In this case, the second operation key group 11B can be controlled so as not to be operated. In this case, the display unit 20 is controlled to restrict (for example, turn off) display based on a predetermined medium.

Subsequently, the operation of the mobile phone 1 in the deformed state will be described with reference to FIGS. 5 and 6. FIG. 5 is a diagram illustrating a third state in which the second surface 2B faces the upper surface and the display surface 21 faces the side.

As shown in FIG. 5, in the third state, the operation unit side body 2 side is arranged such that the second surface 2B faces the upper surface side, and the display unit side body 3 side is arranged on the side of the display surface 21 ( It is the state arrange | positioned so that it may face the near side in FIG. In the mobile phone 1, the connecting portion 4 is disposed on one end side in the width direction X of each of the operation unit side body 2 and the display unit side body 3, and therefore, as shown in FIG. It can be placed on a horizontal plane in a state where it is in a horizontal state and the display unit side body 3 is in a vertical state.

  In this state, the second operation key group 11B is arranged facing the upper surface side, and the display surface 21 is arranged facing the position seen from the predetermined direction D. That is, when there is a viewer on the predetermined direction D side, the viewer can preferably view the image displayed on the display unit 20 on the landscape screen and can easily select and adjust the function corresponding to the media function. It is an aspect.

When the viewer is viewing the display unit 20 from the direction D, the angle formed by the display surface 21 with respect to the second surface 2B is greater than 0 degree and smaller than 180 degrees (the display surface 21 is a method of the second surface 2B). When the angle formed with respect to the line is greater than −90 degrees and smaller than 90 degrees) , the display surface 21 is in a position that can be seen by the viewer. In this case, the second operation key group 11B is controlled so that an operation corresponding to a media function that displays information such as a predetermined image on the display unit 20 is possible.

  Next, the operation of the first operation key group 11A or the second operation key group 11B when the state changes in the mobile phone 1 will be described with reference to FIGS.

  First, the cellular phone 1 in the first state shown in FIGS. 1 and 2 is horizontally arranged with the second operation key group 11B on the upper surface.

  Next, the display unit side body 3 is rotated from the state K1 in which the display surface 21 faces the lower surface to the state K2 in which the display surface 21 is arranged to face the predetermined direction D. Let Thereby, it arrange | positions so that the display surface 21 can be seen from the predetermined direction D. FIG. In this state, since the angle formed between the display surface 21 and the second surface 2B is 90 degrees (ST1), the CPU 100 activates a predetermined media function (ST2). When the predetermined media function is activated, the display unit 20 starts image display based on the media function (ST3). At the same time, a predetermined operation using the second operation key group 11B becomes possible (ST4). A function corresponding to the activated media function is assigned to each operation key constituting the second operation key group 11B.

  Subsequently, the display unit side body 3 is rotated to a state of K3 in which the display surface 21 faces the upper surface. In this state, since the angle formed between the display surface 21 and the second surface 2B is 180 degrees (ST5), the CPU 100 stops the predetermined media function (ST6). When the predetermined media function is stopped, the image display based on the media function displayed on the display unit 20 is stopped (ST7). At the same time, the predetermined operation by the second operation key group 11B becomes impossible (ST8).

  According to the present embodiment, a mobile phone 1 that controls the operation of the first operation key group 11A or the second operation key group 11B according to the rotation state of the operation unit side body 2 and the display unit side body 3 is provided. can do.

  In addition, according to the present embodiment, it is possible to provide the mobile phone 1 that can maintain the display surface 21 in a form that is easy for the viewer to see and can operate while viewing the display surface 21 with the second operation key group 11B. In addition, since the second operation key group 11B arranged on the second surface 2B is provided, the mobile phone 1 can be operated without a sense of incongruity even when used horizontally. In addition, the mobile phone 1 is excellent in operability because the second operation key group 11B is arranged in the horizontal direction when used in the horizontal orientation.

  Further, according to the present embodiment, the media function is activated according to the rotation state, and an operation corresponding to the media function activated in the second operation key group 11B can be performed.

  As mentioned above, although preferred embodiment of this form was described, this invention can be implemented with a various form, without being limited to embodiment mentioned above. For example, in FIG. 5, a state in which the angle formed between the display surface 21 and the second surface 2B is larger than 0 degree and smaller than 180 degrees is directed to the same side when viewed from the predetermined direction D, but the present invention is not limited to this. For example, when the direction from the near side to the far side in FIG. 2A is a predetermined direction, the angle formed by the display surface 21 and the second surface 2B is larger than −90 degrees and smaller than +90 degrees. If you look to the side.

  Moreover, in this embodiment, although the connection part 4 whose rotation axis is 1 axis | shaft is demonstrated, it is not limited to this, It is the mobile telephone 1 which has a some rotation axis and was comprised so that folding was possible. Also good.

  In the above-described embodiment, the connecting portion 4 is arranged on one side in the width direction (the X direction shown in FIG. 5) between the operation unit side body 2 and the display unit side body 3. However, the present invention is not limited to this, and is arranged in the center in the same width direction, and similarly controls the operation of the first operation key group 11A and the second operation key group 11B according to the rotation state of both housings. It is good also as a structure which does.

(A) It is a front view in the 1st state which opened the mobile telephone 1. FIG. (B) It is a side view in the 1st state which opened the mobile telephone 1. FIG. (A) It is a side view in the 1st state which opened the mobile telephone 1. FIG. (B) It is a rear view in the 1st state which opened the mobile telephone 1. FIG. (A) It is a front view in the 2nd state which rotated the operation part side housing | casing 2 in the mobile telephone 1 of FIG. (B) It is a rear view in the 2nd state of the mobile telephone 1. FIG. 2 is a block diagram illustrating a configuration of a mobile phone 1. FIG. It is a figure explaining the 3rd state where the 2nd surface 2B faces an upper surface, and the display surface 21 faces the side. 4 is a flowchart for explaining the operation of the mobile phone 1.
