ne System) and other portable wireless devices that use communication means 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.

[0003] A portable wireless device of this type is also known which has a folding mechanism to enhance portability.

[0004] As shown in FIG. 8, as an example of a conventional foldable portable radio, a first housing 21 and a second housing 22 are interposed between opposing surfaces 21 a, 22 a via a hinge 23. Is variably connected between approximately 0 degrees and 180 degrees, and the surface 2 of the first housing 21 facing the second housing 22.
1a, a key operation unit 25 and a transmission unit 24 are provided. A display unit 26 and a reception unit 27 are provided on a surface 22a side of the second housing 22 facing the first housing 21. There is known one provided with an antenna (not shown) at the end of one housing 21 or the second housing 22.

[0005] However, the foldable portable radio device 20 shown in FIG. 8 has a problem that the receiver 27 and the transmitter 24 are hidden when folded and closed, and it is impossible to make a telephone call as it is. . Therefore, when an incoming call is received in a folded state, it takes time and effort to open the first housing 21 or the second housing 22 and then perform an off-hook operation in order to make a call. ,
If it takes a long time to receive a call, there is a risk that the call will be disconnected.

Also, when folded, the receiving unit 27 and the transmitting unit 24 come close to each other, which causes a problem of howling.

To solve such a problem, Japanese Patent Laid-Open Publication No. Hei 11-187098 discloses a surface (outer surface) of the second housing 22 opposite to the facing surface 22a as shown in FIG. ), A second transmitter 28 and a second receiver 29 are provided, respectively, and an on-hook operation unit 30 and an off-hook operation unit 31 are provided on one of the side surfaces of the housing.

According to this technique, when an incoming call is received at the time of folding, by pressing the off-hook operation unit 31, the second reception unit 29 without opening the first housing 21 and the second housing 22. And the second transmitter 28 can be used to make a call, so that there is an advantage that the time required to shift to a call can be shortened and the labor for operation can be saved.

On the other hand, the portable wireless device 20 in which the angle between the opposing surfaces 21a and 22a is variably connected cannot see the display unit 26 in a folded state. Alternatively, an operation of opening the second housing 22 is required, and the operation is troublesome.
A portable wireless device 40 as shown in (b) has also been proposed.

The portable wireless device 40 comprises a first housing 41 and a second housing 42 which are arranged to face each other and are rotatable about axes perpendicular to the surfaces facing each other.
A key operation unit 45 and a microphone 44 as a transmitting unit are provided on the surface of the first housing 41 facing the second housing 42, and the first housing 41 of the second housing 42 On the opposite outer side, a device having a display unit 46 and one speaker 47 as a receiver has been proposed (see Japanese Patent Application Laid-Open No. 7-288860).

According to the portable wireless device 40, the display section 46 can be viewed regardless of when the first housing 41 and the second housing 42 are expanded or folded, so that the caller can be confirmed. There is an advantage that it can be easily performed.

[0012]

However, the portable wireless device 20 shown in FIG. 9 cannot see the caller because the display unit 26 cannot be seen even if an incoming call is received when the portable wireless device 20 is folded. There was an inconvenience that it was not possible to deal with unwanted calls.

Further, the transmitting units 24 and 28 and the receiving units 27 and 2
9 must be provided on the front and back of the second housing 22, respectively, so that the number of parts is increased, the structure of the radio is complicated, and the portable radio 20 is required to be reduced in size and weight. There was a problem that the requirements could not be fully satisfied.

On the other hand, in the portable wireless device 40 shown in FIGS. 10A and 10B, the display unit 46 is exposed even when the portable wireless device is folded, so that when a call is received, the caller can be immediately confirmed. However, as shown in FIG. 10 (b), when folded, the transmitting section 44 is hidden behind the receiving section 47, so that a telephone call cannot be made in the folded state. There is a problem that it is time-consuming to unfold the first housing 41 and the second housing 42 and perform the off-hook operation. In addition, when folded, the receiving unit 47 and the transmitting unit 44 come close to each other, which causes a problem of howling.

[0015]

And the first housing 1 and the second housing 2 by the second detection unit 17.
Check the deployment status of. For example, when an incoming call is detected, if the first detection unit 16 is off and the second detection unit 17 is on, the portable wireless device 10 is in the expanded state (FIG. 3). Incoming information and the like are displayed on the display unit 6 with the side facing upward, and the microphone 4 and the speaker 8 located farther from the microphone 4 (the end opposite to the hinge shaft 3) are operated, and the vicinity of the microphone 4 (hinge The speaker 7 near the axis 3) is deactivated. Then, an unshown off-hook operation unit is pressed down, and the speaker 8 is turned off.
The call can be made by bringing the user closer to the ear.

When an incoming call is detected, the first detecting unit 1
When the mobile phone 10 is in the ON state and the second detection unit 17 is in the OFF state, the portable wireless device 10 is in the folded state (FIG. 1). The microphone 4 and the speaker 7 farther from the microphone 4 (near the hinge axis 3) are operated, and the speaker 8 near the microphone 4 (the end opposite to the hinge axis 3) is not operated. And Then, the user can make a call by pressing an off-hook operation unit (not shown) and bringing the speaker 7 close to the ear. At this time, the portable wireless device 10 has not been deployed, and although not long enough to place the microphone 4 near the mouth,
By increasing the sensitivity of the microphone 4, the transmission sound can be sufficiently collected.
