In this case, in the output mode, for example, by operating the classification key located at [1-1J, the sales amount of "Model A" in the first half of 1980 will be displayed on the display section 3. It is.

FIG. 3(d) shows a monthly schedule table used as a monthly schedule table.
Tuesday (Tu) Jr. Wednesday (We) Jr. Thursday (TI-
1) J r Friday (Fr) J [Saturday (Sa) J, in the classification key part of the matrix, for example, June 1985
It is the calendar assigned to the month. The operation of the above embodiment will be explained below by taking the input/output of the monthly schedule table shown in FIG. 3(d) as an example.

Figure 4 shows the data to be input into the monthly schedule for June 1985 shown in Figure 3(d) above.
Internal meeting on the 3rd at r2-2J position, 4th at r3-2J position
Indoor meeting on the 9th, golf competition on the 9th at N-3J position, r
On the 17th of 2-4J m, visitors from A company (from 900), visitors from company B (from 1100), new product announcement (from 1300) and review meeting (from 1600), softball on the 23rd at N-5J position. It shall be a tournament.

When inputting the schedule data as described above, first, as shown in FIG. 5(1), the rI10J key 4e of the key operator section 4 is operated to specify the input mode. The key output data in the key manual section 4 is stored in the counter 12.
The signal is sampled by the count value data from , is latched together with the count value data in the latch circuit 14 , and then input to the encoder 15 . The encoder 15 encodes the key code data of the r110J key 4e, which is the operation key, from the input key operation data (count value data and key output data), and stores it in the input buffer 16. rI10J*-4e stored in this human power buffer 716
When the key code data of C is input to the CPU 11,
P U 11 thereby inverts the contents of I10 mode register 11a of RAM 111 and sets the input mode. Along with this, the display control unit 25 causes the display unit 3 to display the characters rlJ indicating that the mode is input mode.

Next, in order to input and set the file name, refer to Figure 5 (2).
), when the rM/△" key 4f of the key control unit 4 is operated, the contents of the M/A mode register Ilb of the RAM 111 of the CPU 11 are inverted in the same way as in the case of the II/○" key 4e described above. Then, the alphabet specification mode is set. Along with this, the display control section 25 causes the display section 3 to display the characters rAJ indicating that the mode is the alphabet designation mode.

With this setting, the keyboard 6 will be in the Alphabella 1 to specification mode, and the classification key will be the alphabet key, so the actual file name rscH (JUNE)
J (meaning June schedule) is input by operating the classification key. When the classification key is operated, the process shown in FIG. The key operation signal and the count signal for key sampling output from the counter 13 are latched as matrix data in the latch circuit 18. Next, in step AO2, the M/A mode register 11
Depending on the contents of b, it is determined whether the current keyboard 6 is in the matrix designation mode or the alphabet designation mode. In this case, since the keyboard 6 is in the alphabet designation mode, the process advances to step AO3, and the data of rscH(JUNE)j is encoded from the latch circuit 18 via the encoder 15 according to the operation key, and then sent to the input buffer 16. , the process corresponding to the classification key operation ends. Then, when the file key 4d of the key manual section 4 is operated to instruct the completion of file name setting, the key code data of rscl-1(JUNE)J stored in the input buffer 16 is
File management block 21
For example, it is set as the file name of the second file "1", and the C register 253 of the display control unit 25 is set as the file name of the second file "1".
and displayed on the display section 3.

Next, as shown in FIG. 5(3), when the rM/AJ key 4f of the key input unit 4 is operated again to input actual data, the M/AJ key of the RAM 111 of the CPU 11 is
The contents of the A mode register 11b are inverted and the matrix designation mode is set, and at the same time, a switching signal is input to the memory area address designation section 17, and the memory area address designation section 17 becomes operational.

Subsequently, in order to designate a memory area, the user operates the "(June) 1st" classification key at the "r7-1" position on the keyboard 6, and the process shown in FIG. 6 is performed again. In this case, the key operation signal of the classification key at the r7-IJ position is input to the memory area address designator 17 and the latch circuit 18 in step AO1.

