Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a German language document processing device, in which a German-German dictionary memory is provided as a spell check/candidate word search dictionary memory, and this dictionary memory is used through code data conversion. This book is about things that can be applied to Swiss German as well.

[Prior art]

Conventionally, German document processing devices, such as word processors and typewriters, are equipped with a German dictionary memory to check the spelling of each word, search for candidate words related to misspelled words, and display them on a display. It is widely used in practical applications.

By the way, there are some differences between the German language used in Germany and the Swiss German language used in Switzerland.
Since rssJ is used in Swiss German instead of "β" (eszett) in German German, the document processing device for German German is equipped with a dictionary memory that stores a large number of German words. The processing device is provided with a dictionary memory containing a large number of Swiss German words. Note that the keyboard of a German document processing device is usually fixedly set for German German or Swiss German by connecting specified terminals of the input/output board with solder points at the manufacturer's side before shipping. If you want to make it applicable to both German and Swiss German, you can configure it so that it can be set alternatively using a keyboard setting changeover switch.

[Problem to be solved by the invention]

As mentioned above, it is not possible to share the German dictionary memory with the German document processing device and the Swiss German document processing device, so the German document processing device that can be applied to both German and Swiss German has A German-German dictionary memory and a Swiss-German dictionary memory must be provided. Therefore,
Problems include doubling the capacity of the German dictionary memory and increasing production costs.

SUMMARY OF THE INVENTION An object of the present invention is to provide a German document processing device in which a German dictionary memory can be applied to both German German and Swiss German.

[Means for Solving the Problems] As shown in the functional block diagram of FIG. 1, a German document processing device according to the present invention includes an input means for inputting characters and symbols for German and various commands; a display means capable of displaying a plurality of character strings; a word buffer that sequentially receives and stores word data input or stored in a memory in advance;
A dictionary memory that stores spelling information for a large number of German words, a spell check means that receives word data from a word buffer and performs a spell check on each word via the dictionary memory, and a spell check means that detects spelling errors that are determined to be misspelled by the spell check means. A German language document processing device comprising a candidate word search means for searching a dictionary memory for a candidate word related to a misspelled word, and a display control means for displaying the searched candidate word on a display means. a setting means for selectively setting for German or Swiss German; and rssJ included in the data of each word received from the word buffer when the input means is set for Swiss German in the setting means. first data conversion means converting the code data of rBJ into code data of rBJ and supplying the data of each word to the spell check means and the candidate word search means; and the data of the candidate words searched by the candidate word search means. and a second data conversion means for converting code data of "β" included in code data of rSSJ.

[Effect]

In the German language document processing device according to the present invention, basically, the words stored in the word buffer one after another are spell-checked by the spell-checking means via the dictionary memory, and when a misspelled word is found, the candidate word searching means is used to check the spelling of the words. Candidate words are searched through the dictionary memory and displayed on the display means.

Here, since German words are stored in the dictionary memory, when the input means is set for German German by the setting means, spell checking and candidate word searches can be performed without any problem.

When the input means is set for Swiss German, the first data conversion means converts the rs SJ code data included in the word data to enable spell checking and candidate word searches using the German German dictionary memory. Convert to "β" code data (convert to German word)
The data for each word is supplied to spell check means and candidate word search means. Furthermore, since the candidate words retrieved from the dictionary memory are German German words, the second data conversion means is included in the candidate word data in order to convert them into Swiss German words and output or store them in the memory. Convert the code data of "β" that is included into the code data of "ss".

〔Effect of the invention〕

According to the German document processing device according to the present invention, the German document processing device includes a German-German dictionary memory and spell check and candidate word search functions, and includes a setting device, a first data conversion device, and a second data conversion device. By providing this, it becomes possible to process documents by applying the German-German dictionary memory even to words input in Swiss German.

In other words, it is possible to omit the Swiss-German dictionary memory from the dictionary memory, thereby reducing the capacity of the dictionary memory and reducing its manufacturing cost.

〔Example〕

Hereinafter, embodiments of the present invention will be explained based on the drawings.
This embodiment is a case where the present invention is applied to an electronic typewriter for German language.

As shown in FIG. 2, a keyboard 3 is disposed at the front of the main body frame 2 of the electronic typewriter 1.
A daisy-wheel type printing mechanism PM is disposed within the main body frame 2 at the rear of the main body frame 2.

Further, a liquid crystal display 10 capable of displaying one line of a plurality of words is disposed on the main body frame 2.

The keyboard 3 has character keys including German alphabet keys, numeric keys, and symbol keys, a space key, a return key, cursor movement keys for moving the cursor on the display 10 left and right, and a spell check mode. Alternatively, a spell check mode setting key for canceling the spell check mode and various other function keys are provided.

Furthermore, the keyboard 3 is provided with a keyboard setting switch 30 (see FIG. 3) for selectively switching the keyboard between German German and Swiss German. Note that when set for Swiss German, input from the character key "β" (estuette) is invalid.

