DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention divides a document which exceeds the display range of a display means into a plurality of parts, and divides these parts by the display means into a document such as a character line position and a digit position of each divided part. The present invention relates to a display control device for a plurality of display portions for simultaneously displaying the character positions of the characters.

[0002]

2. Description of the Related Art In a conventional display, a part of a document is displayed as it is. Therefore, a portion exceeding a display range of a display device may be in the same line of the document or in the same page. At the same time, it could not be displayed on the display screen.

[0003]

For this reason, there are Japanese-language input / editing apparatuses which display the widest possible range by reducing the size of the characters of the document to be displayed. However, this makes it difficult to read the characters. And the operator's eyes are tired. As another method, there is a Japanese input editing device that can set a plurality of fixed display portions on a CRT screen and display the plurality of portions, but the display portion is fixed.
Further, since a plurality of display portions are not associated with each other, the display portions cannot be changed so as to meet the editing purpose of the operator, and there is a disadvantage that it is troublesome to create a table or the like exceeding the display screen.

The present invention divides a document into a plurality of portions when displaying a document under input editing and proofreading in a Japanese input editing device or the like, and associates a line position or a digit position of the character being displayed with the document. It is an object of the present invention to provide a display control device which enhances the operability of inputting, editing and proofreading and checking work in document creation by a Japanese input editing device by displaying at least the plurality of portions simultaneously.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a character input means, a character editing and proofreading means, a display screen for displaying a character input and editing state, a screen scrolling means, and a storage means for storing a created document. Means for displaying a cross-shaped cursor on the display screen when division of the screen is instructed, thereby dividing the display screen into four display areas, and displaying the divided screen. Means for vertically or horizontally moving the cursor displayed on the screen to change the size of these display areas, and for horizontally scrolling the desired display area divided by the cross-shaped cursor. Interlocking display control means for interlocking and displaying the adjacent display area above or below this area in the horizontal direction so that the two digits are aligned, and the display area is divided by the cross-shaped cursor. When scrolling the desired display area in the vertical direction, the display area adjacent to the left or right of the area is interlocked in the vertical direction so that the two rows are aligned with each other. This is achieved by providing means for performing processing such as editing and proofreading in the divided display area.

[0006]

When a screen division is instructed, a cross-shaped cursor is immediately displayed on the display screen of the document, whereby the document display screen is divided into four and displayed. Therefore, when the document display screen is divided into four parts, the operation can be performed quickly. In addition, since the cross-shaped cursor is configured to be moved up, down, left and right by the cursor keys, the display screen can be easily divided at the table head and the rule portion, and the table creation can be speeded up.

In addition, since the cursor is set to a length corresponding to the vertical or horizontal width of the document display screen, when the document is divided and displayed, the divided portions and the left, right, up and down dividing directions are clarified, and the dividing operation is quick and accurate. It works to be able to do.

FIGS. 4 (a) to 4 (c) and FIGS. 5 (a) to 5 (b)
2 shows a data processing flow by the central processing unit 1 for displaying a plurality of portions of a document and a display screen on a display device.

The processing from the normal input / edit state 101 will be described. First, in the process 102, the above-described “screen division”
By inputting the signal of the key 601, the processing shifts to the processing 103, and a cross-shaped cursor 705 for dividing the display screen is displayed by the screen control program as shown in FIG. Here, the operator operates the cursor key 602 to move the cursor so that the input edit screen field has a desired division number and size. In this embodiment, in order to simplify the operation, if the cross point of the cross-shaped cursor is in the input edit screen field, it is divided into four parts. When the division and the cursor are completely out of the screen, the entire input / edit screen field is reduced in size as described below. In the process 104, the signal of the cursor key 602 is inputted, and when the movement of the cursor is completed, the "execute" key 605 is operated. By inputting the signal in the process 105, the next display magnification designation screen display process 106 become.

As shown in FIG. 4C, the display magnification designation screen is a display magnification display 70 for each of the divided screens.
6 and a virtual key 707 for designating the magnification by dividing the matrix display field into three rows. Here, the magnification of each display portion is designated. The standard size is determined as the initial value so that the designation is unnecessary if it is the standard size. In this embodiment, the reduction is 1/3, but this reduction ratio can be arbitrarily set to 1/2, 1/4, etc. in accordance with the display means. The cursor movement here improves operability by moving from one point in the divided screen to one point in the immediately adjacent screen. When a designation signal is inputted in the process 107 and the designation of the magnification is completed, the "execute" key 605 is operated. By inputting the signal in the process 108, the process proceeds to the association process of the next divided screen.

