Detailed Description of the Invention

[0001]

[Industrial field of use] In the process of creating documents, the Kana-Kanji conversion function, which converts a Kana character string into a Kanji-Kana mixed character string, is widely used for inputting Japanese sentences containing Kanji and Kana characters. .

The present invention relates to a character processing apparatus having a kana-kanji conversion function.

[0003]

2. Description of the Related Art In a character processing device, a kana-kanji conversion dictionary for converting a kana character string into a character string containing kanji and kana stores some words in advance. However, there are various users, and for that user, necessary words are not stored, and on the contrary, unnecessary words are stored. for that reason,
There is a device having a word registration function of registering necessary words in a readable / writable dictionary and a word deleting function of deleting unnecessary words from the dictionary.

In recent years, a kana-kanji conversion dictionary is often stored in a ROM because of advantages such as access speed. ROM
Words cannot be registered or deleted from the Kana-Kanji conversion dictionary that has been converted into Japanese.

Therefore, in order to register a word, a dictionary for registered words is prepared for registered words and registered in this dictionary. Then, it is processed so that the words in the registered word dictionary can also be converted at the time of converting kana-kanji.

On the other hand, although words cannot be deleted from the Kana-Kanji conversion dictionary stored in ROM, unnecessary words are deleted from the Kana-Kanji conversion dictionary by designating words that are not Kana-Kanji conversion (hereinafter referred to as conversion prohibited words). The applicant has proposed a method of obtaining the same effect as the deletion.

[0007]

However, in order to be able to convert the once deleted word, there is no method other than registering the word. Similarly, in order to be able to convert a word that has been once set as a conversion prohibited word, the word had to be registered again.

Further, even if the same word is registered again,
It was not possible to faithfully reproduce the information about the original word.

In order to prohibit conversion into a certain word, first, whether the word is in the registered word dictionary, RO
If it is in the registered word dictionary, the word is deleted from the registered word dictionary.
If it is in the ROM, it is necessary to register the word as a conversion-prohibited word, and the procedure is complicated.

11 to 14 are flowcharts for explaining the process of canceling the conversion prohibited word in the present invention.

The operation of the above embodiment will be described according to the flow.

FIG. 11 is a flowchart of the entire processing. In step S11-1, a key is pressed by the keyboard and an interrupt is awaited. When a key is input, step S11-2 branches to any of steps S11-3 to S11-6 depending on the type of key.

Step S11-3 is a process for deleting a word from the registered word dictionary when the word delete key is pressed. In addition, a process of registering a word in the conversion prohibited word dictionary is also performed depending on the situation. Details will be described with reference to FIG.

Step S11-4 is a process when the word registration key is pressed, and is a process of registering a word in the registered word dictionary. Also, depending on the situation, the process of deleting a word from the conversion prohibited word dictionary is also performed. Details will be described with reference to FIG.

Step S11-5 is a process when the conversion key is pressed, and is a process for performing kana-kanji conversion.
Details will be described with reference to FIG.

Step S11-6 is a process when an ordinary key (for example, a character key or a cursor movement key) other than the above is input, and is a process generally performed in a character processing device of the same kind, and is known. Therefore, it is not particularly described.

FIG. 12 is a detailed flowchart of the word deleting process (step S11-3) according to the present invention.

Step S12-1 is a notation / reading input process. In this process, the screen of FIG. 2 is displayed,
This is a process for allowing the operator to input the notation and reading of the word to be deleted. Based on the input information, step S12-
In step 2, the registered word dictionary TOUROKU is searched. Since the registered word dictionary is sorted in the order of reading the words, first, the reading is searched as a key. When there is a word with the same reading, the notation is further compared. reading,
When there is a word that matches the notation, it is assumed that the corresponding word exists. As a result of the search, if there is a corresponding registered word in step S12-3, step S1
It branches to 2-4, and when it does not exist, step S12-7
Branch to.

Step S12-4 is a registered word deletion confirmation process. In this process, the screen of FIG. 4 is displayed and the operator is asked to confirm the deletion. On this screen, information held by the word retrieved in step S12-2 is displayed. Therefore, in addition to the information input in step S12-1, information on the part of speech and frequency is also displayed. The operator looks at this and inputs a yes key or no key. Depending on the entered key, step S
Depending on 12-5, the process branches to step S12-6 or step S12-7.

Step S12-6 is a registered word deletion process. In this process, the word searched in step S12-2 is deleted from the registered word dictionary TOUROKU. Deletion means filling the area of the corresponding word from the registered word dictionary TOUROKU and performing a memory transfer of the words after the next existing word, but this is known in the commonly used processing. Not described in detail.

