Abstract

PURPOSE: To conduct an inhibiting process which can avoid a vacant row is disposed at the head or tail row of a page. CONSTITUTION: A composing processor 30 functions as vacant row detecting means 34, and judges whether the head or tail row of a page is vacant or not. As a result of the decision, if it is vacant, the processor 30 functions as delimiter altering means 36. If the vacant row is disposed at the tail row of the page, in order to move the vacant row from the tail row, the number of the rows of the page is increased by one row to alter the delimiter of the page. If the vacant row is disposed at the head row, in order to move the vacant row from the head row, the number of the rows of the previous page is increased by two rows, and the delimiter of the page is altered.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a typesetting device for performing typesetting processing on document data.

[0002]

2. Description of the Related Art There are some prohibition processes in the typesetting process performed in a conventional typesetting device.
There was a process to avoid the chapter heading in the document from coming to the last line of the page.

[0003]

By the way, generally, in a document such as a novel, a blank line is used to mean "scene change". If the blank line comes to the first line or the last line of the page when typesetting such a document, the blank line becomes indistinguishable from the margin of the page, and the reader may overlook the blank line. There is. However, in the past, there was no prohibition process that avoids a blank line from coming to the first line or the last line of a page.

Therefore, an object of the present invention is to solve the above-mentioned problems of the prior art and to provide a typesetting processing apparatus capable of performing prohibition processing so as to prevent a blank line from coming to the first or last line of a page. Especially.

[0005]

In order to achieve the above-mentioned object, the invention according to claim 1 is a typesetting processing device for performing typesetting processing on document data, and a predetermined document of each page. In order to arrange the document data in a space with a predetermined character spacing and line feed, a delimiter that divides the document data in line units and page units, and the first line or the end of the page of the delimited document data. Detecting means for detecting whether or not there is a blank line, and at least the document data in a predetermined range located before the blank line when the detecting means detects the blank line. And a space change unit that increases or decreases the character space or line spacing to change the page space for the document data after the range. In the present invention, a blank line refers to a line in which all the lines in the line can be visually recognized as blank only when the document data is displayed or printed. Specifically, all the space character codes are used. Lines that consist of
The line that contains the line feed command as the first character is applicable.

As described above, according to the invention of claim 1,
According to the specified character spacing and line spacing, the document data is divided into line units and page units by the delimiter, and whether the delimited document data has a blank line at the first line or the last line of the page by the detection unit. To detect. If a blank line is detected, the delimiter changing means
Change the page breaks by increasing or decreasing the character spacing or line spacing for the document data located before the blank line. In this way, by changing the page break, the blank line that was in the first line or the last line of the page is moved from the first line or the last line.

According to a second aspect of the present invention, in the typesetting apparatus according to the first aspect, when the break changing unit decreases the change amount of the page break when the character spacing or line spacing is increased. And a means for calculating the change amount of the page break, and a means for changing the page break according to whichever of the increase or decrease in the character spacing or line feed is the calculated change amount. It is characterized by that.

As described above, according to the second aspect of the invention,
The change amount of the page break is calculated depending on whether the character spacing or line spacing is increased or decreased, and the page break is changed according to the increase or decrease of the smaller change amount.

According to a third aspect of the present invention, in the typesetting apparatus according to the first or second aspect, when the page break changing unit exceeds a predetermined allowable amount, the page break changing unit is configured to: It is characterized by including means for stopping the change of the page break and issuing a warning.

As described above, in the invention according to claim 3,
If the amount of page break change exceeds the allowable amount, stop page break change and issue a warning.

[0011]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing a typesetting processing apparatus as an embodiment of the present invention. As shown in FIG. 1, the typesetting device of the present exemplary embodiment includes an input unit 10 and a text storage unit 2.
0, the typesetting processing unit 30, and the typesetting processing text storage unit 4
0, a display unit 50, an output unit 60, and a control unit 70.

Of these, the input unit 10 is used to externally input designation of document data to be subjected to typesetting processing, an instruction to start typesetting processing, designation of various conditions for performing typesetting processing, and the like. The text storage unit 20 is a storage unit that stores a plurality of document data as a document file.

The typesetting processor 30 receives an instruction from the input unit 10 to start the typesetting process, and in accordance with various specified conditions.
This is a processing unit that performs typesetting processing on desired document data among the document data stored in the text storage unit 20.

