Furthermore, the hands-free device 4 is provided with a speaker 41 and a microphone 42.

In such a car telephone device, it is possible to make and receive calls using the control unit 2, and it is also possible to make calls using the hands-free device 4t.

[Problems with background technology]

According to such conventional car phone devices, calls can be made using a handset (including a speaker and a microphone 25T) or a hands-free device 4T-, but if only the driver's calls are considered, hands-free is not possible from a safety standpoint. Device 4
It is desired to use it. In this case, the conventional car telephone device, which requires unnecessary configurations such as a handset included in the control unit 2, has the disadvantage that the device becomes complicated and large.

[Purpose of the invention]

The present invention was made in view of the above-mentioned shortcomings of the conventional car phone device, and its purpose is to provide a simple and compact car phone device that can provide sufficient functions as a car phone device when configuring the car phone device. It is an object of the present invention to provide a transceiver unit for a car telephone device that can constitute a car phone device.

[Summary of the invention]

Therefore, in the present invention, a receiving section that receives at least a voice signal and a calling signal, a transmitting section that transmits at least a voice signal and a dialing signal, and the above-mentioned receiving section and the above-mentioned transmitting section are controlled. and a connector connected to a data processing device having a key input section including at least a numeric keypad for inputting dial data. The present invention constitutes a transceiver unit for a telephone device and achieves the above object.

[Embodiments of the invention]

FIG. 1 is a block diagram of a car phone device constructed using a car phone transceiver unit according to an embodiment of the present invention. This car telephone device also includes a transceiver unit lOO, a personal computer 5, and a vans device 4.

The transceiver unit 100 includes a transmitter circuit 101, a receiver circuit 102, a control circuit 103, and a synthesizer circuit 1.
04, a common unit 105, which is equipped with a controller unit connector 106, amplifiers 107 and 108, and a personal computer connector 109;
The personal computer 5 is equipped with a display 51, a keyboard 52, a control circuit 53, and a connector 54.

Connector 109 and connector U are connecting cable 6
A portion of the connection cable 6 extending from the connector 109 is connected to the hands-free device 4 .

The personal computer 5 is of a so-called hunt belt type, can be driven by a battery, and is portable. The keyboard 52 is provided with a numeric keypad for dial input, a # key, an X key, and the like. The display 51 is capable of displaying at least 10 digits of numbers and symbols. The control circuit 53 has the configuration of a microcombimeter, and in addition to the functions of a normal personal computer,
It has the functions of an input section (such as a dial keypad) and a display section as a telephone of a car telephone device by loading a program into the RAM from a floppy disk or the like. Specifically, the control circuitry includes a keyboard 52
In addition to transmitting dial data etc. input from the connector 54 via the connector 54, a dial number based on this dial data is displayed on the display 51. Further, the control circuit 53 stores, for example, previously sent dial data, and by a predetermined operation of the keyboard 52, displays a dial number based on the previously sent dial data on the display 51.
It has the functions of multi-function telephones that have recently appeared.

Further, the control circuit 103 of the transceiver unit 100 has a microphone configured as a computer, and controls each part as follows. When dial data is sent through the connector 109'i, the control circuit 103 performs 1. Transmission circuit 101 controls the synthesizer circuit 104 and sends out a corresponding dial signal from the transmission circuit 101. The sent dial signal is sent to the duplexer 105 and the antenna 200t.
- transmitted to the station via Also, the antenna 200 from the station
The paging signal that has arrived via the duplexer 105 reaches the receiving circuit 102, from which the incoming data is sent to the control circuit 103. The control circuit 103 is the receiving circuit 10
2 to control the bell signal to the amplifier 107 and the connector 10
9, is sent to the speaker 41 of the hands-free device 4 via the cable 6.

Accordingly, the speaker 41 outputs a ringtone. In order to respond to this, a predetermined key on the keyboard 52 is operated to send data corresponding to off-hook from the control circuit 53 to the control circuit 103, and a K is sent to enter a talking state.

When a call is made due to an outgoing or incoming call, the control circuit 10
3 controls the transmission circuit 1011, the reception circuit 102, and the synthesizer circuit 104t to switch between transmission and reception. As a result, the audio signal sent out from the microphone 42 is =
The audio signal reaches the transmission circuit 101 via the connector 109 and the amplifier 108, and is transmitted from there via the duplexer 105 and the antenna 200. On the other hand, the audio signal received via the antenna 200 is transmitted via the duplexer 105. The signal reaches the receiving circuit 102 and is sent from there through the amplifier 107 and the connector 109 to the speaker 41, through which the voice of the other party can be heard. Further, the connector 106K can be connected to a control unit similar to the control unit 2 shown in FIG. 2, or a control unit obtained by removing the amplifiers 26, 27t from the control unit 2 shown in FIG. When such a control unit and the personal computer 5 are connected,
Which one to give priority to is determined in advance by the system, or by key operations on either the keyboard 52 or the keyboard 22.

With the car telephone device configured as described above, the driver can safely make calls using the personal computer 5 and the hands-free device 4 while driving. According to the embodiment, the hand belt type personal computer 5 is not only used at a company or home, but also
It is carried and used on the go. Meanwhile, it is used in cars as part of a car telephone system. For this reason, the user must
By purchasing the Lee device 4, the personal computer 5 can be used as a normal personal computer and as a car telephone device.

In the embodiment, the personal computer 5t is connected to the transceiver unit 100, but any data processing device having at least a key input section including a numeric keypad may be used.
It may also be something like an electronic desktop calculator. In this case, the data processing device includes the personal computer 5 shown in FIG.
It is assumed that the control circuit 53 has a starting function.

Furthermore, at present, automobiles are equipped with data geography devices (computers) that perform engine fuel injection control, anti-lock brake control, suspension warning control, and drowsy driving prevention control while driving. However, in the future, it is conceivable that such data processing devices will be provided with control and processing functions according to the will of the driver. For this purpose, if a data processing device is equipped with a port or the like and a program for control processing can be inputted, such a data processing device can be used instead of the personal computer 5.
It is also possible to use tr. Also, the amplifier 107.
108 is not necessarily required and can be included in the hands-free device 4.

〔Effect of the invention〕

As explained above, according to the present invention, as long as the device of the present invention is provided, it is possible to provide necessary and sufficient functions when configuring a car telephone device, and there is no unnecessary configuration.
It is most suitable for constructing a simple and compact car telephone device. Moreover, since the data processing device that the user has can be utilized, there is no waste in the configuration, and it is possible to construct an inexpensive car telephone device.
