Abstract

Abstract A manuscript display apparatus includes a bow-shaped main body having a light emitting body housed therein translucent diffusion plate arranged on top of the main body to diffuse light emitted from the light emitting body, a support portion rotatably supported with respect to the main body, and a half mirror supported at the tip end of the support portion. When the manuscript display apparatus is to be used, a manuscript sheet is placed on top of the diffusion plate in such a way that its surface on which a manuscript is written faces down to th diffusion plate. The light emitted from the light emitting body is diffused by the diffusion plate and uniformly illuminate the manuscript sheet from the underside thereof. The light that passes through the manuscript sheet is reflected off the half mirror and therefor the manuscript is displayed as a virtual image. Because the virtual image is reversed at the half mirror, the virtual image displays the manuscript of the manuscript sheet in its original form.
