【Example】

Example 1. An embodiment of the present invention will be described below with reference to FIGS.
Will be described. In FIG. 1, reference numeral 1 is a main body of a portable telephone such as a handheld portable telephone handset, 1A is its housing, 2a is its antenna, 3a is a radio / high frequency circuit, 4 is a modulator / demodulator and data for performing time division multiplexing processing. A processing unit, 5a is a control unit, 6a is a memory unit for storing dial data and the like, 7 is an optical / electrical signal conversion unit, 8 is a light receiver, 9a is a window through which an optical signal is passed, 10 is an analog voice signal / A voice processing unit for digital conversion and encoding / decoding, 11 is a receiver, 12 is a microphone, 13a is a display unit for displaying dial numbers, and 14a is an external communication terminal device such as a pager terminal device. The slide groove 15a for this is an input operation unit such as a ten-key pad.

On the other hand, 16 is an external communication terminal device such as a pager terminal, 16B is its housing, 17 is a light emitting device for transmitting an optical signal, 18 is an amplifier circuit, and 19 is a sounder for emitting an incoming call notification sound. is there. Other blocks having the same numbers and suffixes b are blocks having the same functions as the same numbers of the mobile phone body 1.

Next, the operation will be described. Pager 16
When the wireless call signal is received from the base station from the antenna 2b having the built-in wireless call signal, the wireless call signal is demodulated by the wireless circuit 3b and sent to the control unit 5b. First, the control unit 5b sends a notification signal to the amplifier circuit to notify the user that an incoming call has arrived.
Ring 9.

When the caller's dial number data sent by a radio signal from the base station is received, the display unit 1
The dial number is displayed on 3b and the dial number data is written in the memory 6b. Then, the pager 16 is fitted into the mobile phone 1 using the guide grooves 14a and 14b. Since optical signal communication takes only a short time, there is no problem even if the guide grooves 14a and 14b do not have a lock mechanism. When fitted to the bottom, the windows for optical communication on both sides are aligned. When a transmission operation of dial number data is performed from the input operation unit 15b in that state, the control unit 5b reads the dial number data stored in the memory 6b, encodes and transmits it to the light emitter 17. The light emitter 17 converts this data into an optical signal and transmits it through the window 9b.

A pager window 9 is also provided on the side of the portable telephone body 1.
A window 9a is provided at a position in contact with b, and the transmitted optical signal enters the light receiver 8 through this window 9a. In this way, communication between the two is performed without contact. This window is fixed to the housing,
Alternatively, since it is integrally molded, there is no risk of water droplets entering inside even when used in the rain. In addition, the guide groove 14
When they are fitted together using a and 14b, both windows are in a close contact positional relationship, so even if some water drops or dirt adheres to the windows, data transmission by optical communication is possible without a problem with just wiping with a fingertip. .

Since the data transmission method according to the present invention is one-way from the pager side to the portable telephone, the control unit 5b on the transmission side confirms whether or not the control unit 5a on the reception side can correctly receive the data. If there is no hand, but the dial number is received, the dial number is displayed on the display unit 13a so that it can be confirmed. If it cannot be received normally, it is not displayed, and the user may operate the input operation unit 15b of the pager 16 again to transmit dial data.

Although it is a certain method to perform the optical communication data transmission after fitting into the guide grooves 14a and 14b as described above, the light of the light emitter 17 is received even if they are separated. Dial data can be transmitted within the range that the device 8 can reach. When it is difficult to fit the guide groove into the guide groove one by one, the same effect can be obtained even if the above operation is performed while the guide groove is separated.

The portable telephone 1 which has received the dial number data by the light receiver 8 first sends an interrupt signal for transmitting the data from the optical / electrical signal converter 7 to the controller 5a. The control unit 5a returns an enable signal when the standby state for data is adjusted. When the enable signal is returned, the optical / electrical signal converter 7 converts the data received by optical communication into an electric signal and transmits the electric signal to the controller 5a. The control unit 5a writes the received dial number data in the memory 6a. After that, when a call operation is performed from the input operation unit 15a, the stored dial number data is read from the memory 6a and written in the RAM in the control unit, and the telephone number is displayed on the display unit 13a. Furthermore, when a dial transmission operation is performed, the data processing unit 4 and the wireless circuit unit 3 are activated,
Dialing is performed according to the dial number data read from the RAM.

Example 2. In the first embodiment, the case where the pager terminal 16 is connected to the mobile phone body 1 has been described, but in this embodiment, the case where the electronic dialer device is connected will be described. FIG. 3 is a block diagram showing its configuration, and 21 is an electronic dialer device. 5c is a control unit, 6
c is a memory unit for storing dial data, 9c
Is a window for transmitting an optical signal, 13c is a display unit for displaying a dial number, 14c is a guide groove for fitting in a mobile phone, 15c is an input operation unit, 17 is a light emitting device for transmitting an optical signal, and 18 is an amplifier circuit. , 19 are speakers for transmitting DTMF sound.

