Abstract
The invention provides a device for efficiently mounting an original onto an image reading drum in an image scanning system. The mounting device includes a lower holder section and an upper holder section, each made of a flexible but hard plastic sheet. The original is held in between the lower holder section and the upper holder section and is attached onto the image reading drum, which has a predetermined thickness greater than a distance causing Newton's rings. Accordingly, image signals obtained by scanning the original effectively represent an original image without Newton's rings.
