  Such a foldable mobile phone 2 displays a selection screen 22 as shown in FIG. 18 on the display surface 12 so that the user can select them when using various functions. Yes.

  However, in the foldable mobile phone 2 as shown in FIG. 17, when one case 4 and the other case 6 are folded closest to each other, they must be opened apart from each other. There is a problem that the screen displayed on the display surface 12 cannot be seen and cannot be viewed even if information is output to the display surface 12 in a folded state.

  In order to solve such a problem that it is troublesome to open the housing 4 and the housing 6 of the foldable mobile phone 2 in order to view the display surface 12, not only the case where it is opened but also the folded state Or even if it is a state equivalent to this, there is what made the display surface 12 face outward.

  As such a portable terminal device, for example, there are stacked portable terminal devices as described in Patent Literature 1, Patent Literature 2, and Patent Literature 3. In the state in which the two casings to be connected are opened, these stacked portable terminal devices have a display surface provided on one casing on the outer side in the same manner as the folding cellular phone 2 shown in FIG. Facing.

  However, unlike the foldable mobile phone 2, the lap-type mobile terminal device described in Patent Documents 1 to 3 is folded while twisting one case by 180 degrees at the connecting portion of the two cases. The two casings can be stacked with the display surface facing outward.

Further, as another conventional overlap type portable terminal device, there is one described in Patent Document 4. In this conventional overlapping type portable terminal device, one casing provided with a display surface and the other casing provided with an operation unit are overlapped with the display surface and the operation unit directed in the same direction. Thus, the ends of the casings are connected by a shaft provided in a direction penetrating these two casings. This overlap type portable terminal device can be opened by an operation in which one housing is rotated by 180 ° about the axis with respect to the other housing, and the two display housings with the display surface facing outward. Therefore, the user can see the screen displayed on the display surface without opening the two housings.

And a control unit that activates the second application when the body is rotated counterclockwise with respect to the second housing .

  According to such an overlapped portable terminal device, the first screen displayed on the display unit when the first housing is rotated clockwise with respect to the second housing, and the first housing Since the second screen displayed on the display unit can be different from each other when rotated counterclockwise, various functions can be added to the opening / closing operation. The operability of the mobile terminal device can be improved.

  Further, the operation by the opening / closing operation of the first casing and the second casing is an operation of a completely different method from the operation of the numeric keypad, the cross key, etc., and the user can operate it clearly distinctly from the numeric keypad, the cross key, etc. Therefore, the operability of the stacked portable terminal device can also be improved.

  As described above, according to the stacked portable terminal device of the present invention, the first screen displayed on the display unit when the first housing is rotated clockwise with respect to the second housing. Since the second screen displayed on the display unit can be different from each other when the first housing is rotated counterclockwise, various functions are added to the opening / closing operation. Therefore, the operability of the stacked portable terminal device can be improved.

  For this reason, since the application and screen can be selected and activated only by opening and closing operations of the first housing and the second housing, the operability of the stacked portable terminal device can be improved, and a desired application or This is convenient because the operation for starting the screen can be simplified.

  Further, the operation by the opening / closing operation of the first casing and the second casing is an operation of a completely different method from the operation of the numeric keypad, the cross key, etc., and the user can operate it clearly distinctly from the numeric keypad, the cross key, etc. Therefore, the operability of the stacked portable terminal device can also be improved.
