Each of these keys and behind the switch, code key 27
are the numeric keys 3 corresponding to the various printing functions of other keys, namely auto carriage return mode, light margin flash mode, centering mode, line-by-line mode, and underline mode.
When operated with any of the numbers 4 to 39,
This is for selecting each print function by generating code data different from the code data generated when those keys are operated alone.

Line-by-line mode means that the data input in advance is
This is a printing function that allows you to make corrections within the range of a line, and the right margin flash mode is a printing function that aligns the characters on each line to the right margin position. This is a printing function that prints characters in the center between the left and right margins. Furthermore, the O1 to underline modes are printing functions for printing various characters and simultaneously printing an underline.

In addition, the Iyl code key 27 is the number key 34~ mentioned above.
In addition to 39, when the inserter 1 to key 30, the pulley 1 key 31, the saw crane movement keys 32a, 32b, etc. are operated together, or when these keys are operated alone, the signal is emitted.

The first mode selection switch 28 is a two-position sliding switch for selecting one of two modes: typewriter mode and terminal mode, and this typewriter mode is used to use this typewriter as a normal typewriter. Terminal mode is a mode in which the typewriter is used as a data terminal device.

The second mode selection switch 29 is a 7j three-position sliding switch that selects one of three modes: non-print mode 1 to mode, collection print mode, and direct print mode. This is a mode in which characters manually entered using the keys are displayed on the LCD display 11 without printing by the head 5. Collection print 1 mode is a mode in which characters entered manually using the keys are displayed on the LCD display 11, and characters entered manually using the keys are displayed on the LCD display 11. The data that overflows from the display 11 or 5 is sequentially printed on the thermal paper 6 by the thermal head 5. Furthermore, in the direct print mode, characters input manually are displayed on the LCD display 11 and printed at the same time. This is a mode in which printing on the thermal paper 6 is avoided by marking the "-" mark 5.

Note that the other keys are provided in a normal typewriter, so their explanation will be omitted.

Further, the outer peripheral portion of the liquid crystal display 11 and each key 3

Therefore, when the designated line is changed by operating the keys 32a, 321+, and 27 of the line specifying means during this line inlet mode, the central processing unit 41 operates to change the line inlet mode from line inlet mode 1 to It is set to come out automatically.

Next, the operation of this typewriter will be explained with reference to FIG.

Now, when this typewriter is powered on by the power switch 7, the carriage 3 is moved to the left margin position (°j, display controller I) in step S1.
- Initialization of the roller 42, random access device 45, etc. is executed. Then, in step 82, if the key operation is "C key operation," then step S
In step 3, it is determined whether or not this is a line insert key operation using the code key 27 and inserter 1 to key 30.

If the determination result is YES, proceed to step s4,
If NO, the process jumps to step 87.

In step S4, it is determined whether the line insert mode has already been set, that is, whether or not the key operation using the code key 27 and the insert key 30 is the second operation to end the line insert; If the result is No, an in-read flag is set in the random access memory 45 in step S5.
The system enters the φ line insert mode in which data is inserted into the required line of the memory 49 for the lever 1, and returns to step S2 to wait for the next key operation. On the other hand, if the determination result in step S4 is YES, an error notification alarm is activated in step S6, and then the process returns to step S2.

If the result of step S3 is No, step S7
If the process proceeds to step S7, it is determined whether the key operation is an upward scrolling operation using the code key 27 and cursor movement key 328, and if the result is YES, the process proceeds to step S8. If NO, the process moves to step S14. In step S8, it is determined whether or not the state is in the crawling state -1~'U NEET. If the result is NO, the data in the text memory 49 is moved upward in step S. The moved line is the display controller] ~ roller 42
fr is output and displayed on the display 11, and then the process returns to step $2 and key operations are performed.

If the determination result in step S8 is YES, in step S10,
r 5TOP" is displayed, and in order to display the last line of the text inserted in step Sll, that line is moved in the text memory 49 (51jl J7jj). Then, in step 812, Jlj After the line after R of the inserted sentence is displayed on the display 11,
In step S13, the insert flag in the random access memory 715 is cleared, the line insert mode is exited, and the process returns to step S2.

-7'J, if the result of step S7 is No and the process advances to step S14, it is determined in step 814 whether the key operation is a downward scroll operation using the code key 27 and the cursor movement key 32b. If the result is NO, the process moves to step 815 and other processing is performed, and if the result is YES, the process moves to step 816.
Proceed to. In step 816, it is determined whether or not the line is in the inserted state, and the result is N.

In this case, the data in the text memory 49 is moved downward in step S17, and the moved line is displayed on the display 11, after which the process returns to step S2 and a key operation is performed.

If the determination result in step S16 is YES, in step 818 the display 11 displays lN5ERT5.
TOP" is displayed, and then, in step 819, the next line of the inserted text is displayed on the display 11. Also in the case of this step S19, the step S12
The process proceeds to step S13 in the same manner as in the above case, and after the insert flag of the random access memory 45 is cleared and the line is removed from the line entry 1-read, the process returns to step S2.

Does the typewriter of this embodiment operate as described above? Now, we will explain the operation in accordance with the order of operations when actually performing line inreading with this typewriter.

Now, for this Line Inser 1~, after turning on the power, press the code key 27 and cursor movement key 32a or 3211 to perform the 4-operation of 4-up or down scroll.
- + step S1 → S2 → S3 → S7 → S8 → S

4->S1'6->S17->S2, the process progresses 21, and it is possible to specify a desired line of the f-tater in the text meter 49 and display it on the display 1-1. Next, when the line insert keys are operated using the code key 27 and the in1 note key 30, steps S2→S3→S4→S5
→S2 and the processing progresses, the IN1 NO 1 flag is set in the random access memory 45, and the line inserter 1 is set.
~ Go into mode. After that, when an inserted sentence is entered by operating the alphabet keys 12, etc. on the keyboard 10, the process proceeds in steps S2 → S3 → S7 → S14 → 815, and the text is inserted into the specified line of the text I memory 49. inserted into.

After inputting the inserted text, in order to check the connection between the last line of the inserted text and the next line of the inserted text, press the upper screen [''-] button using the code key 27 or the cursor movement key 328 or 32b. Or, if you try to change the specified line by performing the down scroll key operation, steps S2 → S3 → S
7→S8→S10→S11→812→813→S2, or step S2→S3→S7→S14→S"16→S1
8→S'19→813→S2, the last line of the inserted text or the next line of the inserted text is displayed on the display 11, and the insert flag in the random access memory 45 is cleared to enter line insert mode. It will be handled automatically. Therefore, in order to end the line inserter 1 mode, it is not necessary to perform a special key operation for canceling the line inserter 1 mode, and the key operation can be simplified.

Effects of the Invention As detailed above, this invention eliminates the need for special key operations to finish the data insertion need in the data insertion mode for inserting data into a specified line of a text menu. , it is possible to automatically extract data from the data insertion mode by changing the specified line, thereby simplifying key operations.
