Claims

[Scope of Claim for Utility Model Registration] (1) First and second panels on which a transmissive original and a reflective original are placed, respectively, and are arranged so as to be movable in the horizontal direction.
a document table; a light source movable in the horizontal direction by a horizontal moving means within the device housing to irradiate the images of the transparent original and the reflective original in order to read the images separately; a first reflecting mirror mounted on the second document table so as to illuminate the reflective document placed on the first document table from below and reflect the light onto a first optical path substantially parallel to the surface of the document; Arranged so that the light traveling in the first optical path is reflected as light traveling in the second optical path parallel to the first optical path and in a direction opposite to the traveling direction of the light emitted from the first reflecting mirror. second and third reflecting mirrors; exclusion means arranged to exclude the second reflecting mirror from the first optical path by horizontal movement of the second document table; an imaging lens arranged to form an image of light onto a line image sensor; , the imaging lens forms an image on the line image sensor via a third reflecting mirror, and an image of a transparent original placed on the second original table;
The light from the light source moved in the horizontal direction by the horizontal moving means passes through the third reflecting mirror to the line image sensor by the imaging lens without passing through the first and second reflecting mirrors. An image reading device characterized in that it forms an image. (2) The light source is an aperture tube having an aperture of an appropriate shape and size on a part of its outer periphery for irradiating light in a predetermined direction, When reading an image of a reflective original placed on the first original table, the direction of light irradiation from this aperture is directed slightly obliquely from below to above the first original table, and the transparent original placed on the second original table is When reading the image, the aperture tube is moved horizontally by the horizontal moving means and placed while rotating about its tube axis from above to below the second document table. An image reading device according to claim 1 of the utility model registration claim.
