In FIG. 1.2, input from the keyboard 2.15.16 is processed by the keyboard encoder 8.21 in both the calculator and the telephone and is transmitted to the CPU 6.20. In addition, the display control of the display unit 3.17 is performed by the driver 3.
．． This is done via 25.

Further, read/write operations for the IC card 5 installed in the calculator or telephone are performed via a known interface circuit 9 for IC cards.

Each of the CPUs 6.20 and 20 has a built-in ROM that stores the programs shown in FIGS. 6 and 7.

The CPU 20 of the telephone further includes a built-in RAM that is used as a work area and the like. RAM7 on the calculator side
is shown independently of the CPU 6.

The telephone side is further provided with a line interface circuit 23 for controlling line connections. A telephone line NW is connected to a 0-line interface circuit 23, which includes an NCU, a ring tone sounding circuit, a ring signal detection circuit, a dial signal generation circuit, and the like.

Next, the operation of the above configuration will be explained.

The above-mentioned calculator and telephone read and write information to and from an IC card through the process shown in FIG. The process shown here is a process of registering a telephone number in association with a speed dial number, or searching for a target telephone number from a speed dial number.

That is, reading and writing to the IC card 5 (
registration) is DMA (direct memory access) processing (
The 0 indicator 3 (17) carried out by reference numeral 12) monitors the data written to or read from the card.

When registering a phone number, enter code 10 from keyboard 2 (15)
A speed dial number is entered as in , and this is the code 11.
It is converted into real address data in the memory of the IC card 5 by referring to the ROM table as shown in FIG. At the time of registration, telephone number data such as 13 is input, and this data is stored at the address indicated by the abbreviated number.

For reading, only the abbreviated number 10 is input, and the telephone number is similarly read from the real address in the memory of the IC card 5 determined by ROM table conversion. The read data can be displayed on the display 3 on the calculator side, and can be used directly for calling operations on the telephone side.

FIGS. 5A and 5B show the operating modes of the calculator. As shown, in the calculation mode of the calculator, the device performs known calculation operations using the keyboard 2 of FIG. This calculation operation includes known calculation processing such as four arithmetic operations and function operations.

On the other hand, by operating the read/write key 2A in FIG. 3, the IC card access mode can be entered, and by toggling the key 2A, either the read or write mode is selected. In the reading mode, by giving an abbreviated number from the arm keyboard 2 as described above, the corresponding telephone number can be read out and output to the display 3.

In the write mode, by giving the abbreviated number and telephone number data from the keyboard 2, the two are stored in the IC card 5 in association with each other.

FIG. 5(B) shows possible input keys in calculation and IC card modes, and number and character input mode switching in IC card access mode.

In calculation mode, use the numerical keys necessary for calculations, the four arithmetic operation keys,
Keys such as function operation keys can be manually operated. In the IC card access mode, a character input mode is provided for inputting names and the like. The character and number input modes can be alternately switched by operating the shift key 2B in the IC card access mode. In the numeric input mode, you can use the numeric keys and the + and - keys. In character input mode, in addition to each alphabet, you can input various symbols such as semicolons and colons.

Next, data processing in the above configuration will be explained in detail.

6(A) to 6(C) show the processing procedure of the CPU 5 of the calculator. In FIGS. 6(A) to 6(C), the locations marked with the same reference numerals are continuous at that position.

First, the CPU 6 determines whether the IC card mode is set in step S1. mode is IC
Not in card mode, i.e. read/write key 2A
If has not been operated, a known calculation operation is performed in step S2.

If step Sl is affirmative, the process moves to step S4, and it is checked whether the IC card 5 is set in the slot 4. Various known detection methods can be used to detect the IC card 5. If the IC card 5 is not loaded even though the IC card access mode is designated, a prompt prompting the user to load the IC card is displayed on the display 3 in step S3.

If the IC card 5 is set in step S4, the process moves to step S5, and the process moves to the IC card access mode. If nothing is specified, the read mode from the IC card is set.

In step S5, input from the dial key 20 of the keyboard 2 is detected. If this key human power is not available, see Figure 6 (B).
), the mode is determined again in the same manner as in step S1. If there is no input, the loop of steps S5 and S14 is repeated. Step 5
14, if the calculation mode is specified, step S2
to move to.

If there is an input in step S5, the input data is displayed on the display 3, and then in step S6 it is determined whether the input data is an input of an abbreviated number. In the case of inputting an abbreviated number, it is determined in step S7 whether the + or 1 key is input. Here, after entering the speed code, + or -
By pressing the key, the designated abbreviated number can be increased or decreased by 1.

That is, if the + or 1 key is pressed, the input abbreviated number is incremented or decremented by 1 in step S8. As a result, the displayed abbreviated number is also incremented or decremented.

In step S9, the telephone number and name data corresponding to the input abbreviated number are displayed on the display 3.

In step SIO, it is checked again as in step S1 whether the access mode of the IC card has been designated. If the calculation mode is designated, the process moves to step S2.

In step 311, it is checked whether the write mode for the IC card has been set. This process is performed by detecting the operation of the read/write key 2A. If the write mode has not been designated, the process returns to step S7 and the above search process using the abbreviated number is repeated.