The typesetting processing text storage section 40 is a storage section for temporarily storing the document data subjected to the typesetting processing by the typesetting processing section 30. The display unit 50 displays document data that has undergone typesetting processing.

The output unit 60 prints or stores the document data subjected to the typesetting process, and is composed of, for example, a printer or a hard disk. The control unit 70 transfers document data and other data and controls each unit. The typesetting processor 30 functions as a delimiter 32, a blank line detector 34, and a delimiter changer 36, as described later.

When the document data to be subjected to the typesetting process is designated through the input unit 10 and an instruction to start the typesetting process is given, the control unit 70 causes the plurality of documents stored in the text storage unit 20. The designated document data is read out from the data and sent to the typesetting processor 30. In the typesetting processing section 30, the input section 1
The typesetting process is performed according to various conditions designated through 0, the typesetting process command, and the like. After that, the control unit 70
The document data subjected to the typesetting process is stored in the typesetting process text storage unit 40 and displayed on the display unit 50. Further, the control unit 70 causes the output unit 60 to print or store the document data stored in the typesetting text storage unit 40 in accordance with an instruction from the input unit 10.

Of these, in the typesetting processor 30, first, a document space for pouring document data into each page is set in accordance with the paper size, the margin, and the orientation of each page designated via the input unit 10. Next, the typesetting processing unit 30 functions as a delimiter 32, and the document data is sequentially placed in the document space of each page based on the format information such as the character size, the character spacing, and the line feed specified via the input unit 10. The document data is divided into line units and page units for arrangement. When the division of the document data is completed in this way, the typesetting processing unit 30 then performs a prohibition process as described below for a blank line in the document data.

FIG. 2 is a flow chart showing an example of a prohibition processing procedure for blank lines performed by the typesetting processor 30 of FIG. As shown in FIG. 2, the typesetting processor 30 first sets S1.
In, the initial setting value “1” is set as the target page p and line g of the delimited document data. The target page p is incremented by "1" in S6 in order to sequentially target each page.

FIG. 3 is an explanatory diagram showing an example of document data before and after the prohibition process shown in FIG. 2 is performed. In FIG. 3, (a) shows the document data before the prohibition process, and (b) shows the document data after the prohibition process. In these figures, □, ◯, and ∘ respectively represent each character forming the document data, and the outer frames surrounding these characters represent the areas set as the document space in each page. Further, p indicates the target page as described above, g indicates the target line, and m indicates the line spacing on the target page p.
In the example of this document data, as shown in FIG.
The last line of the page (p = k) is a blank line. In the normal typesetting process, the space (line spacing) below the last line in each page is not included in the set document space, but in the present embodiment, for ease of explanation, , The space under the last line is included in the document space.

Now, assuming that the first row (g = 1) of the k-th page (p = k) is the target, in step S2 shown in FIG. 2, the target k-th page (p = 1). = K)
A line feed M ₀ designated via the input unit 10 is set as the line feed m in. In addition, since the number of lines G ₀ per page has already been determined by dividing the document data as described above, the number of lines G ₀ of the target k-th page (p = k) is set. Set as the last line g _E. In the example of the document data shown in FIG. 3A, the number of lines G
_{Since 0} = 5, the last row g _E is set to “5”.

Next, in S3, g is increased by "1",
The target line is moved down one line at a time, and in S4, it is determined whether the target line g is the last line g _E. As a result of the determination, if it is not the last row g _E , the process returns to S3 and repeats the same. If it is the last row g _E , S
Go to 5. Therefore, the fifth row (g) of the k-th page (p = k)
= 5) is the target, the fifth line is the last line g _E , and thus the process proceeds to S5.

In S5, the typesetting processor 30 functions as the blank line detecting means 34, and determines whether the target line g (in this case, the last line g _E ) is a blank line.
As a result of the determination, if it is a blank line, the process proceeds to S14, and if it is not a blank line, the process proceeds to S6. Since the fifth line of the k-th page is a blank line as shown in FIG. 3A, the process proceeds to S14.

In S14 and S15, the typesetting processing section 30 functions as the delimiter changing means 36, and in order to move the blank line which comes to the last line of the target kth page, from the last line, the kth page is moved. Change the page break by increasing the number of lines of. Specifically, in S14, the k-th
The line feed m in the page is reset from the value M ₀ set in S2 to the next value M ₁ .

