In order to achieve the above object, the present invention provides an operation unit and a microphone on the upper surface of an apparatus main body, an earpiece and a second microphone on a lower surface of the apparatus main body, and further comprises an A flip part connected by a hinge, and a monitor, a CCD camera, and a speaker on a surface of the flip part stored in the apparatus main body when the flip part is closed, and the monitor is provided when the flip part is opened. ,
Keep a certain distance toward the CCD camera and speaker,
It can be used as a wireless TV phone by speakerphone or earphone while watching the monitor, and when the monitor is stored in the main unit side with the flip part closed, put the ear on the earpiece and use it as a normal mobile phone Is made possible.

[0009]

According to the present invention, with the above-described configuration, the terminal on the other end is also T
If you have a V-phone function, open the flip part, keep a certain distance toward the monitor, CCD camera and speaker, and use a speakerphone as a wireless TV phone to communicate with image / text information and voice information. When the terminal has only the voice communication function, the flip part is closed, and the earpiece part on the lower surface of the apparatus body is put on the ear, so that the terminal can be used as a normal mobile phone.

[0010]

An embodiment of the present invention will be described below 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, 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. The camera 10 is a speakerphone that outputs a reception sound as a speakerphone, 11 is an earphone terminal, and 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.
