A shift flag save register 60 is provided in which the contents of the shift flag save register 60 can be temporarily saved.

Then, the CP jJ 50 sequentially stores data corresponding to kana characters etc. input from the keyboard 1o in the line buffer 56 of the RAM 53, reads out pattern data corresponding to the data from the ROM 52, and sends it to the display 11 and printing device 8. supply

The RAM 53 includes a cursor position register 63 for storing the cursor position on the display 111.
A cursor font register 64 for storing cursor dot patterns and a font buffer 65 for storing dot patterns corresponding to various character 10-codes are provided. Then, in accordance with the operation of various keys, the CPU 50 reads a character code from the line buffer 156, accesses the font data corresponding to the character code from the character generator 571,
The font data is stored in the 7-onto buffer 65. Further, the CPU 50 reads cursor font data from the cursor font register 64 in accordance with the cursor position stored in the cursor position register 63, and reads the cursor font data from the cursor font register 64.
Ontobuff 765 combines character font data and cursor font data and transfers the resulting signal to display 11.

Next, processing related to the present invention will be explained with reference to FIGS. 5 to 7. Now, when the power is turned on by the power switch 7, the guidance 40b is displayed pointing to "Hiragana" among the mode display characters 41, as shown in FIG. 2, and the kana input mode is automatically set. Next, when the printing range setting key 46 is operated, step S1 shown in FIG.
In step S2, the print range setting signal is detected, and then in step S2, the kana input mode flag and shift flag are saved in the save register 58 and shift 1 to flag save registers 60, respectively. And step S3
, the input mode is automatically changed to a printing range setting mode in which a numeric code can be entered, and a guidance 40b is displayed pointing to one alphanumeric character among the mode display characters 41 shown in FIG. 7(a). . At the same time, the contents of the shift register 59 are cleared.

Next, in step S4, the previously set printing range is displayed on the display 11 as shown in FIG.

At this time, a print range setting screen is displayed on the display 11, and the 5th, 6th, 9th, and 0th digits are available positions.

Next, when a numeric key such as "1" is operated to change the printing range, it is detected in step S5 whether or not the numeric key has been operated, and in this case, the result is YES, so the process proceeds to step S6 and the numeric data is is stored in input buffer 1. At the same time, the number "1" is displayed in the fifth digit, as shown in FIG. 7(b). Next, the process advances to step S7, where cursor movement processing is performed. Then, as shown in FIG. 6, in step 820, it is determined whether or not the cursor position before performing the cursor movement process was the fifth digit of the display 11. If the result is YES, the process advances to step S21 and the cursor position is 40a is moved to the right to the 6th digit as shown in FIG. 7(b), and is stored in the cursor position register 63. Next, the process advances to step 827 , where the font buffer 6 corresponds to the contents of the cursor position data of the cursor position register 63
After the cursor position is registered in 5, the line buffer 156 is first
The font data and cursor font data corresponding to the 6th digit numerical data "1" stored in the 6th digit are combined and transferred to the display 11, and the 9th digit is displayed corresponding to the numeric data and cursor data. It will be done. In other words, NJ is displayed in this real 13-Zettai. Next, when a numeric key such as "0" is operated to change the number in the sixth digit, the numeric key detection operation is performed again in step S5, and since the result is YES, the process advances to step S6, where the numeric data is is stored in the row buffer 56, and at the same time,
It is displayed on the sixth digit of the display 11 as shown in FIG. 7(C). Thereafter, the process advances to step S7 and cursor movement processing is performed. Then, as shown in FIG. 6, since the determination result in step 821 is No, the process proceeds to step S22, where it is determined whether the cursor position is at the 6th digit, and if the result is YES, the process proceeds to step 823. The cursor 40a is moved to the right to the 9th digit. Next, the operation of step 827 is performed in the same manner as in the previous case.

After that, when a numeric key is operated to change the number in the 9th digit, the process returns to step S5, a numeric key operation detection operation is performed, and the numeric key that was operated in step S6, for example, the number corresponding to "2". The data is stored in the row buffer 56 and displayed in column 9 of the 14-display 11. Subsequently, cursor movement processing is performed in step S7, and the determination results in steps 820 and 822 are both N'0, and the process proceeds to step 824. In this step 824, it is determined whether the cursor position is at the 9th digit or not. In this case, since the result is YFS, the process proceeds to step S25, and the cursor 40a is moved to the right to the 0th digit on the display 11.

After the operation of step 827 is subsequently performed, if one of the numeric keys, for example, the key "5" is operated to change the display of the 0th digit, the process returns to step S5 and a numeric key detection operation is performed, and then the process returns to step S6. The numerical data corresponding to "15" is stored in the line buffer 56 and displayed on the 0th digit of the display 11, and then in step S7
The process advances to step 31, where processing for moving the cursor 40a is performed. In this case, since the cursor 40a was at the 0th digit, step S2
The determination results of 0.822 and 824 are both N.

The process then proceeds to step 826, where the cursor 40a is returned to the fifth digit. Then, the operation of step 827 is performed.

In this way, the setting of the printing range is changed, and the left and right margin positions are set to 110 as shown in FIG. 7(e).
Digit - 25 digit" is displayed. When the printing range setting key 46 is operated again after that, it is determined in step S10 whether or not the printing range setting key 46 has been operated.
If the result is YES, the process advances to step S11, where the previously set kana input mode flag and shift I~ flag are restored, and at step 812, the printing range is registered and the printing range setting mode is canceled. , the print range display is cleared.

As is clear from the above operation, the print range setting key 46
By pressing down, the input mode will automatically switch to the print range setting mode where you can input numerical codes.
There is no need to set the alphanumeric manual mode by pressing the alphanumeric mode key 38, and since the cursor 40a only moves between the digit positions for displaying numbers when setting the print range, the print range setting operation can be performed easily. It's easy to do. Furthermore, in this embodiment, if a key other than the print range setting key 46 is operated after setting the print range, the determination result in step S10 becomes No, and the process proceeds to step S14, where the buzzer emits a warning sound. The operation can be performed reliably. Furthermore, a warning sound is also emitted when the number of digits indicating the right margin position is greater than 40.

On the other hand, when changing the numerical value in a required digit on the display 11 after operating the print range setting key 46,
As shown in FIG. 7(a), when the cursor right movement key 34 is operated with the printing range displayed, step S8
The determination result in is YES, and the process proceeds to step S7.
Then, the cursor right movement process described above is performed. Therefore, move the cursor 40a to the right to the required digit, and press the numeric key 12°1 at the digit position indicated by the cursor 40a.
You can change the numerical value by operating 6.

Also, when the cursor left movement key 35 is operated, step S
The determination result in step S9 becomes YES, and the process advances to step S17--Tub S8, where substantially the same cursor movement processing to the left as in step S7 is performed. Therefore, the cursor 40a can be moved to the left to the required digit.

Effects of the Invention As detailed above, this invention controls the movement of the cursor only to positions that can be set as print range data on the print range setting screen, so the print range setting operation can be quickly performed with fewer key operations. It has excellent effects.
