Abstract

PURPOSE:To adjust a character width at the time of printing while an original document is preserved, by mounting a collation means for collating document data and a table, a memory means for storing the document data in the display width indicated by the table and a display means of a document. CONSTITUTION:The character code is read from a main memory part 6 in the order of characters inputted to an original document memory region 6A. Each character code is sent to a pattern collation part 5 from a pattern memory part 4 to discriminate whether said character code corresponds to a pattern objective character. As a result, when said one character is not the pattern objective character, the character width information thereof and the character code are stored in a display document memory region 6B. When said character is the pattern objective character, the next one character is read from the original document memory region 6A and, when said character corresponds to a two-character pattern, a two-character pattern conversion table is read from the pattern memory part 4 to be written in the display document memory region 6B. When said character does not correspond to the two-character pattern, it is discriminated whether said character is a three-character pattern and, when said character does not correspond thereto, a signal showing that pattern matching does not come into existence is outputted and the character width of the first one character is decided as an 'em' size.

Description

Detailed Description of the Invention 3. Detailed Description of the Invention "Field of Industrial Application" The present invention relates to a document processing device that can electronically create, edit, print, etc. a document using a word processor or the like.

``Prior art'' When Nihon Go's documents are printed by typesetting, the spaces between certain symbols, punctuation marks, parentheses, emphasis marks, return marks for kanji characters, etc. are appropriately shortened. It's easy to read, looks natural, and is easy to read.

"Problem to be Solved by the Invention" However, when creating a document using an ordinary word processor, it is necessary to specify the width of characters or symbols (hereinafter simply referred to as characters) to be changed as appropriate at these punctuation points. There must be. For example, if you take a right parenthesis “(”, a normal word processor will handle it in a full-width font “(”).
and half-width font "("), and it was necessary for the operator to select these fonts at his/her will. Therefore, with conventional document processing devices, it is difficult for people with no knowledge of printing punctuation to limit the character width. There is a problem in that it is difficult to create beautiful printed matter with adjusted character widths, and switching the character width is difficult even for experienced users.

For this reason, devices are being considered that create documents in which character widths are automatically adjusted for predetermined combinations of characters according to typesetting rules. However, with such automated devices, if characters are added or deleted from part of the converted document, the characters that meet the prepress rules may no longer match, and in this case, the character width must be restored to the original width. The problem was that I couldn't do it.

SUMMARY OF THE INVENTION Accordingly, an object of the present invention is to provide a document processing device that can adjust the character width during printing while preserving the original document.

``Means for Solving Problems with Problems'' The present invention provides document editing means for electronically editing a document, and a means for changing a predetermined combination of characters or symbols. a table indicating the desired width; a document data storage means for storing document data created by the document editing means; a collation means for collating the document data with the table; For characters or symbols that match, these document data are temporarily stored in the display width that has already been set, and for characters or symbols that match the combination, these document data are temporarily stored in the display width specified in the table. A document processing apparatus is provided with display data temporary storage means for storing data, and display means for displaying a document based on the data stored in the display data temporary storage means or the document data storage means. Here, the display means may be a printing means for printing a document, or may be a CRT, a liquid crystal display device, etc. for displaying a document on a screen.

According to the present invention, data after the character width has been changed is stored in the display data temporary storage means and used as temporary display data. Therefore, the original document exists, and it is possible to make changes to it and adjust the character width again.

"Example" The present invention will be described in detail with reference to Examples below.

FIG. 1 shows the configuration of a document processing device according to an embodiment of the present invention. A document processing section 1 of this document processing device includes a CPU (central processing unit) 2. CPU
2 is connected to various parts within the processing section through a bus 3, and is also connected to other devices through an interface circuit (not shown).

The document processing section 1 is provided with a pattern storage section 4 that stores patterns for character width conversion, and a pattern matching B5 that matches the patterns with character codes. The document whose character width is to be changed is stored in the original document storage area 6A of the document storage section 6, and the display document whose character width has been changed is stored in the display document storage area 6B. Display memory 8
is a memory for storing display data for one page.

Outside the character processing unit 1, there are a disk memory 11 that stores procedures for controlling this document processing device, a printer 12 for outputting documents, a display 13,
Also connected are a keyboard 14 and a floppy disk 15 for performing input operations such as creating documents. Further, a communication device 16 is connected to this document processing device,
Through this, a document can be output to another printer I7, and the file service means 18 can read and write the document.

Now, assume that an operator uses the keyboard of this document processing device to manually edit a certain document.

In this case, each input character is sequentially stored in the original document storage area 11ff16A of the main storage section, and displayed in full-width characters on the display 13.

Assume that after the document has been created in this manner, the operator instructs the display 13 to display this document in a character width that conforms to the prepress rules.