When the input signal is latched by the latch circuit 18, the process proceeds to step AO2, where the CPU 11 determines whether the current keyboard 6 is in the matrix designation mode based on the contents of the M/A mode register 11b. In this case, the keyboard 6 is in matrix specification mode, so
As a result of the determination, the process then proceeds to step AO4. Step AO
In step 4, it is determined whether the operated classification key is the same as the previously operated classification key, and since the previous classification key operation has not been performed yet, the judgment result is ""No," and the process then proceeds to step AO5. In this step AO5, the memory area address designation unit 17
The operation of the classification key at the position r7-1J on the keyboard 6 is determined from the signal from the counter 13 and the signal from the keyboard 6, and thereby the memory area at the position r7-1J is designated in the classification memory 19. This classification memory 1
9, under the control of the file management block 21, the file address designation section 20 selects the file name rscH among the files "0" to "19" in FIG.
(JUNE) Specifies the second file "1" in which J is set, so the record data in the memory area at the r7-I J position of file "1" is read/written by the read/write control unit 2.
2 is read out to the record memory 23. Step A
When the process of O5 is finished, next in step AO6,
r7 of the keyboard 6 latched by the latch circuit 18
- The key operation signal of the classification key in the 14th position is sent directly to the CPU.
As a result, the CPU 11 inputs the matrix data r7-IJ to the A register 251 of the display control section 25. Thereafter, the CPU 11 clears the record address register 241 of the record address designation unit 24 to rOJ as shown in step AO7, and then, in step AO8, the current time is input according to the contents of the I10 mode register lla of the RAM 111. Determine whether it is in the mode. In this case, since the I10 mode register 11a is in the input mode due to the operation of the r110J key 4e in FIG.

At this point, since there is no input data yet, the process proceeds to step A10, where it is determined whether or not there is record data in the record memory 23. Again, there is no record data yet, so next go to Stenbu△11.
Into the C register 253 of the display control unit 25, code data of the character "?" indicating that no record data has been input and the current operation of the classification key is invalid is input. Next, in step A12, the value of the record address register 241 is input to the B register 252 of the display control section 25. In this case, since the value of the record address register 241 is rOJ, "0" is input to the B register 252.

In this way, A register 251, B register 252, C
When the input to the register 253 is completed, the following step A1
3, the A register 251, the B register 252,
The display control unit 2 uses the data held in the C register 253.
5 is the matrix data in the memory area [7-14, the number of items data rOJ and the character "?" indicating that record data has not been input, and the character rM indicating the matrix specification mode.
J and the characters rlNJ indicating the input mode are displayed on the display unit 3, and the processing for the operation of the classification key is thus completed.

Then, the character r? indicates that the record data displayed on the display section 3 has not been input yet. After operating the rM/AJ key 4f to enter the alphabet designation mode as shown in FIG.
Key-operate KA IG IJ as record data,
When input, this key operation signal is first latched in the latch circuit 18 in step AOI, and then in step A, similar to the rSCH(JUNE)J data in FIG. 5(2) above.
After it is determined in O2 that the alphabet designation mode is selected, in step 803, input buffer ? 1
6 is stored. Next, operate the rM/AJ key 4f again to enter the matrix specification mode, and press r on the keyboard 6.
When the classification key "(June) 1st" at the position 7-1J is operated, the key operation signal of the classification key at the "r7-1" position is input to the memory area address designation unit 17 and the latch circuit 18 in step AO1. . Then, after it is determined in step AO2 that the mode is matrix specification mode, step A
At O4, it is determined whether the classification key at position r7=1J, which is an operation key on the keyboard 6, is the same as the classification key operated last time. Here, the classification key operated last time is the same as the current classification key r7-IJ, but no data was written during the previous classification key operation, and the classification key operation is treated as invalid. in this case,
It is determined that they are not the same, and the process then proceeds to step AO5.

In step AO5, the record data in the storage area r7-IJ corresponding to the operated classification key is read into the record memory 23 by the read/write section 22.

Next, in step AO6, the matrix data r7-1J is input to the A register 251 of the display control section 25, and then, in step AO7, the record address register 241 of the record address designation section 24 is cleared to "0". Then, in the following step AO8, it is determined that the current time is the input mode based on the contents of the I10 mode register 11a of the RAM 111, and then in step AO9, when it is determined that the input data is in the input buffer 16, the process proceeds to the following step A1.
In step 4, the input data is written.

