Abstract

PROBLEM TO BE SOLVED: To use arbitrary kinds of ruled lines according to one's preference regardless of executing block editing by changing the state of block editing independently added to individual ruled lines in a document. SOLUTION: When a ruled line is inputted, a document editing processing part 2 prepares ruled line data of the ruled line in a ruled line data group 6 through a block editing state adding processing part 5. When the part 2 prepares ruled line data in the group 6, a part 5 sets this block editing state data to be turned on or off. In addition, the on/off of block editing state data in each ruled line data in the group 6 can be changed by a block editing state changing processing part 7. In this case, the on/off of block editing state data of ruled line data is judged to turn off this block editing state data when the judging result is turned on and to turn on this block editing state data when the judging result is off.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document creation / editing apparatus such as a Japanese word processor, and more particularly to a document creation / editing apparatus having a block editing function for editing a region delimited by ruled lines in a document independently of other regions. .

[0002]

2. Description of the Related Art Many document creation / editing apparatuses such as a Japanese word processor can input a ruled line in a document.
The ruled line is a linear diagram connecting two points in the document, and is mainly composed of a line direction (horizontal direction in horizontal writing, a vertical direction in vertical writing) and a column direction (perpendicular to the line direction). direction)
Are drawn in parallel with each other, but some can be drawn diagonally. In many cases, the line type can be arbitrarily selected from predetermined ones such as a thick solid line, a thin solid line, and a broken line. These ruled lines are used to create a table or the like by surrounding a specific area in the document or by further dividing this area. However, it is not limited to the case of making a table like this, and a single ruled line parallel to the row direction is arranged for each row and used to represent a line gap, or an area is defined by a single ruled line parallel to the column direction. It may be used to divide and form columns.

In a conventional document creation / editing apparatus, block editing is performed on an area delimited by the ruled line independently of other areas. In this block editing, for example, when characters are written horizontally in an area surrounded by ruled lines, if the characters sequentially arranged along the line direction are clogged up to just before the right vertical ruled line, digit breaks are automatically performed. Then, the character is arranged immediately after the left vertical ruled line on the next line, and the input character is edited so that the input character does not protrude from the left and right vertical ruled lines. The lower horizontal ruled line suppresses the subsequent input characters from protruding outside the lower area when the input characters are filled to the bottom line. Characters whose input is prohibited or protruding are automatically deleted, but lines may be scrolled within this area.
The four ruled lines also have a function of preventing characters input outside the area from entering the area. In addition, this block editing is not limited to the case where the area is completely surrounded by the ruled line. For example, even in an area which is sandwiched only by two vertical ruled lines and which is open above and below, while the cursor position is within this area, Digit breaks are performed, and the area from the beginning of the line to the vertical ruled line and the area from the vertical ruled line to the end of the line separated by only one vertical ruled line are also broken while the cursor position is within these regions. Do. That is, in this block editing, the vertical ruled line has a function of separating left and right input characters, and the horizontal ruled line has a function of separating upper and lower input characters.

[0004]

However, if all ruled lines are subject to block editing as in the above-described conventional document creation and editing apparatus, the block editing function can be performed even when ruled lines are used in portions where block editing is not intended. However, there is a problem that the input editing operation becomes troublesome.

For example, when ruled lines in the row direction are used to represent line spacing, these ruled lines separate each line.
Not only is it necessary to move the cursor beyond the ruled line to the next line each time you finish inputting for the line, but also because characters are not automatically advanced even if you make corrections in the upper line, Editing operations are cumbersome.

For example, as shown in FIG. 19, the money amount column 52 in the table created by the thick solid line ruled line 51 is replaced by the broken line ruled line 5.
When the amount is divided into three digits to make it easy to see the amount, the broken ruled line 53 is also subject to block editing.
2 is divided into five block editing areas 54 surrounded by wavy lines. Therefore, this money amount field 52 requires an operation of moving the cursor to the next block editing area 54 every time three digits are input to each block editing area 54,
The inconvenience that the amount cannot be continuously input occurs.

