Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing device such as a Japanese word processor, and more particularly to a line insertion function.

[0002]

2. Description of the Related Art Sanyo word processor Japan SWP-1
As disclosed in 100 Operation Manual, the conventional document editing apparatus has a one-line insertion function. That is, on the display screen, move the cursor to the left margin where you want to insert a line, and press the 1-character insertion key. A blank line is inserted in the line where the cursor is placed, and the contents after the line where the cursor is placed are Only one line is displayed.

Further, in the above word processor, in order to realize block editing, an indentation mark indicating a boundary can be displayed on the screen, and further, a ruled line can be freely drawn by using the cursor key to draw a desired line. You can create a table.

[0004]

In the conventional apparatus, when the one-line insertion function is executed in the table frame composed of continuous ruled lines, the insertion for which insertion is instructed is performed as in the case where the document is displayed. Since a blank line is inserted in the instruction line,
As shown in, the table was cut off, and the troublesome work of operating the cursor keys and connecting the ruled lines later had to be done.

[0005]

A document editing apparatus according to the present invention includes an input unit having an instruction unit for instructing line insertion, a text memory for storing a document input from the input unit, and contents of the text memory. And a display means for displaying, and in response to an instruction from the instruction means, display the contents after the insertion instruction line for which insertion is instructed forward, and
In a document editing device that displays a blank line in the insertion instruction line, in response to an instruction from the instruction means, it is determined whether the data of each column in the text memory corresponding to the insertion instruction line is ruled line data. Determination means, and if the determination means determines that it is ruled line data, it determines whether or not there is an upward directional component of the directional components of the upper, lower, left, and right directions of the ruled line data; When the presence of the direction component is determined, the vertical ruled line data consisting only of the vertical direction is written in the column position of the insertion instruction line,
Further, a row insertion unit is provided for making the column position of the insertion instruction line blank when the presence of the upward component is not determined by the determination unit.

Thus, according to the present invention, when a row insertion is instructed in the table, the contents after the insertion instructing row are displayed backward, and the insertion instructing row is searched, and if the ruled line data has an upward component. Displays vertical ruled lines consisting of only the vertical direction so as to be continuous in the column direction in the inserted line, and in other cases, a blank is displayed in the column position of the inserted line. That is,
When a row insertion is designated in the table, a blank row is inserted in the designated row while the table frame is continuous.

BEST MODE FOR CARRYING OUT THE INVENTION As shown in the block diagram of FIG. 2, the configuration of an embodiment of the present invention is a keyboard (1), a control unit (2),
The keyboard (1) is composed of a text memory (3), a video RAM (4) and a CRT display (5). The keyboard (1) has a one-line insertion instruction means composed of a cursor key (6) and a one-character insertion key (7). The storage control unit (15) includes the control unit (2), the text memory (3) and the video RAM.
Including (4).

The text memory (3) is a memory for storing a document input from the keyboard. Each data is composed of an attribute ATT and a character code CC as shown in FIG. Codes, ruled line codes, margin codes, etc. are stored. In the case of the ruled line code, as shown in FIG. 3B, ruled line direction component bits N, S, E, W indicating the respective components of the ruled line pattern are stored in the character code portion. The ruled line direction component bit NSEW is disclosed in detail in Japanese Patent Application No. 59-41169 filed earlier.

The specific operation will be described below with reference to the flowchart of FIG.

For example, as shown in FIG.
Is the first on the display screen (9) of the CRT display (5).
It is assumed that the cursor (10) is aligned with the left margin of the fourth line and the 1-character insertion key (7) is pressed in the state where the lines are displayed from the 7th line to the 7th line. Then, first, in the text memory (3), all the data after the insertion instruction line indicated by the cursor (10) are moved down by one line. At this point, the original data remains in the insert instruction line. Next, the data in each column of the insertion instruction line of the text memory (3) is read out, and it is searched whether this data is indent data or ruled line data. This is done by checking the attribute part of each data. When it is indented data, the data content of the column of the inserted row of the text memory (3) is retained.

If it is ruled line data, it is determined whether or not the upper component N of the ruled line direction component bit NSEW exists. If it exists, NSEW is placed in the same column of the insertion line of the text memory (3). The vertical ruled line data of "1100" is written. If the retrieved column data is character or symbol data and is not indent data or ruled line data having an upper component, a space code is written in that column, as in the conventional case.

Therefore, in the example of FIG. 4A, in the 1st, 5th and 9th columns of the 4th row where insertion of one row is instructed, the ruled line having NSEW having the upper component N is "1100". Since it is data, as shown in FIG. 4B, it is displayed on the 5th to 8th lines of the display screen (9) and on the 4th to 7th lines of FIG. 4A. The contents that have been displayed are displayed backward, and vertical ruled lines that connect the ruled lines of the previous line and the next line are displayed in the first, fifth, and ninth columns at the fourth line where insertion is instructed, and other A blank appears in the column.

That is, in the table (8), a blank line is inserted in the line instructed to be inserted while the table frames are continuous.

As shown in FIGS. 6A and 6B, in the case of indentation marks as well, one blank line is inserted while the indentation marks are continuous.

In the flowchart of FIG. 1, C is a variable indicating a column.

FIG. 5 shows another example of inserting one line in the ruled line display. In FIG. 1 (a), the direction component NSEW of the ruled line (11) of the second line which is the inserted line is " 1
010 ”, the vertical ruled line (12) is displayed, and as shown in FIG.
In (b), the ruled line (1
Since the direction component NSEW of 3) is “0110”, the space (14) is displayed.

[0017]

According to the present invention, when a row insertion is instructed in the table, the contents after the insertion instructing row are displayed backward, the insertion instructing row is searched, and the upward direction component exists in the ruled line data. In this case, vertical ruled lines that are continuous only in the vertical direction and are formed only in the vertical direction are displayed in the inserted row, and in other cases, a blank is displayed in the column position of the inserted row. That is, when a row insertion is instructed in the table, a blank row is inserted in the instructed row while the table frame is continuous, which eliminates the need for the conventional troublesome operation and is very convenient.