Step S12-7 is a kana-kanji conversion dictionary search process. Based on the information input in step S12-1, the Kana-Kanji conversion dictionary DIC is searched. Since the kana-kanji conversion dictionary is sorted in the order of reading the words, first, the pronunciation is used as a key to search. When there is a word with the same reading, the notation is further compared. If there is a word that matches the reading, it is assumed that the corresponding word exists. As a result of the search, step S
According to 12-8, when the corresponding word exists, the process branches to step S12-9, and when it does not exist, there is no word that should be the conversion prohibited word, so the word deletion processing ends.

Step S12-9 is a conversion prohibited word registration confirmation process. In this process, the screen of FIG. 5 is displayed and the operator is asked to confirm the registration. On this screen, the information possessed by the word retrieved in step S12-7 is displayed. Therefore, in addition to the information input in step S12-1, information on the part of speech and frequency is also displayed. The operator looks at this and inputs a yes key or no key. Depending on the entered key, step S
According to 12-10, the word deletion processing is ended, or the process branches to step S12-11.

Step S12-11 is conversion prohibited word registration processing. In this process, step S12-
The word searched from the kana-kanji conversion dictionary DIC in 7 is added to the conversion prohibited word dictionary NOTCNV. Although adding a word to the dictionary is the following process, it is a process that is generally widely performed and is well known, so a detailed description thereof will be omitted.

A position to be added in the dictionary, that is, an address is detected according to the format of the conversion prohibited word dictionary.

The data of all the words existing after the above address is transferred backward to the memory by the data size of the word to be added.

Data of the word to be added is transferred to the area after the above address in the memory. When this process ends, the word deletion process ends.

As described above, according to the present embodiment, the user can delete a word if it is in the registered word dictionary by instructing deletion of the word without being aware of where the word is stored. , If it is in the Kana-kanji conversion dictionary that cannot be deleted, it is registered as a conversion prohibited word. Therefore, in either case, the same effect as that of deleting this word can be obtained in the subsequent conversion.

FIG. 13 is a detailed flowchart of the word registration process (step S11-4) according to the present invention.

Step S13-1 is a notation / reading / part of speech / frequency input processing. In this process, the screen of FIG. 3 is displayed, and the operator is prompted to enter the notation / reading / part of speech / frequency of the word to be registered. Based on the input information, the conversion prohibited word dictionary NOTCNV is searched in step S13-2. Since the conversion prohibited word dictionary is sorted in the order of reading the words, first, the reading is used as a key to search. When there is a word with the same reading,
Furthermore, the notation, part of speech, and frequency are compared. When there is a word having the same reading, notation, part of speech, and frequency, it is assumed that the corresponding word exists. As a result of the search, step S13-3
Thus, when the corresponding conversion prohibited word exists, the process branches to step S13-4, and when it does not exist, step S1.
Branch to 3-7.

Step S13-4 is a conversion prohibited word cancellation confirmation process. In this process, the screen of FIG. 6 is displayed and the operator is asked to confirm the cancellation. The operator looks at this and inputs a yes key or no key. Depending on the entered key, step S13-5 or step S13-6 or step S13-7 is performed.
Branch to.

Step S13-6 is a conversion prohibited word deletion process. In this process, step S13-2
Conversion prohibited word dictionary NOTCNV
Remove from. To delete means to fill the area of the corresponding word from the conversion prohibited word dictionary and to transfer the words after the next existing word to the memory, but this is not known because it is well known in the general processing. . When this process ends, the word registration process ends.

Step S13-7 is a registered word registration confirmation process. In this process, the screen of FIG. 7 is displayed and the operator is asked to confirm the registration. The operator
Look at this and enter the Yes or No key. Depending on the entered key, the word registration process is completed in step S13-8, or step S13-
Branch to 9.

Step S13-9 is a registered word registration process. In this process, the word input by the operator in step S13-1 is added to the registered word dictionary TOUROKU. In step S13-1, the feature of the word cannot be input, so that the word to be added to the registered word dictionary has no feature portion.
The addition means the following processing, but it is a processing that is generally widely performed and is well known, so a detailed description thereof will be omitted. Detect a position to add in the dictionary, that is, an address according to the format of the registered word dictionary. -Transfer the data of all the words existing after the above address to the memory backward by the data size of the word to be added. -Transfer the data of the word to be added to the area after the above address.

When this process ends, the word registration process ends.

As described above, according to the present embodiment, the user instructs the word registration without being aware of whether or not the word is stored in the conversion prohibited word dictionary. If so, it is deleted from this dictionary and is no longer a conversion prohibited word. If it is not in the conversion prohibited word dictionary, it is registered in the registered word dictionary. When it is deleted from the conversion prohibited word dictionary, information about this word before it is regarded as a conversion prohibited word becomes available.

FIG. 14 is a detailed flowchart of the kana-kanji conversion processing (step S11-5) in the present invention.

The kana-kanji conversion is a process for converting a kana character string into a character string containing kanji and kana. The kana character string to be input is the step S11 when the character key is input.
In the other processing of -6, it is stored in the area on the RAM, and it is stored in step S14-1 and step S14-
2. Since the above is the processing that is generally performed, detailed description is omitted.