The printing mechanism PM includes at least a platen 4 that feeds printing paper, a stepping motor that drives it, a carriage 5 that is supported by a guide parallel to the platen 4, a stepping motor that drives it back and forth in the left and right direction, and a wheel cassette. A type wheel 6 housed in the type wheel 6 and a stepping motor that drives it, a type ribbon 8 housed in the ribbon cassette 7 and a stepping motor that winds it, a solenoid 9 that hits the type on the type wheel 6, etc. are provided. The stepping motor and solenoid 9 are each driven by a drive signal from a drive circuit.

Next, the control system of this electronic typewriter 1 is constructed as shown in the block diagram of FIG.

The display mechanism DM includes a liquid crystal display IO and a display RAM for outputting display data to the display 10.
and a display controller 11 including a character generator ROM storing a large number of dot patterns such as characters and symbols. Incidentally, the symbol AM is an alarm mechanism including a buzzer 12 and its drive circuit 13.

The control device C includes a CPU 16, an input/output interface 14 connected to the CPU 6 via a bus 15 such as a data bus, ROMs 17 and 18, and a RAM 20.

The program memory of the ROM 17 includes a control program that controls the display mechanism DM and the printing mechanism PM in response to code data input from the keyboard 3, and the code data is stored in the input data buffer 21, text memory 22, and word buffer 23. A cursor movement control program that moves the cursor according to the operation of the cursor movement keys, an initial setting processing control program that initializes the printing mechanism PM, etc. immediately after power is turned on, a spell check/candidate word search control program, etc. has been done.

The spell check/candidate word search control program includes a spell check processing subroutine for executing a spell check process for each word input or previously input and stored in the text memory 22, and a dictionary for searching candidate words related to misspelled words. A candidate word search processing subroutine for searching from memory 18 is included.

In the German language dictionary memory of the ROM 1B, spelling data relating to, for example, about 70.000 German words is stored in alphabetical order in the same way as a normal dictionary, in order to check the spelling of German words.

Here, since the spell check process is a well-known and general process, it will be briefly explained. is inputted and stored in advance in the text memory 22 via the input data buffer 21 from the text memory 22.
RO for each word supplied to the word buffer 21 from
The spelling is checked by comparing it with a large number of words stored in the M1B's dictionary memory.

Candidate word search processing is a well-known and general process, so to briefly explain it, it is sequentially and repeatedly searched to see if a word in which each letter of the misspelled word is replaced with each letter of the alphabet exists in the German dictionary memory 18, or This search is performed by replacing character strings based on rules that make misspellings easier with similar pronunciations, etc., and searches for correctly spelled candidate words related to misspelled words.

The RAM 20 contains 1 which is input in sequence from the keyboard 3.
The input data buffer 21 stores the document data for each line while updating it (however, normally, this data is displayed on the display 10), and the input data buffer 21 supplies data in sequence during the store mode. A text memory 22 that cumulatively stores document data line by line.
When in the spell check mode, word data for one word is sequentially supplied from the input data buffer 21 in the typewriter mode or L/L mode, or is sequentially supplied from the text memory 22 in the store mode. A word buffer 23 that stores word data for one word, a candidate word memory 24 that stores data of one or more candidate words for each misspelled word each time the candidate word is searched, and supply to the display controller 11. a candidate display buffer 25 that stores data of one or more candidate words to be passed; a word pointer memory 26 that stores a word pointer WP that sequentially indicates candidate words in the candidate word memory 24 starting from the first one; A keyboard flag memory 27 stores a keyboard flag KF (KF=0: for German German, KF=1 for German German) indicating the setting state of the keyboard 3 set by the keyboard setting switch 30, and a flag indicating a spell check mode. A spell check mode flag memory 28 for storing the spell check mode flag and various other buffers and memories are provided.

Next, a flowchart of a spell check and candidate word search control routine will be described with reference to FIGS. 4 to 6. Note that the symbol Si (i=1.2, . . . ) in the figure indicates each step.

As shown in FIG. 4, when the control is started after the power is turned on, general initial settings are executed in Sl, and the signal from the keyboard setting switch 30 is read. The keyboard flag KF=O is set, and when the setting is for Swiss German, the keyboard flag KF=1 is set.

Next, initial settings of the printing mechanism PM are performed, such as setting the origin position of the carriage of the printing mechanism PM and the origin position of the type wheel 6 (S2).

Next, a key scan for keyboard 3 is executed (
S3) If there is human power on the key, the process corresponding to the operated key is executed in the same way as on a normal electronic typewriter (S4
). When the operator operates the spell check mode setting key, the spell check mode flag 28 is set, and the following description will be made assuming that this spell check mode has been set. Here, typewriter mode and L/
In the L mode, the code data of characters input by key operations are input in sequence to the input data buffer 21, and the delimiter code (space, comma, semicolon, colon, period, etc.) following the last character of a word is input. Then, word data for the latest word in the input data buffer 21 is written to the word buffer 23, and the word data of the latest word in the input data buffer 21 is written to the word buffer 23.
Spell check processing and candidate word search processing will be executed for the words in 3.

