DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic document processing apparatus, and more particularly, to an electronic document processing apparatus having a characteristic document structure.

[0002]

2. Description of the Related Art In today's offices, office automation is in progress to improve business productivity.
In addition, the number of documents (office documents) created by a word processor, a personal computer, and the like is increasing rapidly. The documents are frequently exchanged using a floppy or an electric communication means. Moreover, recent documents are often multi-media documents that include not only character information but also graphic or image information. Since these documents were created without permission by each word processor or word processing software of each personal computer, etc., there was no compatibility between the documents, such as those created on one side could not be displayed or modified on the other side. That is a big problem.

[0003] Against this background, in order to freely exchange and re-edit any document,
ISO (Internatinal Organization for Standardizat)
ion, International Organization for Standardization) and CCITT (International T)
The elegraph and telephone Consultative Committee, the International Telegraph and Telephone Consultative Committee, is working on standardization of the document structure and transfer format. The standard of the document structure and transfer format is ODA (Office / Open do
cument Architecture, open-ended document system).
In the ODA, a logical configuration of a document, a so-called logical structure (hereinafter, referred to as “document structure”) is clarified.

A document in the ODA has a document structure in which a plurality of basic structural elements (so-called “basic logical objects”) each having an identifier assigned thereto, and a specific document content associated with each of the basic structural elements. And element contents. The document structure of the ODA includes a plurality of basic structural elements (so-called “basic logical objects”), and one complex structural element (so-called “composite object”) is obtained by collecting a predetermined number of the basic structural elements. Is configured, a higher-level composite structural element is configured from a predetermined number of the composite structural elements collected,
There is also a document structure having a so-called hierarchical tree structure.

[0005]

By the way, conventionally, there are many documents having the tree structure even in ordinary paper documents. For example, LAN (Local Area Network,
An operation manual (document) such as an EWS (engineering workstation, that is, a terminal device) or a personal computer of a local area network includes a document having the tree structure. An example of the document structure is shown in FIG. FIG. 18 shows an “operation manual” as an example of the document having the hierarchical tree structure. In FIG. 18, one composite structural element (chapter) is composed of a predetermined number of basic structural elements (sections), and a document structure of an operation manual is composed of a predetermined number of the composite structural elements (chapter). Have been. One element content (that is, specific document content) is associated with each basic structural element (section). Each element content is provided with an element identifier indicating which basic structural element (section) it corresponds to.

[0006] Among the users who use the operation manuals such as the EWS, there are users having basic knowledge (users of level 1), users having intermediate knowledge (users of level 2), and advanced users. There are various levels of users, such as users with knowledge (level 3 users). The required operation description contents differ depending on the user's level for each user. In such a case,
For example, an intermediate user and an advanced user may not need an operation explanation at an intermediate level or an advanced level, and an advanced user at a level 3 may not need an operation instruction at an intermediate level or an intermediate level. Further, when the operation manual includes confidential operation explanation contents, the operation explanation contents must be kept secret except for some qualified persons (for example, a user registered as a level 4 qualified person). Occurs.

In the case described above, each level 1 of the user,
Depending on 2,3,4, for beginner, intermediate, advanced,
By creating an operation manual for partially qualified persons, an operation manual including only the contents necessary for each user, that is, an easy-to-use operation manual with less unnecessary contents can be obtained. However, in that case, there is a problem that the number of operation manuals increases and manual creation costs increase. Further, when the operation manuals are made of paper, there is a problem that a large space is required for storing the operation manuals.

Further, if all the operation explanation contents for beginner, intermediate and advanced users are included in one operation manual, such operation manual has many unnecessary explanation parts for each user, and is inconvenient to use. There was a problem of becoming something. This problem is a problem that cannot be solved simply by electronically documenting the operation manual.

The above description relates to the operation manual. However, even if the document is other than the operation manual, a problem similar to the case of the operation manual may occur. For example, in a transaction document,
Element contents (section contents) associated with each basic structural element (section) can be understood without general knowledge such as general non-confidential matters (level 1 element contents) and accounting that all users can read. There is no professional non-confidential matter (Level 2 element content) and low-level confidential matter (Level 4 element content, in this case, Level 3 element that can be read by users of Level 4 or higher set in the company) There is a case where contents can be classified into high-level confidential matters (level 5 element contents) that can be read by a user of level 5 or higher set in the company.

