Abstract

PURPOSE:To grasp the document structure with high efficiency by storing a document consisting of a hierarchized document component, and displaying the document component of the lower hierarchy than the designated hierarchy, when the document component of the higher order hierarchy is designated. CONSTITUTION:An input is supplied from a keyboard KB, and a microprocessor CPU executes various controls in accordance with a control signal stored in a ROM. In a character processor, a document having a structure consisting of three hierarchies of a header, the end of a paragraph and a sentence is stored. As for a display by a CRT, when a document component of the higher order hierarchy, for instance, the end of a paragraph is designated, a part of a sentence having the lower order hierarchy than the designated hierarchy is displayed. In such a way, the structure of a document can be understood easily, and the document processing can be executed with high efficiency.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a character processing device that displays the structure of a document.

(Prior Art) Conventionally, a device called an outline processor, for example, has been devised as a character processing device that handles document structure.

A document generally has a structure consisting of three layers: "heading", "paragraph", and one sentence. Retrieve the character string from the document memory,
It was possible to display it as a document component, such as by displaying only the first few characters of a sentence.

However, in the conventional technology, for example, "paragraph"
If you specify the display of ``paragraphs'', the entire document is processed, so all you can do is display all the ``paragraphs.''

As a result, even "paragraphs" that are not related to the heading that is currently being revised are displayed at the same time, making it difficult to understand the necessary parts due to unnecessary "paragraph" display, making it unsuitable for grasping the document structure. There was a drawback that there was no

Conventionally, a device called an outline processor, for example, has been devised as a character processing device that handles document structure.

Documents generally have a structure consisting of three levels: "headings,""paragraphs," and "sentences." It was possible to display part or all of the character strings that make up a ``sentence'', such as by retrieving a ``sentence'' from the document memory and displaying only the first few characters of the sentence.

However, in conventional technology, "headings" and
There are many sentences constituting a paragraph, and displaying all sentences without abbreviations is no different from displaying the document itself, which is not suitable for grasping the document structure. In addition, when a portion of a sentence is abbreviated, the document structure becomes easier to understand, but the content of each individual sentence is not made clear, and it becomes necessary to search for the content of that single sentence from the actual document display. there were.

[Objective] An object of the present invention is to eliminate the drawbacks of the above-mentioned conventional examples.

The object of the present invention is to provide a document storage means for storing a document, a specification means for specifying a document component in a higher hierarchy, and a method for displaying only document components in a lower hierarchy than the specified hierarchy. An object of the present invention is to provide a character processing device including a display means for displaying document constituent elements in a lower hierarchy.

The purpose of the present invention is to display all document components as necessary, or to display only necessary document components within a limited range of documents by limiting the components of the currently targeted document. The object of the present invention is to provide a character processing device that can perform only the following operations. An object of the present invention is to process characters that include a document storage means for storing a document, a sentence designation means for designating an arbitrary sentence, and a sentence display means for displaying only the "sentence" designated by the sentence designation means. The goal is to provide equipment.

5ELSENID is a specified sentence number storage buffer, which stores the sentence number of the sentence selected and specified by the SSE key on the keyboard KB, which will be described later.

j, 5%m, n%d are work variables used as counters, respectively.

The KB is a keyboard that has various function keys such as alphabet keys, character/symbol keys such as hiragana keys and katakana keys, a sentence designation key for specifying a sentence, and a sentence display key for instructing the display of a specified sentence. We are prepared. In the figure, STI is a heading specification key that specifies a heading. SPG is a paragraph specification key that specifies a paragraph. SS
E is a sentence specification key that specifies a sentence. DPG is a paragraph display key that displays a paragraph. DCS is a constituent sentence partial display key that partially displays a constituent sentence within a paragraph. DSE is a sentence display key that displays a specified sentence. .

The DISK is used to store documents that have not been created in a memory for storing standard documents, and the stored documents can be called up when necessary by instructions from the keyboard.

CR is a cursor register. The CPU can read and write the contents of the cursor register. A CRT controller CRTC, which will be described later, displays a cursor at a position on the display device CRT corresponding to the address stored here.

DBUF is display buffer memory. Stores patterns such as document information stored in TBUF.

CRTC is cursor register CR and buffer DBUF
It plays the role of displaying the contents stored in the CRT on the display device CRT.