Therefore, in order to solve the above problem, a document creation / editing apparatus has been conventionally proposed in which only the ruled lines of some line types are subjected to block editing and the ruled lines of other line types are not targeted for block editing. (Japanese Patent Laid-Open No. 3-99360).

In such a document creation / editing apparatus, the input / editing operation can be facilitated, for example, by using ruled lines representing line spacings of a line type which is not subject to block editing. If the thick solid ruled line 51 is targeted for block editing and the broken line ruled line 53 is not targeted for block editing, the money amount field 52 shown in FIG.
As shown in FIG. 20, a single block editing area 54
Since the block editing area 54 is not divided by the dashed ruled line 53, four or more digits can be continuously input.

However, if it is determined uniformly whether or not a block is to be edited according to the line type of the ruled line, the ruled line of the line type to be block-edited cannot be used for a portion where block editing is not intended, and block editing is not possible. Cannot be used for a portion intended for block editing. Therefore, Japanese Unexamined Patent Publication No. Hei.
The document creation / editing device described in Japanese Patent Publication No. 0 presents a new problem that the line type of the ruled line cannot be freely selected.

For example, in the table of FIG. 19, a broken ruled line 53 is provided between the item column 55 and the confirmation column 56 and in these columns 55 and 56.
, The block editing area 54 in each of the columns 55 and 56 is separated, and the block editing area 54 in each of the sections 55 and 56 is also divided. However, JP-A-3-99
FIG. 20 created by the document creation and editing device described in Japanese Patent Publication No. 360
In this table, since the broken ruled line 53 is not a target of block editing, the item column 55 and the confirmation column 56 are collectively collected in a single block editing area 54. Therefore,
Unless the line type of the ruled line is changed, the respective columns 55 and 56
Since it is not possible to perform block editing for each rule or for each divided region, the freedom of selecting the line type of the ruled line is limited.

In addition, in order to perform block editing, all of the conventional document creation / editing apparatuses need to divide the area by ruled lines, and cannot use the block editing function in an area without ruled lines. There was also.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-described problems, and it is possible to set and change whether or not each ruled line in a document is to be subjected to block editing by changing the ruled line. It is an object of the present invention to obtain a document creation / editing device that can be used more freely.

[0013]

According to a first aspect of the present invention, there is provided a document creating / editing apparatus for displaying, on a screen, document creating data including characters and ruled lines, and inputting the document creating data. An input device for indicating a position on the display screen; and a document editing unit for editing a document while displaying document creation data input from the input device on a screen of the display device by a document display unit. ing.

The document creation / editing apparatus further includes a block editing state adding means for adding information indicating ON or OFF of the block editing state for each ruled line data representing each of the ruled lines input in the document; A block editing unit that performs editing independently of other areas in an area of the document separated by a ruled line whose block editing state is ON, and designates a ruled line in the document according to an input from the input device. A block editing state changing means for changing the block editing state of the ruled line to ON or OFF. Thereby, the above object is achieved.

According to a second aspect of the present invention, in the document creating / editing apparatus according to the first aspect, the block editing state adding means is provided when the input ruled line is parallel to the line direction of the document. Set the block editing state to be added to the ruled line data to OFF, and set the block editing state to be added to the ruled line data to ON if the input ruled line is orthogonal to the line direction of the document or has an inclination. It is configured to be set.

According to a third aspect of the present invention, in the document creating and editing apparatus according to the first or second aspect, a ruled line in the document is designated according to an input from the input device, and a line type of the ruled line is changed. In addition, there is provided a ruled line type changing unit for directly adding the block editing state added to the original ruled line data to new ruled line data.

According to a fourth aspect of the present invention, in the document creating and editing apparatus according to the first or third aspect, the block editing state adding means determines in advance for each line type according to the input line type of the ruled line. A document creation / editing device configured to set the block editing state to be added to the ruled line data to ON or OFF according to the given default value.

