The display processing section 9 is composed of an LCD driver and the like, and drives the display 1 under the control of the control section 8 to display an image.

The operation of the mobile telephone device 100 will be described below. The mobile telephone device 100 can be installed by fitting a touch panel 5 which is one of the instruction input units on the back surface, and can be installed in a hinge-like manner on the side surface by rotating in a hinge shape, and issue a command for instructing movement of a cursor or the like. It is a device that can be input.

That is, the touch panel 5 is shown in FIG.
As shown in (1), in the mobile telephone device 100, the display device 1 and the call key group 2 are fitted and installed on the back surface of the surface. The instruction detecting unit 7 detects position information indicating the position of the pressure applied to the touch panel 5 and notifies the control unit 8 of the movement amount of the position where the pressure is applied.

The touch panel 5 inputs, for example, an instruction to change the position at which the pointing cursor 15 displayed on the display 1 is displayed. At this time, the touch panel 5 inputs position information indicating the position where the pressure is applied, and the instruction detecting unit 7 detects this position information.

The instruction detecting unit 7 specifies the amount of movement of the pressed position from the detected position information, and notifies the control unit 8 of the specified amount of movement. The control unit 8 determines, based on the movement amount of the position to which the pressure is applied, notified from the instruction detection unit 7,
Pointing cursor 15 displayed on display 1
The amount of movement of the display position of is determined, and the pointing cursor 1
5 is specified. The control unit 8 controls the display processing unit 9 to display the pointing cursor 15 at the specified display position on the display 1.

Here, the instruction detecting unit 7 determines the amount of movement of the pressed position from the detected position information.
The processing shown in the flowchart of FIG. 6 is executed to adjust the amount of movement of the touched position on the touch panel 5.

That is, the instruction detecting section 7 first specifies the movement amounts Δx and Δy of the pressed position from the position information input by the touch panel 5 (step S).
1). Here, the movement amount Δx is a value indicating the distance that the pressed position has moved in the lateral direction of the touch panel 5, and the pressed position moves in a predetermined direction (rightward or leftward). The value becomes a positive value when moving, and becomes a negative value when moving in the opposite direction. Further, the movement amount Δy is a value indicating the distance moved by the position where the pressure was applied in the vertical direction of the touch panel 5, and the position where the pressure was applied moved in a predetermined direction (upward or downward). In this case, it becomes a positive value, and when it moves in the opposite direction, it becomes a negative value.

At this time, the instruction detecting unit 7 is provided with the changeover switch 6
Is "ON" or "OFF" (step S2). That is, instruction detection unit 7 determines whether or not touch panel 5 is fitted and installed on the back of mobile telephone device 100.

The instruction detecting section 7 determines that the changeover switch 6
N ”(“ O ”in step S2).
N ″), assuming that the touch panel 5 is fitted and installed on the back of the mobile telephone device 100, the above-described step S1 is performed.
The sign of the lateral movement amount Δx specified in is reversed (step S3).

On the other hand, the instruction detecting section 7 is provided with a changeover switch 6
Is determined to be "OFF" (in step S2, "
OFF "), and the touch panel 5 is
Is determined to be not fitted to the back surface of step S3, the process of step S3 is skipped, and the process proceeds to step S4.

The instruction detecting unit 7 delivers the movement amounts Δx and Δy adjusted in this way to the control unit 8 (Step S).
4).

By the processing described above, the instruction detecting unit 7
The moving direction of the position where the touch panel 5 is pressed on the touch panel 5 depends on whether the touch panel 5 is fitted and installed on the mobile phone device 100 or when the touch panel 5 is installed on the side surface of the mobile phone device 100. Is adjusted by the control unit 8 so as to be specified in the opposite direction.

Here, the touch panel 5 is fitted and installed on the mobile telephone device 100 by rotating in a hinge shape about an end (one of the side ends) as an axis, or the mobile telephone device 100 Or can be installed on the side. Therefore, the user can move the display position of the pointing cursor 15 using the touch panel 5 without feeling uncomfortable by the instruction detection unit 7 executing the above-described processing to adjust the movement amount Δx.

Thus, for example, as shown in FIG. 7, when the touch panel 5 is installed on the back of the mobile telephone device 100 and the position on the touch panel 5 where the pressure is applied moves left and right, the moving direction is changed. Accordingly, the display position of the pointing cursor 15 can be appropriately moved right and left. Also, as shown in FIG. 8, even when the touch panel 5 is installed on the side surface of the mobile telephone device 100, if the position on the touch panel 5 where the pressure is applied moves right and left, the pointing cursor according to the moving direction. 15 can be appropriately moved left and right.

As described above, according to the present invention,
A touch panel 5 having a wide input surface is provided by installing a touch panel 5 for indicating a display position of an image displayed by the display 1 on a back surface of a housing surface provided with the display 1 and the call key group 2 and the like. And input of instructions becomes easier. In addition, the touch panel 5 can be installed on a side surface of the mobile telephone device 100 by rotating in a hinge shape, and can be installed at a position suitable for the user's convenience and easily input an instruction.

In the above embodiment, the touch panel 5 is described as being hinged about one of the side ends as an axis, but the present invention is not limited to this. That is, for example, as shown in FIG. 9, the touch panel 5 may be hingedly rotated about the upper end or the lower end.

In this case, the instruction detecting unit 7 determines the moving amount Δ specified from the position information input from the touch panel 5.
of the movement amount Δy of x and Δy,
N "or" OFF "may be adjusted.In other words, the instruction detecting unit 7 includes a case where the touch panel 5 is fitted and installed in the mobile telephone device 100; The control unit 8 adjusts the movement direction of the position where the pressure is applied on the touch panel 5 in the case where the mobile phone device 100 is installed on the upper or lower surface of the mobile telephone device 100 so as to be specified upside down.

An input device such as a cross key or a joystick may be installed on the back of the mobile telephone device 100 so that it can be hinged and installed on an adjacent housing surface (upper surface, lower surface, or side surface). In this case, for example, the display position of the icon selection cursor 16 can be moved using the cross key, and when a predetermined operation such as pressing of the cross key is performed, the control unit 8 controls the communication processing unit 10 to control the communication processing unit 10. Alternatively, communication with the other party may be performed.

In the above embodiment, an example in which the portable terminal is applied to the mobile telephone device 100 has been described. However, the present invention is not limited to this, and the present invention is applied to a normal portable terminal having no communication function such as a PDA (Personal Digital Assistants). Is also applicable.
