Portable viewing apparatus.

摘要

© A portable apparatus for simultaneously viewing a transparency and a reflection copy image. The apparatus preferably complies with American National Standard Institute standards «Direct Viewing of Photographic Color Transparencies» and «Viewing Conditions for the Appraisal of Color Quality and Color Uniformity in the Graphic Arts.» The apparatus includes a case which opens to have a cover portion positioned approximately horizontally near the top of an approximately vertical body portion. Pivotal side light shield plates can be opened to shield the sides of the apparatus from undesired ambient light, and a pivotal bottom plate can be positioned approximately horizontally for viewing prints. A transparency viewing plate having back lighting means for illuminating a transparency is positioned within the field of light from a source in the cover portion which strikes both the transparency and simultaneously the reflection copy image on the approximately horizontal plate.
