Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a document editing apparatus, and more particularly to editing a document or a graphic such as a word processor, desktop publishing system, general-purpose two-dimensional drawing system or schematic editor. And a document editing apparatus suitable for use as an apparatus for displaying a document or a figure such as a hypertext display system, a drawing data display apparatus or an image display apparatus.

2. Description of the Related Art Conventionally, in a word processor or desktop publishing system, when a document composed of a plurality of pages is edited or when the document is displayed, the document is displayed. When displaying on the screen of the device, a method of displaying only one page in the document or a method of displaying at most about two pages has been adopted.

Generally, the reason why such a display method has been used is that the resolution of the display device and the human visual acuity are limited, and the display device is adapted to such a limit.

As a means for displaying the positional relationship of the page currently displayed on the screen of the display device in the entire document, for example, the total number of pages and the screen are displayed. There was a method to display a character that indicates the number of pages and the number of pages.

However, such a character display has a problem that it is difficult to visually and intuitively grasp the entire positional relationship.

There has also been a method in which one page is represented by one icon and such icons are arranged in page order and displayed.

This method is easier to visually understand the positional relationship of the pages than the method of displaying the characters indicating the total number of pages and the number of pages displayed on the screen as described above. Good, but if you want to edit or view a document with many pages,
There is a problem that it is not possible to display all the icons representing a page on the screen at once.

In the presentation slide creating system, there is a function of displaying a list by reducing the size of pages, but this also displays a document consisting of many pages such as books and papers similarly to the method described above. However, there is a problem in that all pages of the document cannot be displayed on the screen of the display device at one time.

The problems similar to those described above are not limited to word processors and desktop publishing systems, but also to editing systems and display systems in various fields described in the above-mentioned "Technical field to which the invention belongs". It is applicable.

As a method of indirectly informing the user of the position currently being edited in the document,
Documents are represented as data with a hierarchical tree structure such as "chapter", "section", "paragraph", etc., and the method of specifying the hierarchy such as "chapter", "section", "paragraph" etc. is there.

However, in the method of expressing a document as data having a hierarchical structure as described above, the user must compose the document by a method with a very low degree of freedom, which is a hierarchical structure in a tree structure. Not only is it forced, but there is a problem that the implementation becomes complicated for the developer who creates the editing system.

In other words, in the method of expressing a document as data having a hierarchical structure such as a tree structure, the user himself / herself considers the input, regardless of the case of inputting a manuscript prepared in advance. When creating a document, the following two important requirements are required: (1) You can freely start where you want to write (2) The user should fix the structure of the entire document in advance. It was extremely unsuitable because it could not satisfy the requirement to create documents flexibly.

The present invention has been made in view of the above-mentioned various problems of the prior art, and an object of the present invention is to allow a user to visually recognize the amount of documents and the positional relationship in the documents. An object of the present invention is to provide a document editing device that enables intuitive grasping, and also makes it possible to grasp the structure of the entire document easily and easily create a document with a free structure. To do.

[0014]

In order to achieve the above object, a document editing apparatus according to the present invention is a document editing apparatus for editing a document page by page, and a document storage means for storing a document composed of a plurality of pages. And a document display means for displaying the document stored in the document storage means, and a page stack which is a row of one or more pages obtained by dividing the document stored in the document storage means in page units. Page stack storage means, page stack display means for displaying the page stack stored in the page stack storage means, page selection means for selecting a page of the document displayed by the document display means, and the page stack storage It is obtained so as to have a page stack editing means for changing the configuration of the page stack which is stored in the stage.

A page stack dividing unit that divides the page stack into two page stacks, and a page stack that moves one or more page stacks of the page stacks stored in the page stack storage unit immediately before or after another page stack. It may have a moving means.

Further, the page stack display means may display each page stack in a size corresponding to the amount of pages of the document forming each page stack stored in the page stack storage means.

Further, the page stack storage means is
The page numbers of the pages of the document corresponding to the pages that make up each page stack are stored, and the page stack is stored so that the first page of the page stack is arranged in ascending order of the page numbers of the pages in the corresponding document. , The pages in the page stack are stored so as to be arranged in ascending order of the page numbers of the pages in the corresponding document in the page stack, and the page stack editing means stores the page stack in the document corresponding to the first page of the page stack. Pages within a page stack may be kept in ascending order of page numbers, and pages within a page stack may be kept in ascending order of page number within the corresponding document in the page stack.

