PURPOSE:To obtain a simple and superior reconstruction display by sealing a hologram film in two sheets of transparent laminated films, forming the same into a cylindrical shape, mounting disclike vanes to the top end of the cylinder, providing an exothermic white light source in the lower part and rotating the cylinder by ascending air flow. CONSTITUTION:A hologram film F is sandwiched between two sheets of transparent laminated films 2, 3, and is sealed by thermal melt-sticking or the like, so that the part 4 of the film F is made opaque to make a light source 25 invisible. The part 4 may be disposed with characters or the like and used as an advertising area. This hologram 1 is formed to a cylindrical hologram 20. It is equally well to provide a cylindrical hologram 20 by arranging more than two sheets of the hologram film F. Rotary vanes 21 are provided to the top end of the cylinder 20, and the vanes 21 are supported by a support shaft 24 and a bearing 22 in such a manner that the vanes 21 are rotated by ascending air current. The hologram 20 is irradiated by the exothermic white light source 25, whereby reconstructed image are obtained. |
