Description

DETAILED DESCRIPTION OF THE INVENTION (a) Field of Industrial Application The present invention relates to a mixed European and Japanese text processing device that is capable of processing texts in which both European and Japanese texts are mixed in block units.

(b) Prior art At present, word processors that can process only Japanese text and word processors that can only process European text are becoming widely available, but devices that can process texts that contain a mixture of European and Japanese texts have not yet been put into practical use. I haven't reached it yet.

The reason for this is that the processing formats for European and Japanese texts are completely different. That is, while Japanese text processing requires a kana-kanji conversion function and a character-by-character deletion/insertion function, European language processing requires an auto-carrier return function and a word-by-word deletion/insertion function.

Currently, methods for processing mixed European and Japanese texts that have been proposed include (i) a method of specifying the processing of European and Japanese texts on a block-by-block basis, (ii) a method of specifying processing of European and Japanese texts on a line-by-line basis, and (iii) a method of specifying the processing of European and Japanese texts on a line-by-line basis. There are three methods: one is to specify the processing of European and Japanese sentences from any position in the file.

With the methods (i) and (ii) above, it is not possible to include European and Japanese mixed sentences in the same block or in the same line, resulting in extremely poor operability when creating documents.

An example of specifying the processing of European and Japanese text using method (iii) above is shown in FIG. In the figure, ““” are the left and right margins that define one line of text, and “◇”
is an indent mark to divide a line into blocks. In addition, "□E" and "□J" in the figure designate that the text after these marks is a European language or a Japanese language.

In word processors that are currently widely used (for example, SWP-3000 manufactured by Sanyo Electric Co., Ltd.), when blocks in adjacent lines match, they are processed as the same block. That is, the text shown in FIG. 1 is divided into four block areas 1 to 4, as shown by dotted lines in the figure.

Therefore, in the third and fourth block areas 3 and 4, the "□J" mark and the "□E" mark specified at the beginning of each block specify that the text in the block is Japanese or European, respectively. Also, the first
In block area 1, there is a "□E" mark at the beginning of the first line and a "□J" mark in the middle of the second line, so the text from the first line to the middle of the second line is defined as Roman. The text from the middle of the second line to the third line is defined as Japanese text. Furthermore, in the second block area 2, there is a "□E" mark at the beginning of the first line and the middle of the third line, and a "□J" mark at the beginning of the second line.
The sentences from the middle of the first line and the third line to the fourth line are defined as European texts, and the sentences from the beginning of the second line to the middle of the third line are defined as Japanese texts.

If method (iii) above is adopted in this way, it is possible to provide mixed European and Japanese sentences even in the same block or line.

However, a problem arises when such text is processed line by line, such as in print processing. That is, the first
When you print a line and then try to process the second line, you do not know which mode to use to process it because there is no European language standard mark at the beginning of the first block area 1 in the second line. A problem arises.

(c) Purpose of the Invention The present invention has been made in view of the above points, and provides a mixed European and Japanese text processing that is optimal for processing a sentence containing a mixture of European and Japanese texts and consisting of a plurality of blocks line by line. The aim is to provide the equipment.

(d) Structure of the invention FIG. 2 shows a schematic structure of the device of the present invention, in which 1 is a text means in which ready-made European and Japanese mixed sentences are stored;
2 is a first information means in which block information of the next line to be processed is stored; 3 is a second information means in which block information of the line immediately before the line to be processed and position information of the European text are stored; 4 is a comparison means for comparing the block information of the first and second information means 2 and 3;
Denoted by numeral 6 is a confirmation information means in which position information of the European and Japanese text of the above-mentioned processing line is stored, and 6 is a control means for controlling each of the above-mentioned means.

In such an apparatus, the control means 6 searches the text means 1 for the block position of the next line to be processed, stores it in the first information means 2 as block information, and also searches for the block position of the next line to be processed. The comparing means 4 compares the block information of the line immediately before the above-mentioned processing line and the block information stored in the first information means 2, and for the matched block, the block information stored in the first information means 2 is compared with the block information stored in the first information means 2. 3, it is determined whether the first character of each block of the processing line is a European character or a Japanese character, based on the positional information of the European character stored in advance in the step 3, and the determination result is stored in the determining means 5. Features.

(E) Embodiment FIG. 3 shows an embodiment of the present invention, in which 11 is a control section consisting of, for example, a microcomputer;
The control section controls each section described below using control signals _C1 to _C6 .

12 is, for example, RAM (random access memory)
This is a text memory consisting of a text memory containing European and European mixed sentences that have already been created.

13 is a line reading unit, and the line reading unit is connected to the control unit 1.
Based on the control signal C1 from 1, one line of data is read from the text memory 12 and stored in the line buffer 14. Specifically, the signal C1 includes a read instruction signal from the text memory 12 and a line designation signal that designates the line to be read. Further, such a row designation signal is determined by the value of a row counter provided in the control section 11.

Reference numeral 15 denotes a block search unit, which searches a line of data stored in the line buffer 14 based on the control signal C2 to determine how many characters from the beginning of each block in the line. Information starting from the number of characters is written into the first information section 16. Specifically, suppose that one row of data as shown in FIG. 4A is stored in the row buffer 14,
If the left margin position is the 0th character, the information searched by the search section 15 and written into the first information section 16 will be as shown in FIG. 4B. 17 is the second
This is an information section, and the information section stores information on each block of the line immediately before the line currently being processed and information as to whether the last character of each block has been processed in Latin or Japanese. Specifically, if the line just before the above is as shown in Figure 4C, then the second line
Information is stored in the information section as shown in FIG. 4D. That is, since the last character of the first block area in the immediately preceding line is a Roman character, and the last character of the second block area is a Japanese character, the final character information section of the second information section contains "European" and "Japanese", respectively. The information is stored.