M ₁ = M ₀ × g _E / (g _E +1) (Equation 1) However, the last row g _E is set to the value G ₀ (= 5) in S2.

By thus reducing the line feed m on the k-th page, the next k + 1-th page (p = k +
The first row in 1) is moved up to the kth page as shown in FIG. 3B, and the number of rows of the kth page is increased by one.

Since the number of lines is increased by one, the kth
Also in the last row g _{E of the} page, in S15, the value G ₀ (= 5) set in S2 is reset to the value G ₀ +1 (= 6).

In this way, by increasing the number of lines on the k-th page and changing the page delimiter, it is possible to move the blank line which has come to the end line of the k-th page to the line one line before the end line. .

The next k + 1th page (p = k + 1)
Then, since the first line is moved up to the kth page (p = k), the second and subsequent lines are moved up one by one, and the last line is moved to the next line as shown in FIG. 3B. The first row, which was on the k + 2nd page (p = k + 2) of, is carried forward. However, for page k + 1 and subsequent pages, line spacing m
Remains at the value M ₀ set in S2, and the number of rows does not change.

Next, in S13, the target row g
No. 6, which has been moved up to the kth page and has become the last line g _E
Go to the line (ie the line after the blank line) and again S
At 5, it is determined whether the sixth line is a blank line. Since the sixth line of the k-th page is not a blank line as shown in FIG. 3B, the process proceeds to S6, p is increased by “1”, and the target page is changed to the next k + 1-th page (p = k +
Move to 1).

[0030] In S7, the (k + 1) page is determined whether the last page P ₀ as a target, and the process ends if the last page P _0, the process proceeds to the last page P ₀ else S8, g Is set to "1" to set the target line as the first line. The final page P ₀ has already been determined when the document data is divided as described above.

In step S9, the typesetting processor 30 functions again as the blank line detecting means 34 to determine whether the target line g is a blank line. As a result of the determination, if it is a blank line, the process proceeds to S10, and if it is not a blank line, the process returns to S2. The k th
Since the first row (g = 1) of the +1 page is not a blank row as shown in FIG. 3B, the process returns to S2 and the same processing as described above is performed.

FIG. 4 is an explanatory diagram showing another example of the document data before and after the prohibition process shown in FIG. In FIG. 4, (a) shows the document data before the prohibition process, and (b) shows the document data after the prohibition process. In the example of this document data, as shown in FIG. 4A, the top row of the r + 1th page (p = r + 1) is a blank row.

Therefore, at the stage when S8 shown in FIG. 2 is finished, the first row (g = 1) of the r + 1-th page (p = r + 1).
Assuming that the eye is the target, in S9, as described above, the typesetting processor 30 functions as the blank line detecting means 34, and it is determined whether the target line g is a blank line. Since the first line of the s + 1th page is a blank line as shown in FIG. 4A, the process proceeds to S10.

In S10, S11, and S12, the typesetting processor 30 functions as the delimiter changing unit 36, and in order to move the blank line which is in the first line of the target r + 1 page from the first line, 1 The number of lines on the r-th page before the page is increased by 2 to change the page break. Specifically, after moving the target page p from the r + 1th page to the rth page in S10, in S11,
The line feed m on the r-th page is reset from the value M ₀ set in S2 to the next value M ₂ .

M ₂ = M ₀ × g _E / (g _E +2) (Equation 2) However, the last row g _E is set to the value G ₀ (= 5) in S2.

Thus, the line spacing m on the r-th page
, The r + 1th page (p = k + 1)
The first line (that is, the blank line) and the second line that were in FIG.
As shown in (b), the number of lines of the r-th page is increased by 2 to the r-th page.

Since the number of lines is increased by 2, the r-th
Also in the last line g _{E of the} page, in S12, the value G ₀ (= 5) set in S2 is reset to the value G ₀ +2 (= 7).

In this way, by increasing the number of lines of the r-th page which is one page before by two and changing the page break,
It is possible to move the blank line that has come to the first row of the (r + 1) th page to the line immediately before the last row of the rth page. In addition, as a matter of course, the number of lines on the r-th page, which is one page before, is increased by two lines instead of one line.
This is because the blank line comes to the end line of the r-th page.