According to a fifth aspect of the present invention, in the document creating and editing apparatus according to any one of the first to fourth aspects, the block can be made visible on a screen display of the display device, invisible on a print output, and A provisional ruled line that is handled in the same manner as a ruled line whose block edit status is ON by the editing means is set to a block edit status of O within the same page in the document.
A temporary ruled line arranging means for arranging each ruled line which is N on the extension of the row or column of the document in the direction of increasing the number of lines and reaching another ruled line or temporary ruled line is provided.

According to a sixth aspect of the present invention, in the document creation / editing apparatus according to any one of the first to fifth aspects, the document display means displays each ruled line in a document on the display device on a screen. The ruled lines are displayed in different colors depending on whether the block editing state is ON or OFF.

Hereinafter, the operation of the present invention will be described.

In the present invention (claim 1), the block editing means performs the block editing only on the area divided by the ruled line whose block editing state is ON. In addition, this block editing state can be independently turned ON or OFF for each ruled line by the block editing state changing means. Accordingly, whether or not an area delimited by the ruled line is to be subjected to block editing can be individually determined regardless of the line type of the ruled line.

In the present invention (claim 2), when a ruled line is inputted into a document, if the ruled line is parallel to a line, the block editing state of the ruled line is automatically set to OFF, and the ruled line is set to OFF. If not, it is automatically set to ON. That is, a ruled line parallel to a line may indicate a space between lines. Therefore, a ruled line that is not automatically subjected to block editing at the time of input is set as a ruled line, and a ruled line not parallel to a line is used to block characters input along the line. Since it is often used as a delimiter of block editing, it is automatically set as a ruled line to be block-edited at the time of input. Therefore, just by inputting a ruled line, it is often the case that the ruled line is subject to block editing as intended by the operator. After inputting the ruled line, the block editing state is changed by the block editing state changing means. The need to do so rarely arises.

In the present invention (claim 3), when the line type of the ruled line is changed by the ruled line type changing means, the ON or OFF set in the block editing state of the original ruled line is inherited by the changed ruled line as it is. Become. For example, when a thick solid line is changed to a thin solid line or a broken line, the purpose is often to simply improve the appearance regardless of whether or not the ruled line is a target of block editing. Therefore, when the line type of the ruled line is changed, if the block editing state of the original ruled line is inherited in this way, there is almost no need to change the block editing state by the block editing state changing means thereafter.

Further, according to the above configuration (claim 4), when a ruled line is input into a document, the block editing state is automatically set to ON or OFF according to the line type of the ruled line. In general, a solid ruled line is intended for block editing, and a ruled line such as a broken line is often used for a portion not intended for block editing. Then, in most cases, there is no need to change the block editing state. Therefore, just by inputting a ruled line, it is often the case that the ruled line is subject to block editing as intended by the operator. After inputting the ruled line, the block editing state is changed by the block editing state changing means. The need to do so rarely arises.

In the present invention (claim 5), the provisional ruled line arranging means arranges the provisional ruled line on an extension of the same row or the same column of the existing ruled line. Block editing can be performed on the partitioned area by the block editing unit.

In the present invention (claim 6), it is determined whether the block editing state of each ruled line is ON or OFF.
The ruled line displayed on the screen can be identified by the color of the ruled line. In the present invention, since the block editing state is set independently for each ruled line, if ON and OFF states of the block editing state are mixed, the operator may not be able to grasp the area to be block-edited. However, if discrimination can be made based on the display color of the ruled line, there is no possibility of confusion.

[0027]

Embodiments of the present invention will be described below.

FIGS. 1 to 18 are views for explaining a document creation / editing apparatus according to an embodiment of the present invention. FIG.
Components having the same functions as those of the conventional example shown in FIGS. 9 and 20 are denoted by the same reference numerals.

