Description

[Detailed Description of the Invention] 3. Detailed Description of the Invention <Industrial Application Field> The present invention is a method for converting Japanese text input in kana or Roman characters into a text containing Kanji and kana characters, and printing the Japanese text, particularly sequentially. The present invention relates to a character processing device for printing.

<Prior Art> Conventionally, in a character processing device that converts a Japanese text input in kana or Roman letters into a text containing Kanji/kana and prints it, the kana/kanji conversion process and the printing process have not been synchronized. In other words, when performing sequential printing in which a desired amount of character information is printed while performing kana-kanji conversion on the input character information, the homophone search for the kana-kanji conversion may be performed even if the printing has already been completed. Regardless of the text, the input character information was started from the beginning of the sentence. Therefore, considering that the portion that has already been printed during sequential printing is a Japanese sentence for which the selection of homophones by homophone search has been completed, extra operations and time are required for the kana-kanji conversion process.

<The problem to be solved by the invention is that in a character processing device that converts Japanese text input in Japanese kana or Roman characters into a text containing Kanji and Japanese characters, and prints it, the kana-kanji conversion process and the printing process are not synchronized. Therefore, homophone search, which is one of the kana-kanji conversion processes, is always started from the beginning of the text of character information input to the character processing device.

This also applies to character-by-letter printing, in which an arbitrary amount of character information is printed while performing kana-kanji conversion in the printing process. The executed portion is also processed as a homophone search target. Therefore, in the kana-kanji conversion process, there is a drawback that unnecessary operations and processing time are required.

Means and operation for solving problems> In the sequential printing mode for sequential printing, by distinguishing between the printed portion of input character information and the unprinted portion, it is possible to performs a homophone search only for character information in unprinted parts. This solves the drawback that homophone search, which is one type of kana-kanji conversion, requires extra operations and processing time in the sequential printing mode, and makes it possible to improve the efficiency of the kana-kanji conversion process.

<Example> The present invention will be described in detail below based on the drawings.

Stored in OM. The RAM is a readable/writable memory that stores information from each component, such as character information input from the keyboard KB. Also, there is a pointer memory PM inside, which stores information indicating the position of the border between the printed part and the unprinted part of the character information input from the keyboard KB in the read/write memory 1'tAM. It is used to store. This is a KB\i keyboard, in which a group of six keys for inputting various data and issuing instructions in a character processing device are configured and arranged as shown in FIG. 2, which will be described later.

OR is a cursor register, which is a memory that is controlled by the microprocessor CPU to write and read data related to the cursor position, and the address stored in this cursor register CR and the display on the display screen of the display CRT. The positions are corresponding. In the present invention, the display surface of the display CRT is assumed to correspond to a document page to be printed out, and the display position on the display surface corresponds to the line and column of each document.

Further, it is assumed that each page of the document is composed of the same number of lines, and for the sake of simplicity, the description will be made assuming that the page is displayed with 20 columns in the horizontal direction and 5 lines in the vertical direction. PRT is a grimmer which prints out the contents of the eight-color readable memory RAM and the display buffer DBUP under the control of the microprocessor CPU.

DBUF is a display buffer and is used as a refresh memory for the display CRT, and the microprocessor c
It can be freely read and written by pσ, and the information is stored in the same state as displayed on the display CRT. Therefore, the display on the display CRT is a display of 20 horizontal columns and 5 vertical lines as described above. 0RTO is a CRT controller that controls the display of a cursor, characters, symbols, etc. on the display CRT based on the cursor position and character/symbol information stored in the cursor register OR and display buffer DBUP.

A CRT is a display device using a cathode ray tube or the like, and a dot-configured display pattern and a cursor 6 display on the CRT display device are controlled by a CRT controller. Furthermore, C
G is a character generator which generates character signals such as characters and symbol cursors to be displayed on the display CRT, and each character symbol has a dot configuration of, for example, 16×16. D119 is an external memory for storing created documents.

FIG. 2 shows an example of the configuration and arrangement of the keyboard KB shown in FIG.

8C is the search key used when performing a homophone search to search and confirm the homophone IItj, 8T is the selection key when selecting a homophone, and PT is the print key when printing. The key PM is a print mode key for switching the print mode between batch printing and sequential printing.