On the r + 1th page (p = r + 1), the first and second rows are moved up to the rth page (p = r), so that as shown in FIG. The third and subsequent lines are rolled up by two lines, and the last two lines have the next r-th line.
The first row and the second row on the +2 page (p = r + 2) are carried up. However, for the r + 1th page and subsequent pages, the line feed m remains the value M ₀ set in S2, and the number of lines does not change.

Next, in S13, the target row g
To the rth page and the last line g _E
The line is moved to the line (that is, the line next to the blank line), and it is determined in S5 whether or not the seventh line is a blank line.
Since the 7th line of the r-th page is not a blank line as shown in FIG. 4B, the process proceeds to S6, p is increased by “1”, and the target page is changed to the next r + 1-th page (p = r + 1).

In step S7, it is determined whether the target r + 1th page is the last page P ₀ .
Since it is not the final page P ₀ as shown in, the process proceeds to S8, g is set to "1", and the target line is set to the first line. The subsequent processing is performed in the same manner as described above.

As described above, in the prohibition processing shown in FIG. 2, a blank line is positioned at the first line or the last line of the page by reducing the line feed m of the page and increasing the number of lines of the page. I avoided it, but on the contrary, page spacing m
Can be increased to reduce the number of lines on the page, thus avoiding blank lines at the first or last line of the page. Such prohibition processing will be described below with reference to FIG.

FIG. 5 is a flow chart showing another example of the prohibition processing procedure for blank lines performed by the typesetting processing section 30 of FIG. As shown in FIG. 5, the typesetting processing unit 30 first sets S
In step 21, the initial setting value “1” is set as the target page p and row g of the delimited document data. Note that the target page p is set to "1" in S26 in order to sequentially target each page.
It will be increased step by step.

FIG. 6 is an explanatory diagram showing an example of the document data before and after the prohibition process shown in FIG. 5 is performed. In FIG. 6, (a) shows the document data before the prohibition process, and (b) shows the document data after the prohibition process. In the example of the document data, the end line of the r-th page (p = r) is a blank line as shown in FIG. 6A, as in the case of FIG.

In FIG. 5, the processing of S22 to S24 is the same as the processing of S2 to S4 shown in FIG. Therefore, if the fifth line (g = 5) of the k-th page (p = k) is targeted now, FIG.
Since the fifth row is the last row g _E , as shown in, the process proceeds to S25 according to the determination in S24.

In S25, the typesetting processor 30 functions as the blank line detection means 34, and determines whether the target line g (in this case, the last line g _E ) is a blank line.
As a result of the determination, if it is a blank line, the process proceeds to S34, and if it is not a blank line, the process proceeds to S26. The fifth line on page k is shown in FIG. 6 (a).
Since the line is a blank line as shown in FIG.

In S34 and S35, the typesetting processing unit 30 functions as the delimiter changing unit 36, and in order to move the blank line coming to the end line of the target kth page from the end line, the kth page is moved. Change the page break by reducing the number of lines of 2 lines. Specifically, in S15, the k-th
The line feed m in the page is reset from the value M ₀ set in S2 to the next value M ₃ .

M ₃ = M ₀ × g _E / (g _E -2) (Equation 3) However, the last row g _E is set to the value G ₀ (= 5) in S22.

By increasing the line feed m on the k-th page in this manner, the fourth and fifth lines at the end of the k-th page are moved to the next k + 1th line as shown in FIG. 6B.
The number of rows of the k-th page is reduced by 2 when the number of pages (p = k + 1) is reached.

Since the number of lines is reduced by 2, the kth
Also in the last row g _{E of the} page, the value G ₀ (= 5) set in S22 is reset to the value G ₀ -2 (= 3) in S35.

In this way, the number of lines of the kth page is reduced by 2 and the page break is changed, so that the blank line which has come to the last line of the kth page is moved one line after the first line of the next k + 1th line. Can be made. Naturally, the number of lines of the k-th page is reduced by two lines instead of one, because a blank line comes to the top line of the next k + 1-th page only by reducing one line. is there.

The next k + 1th page (p = k + 1)
Then, as the 4th and 5th lines at the end of the k-th page (p = k) are moved down, the 3rd and subsequent lines are moved down by 2 lines as shown in FIG. 6B. , The 4th and 5th lines at the end are the next k + 2 page (p = k +
2). However, for the (k + 1) th and subsequent pages, the line feed m is the value M ₀ set in S22.
The number of lines remains unchanged.