In such a case, in order to create a document relating to the transaction with ease for each user,
The following four types (a) to (d) must be created separately. (a) a document describing the general non-confidential matter (level 1 element content) that can be read by all users; (b) the professional non-confidential matter (level 2) that can be read by all users.
(C) a document that describes the low-level confidential matter (level 4 element content) that can be read by users of level 4 or higher set in the company, and (d) a document that is set in the company A document in which the high-level confidential matter that can be read by a user of level 5 or higher is described. In such a case, the number of documents increases as in the case of the operation manual. .

In view of the above circumstances, an object of the present invention is to provide an electronic document processing apparatus capable of easily reading a document composed of element contents required by a user.

[0012]

In order to solve the above-mentioned problems, an electronic document processing apparatus according to a first aspect of the present invention provides a document structure comprising a basic structural element and a composite structural element obtained by collecting the basic structural elements. In an electronic document processing apparatus that processes a structured document represented by element content that is specific document content associated with each of the basic structural elements, a level identifier representing a displayable level is associated with each of the element contents. Storage means for storing, level specifying means for performing an operation of specifying a display level, and element contents having a level identifier corresponding to the display level specified by the level specifying means are selected and displayed for each basic structural element Document display means.

In the first invention, when the user does not specify a level at the time of reading the electronic document,
It is possible to read out element contents to which a predetermined level identifier specified by a preset default value (initial setting value, for example, a value specifying a level identifier corresponding to level 1) is read. is there.

Further, in the electronic document processing apparatus according to the first aspect of the present invention, in the document structure, one composite structural element is formed from a collection of the basic structural elements, and a higher-order one from the collection of the composite structural elements. A composite structural element is composed,
It can be configured to have a hierarchical tree structure. It is also possible to configure so that the level can be specified for each branch point of the electronic document having a hierarchical tree structure in the document structure. In this case, different levels are specified for the upper branch point and the lower branch point. In this case, the element content corresponding to the level specified at the lower branch point can be read out preferentially.

An electronic document processing apparatus according to a second invention of the present application is:

A displayable level specifying means (M8) for specifying a possible level; and a selection prohibiting means (M71) for prohibiting selection of an element content provided with a level identifier higher than the displayable level. And

The "displayable level specifying means (M8)" of the third invention is means for restricting the display of element contents of a predetermined level according to the qualifications of the user.
For example, a memory storing a table in which a user identification number or a password and a displayable level corresponding to the user identification number or the password are recorded, and a user identification number or a password input when the user starts using the electronic document processing apparatus. Correspondingly, a device for reading a displayable level corresponding to the user's qualification from the table can be configured.

[0018]

According to the first aspect of the present invention having the above-described structure, a level identifier representing a displayable level is stored in association with each of the element contents, and the level identifier corresponding to the specified display level is operated in accordance with the operation of the level designating means. The element content having the level identifier to be selected is selected and displayed for each basic structural element.

Further, in the electronic document processing apparatus according to the first aspect of the present invention having the above-mentioned configuration, as shown in FIG. 3, the document structure is such that one composite structural element is obtained by collecting a predetermined number of the basic structural elements. When a hierarchical tree structure is formed in which a higher-level composite structural element is formed from a predetermined number of the composite structural elements, the level of element content to be displayed is designated for each branch point of the tree structure It is also possible to configure so that it can be performed. In this case, when a level is specified at a predetermined branch point (for example, “Chapter 1” in FIG. 3), a basic structural element (“Chapter 1 Chapter 1”) belonging to a lower level of the branch point (“Chapter 1”) Section, Chapter 1, Section 2)), it is also possible to specify at one time the level of all element contents, and it is also possible to specify a higher branch point (for example, "Operation Manual" in FIG. 3). When a different level is specified between the lower branch point (for example, “Chapter 1” in FIG. 3) and the lower branch point (for example, “Chapter 1” in FIG. 3), the element content corresponding to the level specified at the lower branch point (“Chapter 1”) is It can be configured to be read out preferentially.

