Abstract
(EN)
An image display apparatus is provided with a light source, screens (108, 109) on which light from the light source is radiated and an image is formed, an optical system for generating a virtual image by light from the screens (108, 109), a drive part (300) for causing the screens (108, 109) to move in the optical axis direction, and a support base (306) for supporting the drive part (300). The image display apparatus is further provided with a dynamic damper (308) installed in a non-movable part on the support base (306).
(FR)
La présente invention se rapporte à un appareil d'affichage d'image qui comprend une source lumineuse, des écrans (108, 109) sur lesquels la lumière provenant de la source lumineuse est diffusée et une image est formée, un système optique permettant de générer une image virtuelle grâce à la lumière en provenance des écrans (108, 109), une partie d'entraînement (300) servant à amener ces écrans (108, 109) à se déplacer dans la direction d'axe optique, et une base de support (306) destinée à porter la partie d'entraînement (300). L'appareil d'affichage d'image est en outre pourvu d'un amortisseur dynamique (308) installé dans une partie non mobile sur la base de support (306).
