PURPOSE: An input/output interface device of a mobile communication terminal is provided to comprise the first and the second liquid crystal panel with the first and the second key input unit on a front and a back of a folder, thereby enabling two users to simultaneously enjoy the same game. CONSTITUTION: The first key input unit(100) is formed on a terminal body. The first and the second liquid crystal panel(120,130) are formed on a front and a back of a folder coupled with the terminal body by the first hinge. The second key input unit(110) is detachable from the back of the folder by a fixing unit, and is sensed whether to be mounted or dismounted from the back of the folder by a sensor. If the sensor senses that the second key input unit(110) is detached in a game mode, a controller(140) outputs the same screen contents to the first and the second liquid crystal panel(120,130), and controls terminal operations in order to change the screen contents outputted by a key signal inputted from the first and the second key input unit(100,110).