In the electronic document processing apparatus according to the second invention having the above-described configuration, a readable level identifier is assigned to the composite structural element and stored. Then, when the display level is designated by the level designating means (K), the contents of the composite structural element having the level identifier corresponding to the designated display level are selected. Then, the element content is displayed for each basic structural element included in the selected composite structural element.

Further, the electronic document processing apparatus according to the third invention having the above-described configuration includes a displayable level specifying means for specifying a displayable level corresponding to the qualification of a user who is performing an operation of reading an electronic document; Element content selection prohibition means is provided for prohibiting the selection of element contents to which a level identifier higher than the displayable level is assigned, so that element contents requiring confidentiality are read only by users having a predetermined read qualification level or higher. I am not able to do it. Therefore,
The electronic document processing apparatus according to the third aspect can perform security management of the electronic document for each element content.

The document structure has a hierarchical tree structure in which one composite structural element is composed of a predetermined number of basic structural elements, and an upper composite structural element is composed of a predetermined number of the composite structural elements. have. Further, the content of the basic structural element includes a plurality of element contents corresponding to one basic structural element, and each element content includes the content of any of the basic structural elements among the plurality of basic structural elements. An element identifier for specifying the presence of the element and a level identifier indicating the level of the content of each element are provided.

FIG. 3 is a diagram showing a specific example of a structured document, that is, an operation manual. This operation manual is based on ODA (Office / Open document Architecture,
It has a logical structure (that is, a document structure) standardized in the release-of-business document system, and the document structure is a hierarchical tree structure as shown in FIG. That is, this operation manual is composed of Chapter 1, Chapter 2, and Chapter 3, and Chapter 1 is composed of Chapter 1, Section 1 and Chapter 1, Section 2. Also, Chapter 2 is composed of Chapter 2, Section 1 and Chapter 2, Section 2, and Chapter 3 is composed of Chapter 3, Section 1.

In the case of this operation manual, Chapter 1
, Chapter 1, Section 2,..., Chapter 3, Section 1, etc. are basic structural elements ("basic objects" in the ODA).
These are node identifiers Y01010101 (Chapter 1, Section 1), Y01010201 (Chapter 1, Section 2),.
Y03010101 (Chapter 3, Section 1) and the like. Although the node identifier is different from the element identifier, they will be described later with reference to FIG. Also, the first chapter is a composite structural element obtained by collecting the basic structural element represented by the node identifier Y01010101 (Chapter 1, Section 1) and the basic structural element represented by the identifier Y01010201 (Chapter 1, Section 2). (The OD

It is represented by 01. Note that the reason why the node identifiers of the first, second, and third chapters are not Y01, Y02, and Y03 but Y0101, Y0201, and Y0301 is based on the data structure of FIG. 9 described later.

In FIG. 3, for example, the basic structural element Y
There are four types of element contents associated with 01010101 (Chapter 1, Section 1), and each of the element contents has the basic structural element Y01010101 (Chapter 1, Section 1).
The same (common) node identifier Y0101010101 indicating that it is associated with the lower order of the clauses is added to the upper digit. Further, the lower digits are identifiers 04 (corresponding to level L4) to 01 (corresponding to level L1) corresponding to the level.
Corresponding to).

When a structured document as shown in FIG. 3, that is, an operation manual is stored in the electronic document processing apparatus U1, when reading the document, for example, the level L
When 2 is specified, the basic structural elements Y01010101, Y of the document structure of the document "operation manual"
A document in which the element content of the level L2 is incorporated is created and displayed in 0101201,. However, the basic structural element Y020201001 (Chapter 2, Section 2)
Since there is no element content of the level L2 in the element content corresponding to, a document incorporating the element content of the level 1 is displayed.

FIG. 4 shows a network system U having the functions (see FIG. 1) of the electronic document processing apparatus U1 of the first embodiment of the present invention shown in FIG. In FIG. 4, a network system U includes a LAN (local area network) 1 connected by a router R and an LA.
N2.

A file server FS, a print server PS, and an EWS (engineering workstation) are connected to the LANs 1 and 2, respectively. Since the area of the paper is limited, the LAN
Although only one EWS is shown as a device connected to the LAN 2, other devices other than those shown are also connected to the LAN 1 and the LAN 2. The file server FS
Is a computer (central processing unit), a ROM (read only memory), a RAM (random access memory), an I / O (input / output interface), etc., a computer main body, a keyboard, a display, and a hard disk. Have. The print server includes a computer body, a keyboard, a display, a hard disk, and a printer, and the EWS includes a computer body, a keyboard, a display, a hard disk, and a mouse. .

