A three-dimensional rear projection screen that has substantially improved contrast by using a tinted layer disposed between the source of the projected light and the light diffusion layer. This tinted attenuation layer diminishes the back-scattered light more than it diminishes the desired forward-scattered light which makes up the image on the screen. The contrast of the image is thus improved because the reduction of the back-scattered light relative to the forward-scattered light diminishes the degradation of contrast caused by the impingement of spurious light onto opposite portions of the rear projection screen.

The object of this invention is to read an image (scan flow), when an original is being moved, above a scan flow glass member, so as to prevent degradation in image caused by dust or a scar on a scan flow glass. In order to achieve this object, the original which is being moved is illuminated by an illumination system comprised of an illumination light source and reflecting member and different from an illumination system in a reading apparatus body and comprised of an illumination light source and reflecting member. After a reflected light beam passes through a slit and the scan flow glass member, it forms an image on a line sensor, e.g., a CCD, by an imaging lens through a movable mirror.

The original is located above the scan flow glass member. Even if dust or a scar of about several tens μm is present on the scan flow glass member, it goes out of focus, so it can be prevented from forming an absent point of the line sensor such as a CCD.
