Abstract
In the structure of a multiscreen displaying apparatus, a set of units 20 is formed by piling unit displays 21A and 21B so that Fresnel lenses 23A and 23B are vertically arranged. One lenticular lens 10 is installed on the front of the Fresnel lenses 23A and 23B of each unit. Then protruded jaw parts 11 are provided at the upper and lower ends of the lenticular lens 10, and the lenticular lens 10 covers the Fresnel lenses 23A and 23B by hanging the jaw part 11 on the outer side of screen fitting frames 22A and 22B. Furthermore, in order to obtain vertical tension, a leaf spring 15 or the like is inserted between the jaw part 11 and the fitting frames 22A and 22B (hanging parts). It is possible to form a stereoscope by arranging plural units 20. Furthermore, the screen fitting structure of the projection units is that a casing type fitting frame 70 is installed on the side of the back of a screen 60. Metal fittings 81 for supporting is fixed to an inclined part 72 of a fitting frame 70 by screws 82. Fixing pieces 61 provided at the ends of a screen 60 are supported by the metal fittings 81 for supporting and the screen 60 is held between an engaging part 71 of the fitting frame 70 and the metal fittings 81 for supporting. By applying force in the direction of pushing out the screen 60 except the vertical direction at the inclined parts 72 and 81B, the screen 60 is held securely.
