    摘要： An image sensor unit, and method, used in an image reading apparatus such as a facsimile machine, image scanner, copier machine, includes a feeding path through which a feeding document, having an imaged to be read, is passed. In the feeding path, the feeding document is passed over a contact glass through which a light from a light source illuminates an image on the feeding document. Reflected light is then detected with a detection and converted into image data. However, unless appropriate measures are taken, the integrity of the image data is subject to corruption as a result of electric noise generated from discharging of excess charge developed on the contact glass when the feeding sheet moves along side of the contact glass. The present image sensor includes a method and mechanism for passing the accumulated charge to ground, thereby avoiding the possibility of electrical discharge and associated electrical noise. Furthermore, the present image sensor includes a transparent thin film made of a material that prevents the accumulation of excess charge.

    摘要： An image scanner includes a stationary original plate on which a stationary original is placed and a moving original plate, over which a moving original is conveyed, aligned with the stationary original plate in a sub-scanning direction and tilted relative to the stationary original plate by a given angle. A reader is movable in the sub-scanning direction between a stationary original reading span disposed opposite the stationary original via the stationary original plate to read an image on the stationary original and a moving original reading position disposed opposite the moving original via the moving original plate to read an image on the moving original. The reader pressingly contacts the stationary original plate and the moving original plate as the reader moves in the sub-scanning direction.