FIG. 7 shows a subroutine for this input data writing process.
As shown in 301, the specified file at that point is
The CPU 11 determines whether the file is a file or not based on the output of the file management block 21. Here, r set J
Since it is not a file, the process proceeds to step BO2, and the record address register 24 in the record memory 23 is
Write input data to the area specified by 1. here,
Since the contents of the record address register 241 are rOJ in step AO7 in FIG. It is written as "0", that is, in the highest position. Thereafter, in step 803, the contents of the record memory 23 are written by the read/write control section 22 to the locations specified by the file address specification section and the memory area address specification section 17 of the classification memory 19, and the input data The write process ends. Here, since the address specified in the file address designation section and the memory area address designation section 17 is the file address "1j1 memory area address r7-IJ," the data will be written to this address position.

Note that if it is determined in step BO1 above that the specified file at that point is an r-located J file,
The input data stored in the input buffer 16 is
The P U 11 sorts and inputs alphabetical characters into the record memory 23, and then, in step 803, the contents of the record memory 23 are stored in the classification memory 1.
Write to the specified address location of 9.

After completing the subroutine for writing input data in step A14, the contents of the record address register 241 are updated by "+1" in step A15. Subsequently, in the next step A12, the value "1" of the record address register 241 that has been updated is set to
Input to B register 252. Finally, in step A13, the display control unit 25 uses the data held in the A register 251, B register 252, and C register 253 to display the matrix data r7-1J, the number of items data "1", and the input data rsYo in the memory area. -I IN-KA I
G JJ is displayed on the display section 3 together with the characters rMJ indicating the matrix designation mode and the characters rINJ indicating the input mode, and the process ends here.

Next, in step AO2, it is determined that the mode is matrix designation mode, and the process proceeds to step AO4, where it is determined whether or not the operated classification key is the same as the previously operated classification key. It is determined that the classification key operated here is not the same as the one operated last time, and in the next step AO5, the file address designation section 2 of the classification memory 19
0 and the record data in the memory area addressed by the memory address designating section 17 are read into the record memory 23 by the read/write control section 22 . Here, the file address specifying unit 20 selects the rSC)- of the second file "1" by the key operation in FIG.
1 (JIJNE)J, and the memory address specification section 17 specifies the record data in the memory area at the r2-2J position by operating the classification key, so the classification memory 19 specifies the record data written in that memory area. Only the record data rBUNA r-KA IG IJ stored in the record memory 23 is read/written by the read/write control unit 22.
is read out. Thereafter, in step AO6, the classification key matrix data r2-2j latched in the latch circuit 18 in step AO1 is transferred to the A register 251 of the display control unit 25.
is input. Then, in the following step AO7, the record address register 241 of the record address designation section 24
is cleared, then in step AO8 RAM 1
Based on the contents of the I10 mode register 11a of No. 11, it is determined whether or not it is the input mode. Here, the above 8th
Since the output mode has been set by operating the r110J key 4e in FIG. (1), the result of the determination is that it is not the input mode, and the process then proceeds to step A17. In this step A17, it is determined whether or not there is input data. In this case, there is only a classification key operation for specifying the position of the memory area, and there is no input data, so the process proceeds to step A18, and the record memory 23 Record data rBUNA I-KA IGI specified in the record address register 241 of the record address designation section 24 from
J is input to the C register 253 of the display control section 25. Thereafter, in step A19, the record address register 241 of the record address designation section 24 is used to display the number of items.
The value "1" obtained by r+1J to the content "0" is input and set to the 8 register 252 of the display control unit 25 as the number of items data. Then, when the process of step A19 is completed,
Next, in step A13, the A register 2 of the display control section 25
51, the matrix data r2-2J, the number of items data "1", and the record data r8LINAI-KArGIJ input into the B register 252 and C register 253, 71- the letter "M" indicating the lix specification mode, the letter rOUTJ indicating the output mode This r2-2J is also displayed on the display unit 3.
The processing for the position classification key operation ends.