The EWS has a document processing function (document creation,
And a document created and edited by EWS is stored in the hard disk of the file server FS. Also,
The hard disk of the file server FS stores a table having a user password and a level value set in accordance with the password. The level value in this table is set to 3 for general users, and is set to 4 for users who have special qualifications who are allowed to view confidential documents. Then, a user registered in the network system U can access a document stored in the hardware of the file server FS from each EWS according to a level value (qualification) set corresponding to his / her password. (Described later). An electronic document processing apparatus U having the functions shown in FIG. 1 by each of the EWS and the file server SF.
The EWS ROM stores a program for realizing the functions of the units M1 to M7 of the electronic document processing apparatus shown in FIG.

Next, the operation of the network system U having the above configuration will be described. FIG. 5 is a flowchart showing a flow when the program stored in the EWS is executed. In FIG. 5, when the use of the EWS is started, it is determined in a step S1 whether or not a password registered in the network system U has been input. If no (N), the process of step S1 is repeated. When the user enters the network system U
Enter the password registered in step S1
, And the process moves to the next step S2.

In step S2, a displayable level value corresponding to the input user password is read out from a table in which the password stored in the file server FS and the displayable level corresponding to the password are stored. , The user's available level value La (= 3 or 4) is set. That is, La = 3 is set for general users, and La = 4 is set for users who have special qualifications. Next, in step S3, it is determined whether the document processing mode has been selected. If no in step S3, the mode shifts to another mode, and if yes, the process shifts to step S4.

In step S4, it is determined whether a new document is to be created. If yes, proceed to step S12; if no, proceed to step S5. Here, first, the case of YES in step S4, that is, the case of creating a new document will be described. If yes in step S4, a document editing screen is displayed in step S12. Next, a document is displayed in step S13.
The document displayed here is a document in which characters have not been input if the result of step S4 is YES (in the case of creating a new document). After the document is displayed in step S13, the process proceeds to step S14.

In step S14, it is determined whether a document has been input. If the answer is yes, the data is stored in the memory in step S15, and the process returns to step S13. If the answer is no in step S14, the process moves to step S16. Step S
At 16, it is determined whether or not identifier data has been input.

Next, a method of inputting the identifier data will be described. An “operation manual” as shown in FIG. 6 (A), that is, after the document is created or during the creation, for example, at the beginning of the first line of the document (the line described as “operation manual”), the control key + Y Press (ie press Y while holding down the control key)
Then, a node identifier input image (see FIG. 6B) is displayed in the upper column of the screen, and the node identifier input mode is started. Beginning of the first line of the document (head of sentence), as is the case now
When the node identifier input mode is started in a state where the cursor is located at Y, Y = [is automatically displayed on the node identifier input image. In this embodiment, the brackets [] are used as symbols to indicate the start of the document. When the return key is pressed in this state, the start position of the cursor is stored as the start position of the document. For example, as shown in FIG. 7, data "YS" for indicating that the cursor position is the start position of the document.
(S is the first letter of START) is stored corresponding to the cursor position. At this time, the node identifier input image shown in FIG. 6 is deleted at the same time.

When the cursor is placed at the end of the sentence and the node identifier input mode is started, Y =] is automatically displayed on the node identifier input image. When the return key is pressed in this state, it is stored that the end position of the sentence where the cursor is located is the end position of the document. To indicate the end position of this document, for example, as shown in FIG.
Data "YE" (E is the first letter of END) is stored.
The data YS and YE can be automatically stored at the beginning and end of the sentence without inputting the node identifier.

Next, when the node identifier input mode is started (when the control key + Y is pressed) with the cursor positioned at the beginning of the line in which "Chapter 1" is described, the node identifier input image is displayed. Is automatically displayed. In this state, if 入 力 is input after Y = [and the return key is pressed after Y = [｛is displayed, the beginning of the line where the cursor is located is the position of the beginning of the first chapter of the document. Is stored. In order to indicate the start position of the first chapter, for example, the data “Y010
1S "is stored (see FIG. 7).