On the other hand, if the writing mode is designated in step Sll, it is determined in step S12 whether or not the numeric input mode is designated. This identification is shown in Figure 5 (B).
This is done by detecting the operation of the shift key 2B as shown in connection with . In the case of numerical input, in step S13,
After storing the input numerical data in the address area of the memory of the IC card 5 corresponding to the abbreviated number specified in steps S8 and S9, the process returns to step S7.

On the other hand, if numeric input is not designated in step S12, the process moves to step S15 in FIG. 6(C), and the state of the shift key 2B is checked to determine whether character input mode is designated. If you are not in character input mode,
Returning to step S4, the abbreviated number is detected again.

If step 315 is affirmative, step 316 accepts the input of special character keys that can be input in the character input mode, and inputs the special character keys that can be input in the character input mode.
After storing it in the address area of the C card 5, step S7
Return to

As described above, in the IC card access mode, you can specify an abbreviated number, change it using + and n/a rake, and register data in the memory address of the IC card 5 corresponding to the input abbreviated number. Or you can read data from it.

In this way, the IC card 5 that has received data registration in association with the abbreviated number can be used by being attached to a telephone. Further, editing of data in the IC card 5 can also be performed on the telephone side.

FIGS. 7A to 7D show the processing procedure of the CPU 20 on the telephone side. It is assumed that the same reference numerals in each figure are consecutive in the same manner as above.

In FIG. 7(A), when the "RD" or rWRJ key is manually executed, the process proceeds to the next step 520, and in this step 520, the CPU 20 determines whether the IC card 5 is inserted into the slot 18. If the IC card 5 is not installed, a warning display prompting the IC card 5 to be installed is displayed in step S21 in the same manner as described above.

In the next loop of steps S22 and S23, input from the numeric keypad 15 used for dialing or other keys is detected. If no key force is detected, the process ends, but only if there is an input from the numeric keypad 15, the process moves to step 324. In other words, only numerical key inputs are accepted.

If there is a numerical value input, in step S24,
The input numerical value is recognized as an abbreviated number, and data is read from the memory address of the IC card 5 corresponding to the abbreviated number and displayed on the display 17.

In the following steps 325 and 326, the abbreviated number is incremented or decremented by inputting the + or - key, similarly to the calculator side.

The displayed data contents are also changed in accordance with the increment or decrement of the abbreviated number.

If neither the key nor the - key is input in Stella 7'S25, step 32 in FIG. 7(B) is performed.
Move to 7.

Steps S27, S28, and S30 are determination steps for identifying a change in read or write mode. Writing/reading is identified by the value of the WR (write) register. WR register is a CPU register,
It is set using a flag, RAM memory area, etc.

In step S27, it is determined whether the WR register is 1, that is, whether it is in the write mode. Step 330 in write mode, step 3 in read mode
28. In steps S28 and S30, input of the end key is checked. If the end key is used to specify the end of the process, the display is erased in steps S29 to S31" and the process is ended. In step S29, the WR
The RD register, which has the inverted contents of the register, is cleared. The RD register is used to indicate read mode.

If step 328 is negative, the process moves to step 53B in FIG. 7(D), and it is determined whether the # key in the numeric keypad 15 has been input? Find out. The # key is used as a command key to command a call to the currently displayed telephone number.

The # key is pressed with the handsera) 14B raised.

If the # key is pressed, in step S37, a dial signal corresponding to the displayed telephone number is transmitted to the line to call the other party's station.

When the call ends in step 338, the process returns to step S29 to end the process.

On the other hand, if step S30 is negative in the write mode, input of the dial key is detected in step S31. If there is no dial key input, the screen shown in Figure 7 (C
) The process moves to step 333. Step S31. S3
3 constitutes an input key determination step similar to steps 520 and 521 described above.

If the dial key manual operation is performed in step S31, step S25 and S are performed in step S32.
In step 26, the data that has been input and displayed at the specified address up to now is registered. On the other hand, step 3
In step S34, special keys that can be input are identified, and in step S35
Display only the data that can be entered in step 32.
Return to 5.

As described above, the registered data of the IC card 5 can be edited on the telephone side in the same way as on the calculator side, and the telephone number data registered on the IC card 5 can be called up using an abbreviated number and used for making a call. be able to. Of course, the correspondence between abbreviated numbers and telephone numbers or name data is the same as in calculators.

Therefore, the registration data of the telephone and the calculator can be shared, saving the input effort and making up for the limited memory capacity of each device by using the IC card. If a large amount of data storage is required, a large number of IC cards may be prepared.

Furthermore, even when a telephone or a calculator is shared by a large number of users, by having each person have their own IC card, they can freely use the device using abbreviated numbers without destroying the data registration of others.

Although a telephone and a calculator have been exemplified above, the present invention is not limited to these devices, but can be applied to various combinations of data processing devices and communication devices, such as electronic learning machines and facsimile machines.

Further, although an IC card is exemplified as a storage medium in the above, other media such as a magnetic disk, a magnetic bubble memory, an optical disk, and other storage media can be used.

[Effects of the Invention] As is clear from the above, according to the present invention, in a data processing system consisting of an electronic device that performs predetermined data processing and a communication device, a memory that can be attached to both the electronic device and the communication device is provided. Since a configuration is adopted in which data is shared between the electronic device and the communication device by installing a medium, the data of the electronic device and the communication device can be shared via the storage medium, saving the effort of data input. At the same time, it has the excellent effect of supplementing the storage capacity of the device.
