  The present invention relates to a stackable mobile terminal device such as a mobile phone or a PDA (Personal Digital Assistants), and more specifically, includes a plurality of casings connected to each other so as to overlap each other, and is provided in any casing The present invention relates to a stackable portable terminal device that can be exposed to the outside in a state in which the display surface of the display unit is overlapped and in other states, and output information can be displayed on the display surface in either state.

  Conventionally, a foldable mobile phone 2 as shown in FIG. 12 is generally known as a foldable mobile terminal device capable of folding two housings. The foldable mobile phone 2 is provided with a display surface 12 such as an LCD (Liquid Crystal Display) for displaying output information and a speaker 13 on an inner surface 10 of one housing 4, and an inner surface of the other housing 6. 14 is provided with a main operation section 16 and a microphone 15.

  The main operation unit 16 is provided with a cross key 18, a numeric keypad, and other various keys that can be designated in the vertical and horizontal directions so that items displayed on the display surface 12 can be selected.

  Such a foldable mobile phone 2 displays various functions of the foldable mobile phone 2 on the display surface 12 as a selection screen, and at this time, understands what the various functions are. In order to be able to do so, there are some which are displayed as characters and arranged as shown in FIG.

  However, in the foldable mobile phone 2 as shown in FIG. 12, when one casing 4 and the other casing 6 are folded, the display surface 12 can be viewed only after the casing is opened. In the folded state, there is a problem that even if information is output to the display surface 12, it cannot be browsed. In order to solve such a troublesome and troublesome problem, some display screens 12 face outward even in a folded state or a corresponding state.

  As such a portable terminal device, for example, there is an overlapped portable terminal device as described in Patent Document 1. In the overlapped portable terminal device, in the state where the two casings to be connected are opened, the display surface provided in one casing is on the inner side in the same manner as the posture of the folding cellular phone 2 shown in FIG. It is suitable.

  However, unlike the foldable mobile phone 2, such a conventional lap-type mobile terminal device has a structure in which one casing can be folded and folded while being twisted by 180 degrees at the connecting portion of the two casings. Thus, the two housings can be overlapped with the display surface facing outward.

However, even if the user can see the display surface, the main operation unit is covered and hidden by the display-side housing if the two housings are overlapped. It cannot be operated. In order to solve such a problem, for example, as in the invention described in Patent Document 2, there is one in which auxiliary operation keys are arranged on the side surface of the casing.

  By the way, since the width and area of the side surface of the casing are limited, it is difficult to place a cross key or a key corresponding thereto as an auxiliary operation key. Therefore, even if the various functions of the mobile phone 2 can be viewed through the display surface in a state where the two casings are overlapped, the items displayed in characters are arranged vertically as shown in FIG. Only the selection screens arranged one-dimensionally can be displayed, and the same selection screen is displayed on the display surface regardless of whether it is overlaid or opened.

  However, when displaying a selection screen in which items displayed in characters are arranged one-dimensionally on a display surface of a limited size like the mobile phone 2, the characters are small when trying to arrange many items at once. When the character is enlarged, the number of items that can be displayed at one time is reduced. When searching for a specific item, the selection screen must be scrolled by operating the auxiliary operation keys. There was an inconvenience in terms.

  In the conventional overlap type portable terminal device, the above-described selection screen is displayed regardless of the overlapped state and the opened state. Therefore, in the opened state, the up / down / left / right direction can be selected by the cross key or the like of the main operation unit. However, when selecting an item on the selection screen, only the operation in the vertical direction is used, so that the function of the main operation unit cannot be fully utilized.

  Therefore, the present invention provides different selection screens when the two casings are overlapped and opened, and when the main operation unit cannot be operated by overlapping the two casings, the operation is performed by the auxiliary operation unit. If the main operation unit can be operated by opening the two housings and displaying the selectable screen on the display surface, it is possible to perform operations that make use of the functions of the main operation unit and to make the display highly visible It is an object of the present invention to provide an overlapped portable terminal device in which a screen is displayed on a display unit.
