Abstract

PURPOSE:To attain display with the same format as a printing format by displaying an input document while deciding the presence or absence of the execution of hyphenation processing for respective characters inputted in parallel with the input of the document data in the case of displaying words. CONSTITUTION:A key code inputted to an input part 1 is outputted to an MPU 2. The MPU 2 converts the key code into a character code and stores the character code in a sentence memory 4a. Then, the MPU 2 transfers the inputted character code to a display control part 8 to transfer the code to a display part 9. Then, the MPU 2 decides whether the final word in a row inputted at present is divided on the way or not. If the word is divided on the way, the MPU 2 accesses a hyphen position retrieving part 3b in a ROM 3 to retrieve the hyphen position, and if a hyphen an be inserted, inserts the hyphen into the position concerned and displays the hyphened character string on a display part 9. Consequently, the operator can input a sentence without considering the hyphen position inserting processing during its input and the sentence having the same format as the displayed on can be printed out from a printing part 6.

Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a document processing bag that displays and prints input character information, and particularly relates to a document processing bag that displays and prints input character information, and in particular, performs hyphenation processing on input character information and prints it. The present invention relates to a possible document processing device.

[Conventional technology]

Conventionally, document processing devices such as electronic typewriters have rapidly become multi-functional so that they can memorize input documents, edit them in a variety of ways, and print them. It is configured so that it can be done.

By the way, in this type of device, the operator usually edits the document while referring to the document information displayed on the display, but recently the display that displays 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 human 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 uniform printing, resulting in an inferior quality printed document.

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

However, since the input document is displayed without any consideration of the automatic hyphenation process described above, the operator who manually inputs the document will obtain a printed document that differs from the human document display format, resulting in an unintended print format. Therefore, there were problems with operability, such as the inability to faithfully reflect the intentions of the operator who entered the document. Further, as a conventional branch display processing form, there is one shown in FIGS. 5(a) and 5(b).

FIGS. 5(a) and 5(b) are diagrams for explaining the conventional document input display state, where L indicates a left margin and R indicates a right margin.

Figure (a) shows a document manual status screen using the left margin forced hyphen display method. When each character of an input word falls within the right margin R, keyboard input is set to a locked state and hyphenation processing by the operator is disabled. This is the type that releases the keyboard lock state after inserting a hyphen, and the hyphen is automatically inserted without taking into account the word breaks in the right margin R, resulting in a document that is extremely difficult to read. .

Figure (b) shows a document input status screen using the word wrap method.
When the number of characters in a word increases, for example, when the number of characters in one word is large, such as German In this case, word wrapping occurs in the vicinity of the write margin R, resulting in non-uniform display and printing.

This invention was made in order to solve the above-mentioned problems, and it displays a manual document while determining whether or not to perform hyphenation processing for each character that is input in parallel with the input of document data. It is an object of the present invention to provide a document processing device that can perform hyphenation processing and display of a document in the same manner as the printed form.

[Means for solving problems]

The document processing device according to the present invention includes a display device that displays document information to be input, and an end-of-line device that monitors the document input occurrence state related to the end of a line on the display device sequentially for each character during document input and detects the end-of-line character. At the end of the manual input of a word whose factor is the character detected by the input detection means and the line end manual detection means, the hyphen insertion position information stored in the hyphen insertion information storage means is referred to, and the word at the end of the line on the display is and a hyphen display control means for inserting a hyphen character and displaying it separately over two lines.

[Effect]

In this invention, the end-of-line input detection means sequentially monitors the occurrence state of document input at the end of a line on the display for each character during document input, and when a character at the end of a line is detected, a word whose factor is this character is detected. At the end of the manual input, a hyphen display control means refers to the hyphen insertion position information stored in the hyphen insertion information storage means, inserts a hyphen character into the word at the end of the line on the display, and displays the word separately over two lines.

〔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 input unit 1 may be, for example, data transmitted from a storage device such as a floppy disk or a communication device. 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 manually from the input unit 1. Reference numeral 5 denotes a printing control section which reads out a character code string to be printed and printing control data from the MPU 2 and controls printing by the printing section 6. A print buffer 7 temporarily stores print information printed by the print unit 6. 8 is a display control unit which also serves as a hyphen display control means of the present invention;
The display information stored in the display buffer 10 is displayed on the display section 9. The MPU 2 also serves as the end-of-line human power detection means of the present invention, and monitors the state of document manual effort at the end of a line on the display section 9 for each character while inputting a document, and when a character at the end of a line is detected. At the end of inputting a word with this character as a factor, the display control unit 8 refers to the hyphen insertion position information stored in the hyphen position storage unit 3b, and
A hyphen character is inserted into the word detected by the PU 2 at the end of the line on the display section 9, and the word is displayed separately over two lines. Note that the present invention is applicable even when the display capacity of the display section 9 is only one line.

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

FIG. 2 shows a text display transition diagram on the display section 9 shown in FIG. 1, and the same parts as in FIG. 5 are given the same reference numerals.

