Consists of

Next, the operation of this embodiment will be described with reference to FIG.
This will be described with reference to FIGS. Normally, when the mobile phone 1 is used for talking outside and outside, the mobile phone 1 is held and the phone call is performed, and the charger 2 is not used. That is, in this case, the microphone 2 of the mobile phone 1 shown in FIG.
2 is processed by a baseband unit 15, modulated into a transmission frequency band by a wireless unit 14, amplified and wirelessly transmitted to a partner terminal (not shown), and a signal from the partner is transmitted by the wireless unit 14. Received and demodulated, the baseband unit 15
, And is supplied to the speaker 23 for sound generation.

When returning from an outside place, the mobile phone 1 is normally set vertically in the slot of the charger 2 installed indoors so that its antenna faces upward, as shown in FIG. The power supply terminal pad portion 6 and the power supply terminal pin portion 8 come into contact with each other, and the data communication terminal pad portion 7 and the data communication terminal pin portion 9 come into contact with each other, so that the mobile phone 1 and the charger 2 are electrically connected. Is done. As a result, the battery 21 in the mobile phone 1, whose power has been consumed due to use at a place where the user is away from home, is charged via the power supply terminal pin portion 8 of the charger 2 and the power supply terminal pad portion 6 of the mobile phone 1.

Therefore, when data communication is desired, the portable terminal 3 is prepared in a state where the portable telephone 1 is set upright in the slot of the charger 2 for charging, and the portable terminal 3 is maintained. 2 optical transmitting / receiving unit 4 and portable terminal 3
The data communication is performed by operating the portable terminal 3 with the optical transmitting / receiving unit 5 facing the optical communication unit 5. At this time, the data input by the operator of the mobile terminal 3 is converted into an optical signal, received by the charger 4, and converted into an electric signal by the photoelectric conversion unit 13 in FIG. The data is input to the data communication terminal pad section 7 of the mobile phone 1 through the communication terminal pin section 9 and is further input to the data communication interface section 19, the control section 18, the baseband section 15, and the radio section 14 of FIG.
Is transmitted to a partner terminal (not shown) via a wireless line via the communication line.

A data signal from a partner terminal is received by the mobile phone 1 via a wireless line, demodulated by a wireless unit 14, furthermore a baseband unit 15, a control unit 18, a data communication interface unit 19 and a data communication terminal pad unit. 7 and a data communication terminal pin section 9 of the charger 2, the signal is input to the communication control section 12 of FIG. 2, and further converted into an optical signal by the photoelectric conversion section 13. Part 4
Light is transmitted to the optical transmission / reception unit 5 of the portable terminal 3.

At the time of this data communication, since the power supply terminal pad section 6 and the power supply terminal pin section 8 are connected, the battery 21 is charged. As described above, by performing data communication between the mobile phone 1 and the mobile terminal 3 via the charger 2 during charging, data communication can be easily performed without any special preparation for performing data communication. During the data communication, the battery 21 in the mobile phone 1 is always charged from the charger 2, so that even if the data communication is terminated and the mobile phone 1 is removed from the charger 2 and a call is immediately made, the battery 21 is used. You can talk without having to worry too much about available time.

Further, since the portable telephone 1 is provided with the pad section 7 for data communication in addition to the power supply terminal pad section 6 for supplying and charging power, most of the circuits of the existing portable telephone can be shared. In addition, the addition of a circuit for data communication is small, and the circuit configuration can be simplified as compared with a conventional mobile phone that uses a charging terminal for data communication.

Further, when the portable telephone 1 is set upright in the slot of the charger 2, data communication can be performed in the same form as that of a telephone call, that is, with the antenna standing almost vertically. Data communication can be performed with the best arrangement without being conscious of the installation state.

[0027]

As described above, according to the present invention,
A data communication function is provided in the charger, and a data communication terminal section is provided in the mobile phone and the charger so that optical communication is performed between the charger and the mobile terminal, so that data communication can be performed during charging of the mobile phone. is there. As a result, a call can be made while holding only the mobile phone while away from home or outdoors, and when returning from the outside and not used as a call, the mobile phone is normally set in the charger, and it is necessary to perform data communication in this state. In such a case, data communication can be easily performed only by installing a portable terminal within a range where optical communication with the charger is possible (operability of data communication can be improved).

Further, according to the present invention, by setting a portable telephone in the charger, data communication can be performed simultaneously with charging, so that charging can be performed during data communication. Thus, even when the mobile phone is disconnected from the charger immediately after the data communication is completed, the user can talk without worrying about the available time of the battery.

Further, according to the present invention, since the portable telephone is provided with the pad for data communication separately from the power supply terminal pad for supplying and charging power, most of the circuits of the existing portable telephone are provided. The circuit configuration can be simplified as compared with a conventional mobile phone that shares a charging terminal for data communication, and thus the mobile phone can be used as compared with the conventional mobile phone. The size and weight can be further reduced.

Further, according to the present invention, since the mobile phone is set upright in the slot of the charger, the installation state of the mobile phone can be set to the same state as during a call.
Data communication can be performed in the best installation state,
It is arranged in the best condition without the user having to pay special attention to the arrangement of the mobile phone.

Further, according to the present invention, the charger is provided with the optical transmission / reception means for data communication with the portable terminal, so that the portable telephone does not need to be provided with a connection connector. It is only necessary to provide a much smaller data communication terminal pad, and since the charger performs optical communication, the optical transmitter and receiver can be configured smaller and lighter than the case where a wired connection connector is provided,
Compared to a case where a wired connection connector is provided in the charger, the portable terminal can be installed at a desired position within a range where optical communication is possible without restriction of the connection cable, and the usability of the portable terminal can be improved.
