A register 58 and a cursor position register 59 for specifying the position of the cursor 40a on the display 11 are provided.

Based on the operation of the print key 36, the CPLI 50 transfers the character data in the line buffer section 54 to the print buffer section 75.
7 for printing by the line printing device 8, and transfers the character data in the auxiliary buffer section 55 to the beginning of the line buffer section 54, and also transfers the character data from the line buffer 1 section 54 to the display buffer j.56. Furthermore, when the character data in the line buffer section 54 is deleted by operating the delete key 45, the CPU 50 displays the character data after the deleted part as an auxiliary buffer. The deleted data, including the part 55, is moved in the -C upper direction by the number of llJ.

Next, according to Figures 4 to 8, this E1 edict printing age will be explained. Now, this Japanese printing device (15
When the power is turned on by the C1 power switch 7, the second
As shown in the figure, a triangular head-of-line symbol 60 is displayed on the leftmost first digit of the display '11, and a cursor 40a is displayed on the second digit. Further, the guidance 401) displays "Hiragana" behind the mode display characters 41, indicating that the Kana input mode has been automatically set.

In this state, kana character keys 12 to 2 on the keyboard 10
When character data is input using the first selection operation, the CPU
50, the data is stored in the input buffer 53 of the RAM 52 (j) sequentially from the beginning in the buffer section 54, and is transferred from the row buffer section 54 to the display buffer 56 to be displayed in the second digit of the display 11. When the two characters of the 12-digit symbol are fully displayed on the display 11, including the first digit line head symbol 60, the display start address register 58 of the RAM 52 is displayed based on the action of the CPU 50. 1 is added to the number of digits, the characters displayed on display 11-to are shifted to the left, and the bullet 60 displayed in the first digit is changed to display 1.
Shifted out to outside 1. Also, print range setting key 4
6C Character data input beyond the preset right margin digits are stored in the line buffer section 54 and then in the auxiliary buffer section 55 for 10 digits.

When inserting new data into the data stored in the row buffer section 54 in this way, the printing range is set to 10 digits, for example, and the printing range is set to 10 digits. If you enter 10 digits of kana characters,
The end-of-line symbol 61 is displayed in the 12th column, and in this state,
If you want to insert the character data "<" or "ke" between "ki" and "ko", first move the cursor left movement key 35 to the J: Recurrful 40a to the 9th digit corresponding to the character "ko". move it to the position. In this state, when character data such as "<" or "ke" is input by operating the Kana character key 13, an inserted character is detected in step S1 as shown in FIG.
In step S2, the character data is transferred to the line buffer section 5.
4 is inserted at the specified location, and the "ko" after that
The data for "sa" and "shi" are shifted toward the lower digits. If there is data that overflows from the row buffer section 54 due to the shift 1, the data is transferred to the auxiliary barano section 55 and stored therein. Therefore, the data does not disappear and there is no need to re-enter it.

Thereafter, the process proceeds to step S3, where it is determined whether or not the position of the cursor 40a is at the right end of the cursor position register 59. Cursor 40a at position
If is displayed, the process advances to step S4. In this step S4, the display start address register 58
The number of digits plus "12" is the number of digits in row buffer 1 54
It is determined whether or not it matches the rightmost (right margin) digit of the printing range, and if they match, the process advances to step S5 and character data for 12 digits from the number of digits in the display start address register 58 is registered in the display buffer 56. Then, the characters "A~KO" are displayed on the display 11 as shown in FIG. 4(1)).

On the other hand, if it is determined in step S3 that the cursor position is not at the right end of the cursor position register 59, the process proceeds to step S6, where the cursor position register 59 is shifted to the right, and then the process proceeds to step S5. In addition, in the determination in step S4, if the number of digits of the display start address register 58 + 12 digits does not match the right margin digit, the process advances to step S7 and the number of digits of the display start address register 58 is set to "1". After that, the process moves to step S5.

Next, when deleting arbitrary data from among the data stored in the line buffer section 54, for example, as shown in FIG. When deleting the character data of "a" and "ij," first move the cursor 40a to the first digit position corresponding to the character "a" using the cursor movement keys 34 and 35. In this state, delete key 45 on keyboard 1o-t
When Jj is operated, the operation of the delete key 45 is detected in step S1 as shown in FIG.
The character data of "A" in the first row buffer 54 corresponding to the ON position of the cursor position register 59 is deleted.

Thereafter, the process proceeds to step S3, where it is determined whether or not there is data at the position next to the deleted location on the row buffer section 54. If there is data, the process proceeds to step S4. This step S4
In , the data after the deletion point in the row buffer 1 section 54 is moved by one digit in the direction of the upper digits, including the auxiliary buffer section 55, and then, in step S5, the data is moved by 12 digits from the number of digits in the display start address register 58. character data is registered in the display buffer 56 and displayed on the display 11. Further, in the determination in step S3, step S4
The process bypasses the process and directly proceeds to step S5.

After deleting the character data for "a", when the deletion key 45 is operated again to continue deleting the character data for "i", the operations of steps 81 to S5 are performed in the same manner as described above.
As a result, the data after the deletion location is moved from the original state by two digits corresponding to the number of digits of the deleted data, or to the upper digits, as shown in Figure 5 (1)). Characters will be displayed on the display 11. Therefore, there is no need to perform any special operations such as front-filling blank areas associated with data deletion.

Next, when printing the data input as described above, by operating the print key 36 on the keyboard 10,
As shown in FIG. 8, the operation of the print key 36 is detected in step S1, and in step S2, the character data in the line buffer section 54 is transferred to the print buffer 57, the line buffer section 54 is cleared, and the print buffer is Based on the data 157, one line is printed on the printing paper 6 by the C line printing device 8.

Thereafter, the process proceeds to step S3, where it is determined whether or not there is any data in the auxiliary buffer 1 section 55. If there is data, the process proceeds to step S4, where the character data in the auxiliary buffer 1 section 55 is transferred to the beginning of the line buffer section 54. The process then proceeds to step S5.

In this step S5, the cursor position register 59 is shifted from 1 to 1 so that the cursor 40a is displayed at the first N LJ L L position on the display 11 (at the position where no data is displayed), and the display start address register 58 is changed to the first position, and then step S6
Then, the character data in the buffer section 54 is transferred to the display pants r56 and displayed on the display 11.

On the other hand, if there is no data in the auxiliary buffer 1 section 55 in the determination in step S3, the process proceeds to step S7, and the cursor position register 59 is set vertically 1 so that the cursor 40a is displayed at the top position on the display 11. At the same time, the display start address register 58 is changed to the top position, and then the process moves to step S6. Therefore,
After the operation in step S6, the next line of data processing, etc. can be continued.

It should be noted that the present invention is not limited to the above-mentioned embodiments, and the configuration of each part can be arbitrarily changed without departing from the spirit of the present invention.

Effects of the Invention As detailed above, in this invention, when the data in the row buffer section in the input buffer is deleted, the data after the deletion point, including the auxiliary buffer section following the row buffer section, is The data is automatically moved in the direction by the number of digits of the deleted data, and there is no need for special operations such as front-filling the blank areas associated with data deletion, which has the excellent effect of improving operability. .
