DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, the present invention will be described through embodiments of the present invention. However, the following embodiments do not limit the claimed invention and have the features described in the embodiments. Not all combinations are essential to the solution of the invention.

FIG. 1 shows an example of a front configuration of a portable telephone terminal 20 according to an embodiment of the present invention. Mobile phone terminal 20
Has a display unit 40, an operation unit 60, a reception unit 82 and a transmission unit 84 as transmission / reception units on the surface, an antenna 162 for wireless communication on an upper end surface, and a circuit inside. The display unit 40 has, for example, an LCD. The operation unit 60 has a switching key 64 in addition to a plurality of operation buttons 62. Receiver 82
Reproduces an audio signal as audio. The transmitting section 84 converts voice into a voice signal and outputs the voice signal to a circuit inside the mobile phone terminal 20.

FIG. 2 shows an example of the configuration of the back surface of the mobile phone terminal 20. The mobile phone terminal 20 has a battery pack 10
0, and a receiving unit 122 and a transmitting unit 124 which are transmitting and receiving units. The receiver 122 reproduces the audio signal as audio. The transmitting unit 124 converts the voice into a voice signal and outputs the voice signal to a circuit inside the mobile phone terminal 20. By using the receiving unit 122 and the transmitting unit 124, the user's ears and face do not directly touch the display unit 40 on the surface during a call, so that the display unit 40 is less likely to be stained by sweat or protein. . One of the receiving unit 122 and the transmitting unit 124 and the receiving unit 82 and the transmitting unit 84 illustrated in FIG. 1 may function as the receiving unit and the transmitting unit. In this case, one of the front surface and the back surface becomes the use surface and faces the human body.

FIG. 3 shows an example of an internal circuit of the portable telephone terminal 20. The mobile phone terminal 20 includes the control unit 140 and the wireless unit 1
60 is provided. The control unit 140 includes the display unit 40, the operation unit 6
0, receiver 82, transmitter 84, receiver 122, transmitter 1
24 and the wireless unit 160. Radio section 160 is connected to antenna 162 in addition to control section 140. In accordance with a signal from the switching key 64 of the operation unit 60, the control unit 140 determines a combination of the active receiving unit and the transmitting unit from the receiving unit 82 and the transmitting unit 84 to the receiving unit 122 and the transmitting unit 124.
Or the function of switching from the reception unit 122 and the transmission unit 124 to the reception unit 82 and the transmission unit 84, comparing the volume detected by the transmission unit 84 with the volume detected by the transmission unit 124, and A function for automatically operating a combination of a receiving unit including a large transmitting unit and a transmitting unit; transmitting a voice signal transmitted from the wireless unit 160 to the receiving unit 82 or the receiving unit 122; It has a function of transmitting an audio signal transmitted from the wireless communication unit 124 to the wireless unit 160 and a function of controlling display contents on the display unit 40 according to signals input from the operation buttons 62 and the switching keys 64. Radio unit 160
Has a function of converting a radio signal transmitted from the outside via the antenna 162 into an audio signal and transmitting the audio signal to the control unit 140;
And a function of converting an audio signal transmitted from the control unit 140 into a wireless signal and transmitting the wireless signal to the outside via the antenna 162. The control unit 40 may have a function of fixing the combination of the receiving unit and the transmitting unit that operates when a predetermined condition is satisfied. An example of the predetermined condition is a case where the transmitting unit continuously detects a volume equal to or higher than a predetermined value for a predetermined time.

FIG. 4 shows an example of the operation of the portable telephone terminal 20. When a call is started (step S20), the control unit 14
In the case of 0, the use surface is automatically selected and set from the front surface and the back surface (step S40), and the use surface is displayed on the display unit 40 (step S60). If the user wants to manually switch the used surface (step S80), the user operates the switching key 64 to switch the used surface from the front surface to the back surface or from the back surface to the front surface (step S100). At this time, the control unit 140 displays the switched use surface on the display unit 40 (step S12).
0). Then, when ending the call (step S14)
0), the user performs a predetermined operation to terminate the operation of the mobile phone terminal 20.

FIG. 5 shows an example of the operation of the control section 140 in step S40 of FIG. The control unit 140 compares the volume detected by the transmission unit 84 with the volume detected by the transmission unit 124 (step S42), and recognizes the transmission unit having a higher volume (step S44). Then, the combination of the receiving section and the transmitting section including the transmitting section with a large volume is automatically operated (step S46), and the surface to be used is automatically selected and set from the front surface and the back surface.

FIG. 6 shows a display example of the display unit 40 when the surface of the portable telephone terminal 20 is used as the use surface in steps S60 and S120 in FIG. Control unit 140
Displays the characters "table" in the display field 42 of the display unit 40. In this case, the user can recognize that the surface is selected as the use surface.

FIG. 7 shows that in step S60 of FIG.
Display unit 4 when the back surface of mobile phone terminal 20 is used as the use surface
The example of display of 0 is shown. The control unit 140 displays the characters “back” in the display field 42 of the display unit 40. In this case, the user can recognize that the back surface is selected as the use surface.

Although the present invention has been described with reference to the embodiment, the technical scope of the present invention is not limited to the scope described in the above embodiment. Various changes or improvements can be added to the above embodiment. It should be noted that such modified or improved embodiments may be included in the technical scope of the present invention.
It is clear from the description of the claims.

[0017]

As is apparent from the above description, according to the present invention, it is difficult for the user's ears and face to directly touch the display unit during a telephone call, so that dirt due to sweat, protein, etc. is less likely to adhere to the display unit. can do.
