Zusammenfassung: | PURPOSE:To provide a thin stereoscopic photograph viewing sheet which is conveniently carried and mailed and comparatively strong with respect to impact without damaging a function as a stereoscopic photograph sheet. CONSTITUTION:This is the stereoscopic photograph viewing sheet constituted by being provided with a lens part 2 having a pair of lenses 2a for stereoscopic vision at one end part of a postcard-like sheet 1 and an image part 3 where a pair of pictures for stereoscopic vision is arranged in parallel at the other end part and forming the lens part 2 and the image part 3 so as to rise through the focal distance of the lens. Then, the lens part 2 is constituted of a Fresnel lens film 2a whose thickness is 80-200mum and stuck to the end part of the sheet 1 so that it can be peeled. Since the stereoscopic photograph viewing sheet becomes almost the postcard-like sheet when it is not used, it is conveniently carried and mailed and it becomes comparatively strong with respect to impact and thin. |
