Is a speaker that outputs a reception sound as a speakerphone, 11
Is an earphone terminal, and 12 is an earphone connected to the earphone terminal 11 and 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. FIG. 4 is a perspective view showing a configuration of the portable wireless TV phone according to the present embodiment in a state where a flip part is closed.

[0007] The operation of the portable wireless TV telephone according to the present embodiment 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 mounted on 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 a manner similar to the above-described operation to perform wireless communication with only voice information.

As described above, according to the present embodiment, when the flip unit 7 is opened to perform communication, the antenna 2 projects in a direction away from the user's body, so that the antenna 2 is affected by the user's body. This makes it difficult to receive radiation, secures antenna gain, and suppresses unnecessary radiation due to matching errors.

(Embodiment 2) Hereinafter, Embodiment 2 of the present invention will be described with reference to the drawings.

In FIG. 1, reference numeral 1 denotes an apparatus main body having a built-in radio / control circuit, 2 denotes an antenna for transmitting and receiving radio waves,
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 telephone according to the present embodiment 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 liquid crystal monitor 8 from the key operation unit 3 of the apparatus main body 1. Control of main unit 1
A radio signal is transmitted from the antenna 2 via a radio circuit,