Next, as shown in FIG. 8 (4), if you operate the classification key at the r4-2J position corresponding to "(June) 5th" on the keyboard 6, the first step in response to this key operation is as shown in FIG. A
After the matrix data r4-2J of the classification key operated by OI is latched in the latch circuit 18, steps AO2 and AO
The read/write control section 22 reads out the record data in the memory area specified in step AO5 via step AO5. Here, r4-2 of rscH(JUNE)J of the second file "1" of the classification memory 19
Since no record data has been input to the memory area at the J position, the read/write control unit 22 cannot read data, and no record data is written to the record memory 23.

Thereafter, in step AOf3, the matrix data r4-2J latched by the latch circuit 18 is written to the A register 251 of the display control section 25, and in step AO7, the contents of the record address register 241 of the record address designation section 24 are cleared. After that, it is determined in step AO8 that the input mode is not in effect, and the process proceeds to step A17. If it is determined in step A17 that no data has been input other than specifying the location of the memory area, then step A18
The contents of the record address register 241 rOJ
Accordingly, the corresponding record data is read from the record memory 23 and written to the C register 253 of the display control section 25. In this case, since there is no corresponding data in the record memory 23, the CPU 11 instead prints the letter r? indicating that there is no input data. The key code data of J will be written to the C register 253. After that, step A19
In step A13, the value "1" obtained by r+IJ to the content "0" of the record address register 241 of the record address specifying section 24 is input and set as the item number data to the 8 register 252 of the display control section 25. The matrix data r4-2j, the number of items data "1", and the record data "?" input to the register 251, B register 252, and C register 253 are displayed on the representation section 3, and the classification of the rA-2J position on the keyboard 6 is displayed. Ends processing for key operations.

Similarly, as shown in FIG. 8(5) and FIG. 8(6), the N-3J position corresponding to "(June) 9th" and "(June) 17th" on the keyboard 6, r2 rl-3J of the second file "1" of the classification memory 19 by operating the classification key at the -44 position.
Record data from the memory area at position r2-4J, rGOLF-CONPEJ, rA-8HARA rK
YAKU (900~)" is matrix data N-3J, r
Each of A-2J and the item number data "1" are displayed on the display section 3.

Next, as shown in FIG. 8 (7), when the classification key at position r2-4J corresponding to "(June) 17th" on the keyboard 6 is operated again, steps AOI and AO2 are performed, and step A
At O3, it is determined that this operation classification key is the same as the previous operation classification key in FIG. 8 (6), and then step A16
Proceed to. In this step A1G, I1 of RAM 111
If it is determined that the current mode is not the input mode but the output mode based on the contents of the 0 mode register 11a, the process proceeds to step A20.

In this step A20, as in step A17 above, it is determined whether or not there is any data input other than the designation of the location of the memory area.Since no data has been input here, the process proceeds to step A21.

In step A21, the contents of the record address register 241 of the record address designation section 24 are updated by "+1" in response to the operation of the classification key at the same position.Here, the contents of the record address register 241 are r
Since it was OJ, "1" is newly set. After this, record data rB-8HA RAIKYAKtJ (1100
~)” is input to the C register 253 of the display control unit 25. Next, in step A19, the value "2" obtained by adding "+1" to the content "1" in the record address register 241 is input to the 8 register 252 of the display control section 25, and finally, in step A13, the A register 251 of the display control section 25, The matrix data r4-2J, the number of items data r2J, and the record data rB-8HA RALKYA (1100~) input into the B register 252 and the C register 253 are displayed on the display section 3, and the second rA-2 of this keyboard 6 is displayed.
The processing for the classification key operation at the J position ends.

After that, as shown in FIG. 8 (8) and FIG. 8 (9), when the classification key at the r2-4J position corresponding to "(June) 17th" on the keyboard 6 is operated again, the above-mentioned Figure 8 (
In the same way as in case 7), the contents of the record address register 241 of the record address designation section 24 are sequentially changed to "+1".
The update setting is performed, and accordingly, the record data l5)-IINSE IHIN-HAPPYO(13) located at the record addresses "2" and "3" in the record memory 23
00~)", rHANsE I-KA I (1600
~)'' are read out one after another and displayed on the display unit 3 along with the matrix data r4-24 and the item number data “2” and “3”.