18 is a comparison section, and the comparison section receives the control signal C3.
The block information in the first and second information sections 16 and 17 is read out based on the information and compared. If a matching block is found as a result, the block information is sent to the European determining section 19.

Based on the control signal C4, the European/Japanese determining section 19 determines from the contents of the line buffer 14 and the comparing section 18 whether to perform European processing or Japanese processing on each character in the line to be currently processed. A decision is made based on the sent information and the information is written into the final information section 20.

Specifically, assume that the line to be processed now is the line shown in FIG. 4A, and the line immediately preceding this line is the line shown in FIG. 4C. At this time, as is clear from FIGS. 4B and 4D, the first blocks of the processed line and the previous line match. Therefore, the first
The content of the final character information at the first block position in the second information section 17, that is, "Europe" in this case, is stored in the portion corresponding to the character position (FIG. 4E). Next, the line buffer 14 is searched, and the margin, indent, and European text information in the buffer is read out and written into the corresponding definite information section 20 (FIG. 4F).

21 is a print control section, and the control section receives control signals.
According to C5, one row of data stored in the row buffer 14 is output based on the information stored in the final information section 20. Specifically, since "Europe" is stored in the first and ninth character positions of the confirmed information section 20, and "Japanese" is stored in the third and sixth character positions, the The characters in the 2nd, 10th, and 11th character positions are printed as Roman characters, and the characters in the 4th, 7th, and 7th character positions are printed as Japanese characters.

Reference numeral 22 denotes a block data creation section, which searches the confirmed information section 20 based on the control signal C6, reads out each block information in this information section and the final character information of each such block, and stores it in the second information section. 17
Store in.

Next, the operation of the apparatus of this embodiment will be explained using the flowchart of FIG. 5 and the schematic diagram of FIG. 6.

Now, as shown in FIG. 6A, it is assumed that a sentence consisting of three lines is stored in the text memory 12, the first line has already been processed, and the second line is about to be processed. . At this time, the second information section 17
Information as shown in FIG. 6B is stored in the .
The operation in such a state will be explained below based on the flowchart of FIG.

First, in step S1, the second line is transferred from the text memory 12 to line buffer 1 based on the control signal C1.
Read out to 4. Next, in step S2, block information in one row of data in the row buffer 14 is searched. Specifically, the block search unit 15 searches the row buffer 14 based on the control signal C2, and the search result is stored in the first information unit 16. The information stored in the first information section 16 is shown in FIG.
The result will be as shown below. Processing then proceeds to step S3.

In the S3 step, the first and second information sections 16 and 17
Search and see if a matching block exists. Specifically, the comparison section 18 reads and compares the information stored in the first and second information sections 16 and 17 based on the control signal C3.

In such a comparison, if a matching block exists, the process proceeds to step S7 via steps S4, S5, and S6, and if no matching block exists, the process proceeds to step S7 via steps S4, S6.

The processing of steps S4, S5, and S6 is performed in the European determining section 19 based on the control signal C4. Specifically, in step S4, the comparison results sent from the comparison section 18 are judged, and if a matching block exists as a result, the process proceeds to step S5,
If this is not the case, the process proceeds to step S6.

In step S5, based on the result sent from the comparing section 18, the last character information of the matching block stored in the second information section 17 is stored in the area in the confirmed information section 20 corresponding to the starting position of the matching block. Stored.

In this embodiment, since the first block of the processed line and the first block of the previous line match, the first block column in the second information section 17 is placed at the first character position in the confirmed information section 20 in step S5. The final character information is written as shown in FIG. 6D.

In step S6, the margin, indent, and European information are read out from one line of information in the line buffer 14, and the information is written in the corresponding area in the definite information section 20 (FIG. 6E).

In step S7, the print control section 21 prints out the information in the row buffer 14 based on the control signal C5. Specifically, the type of each character in the line buffer 14 is determined based on the data in the confirmation information section 20, and the type is output accordingly.

In this embodiment, the first and thirteenth
The Roman information “Europe” is stored in the position, and the fourth
Since the Japanese language information "Japanese" is stored in the 10th position, the 1st to 3rd and 14th to 14th positions in the second row
Each character at the 17th character position is output as a Roman character,
Further, each character in the 5th to 8th and 11th to 12th character positions is output as a Japanese sentence.

When step S7 is completed, the process proceeds to step S8.

In step S8, the block data creation unit 22 searches the confirmed information unit 20 based on the control signal C6,
Of the information stored in the information section 20, the start and end character position information of each block and the final character information of each block are written into the second information section 17.

In this embodiment, as is clear from FIG. 6E, the first
It consists of a first block in which the 8th to 8th character positions constitute one block area, and a second block in which the 10th to 17th character positions constitute one block area, and the last character of each block is divided into Japanese and European characters, respectively. Therefore, the contents of the second information section 17 are as shown in FIG. 6F.

When step S8 is completed, the process returns to step S1, and the third line in FIG. 6A is processed.

Note that although the present embodiment has been described using print processing as the line-by-line processing, the present application is not limited to this.

Furthermore, it goes without saying that the gist of the present application is not limited to the embodiments, and that various changes can be made.

(F) Effects of the Invention According to the present invention, it is possible to process a sentence containing a mixture of European and Japanese texts and consisting of a plurality of blocks on a line-by-line basis, so it can be said to have great practical effects.