In the present embodiment, a case will be described in which the document creation / editing apparatus is constituted by a computer. As shown in FIG. 2, this document creation / editing device is composed of a CPU 21 including a microprocessor and the like, and a storage device 22, a display device 23, a keyboard 24 and a coordinate input device 25 connected to the CPU 21 via a bus. Wear is configured. The storage device 22 includes a main storage device including a semiconductor memory and an auxiliary storage device such as a hard disk device. The display device 23 includes a CRT display, a liquid crystal display, and the like. The keyboard 24
This is an input device for inputting characters and the like, instructing an editing operation, and instructing other special operations. The coordinate input device 25 is used to specify position coordinates on the display screen of the display device 23. It is an input device such as a pen or a mouse for inputting a ruled line or indicating a cursor position or the like. In addition,
The keyboard 24 and the coordinate input device 25 can be replaced with other input devices if these inputs are possible. Further, the hardware configuration itself is not limited to such a configuration, and other devices can be added.

The above-mentioned document creation / editing apparatus executes a program in the main storage device of the storage device 22 by the CPU 21 to input characters, ruled lines, and the like from the keyboard 24 and the coordinate input device 25, and to input these to the display device 23. The document is edited while being displayed on the screen.

That is, as shown in FIG.
And characters and ruled lines input from the coordinate input device 25,
The data is sent to the document editing processing unit 2 via the input processing unit 1. The document editing processing unit 2 stores input characters and the like in the document data 3 according to the cursor position. Also,
When an editing operation such as character deletion, copying, or movement is instructed from the keyboard 24 via the input processing unit 1, the characters and arrangement in the document data 3 are corrected according to the contents. The document data 3 includes a sequence of character codes, and data for specifying the arrangement of the character codes, the font size, and the like are added as necessary, and a format and other data may be added. Then, the document data 3 is read out by the display processing unit 4 at any time and is displayed on the display device 23.
Is displayed on the screen.

When a ruled line is input, the document editing processing unit 2 creates ruled line data of the ruled line in the ruled line data group 6 via the block editing state adding processing unit 5. As shown in FIG. 3, each ruled line data includes ruled line color data 31, ruled line type data 32, coordinate data 33, and block editing state data 3.
4 The ruled line color data 31 is composed of a color code representing the color of the ruled line, and the ruled line type data 32 is composed of a code representing a line type such as a thick solid line, a thin solid line, or a broken line. The coordinate data 33 includes X coordinate data in the document indicating the starting point of the ruled line and Y coordinate.
It consists of coordinate data and X coordinate data and Y coordinate data in the document indicating the end point of the ruled line. These ruled line data of the ruled line data group 6 are read out to the display processing unit 4 as needed, and are displayed on the display device 23 as ruled lines on the screen according to the data 31 to 33. The block editing state data 34 includes a code indicating ON when the ruled line is a target for block editing, and a code indicating OFF when the ruled line is not a target for block editing. Then, when the document editing processing unit 2 creates ruled line data in the ruled line data group 6, the block editing state addition processing unit 5 sets the block editing state data 34 to ON or OFF. The block edit state addition processing section 5 may set the block edit state data 34 to ON or OFF uniformly, or may set the block edit state data 34 according to the inclination and line type of the ruled line, as described in detail later. .

The ruled line data group 6 includes the document data 3
The document creation / editing apparatus of this embodiment constitutes a document to be processed. The document is stored in a main storage device or an auxiliary storage device of the storage device 22 during the editing process, and is stored in the auxiliary storage device after the editing process is completed. And so on.

The ON / OFF of the block editing state data 34 in each ruled line data of the ruled line data group 6 is shown in FIG.
Can be changed by the block editing state change processing unit 7 shown in FIG. This block editing state change processing unit 7
Is a step (hereinafter referred to as “S”) as shown in FIG.
In step 1, it is monitored whether the block edit state change key is operated, and the block edit state change processing is executed only when the block edit state change key is operated. As shown in FIG. 5, a function key 27 on the keyboard 24 is assigned to the block edit state change key, and when the operator presses the function key 27, the input processing unit indicates that the block edit state change key has been operated. 1 is notified to the block editing state change processing unit 7. The block edit state change processing unit 7 may execute the block edit state change processing by another key operation, a plurality of key operations, or an operation such as menu selection instead of the block edit state change key.

