a transparent plate (1) having end portions (1a and 1b) that are chamfered in a direction in which a document is carried thereon. The transparent plate (1) has recess portions (11aand 11b) formed in a lower surface thereof, and a housing (4) is engaged into the recess portions of the transparent plate. The image reader can prevent such a document as a check or banknote from being jammed, can be easily assembled and improve the reliability of the carrying of the document, and enables higher-speed reading.