FIGS. 2 to 4 show character widths in accordance with this plate-making rule. Here, Figures 2 and 3 show the case where the character width is restricted between two adjacent characters (two-character pattern), and Figure 4 shows the case where the character width is restricted between three consecutive characters. Indicates the case (3 character pattern). In these figures, "double" refers to characters that are half-width (character width is half the normal width (full-width)), and "quarter" refers to characters that are half the width of half-width characters.

In this embodiment, in order to realize such conversion to character width, the pattern matching section 5 is provided with a pattern target character list as shown in FIG.

In FIG. 5, the right column shows the types of characters whose character widths may be changed, and the bottom column shows blanks. In addition, the right column in the figure shows patterns classified into four groups.

The operation of changing the character width using this pattern target character list will be explained in conjunction with the following FIG. 6.

When the operator instructs to display a document with a character width that conforms to the prepress rules, the character codes for the document are read out from the main memory 6 in the order of the characters input into the original document storage area 6A (step ①). ). This read character code for one character is stored in the pattern matching section 5. The character codes of the target characters constituting the pattern target character list are sent from the pattern storage unit 4 to the pattern matching unit 5 (step ■), and it is determined whether the character is a pattern target character or not (step ■).

As a result, if that one character is not a pattern target character, a signal indicating that pattern matching is not established is output (step ■).In this case, the character width information and character code are used without changing the character width (full-width). is stored in the display document storage area 6B (step (2)).

On the other hand, if the character is determined to be a pattern target character, the next character is read out from the original document storage area 6A (step (2)). For this one-character character code, the pattern matching unit 5 completes the pattern target character list shown in FIG. 5 in the same manner as described above (step 2). Then classify this character in the same way,
It is determined whether the two characters form a two-character pattern (step ■). If the first character and the next character correspond to any of the classification combinations shown in Figure 7, they correspond to a two-character pattern. For example, if there are two consecutive right angle brackets "", the classification is "1" for both characters, and the seventh
This corresponds to the first combination in the diagram.

If it corresponds to a two-character pattern, the pattern storage unit 4
The two-character pattern conversion table shown in the right half of FIG. 7 is read from (step 2).

In this case, a pattern matching establishment signal is output (step ■), and these character codes are written into the display document storage area 6B together with character width information (step ■).
.

On the other hand, if the two-character pattern is not found in step (2), it is determined whether those two characters are a combination of three-character patterns (step (2)). There is only one combination of three-character patterns as shown in FIG. Therefore, of the two character classifications found, the third classification will be considered only when the first classification is "2" and the second classification is '4''.3. If it is found that the character pattern does not match, a signal indicating that pattern matching is not established is issued, and in this case, the character width of the first character is determined to be full-width (step ■).

On the other hand, if the two characters correspond to part of a three-character pattern, the next character code is read from the original document storage area 6A (step ○), and it is determined whether the two characters are part of a three-character pattern. is carried out (step 9). As a result,
For example, if these three characters correspond to a three-character pattern such as ") (°,"
The three-character pattern conversion table shown on the right side of the figure is read out (step ■). Then, a pattern matching establishment signal is output (step 0), and these character codes are written into the display document storage area 6B together with character width information (step 2).

The above operations are repeated character by character until processing for one document is completed. During this conversion process, the display document storage area 6
When the data written in B corresponds to one line (step @), the contents are sent to the display memory 8, and the contents are displayed on the display 13 (step 0).

On the other hand, if the operator requests printing with the character width changed, all the converted data of the document is stored in the display document storage area 6B, and this is read out and sent to the printer 12. is printed. When the operator instructs remote printing, the communication device 16 sends the document data to the target printer 17.
The image will be sent to , where it will be printed.

FIG. 9 shows the structure of print information when printing is performed by controlling the character width with the printer of this embodiment. In this way, when printing a document, a document start flag indicating the start is sent. Next, the character width information specifies the character width to be printed and the start and end positions of the characters to which the character width is applied, followed by a character code string of the corresponding character width. If there is a change in character width, information on the character width is sent immediately before the character code to be changed, and then the code for the corresponding character is sent.

The following FIG. 10 shows the relationship between character data and print information for a part of a document. In this example, the first to 22nd characters are instructed to be printed in full-width characters, and the 23rd parenthesis ")" is instructed to be printed in half-width characters. From the 24th onwards, full-width printing will be performed again.

In the embodiment described above, the operator operated the keyboard to create the document, but the floppy disk 15
Of course, it is also possible to transfer the document from another device using the communication device 16, store it in the original document storage area 6A, and change the character width.

Further, in the embodiment, the program for controlling the character width is stored in the disk memory, but it can also be stored in a storage medium other than this. It goes without saying that the disk memory 11 can not only simply store programs, but also serve as various storage units such as the document storage unit 6 of the document processing unit l.

"Effects of the Invention" As explained above, according to the present invention, even if a document is changed, punctuations can be processed reliably and quickly. Moreover, since the document whose character width has been changed is only temporarily stored for display, the same document does not exist twice, and its management is easy.