When the block edit state change key is operated, a cursor for designating a ruled line is displayed on the display screen of the display device 23 (S2), and one of the ruled lines is designated by the cursor (S2). S3). To specify a ruled line, move the cursor to the target ruled line with the arrow keys of the keyboard 24 and press the execute key, or move the cursor to the target ruled line with the mouse of the coordinate input device 25 and click the mouse button. Can be performed. Also, as shown in FIG. 6, a target ruled line displayed on the screen of the display device 23 can be directly pointed to by the pen 26 of the coordinate input device 25, and can be designated by pressing a button or an execution key of the pen 26.

When the ruled line is designated in this way, first, the ruled line data of the ruled line is read from the ruled line data group 6 (S4). Next, it is determined whether the block edit state data 34 of the ruled line data is ON or OFF (S5). If the block edit state data 34 is ON, the block edit state data 34 is changed to OFF (S6). The block editing state data 34 is changed to ON (S7). That is, each time a ruled line is specified, the block editing state change processing unit 7 alternately switches ON / OFF of the block editing state. Then, by writing the changed ruled line data back to the ruled line data group 6, the processing of the ruled line is terminated (S8), and it is determined whether to process another ruled line (S9). Returning to S3, the block editing state change processing for the next ruled line is executed, and if not, the block editing state change processing ends. When the block editing state change processing is completed, the cursor for designating the ruled line displayed in S2 is deleted, and the screen returns to the original editing screen. Therefore, this block editing state change processing unit 7
Can change the block edit state data 34 to ON or OFF independently for each ruled line in the document.

The block editing state data 34 in each ruled line data is referred to when the document editing processing section 2 shown in FIG. 1 performs block editing. That is, as shown in FIG. 7, the document edit processing unit 2 monitors whether a block edit key is operated (S11), and performs block edit only when the block edit key is operated. As with the block edit state change key, another function key on the keyboard 24 may be assigned to the block edit key, or the block edit may be executed by another operation. Further, the document edit processing unit 2 may perform block edit as needed without providing a block edit key. When the block edit key is operated, the position of the cursor indicating the character input position is detected (S12), and ruled lines above, below, left and right of the cursor position are searched from the ruled line data group 6 (S13). This search is repeated in each of the upper, lower, left, and right directions until a ruled line in which the block editing state data 34 of the ruled line data is ON is found or the ruled line reaches the edge of the document (S1).
4) Recognize the area surrounded by the ruled line or the edge of the document thus found as the range of block editing at the current cursor position (S15). Therefore, the document editing processing unit 2 ignores the ruled line for which the block editing status data 34 is OFF, and sets the block editing status data 34 to O
Block editing is performed for an area divided by a ruled line of N.

With the above configuration (corresponding to claim 1), the document creation / editing apparatus of the present embodiment can arbitrarily set whether or not each ruled line is to be subjected to block editing by the document editing processing unit 2. As a result, the ruled line can be freely used as desired. For example, if the block editing state addition processing unit 5 uniformly sets the block editing state data 34 of all the ruled line data to ON, as it is, as shown in FIG. Block editing area 5
4 are also divided, but for only the broken ruled line 53 in the price column 52, the block editing state change processing unit 7 changes the block editing state data 34 of the ruled line data to O.
When the number is changed to FF, as shown in FIG. 8, the entire amount column 52 can be made into a single block editing area 54, and the amount can be continuously input by four or more digits. Moreover, the dashed ruled line 53 in the item column 55 and the confirmation column 56
Is the same line type as that of the money amount column 52, but the block editing state data 34 of the ruled line data remains ON. Therefore, unlike the case shown in FIG. The area 54 is separated, and the block editing area 54 is also divided in the respective columns 55 and 56, so that block editing can be performed for each block editing area 54. In FIG. 8, hatching is added to the right side of the broken ruled line 53 in which the block editing state data 34 is turned off to distinguish it from other broken ruled lines 53.

