Alternatively, it is preferable that the second display is attached to an upper end surface of the first housing on the speaker side. Further, it is preferable that the second indicator is attached to a place where the second indicator can be seen from the direction in which the antenna is attached when the folding structure is closed.

[0007] It is preferable that the second display is attached to a place where the second display is visible from a direction not adjacent to the hinge when the folding structure is closed.

[0008] The portable telephone has detection means for detecting whether the folding structure is open or closed,
It is preferable that the operation of the first display is switched by the operation of the detecting means.

In the portable telephone according to the present invention, the first casing and the second casing have a folding structure in which the first casing and the second casing are foldable at a hinge portion. When the folding structure is closed, the portable telephone cannot be seen from the outside. A first display in a position, and a second display in a position visible from the outside even when the folding structure is closed, wherein the first display operates when the folding structure is opened. ,
There is provided a means for controlling the second display to operate in the closed state. The control means may control the second display to operate and the first display not to operate when the folding structure is closed.

Further, in the portable telephone according to the present invention, there is provided a portable telephone having a folding structure in which a first housing and a second housing are foldable by a hinge at the hinge portion. And a second display at a position outside even when the folding structure is closed, wherein the first display operates when the folding structure is opened, There is provided a means for controlling the second display to operate in the closed state. The control means may control the second display to operate and the first display not to operate when the folding structure is closed.

Next, the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the present invention, and FIG. 2 is a schematic diagram showing an example of a use state of the embodiment.

Referring to FIG. 1, a portable telephone 1 of the present embodiment has a first housing 1a and a second housing 1b having a folding structure that can be folded together by a hinge portion 2; The housing 1a includes a radio unit 4 to which the antenna 3 is connected, a display 8 for displaying communication and the state of the mobile phone 1, a display 11 on the surface where the antenna 3 is located, and displays 8, 1
1, a display driver 9 for supplying power and outputting character data, a selection circuit 10 for switching output of power and character data from the display driver 9 to the display 8 or 11, and a signal for switching to the selection circuit 10. Reed switch 12 for sending
And a speaker 5. The second housing 1 b turns on / off a control unit 5 for controlling the whole mobile phone 1, a battery 7 for supplying power to the whole, a key operation unit 6, and a reed switch 12. It comprises a magnet 13 and a microphone 14.

The display 8 includes first and second housings 1a, 1a,
1b is attached to the front of the speaker 15 and the reed switch 12 where the reed switch 12 is open.

The first housing 1a and the second housing 1b are
When the hinges 2 are folded around each other, the display 8 is not visible, and only the display 11 is visible.

In the folded state, the magnet 13 acts on the reed switch 12, and as a result, the selection circuit 10
Operates to transmit the power and character data from the display driver 9 only to the display 11. As a result, even in the folded state as shown in FIG. 2, the display 11 can confirm the display of only important information such as the electric field strength and the battery voltage in the state of waiting for an incoming call.

[0017]

As described above, according to the present invention, in addition to the first display on the front side, the second display which can be seen from the outside or in the closed state of the folded structure is provided even in the closed state of the folded structure. Necessary information can be checked on the second display unit, so even if you are in standby mode in which no sound is heard, you can easily recognize the incoming call to your machine, and you can respond faster to incoming calls than before. effective. Further, by not operating the first display in the state where the folding structure is closed, the battery can be used without wasting and the operating time can be extended.