Next, when the node identifier input mode is started in a state where the cursor is located at the beginning of the "section 1" of "Chapter 1", that is, the line in which the element content corresponding to the basic structural element is described ( When the control key + Y is pressed), Y = [｛is automatically displayed on the node identifier input image. In this embodiment, since it is determined that the element contents corresponding to the basic structural elements are enclosed in parentheses (), (
Pressing the return key after [｛(is displayed. Then, the start position of the line where the cursor is located is the start position of the first chapter and the first section of the document. For example, data “Y01010101S” is stored to indicate the start position of one section (see FIG. 7).

Next, when the node identifier input mode is started in a state where the cursor is located at the beginning of the line in which the "section 2" of "chapter 1" is described (when the control key + Y is pressed) , Y =
[｛Is automatically displayed. In this state, Y = [｛
Later, when (is input and Y = [押 す (is displayed and the return key is pressed, it is stored that the beginning of the line where the cursor is located is the start position of the first chapter and second section of the document. For example, data “Y01010201S” is stored to indicate the start position of the first chapter and the second section (see FIG. 7). Is automatically stored as the end position of the first chapter and the first section, that is, the data “Y0101010” corresponding to the end of the line before the start position of the first chapter and the second section.
1E "is stored (see FIG. 7). Then, the "Y0
The node identifier “Y01010101” is automatically added to the documents between “1010101S” and “Y01010101E”, that is, the element contents of “section 1” of Chapter 1.

When the node identifier data is input as described above, the structure of this document can be shown in FIG. Although not shown here, in actuality, the data for storing the document structure and element contents include, for example, the number of characters in one line,
There is also data for storing line spacing, character attributes, and the like. In this way, when a node identifier is assigned to each element content, the level identifier L = 1 is automatically set to the element content. When it is desired to reset the value of the automatically set level L = 1 to another value, for example, the “1st level” in Chapter 1
If the user wants to set the value of the level value L of the element content of the clause to 2, the following operation is performed. First, when the control key + L is pressed with the cursor at the beginning of the line in which the "section 1" of Chapter 1 is described (that is, L is pressed while pressing the control key), as shown in FIG. Then, the level identifier input image is displayed in the upper column of the screen, and the level identifier input mode is started.

When the level identifier input mode is started (when the control key + L is pressed), L = 1 is automatically displayed on the level identifier input image. In this state, when 2 is input from the numerical keys, L = 2
Is displayed. When the return key is pressed in a state where L = 2 is displayed, the level L of the element content of the first chapter and the first section starting from the position where the cursor is located is set to L = 2.

If the determination in step S16 is yes (that is, if there is an identifier data input), the data is stored in the memory in step S17, and the process returns to step S13. If no in step S16, the process moves to step S18. In step S18, it is determined whether the document processing mode end key has been pressed. If no, the process returns to step S14, and if yes, the process proceeds to the next step S19. In step S19, it is determined whether the rewriting or non-rewriting of the document has been selected. If no, step S19 is repeatedly executed. If the answer is yes, the process moves to the next step S20.

In step S20, step S19 is performed.
Execute the process selected by. If non-rewriting is selected in step S19, the edited document is discarded, and if rewriting is selected, the edited document is stored. Then, the document processing ends.

The document to be stored in step S20, that is, the edited document (operation manual)
Has a structure as shown in FIG. The data structure for storing this structured document is shown in FIG.

In FIG. 9, both the composite structural element and the basic structural element are treated as nodes, and are stored as node structure data. The node structure data is
The two pointers are linked by a lower node pointer and a lower level pointer. The lower node pointer points to the highest level node of the node immediately below. The lower level pointer points to a lower level node. If there is no node to be pointed to, both pointers are put in a nil value to indicate that there is no node to be pointed to.

The node identifier is for uniquely identifying the node in the document processing system.
The element identifier is an identifier common to a plurality of element contents corresponding to the same basic structure element. For example, in FIG. 9, the node data in the third block from the top, that is, the basic structural elements in Chapter 1, Section 1, correspond to the node data of the levels L4 to L1 shown in the blocks 4 to 7 from the top, that is, the element contents. ing. Each of the above element contents is 3
Lower node pointer Y010101010 of block
The upper 7 digits of the node identifier are common (Y0101010101). Therefore, in the case of the element content of the basic structural element in Chapter 1, Section 1, the element identifier is the upper seven digits of the node identifier.
The level identifier stores the level data of each node. The node data includes data relating to the node, for example, "Chapter 1 ... Chapter name ...". In particular, the lowest-order node contains, as its node data, the contents of the basic structural element, that is, document data (element contents).

