ABSTRACT:
Light-shielding layers are adhered to the lower surface of a glass plate, spaced apart from each other and defining a slit having a width of L. An array of rod lenses is located below the glass plate, such that the optical axes of the lenses pass through the slit. The lower surface of the glass plate is generally covered, and exposed via the slit only. Hence, the leakage of lights reflected from points near a reading position into each photoelectric conversion element is minimized, whereby the element outputs a pixel signal faithfully representing that part of the image which is located at the reading position.