Next, in S33, the target row g
Is moved to the third line (that is, the line two lines before the blank line), which is the last line g _E of the k-th page, and again S25.
At, it is determined whether the third line is a blank line. Since the third line of the k-th page is not a blank line as shown in FIG. 6B, the process proceeds to S26, p is increased by “1”, and the target page is changed to the next k + 1-th page (p = k +
Move to 1). In FIG. 5, the processing of S27 and S28 is similar to the processing of S7 and S8 shown in FIG.

FIG. 7 is an explanatory diagram showing another example of the document data before and after the prohibition process shown in FIG. In FIG. 7, (a) shows the document data before the prohibition process, and (b) shows the document data after the prohibition process. In the example of this document data, as in the case of FIG. 4, the first row of the r + 1th page (p = r + 1) is a blank row as shown in FIG. 7A.

Therefore, at the stage when S28 shown in FIG. 5 is finished, the first row (g = 1) of the r + 1-th page (p = r + 1).
Assuming that the eye is the target, in S29, as described above, the typesetting processing unit 30 functions as the blank line detection means 34, and it is determined whether the target line g is the blank line. Since the first line of the s + 1th page is a blank line as shown in FIG. 7A, the process proceeds to S30.

In S30, S31, and S32, the typesetting processor 30 functions as the delimiter changing unit 36, and in order to move the blank line which is in the first row of the target r + 1 page from the first row, 1 The number of lines on the r-th page before the page is reduced by one to change the page break. Specifically, after moving the target page p from the r + 1th page to the rth page in S30, in S31,
The line feed m on the r-th page is reset from the value M ₀ set in S2 to the next value M ₄ .

M ₄ = M ₀ × g _E / (g _E -1) (Equation 4) However, the last row g _E is set to the value G ₀ (= 5) in S22.

Thus, line spacing m on the r-th page
By increasing the last 5th
As shown in FIG. 6 (b), the row is the next r + 1 page (p
= R + 1), the number of rows of the r-th page is reduced by one.

Since the number of lines is reduced by one, the r-th
Also in the last row g _{E of the} page, the value G ₀ (= 5) set in S22 is reset to the value G ₀ -1 (= 4) in S32.

In this way, by reducing the number of lines of the r-th page by one and changing the page break, it is possible to move the blank line which has come to the first line of the (r + 1) th page to the one line after the first line.

The next r + 1th page (p = r + 1)
Then, since the first line at the end of the r-th page (p = r) is moved down, the second and subsequent lines are moved down one line at a time as shown in FIG. The line is further carried down to the next r + 2 page (p = r + 2). However, for the r + 1th page and subsequent pages, the line feed m remains the value M ₀ set in S2, and the number of lines does not change.

Next, in S33, the target row g
To the fourth line (that is, the line two lines before the blank line) which is the last line g _E of the r-th page, and S25 is again set.
At, it is determined whether the fourth line is a blank line. Since the fourth line of the r-th page is not a blank line as shown in FIG. 7B, the process proceeds to S26, p is increased by "1", and the target page is changed to the next r + 1-th page (p = r +
Move to 1). The subsequent processing is performed in the same manner as described above.

As described above, according to this embodiment,
When a blank line comes to the first or last line of the page, move the blank line from the first or last line by decreasing or increasing the page spacing m on the page and changing the number of lines on that page. , It is possible to avoid a blank line at the beginning or end.

In the embodiment described above, in the prohibition process shown in FIG. 2, the line feed m of the page is reduced to increase the number of lines of the page, and in the prohibition process shown in FIG. 5, the line feed m of the page is changed. I increased the number of lines on that page and changed the page breaks for each. However, for example, if there is a blank line in the first line or the last line of the page and there is a blank line every one or two lines from the blank line, the prohibition processing shown in FIG. There is a possibility that the number of lines will be increased or more, and that the prohibition processing shown in FIG. In that case, the appearance of the document on that page is significantly different from that of the other pages, which gives a feeling of strangeness to the reader of the document.

Therefore, when the number of lines that increase or decrease in this way becomes 3 or more, the process is temporarily stopped there, a warning is given to the operator, and it is determined whether or not the process is continued. You may ask the operator.