Next, the association of a plurality of display parts will be described. Here, associating is referred to as “interlocking” and not associating is referred to as “independent”. In this embodiment, the association is performed for the vertically and horizontally adjacent display portions.

In a process 109 of FIG. 5A, an interlocking designation screen is displayed as shown in FIG. 5B. In the present embodiment, a designated program is input by a virtual key 708. In this embodiment, a target program 709 is displayed in a half-turned black and white mode with emphasis displayed. And By looking at the display of these boundaries,
The boundary is filled with a pattern of light points if linked and a dark point if independent so that linkage and independence can be determined. By inputting an association signal in process 110 and inputting an "execute" key signal in process 111, the process proceeds to process 112, where a plurality of portions are simultaneously displayed as shown in FIG. 5 (c). , The input and editing status display. In the present embodiment, the association in the left and right display units is the row position, and the association in the upper and lower display unit is the digit position. Alternatively, it is also possible to add a process capable of associating digit positions on the left and right display units.

FIG. 6 shows a display control information table stored in the random access memory 2 for controlling display by associating a row position and a digit position on a screen divided into a plurality of portions. In the present embodiment, a case of four screens of screen numbers 1 to 4 will be exemplified. Reference numeral 201 denotes display unit size information, which represents the number of rows and the number of digits of each portion and the value of each of the portions by the number of dots, which can be displayed on a display device divided into a plurality of portions. Reference numeral 202 denotes a display magnification, which has a standard size of 1, and has a value such as 1/3 at the time of reduction. Reference numeral 203 denotes linkage information, which can be associated with up to two parts in this embodiment.
It has two pieces of data, and has information (A means a line position, B means a digit position is associated) associated with an associated screen number. Reference numeral 204 denotes current display position information, which has the head position of the currently displayed character in the number of pages, lines, and digits of the document. Reference numeral 205 denotes main screen information, which indicates where the display part where the cursor is currently located is on screen numbers 1 to 4. Recording is performed by setting the screen number at the cursor position to 1.

The contents of the display control information for screen number 1 in FIG. 6 will be described as an example. First, the size on the display device is 10 lines and 20 digits (vertical 28 dots in dot number).
(0 dots, 240 dots in width), display magnification is standard size, the associated display unit is line-aligned with screen number 2 (display part on the right side), and screen number 3 (lower display part)
Is a digit alignment, and the first character currently displayed is the first page, the first line, and the first digit of the document, and the cursor is present.

FIGS. 7 to 15 show a change in the display state of another display portion associated with a scroll instruction on the main screen portion or input of characters.

FIG. 7 shows an entire page of a document to be displayed as an illustrative example. As described above, it is impossible to check the whole page at a time on the display screen of the display device 7 for a page having a large paper size. Therefore, in order to simultaneously display distant portions of the document, the display screen is divided and each is displayed. For simplicity of description, only the input / edit screen field 701 in FIG. 3 will be illustrated and described.

A description will be given of a four-division example shown in FIG. The cross margin indicated by 710 is the boundary of division. For ease of explanation, the illustration is made such that the item number, the item name column, and the sales amount for one year can be displayed, except for the boundary display of the division. 711 is a first screen, 712 is a second screen, 713 is a third screen, and 714 is a fourth screen.

An example in which it is desired to confirm the sales of the product name cleaner of the document example shown in FIG. 7 on FIGS. 8 to 10 on the display screen will be described. First, move the cursor to the third screen 713,
If the "up scroll" key 603 is input here, the third
In the display area of the screen 713, display characters come up line by line as shown in FIG. Here, the "up scroll" key 60 is displayed until the name of the cleaner is displayed in the third screen.
If "3" is input, the column of the product name is sequentially raised and displayed as shown in FIG. At this time, the display of the fourth screen 714 is shown in FIG.
Is associated as shown in the display control information of
By scrolling up the third screen 713, the first screen 71
1 has no effect because the digit position is linked, but the fourth screen 71
4 is an interlocking of the row position, and is controlled by the display control program so that the fourth screen 714 becomes the same line as the display line of the third screen 713 is changed. Thus, when the name of the cleaner is displayed on the third screen, the sales amount of the cleaner is displayed on the same line of the fourth screen 714. That is, by scrolling up the item name column to the target cleaner, the column of the sales amount of the cleaner can be displayed on the fourth screen 714.

