Abstract
Disclosed is an image scanner, which has: a reflecting mirror for reflecting a light reflected from a scanned manuscript in a predetermined direction; a sub-scanning means for sequential sub-scanning which parallel moves on a plane which has an acute angle to the surface of the scanned manuscript while keeping the reflecting surface of the reflecting mirror perpendicular to the surface of the scanned manuscript; a focusing lens which focuses the light reflected from the scanned manuscript which is reflected by the reflecting mirror; and an one-dimensional image sensor which outputs a manuscript image by conducting a photoelectric conversion of the light reflected by the reflecting mirror which is focused on a light-receiving surface of the one-dimensional image sensor by the focusing lens.