The operation of the above configuration will be explained. FIG. 3 is a main flowchart of the character processing device of the present invention. When this device is powered on, it first proceeds to step S1 in FIG. 3. In step B1, initialization processing is performed to clear the read/write memory RAM, display buffer DBUIF, etc. Thereafter, the process proceeds to step S2, and the state of waiting for the key input from the keyboard KB shown in FIG. 2 is maintained. If some key is pressed manually, proceed to step 83.
The input key is determined, and steps 84 to S10
Proceed to one of the steps.

Step S4 reads the character symbol information input from the keyboard KB and creates a memo! Performs processing for storing character information in the JRAM area. Step 85 performs a search process in Kana-Kanji Henbaku. This is the search key SC
Upon input of , the contents of the dictionary in the fixed memory ROM are compared with the contents of the input document information, and a process is performed in which the matched character strings are recognized and treated as a series of words. In step S6, by inputting the selection key 13T-i for the character string recognized as a series of words in the previous step S5, homophone digraphs are output one after another, and desired characters are selected and converted. Process. In step S7, the cursor is moved according to instructions from cursor keys (not shown) present on the keyboard KB or the like. The contents of the cursor register OR are updated according to the cursor movement at this time. In step S8, the document information input to the device is printed out under the control of the microprocessor cpσ. Step S9 performs a process of manually inputting new document information into the already input document information. Step 810 performs a process of deleting unnecessary information such as characters and symbols from the input document information from the read/write memory RAM of the device. Above steps S4 to Step 8
When the process in step S10 is completed, the process returns to step S2. In such a 70-chart, certain steps related to the KFjA of the present invention include the search process in step S5 and the step B6.
The conversion process in step 8B and the printing process in step 8B.

First, the printing process in step S8 is shown in detail in Figure 4 (
a) Show K.

First, in step 1320, the print mode is determined. This means that batch printing has been selected by operating the print mode key PM, but if batch printing has been selected, the process proceeds to step 321; By operating the print key FT, all of the document information stored in the read/write memo IJ RAM is read out and printed out by the printer PRTK under the control of the microprocessor CPH. If sequential printing is selected, the process advances to step 822. In step 822, a pointer is set to the last part of the document information to be printed out.

As an actual operation example, place the cursor on the last part of the document information that you want to print sequentially, and then operate the print key FT or line feed key (not shown). A process is performed to store information indicating the part in the pointer memory PM. and step 823
Here, in step 822, the pointer memory P
The character information up to the position indicated by the information stored in M is printed out by the printer PRT.

Next, the search process for step day 5 will be explained based on the flowchart shown in FIG. 4 (1). If the key input at step 82 in FIG. 3 is search key date C, the process proceeds to step S5 as determined in step S3. Then, in step 830, it is determined whether sequential printing is selected. If sequential printing is specified, step 83
Otherwise, in the case of batch printing, the process advances to step 833. In step 831, it is determined whether or not there is information in the pointer memory PMK indicating the end of a portion that has already been printed in the document information in the read/write memory RAM during sequential printing. As a result of the determination, if information indicating the end of the document information that has already been printed is stored in the pointer memory PM, the process advances to step 852; otherwise, the process advances to step 1333.

In step 1332, search processing is performed for sentence vIr information after the position indicated by the pointer memo 17 PM among the document information in the readable/writable memory RAM.

Step 853 is a readable and writable memo! Search processing is performed from the beginning of the document information in JRAM. Step S'+2
The specific operation will be explained with reference to FIG. FIG. 5 is a diagram showing the state of search processing on the display device CRT. In the figure, XS is a cursor. Figure 5 (a
), the document "is." is displayed as a part for which the printing process has already been completed. Although not shown in this figure, a symbol indicating that the printing process has been completed may be displayed at the last position of the document information that has been sequentially printed. The document information that is displayed after "Deoru." has only been input, so it is all marked with an upper line, as shown in the figure. At this point, if you press the search key SC for kana-kanji conversion, 8 will appear on the cursor as "tb>" in Figure 5.
Move to "ra". This is the result of a dictionary search where ``however'' was recognized as a series of words.

