Abstract

Ce terminal mobile comprend : un cadre principal qui comprend une surface avant, une surface arrière, et une surface latérale et passe à un état parmi un premier état ou un second état présentant une taille plus grande que le premier état ; une unité d'affichage souple qui comprend une partie de surface avant positionnée sur la surface avant du cadre principal, une partie de surface arrière positionnée sur la surface arrière du cadre principal, et une partie de surface latérale positionnée entre la partie de surface avant et la partie de surface arrière et entourant une surface latérale du cadre principal ; un dispositif d'enroulement qui comprend une roue à arbre (une poulie) montée sur le cadre principal et tournant dans une première direction de rotation et une seconde direction de rotation, et une courroie comprenant une extrémité couplée à la partie de surface arrière de l'unité d'affichage souple et l'autre extrémité couplée à la roue à arbre ; et une unité de commande qui commande le dispositif d'enroulement afin de tourner dans la première direction de rotation, ce qui permet de commander un passage du second état au premier état. Le terminal mobile peut empêcher à l'unité d'affichage de se désengager lorsque la taille du terminal mobile diminue.
