BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a personal mobile communication device, and more particularly, to a mobile communication device that can be used by being attached to and detached from a main body to transmit and receive data and text as well as voice.

A typical type of personal mobile communication device is a cellular telephone. By using this mobile phone, users are provided with the convenience of talking with other users not only indoors but also outdoors.

On the other hand, with the development of communication technology, personal communication devices (Personal Communication Apparatus) is transforming into a form that can service not only the functions of the mobile phone but also many other functions. Personal portable communication devices such as PDAs (Personal Digital Assistants), which have been proposed and developed in recent years, serve not only mobile phone functions, but also electronic notebook functions, fax (FAX) functions, and computer (PC) communication functions. For example, "PDA Multi X" manufactured and sold by LG Electronics Co., Ltd., and "Pinocchio ALA" manufactured and sold by Japan Songha Electric Industrial Co., Ltd. (松下 電器 産業 株式會社, Panasonic) A personal portable communication device such as "P1" serves not only a mobile phone function but also an electronic organizer function, a fax function, and a PC communication function.

However, the personal portable communication device as mentioned above has a disadvantage in that the size is large because the components serving each function are all implemented in one device. For example, the size of the "PDA Multi X" is 153mm (W) x 65.8mm (D) x 33mm (H) and the weight is 310g, the size of the "Pinocchio ALA-P1" is 160mm (W) x 80mm ( D) × 20 mm (H) and weighs 270 g. In fact, many users of mobile phones are generally carrying a mobile phone in a pocket. However, the personal mobile communication devices have a disadvantage in that they do not meet the needs of the user, that is, it is difficult to carry the personal mobile communication device in a pocket. .

Therefore, many users carry the personal digital communication device in a bag or carry it in their hands instead of carrying it in a pocket. However, it is inconvenient to use the device because the user must carry the device out of the bag every time in order to carry the personal portable communication device in a bag and use any one of the functions serviced by the personal mobile communication device. It can be said that there is a ham. On the other hand, when the user carries the personal portable communication device directly in his hand, there is a possibility that the personal portable communication device may be lost if the user carelessly handles it during movement.

Accordingly, an object of the present invention is to reduce the size of a personal portable communication device connected to a wireless communication network to perform communication.

Another object of the present invention is to carry a personal portable communication device connected to a wireless communication network to carry in a pocket and to carry easily.

Still another object of the present invention is to make it easier to use a personal mobile communication device connected to a wireless communication network to perform communication.

Another object of the present invention is to prevent the risk of loss of a personal portable communication device connected to a wireless communication network for communication.

A personal portable communication device according to the first aspect of the present invention for achieving these objects is: a front structure of the communication device, having at least a first transmitter and a second transmitter, and the first transmitter A mobile phone which is wirelessly connected to the wireless communication network to perform voice, data or text transmission and reception; Has a structure that can be mounted on the back of the communication device, when mounted on the communication device is connected to the mobile phone by wire to perform wireless data or text transmission and reception with the wireless communication network through the mobile phone, and from the communication device When detached, the mobile communication device is wirelessly connected to the mobile phone, and is an auxiliary communication unit that performs data or text transmission / reception with the wireless communication network through the second transmitter / receiver of the mobile phone.

According to a second aspect of the present invention, there is provided a personal portable communication device comprising: a main body including at least a first transmitter and a second transmitter, and wirelessly connected to a wireless communication network via the first transmitter to perform voice, data, or text transmission and reception; Wow; It has a structure that can be mounted on the main body, when mounted on the main body is connected to the main body by wire and performs voice, data or text transmission and reception with the wireless communication network through the main body, and when detached from the main body And a portable device wirelessly connected to the main body and performing voice, data, or text transmission and reception with the wireless communication network through a second transmitter / receiver of the main body.

To transmit and receive time text and data signals.

The CPU 110 controls the overall operation of the mobile phone 100. In particular, in the present invention, the mobile phone 100 determines whether any of the electronic notebook unit 200, the PC unit 300, and the FAX unit 400 is mounted on the connector 128. According to the determination result, the CPU 110 receives a text signal or a data signal provided from the electronic organizer unit 200, the PC unit 300, or the FAX unit 400 through the modem 122, or the connector 128.

The antenna ANT11 radiates a radio frequency (RF) signal provided from the transceiver 112 into the air and allows the RF signal radiated in the air to be received by the transceiver 112. The transmitter / receiver 112 converts a signal applied from the baseband processor 120 into an RF signal in the transmission mode operation under the control of the CPU 110. The signal applied from the baseband processor 120 to the transceiver 112 is converted into an RF signal as an operation such as modulation, frequency up conversion, filtering, and power amplification is performed.

The modem 122 inputs data and text signals applied from the transceiver 126 or a microphone signal, and then inputs a demodulated and decoded audio signal from the user processed by the voice processor 124 and outputs the same to the CPU 110. In addition, the modem 122 inputs a signal applied from the CPU 110, encodes and modulates the signal, and outputs the processed signal to the transceiver 126 when the processed signal is a data and text signal under the control of the CPU 110. Will output The voice processor 124 may be generally implemented as a digital signal processor (DSP). The microphone MIC applies the voice spoken by the user to the voice processor 124. The speaker SPK transmits the voice signal processed by the portable communication device 100 to an external user.

The transceiver 126 converts data and text signals provided from the modem 122 into RF signals and outputs them to the antenna ANT12. The transceiver 126 converts RF signals received from the antenna ANT12 and outputs them to the modem 122. At this time, the transmitting and receiving unit 126 performs the frequency up-conversion, filtering, and amplification operation, and during the receiving operation, the transmitting unit 126 performs the amplification, down-frequency conversion, and filtering operation.