Furthermore, the page stacks stored in the page stack storage means are real pages showing the substance of the pages of the documents forming each page stack,
Reference page creating means for creating reference pages in the page stack from actual pages, and reference page deleting means for deleting the reference pages from the page stack. May be included.

Further, the page stack display means displays the pages of the document forming each page stack by a rectangular figure, and when displaying the page stack composed of a plurality of pages, a rectangle for displaying each page. May be displayed after being displaced by a predetermined amount.

Further, at this time, the page stack display means may display the page number in the rectangle, or may display the document of the page corresponding to the rectangle in the rectangle in a reduced size. May be.

Further, the page stack display means may display the rectangle corresponding to the page selected by the page selection means in a mode different from that of the rectangle corresponding to the unselected page.

Therefore, according to the document editing apparatus of the present invention, by referring to the page stack, the user can visually and intuitively grasp the volume of the document and the positional relationship within the document. It is possible to easily grasp the entire structure of the document, and it is possible to easily create a document having a free structure.

In other words, when the user edits or displays the document, the user can graphically display the amount of the document and the position of the page currently displayed by the page stack so that the user can display the amount of the entire document. Since the structure and the current page position can be easily grasped visually and intuitively, the memory load on the user can be significantly reduced.

In addition, when editing / creating work in parallel at a plurality of positions in a document, such as when editing an existing document or newly creating a document having many pages, By referring to the page stack, it becomes easy to change the position of the current page, and the work efficiency is improved.

Furthermore, the number of pages of the entire document is
Since the size of the page stack is displayed as a visual expression, it becomes possible to intuitively grasp the progress of the document creation work, and the burden of the user on the work time and work schedule is reduced.

Furthermore, since the page stack can be freely edited, the degree of freedom when a user creates a document is improved, and a document having an arbitrary structure can be easily created. Since the whole can be grasped quantitatively, the user can efficiently perform the document creation work.

The "page" and the "page in document" included in the page stack have a one-to-one correspondence.

Further, as the data structure of the page in the document, any structure can be adopted.

Next, the contents of processing executed by the above-mentioned document editing apparatus will be described with reference to the flow chart, but in the following, only the details of the page stack display processing in the area 30c which is the subject of the present invention will be described. An explanation shall be given.

Among the processing contents executed by the document editing apparatus described above, the document editing apparatus 1
Since the document editing process executed by the method 6 is a conventionally known technique, the description thereof will be omitted.

Areas 30a, 30b, and 30
Since the display processing in d and the area 30e is a conventionally known technique, its description is omitted.

FIG. 4 shows a flowchart of a page stack display processing routine for realizing the display of the page stack in the area 30b.

Here, the constants and variables used in the page stack display processing routine shown in the flowchart of FIG. 4 are as follows: constant ΔPX = offset in X direction between pages ΔPY = offset in Y direction between pages ΔS = page stack Offset in the X direction PW = Page display width in page stack PH = Page display height in page stack PC = Page number of page currently displayed in document (“1” in the initial state after power-on) The page number of the selected page is set when the page of the page stack is selected by the sedentary input device 14.) PCCOL = background color for displaying the page of which the page number is PC Variable SX = X coordinate of page stack display currently being processed P = Current page being processed Page number in the page stack PX = lower left corner display position X coordinate of the page in the page stack PY = lower left corner display position Y coordinate of the page in the page stack S = page stack being currently processed SS = page stack being currently processed Number of pages included PFIN = Total number of pages in already processed page stack PG = Page number in the document of the page currently being displayed.

In the page stack display processing routine shown in the flow chart of FIG. 4, the document editing apparatus is powered on, the memory and registers are initialized, and the instruction waiting state is entered. When the user gives an instruction to edit or display the desired document, the process for the instructed document is started.

When the page stack display processing routine shown in the flowchart of FIG. 4 is started, "0" is set in SX.
Is set, the first page stack in the page stack list is set to S, and “0” is set to PFIN (the total number of pages of the already processed page stack is initialized to “0”) (step). S402). Thus
With respect to the document to be processed, preparations are made for sequentially performing the processing from step S404 onward from the top page stack to the end page stack in the page stack list.