The case where the block editing state addition processing section 5 sets the block editing state data 34 to ON or OFF according to the inclination of the ruled line will be described. in this case,
As shown in FIG. 9, the block editing state addition processing unit 5
First, a ruled line in the same page is searched from the ruled line data group 6 (S21). When this ruled line is found, the starting point coordinates (X1, Y1) are obtained from the X coordinate data and the Y coordinate data indicating the starting point of the ruled line in the ruled line data. ) And (S2
2) The end point coordinates (X2, Y2) are obtained from the X coordinate data and the Y coordinate data indicating the end point of the ruled line (S23). next,
From these coordinates, the inclination of the ruled line (Y1-Y2) / (X1-X
2) is calculated (S24), and it is determined whether or not the inclination of the ruled line is 0 (S25). The inclination of the ruled line is calculated by the calculation processing unit 8 shown in FIG. If the inclination of the ruled line is not 0, the block editing state data 34 of the ruled line data in the ruled line data group 6 is set to ON (S2).
6) If the inclination of the ruled line is 0, the ruled line data group 6
OFF the block edit status data 34 of the ruled line data in
Is set (S27). When the setting of the block editing state data 34 is completed, the process returns to S21 and this process is repeated until the search for all ruled lines is completed.

Here, the rule that the inclination of the ruled line is not 0 means that the ruled line is orthogonal to the row direction or crosses obliquely with a slope as shown in FIG. The ruled lines that are not parallel to the line block the characters input along the line and are often targeted for block editing. The edit state data 34 is set to ON. Also, that the inclination of the ruled line is 0,
As shown in FIG. 11, the ruled line is parallel to the row direction, and such a ruled line is often not subject to block editing. Block edit status data 34 is turned off
Set to.

In FIG. 9, the block edit state addition processing section 5 executes the block edit state data 34 of the ruled line in the same page.
Are described collectively, but each time a ruled line is input, the processing of S22 to S27 may be executed to set the block editing state data 34.

With the above configuration (corresponding to claim 2), the block editing state addition processing section 5 automatically sets the block editing state data 34 to ON or OFF depending on whether or not the ruled line is parallel to the line. Even if the block editing state data 34 is not changed, in most cases, whether or not the ruled line is to be subjected to block editing is as intended by the operator, and the block editing state change processing unit 7
Operation time can be reduced.

The line type of the ruled line once input to the document can be changed by the ruled line type change processing unit 9 shown in FIG. The ruled line type change processing unit 9 also executes processing by operating function keys on the keyboard 24 in the same manner as the block editing state change processing unit 7 and the like. However, hereinafter, the process of monitoring the operation of the function key and the like will be omitted. As shown in FIG. 12, the ruled line type change processing unit 9 first specifies a ruled line by the same processing as in S3 (S3).
31) When this ruled line is designated, the ruled line data of the ruled line is read from the ruled line data group 6 (S32). Next, the line type to be changed is selected (S33), and the ruled line type data 32 of the ruled line data is changed to the selected line type (S3).
4). Then, the line type of the ruled line is changed by writing back the changed ruled line data to the ruled line data group 6 (S35).

With the above configuration (corresponding to claim 3), when changing the line type of the ruled line, the ruled line type change processing section 9 takes over the block editing state data 34 of the original ruled line as it is to the changed ruled line. become. Changing the line type of the ruled line in this way is often simply intended to improve the appearance, regardless of whether or not the ruled line is a target of block editing. Therefore, even when the block edit state data 34 of the original ruled line is changed by the block edit state change processing unit 7, when the line type of the ruled line is changed, the same change is again performed by the block edit state change processing unit 7. It is possible to reduce the trouble of performing.

