読取装置。[Scope of Claim for Utility Model Registration] A reading means for optically reading information by receiving reflected light from a document, a feeding mechanism for conveying the document to the reading means, and a document detection device for detecting the document being conveyed by the feeding mechanism. In the optical information reading device, the original detecting means includes a light receiving element disposed at a position capable of receiving a part of the illumination light from the original illumination light source forming the reading means. An optical information reading device characterized in that it is configured to detect a document being transported based on a change in the amount of light input to a light receiving element.
