Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a document creation/editing device such as a word processor capable of displaying scale lines on a display unit.

[Summary of the invention]

According to the present invention, when displaying a scale line on a display section, the scale line is displayed in a line near a line specified by a cursor or the like.

[Conventional technology]

FIG. 1 shows a display screen of a conventional word processor display device. On the display screen 1, a display pattern usually called a scale row 2 is displayed. The scale line 2 is provided with a mark 3 indicating the position of the right or left margin of the created document, and a scale 6 consisting of, for example, a large dot 4 every five characters and a small dot 5 every one character.

The scale line is used to represent the column position of characters in each line of the text 7 to be created on the screen, and serves as coordinate values when specifying an area.

[Problem that the invention seeks to solve]

However, in the above scale row, when you visually determine the column position of the characters in each line and calibrate or correct the characters in that column position, there is no particular problem at the top of the display screen, but when many lines of characters are When specifying a region, for example, character 8 indicated by "me" in FIG. 1 in the lower recorded row, it is often mistaken to be a character in the fifth column even though it is a character in the fourth column. That is, it is easy to misidentify the column position characters in the text in the lower row.
If an area is specified based on erroneous recognition in this way, the drawback will naturally be that the character arrangement will be incorrect.

The present invention has been made in view of the above-mentioned drawbacks, and its purpose is to provide a document creation/editing device that can recognize the column position in a document displayed below the screen display device without misrecognizing it. It is about providing.

[Means for solving problems]

The present invention provides a display means for displaying a created document on a screen, a line specifying means for specifying an arbitrary line on the screen using, for example, a cursor, and a line specifying means, for example, before or after the line specified by the line specifying means. A scale line (for example, a line in which large and small dots are arranged appropriately can be used) in the vicinity of the line.
and scale line display means for displaying.

[Effect]

Assuming that the document created by the display means is being displayed on the screen, when an arbitrary line on the screen is specified by the specifying means, the scale line display means displays a line in the vicinity of the specified arbitrary line. A scale line is displayed.

Therefore, even at the bottom of the screen, the column position of the scale row will not be misjudged.

〔Example〕

An embodiment of the present invention will be described in detail below with reference to the drawings.

(1) Configuration FIG. 2 is a diagram showing the front screen of a word processor to which the present invention is applied.

In FIG. 2, parts that are the same as those in FIG. 1 are given the same reference numerals, and redundant explanation will be omitted.

A guidance display line 9 is displayed at the bottom of the display screen 1 of the CRT.

In this embodiment, when the area to be edited or proofread is specified, the lines below line 7b, which is one line below the area specification line 7a to be edited or proofread, are scrolled down, and the area from the area specification line before being scrolled down is scrolled down. The scale row 10 is displayed at the position where the row 7b is located one row below. Further, in this embodiment, the pitch of the scale 11 displayed in the scale line 10 can be set arbitrarily, and the scale line is deleted when editing or proofreading is completed, and the text after editing or proofreading is Scroll up the next lower digit. Furthermore, the scale line is simply displayed without regard to the memory means (RAM) of the word processor.

FIG. 3 shows a block circuit diagram of a word processor to which the present invention is applied. In FIG. 3, 12 is a keyboard, 13 is a key discrimination section,
A command corresponding to each input key on the keyboard 12 is generated. In order to perform the control function of the display screen 1 mentioned above, an area specification command, an equal division command (a command for arbitrarily setting the pitch of the scale 11 mentioned above), an execution command, etc. are required, and the area specification command is output. Then, the control section 15 inquires of the cursor control section 14 about the current cursor address, and sets the register section 16. Also, when the equal division command is issued, the specified equal division value (scale line 10
The value determined by the scale pitch of
Set it to 6. Furthermore, when an execution command is output, the line below the current cursor line is scrolled down, the arithmetic unit 17 is driven to generate a scale line 10, and the display control unit 18 is controlled. The display section 19 corresponds to the display screen 1 shown in FIGS. 1 and 2.

As shown in FIG. 4, the register section 16 is composed of a first area address register 16a, a second area address register 16b, and an equally divided data address register 16c.

(2) Operation A flowchart showing the operation of the word processor having the above configuration is shown in FIG. 5, and will be explained below.

First, at the start 20, the first region a (calibration starting point) to be edited or proofread is indicated by moving the cursor, or the a coordinate is indicated by an appropriate method.

