Abstract

PURPOSE:To attain a display hyphened with the same format as a printing format by deciding the divided state of a word expressed by using characters arrayed on two rows as factors in the case of displaying words and displaying read storage document by using a hyphen. CONSTITUTION:A key code inputted to an input part 1 is outputted to an MPU 2. The MPU 2 scans character data by one row, and if the final character of the row is on the way of a word, reads out a bit of hyphen position information by referring a hyphen position storing part 3b. The MPU 2 decides whether a hyphen can be inserted or not, and when it is possible, inserts a hyphen character into the position concerned and transfers a character string from the row head of a display part up to the hyphen character to a display buffer 7 through a display control part 5. The character string stored in in the buffer 7 is displayed on a display part 6 and the succeeding row also is similarly processed by expressing the head of undisplayed data as the character next to the hyphen. Consequently, display with the same format as printing format can be attained.

Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a document processing device that displays and prints input character information, and in particular, is capable of performing hyphenation processing on input character information and printing. The present invention relates to a document processing device.

(Prior Art) Conventionally, document processing devices such as electronic typewriters have rapidly become multi-functional so that they can store input documents, edit them in various ways, and print them. It is configured to enable high-quality printing.

By the way, in this type of device, it is customary for the operator to edit the document while referring to the document information displayed on the display, but recently the display that displays the input document information has become larger. , devices that can display input documents in a format similar to printed format have also been developed.

However, if the input document is based on a foreign language, such as one composed of 26 alphabetic characters, language-specific word wrapping is required. In other words, if a word consisting of a series of characters is entered beyond the set light margin, a control is executed to automatically advance the word that falls within the light margin to the next line. .

[Problem to be solved by the invention] However, when an input word with a large number of characters spans the light margin, word wrapping occurs frequently and the word printing form near the light margin becomes very irregular. This results in uniformity, resulting in an inferior quality printed document.

Therefore, the delimiter information of manually entered documents, that is, hyphen insertion information, is stored in advance, and when printing is performed by specifying batch printing of manually entered document information, the automatic hyphenation process that inserts the hyphens and prints can be executed. A model is being developed.

However, since the automatic hyphenation processing described above is not taken into account when displaying manually-generated documents, the operator who inputs the document will receive a printed document that differs from the human-generated document display format, resulting in unintended printing formats. Therefore, there were problems with operability, such as the inability to faithfully reflect the intentions of the operator who entered the document.

This invention was made to solve the above problems, and reads the stored document information in units of the maximum number of characters that can be displayed on the display when a request to display document data is generated, and uses the characters at the end of the line as a factor. To obtain a document processing device capable of displaying a stored document on a display device in the same hyphenated form as the printed form by determining the splitting state of the word to be read and displaying the read stored document as a hyphen. The purpose is to

[Means for Solving the Problems] The document processing device according to the present invention processes words whose factor is the end-of-line character in document information read out from the document storage means in units of the maximum number of characters that can be displayed on one line of the display. A division type determination means for determining the division type, and hyphen insertion position information stored in the hyphen insertion information storage means based on the word division type of the line-end character determined by the division type determination means, and the end-of-line character on the display and display control means for displaying the word at the beginning of the next line as a hyphen.

[Effect]

In this invention, when a document display request is made,
The division form determining means determines the division form of a word with the end-of-line character as a factor in the document information read out from the document storage means in units of the maximum number of characters that can be displayed on one line of the display, and based on the end-of-line character-word division form. The display control means refers to the hyphen insertion position information of the word stored in the hyphen insertion information storage means, and displays the words at the end of the line and the beginning of the next line on the display as hyphens.

〔Example〕

FIG. 1 is a block diagram illustrating the configuration of a document processing apparatus showing an embodiment of the present invention. Reference numeral 1 denotes an input unit composed of, for example, a keyboard, and includes character keys.

By pressing a symbol key, the key code data corresponding to the pressed key is sent to the MPU 2 of the microprocessor, etc.
Output to. Note that the human power section 1 may be transmitted data from a storage device such as a floppy disk and a communication device, for example. Reference numeral 3 denotes a ROM, which includes a control program 3a for the MPU 2, a hyphen position storage section 3b for storing hyphen insertion position information for each word consisting of a collection of character code information, and the like. Reference numeral 4 denotes a RAM, which functions as a work memory for the MPU 2 and has a text memory 4a that temporarily stores character code strings etc. converted from key codes input from the input section 1. Reference numeral 5 denotes a display control section which also serves as a hyphen display control means of the present invention, and causes the display section 6 to display the display information stored in the display buffer 7. In addition, MPU2
also serves as the division form determining means of the present invention, and determines the division form of words using the end-of-line character as a factor in the document information read out from the text memory 4a in units of the maximum number of characters that can be displayed in one line on the display section 6. , the display control section 5 serving as a display control section refers to the hyphen insertion position information stored in the hyphen insertion information storage means based on the word division form of the end-of-line character, and displays the words at the end of the line and the beginning of the next line on the display section 6. Display a hyphen. 8 is a printing section, which is a text memory 4 by MPU2.
The document information read from a is printed based on predetermined print control information.

Next, the hyphen display control operation according to the present invention will be explained with reference to FIGS. 2 and 3.