The case where the block editing state addition processing section 5 sets the block editing state data 34 to ON or OFF according to the line type of the ruled line will be described. in this case,
The block editing state addition processing unit 5 refers to the ruled line type table 10 shown in FIG. That is, when a ruled line is input,
As shown in FIG. 13, the block editing state addition processing unit 5 reads a default value of the block editing state of the same line type as the input ruled line from the ruled line type table 10 (S4).
1). As shown in FIG. 14, the ruled line type table 10 sets a default value of a block editing state corresponding to each line type of the ruled line, and is stored in the storage device 22 in advance.
The default value of the block editing state is set to ON for a block that is frequently targeted for block editing, such as a thick solid line or a thin solid line, according to the line type of the ruled line, and is set to ON, such as a broken line or a wavy line. Items that are rarely targeted for block editing are set to OFF. The default value of the block editing state may be changed by an operation. When the default value of this block edit state is read,
The input block editing state data 34 of the ruled line is set to the default value (S42), the ruled line data of the ruled line is created in the ruled line data group 6 (S43), and the process is terminated.

With the above configuration (corresponding to claim 4), the block editing state addition processing section 5 automatically sets the block editing state data 34 to ON or OFF according to the line type of the ruled line. Even if the state data 34 is not changed, in most cases, whether or not the ruled line is to be subjected to block editing is as intended by the operator, so that the operation of the block editing state change processing unit 7 can be reduced. it can.

The document creating / editing apparatus according to the present embodiment performs block editing even in an area of the same page that is not separated by a ruled line when a ruled line with the block editing state data 34 ON is present in the document. can do.
That is, the provisional ruled line arrangement processing section 11 shown in FIG. 1 arranges provisional ruled lines on the extension of the existing ruled lines, and performs block editing even in an area delimited by the provisional ruled lines. The provisional ruled line arrangement processing unit 11 also executes processing by operating function keys on the keyboard 24 in the same manner as the block editing state change processing unit 7 and the like. However, hereinafter, the process of monitoring the operation of the function key and the like will be omitted. As shown in FIG. 15, the provisional ruled line arrangement processing unit 11 first reads the ruled line data of the first ruled line in the same page from the ruled line data group 6 (S51), and determines whether the block editing state data 34 is ON. Is determined (S52). If the block editing state data 34 is OFF, it is determined whether or not the next ruled line exists in the same page (S53). If there is, the process returns to S51 to return to the next ruled line. The same process is repeated for. in this case,
As for each piece of ruled line data in the ruled line data group 6, processing is performed from the one with the smaller value of X coordinate data or Y coordinate data indicating the start point of the ruled line.

In step S52, the block editing status data 34 is
If it is N, the ruled line is drawn in the direction of increasing X coordinates (row direction in horizontal writing, column direction in vertical writing) and Y
When extending in the direction of increasing coordinates (column direction in horizontal writing, row direction in vertical writing), it is determined whether each rule intersects another ruled line or provisional ruled line in the same page (S5).
4) If it intersects with a ruled line or a provisional ruled line, it is determined whether or not the ruled line intersects first (S55). If it intersects the ruled line first, a temporary ruled line is arranged between the original ruled line and the intersecting ruled line (S56), and if it intersects the temporary ruled line first, the temporary ruled line intersects from the original ruled line. A provisional ruled line is arranged before the ruled line (S57), and if it does not intersect with the ruled line or the provisional ruled line, a provisional ruled line is arranged from the original ruled line to the edge of the same page of the document (S58). When the provisional ruled lines are arranged in this way, the process shifts to S53, and when there are no unprocessed ruled lines in the same page, this process ends.

FIG. 16 shows an example in which temporary ruled lines are arranged in a horizontally written document by the temporary ruled line arrangement processing unit 11. Here, it is assumed that all the block editing state data 34 of the ruled line 41 indicated by the thick solid line is ON. Therefore, each ruled line 4
In 1, provisional ruled lines 42 indicated by wavy lines are respectively arranged on extensions of the X-coordinate increasing direction (right direction in the figure) and the Y-coordinate increasing direction (lower direction in the figure). FIG. 17 shows an example in which temporary ruled lines are arranged in a vertically written document. Here, it is also assumed that all the block editing state data 34 of the ruled line 41 indicated by the thick solid line is ON. Therefore, as for each ruled line 41, a temporary ruled line 42 indicated by a wavy line is arranged on the extension of the X coordinate increasing direction (left direction in the drawing) and the Y coordinate increasing direction (lower direction in the drawing).
When these provisional ruled lines 42 intersect with another ruled line 41 or the provisional ruled line 42 arranged earlier, the intersection position is set as an end point. It is extended to four side edges 43 indicating a range in which characters can be input.