Next, in S5, it is determined whether or not it is a delimiter code, and No.
If so, the process returns to S3, and if Y'es, a subroutine for spell checking and candidate word search processing (see FIG. 5) is executed in S6.

The subroutine of spell check and candidate word search processing will be explained using the flowchart of FIG. 5. First, word data is read from the word buffer 23 (S20).
), then it is determined whether or not there is an error in the word data (that is, whether or not code data of numbers and symbols is included) (S21), and if there is an error, a buzzer is sounded via the drive circuit 13 in S22. 12 is activated, and the process returns to the main routine shown in FIG. If there is no error, it is determined whether the keyboard flag KF=1 (S23),
When keyboard 3 is set for German German (K
When F=O), the process moves to S26, and the keyboard 3
is set for Swiss German (KF=1), the code data of rssJ (that is, the code data of two rs' are included consecutively) is included in the word data in S24. It is determined whether the word exists or not, and if Yes, the code data of 'SSJ included in the word data is converted to the code data of "β" (Eszet) (325). That is, this is to check the spelling using the German spelling stored in the German dictionary memory 18. On the other hand, when the result of the determination in S24 is No, S26
Move to.

In S26, a spell check process is performed on the word data using the German dictionary memory 18. Next, it is determined whether or not there is a misspelling as a result of the spell check process (S27). If No (7), the process returns to the main routine shown in FIG. Candidate word search processing is performed to search for candidate words related to the misspelled word.

Next, data of one or more candidate words obtained in the candidate word search process is stored in the candidate word memory 24 (S29
), then the number of candidate words is the maximum value WP of the word pointer WP
M and stored in the memory of the RAM 20 (S30
), then code conversion processing is executed at 331, after which the process returns to the main routine of FIG.

The subroutine of the code conversion process will be explained with reference to the flowchart of FIG.
"1" is written to P (340), and then the word pointer W
Data of the candidate word specified by P is stored in the candidate word memory 24.
(341), and then it is determined whether or not the keyboard flag KF is set (S42). (S43), it is determined whether there is code data for "β" (eszett) in the code data of the candidate word.
If Yes, the code data of "6" is code-converted to the code data of rssJ (S44), and then S4
Move to 5. That is, when the keyboard 3 is set for Swiss German, candidate words in German German are converted into Swiss German. On the other hand, if the result of the determination in step 343 is No, then the process moves to step 345 because "rB" is not included and there is no need for conversion.

Next, the data of the candidate word is stored in the candidate word display buffer 25 (345), and then the word pointer WP is set to "
1” (S46), then WP=W
It is determined whether PM+1 or not (S47), and if no, 3
Steps 41 to S46 are repeated, and 34 steps are repeated for all candidate words.
When steps 1 to S46 are completed, the process returns to the main routine shown in FIG.

Next, after executing the spell check and candidate word search processing described above, the process moves to 87 of the main routine in FIG.
It is determined whether or not the word subjected to the spell check (the latest word stored in the word buffer 23) is a misspelled word (S7), and when the answer is No, the process moves to S3, and when the answer is Yes, the buzzer 12 is activated. (S8) Next, the candidate word data stored in the candidate word display buffer 25 is supplied to the display controller 11, and one or more candidate words within the range that can be displayed on the display 10 are displayed on the display 10 ( S9), then the candidate words are displayed on the display 10 until there are no more candidate words.
(S9 510). When a candidate word is selected by operating the cursor movement key and the candidate word select key while being displayed on the display 10, the word data in the word buffer 23 is rewritten with the data of the selected candidate word, and the word data in the word buffer 23 is then rewritten. The corresponding word data in the input data buffer 21 will be rewritten with the word data. After the SIO is executed, the process moves to S3, and the steps after S3 are repeated.

As explained above, the keyboard setting switch 30 is provided to selectively set the keyboard 3 to either German German or Swiss German, and when the keyboard is set for Swiss German, words containing rssj are changed to "rB". The spell check process and candidate word search process are performed to convert the German word containing "β" into a Swiss German word containing "ss" which is a German word containing "β" and which is searched from the dictionary memory 18. Since it is displayed on the display 10, it is possible to process not only German-German documents but also Swiss-German documents without having to provide a Swiss-German dictionary memory other than the German-German dictionary memory 18. An electronic typewriter 1 can be realized.

In addition, in the store mode, words previously input and stored in the text memory 22 are sequentially supplied to the word buffer 23 to perform spell check and candidate word search processing, but when a candidate word is selected to replace a misspelled word. Sometimes, the data of the misspelled word in the text memory 22 is rewritten with the data of the candidate word.

Note that when a user dictionary memory made of RAM is provided as the dictionary memory, it is desirable to perform spell check processing and candidate word search processing on the user dictionary memory using word data that is not subjected to code conversion.

Incidentally, the present invention can be similarly applied to German language document processing devices such as a German language word processor and a German language personal computer.