Next, FIG. 9 will be described specifically. FIG.
It is a data structure of the structured document (operation manual) shown in FIGS. Although it is possible to create a plurality of levels for the whole of the operation manual or for a composite structural element such as each chapter therein, in the example of FIG. 3, there are a plurality of levels for the entire operation manual. No, only the level L1 exists. In addition, each chapter that is a composite structural element (“Chapter 1”, “Chapter 2”, “Chapter 3”
Is created only for level L1. FIG.
In the example, element contents of a plurality of levels L4 to L1 are created only for the element contents of the basic structural element.

In FIG. 9, the uppermost node is the entire operation manual. The entire operation manual is represented by a node identifier Y. Since the operation manual has only the level L1 as a whole, the level identifier is L1. And since there is no lower level operation manual, the lower level pointer is nil.
In addition, the title “operation manual” is stored as the node data. And the lower node pointer is the first
Y01 points to the chapter (indicating the address where the first chapter is stored), Y02 points to the second chapter, and Y03 points to the third chapter.

The identifier of the node pointed to by the lower node pointer Y01 pointing to the first chapter is Y
3, the level identifier is L1 and the lower-level pointer is nil, because in the example shown in FIG. And
The node data is, for example, “Chapter 1
... (title of Chapter 1) ... ". Since this Chapter 1 has Chapter 1 Section 1 and Chapter 1 Section 2,
The lower node pointer is Y0 which points to Chapter 1, Section 1.
Y101 pointing to 10101 and Chapter 1, Section 2
102.

Hereinafter, although the description is omitted, the structured document of FIG. 3 is stored by the data structure shown in FIG. When reading the structured document, a document composed of the element contents of the specified level Li (i = 1 to 4) is displayed.

Next, a description will be given returning to the flowchart of FIG. 5 again. If no in step S4,
That is, a case where a new document is not created will be described. If no in step S4, it is determined in step S5 whether to modify the document. If no, the process returns to step S4. If yes, the process proceeds to step S6. In step S6, the document list is displayed on the display D. A display example in that case is shown in FIG. Next, in step S7, it is determined whether a document has been selected. If no, step S7 is repeatedly executed. Then, the user clicks the mouse (see Fig. 4).
Is used to move the mouse cursor shown in FIG. 10 to select, for example, a document "operation manual".
Then, the answer is yes in step S7, and the process proceeds to the next step S8. It should be noted that document selection can also be performed using arrow keys instead of a mouse.

In step S8, a level selection screen (see FIG. 11) is displayed. The level selection screen shown in FIG. 11 includes the document structure of the document (in this case, the operation manual) selected in step S7, each basic structural element (each section), each composite structural element (each chapter), and the document. Initial value L of level L set for each whole (operation manual) =
1 is displayed. In the level selection screen shown in FIG. 11, when the value of the level L of the upper layer is input, the same value of the level L of the lower layer is automatically input. For example, in FIG. 11, if the mouse cursor is moved to the position of the level L value on the right side of the “operation manual” and a mouse button (not shown) is clicked, the state of waiting for the input of the level L value of the entire operation manual is displayed. Become. At this time, if, for example, 2 is input to the value of the level L and then executed (by moving the mouse cursor to “execute” and clicking the mouse button), the level L values of all lower layers are automatically set. Is set to 2. In this state, for example, if the value of the level L in Chapter 2 is set to 1, the lower hierarchy (Chapter 2, Section 1 and Chapter 2, Section 2
) Are all set to 1.

After the level selection screen shown in FIG. 11 is displayed in step S8, it is determined in step S9 whether a level has been selected. If no, step S9 is repeatedly executed. Then, when the user sets the value of the level L on the level selection screen of FIG. 11 and executes (moves the mouse cursor to “execute” and clicks the mouse button), the result in step S9 is YES. If the answer is yes in step S9, the process proceeds to step S10.