Further, a CRT is a display device using a cathode ray tube or the like, and the display of a dot configuration pattern and a cursor on the display device CRT is controlled by a CRT controller.

Further, the CG is a character generator that stores patterns of characters and symbols to be displayed on the display unit UCRT.

The microprocessor CPU reads various control signals stored in the ROM, and various controls are performed in accordance with these control signals.

FIG. 2 is a diagram showing an example of a sentence display operation according to the present invention.

In (a), the target document is being displayed, and the upper document component that limits the display range of the "sentence" display, which is the lower document component, is not specified.

In (b), "Sentence J" is being displayed using the constituent sentence partial display key.Since the range of "sentences" to be displayed has not been specified, all "sentences" in the document are displayed. .

(C) shows an arbitrary paragraph of the target document being displayed. In this operation example, the first 15 characters of each paragraph constituent sentence are displayed in an overlapping window over the target document.

In (d), the display of "one sentence constituting paragraph number l among the constituent paragraphs" is specified using the constituent sentence part display key. Currently, an underline cursor is displayed below the statement number so that you can see which statement is specified. Only the "sentences" in the specified paragraph, that is, the sentences that make up the paragraph, are displayed in an overlapping window.

(e) shows the heading of the target document being displayed. Although not shown, 54 in Figure 4
-9, etc., by pressing the heading display key as shown in Figure 2 (
The display of e) may also be performed.

When the paragraph display key is pressed in the display state of (e), the display state of FIG. 2(f) is entered.

This is where the paragraphs that make up heading number 1 are being displayed. In this example, the first 15 sentences of each paragraph are
Characters are displayed in an overlapping window over the target document.

(g), (h), and (i) of FIG. 2 are also diagrams showing examples of sentence display operations according to the present invention.

In (g), a portion of a sentence constituting an arbitrary paragraph of the target document is displayed. In this operation example, the first 15 characters of each constituent sentence are displayed on the target document 9 in an overlapping window.

In (h), sentence number 2 of the constituent sentences is specified using the sentence specification key. Currently, an underline cursor is displayed below the statement number so that you can see which statement is specified.

In (i), the sentence of the sentence number specified by the sentence display key is displayed. Unlike the constituent sentence partial display key, the sentence display key displays the sentence of the designated sentence number without omission in an overlapping window. Note that even in this case, the display of the original document "Japanese Economy" does not change. It is simply displayed as an overlapping window.

Figure 3 shows the document buffer TX in the character processing device of the present invention.
It is a diagram showing the configuration of TBUF. Figure 3(a) is T
FIG. 2 is a diagram showing the overall configuration of XTBUF. TXTBUF
is composed of a document structure frame, a group of heading frames, a group of paragraph frames, and document structure character string data.

(b) is a diagram showing the structure of a document structure frame. The document structure frame is a data frame that manages information on the headings that make up the document, and is composed of a group of pointers to heading frames that store the number of headings in the document and detailed information of each heading.

(C) is a diagram showing the configuration of a heading frame. A heading frame is a data frame that manages information on paragraphs within a heading, including a heading number indicating the unique ID of the heading, a heading start index indicating the starting position of the heading in document structure string data, and constituent paragraphs within the heading. It consists of a group of pointers to paragraph frames that store the number and detailed information of each paragraph.

(d) is a diagram showing the configuration of a paragraph frame. A paragraph frame is a data frame that manages information about the sentences in a paragraph.
A frame is composed of a paragraph number indicating a paragraph-specific ID, a paragraph start index indicating the start position of a paragraph in document structure character string data, the number of constituent sentences in the paragraph, and a group of indexes indicating the start position of each sentence.

(e) is a diagram showing the structure of document structure character string data. The document constituent character string data is a buffer that stores notation character string codes of sentences that constitute a document. For example, it is stored as a JIS code of 2 bytes per character. Parts of the document examples shown in FIG. 2 (g), (h), and (i) are used for explanation purposes.

The operation of the above embodiment will be explained according to the flow.

FIG. 4 is a flowchart showing the operation of the character processing device of the present invention.

54-8 is a process performed when the sentence display key DSE is pressed, and will be described in detail with reference to FIG. Pressing this key causes the second
The display shown in Figure (i) is performed.

