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, if 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-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. Note that this embodiment also describes a portable wireless TV phone which is a kind of portable wireless device as an example.

In FIG. 3, 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, etc., 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 telephone number input from the key operation unit 3 or a liquid crystal monitor for displaying 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. An earphone, which is the same as in the first embodiment. FIG. 2 is an external view showing a configuration of the portable wireless TV phone in a state where a flip part is closed.
Reference numeral 3 denotes an earpiece for outputting a reception sound when only voice communication is performed, and reference numeral 14 denotes a segment display unit 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.
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,
Perform a calling operation.

Then, after the line is wirelessly connected to the terminal of the other party, voice / image / character signals are transmitted / received between the terminals via the antenna 2 using the radio signal as a medium, and the voice information received from the terminal of the other party is a speakerphone. Speaker 10 or earphone 12 connected to earphone terminal 11
, And the image / character information can be received as a video output from the liquid crystal monitor 8. Also,
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, or if it is desired to transmit and receive only voice information, the flip section 7 is closed as shown in FIG. , Turn off the CCD camera 9
When the power is turned on in this state, the power is supplied from the battery unit 5 attached to the
Inputting the telephone number of the partner terminal while visually recognizing the segment display unit 14 from the key operation unit 3 of
A radio signal is transmitted from the antenna 2 via a radio circuit,
Perform a calling operation.

Then, after the wireless connection with the terminal on the other end, the audio signal is transmitted and received between the terminals using the wireless signal as a medium, and the audio information received from the terminal on the other end is transmitted through the earpiece 1.
3 or an earphone 12 connected to the earphone terminal 11 can output and receive audio. Also, voice information to be transmitted to the other terminal is voice-input by the microphone 4,
It is transmitted to the other party. Therefore, when wireless communication using only voice is performed, it is not a telephone call using a speakerphone that maintains a certain distance, but a telephone call by placing the earpiece 13 on the ear in the same manner as a normal portable wireless telephone by closing the flip unit 7. Can be.