Next, the area specification key is determined 21. If the input key is an area specification key, the key determination unit 13
generates an area designation command and provides it to the control unit 15. The control unit 15 reads the cursor address 22 of the cursor control unit 14, and adds 1 to a key sequence counter for controlling the order in which keys on the keyboard 12 are pressed (23). Then, it is determined 24 whether the result is 1 or not.

If the key sequence counter is 1 (YES), the register section 1 shown in FIGS. 3 and 4
Set the first area address register 16a of 6.
26. On the other hand, by moving the cursor, the second area b to be edited or proofread (the final point of proofreading) is designated, and by pressing the area designation key on the keyboard 12, the cursor address is read 22 and the sequence counter 23 is set to +1. The addition is performed, and it is determined 24 whether the key sequence counter is 1 or not in the same way as described above. If it is not 1, set the second area address register 16b27
do. That is, the address of the first area is register 1.
6a, the address of the second area is stored in register 16b.
are set respectively.

If it is determined in the area designation key determination step 21 that the key is not an area designation key, a determination step 28 is made as to whether it is an equal division key 28 . If it is the equal division key, a message 29 is displayed on the guidance line 9 of the display screen 1 shown in FIG. If the equal division key 28 is not pressed but another key is pressed (N), the process naturally returns to the region designation key determination step 21.

The numerical value that the operator wants to divide the scale row 10 into equal parts based on the display of the guidance row 9 described above,
For example, if 2 is specified, the execution key is determined 30. If the input key is not an execution key, a determination 32 is made as to whether the input data is a numerical value.
If it is not a numerical value (N), it is an erroneous operation, so the execution key determination 30 is performed. In addition, each key identification 21,
28 and 30 are executed when each key is pressed.

As mentioned above, when a numeric key is pressed instead of the execution key, the key discrimination section 13 issues an equal division command to the control section 15 and sets the numerical data 2 in the equal division data address register 16c of the register section 16 33. . That is, when it is determined that the execution key 30 is not pressed, a determination 32 is made as to whether the numerical data of the equally divided data is between 0 and 9; If there is one, numerical data 2 is set 33 in the equally divided data address register 16c. When the execution key 30 on the keyboard 12 is pressed, the screen memory is scrolled down 31 from the line (scale line 10 position) one line below the line (area specification line) where the current proofing or editing is to be performed (area specification line). let Next, the calculation unit 17 is driven to start calculation 34. First area address register 16
For example, the current address of a is 6, and the current address of the second area address register 16b is 12, for example.
, and if the equal division data is specified as 2, the calculation result can be obtained from the following formula, 2nd area address register value - 1st area address register value / Equal division data = X = 12 - 6/2 = It becomes 3.

Next, equal division data creation 35 is performed based on the above calculation results. In creating the equally divided data Y,
A value of Y=first area address register value+above calculation result=6+3=9 is obtained. This value becomes equally divided data for one piece of equally divided data. Based on this value, scale line 10 is transferred to the line one line below the line to be edited or proofread in screen memory36
let In this manner, a scale line as shown in FIG. 2 is displayed 37 on the display screen of the display unit 16 based on the display control unit 18, and the process ends 38. In addition, in the above explanation, the equal division data is 2, so 6+3=9
However, when the number is 3 or more, Y=Y+X is sequentially repeated multiple times corresponding to the equally divided data. In other words, if the equally divided data is n, then Y = 1st area address + (n-1)
Find X. This Y becomes, for example, the display address of the "*" mark in FIG. 2, and the corresponding scale is displayed.

In this way, calibration or editing is performed using the scale 11 that is displayed on the scale row 10 and divided into equal parts, and after these editing and proofreading are completed, the scale row 10 and the scale 1 on the generated display screen 1 are displayed.
1 is deleted, and the lines immediately below the line specifying the area to be edited or proofread are scrolled up. To erase scale line 10, use keyboard 12
All you have to do is press the delete key inside and then press the equal division key. If the equal division, that is, the pitch has already been set, simply pressing the equal division key after moving the cursor will display the scale line and the equal division in FIG. 2.

The embodiment of the present invention shown in FIG. 3 is not limited to this configuration, and can be implemented using, for example, a microprocessor.

In each of the above-mentioned embodiments, the line to be edited or proofread, that is, the line one line below the area specification line, is scrolled down and the scale line 10 is inserted. Scroll up and add scale line 10
It is clear that you may insert .

〔Effect of the invention〕

Since the present invention is configured and operates as described above, it has the advantage of eliminating erroneous recognition of column positions in a document displayed at the bottom of the screen.
