It is possible to prevent the 140 from flowing. In addition, since the projections 201 and 126 are kept in close contact with each other, the fixing piece can be prevented from being restored to the win position.

In addition, the pad unit 140 in a popped up state is made of any one selected from a key button or a liquid crystal screen, so that a function such as a call, a game, etc. can be performed using the key button in a popped up state or separately through the liquid crystal screen. The display information can be displayed. Meanwhile, the LCD screen may use a touch screen method. This is because it is possible to perform a separate multimedia function (call, game, etc.) using the touch screen method.

Next, when the pad unit or the mobile phone is used, the liquid crystal display unit is pressed in the opposite direction to open and overlaps with the key button unit. Then, the pressing state of the protrusion is canceled and the bracket is pressed by the compressive force of the elastic body holding the bracket. The bracket is brought into close contact with the bottom of the base frame by pivoting the fixing piece in a vertical direction.

Next, the inclined guide surface of the liquid crystal display unit presses one side of the pad unit 140 so that the pad unit 140 descends downward as the liquid crystal display unit moves. The state of being drawn in the button part is maintained and is pressed by the liquid crystal display part.

For example, the pad part may be up / down in parallel with the state in which the pad is always pushed upward by the elevating means or the sliding movement of the liquid crystal screen part. For this purpose, one side of the pad part is inclined. In addition, to maintain the pop-up state and to prevent the flow of the pad portion is to allow the fixing means to support the bottom of the pad portion.
