Description

[Detailed description of the invention]

0001

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic notebook having a wireless telephone function.

0002

2. Description of the Related Art Car phones and mobile phones are becoming popular as wireless telephone systems. In this wireless telephone system, a handset can move from one base station's service area (base station area) to another base station's service area while making a call. Alternatively, calls can be made and received from a car moving at high speed.

[0003] However, in order to realize such a function, the base station must always manage or know the current location of each slave unit. For this reason, the base stations must be connected to each other by computers, making the base station system complex and large-scale.

[0004] Furthermore, since the base station manages the slave units,
The number of slave units per base station is limited. Furthermore, in order to reliably achieve the above-mentioned functions, the transmission output of the handset must be relatively large, for example, 0.5 to 1W, which may shorten the battery life or increase the size and weight of the handset. I end up doing something like that.

[0005] In contrast to such wireless telephone systems, there is a telepoint system as a next generation wireless telephone system. Depending on the country, this may be PHP (Japan), C
It is called T-2 (Europe), DECT (America), etc.

[0006] In this telepoint system, the base station (telepoint base station) does not, in principle, manage slave units. Therefore, although it is possible to make calls from the handset, calls cannot be received to the handset. When an incoming call is required, the handset notifies the base station of the current location in advance by performing a predetermined key operation.

[0007] Furthermore, since the base station does not manage the handset, the handset cannot move from one base station's service area to another base station's service area while making a call; You can only move within the service area.

In other words, the telepoint system is similar to a wireless public telephone or a cordless telephone that can be carried over a wide range.

[0009] In the telepoint system, there are restrictions on the use of slave units, but since the base station does not have to manage the slave units in principle, it can be configured with only a transmitter/receiver and a switch, and the base station can be greatly simplified.

[0010] Furthermore, since the handset is used near the base station and is not used while moving between different service areas,
The transmission output of the handset can be reduced to, for example, 0.1 W, and therefore the battery life can be extended. Alternatively, the handset can be made smaller and lighter than a notebook.

[0011]

By the way, since the handset in the telepoint system can be made small and lightweight as described above, it is conceivable to combine the handset and the electronic notebook.

[0012] That is, when making a call, when you make a call, you search for the other party's telephone number using the telephone directory function (address book function) of the electronic notebook, and when the telephone number is displayed, press a predetermined key. The displayed phone number will be automatically dialed, and once the other party answers, you can make a normal call.

[0013] Therefore, not only the scope of use of the electronic notebook is expanded, but also the telephone can be easily and accurately made, making it convenient to use.

However, if the handset and electronic notebook are simply integrated, the battery will be wasted by the handset even when the phone function of the handset is not being used, shortening the battery life. turn into.

The present invention aims to solve these problems.

[0016]

[Means for Solving the Problems] Therefore, in the present invention, the reference numerals of each part correspond to the embodiments described below. 61 and the receiving circuit 62, the first contacts 71A to 7 supply external telephone number data.

Then, when the block 60 is set in the notebook body 10 and the plug 70 is inserted into the jack 30, the contacts 71A to 71N, 73, and 74 are connected to the contact 31A.
~31N, 33, and 34 are connected. Note that 72 is a dummy contact.

According to such a configuration, the power switch 2
2 is turned on, the processing of the CPU 11 starts from step 81 of the routine 80, then in step 82, each part is initialized, and then in step 8
3, a key input on the keyboard 14 is awaited.

Then, when a key input is performed, the process proceeds from step 83 to step 84, and this step 84
At , it is checked whether the key input requests a phone book function, and if the key input is a request for a phone book function, the process proceeds from step 84 to step 94.
In step 94, processing for the telephone directory is performed. In other words, type the other person's name on keyboard 1.
If you enter from 4, the person's phone number (and address, etc.)
The display data of is searched and taken out from the RAM 13,
This display data is supplied to the LCD 16 to display the other party's name and telephone number (and address, etc.).

When the process in step 94 is completed, the process of the CPU 11 returns to step 83.
It will wait for key input again.