Next, as shown in Figure 8 (10), once rM/A
After operating the J key 4f to enter the alphabet specification mode and operating the classification key corresponding to the letter "S" on the keyboard 6, use the rM/AJ key 4" again to set the matrix specification mode, and then press the keyboard 6 " (June) 17th”
When you operate the classification key at position r2-44, which corresponds to
An initial search is performed for the record data of the initial letter "S" in the memory area at the r2-4J position of the file address "1" in the classified memory 19 corresponding to "June 17th". That is, in response to the operation of the classification key corresponding to the letter "S" on the keyboard 6 in the initial alphabet designation mode, alphabetical input processing for the letter "S" is performed in step AO3 via steps AO1 and AO2. Remember. Then, in response to the operation of the classification key at the r2-4J position corresponding to "(June) 17th" on the keyboard 6 in the next matrix specification mode, this operation classification is performed in step AO4 via steps AOI and AO2. It is determined that the key is the classification key at the r2-4J position, which is the same as the operation classification key in the previous 71-RIX designation mode shown in FIG. 8(9), and the process proceeds to step A16. After it is determined in step A16 that the mode is not the input mode, it is determined in step A20 whether or not there is input data other than memory area designation in the matrix designation mode. Here, it is determined that there is input data due to the operation of the classification key corresponding to the 60 character "S" on the keyboard in the alphabet designation mode, and the process then proceeds to step A22. In this step A22, in order to initialize the contents of the record address register 241 of the record address specifying section 24, the contents of the record address register 241 of the record address specifying section 24 are cleared in the same manner as in step AO7, and the clearing process of the record address register 241 is completed. Then, proceed to step A23. In this step A23, the data of the character stored by operating the classification key in the alphabet designation mode and the data of the first letter of the record data of the record address of the record memory 23 specified by the record address register 241 of the record address designation section 24 are combined. are compared by the data comparison unit 113 of the CPU 11, and it is determined in the next step A24 whether or not the two data match as a result of the comparison. In this case, the input character data in the alphabet designation mode is "s", and the record data rA-8HA RAIKYAKU (900
Since the initial data of "~)" is rAJ, it is determined that the two data do not match as a result of the comparison, and the process then proceeds to step A25. In step A25, it is determined whether there is no record data at the address position specified by the record address register 241. Here, since the record data rA-8HA RAIKYAKU (900~)J has been input, the judgment result is "no", and then in step A26, the content rOJ of the record address register 241 is updated by "+1" and "1'' and the process returns to step A23. In this way, this step A23-A2
6 is repeated, and when the contents of the record address register 241 are set to "2" at the second step A26, the input character data "s" in the alphabet specification mode and the record address register 241 are set at the subsequent step A23. Specified record data rsHlN5E IH
IN-HAPPYO (1300~)” initial letter data “
S'' is compared. If it is determined in the subsequent step A24 that the two data match as a result of the comparison, the process then proceeds to step A18, where the record data rSHl specified by the record address register 241 is used as the corresponding data.
N5E IHIN-HAPPYO (1300~)” is input to the C register 253 of the display control section 25. After that, in step A19, the value "3" is obtained by adding r+1J to the content "2" of the record address register 241 to display the number of items.
is stored as item number data in the B register 25 of the display control unit 25.
2, in step △13, the display control unit 2
Matrix data r2-44 input to A register 251, B register 252, and C register 253 of 5, item number data "3" and record data rsHlN5E IHI
N-) (APPYO (1300~), the letter "M" indicating the matrix specification mode, the letter rO indicating the output mode
This is displayed on the display unit 3 along with UTJ, and the initial search process for this r2-4J position is completed.

Although not used here, the above step A17
If it is determined that there is input data, that is, instead of inputting the initial letter at the r2-4J position where the memory area was previously specified as shown in Figure 8 (10), another memory area is newly specified. In this case, even if it is determined that an initial letter has been input, the initial search operations of steps A23 to A26 are performed.

Furthermore, if it is determined in step A25 that there is no record data corresponding to the initial letter when executing the initial search in steps A23 to A26, it means that the input of the initial letter or the specification of the memory area location is incorrect.
An error message is displayed on the display unit 3.