Furthermore, P is set to the page number in the page stack of the last page of S, and SS is set to S.
Sets the number of pages included in (step S40
4). Here, the same number of SS and P will be set, but P is sequentially changed, while SS is stored until the page stack is processed. In this way, preparations are made for sequentially performing the processing from step S406 onward from the last page to the first page in the currently processed page stack.

Next, PX is given as "SX + ΔPX × (P-
1) ”and set PY to“ △ P
Y * (P-1) "(step S4)
06), determine the position to display the page for one page in the page stack.

Then, in the area 30c on the display screen 24a of the graphics display device 24, as a page for one page in the page stack, the lower left corner position (PX, P
Y), a width PW and a height PH are displayed (step S408). That is, this rectangle means one page in the page stack.

Next, PFIN + P is set in PG, and the page number in the document of the page currently being displayed is calculated.

Then, it is determined whether or not PG and PC match (step S410). When it is determined that P and PC match in step S410, the display is performed in step S408 immediately before step S410. The inside of the rectangle is filled with the color shown in PCCOL (step S4).
12). As a result, the page in the page stack corresponding to the page currently processed and displayed in the area 30e in the document is displayed in a display mode different from other pages in the page stack (FIG. 2).
In the example shown in, the page corresponding to the “11” page of the document in the page stack 30c-3 is the PC.
It is displayed by being painted in the color shown in COL. ).

When the processing in step S412 is completed, the process proceeds to step S414, and in step S410, P and P
Also when it is determined that C does not match, step S41
Proceed to 4.

In step S414, it is determined whether or not P is "1". If it is determined in step S414 that P is not "1", it is not processed in the page stack currently being processed. Since the page remains, P
Is decremented by "1" (step S416), the process then returns to step S406, and the process is repeated until the process for all pages in the page stack currently being processed is completed.

On the other hand, if it is determined in step S414 that P is "1", there is no unprocessed page remaining in the currently processed page stack, and the currently processed page stack is in the currently processed page stack. Since the processing for all the pages has been completed, the process proceeds to step S418 and S
Determines whether it is the last page stack in the page stack list, and if S is determined not to be the last page stack in the page stack list in step S418, it is not processed for the document to be processed. Since the page stack remains, S is updated to the next page stack that is currently being processed, SX is updated by adding ΔS, PFIN is set to PFIN + SS, and the total pages of the already processed page stack are set. After updating the number (step S420), the process returns to step S404, and the process is repeated until the process for all page stacks of the document to be processed is completed.

On the other hand, if S is determined to be the last page stack in the page stack list in step S418, there is no page stack that has not been processed for the document to be processed, and therefore, the process of this flowchart is executed. The process ends.

As described above, when the user gives an instruction to edit or display a desired document by an operation of an operator (not shown), the page stack display processing routine shown in FIG. 4 is started as processing relating to the instructed document. Then, the process of displaying the page stack in the area 30c on the screen of the graphics display device 24 is performed.
Even when an arbitrary page is selected as a page to be processed from the page stack displayed in c, the page stack display processing routine shown in FIG. 4 is started and the area 30c on the screen of the graphics display device 24 is displayed. The process of updating the display of the page stack is performed. The page selection process will be described with reference to the example shown in FIG.

First, when a page selection operation is performed using the coordinate input device 14, a coordinate value indicating a page to be selected in the page stack is designated. For example, as shown in FIG. 5A, a rectangle corresponding to page number 7 in the document is filled in the area 30c, and page number 7 in the document is written in the area 30e.
When the content corresponding to is displayed, by operating the coordinate input device 14 (when the mouse is used as the coordinate input device 14, click the button of the mouse). When a page selection operation for selecting is selected, a coordinate value indicating a page to be selected in the page stack (page number 3 in the page stack) is designated. At this time, FIG.
As shown in FIG.
When a rectangle corresponding to the page (page number 3 in the page stack) selected by the operation is marked (in the example shown in FIG. 5B, it is marked with “x”), the selection is made. Easy to identify pages.

Next, the page in the page stack to be selected is searched from the coordinate values designated above, and the constant PC used in the flowchart of FIG.
A page search result (“3” in the example shown in FIG. 5) in the document of the page to be selected is set.

Then, the page stack display processing routine shown in the flowchart of FIG. 4 is executed to display the entire page stack in the area 30c. As a result, the third page in the document to be selected is painted (see area 30c in FIG. 5C).