Here, to arrange the temporary ruled line means to create ruled line data of the temporary ruled line in the ruled line data group 6. The ruled line data of this provisional ruled line is almost the same as the normal ruled line data, but the ruled line type data 32 is a special code representing the provisional ruled line, and the block editing state data 34 is always set to ON. The provisional ruled line having such ruled line data is displayed on the screen of the display device 23 by the display processing unit 4 and becomes visible, but is not printed out and becomes invisible. Further, the document edit processing unit 2 outputs the block edit state data 34
Is ON, it is targeted for block editing. Note that the provisional ruled line may be represented by completely separate data instead of ruled line data.

With the above configuration (corresponding to claim 5), the provisional ruled line arrangement processing unit 11 determines that the block editing state data 34
If there is a ruled line of N, another area in the same page is divided by a provisional ruled line, and block editing can be performed even in an area where no actual ruled line exists.

When the display processing unit 4 reads out each ruled line data from the ruled line data group 6 and displays it on the screen of the display device 23, the display color change processing unit shown in FIG. By using 12, it is possible to change the display color of the ruled line for which the block editing state data 34 is ON. As shown in FIG. 18, the display color change processing unit 12 first reads the ruled line data of the first ruled line from the ruled line data group 6 (S61), and determines whether or not the block editing state data 34 is ON. (S62). At this time, if the block edit state data 34 is ON, the display color of the ruled line is set to red (S63). If the block edit state data 34 is OFF, the display of the ruled line is performed. The color is set to black (S64). Then, it is determined whether or not the next ruled line exists (S6).
5) If it exists, return to S61 again and repeat the same process for the next ruled line.

If the next ruled line does not exist in S65, it is determined whether a temporary ruled line exists (S6).
6) The display color of all provisional ruled lines is set to red (S6).
7), the process ends. The display processing section 4 displays each ruled line with the display color set by the provisional ruled line arrangement processing section 11 on the display device 23.
On the screen. Note that the display colors of S63 and S67 and S6
The display colors of 4 are not limited to red and black as long as they are different colors.

With the above configuration (corresponding to claim 6), the ruled line and the provisional ruled line to be block-edited are displayed in a display color different from other ruled lines by the display color change processing unit 12, so that the operator can edit the block. It becomes possible to easily grasp the region to be performed.

[0055]

As described above, according to the document creating / editing apparatus of the present invention (claim 1), by changing the block editing state independently added to each ruled line in the document,
It is possible to arbitrarily determine whether or not an area delimited by this ruled line is to be subjected to block editing, and it is possible to use a ruled line of an arbitrary line type according to preference regardless of whether block editing is performed. become.

According to the present invention (claim 2), when a ruled line is input, ON or OFF of the block editing state is automatically set according to whether the ruled line is parallel to the line. Each time a ruled line is input, the trouble of setting the block editing state by operation can be reduced.

Further, according to the present invention (claim 3), when the line type of the ruled line is changed, the original block editing state is inherited as it is. Thus, the trouble of resetting the block editing state can be reduced.

Further, according to the present invention (claim 4), when a ruled line is input, ON or OFF of the block editing state is automatically set according to the line type of the ruled line. It is possible to reduce the trouble of setting the block editing state by the operation every time an input is performed.

Further, according to the present invention (claim 5), an invisible provisional ruled line can be arranged in an area without a ruled line in a document according to an existing ruled line, so that block editing is performed even in a region where no ruled line is input. Will be able to do it.

Further, according to the present invention (claim 6), the block editing state of each ruled line can be distinguished by the display color of the ruled line. Can be easily identified, and the boundary of the area to be block-edited can be determined at a glance.