In a normal dialer device, a DTMF sound corresponding to a dial number is transmitted in a state where the speaker 19 is closely attached to the transmitter of the telephone, and the dial transmission is performed by transmitting the sound to the exchange. In addition to this, in the present invention, data transmission means by optical communication is provided. To explain the operation, the dial data of the other party required by the user is registered in advance from the input operation unit 15c. The control unit 5c writes the data of the other party's name and dial number in the memory 6c according to the registration operation. When making a call, first, the dialing number of the person to be called is called. The control unit 5c reads out the instructed data from the memory 6c, writes it in the internal RAM, and displays the name and dial number on the display unit 13c. At the latest, the guide grooves 14a, 1 are formed on the mobile phone 1
The dial number data is transmitted in a state in which the windows 9a and 9c are aligned and in close contact with each other. The control unit 5c reads dial number data from its own RAM, encodes it to the light emitter 17, and transmits it. The data is transmitted as an optical signal to the portable telephone body 1 side through the window 9c.

On the side of the portable telephone main body 1, an optical signal is incident on the light receiver 8 through the window 9a. In this way, communication between the two is performed without contact. Since the windows 9a and 9c are fixedly attached to the housing or integrally formed, there is no fear of water droplets entering the inside even when used in the rain. In addition, the guide grooves 14a, 14
When they are fitted together using c, the windows 9a and 9c are in close contact with each other, so that even if some water droplets or stains are attached to the windows, data transmission by optical communication is possible without having to wipe them with a fingertip. is there.

Since the data transmission system according to the present invention is one-way from the electronic dialer side to the portable telephone, the control unit 5c on the transmission side confirms whether or not the control unit 5a on the reception side can correctly receive the data. There is no hand,
When it can be received, the dial number is displayed on the display unit 13a so that it can be confirmed. If it is not received normally, it is not displayed. Therefore, the user may operate the input operation unit 15c of the electronic dialer 21 again to transmit the dial data.

Furthermore, as described above, the guide grooves 14a,
A reliable method is to carry out optical communication data transmission after fitting into c, but even if they are separated, the light emitting device 1
Dial data can be transmitted as long as the light of 7 reaches the light receiver 8. When it is difficult to fit the guide groove into the guide groove one by one, the same effect can be obtained even if the above operation is performed with the guide groove separated.

The portable telephone 1 having received the dial number data by the light receiver 8 is converted into an electric signal by the optical / electrical signal converter 7 and transmitted to the controller 5a. The control unit writes the received dial number data in the memory 6a. After that, when a calling operation is performed from the input operation unit 15a, the stored dial number data is read from the memory 6a and the telephone number is displayed on the display unit 13a. Further, when a dial transmission operation is performed, the data processing unit 4 and the wireless circuit unit 3a are activated, and the dial transmission is performed according to the read dial number data. By the way, although the amplifier circuit 18 and the speaker 19 for transmitting the DTMF sound are provided in FIG. 3, these are not necessary if the option is dedicated to the portable telephone with the optical communication function.

Example 3. In the above-described embodiments, the lock mechanism is not provided in the guide groove of the mobile phone body 1 and the external communication terminal device fitted with the same, but a lock mechanism may be provided. In this case, as shown in FIG. 4, the lock mechanism 2 is provided on both the mobile phone body 1 and the external communication terminal device.
Switches 23a and 23b interlocking with 2a and 22b are provided, and when they are fitted until they are locked, the respective control units 5
The detection signals are sent to a and 5b. When the lock detection signal is input, the control unit 5b on the external communication terminal device side reads the latest dial number data stored in the memory 6b and transmits it to the light emitter 17. The data is received by the light receiver 8 on the side of the mobile phone body 1 through the windows 9a and 9b by optical communication, and is converted into an electric signal by the photoelectric conversion unit 7 and transmitted to the control unit 5a. When the lock detection signal from the lock switch 23a is input, the control unit enters the data standby state from the photoelectric conversion unit 7 and waits for the input of data. When it is received, it is written in the memory 6a.
Further, when a dial transmission operation is performed, the data processing unit 4 and the wireless circuit unit 3 are activated and dial transmission is performed in accordance with the read dial number data.

As described above, according to the embodiment of the present invention, the data transmission between the portable telephone main body and the external communication terminal device is performed by the optical signal transmission system, so that the transmission portion is simple by providing the window. The structure is sufficient, and a waterproof and drip-proof structure can be easily realized. Can be used without danger of short circuit even when used in the rain. Since the guide groove is provided for the fitting, there is an effect that the window portion can be surely aligned and data can be transmitted quickly. Since data transmission only needs to allow light to pass through, there is no need for precise fitting as in the case of an electrical contact connector, and the structure of the fitting guide groove is simple. Since there are no exposed contacts, problems such as damage and corrosion do not occur, and defects can be greatly reduced. Further, since it is an optical transmission system, it is possible to communicate even if it is separated.

As described above, a user of a portable mobile phone (PHS) or a mobile phone, who carries with him anywhere and anytime, can call the person who called the pager speedily when he / she makes a call to the pager. You can make up for the inability to receive calls when you are in the zone.

When an electronic dialer is used as the external communication terminal device, if a complicated display for electronic telephone directory function and kana display is provided on the electronic dialer side, the memory on the portable telephone body side has a small capacity. Since the display is a 7-segment type that displays dial numbers, it is advantageous in terms of cost reduction and downsizing. By making the electronic phonebook function an option only for users who need it, a wider range of usages can be provided.

If a lock mechanism is provided in the guide groove for fitting the portable telephone body and the external communication terminal device, the structure will be a little complicated, but it can be used even in an integrated state, and data transmission by optical communication can be surely performed. The property is improved. further,
By providing the switch for detecting the lock, it becomes possible to automatically transmit the data from the external communication terminal device to the main body of the mobile phone, which is more convenient.