In step S10, it is determined whether or not the value of the selection level L (the value of the level L set in FIG. 11) is equal to or less than the displayable level value La set in step S2. If the answer is no in step S10, a message indicating that selection is not possible (the value selected in FIG. 11 is not selectable) is displayed in step S11, and the process returns to step S8. If the answer is yes in step S10, the process moves to the next step S12.
In step S12, a document editing screen is displayed.

Next, a document is displayed in step S13. The document displayed here is the document (for example, “operation manual”) selected in step S7 and the element content of the level selected in step S9 (a plurality of levels of the plurality of levels corresponding to the respective basic structural elements). The document has a selected level of element content among different element contents. Here, as the element content of the document (for example, “operation manual”) selected in step S7, the level identifier L =
In the case where only the one to which 1 has been added is stored (see Chapter 2, Section 2 in FIG. 3), L is set in step S9.
Even if a value equal to or greater than = 2 is selected, only the element content of the identifier with L = 1 is read and displayed.

Next, the process proceeds to step S14. This step S
In the case of 14 or less, substantially the same processing as in the above-described case of creating a new document (that is, in the case of YES in step S4) can be performed, but the following processing can also be performed. That is, for example, the element content (that is, the element content corresponding to the basic structural element) of the “section 1” of Chapter 1 and its level L value are rewritten, and the node identifier is not input ( That is, when the document processing is completed without changing the document structure), a plurality of element contents having different levels L are created corresponding to the same basic structure element (Chapter 1, Section 1) (Chapter 1). Will be remembered).

In this way, a plurality of element contents having different levels L are created corresponding to the same basic structural element, and a document structure in which a plurality of basic structural elements are assembled and the level corresponding to each of the basic structural elements By storing a plurality of element contents having different L in the data structure shown in FIG. 9, it becomes possible to read and display a document having the element contents of the designated level. Further, as in the first embodiment, when the displayable level is set for each user and the element contents to which the level exceeding the displayable level is assigned are not displayed, the security management of the document can be easily performed. Can be.

Next, a second embodiment of the present invention will be described with reference to FIGS. In the second embodiment, while displaying a document,
This embodiment is different from the first embodiment in which the function of replacing the element content being displayed with the element content of a different level is provided without the replacement function during the document display. For this reason,
In the second embodiment, the flowchart shown in FIG. 5 of the first embodiment is changed as shown in FIGS. 12 and 13, and the document display screen shown in FIG. 14 is slightly different from the screen shown in FIG. Is different.

Step S in the flowchart shown in FIG.
Steps 1 to S12 are the same as steps S1 to S12 in the flowchart of FIG. 5 of the first embodiment, and steps S14 to S20 of the flowchart of FIG. 13 are the same as steps S14 to S20 of the flowchart in FIG. Steps S14 to S20
Is the same as That is, the flowchart of the second embodiment differs from the flowchart of the first embodiment in that steps S23 to S26 are provided instead of step S13 of the flowchart shown in FIG.

Step S in the flowchart shown in FIG.
At 23, a content selection image is displayed with the document.
This content selection image is displayed in the lower column of the screen as shown in FIG. In the displayed content selection image, the value of the level L of the currently displayed element content corresponding to the current cursor position on the display screen, for example, L = 1, is displayed. Next, in step S24, it is determined whether or not the element content to be displayed has been selected. If no, the process proceeds to step S14, and the same processing as the flowchart shown in FIG. 5 of the first embodiment is performed. The user moves the cursor using the mouse or the like to “1” of L = 1, that is, the level L.
Is clicked and the mouse button is clicked, and for example, after inputting "2", execution is selected or the return key is pressed, and the result in the above step S24 is YES. Then, the process proceeds to step S25.

In step S25, it is determined whether the selected level value L is equal to or less than the available level value La set in step S2. In the case of YES in step S25, the element content currently being displayed is replaced with the element content of the selected level. If the answer is no in step S25, the process moves to the next step S26. In step S26,
It indicates that the element content of the level selected by the user is unreadable (not selectable). Then, the process returns to step S23.

In the second embodiment, for example, level L = 1
While displaying a document composed of the element contents of, for example, an operation manual, and reading the contents, the level L
When it is desired to read the element content of level = 2, the element content of level L = 2 can be easily read.