Further, the search result of the page in the document of the page to be selected (in the example shown in FIG. 5,
"3". ), The page in the corresponding document (in the example shown in FIG. 5, “third page”) is obtained, and the page in the document is displayed by the in-document page display device 20 (in the example shown in FIG. 5, , "Third page") is displayed (FIG. 5C).
Area 30e). Since the process of displaying the page in the document is a known technique, detailed description thereof will be omitted.

Next, the processing for dividing the page stack displayed in the area 30c will be described.

That is, when an operation of the coordinate input device 14 is performed to specify an arbitrary page stack and an operation of instructing the division of the page stack with an arbitrary page of the specified page stack as a division position, the coordinate input device 14 is operated. Indicates a division instruction coordinate value indicating a page in the page stack designated as the division position.

Then, the page stack to be divided and the page position where the page stack should be divided are calculated from the division instruction coordinate values specified above, and the page stack list before the division is calculated based on this. Update the page stack list.

Specifically, page stack list SL = {S (1), S (2),
..., S (K), ..., S (M-1), S (M)}-division target page stack SK = S (K) -division target page stack 2 after division Page stack of one of the two page stacks (one located on the left side of the area 30c): SA-The back of two page stacks after the division of the page stack to be divided (area 30c) (The one located on the right side in), the first page number of SB is SB, and the updated page stack list after division is SL ′. First, SA is calculated based on SL, SK, and J. , S
Create B as follows. That is, SA = {P (1), ..., P (J-1)} SB = {P (J), ..., P (N) is obtained.

Next, SL 'is created as follows. That is, SL '= {S (1), ..., S (K-1), SA, S
B, S (K + 1), ..., S (M)} are obtained.

Then, the page stack display processing routine shown in the flowchart of FIG. 4 is executed for the page stack shown in SL 'obtained above, and the area 30c is displayed.
In, processing of displaying the entire page stack is performed.

Next, the process of merging the page stacks displayed in the area 30c will be described.

That is, by operating the coordinate input device 14, an arbitrary page stack is designated as the merge source page stack, and an arbitrary page stack is designated as the merge destination page stack, and the designated merge source page stack is designated. When the operation for instructing page merge is performed, that is, after the page stack of the specified merge destination is merged, the coordinate input device 14 instructs the merge destination page stack instruction coordinate value indicating the page stack of the merge destination. At the same time, the coordinate input device 14 instructs the merge source page stack instruction coordinate value indicating the page stack of the merge source.

Then, the page stack of the merge source and the page stack of the merge destination are searched from the merged page stack designated coordinate value and the merge source page stack designated coordinate value specified above, and based on this, before the merge. The page stack list of is updated to the page stack list after the merge.

Specifically, page stack list SL = {S (1), S (2),
..., S (M)}-Merge original page stack SK = S (K) = {PK
(1), ..., PK (NK)}-Merging destination page stack SJ = S (J) = {PJ
(1), ..., PJ (NJ)}-Page stack after merging the merge source page stack and merge destination page stack: SA-Updated page stack list after merge: SL ' , SL, SK, SJ to create SA as follows. That is, SA = {PJ (1), ..., PJ (NJ), PK
(1), ..., PK (NK)} is obtained.

Next, SL 'is created as follows. That is, SL '= {S (1), ..., S (K-1), S (K +
1), ..., S (J-1), SA, S (J + 1), ...
.., S (M)} is obtained.

In the page stack merging process described above, the case of "K <J" has been described.
The same applies to the case of “K> J”.

In the page stack merging process described above, the merge source page stack is merged at a position immediately after the merge destination page stack, but, conversely, the merge is performed at a position immediately before the merge destination page stack. The original page stacks may be merged.

Then, with respect to the page stack shown in SL 'obtained above, the page stack display processing routine shown in the flowchart of FIG.
In, processing of displaying the entire page stack is performed.

Next, the processing for moving the page stack displayed in the area 30c will be described.

That is, by operating the coordinate input device 14, an arbitrary page stack is designated as a page stack to be moved and an arbitrary page stack is designated as a page stack to be moved, and the designated page stack to be moved is designated. When the operation for instructing the movement of the page stack is performed, that is, immediately before the specified destination page stack, the coordinate input device 14 instructs the coordinate value indicating the page stack to be moved and the coordinate input is performed. The device 14 indicates the coordinate value indicating the page stack of the movement destination.

Then, the page stack to be moved and the page stack to be moved are searched from the coordinate values designated above, and based on this, the page stack list before the move is updated to the page stack list after the move. To do.

