A radio signal is transmitted from the antenna 2 via the control / radio circuit of the main body 1 to perform a call operation. Subsequently, after the wireless connection with the partner terminal, voice / image / text signals are transmitted / received between the terminals through the antenna 2 using the wireless signal as a medium, and the voice information received from the partner terminal operates as a speakerphone. Audio is output from the earphone 12 connected to the speaker 10 or the earphone terminal 11, and image / character information can be received as an image output from the liquid crystal monitor 8. Also, voice information to be transmitted to the counterpart terminal is voice-input by the microphone 4, and image information is input to the CCD camera 9 and transmitted to the counterpart side.
[0008]
On the other hand, when the partner terminal is a telephone with only a voice communication function without a TV phone function, the liquid crystal monitor 8 and the CCD camera 9 are turned off and wireless communication with only voice information is performed in the same manner as the above operation.
[0009]
(Embodiment 2)
The second embodiment of the present invention will be described below with reference to the drawings.
This embodiment will also be described by taking a portable wireless TV phone, which is a kind of portable wireless device, as an example.
In FIG. 3, 1 is an apparatus main body incorporating a radio / control circuit, 2 is an antenna for transmitting and receiving radio waves, 3 is a key operation unit for inputting a telephone number and the like, 4 is a microphone for inputting voice, 5 is A battery unit for supplying power, 6 is a pivotable hinge, 7 is a flip unit connected to the apparatus main body 1 by the hinge 6, 8 is a telephone number input from the key operation unit 3 or the like, or sent from the other party LCD, which displays incoming characters and image information, 9 is a CCD camera for sending image information of the user on the apparatus side to the other party, 10 is a speaker that outputs a received sound as a speakerphone, 11 is an earphone terminal, and 12 is This earphone is 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 story. The above is the same as in the first embodiment. FIG. 2 is an external view showing a configuration in which the flip part of the portable wireless videophone is also closed. Reference numeral 13 denotes an earpiece that outputs a reception sound only during voice communication, and reference numeral 14 denotes character information such as a telephone number. Is a segment display unit for displaying.
[0010]
The operation of the portable wireless TV phone of the present embodiment configured as described above will be described below. When transmitting / receiving voice / image information to / from the other party's TV phone 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 to a position where they can be easily seen. And held at a certain distance from the liquid crystal monitor 8. Next, when the power is turned on, power is supplied from the battery unit 5 attached to the apparatus main body 1, and the telephone number of the partner terminal is input from the key operation unit 3 of the apparatus main body 1 while being visually recognized on the liquid crystal monitor 8. A radio signal is transmitted from the antenna 2 via the control / radio circuit of the main body 1 to perform a call operation.
[0011]
Subsequently, after the wireless connection with the partner terminal, voice / image / text signals are transmitted / received between the terminals through the antenna 2 using the wireless signal as a medium, and the voice information received from the partner terminal operates as a speakerphone. Audio is output from the earphone 12 connected to the speaker 10 or the earphone terminal 11, and image / character information can be received as an image output from the liquid crystal monitor 8. Also, voice information to be transmitted to the counterpart terminal is voice-input by the microphone 4, and image information is input to the CCD camera 9 and transmitted to the counterpart side.
[0012]
On the other hand, when the other terminal is a telephone with only a voice communication function without a TV phone function, or when it is desired to transmit and receive only voice information, the flip unit 7 is closed as shown in FIG. When the power is turned on with 9 being turned off, power is supplied from the battery unit 5 attached to the apparatus main body 1, and the segment display unit 14 visually confirms the key operation unit 3 of the apparatus main body 1 while A telephone number is input, and a radio signal is transmitted from the antenna 2 via the control / radio circuit of the apparatus body 1 to perform a call operation.
[0013]
Subsequently, after the wireless connection with the partner terminal, the voice signal is transmitted and received between the terminals using the radio signal as a medium, and the voice information received from the partner terminal is the earphone 12 connected to the earpiece 13 or the earphone terminal 11. The sound is output from and can be received. In addition, voice information to be transmitted to the counterpart terminal is voice-input by the microphone 4 and transmitted to the counterpart side. Therefore, when performing voice-only wireless communication, it is not a call with a speakerphone that maintains a certain distance, but a call with the earpiece 13 placed on the ear in the same manner as a normal portable wireless phone by closing the flip unit 7. Can do.
