The data communication main body type mobile phone system in which data communication is performed by the data communication function with the notebook personal computer 41 attached to and connected to the PC 3 is adopted. Further, for example, a conventional mobile phone generally shown in FIG.
The voice communication type mobile phone system in which data communication is performed by the data communication function with a notebook computer 54 connected to a dedicated modem card 53 mounted in a JEIDA / PCMCIA compliant card interface slot using a dedicated cable 52 is adopted.

[0003]

Since the conventional portable telephone as described above employs a data communication-oriented type or a voice call-oriented type mobile telephone system, a connection for voice communication using an attached earphone / microphone 42 or a dedicated cable 52 is provided. A data communication connection by the dedicated modem card 53 is required, which is inconvenient.

[0004] The problem to be solved by the present invention is to fit into a card interface slot of a personal computer or the like so that a portable telephone with a data communication function can be operated easily and comfortably even when using either a voice call or data communication. Combination of a main unit that has only a data communication function (wireless function, modem function, etc.) with a shape and an adapter that has only a voice communication function (battery or keyboard) that can be separated from the main unit and that is unnecessary for data communication to be connected to a personal computer etc. An object of the present invention is to provide an integrated voice call / data communication type mobile telephone system in which voice communication is performed in a form and data communication is performed in a divided form.

[0005]

A portable telephone with a data communication function according to the present invention is provided with a main unit having a wireless function / modem function / card type interface function for data communication by being mounted in a card interface slot such as a personal computer and the data communication. Sometimes an adapter with an unnecessary battery / keypad function is integrated into a divisible structure, or through a separate interface dedicated connector instead of the adapter-side interface or card-type interface connection that matches the card-type interface function of the main unit The keypad operation information from the main unit side is transmitted from the adapter side to the main unit side, and the same voice communication as that of a normal mobile phone is performed in the combination mode and the data communication is performed in the split mode. Voice call /
It is characterized by adopting a data communication integrated mobile phone system. The wireless communication modem card according to the present invention is:
Attach a separately prepared adapter with a battery / keypad function to the modem card body for wireless data communication by inserting it into a card interface slot such as a personal computer, or match the card type interface function of the modem card body Instead of the interface on the adapter side or the card-type interface function, the adapter side transmits the keypad operation information from the adapter side to the modem card main body side via a separate interface dedicated connector to the modem card main body so that it can be used for voice communication. The above-mentioned problem is solved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A portable telephone with a data communication function according to an embodiment of the present invention has an integrated structure in which a main body 1 and an adapter 2 can be divided as shown in FIGS. 1 (a) and 1 (b). A voice call is made in the combined form (FIG. 1 (a)), and only the main body 1 with the adapter 2 removed is mounted on the card interface slot (compliant with JEIDA / PCMCIA) 31 of the personal computer 3 (FIG. 1 (b)). Perform data communication. The main body 1 is a card interface slot 31 of the personal computer 3.
It is equipped with only a wireless function and a modem function necessary for data communication in a shape that can be accommodated in a portable telephone. For example, as shown in FIG. A receiver 13 for outputting a received voice during a voice call, a communication monitor sound for data communication, a receiving circuit 14 for receiving a radio wave from the antenna 11, and a transmitting circuit 15 for transmitting a radio wave via the antenna 11. And a modem 16 for modulating and demodulating digital data during digital communication, a control circuit 17 for controlling the operation of the mobile phone, and an interface 18 for connecting a card interface slot 31 of the personal computer 3 and the adapter 2. The adapter 2 is detachable from the main body 1 and has only a battery, a keyboard function, and the like which are unnecessary for data communication connected to the personal computer 3. For example, a dial key 21 for inputting a telephone number to be called as shown in FIG. And a microphone 22 for inputting a transmission voice during a voice call, a battery 23 for supplying power for telephone,
And an interface 24 for connection to the computer.

The portable telephone with a data communication function according to the above-described embodiment has a main body 1 having only a data communication function which can be accommodated in a card interface slot of the personal computer 3 and a data communication which can be separated from the main body 1 and connected to the personal computer 3. An integrated voice call / data communication type mobile phone system in which a voice call is made in combination with an adapter 2 having only an unnecessary voice call function at times and data communication is performed in a divided form.

In the embodiment of the invention shown in FIG. 1, the liquid crystal display 12 and the receiver 13 may be mounted on the adapter 2 instead of the main body 1. The display required during normal data communication may be displayed on the display of the personal computer 3, and the need to monitor the communication sound during normal data communication is low. If necessary, the monitor sound from the built-in speaker of the personal computer 3 may be used. And the overall size of the mobile phone can be reduced.

In the embodiment of the invention shown in FIG. 1, the interface 18 has been described as using the interface with the JEIDA / PCMCIA compliant card interface slot of the personal computer 3 as the interface between the main body 1 and the adapter 2 as it is. 1 and adapter 2
May be separately provided as an interface with a dedicated connector or the like.

In the embodiment of the invention shown in FIG. 1, the card type interface has been described as being applied to the JEIDA / PCMCIA compliant specification.
It is applicable regardless of the size of the CIA-compliant card and the thickness of the types I to III. Also other interface specifications,
For example, it is needless to say that the present invention can be applied to a parallel serial interface specification of an external expansion connector of a notebook personal computer and a card type interface specification which will be standardized in the future.

[0011]

According to the portable telephone with data communication function of the present invention as described above, a main unit having only a data communication function, which can be accommodated in a card interface slot of a personal computer or the like, and which can be separated from the main unit during data communication by connection with a personal computer or the like. The data communication / voice call integrated mobile phone system is integrated and formed by combining with an adapter that has only unnecessary voice communication function. Compared with the conventional data communication-based or voice call-based mobile phone system It can be used not only for a data communication function by connecting to a personal computer or the like, but also for a voice communication function for the same feeling as a normal mobile phone. In addition, there is an effect that a large-capacity battery, a dial key, and the like can be mounted without being limited by a shape and a size that can be accommodated in a card interface slot of a personal computer or the like.
