Mobile Communication) and PHS (Personal Handy-ph)
Portable wireless devices using communication means such as one system) are widely used, and W is being developed as a next-generation technology.
Devices using communication means such as CDMA (Wide band CDMA) and CDMA2000 are being developed. In order to enhance portability, a portable wireless device of this type is known to have a foldable structure. However, in such a foldable portable wireless device, when the portable wireless device is folded, the display unit becomes invisible from the outside. Had been lost. For this reason, as shown in JP-A-6-37697, a second portable wireless device having a structure in which the display function is not impaired even in the folded state can be viewed from the outside even when folded. Some have a display unit.

[0003]

However, even in the portable wireless device having this structure, there is a problem that it is difficult to see the display of the exposed second display unit at night or in a place where the illumination is dark. For this reason, it is conceivable to provide illumination to each display unit to make it brighter. However, when each display unit is illuminated by illumination, a large load is imposed on the battery, and the battery runs out in a short time. There was a problem that it would.

The present invention has been made in view of the above circumstances, and provides a portable wireless device capable of easily confirming a display in a folded state even at night or in a dark place, and having a long battery life. It is intended to provide.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable wireless device according to an embodiment of the present invention will be described below with reference to the drawings. 1 and 2, reference numeral 1 denotes a portable wireless device. This portable radio is
It has a first housing 2 and a second housing 4 rotatably connected to an upper end of the first housing 2 by a hinge 3. By rotating the second housing 4, the second housing 4 is opened and closed with respect to the first housing 2. In other words, by turning the second housing 4 from the state where the second housing 4 is closed (the state in FIG. 2), the state where the second housing 4 is opened (the state in FIG. 1) is obtained. On the contrary, by rotating the second housing 4 in the opposite direction from the state where the second housing 4 is opened,
The second housing 4 is in a closed state.

[0008] When the second housing 4 is closed,
A main display unit (first display unit) 11 is provided on the front side, which is a side to be combined with the housing 2, and a sub display unit (second display unit) 12 is provided on the back surface. . The main display unit 11 and the sub display unit 12 are formed of liquid crystal plates provided at positions facing the main display unit window 11a and the sub display unit window 12a formed in the second housing 4, respectively. Various contents are displayed on the main display unit 11 and the sub display unit 12. The second housing 4 has an upper end on the front side thereof,
A speaker (sound output means) 13 is provided.

The first housing 2 is provided with a plurality of operation keys (input means) 14 for operation on the front side closed by the second housing 4. Can be entered. Also,
The first housing 2 is provided with a microphone (sound input means) 15 at the lower end on the front side, and an extendable antenna 16 on the back side at the upper end. Communication of various communication data such as voice data, character data, and image data is performed via an antenna.

According to the portable wireless device 1, the second
When the housing 4 is opened, voice input is performed by the microphone 15, and the voice of the other party, the ringtone,
Alarms and the like are issued.

Next, the function of the portable wireless device 1 will be further described with reference to a functional block diagram shown in FIG. In the figure, reference numeral 22 denotes a detection switch (open / close detection means). The detection switch 22 detects the open / closed state of the second housing 4 with respect to the first housing 2, and outputs a detection signal to the control unit (control means) 21. The second housing 4 includes a main illuminator (first illuminator) 24A and a sub illuminator (second illuminator) 24A.
B is provided, and the main display unit 11 and the sub display unit 12 are respectively illuminated by the main illuminator 24A and the sub illuminator 24B. Also,
These main illuminator 24A and sub illuminator 24B include:
A driver (power supply switching means) 23 is connected.
The driver 23 selectively selects a power supply path from the battery 26 to the main illuminator 24A and the sub illuminator 24B. The controller 23 is connected to the driver 23, and the controller 21 outputs a switching control signal to the driver 23 based on a detection signal from the detection switch 22.

A wireless unit (communication means) 25 transmits and receives various communication data such as voice data, character data, and image data to and from a partner terminal via an antenna 16 using a wireless communication line. Things. The communication data received by the wireless unit 25 is extracted by an audio processing unit (not shown), and the audio is output from the speaker 13. The voice input from the microphone 15 is input to the voice processing unit as a voice signal, converted from the voice processing unit into voice data, transmitted to the wireless unit 25 as communication data, and transmitted from the wireless unit 25 via the antenna 16. To be sent to the other party's terminal.

Next, the main illuminator 24 by the control unit 21
The control of A and the sub-illuminator 24B will be described. Second
When the housing 4 is opened from the closed state, the detection switch 2
The control unit 21 determines that the second housing 4 has been opened based on the detection signal from the second housing 4. Thereby, the control unit 21
A switching control signal is output to the driver 23 so that the power of the battery 26 is supplied to the main illuminator 24A to illuminate the main display unit 11. Therefore, the power from the battery 26 is supplied only to the main illuminator 24A via the driver 23, and the main illuminator 24A is turned on.
The main display 11 is illuminated.

When the second housing 4 is closed from the open state, the control unit 21 determines that the second housing 4 is closed based on a detection signal from the detection switch 22. Thereby, the control unit 21 outputs a switching control signal to the driver 23 in order to supply the power of the battery 26 to the sub illuminator 24B and illuminate the sub display unit 12. Therefore, only the power from the battery 26 is supplied to the sub illuminator 24B via the driver 23, and
4B is turned on, and the sub-display 12 is illuminated.

As described above, according to the portable wireless device 1, when the second housing 4 is open, the main display 11
Only the main illuminator 24A that illuminates the
The control unit 21 controls the driver 23 so that power is supplied only to the sub-illuminator 24B that illuminates the sub-display unit 12 in a state where the second housing 4 is closed and the main display unit 11 is hidden. Therefore, even at night or in a dark place, one of the main display unit 11 and the sub-display unit 12 can be illuminated according to the open / closed state of the second housing 4 to easily confirm the display. The main illuminator 24 is closed in a state where the second housing 4 is closed and the main display unit 11 is hidden.
A can be eliminated by supplying power to A or supplying power to the sub-illuminator 24B in a state where the second casing 4 is opened and the sub-display unit 12 is not used. Battery life.

[0016]

As described above, according to the portable wireless device of the present invention, the following effects can be obtained. According to the portable wireless device of the first aspect, when the second housing is open, power is supplied only to the first lighting means for illuminating the first display means, and the second housing is closed. The control means controls the power supply switching means so as to supply power only to the second lighting means for illuminating the second display means with the first display means being hidden. Even in a dark place, it is possible to easily confirm the display by illuminating one of the display means according to the open / close state of the second housing, and furthermore, the second housing is closed. Supplying power to the first lighting means in a state where the first display means is hidden,
It is possible to eliminate waste of power due to supplying power to the second lighting means in a state where the second casing is opened and the second display means is not used, and the battery lasts longer. Can be.
