ことを特徴とする画像読取装置。[Scope of Claim for Utility Model Registration] In an image reading device in which a document is illuminated by a light emitting element and reflected light from the document is imaged on an image sensor by a converging light transmitter array, the reading section has a reflectance. An image reading device characterized in that a filter is selectively provided that is transparent to a document with a high degree of light and causes diffused reflection.
