Abstract
a. Installation de reproduction de signaux vidéo. b. Installation caractérisée en ce qu'elle comporte un moyen de reproduction de signal 4 pour reproduire un signal vidéo sur l'une des pistes respectives, un signal vidéo sur l'une des pistes respectives, un moyen de support rotatif 3, 28, 29, une lame bimorphe 20 étant susceptible d'être déplacée d'une position de repos dans les deux sens transversaux à la direction de ces pistes, une extrémité de cette lame bimorphe étant reliée à ce moyen de support rotatif de façon à réaliser essentiellement une fixation en porte-à-faux rapport à celui-ci, et des moyens d'amortissement 51 étant prévus pour amortir la libre oscillation due à l'effort de courbure appliquée à cette lame bimorphe, ces moyens d'amortissement étant situés près de l'autre extrémité de la lame bimorphe.
