Abstract

PURPOSE:To easily know the positions in an input sentence and also to facilitate an easy editing job by displaying the line number to show the order of the line displayed by a display having a small number of display lines within the input sentence. CONSTITUTION:A memory unit 8 contains a line counting buffer 11 which checks the positions of lines in the data on the input sentences displayed on a display buffer 10. The buffer 11 performs a count-up action when a line shift is produced to the display on a display 2 in an input mode of the sentence data. While the buffer 11 performs the count-up/down actions when a line shift is produced with operations of the cursor up/down keys which indicate the line shift of the data displayed in an editing mode. The count contents of the buffer 11 are sent to the prescribed position of the buffer 10 when the display on the display 2 has a line shift with operations of the cursor up/down keys in the editing mode. Then the line numbers showing the count contents of the buffer 11 are displayed separately from other display data on the display 2.

Description

DETAILED DESCRIPTION OF THE INVENTION Technical Field The present invention relates to a word processor that has a display device with a small number of display lines and performs various text editing processes.

<Prior art> Word processors that perform various types of text editing processing include those equipped with a display device capable of displaying multiple lines, such as a CRT display, and those equipped with a display device capable of displaying a small number of lines, such as a liquid crystal display. There is.

The former type of display device is convenient because it allows you to see the entire text during the editing process, but
In addition, devices equipped with the latter display device are more convenient to handle because the entire device is smaller, but it is difficult to determine the line position of the displayed line in the entire text during editing processing. There is a problem that it is inconvenient in this editing process because it is difficult to know what is there.

Purpose of the present invention: In a small word processor having a display device with a small number of display lines as described above, the present invention is capable of displaying a line number indicating which line in a long sentence the line displayed on the display is. This makes the editing process convenient.

Furthermore, in the editing process, when the data to be displayed on one display line of the display device is moved, the line number of the display data is displayed at a predetermined position on the display.

<Embodiment> FIG. 1 is an external perspective view showing a word processor of the present invention, and FIG. 2 is a block diagram showing its control circuit.

In FIG. 1, the word processor includes a keyboard device l having a group of character input keys 1 and a group of control keys 2;
It is configured to be relatively compact by integrating a display 2 such as a liquid crystal display having one line of display digits and a printing device 3 such as a thermal transfer printer.

The control key group 2 includes a cursor up key 4a and a cursor down key 4b, which move the cursor up and down, that is, move the line of data displayed on the display line of the display 2; The cursor has left and right shift keys 5a and 5bt for shifting to the right, and also includes a selection key 6 for selecting various modes.

The control structure of such a word processor is as shown in FIG. That is, the word processor has a built-in editing control section 7 that performs editing control based on an editing control program, and is also equipped with an editing memory unit 8.

When a kana sentence is input from this keyboard device 1, the editing control section 7 introduces the corresponding character code into the display buffer 10 in the editing memory unit 8.
The contents are displayed on the display 2.

Subsequently, if there is an instruction for kana-kanji conversion, a kanji-mixed sentence corresponding to the kana sentence is read out from the kana-kanji conversion unit 12 and introduced into a predetermined position in the display buffer IO, and this kanji-majishi sentence is displayed on the display 201 line. displayed on the display line. The text data input line by line in this manner is sequentially stored in the text buffer 9 of the memory unit 8.

Further, when the text creation is completed after this editing process, the created text data is sent to the printing device 3 to be printed.

On the other hand, the memory unit 8 has a display buffer 10.
It has a line count buffer (counting means) (2) for checking the line position, that is, the line number, in the input text data for the data displayed on the screen. The count buffer 11 sequentially counts up when a line movement occurs in the display on the display 2 when text data is input, and also uses a cursor up key 4a and a cursor down key to instruct line movement of data to be displayed during editing processing. key 4b
etc. to move the line and upload it next time.

It's something that works down. The count contents of this count buffer II are calculated when the cursor up key 4a and cursor down key 4b are operated during editing processing and the display on the display 2 moves by line.Display buffer 1
0 to a predetermined position, and its count contents (row number) are displayed on the display 2 to distinguish it from other display data.

In other words, it is preferable for operation to input without paying much attention to the number of lines when inputting normal text, so the contents of the count buffer 110 are not particularly displayed during this input, and the display on display 2 moves lines during post-input editing processing. Then, when the cursor up key 4B + cursor down key 4b is operated, the count buffer 11
The line number of the currently displayed data, which is the count content of , is displayed.

The display of line numbers by this count buffer 11 is controlled according to the third factor, 74-Chard.

To explain the 70-chart in Fig. 3, the contents of the count buffer 11 are cleared when the device is powered on prior to text input or when the clear key is operated when inputting a new text. It is initialized to the '0' state (step S1).