FIG. 2 is a schematic diagram illustrating the document display format displayed on the display section 6 shown in FIG. 1, where 11 shows a document display screen using the word wrap method, and 12 shows a hyphen display screen. Note that L indicates the left margin of the display section 6, which is the left limit of the line. R indicates the right margin of the display section 6, which is the right limit of the row. Note that the present invention is applicable even when the display capacity of the display section 6 is only one line.

FIG. 3 is a flowchart illustrating the hyphen display control operation of document information according to the present invention.

Note that (1) to (13) indicate each step. In a document processing device such as an electronic typewriter, when the power is turned on, the document display screen 11 shown in FIG. An example will be explained in which the display format is changed to the hyphen display format.

When a command key for prompting the execution of hyphenation display is input from the input unit 1, this flow starts, and various variables are initialized (1), and at this time, the distance between the left and right merges is checked. Next, the MPU 2 reads a character string with a length corresponding to the distance between the left and right margins from the text memory 4a, scans one line of character data in the text 2), and reads the last character of the line, that is, the right margin R. In this example, the word r p
"a", which is a word factor of "revailed J", corresponds to this. Next, the word factor r B applied to the light margin R
Determine whether J is in the middle of the word rprevailed J (determine the split form of the word with the end-of-line character as a factor) L, (3), If YES, that is, the word r
If prevailed J is displayed over this line and the next line (split display), the MPU 2 checks the word that includes the last character of the line (a word whose factor is the last character of the line) (4
). The definition of a word is a string of characters sandwiched between word delimiters, consisting of characters other than the blank code and command code that separate the words.

Therefore, after further removing characters such as symbols and numbers from this word, the MPU 2 refers to the hyphen position storage section 3b from the character string forming the word and reads out the hyphen position information. In the hyphen position storage unit 3b, appropriate hyphen position information corresponding to various words is stored in the form of a 1-bit bitmap for each position, and it is possible to search by the type of character code that constitutes the word. ing. If the searched word is a proper noun or the like and hyphen position information is not stored in the hyphen position storage section 3b, a bitmap in which hyphens cannot be inserted is obtained.

Next, as a result of the search in step (5), it is determined whether or not there is a position where a hyphen can be inserted in the checked word, and the position where a hyphen can be inserted is the right margin R.
If the hyphen is located on the left side of the word, in other words, whether the hyphen position is in a valid position 6), then the character string up to the blank before the word is transferred to the display buffer 7), step (11). ) (same as the conventional word wrap display), and if YES, in this example, the word r
prevailed J's rp 1” eJ and rva
The hyphen insertion position is between ``iled'' and the hyphen insertion position is on the left side of the word factor raJ on the right margin R, so the word r prevailed
Please insert a hyphen character "-" in the corresponding position of J8),
The character string from the beginning of the line to the hyphen character on the display section 6, that is, r However...pre-J is displayed on the display control section 5.
(9).

On the other hand, if the judgment in step (3) is NO, that is, if the area on the right margin R is a word break or the end of a word, in this embodiment, the first word in the fifth line from the top of the text display screen 11 If the word factor "n" of "rplebeian" is applicable, and in this case, one line of character string r
tion-.plebeian" to the display buffer 7 via the display control unit 5 (lO).

Next, the character string stored in the display buffer 7 is displayed on the display section 6.
For example, as shown in the hyphen display screen 12 of FIG. 2, the word factor "pr
A hyphen character "-" is inserted and displayed on the corresponding line in "e" (11). Next, set the variable (pointer) that points to the beginning of the undisplayed data to the characters of the word rprevailed J.
12), determine whether there is undisplayed data 13), and if YES, return to step (2).
If No, the hyphen display control ends.

By controlling the display in at least three forms in this way, the hyphen display screen 12 is displayed on the display unit 6 as shown in FIG. The input document information can be displayed in the same format as the hyphen batch printing format by the printing unit 8.

Note that if the operator makes corrections, changes, or additions to a document that has been automatically or manually hyphenated, the format of the input document after the change position will be corrupted, so if the input document information is corrected or edited, It goes without saying that if the hyphenation process that has already been performed is invalidated or the new hyphenation process is automatically executed based on the hyphenation process, manual and editing of the document can be performed more efficiently.

Also, if you change the format of document information such as margins or indentation that has already been input, the hyphenation processing that has already been done will become meaningless, so the hyphenation shown in Figure 3 will be displayed based on the status of the format change. If the system is configured to execute the control, the operator can continue editing the document without being aware of the occurrence of word breaks at the end of the line, and can print the document in the intended document display format.

〔Effect of the invention〕

As explained above, the present invention includes a division form determining means for determining the division form of a word using the end-of-line character as a factor in document information read out from the document storage means in units of the maximum number of characters that can be displayed in one line on a display. , refers to the hyphen insertion position information stored in the hyphen insertion information storage means based on the word division form of the end-of-line character determined by this division form determining means, and displays the words at the end of the line and the beginning of the next line on the display as hyphens. Since the display control means is provided, when displaying input document information, if human words are divided by the set light margin, the input document can be displayed in the same manner as the hyphen character insertion printing format. , it has the excellent advantage of being able to print out the same document information as in the display format, and also allowing documents to be input continuously without having to worry about the troublesome process of inputting hyphens at the end of lines, greatly improving document input efficiency.
