The above is the basic configuration of the foldable portable telephone device having the touch panel 7. FIG. 3 is a diagram illustrating a small protrusion 70 additionally provided at the center of the surface of the key switch 1 inside the key switch-side housing 20, and FIG. 4 is a diagram illustrating a height relationship between the protrusion 70 and the protrusion 50. It is.

As shown in FIG. 4, the height of the projection 70 is lower than the height of the projection 50. The projection 70 shown in FIGS. 3 and 4 does not touch the touch panel 7 when the normally foldable mobile phone device is closed because the height of the projection 70 is lower than the projection 50. FIG. 5 is a diagram for explaining external pressure applied to a foldable mobile phone device. As shown in the figure, when the foldable mobile phone device is closed, a strong force is further applied in the closing direction due to various causes.

When a strong force is applied, the projection 50
The gap between the surface of the key switch 1 of the key switch-side housing 20 and the surface of the touch panel 7 of the touch panel-side housing 30 is narrowed. That is, when an external force is applied, the distance is reduced in proportion to the applied external force. The protrusion 70 contacts the touch panel 7 when it is narrowed to a certain extent or less. By the contact of the projection 70, the breakage of the foldable portable telephone device due to the external pressure is predicted.

When any external force is applied, the protrusion 7
Whether 0 touches the touch panel 7 can be adjusted by the size of the protrusion 70, the size of the protrusion 50, and the hardness of the rubber embedded in the recess 60. Here, the foldable mobile phone device according to the present invention is carried in a bag or the like in a state of being folded by a user's hand,
Assuming that the baggage is subjected to strong pressure by being sandwiched by other luggage or the like in the bag, the operation of preventing the foldable mobile phone device from being destroyed by the external pressure will be described below.

FIG. 6 is a flowchart for explaining the operation of the external pressure destruction judging section 5A of the control section 5 in FIG. As shown in this figure, in step S1, when the foldable mobile phone device is in the folded state, the open / close detection switch 10 causes the external pressure destruction determination unit 5A of the control unit 5 to change the state in which the mobile phone device is folded. To recognize that
In step S2, when the above recognition is made, it is determined whether or not the projection 70 in FIG.

In step S3, when the above-mentioned contact is made, the contact is notified from the touch panel 7 to the external pressure destruction judging section 5A. In step S4, the external pressure destruction determination unit 5A determines that dangerous external pressure has been applied by receiving a notification of contact in a state where the mobile phone device is folded.

In step S5, the external pressure destruction judging unit 5
Based on the determination of A, the control unit 5 causes the buzzer 3 to sound a warning sound. In step S6, the warning sound enables the user to recognize that dangerous external pressure is being applied to the foldable portable telephone device, and furthermore, the foldable portable telephone device is externally disconnected. It is possible to take it out of the bag or the like under pressure and bring it to a state where no external pressure is applied.

When the external pressure is removed, the projection 70 separates from the touch panel 7 and returns to a state where it does not touch. External pressure destruction judging unit 5 that detects a state where there is no touch on touch panel 7
A makes a determination to stop the buzzer 3 from sounding the warning sound, and based on this determination, the control unit 5 stops the buzzer 3 from sounding and ends the processing.

If the contact of the projection 70 with the touch panel 7 is not released, the flow returns to step S5, and the buzzer 3 continues to emit a warning sound. The condition under which the external pressure destruction determining unit 5A uses the buzzer 3 to determine the sounding of the warning sound caused by the external pressure is when the foldable mobile phone device is closed. Therefore, when a user normally opens and uses the touch panel 7 to input characters or the like, it is not determined that a warning sound is sounded.

Therefore, according to the present invention, the size of the protrusion 50 of FIG.
The magnitude of the external pressure, which is a condition for performing the sounding operation of the warning sound described for the operation of the present embodiment, can be adjusted by the size of the projection 70 in FIG. For this reason, it can be adjusted so that a warning sound is emitted when a slightly weaker force is applied than the external pressure that is enough to break the foldable portable telephone device.

By this adjustment, a warning sound can be sounded before the foldable portable telephone device is damaged by external pressure, so that the damage can be prevented beforehand.
In addition, the foldable mobile phone device according to the present embodiment performs a sounding operation of a warning sound every time when an external pressure of a certain degree or more is applied, as described in the above embodiment, The user can in each case recognize that such use places dangerous external pressure on the foldable mobile telephone device.

[0036] With this recognition, the user can take care not to carry out the same dangerous handling when carrying and handling the foldable portable telephone device as when a warning sound is emitted. A situation in which dangerous external pressure is applied to the mobile phone device can be avoided in advance. Further, in particular, it is possible to configure only with the parts already possessed without requiring an additional circuit or the like.

FIG. 7 is a diagram showing a modification of FIG. As shown in this figure, a configuration different from that of FIG. 1 is an additional LED (Light Emitting Device).
e; light emitting device) 11. The LED 11 blinks the LED 11 instead of a warning sound when detecting that a dangerous external pressure is applied to the foldable mobile phone device,
The user can be warned visually instead of sound.

As shown in the figure, a configuration different from that of FIG. 1 is a nonvolatile memory 12 additionally provided. The non-volatile memory 12 is a memory that retains its contents even when the power of the foldable mobile phone is turned off. When a harmful external pressure is applied to the foldable mobile phone, an alarm sound is issued. Instead of sounding, the fact that an external pressure is detected is stored.

In the nonvolatile memory 12, it is assumed that the pressure detected can be recorded for several ten times. The history of the record of the detection of the external pressure stored in the non-volatile memory 12 can be read, for example, when the foldable mobile phone device receives a failure at a maker of a foldable mobile phone device, a store, or the like. I can do it.

An employee, a store clerk, or the like who has received a failure may use certain information to determine whether the failure of the foldable portable telephone device is caused by a user's handling or has been broken naturally. Will be possible. Note that, as another application of the present invention, for example, in a device equipped with a touch panel and having a lid that covers the touch panel, when the lid is closed, contact with the touch panel is detected, The presence or absence of pressure may be detected.

[0041]

As described above, according to the present invention,
Equipped with a touch panel for the purpose of character input and the like, and by using the structure of the mobile phone device that is folded to enhance portability, it already has no special circuit etc. A function that can detect that the mobile phone device has been subjected to dangerous external pressure by using only parts, emits a warning sound when a dangerous external pressure is received, and gives the user a dangerous external pressure. It is possible to recognize that a target pressure is applied, to call attention to use, and to avoid damage to the mobile phone device due to external pressure.