In this figure, L1 to L indicate the display transition in the same line, for example, a state where the word 'prevaIled' is being input, and M indicates the display state of the next line.

FIG. 3 is a flowchart illustrating the display control operation procedure according to the present invention. Note that (1) to (12) indicate each step. Also, each step (1) to (12) is the first
It is stored in the control program 3a shown in the figure.

When the power is turned on, this flow starts, and it is determined whether a key code has been input from the human power section 1. If a key code has been input, the MPU 2 converts the key code into a character code and stores it in the text memory 4a. (1). Next, the MPU 2 displays the manually entered character code in the display control unit 8.
Transfer to.

In response to this, the display control unit 8 stores the character code in the display buffer 1o, and displays the manually entered character on the display unit 9 (2). Next, the MPU 2 determines whether the line being input exceeds the right limit, that is, the right margin, due to the character code input in step 3), and if No, returns to step (1); YES
If so, convert the key code currently being input into a character code and accept the same character input as in step (1) above (4
), and checks whether the input character code is a word delimiter (5). Character codes that do not separate words include alphabets, numbers, periods, hyphens, apostrophes, etc. of each language.If any other character code is input, it will be treated as a word separation and will not be processed in the following steps. I do.

Next, it is determined whether the input character code is a word delimiter 6), and if No, the display control unit 8 displays the input character code on the display unit 9 (step 7). Return to (4). That is, the second
The display transition shown in the figure from step (1) to L3 is
Processing is performed in accordance with step (3), and display transitions 4 to L7 are processed in steps (4) to (7).

On the other hand, in the case of YES in step (6), the MPU 2 accesses the hyphen position storage section 3b of the ROM 3 and searches for the hyphen position in order to insert a hyphen "-" at the appropriate position of the input word. (8). Note that information on appropriate hyphen positions corresponding to various words is stored in the hyphen position storage unit 3b in the form of a bitmap of 1 bit per position, and it is possible to search by the type of character code that constitutes the word. It has become. However, 1. If the searched word is a proper noun or the like and the hyphen position information is not stored in the hyphen position storage section 3b, a bitmap is obtained indicating that insertion of a hyphen is not possible. For this reason,
As shown in FIG. 2, in the display transition L7, when the word delimiter "," is entered manually, step (8
), search for the hyphen position of the word 'prevai led', and use 'rpreJ' and 'rvailect'.
The MPU 2 recognizes this and moves on to the processing from step (9) onwards.

The searched hyphen position is then in a valid location and
Also, determine whether the hyphen position is located to the left of the right margin R9), and if YES, insert a hyphen at the relevant location and set that position as the last character of the line in a pointer that will be a variable 10) , step (12
) and if NO, set the pointer to the left delimiter of the tested word as the last character of the line (11)
. Next, the MPU executes an instruction to execute a line feed by referring to the value of the pointer set in steps (10) and (11).
2 to the display control section 8. In response to this, the display control unit 8
Now, let's control the display section 9 to display a line break (12).
The line feed information there is stored in the display buffer 10. This corresponds to display transition 8 and display state M of the next row shown in FIG.

Thereby, the operator can input text without considering the hyphen position insertion process during input, and the same text as the displayed document format can be obtained from the printing unit 6.

Therefore, as shown in FIG.
The input document can be displayed on the display section 9 with the input document inserted at an appropriate position in each character of the word on the light margin R, based on the position of It will be printed from the printing section 6.

Note that in the above embodiment, a case was explained in which document data created by a document processing device that has an automatic hyphenation function is processed, but document data created by a document processing device that does not have an automatic hyphenation function is stored in the text memory. 4a, it is displayed line by line on the display section 9, and when the operator recognizes that there is a considerable amount of blank space near the light margin R of the document displayed on the display section 9 (depending on the individual operator), occurs),
If you move the cursor to the beginning of the next line and enter a command to specify hyphenation, you can display the word that was placed at the beginning of the next line with the above hyphenation applied.

In addition, if the display form of the hyphenated word at the end of each line does not occur at the position intended by the operator as described above, the MPU 2 changes the word in response to the operator's request to select the hyphen position. By sequentially moving hyphens between constituent characters so that the operator can select them, hyphenation processing can be executed at a desired position requested by the operator.

〔Effect of the invention〕

As explained above, the present invention includes a display device that displays input document information, and a document input occurrence state related to the end of a line on this display device, which is sequentially monitored for each character during document input to detect the end of line character. End-of-line input detection means refers to the hyphen insertion position information stored in the hyphen insertion information storage means at the end of inputting a word whose factor is the character detected by the end-of-line input detection means, and detects the end of the line on the display. Since a hyphen display control means is provided that inserts a hyphen character and displays the word separately over two lines, the word at the end of the line on the display can be displayed in a form that conforms to the printing format in parallel with the sequential manual input of the document. Hyphenation can be displayed 1. Desired documents can be input efficiently and continuously without the operator having to display hyphenation at the end of a line. In addition, the input document can be printed in the same format as the display format, and the display format and print format are always the same. This has the excellent effect of outputting documents in a consistent state.
