L'invention concerne un mécanisme d'actionnement destiné à être utilisé pour régler un terminal d'affichage comprenant un disque rotatif (13) utilisé pour installer un terminal d'affichage (200) ; une unité d'embrayage, dont une première partie de mise en prise (21) est raccordée au disque rotatif (13) et une seconde partie de mise en prise (23) et la première partie de mise en prise (21) comprennent une pluralité de positions de mise en prise ; une unité d'entraînement (30), dont une extrémité de sortie est raccordée à la seconde partie de mise en prise (23) ; un arbre d'installation (15), qui pénètre dans l'unité d'entraînement (30) et l'unité d'embrayage, l'arbre d'installation (15) étant assemblé avec la première partie de mise en prise (21) d'une manière axialement limitée ; un élément élastique (40), dont une extrémité vient en butée contre l'arbre d'installation (15), et l'autre extrémité vient en butée contre l'unité d'entraînement (30) ; l'élément élastique applique une force de pré-serrage élastique axiale au niveau de la jonction de la première partie de mise en prise (21) au moyen de l'arbre d'installation de sorte que l'unité d'entraînement (30), l'unité d'embrayage et le disque rotatif (13) sont successivement pressés et la force de pré-serrage élastique permet à la seconde partie de mise en prise (23) et à la première partie de mise en prise (21) d'entrer en prise. L'unité d'embrayage accouple une structure de rotation manuelle et une structure de rotation automatique sous la forme d'un ensemble, ce qui permet de mettre en œuvre simultanément les rotations manuelle et automatique d'un terminal d'affichage sans interférence mutuelle.
