FIG. 4 is a perspective view showing a configuration of the portable wireless TV phone in a state in which a flip portion is closed.

[0004] The operation of the conventional portable wireless TV telephone configured as described above will be described below. When transmitting / receiving voice / image information to / from the other party's TV telephone terminal, the flip unit 7 connected to the apparatus main body 1 and the hinge 6 is opened, and the liquid crystal monitor 8 and the CCD camera 9 are rotated and fixed at positions where they can be easily viewed. Then, it is held at a certain distance from the liquid crystal monitor 8.

Next, when the power is turned on, the power is supplied by the battery unit 5 attached to the apparatus main body 1, and the telephone number of the partner terminal is input while visually recognizing the LCD monitor 8 from the key operation unit 3 of the apparatus main body 1. Then, a radio signal is transmitted from the antenna 2 via the control / wireless circuit of the apparatus main body 1 to perform a calling operation. Subsequently, after wireless connection with the terminal on the other end, voice / image / character signals are transmitted / received between the terminals via the antenna 2 using a wireless signal as a medium, and voice information received from the terminal on the other end operates as a speakerphone. Audio is output from the speaker 10 or the earphone 12 connected to the earphone terminal 11, and image / character information can be received as a video output from the liquid crystal monitor 8. The voice information to be transmitted to the partner terminal is voice-input by the microphone 4, and the image information is image-input to the CCD camera 9 and transmitted to the partner terminal.

On the other hand, when the other terminal is a telephone having only a voice communication function without a TV telephone function, the liquid crystal monitor 8 and the CCD camera 9 are turned off in the same manner as in the above operation to perform wireless communication with only voice information.

[0007]

However, like the above-mentioned conventional portable radio apparatus, the apparatus main body 1 as the first housing has a flip portion as the second housing, and the second main body has a flip portion. In the case where the display portion is provided in the housing, the display portion becomes invisible when the second housing is closed, so that there is a problem that it is difficult to use the display device with the second housing closed.

The present invention has been made in consideration of the above problems, and has as its object to provide a portable wireless device which is easy to use even when the second housing is closed.

[0009]

According to the present invention, in order to solve the above-mentioned conventional problems, a second housing is provided on a first surface facing the first housing in a closed state. The first provided
It is characterized in that providing the second display unit for displaying at least the telephone number on the back surface of the display unit of the. With this configuration, even when the second casing is closed,
Since the telephone number is displayed, a portable wireless device which is easy to use even when the second housing is closed can be provided.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of the present invention will be described.
This will be described with reference to the drawings. In this embodiment,
Similar to the description of the related art, a portable wireless TV phone, which is a kind of portable wireless device, will be described as an example.

In FIG. 1, reference numeral 1 denotes an apparatus main body having a built-in radio / control circuit;
Is a key operation unit for inputting a telephone number or the like, 4 is a microphone for voice input, 5 is a battery unit for supplying power, 6 is a rotatable hinge, and 7 is a flip unit connected to the apparatus main body 1 by the hinge 6. Reference numeral 8 denotes a liquid crystal monitor for displaying a telephone number or the like input from the key operation unit 3 or characters and image information sent from the other party, and 9 denotes a CCD for sending image information of a user of the apparatus to the other party. Camera 10 is a speakerphone that outputs a reception sound as a speakerphone, 11 is an earphone terminal, 12 is connected to the earphone terminal 11, and is used when it is difficult to hear due to ambient noise or when it is not desired to hear the other party's talk around. The earphone is the same as the conventional example. FIG. 2 is an external view showing a configuration of the portable wireless TV phone in a state in which a flip portion is closed, 13 is an earpiece that outputs a reception sound only when voice communication is performed, and 14 is an earpiece.
Is a segment display section for displaying character information such as a telephone number.

The operation of the portable wireless TV phone according to the present embodiment configured as described above will be described below.