54-9 is a process when a key other than the above-mentioned keys on the keyboard KB is pressed, and other than the above-mentioned heading display key,
This process is commonly performed in character processing devices of the same type and is well known, so it will not be described in particular.

54-10 is a display process for displaying the changed portion as a result of the above process. This is a commonly used process in which a single character of data in a document is read, developed into a pattern, and output to a display buffer. It should be noted that the function keys may be used in response to instructions from keys corresponding to display labels on the key screen.

FIG. 5 is a detailed flowchart of the process 54-4. When the paragraph display key DPG is pressed, step 55-1 is a process of checking whether a heading has been specified.

5ELTFRI Check whether D=O,
If it is O, no heading has been specified, so the process branches to 55-9 to display all paragraphs; otherwise, it branches to 55-9 to display only the paragraphs within the specified heading.
Proceed to step 2 (Fig. 3 (b), (, C)).

55-2 is a paragraph display process when a heading is specified, and a heading frame corresponding to the specified heading number is taken out.

55-3 sets the number of paragraphs stored in the specified heading frame to a counter variable n.

Set the initial value 1 to the counter variable i in 55-4, and
-5, it is checked whether all the paragraphs in the heading frame have been displayed by comparing the total number of paragraphs n and i. If i is greater than n, that is, if all paragraphs have been displayed, the process ends. Otherwise, proceed to 55-6.

55-6, the pointer to the paragraph frame (i) stored in the heading frame is followed and the paragraph frame (i) is
) (Fig. 3(d)).

At 55-7, 15 characters of the first sentence in the paragraph frame (i) are displayed in the window. The display on the windows shown in FIGS. 3(d) and 3(e) is a well-known technique that has been widely used in the past, and therefore will not be described in detail. An example of a paragraph display when a heading is specified corresponds to FIG. 2(f).

The counter i is updated by 1 at 55-8 and the process loops to 55-5.

55-9 is a process for displaying all paragraphs in which headings have been specified, and the total number of headings in the document structure frame is set to m (FIG. 3(b)).

At S5-10, a counter variable j is set to 1 as an initial value, and at S5-11 it is checked whether processing has been completed for all headings.

If the counter j becomes larger than the total number m of headlines, it means that the processing has been completed for all the headlines, and the process ends. Otherwise, proceed to S5-12.

At S5-12, the heading frame (j
), and in S5-13 the total number of paragraphs in the heading frame is set in a counter variable n (FIG. 3(C)).

In order to display all paragraphs in the heading in S5-14, set the initial value 1 to counter i, check whether all paragraphs have been displayed in S5-15, and display all paragraphs in the heading. If so, branch to S5-19,
The counter j is updated by 1, and the process loops to 55-11 to process the next heading frame. Otherwise, S
5-16, the pointer to the paragraph frame (i) stored in the heading frame is followed and the paragraph frame (i) is taken out (FIG. 3(C)).

At 35-17, 15 characters of the first sentence in the paragraph frame (i) are displayed in the window (FIGS. 3(d) and (e)).

Displaying on a window is a well-known technique that has been widely used in the past, and therefore will not be described in detail.

In S5-18, the counter i is updated by 1, and the process is repeated in S5-15.

An example of paragraph display when headings are not displayed is shown in Figure 2 (
Corresponds to C). FIG. 6 is a detailed flowchart of the process 54-6. The constituent sentence part display key 56-1 is used to check whether a paragraph has been specified. 5ELPGHI Checks whether D = 0. If 0, no paragraph is specified, so branch to 56-8 to display a portion of the entire text. If not, the sentence in the specified paragraph is displayed. In order to display only a portion of the image, the process advances to 56-2.

56-2 is a sentence part display process when a paragraph is specified, and the paragraph frame corresponding to the specified paragraph number is extracted (FIG. 3(C)).

(d)).

56-3 sets the number of constituent sentences stored in the designated paragraph frame to a counter variable n (FIG. 3(d)).

Set the initial value 1 to the counter variable i in 56-4, and
-5, it is checked whether all the constituent sentences in the paragraph frame have been partially displayed by comparing the total number of constituent sentences n and i.

If i is greater than n, that is, if all constituent sentences have been displayed, the process ends. Otherwise 36-
Proceed to step 6.

At 56-6, 15 characters of the first sentence in the paragraph frame (i) are displayed in the window. The display on the windows shown in FIGS. 3(d) and 3(e) is a well-known technique that has been widely used in the past, and therefore will not be described in detail.

