Abstract

La présente invention vise à répondre aux besoins d'un petit volume et d'une large zone d'affichage même sans utiliser un écran flexible. À cet effet, la présente invention concerne un terminal mobile comprenant : un corps pivotant sur lequel est montée une première unité d'affichage ; un corps principal situé derrière le corps pivotant dans la vue de la direction de l'épaisseur du corps pivotant et dans lequel est montée une seconde unité d'affichage ; un ensemble charnière au moyen duquel le corps pivotant est fixé rotatif au corps principal tout en maintenant la première unité d'affichage et la seconde unité d'affichage en parallèle l'une par rapport à l'autre, ce qui permet d'obtenir un état fermé dans lequel le corps pivotant est orienté dans la même direction que le corps principal, et un état de rotation dans lequel le corps pivotant est orienté dans une direction perpendiculaire à celle du corps principal ; un guide avant disposé au niveau du corps pivotant ; et un guide arrière disposé au niveau du corps principal et venant en prise de manière complémentaire avec le guide avant dans l'état fermé et l'état de rotation pour conserver l'état fermé ou l'état de rotation.