Specifically, page stack list SL = {S (1), ..., S
(K), ..., S (J), ..., S (M)}-Move target page stack SK = S (K) -Move destination page stack SJ = S (J) (position immediately before SJ SK is moved to.) ・ Updated page stack list after movement: If SL ', first, SL' is calculated based on SL, SK, and SJ.
Is created as follows. That is, SL '= {S (1), ..., S (K-1), S (K +
1), ..., S (J-1), S (K), S (J), ...
.., S (M)} is obtained.

In the above description, the movement target page stack is moved to the position immediately before the movement destination page stack, but on the contrary, the movement target page stack is moved to the position immediately after the movement destination page stack. You may move.

Then, with respect to the page stack shown in SL 'obtained above, the page stack display processing routine shown in the flowchart of FIG.
In, processing of displaying the entire page stack is performed.

The process of moving the page stack described above is executed only when the document editing device permits the document editing device not to be sorted in page number order.

Further, the processing result of the above-mentioned processing concerning division, merging and movement of the page stack is stored in the storage device 10.
And the document stored in the storage device 10 is updated.

As described above, according to the document editing apparatus of the present invention, the amount and the positional relationship of the document to be processed are displayed by the page stack. Therefore, the user can display the amount and the positional relationship in the document. In addition to being able to visually and intuitively grasp, the page stack can be arbitrarily divided, merged, or moved by the user's operation, so while grasping the overall structure, you can create a document with a free structure. You will be able to create.

The document editing apparatus according to the present invention described above may be modified as follows. (1) As shown in FIG. 6, page numbers may be added to the page stack displayed in the area 30c.

In this case, the data structure of the document is the same as that shown in FIG.
As shown in, the page stack is set so that the first page of the page stack in the page stack list is arranged in ascending order of the page numbers of the pages in the corresponding document,
The pages in the page stack are set to be arranged in ascending order of page numbers of the pages in the corresponding document in the page stack.

That is, the columns of the page stack in the page stack list are arranged in the ascending order of the page numbers in the documents included in the page stack, and the columns of the pages in one page stack are the documents. Make sure the pages in are sorted in ascending order of page numbers.

For example, it has 10 pages and has four page stacks (page stack A (three pages of page number "1" to page number "3"), page stack B (page number "4"). 1 page), page stack C (4 pages of page number "5" to page number "8") and page stack D (2 pages of page number "9" to page number "10") ) Is a page stack list = {page stack A, page stack B, page stack C, page stack D} page stack A = {page 1, page 2, page 3} page stack B = {page 4 } Page stack C = {page 5, page 6, page 7,
Page 8} Page stack D = {Page 9, Page 10}.

As the processing for displaying the page number on the page in the page stack, the following processing is performed immediately after step S408 of the flowchart shown in FIG. That is, as shown in FIG. 8, PW = page width and ΔPY = offset between pages in the Y direction are calculated, and the value of the width PNW of the area for displaying the page number is calculated. That is, PW is set to PNW.

Next, the height P of the area for displaying the page number is set.
Calculate the NH value. That is, ΔPY is set in PNH.

Then, the page number P is displayed at the uppermost position in the page within the page stack by a method of fitting the rectangular area having the width PNW and the height PNH.

In step S412 of the flowchart shown in FIG. 4, the rectangle (pages in the page stack) is set to P.
When filling with the color of CCOL, the page number displayed in the rectangle (page in the page stack) to be filled may be inverted. In other words, the page number may be displayed in white,
Thereby, even if the rectangle (pages in the page stack) is filled, good visibility of the page number can be ensured. (2) For each page in the page stack displayed in the area 30c, the data of the corresponding page in the document may be displayed as shown in FIG.

In this case, the following processing is performed immediately after step S408 in the flowchart shown in FIG. That is, as shown in FIG. 10, DW = width of page data in document DH = height of page data in document PW = page display width in page stack PH = page display height in page stack , The width reduction ratio SW is calculated. That is, SW: = PW / DW is calculated.

Next, the height reduction ratio SH is calculated. That is, the calculation of SH: = PH / DH is performed.