In step 56-7, counter i is updated by 1, and 56-5 returns.

An example of displaying constituent sentence parts when a paragraph is specified corresponds to FIG. 2 (, d).

56-8 is a process for partially displaying all the constituent sentences when a paragraph is specified, and the total number of constituent paragraphs in the heading frame is set to m (FIG. 3(b)).

In step 56-9, the counter variable j is set to l as an initial value, and in step S6-10, it is checked whether processing has been completed for all paragraphs. If the counter j becomes larger than the total number of paragraphs m, it means that the processing has been completed for all paragraphs, and the processing ends. Otherwise, proceed to S6-11.

At S6-11, the paragraph frame (j) in the heading frame is taken out, and at S6-12, the total number of constituent sentences in the paragraph frame is set in a counter variable n (FIG. 3(d)). S
In order to partially display all the constituent sentences in the paragraph in 6-13, an initial value of 1 is set to the counter i, and in S6-14 it is checked whether all the constituent sentences have been displayed, and all the constituent sentences in the paragraph are Once the constituent sentences have been displayed, the process branches to 56-17, where the counter j is updated by 1, and the next paragraph frame is processed at S6-10. Otherwise, the process proceeds to 56-15, and 15 characters of sentence (i) from the beginning are displayed in the window according to the start index of sentence (i) stored in the paragraph frame. Figure 3(d), (
e) Displaying on a window is a well-known technique that has been widely used in the past, so it will not be described in detail.

In S6-16, the counter i is updated by 1 and the process is repeated in S6-14.

An example of displaying part of a constituent sentence when a paragraph is not specified is shown in the second example.
This corresponds to figure (b).

FIG. 7 is a detailed flowchart of the process 54-8.

57-1 sets the specified sentence number in the specified paragraph to d. 57-2 converts the sentence (d) in the specified paragraph frame from the document composition character string data to all the character strings that make up that part, that is, the sentence From the index shown in (d) to the sentence (d
Displays the character code data of one character indicated by the index +1) in a window.

An example of a sentence display when a sentence is specified corresponds to FIG. 2 (+).

[Other Examples] In the above explanation, separate keys were assigned to the keyboard for specifying the sentence to be displayed and for displaying the sentence, and the specified sentence was displayed by the operation after specifying the sentence. It is also possible to designate a sentence and display the sentence in the same operation, so that the sentence can be specified and displayed at the same time. An example in which text specification and text display are performed simultaneously will be described below.

FIG. 8 shows another example of the overall configuration of the present invention.

In the illustrated configuration, the calibration other than KB is completely the same as that in FIG. 1 in the first embodiment, so a detailed explanation will not be provided.

The KB is a keyboard, and includes various function keys such as alphabet keys, character/symbol keys such as hiragana keys and katakana keys, and a sentence specification display key for specifying and displaying sentences.

In the figure, SDT is a heading specification display key for specifying and displaying a heading, SDP is a paragraph specification display key for specifying and displaying a paragraph, and SDS is a sentence specification display key for specifying and displaying a sentence.

The character processing device of the present invention, which is composed of each of these components, operates in response to various human inputs from the keyboard KB, and when an input from the keyboard KB is supplied, an interwoven signal is first sent to the microprocessor CP.
The microprocessor CPU reads various control signals stored in the ROM, and various controls are performed in accordance with these control signals.

FIG. 9 is a diagram showing another example according to the present invention in which a sentence specification and a sentence display operation are performed simultaneously.

(9-1) shows the display of arbitrary paragraph number 10 of the target document. In this operation example, the first 15 characters of each constituent sentence are displayed in an overlapping window over the target document.

At (9-2), sentence number 2 has been selected and specified using the sentence designation display key. As the sentence specification display key, a key that can be freely specified on the display, such as a cursor key during window display, can be assigned. When the specified sentence is displayed, an underline cursor is added and displayed under the specified sentence number, and the sentence with the specified sentence number is displayed in a window.

Although the explanation has been given using a sentence specification display as an example, a constituent sentence partial display operation for specifying and displaying a constituent sentence and a paragraph specification display operation for specifying and displaying a paragraph can be realized in exactly the same way.

The operation of the above embodiment will be explained according to the flow.