If the key input in step 84 does not request the telephone directory function, the process proceeds from step 84 to step 85, where it is determined that the key input in step 83 requests execution of the telephone function. If it is not requested to perform the telephone function, the process proceeds from step 85 to step 95, where step 83
A requested function process, for example, a memo pad function, is executed by key input.

Furthermore, if step 95 is executed,
When the IC card 40 is set in the notebook main body 10, the functions of the IC card 40 can also be executed.

[0031] That is, the IC card 40 is connected to the notebook main body 10.

[0032] Therefore, the IC card 40 is
When set to 0, functions according to the program and data in the ROM 41 of this IC card 40,
For example, the function of a Japanese language dictionary is realized.

When the process in step 95 is completed, the process of the CPU 11 returns to step 83 and waits for a key input again.

Furthermore, the telephone block 60 is attached to the notebook main body 10.
If the telephone function is requested by key input in step 83, the telephone function is realized in steps 86 to 89.

That is, in this case, the name and telephone number of the person to be called is displayed in advance on the LCD 16 using the telephone directory function in step 94. Then, in step 83, among the keys on the keyboard 14, the execution key for the telephone function is operated.

Then, the process proceeds from step 83 through step 84 to step 85, but since the key input at step 83 indicates execution of a telephone function, the process proceeds from step 85 to step 86. Then, in step 86, the output of the CPU 11 is supplied as a control signal to the switch circuit 25 through the interface 26, and the switch circuit 25 is turned on.

Therefore, the voltage of the battery 21 is transmitted through the switch 22 → switch circuit 25 → contact 33 → contact 73 to the transmitting circuit 61, the receiving circuit 62, and the interface 66.
is supplied as its operating voltage, and these transmitting circuits 61 and receiving circuits 62 are brought into operation. Also, at this time, the bus 19 changes from buffer 24 to contacts 31A to 31N to contact 7.
1A to 71N are connected to the transmitting circuit 61 and the receiving circuit 62 through the signal line of the interface 66.

[0038] Subsequently, the processing of the CPU 11 proceeds to step 87, and in this step 87, processing for a telephone call is performed with the base station.

That is, the output of the CPU 11 permits the transmitting circuit 61 to transmit and the receiving circuit 62 to receive. The command signal from the CPU 11 is supplied from the CPU 11 to the transmission circuit 61 and transmitted to the base station through the uplink channel, and the command signal from the base station is received by the reception circuit 62 through the downlink channel.
It is supplied to U11. In this way, a predetermined command signal is accessed between the telephone block 60 (and the main body 10 of the notebook) and the base station, a calling protocol is executed, and a communication channel is opened between the telephone block 60 and the base station. .

Furthermore, the data of the telephone number of the other party displayed on the LCD 16 at this time is supplied from the RAM 13 to the transmitting circuit 61, and the DTMF signal of the telephone number, for example, is transmitted to the base station.

[0041] Then, the other party is called by this call, and when the other party answers the call, the other party's voice signal is transmitted to the receiving circuit 62.
is received by the receiver and supplied to the receiver 64, and its own voice signal from the transmitter 63 is supplied to the transmitting circuit 61 and transmitted. In this way, a conversation with the other party is made.

[0042] While this call is being made, the CP
The process of U11 proceeds from step 87 to step 88,
It is checked whether or not a key for ending a call among the keys on the keyboard 14 has been pressed, and if it has not been pressed, that is, when a call is in progress, step 88 is repeated.

However, when the call is ended and the end call key is pressed, this is detected in step 88 and the CPU 1
1 proceeds from step 88 to step 89, where switch circuit 25 is turned off and power is no longer supplied to telephone block 60.

The process of the CPU 11 then returns to step 83 and waits for the next key input.

[0045] Thus, according to the present invention, the notebook main body 1
By combining the telephone block 60 with the telephone block 60, the telephone block 60 can also be used as a handset of a wireless telephone system. In this case, especially according to the present invention, the switch circuit 25 is turned on and power is supplied to the telephone block 60 only when a telephone number is searched, and the power is turned off at the same time as the call ends.