Then, the reduced display magnification SP of the page is calculated. That is, SP: = MIN (SW, SH) is calculated, SP, whichever is smaller, SW or SH is set, and the page display device 20 in the document causes the reduced display magnification of the page as the calculation result. The SP is used to display the data of the corresponding in-document page in the pages in the page stack. (3) In the page stack displayed in the area 30c, as shown in FIG. 11, a reference page (in FIG. 11, a rectangle whose outline is indicated by a broken line and a page number such as “ref-3”) is displayed. “Ref-” is added before.) May be displayed.

Here, the reference page is not an actual page (actual page), but a page set for referencing the actual page (actual page) when a document is edited.

When displaying the reference page, it is necessary to adopt the data structure shown in FIG. 12 as the data structure of the document, and in detail, the following data structure is provided.

Document: = {Document contents, page stack list, page pointer in currently displayed document} Document contents: = {Page in document 1, ...
... Page in document m} Page stack list: = {Page stack 1, ...
., Page star n} page stack: = {page 1, ..., page k} page: = real page | reference page * real page: = pointer pointing to page in document one-to-one reference page == A pointer to a page in the document.

The “real page” and the “page in document” included in the page stack list have a one-to-one correspondence relationship.

Next, the process of displaying the reference page in the area 30c will be described. The process of step S408 in the page stack list display process routine shown in the flowchart of FIG. 4 is described as follows. In the case of, the broken line indicates the position of the lower left corner (PX, P
Y), a width PW, and a height PH are displayed. It can be replaced with ".

In the above description, the real page is displayed by the solid line and the reference page is displayed by the broken line. However, the present invention is not limited to this, the background color may be changed,
Other display attributes may be changed to distinguish the real page and the reference page, such as changing the color of the rectangular outline.

Next, the processing for creating a reference page from a real page will be described.

That is, by operating the coordinate input device 14,
When the "reference page creation" is instructed and the operation for instructing the real page from which the reference page is created is performed, the coordinate input device 14 specifies the coordinate value indicating the page in the stack that is the source of the creation. . Then, the reference page is created based on the coordinate value of the real page that is the source of the reference page creation specified above, and the page stack list before creating the reference page is updated to the page stack list after creating the reference page. .

Specifically, page stack list SL = {S (1), ..., S
(K), S (K + 1),
..., S (M)}-Real page P (J) Note that P (J) is included in S (K).

• Document page pointed to by P (J) = DPJ • Reference page pointed by DPJ = RP • Page stack consisting of only RP = RS • If page stack list after creating reference page = SL ', first , The page in the document pointed to by the real page P (J) is set in the DPJ, the reference page pointed to by the DPJ is created and set in RP, and the page stack RS consisting of only the reference page RP is created. Then, based on RS, SL 'is created as follows. That is, SL '= {S (1), ..., S (K), RS, S (K
+1), ..., S (M)} are obtained.

Then, the page stack display processing routine shown in the flowchart of FIG. 4 is executed for the page stack shown in SL 'obtained above, and the area 30c is displayed.
In, processing of displaying the entire page stack is performed.

Next, the process for deleting the reference page will be described. The operation of the coordinate input device 14 instructs "delete reference page" and also the operation for instructing the reference page to be deleted. Then, the coordinate input device 14 instructs the coordinate value indicating the reference page to be deleted.

Then, the page P to be deleted is obtained based on the coordinate value of the reference page to be deleted specified above. If P is a real page, an appropriate error message is displayed and the data Do not update. On the other hand, if P is a reference page, the reference page is deleted, and the page stack list before the reference page is deleted is updated to the page stack list after the reference page is deleted.

Specifically, page stack list SL = {S (1), ..., S
(K), ..., S (M)}-Page stack S (K) = {P (1), ..., P
(J), ... P (N)}-Reference page P (J) Note that P (J) is included in S (K). If the page stack list after the reference page is deleted = SL ′ and the page stack after the reference page is deleted = SK ′, first, from the page stack S (K), P
A page stack SK 'from which (J) has been removed is created as follows. That is, SK '= {P (1), ..., P (J-1), P (J +)
1), ... P (N)} If SK ′ does not include any page, SL ′ = {S (1), ..., S (K−1), S ( K +
1), ..., S (M)}, and if SK ′ includes one or more pages, SL ′ = {S (1), ..., S (K−1), SK ',
S (K + 1), ..., S (M)}.

Then, the page stack display processing routine shown in the flowchart of FIG. 4 is executed for the page stack shown in SL 'obtained above, and the area 30c is displayed.
In, processing of displaying the entire page stack is performed.
