ことを特徴とする原稿読み取り装置。 a light source on a single rod; a one-dimensional image sensor that scans and reads a document irradiated by the light source; a mirror that bends an optical path from the surface of the document to the one-dimensional image sensor at right angles; A lens is provided between the dimensional image sensor and the mirror and forms an image of reflected light from the original onto the light receiving surface of the one-dimensional image sensor, and a tape with a high reflectance is attached to the inner surface to cover the light source. What is claimed is: 1. A document reading device comprising: a pipe-shaped reflection holder installed in a pipe and provided with an opening for irradiating the document.