Further, the prohibition process shown in FIG. 2 and the prohibition process shown in FIG. 5 are integrated, and when there is a blank line in the first line or the last line of the page, the line feed m of the page is reduced. In this case, the number of lines to be increased and the number of lines to be reduced when the line feed m is increased may be calculated, and the prohibition process for the smaller number of lines may be performed. For example, FIG. 3 (a) or FIG.
As shown in (a), when the last line of the k-th page (p = k) is a blank line, in order to move the blank line from the last line, in the prohibition process shown in FIG. The minimum number of lines is increased by reducing the line spacing m of 1. However, in the prohibition process shown in FIG. 5, the line number of the page is reduced by 2 by reducing the line spacing m of the page. Looks bad. Therefore, in this case, the number of lines to be changed is smaller in the prohibition process shown in FIG. 2, and therefore the page break m is reduced to change the page break.

Further, in the above-mentioned embodiment, the page break is changed by increasing or decreasing the line feed m of the page. However, the present invention is not limited to this, and for example, in the page. The page breaks may be changed by increasing or decreasing the character spacing on some lines and increasing or decreasing the number of characters on that line. As a method of increasing or decreasing the character spacing, a method of increasing or decreasing the character size of a character, a method of increasing or decreasing the amount of space between characters, a method of increasing or decreasing both of them can be considered.

FIG. 8 is an explanatory diagram showing an example of changing the page break by reducing the character spacing of some lines in the page. In FIG. 8, (a) shows the document data before the change and (b) shows the document data after the change.

In the example shown in FIG. 8, for the first line and the second line, by reducing the amount of space between characters in the line,
Each increases the number of characters in the line. As a result, the characters on the third line are moved up to the second line and the third line disappears,
As a result, the blank line on the 4th line, which is the last line, becomes the 3rd line.
Move up to the line and move from the last line.

By the way, in the present invention, as described in claim 1, the range of increasing or decreasing the character spacing or the line spacing is at least a predetermined range located before the blank line. In the example
The predetermined range is within the page when the blank line is at the end line of the page, and within the previous page when it is at the top line of the page. However, the predetermined range may be at least any range as long as the blank line can be moved from the first line or the last line by increasing or decreasing the character spacing or line spacing within the range. Thus, for example, as the predetermined range to increase or decrease the line spacing m, the first row or page to the end row there is a blank line (hereinafter, referred to as page P _A) before the full page (or, most prior page P _A From each page existing up to the page having the headline in a close position), line feed m
The page is increased or decreased (hereinafter, referred to on page P _B) may be selected. As a method of selecting the page P _B , for example, when the line feed m is increased / decreased, the page having the smallest number of lines to be increased / decreased may be selected as the page P _B. However, in that case, if the increased or decreased line feed m, from the page P _B, blank on the first line or end line of each page up to the present page P _A from one page Previous (P _A -1) It must be conditional that the line does not come. When increasing or decreasing the character spacing described above, the page in which the number of increasing / decreasing characters in the line is the smallest per page may be selected as the page P _B.

Further, in the above-described embodiment, the page break for the document data is determined based on the number of lines. When the character string and the line feed command are combined as the document data, the number of lines can be managed depending on whether the number of characters exceeds the specified number of characters per line or whether the line feed command is included. If a page break command is added to the character string, the page break command may also be recognized as a page break. In this case, blank lines are provided up to the end of the page after the page break command, but there is no problem even if these blank lines still exist, so do not detect blank lines for these blank lines. To do.

In general documents, when blank lines are provided before and after headline sentences such as main subject and subtitle, there is no problem even if these blank lines come to the first line or the last line of the page. Therefore, the prohibition process may not be performed on those blank lines. Specifically, when a headline sentence exists in the document data, it is defined that the headline sentence is in that portion, and blank lines are not detected in the lines before and after that portion.

[0073]

As described above, according to the first aspect of the invention, when a blank line comes to the first line or the last line of a page, the character spacing or the line spacing is increased or decreased to separate the pages. Since it is changed, it is possible to move the blank line which was in the first line or the last line of the page from the first line or the last line to prevent the blank line from coming to the first line or the last line.

According to the second aspect of the present invention, the change amount of the page break is calculated depending on whether the character spacing or the line spacing is increased or decreased, and the change amount of the increase or decrease is small. Since the page break is changed by one person, the change in the appearance of the document on the page can be reduced by changing the page break.

According to the third aspect of the invention, when the change amount of the page break exceeds the allowable amount, the change of the page break is stopped and a warning is issued. Therefore, it is determined by the operator whether or not the subsequent process is continued. Can be judged.