A display example in conjunction with the digit position will be described with reference to FIGS. For example, when it is desired to confirm the sales of 59 degrees of the product name cleaner on the display screen, the cursor is moved to the second screen 712, and the "left scroll" key 603 is input so that the display field of the year is 59. The display range of the second screen 712 is shifted by 16 digits (the scrolling digit can be set to 1 digit, 1 double-byte character (2 digits), or 8 double-byte characters (16 digits) at the time of high-speed scrolling). Then, as shown in FIG. 11, the display for 59 years appears in the display area.
At this time, as shown in the display control information in FIG. 6, the fourth screen 714 is linked by digit alignment, so that the sales column is sequentially scrolled to the left, and the fourth screen 714 is displayed in the year display field on the second screen 712. The surplus sales is displayed on the fourth screen 714. If the left display scroll is performed until the entire display column of the year 1959 appears on the display screen, the sales amount of the cleaner is also scrolled left while the digit position is matched, and the desired display can be performed as shown in FIG. You can also see the month of the cleaner number right away.

An example in which the screen display state is changed while characters are being input will be described with reference to FIGS. For ease of explanation, as shown in FIG. 13, it is assumed that the washing machine of item No. 30 has only the product name and the sales data has not been input. When data of the sales of the washing machine in the fiscal year 1983 is input until March 1983, the display screen is as shown in FIG. 14, and the next character input area is outside the display section. In this case, the Japanese input editing device of the present embodiment automatically performs left scroll so that the inputtable portion appears on the display portion. In this embodiment, block scrolling of 16 digits is performed, and the display screen is as shown in FIG. At this time, the fourth screen 7 automatically scrolled
The second screen 712 that is linked to 14 is also scrolled so that there is a digit position. Therefore, the data input for April of 1959 can be directly performed. The year column can be referred to as it is. Compared to the case of simply scrolling automatically, the divided display portion (the second screen 712 in this example) is linked, so that the input operation is extremely easy.

FIGS. 16 and 17 show the outline of the interlocking control part of the display control program for such display screen control. In these screens, the cursor and scroll directions are omitted unless otherwise required.

The display screen control as shown in FIGS. 8 to 10 will be described.

The central processing unit 1 receives a key input in a process 113 and determines the key content in processes 114 to 116. By inputting the “up scroll” key 603, the process proceeds from the processing 115 to the scroll subroutine 117.

As shown in FIG. 17, the scroll subroutine 117 first checks in step 1171 whether or not upward scrolling is possible. This is to determine whether there is room for upward scrolling in the display unit. For example, when the display unit displays the bottom line of the last page,
In processing 1172, abnormal sound generation processing is performed, and the processing ends. If it is possible, in step 1173, the corresponding screen is scrolled up, and the flow proceeds to step 1174 to refer to the display control information table shown in FIG. If there is a screen to be displayed, it is determined in step 1176 whether or not the control is for row alignment because the present example is scrolling upward. In step 1177, the screen is scrolled upward. In this example, item number 3 of screen number 3 in FIG.
The second “4” and “A” correspond, and the fourth screen 714 is controlled to scroll upward.

In the case of the display screen control shown in FIGS.
The same control is performed when the "left scroll" key 603 is input. The display control information table referred to at this time is “2” and “B” of 1 of item number 3 of screen number 4, and
This is the display control for digit alignment.

The control of the display screen at the time of character input shown in FIGS. 13 to 15 will be described. First, in the state of FIG. 13, the sales amount of the washing machine in 1983 is input. As the control of the program, after it is determined in step 116 that the character key is 610, the cursor position is determined in step 118 to determine whether scrolling is necessary. In this example, scrolling is not necessary until the sales amount for March in 1958 is input. Therefore, the input characters are displayed in step 121 through step 120, and the cursor is displayed in the next input position in step 122. When the input characters are input up to the state shown in FIG. 14, the next input character cannot be input or displayed without scrolling to the left, so that the process proceeds to the scroll subroutine 119 by the determination process 118 in FIG. As a result, the screen shown in FIG. 15 is displayed. At this time, also in the scroll control, the control of the digit position adjustment is performed as described above, and the scroll control is also performed in the year column synchronously.

[0032]

As described above, according to the present invention, when the screen division is instructed, the cross cursor is immediately displayed on the display screen of the document, and the document display screen is divided into four parts. In the case of dividing into four, it can be performed quickly.
In addition, since the cross-shaped cursor is configured to be moved up, down, left, and right by the cursor keys, the display screen can be easily divided by the table head and the rule part, and the table can be created quickly.

On the other hand, the cursor is set to a length corresponding to the vertical or horizontal width of the document display screen, so that when the document is divided and displayed, the divided portions and the left, right, up and down dividing directions are clear, and the dividing operation is quick and accurate. Will be able to do it.