After that, if the keys are manually operated and characters are input, step S
The process advances from 2 to 83, and character input processing is performed (step S4). If this character input is the first input character, the input for one line will not be exceeded, so the process goes through steps S5 and S6 and waits for the next key manually (returns to step S2).

When characters are input sequentially and do not exceed one line, the character input process is performed by repeating steps S2 to S6→S2.

Then, when one line of characters has been input, that is, when all the character data has been input into one display line of the display 2, this is detected in step S5, and the process proceeds to step S9, where the count buffer 1 is ■Increments the count up by ``I'', and then steps S6 again.
Return to step 2 and wait for the next key manpower.

Further, when the line feed key is operated, the process proceeds from step S2 to step S7, and a line feed process is executed (step S
s)o After that, proceed to step S9, count up the count buffer 11 by +1'', and then proceed to step S9.
It returns from 6 to 82 and waits for the next key manpower.

In this way, the count buffer 11 counts up each time a line moves beyond one line of input, and in other words, the number of input lines of display data input to the display buffer 10, which is the display line of the display 2, is counted up. In this case, the count contents of the count buffer 11 are not displayed in step S6.

Next, after inputting a text as described above, when performing text editing processing, when the key for instructing line movement of the data displayed on the display 2, that is, the cursor up key 4a or the cursor down key 4b, is operated. The process advances from step S2 to step S10, and line movement processing of the input text data is performed (step S).

After that, in step 512, it is judged whether or not the line has actually changed, and if the line has changed, step SI3
Then, it is first judged whether the cursor up key 4a was operated. If the cursor up key 4a is not operated, the contents of the count buffer 11 are counted up by l'' in step I4, and if the cursor up key 4a is operated, the process proceeds to step 15 and the contents of the count buffer 11 are increased by '1''. "Only the countdown will work.

After that, the process advances to step 16 and the count buffer 11 is
After displaying the contents of , that is, the line number, on the display 2, the process returns to step S2, waiting for key input.

Therefore, the line movement of the input text data and the line of the display data displayed on the display 2 in the entire text can be determined based on the contents of the count buffer 11 displayed on the display 2 (9 lines). You can tell by the number.

Display examples of the count contents of the count buffer 11 described above are shown in FIGS. 4 and 5, and FIG.
6 indicates text data stored in , and 6'' indicates line feed instruction data.

Further, FIG. 5 shows the relationship between the changes in the display contents on the display 2 and the line number display by operating the cursor up key 4a or the cursor down key 4b.

Initially, when the cursor points to the first line of the text buffer, the data of the first line is displayed on the display 2 as shown in FIG. 5(a).

For convenience, one line of display here is 6 digits, and K
is a cursor mark, and ``'' is a line feed indication mark.

When the cursor down key 4b is operated in the state shown in FIG. 5(a), the display on the display 2 changes as shown in FIG. This means that the data on the second line of the text buffer is displayed, and the content of the count buffer 11 becomes c'2'', and this line number is ``2''.
is displayed at the rightmost position of the display digit. The contents of this count buffer are displayed in a different display format to distinguish them from normal input data. In other words, the white and black colors are reversed from the normal display.

When the cursor down key 4b is operated in sequence, the contents displayed on the display 2 are switched to those shown in FIGS. 5(c), 5(d), 5(e), and 5(f). Further, even if the cursor down key 4b is operated in the state shown in FIG. 5(f), the cursor is positioned exactly at the last line of the sentence, so the line does not move and the cursor only moves to the end of the sentence on that line. In this case, since there is no line movement of display data, the contents of count buffer H are not displayed. (Step S1 in the flow of Figure 3)
2→S6) If the cursor up key 4a is further operated in the state shown in FIG. 5(c), the state shown in FIG. 6(h) is changed to the state shown in FIG.
), if a key other than the cursor up key 4a and cursor down key 4b is operated, for example, the cursor right shift key is operated, the cursor is shifted and the count buffer 11 is shifted as shown in FIG. 5(i). Contents are not displayed.

That is, the content of the count buffer 11, that is, the line number, is displayed only when the line of data displayed moves by the operation of the cursor up key 4a and cursor down key 4b, and when other keys are pressed manually, the line number is displayed. The contents of the count buffer 11 are not displayed for key processing.

Although the above embodiment does not display the line number when inputting characters, it is of course possible to display the contents of the count buffer 11 when inputting characters, if necessary. Further, although a display having one display line has been shown, the display can be similarly implemented with a display having about two or three lines.

Effects> The present invention is a word processor that has a display device with a small number of display lines and edits input text data while looking at the display surface of the display device, and when editing the text, one of the display devices When the data displayed on the display line of the line is moved, the line number that is the line position in the input text data of the data displayed on the display line is displayed on the display device to input the data. The position in the text can be easily found, which makes editing easier. Furthermore, by displaying the first line number in a format different from that of other display data, it can be distinguished from other display data, making it easier for the operator to confirm the line number.