In this case, there is no need to write ``however'' in kanji, so use the search key 80 to search for the next homophone.
If you press , you will move to the next kana-kanji conversion target word.
“However,” as in (C) and (a) in Figure 5.
The upper line disappears, and the cursor moves to the ``i'' of ``Mondai'' as a result of the dictionary search.

To convert "Mondai" into kanji, press the selection key BT, and when the desired word is displayed as shown in Figure 5(e), press the search key again to search for the next homophone. When you press SC, the cursor will change to “
Stop at ``ha'', ``Mondai'' is converted to ``problem'', and the ``-'' line is deleted.The following ``wa'' and ``,'' do not need to be converted, so search key sc 1
By pressing the button, the upper line disappears, the cursor KS advances, and the message ``However, there is a problem'' is registered.

As described above, in sequential printing, the iR report indicating the last position of document information that has already been printed is stored in the pointer memory PM.
The pointer memory P is stored in the pointer memory P when executing the search process.
By looking at the contents of M, search processing is performed only on the document information after the position indicated by grain intermemo 17 PM, so it is possible to skip the part that has already been printed, and the search processing efficiency can be improved. .

Next, a second embodiment will be described. Figures 1-2 show character processing according to the second embodiment of the present invention! ! FIG. The only difference from FIG. 1-1 is the read/write memory RAM and print processed buffer PB I:rF; other components are the same, so only the read/write memory IJ RAM and print processed buffer FBUP will be explained. Readable/writable memory RAM1f In Figure 1-1, pointer memory PM
However, in this embodiment, pointer memo 1.
I PM does not have it. Print processed buffer PEUF
Of the text 4F information inputted from the keyboard KB and stored in the readable OT syndrome memory RAM, the information for which printing has been completed is transferred from the readable memory RAM and stored. Next, the operation of the character processing device of the second embodiment will be explained. The main flow of the operation is the same as the chart 70 in FIG. 3 shown above, and the difference from the first embodiment is the search process in step S5 and step S8
Since this is the printing process, we will explain these in detail.

First, the print process in step S8 will be described. FIG. 6 is a flowchart showing the print process in the second embodiment of the present invention. Once the printing process begins, step 8
Proceed to 40. Here, it is determined whether the print mode is batch printing or sequential printing. If -pattern printing is specified, the process proceeds to step 841, and if sequential printing is specified, the process proceeds to step sa2. In step 841, all the document information stored in the read/write memory RAM is printed out by the printer PRτ under the control of the microprocessor OFσ. Step 5a Memo + 7 RAM that can be read and written under the control of the 2TH microprocessor CPU
Out of the document information stored in , the part designated for sequential printing is printed out on the printer PRT, and the process proceeds to the next step +343. In step 843, the document information printed sequentially in step B42 can be read and written! Print processing completed from J RAM (Zuffa PBUI'
Perform the process of moving to. Also, the actual operations for batch printing and sequential printing at this time are jj! It is assumed that this is the same as the 11th embodiment.

Next, the search process will be described, and the operations of the search key aC and selection key ST are the same as those described above in FIG. 5. However, in the second embodiment, search processing is performed only for document information in the read/write memo IJ RAM. Finally, in the second embodiment, during sequential printing, the document information stored in the read/write memory RAM that has been printed is stored in the print processed buffer FBCr? Of the document information, it is important to distinguish between printed and unprinted document information, and search processing, which is one of the kana-kanji conversion processes, is carried out in the Yomibara Memo IJ RAM. Execute on document information. Therefore, the search process is performed only on document information that has not yet been printed, and document information that has already been printed can be skipped, making it possible to improve the efficiency of the search process.

<Effects of the Invention> As explained above, among the document information input into the device by using the character processing device fRt'' of the present invention, there are two types of document information that have been printed and those that have not yet been printed. This makes it possible to perform a homophone search, which is a type of kana-kanji conversion when sequential printing is selected, from the beginning of the part of the document information that has not been printed. If the printing process has already been completed, the homophone search can be skipped for document information that has already been printed.Therefore, when sequential printing is selected, unnecessary operations are required in the homophone search for kana-kanji conversion. This makes it possible to reduce the processing time for kana-kanji conversion.Therefore, it is possible for the operator to improve the operability of kana-kanji conversion.