Step S14-1 is a kana-kanji conversion dictionary search process. In this process, the kana character string stored in the RAM is used as a reading, and words having the same reading are searched from the kana-kanji conversion dictionary DIC. The reading is
It does not necessarily have to be an exact match with the kana character string, but may be a partial match from the beginning. The term "partial match" used here means that if the input kana character string is "○ △ □", there are words with a reading of "○ △" or words with a "○" in the kana-kanji conversion dictionary. . Sometimes both exist, or there are multiple words with the same reading. In such a case, multiple searches are performed.

Step S14-2 is a registered word dictionary search process. This process is exactly the same as step S14-1 except that the search target is the registered word dictionary.

As a result of the search, by step S14-3,
When no corresponding word exists, step S1
If it exists, the process branches to step S14-4.

Step S14-4 is a conversion prohibited word dictionary search process. This process searches whether or not the same word as the word searched in step S14-1 or step S14-2 exists in the conversion prohibited word dictionary NOTCNV. When there are a plurality of words searched for in step S14-1 or step S14-2, the search is performed for all of them. Since the conversion prohibited word dictionary is sorted in the order of reading the words, first, the reading is used as a key to search. If there is a word with the same reading, write it further.
Compare parts of speech and frequency. When there is a word having the same reading, notation, part of speech, and frequency, it is assumed that the corresponding word exists.

Step S14-5 is a search result determination process. In step S14-4, the result of searching the conversion prohibited word dictionary is determined as follows, and the process is branched. When all the words searched in step S14-1 or step S14-2 are present in the conversion prohibited word dictionary, the same handling is performed as when no words are present in the kana-kanji conversion dictionary or the registered word dictionary. To step S
It branches to 14-6. Step S14-1 or Step S
If there is a word that does not exist in the conversion prohibited word dictionary among all the words searched in 14-2, the process branches to step S14-7.

Step S14-6 is a process for outputting the input character string as it is. This means that the kana-kanji conversion could not be performed, and the kana character string is output and displayed.
After that, the kana-kanji conversion processing ends.

Step S14-7 is a kana-kanji conversion output process. Step S14-1 and step S14-2
Of all the words searched for in step S14-4, the words that do not exist in the conversion prohibited word dictionary in step S14-4 are output targets. Although there may be a plurality of words, in such a case, the processing for determining the most optimal word is performed by using the frequency of the word and the information of the characteristic part.
Then, the notation of the word is output and displayed. this is,
It means that kana-kanji conversion was successful. After that, the kana-kanji conversion processing ends.

As described above, even if a word exists in the kana-kanji conversion dictionary, if a word having the same information as that exists in the conversion prohibited word dictionary, the word is not converted into kana-kanji conversion. Then, by deleting the word registered as the conversion prohibited word from the conversion prohibited word dictionary, it is possible to return to the state in which kana-kanji conversion is possible.
At this time, the characteristic part stored in the kana-kanji conversion dictionary can be restored and made effective. Further, in the present embodiment, the function of deleting a word from the conversion prohibited word dictionary is realized by automatically determining whether or not the word is in the conversion prohibited word dictionary in the process of registering a registered word. The operator can operate as if registering a word.

(Second Embodiment) In the first embodiment, a conversion prohibited word dictionary is provided in order to set a word in the kana-kanji conversion dictionary as a conversion prohibited word, and information such as reading and notation of the word is provided in dictionary form here. Although it is registered, in the present embodiment, instead of this, the address of the conversion prohibited word in the kana-kanji conversion dictionary is stored.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 15 shows an example of the entire structure of the present invention. The difference from FIG. 1 is that a conversion prohibited word address area NOTSRC is provided on the RAM instead of the conversion prohibited word dictionary NOTCNV. Is.

3, S26-4, S26-5, S26-6.

S26-3 is a process when the word delete key is pressed, which is a process of deleting a word from the registered word dictionary. If the word is in the kana-kanji conversion dictionary DIC, the process also registers the address of the dictionary in the conversion prohibited word address area NOTSRC as the conversion prohibited word.
Details will be described with reference to FIG.

S26-4 is a process when the word registration key is pressed, which is a process of registering a word in the registered word dictionary. If the word is a conversion prohibited word, the process also deletes the address of the dictionary registered from the conversion prohibited word address area NOTSRC. Details will be described with reference to FIG.

Step S26-5 is a process when the conversion key is pressed, which is a process for performing kana-kanji conversion. Detail is,
This will be described with reference to FIG.

S26-6 is a process when a normal key (for example, a character key or a cursor moving key) other than the above is input, which is a process generally performed in a character processing device of the same kind, and is known. There is no special description.

FIG. 27 is a detailed flowchart of the word deleting process (S26-3) in the present invention.

S27-1 is a notation / reading input process. In this process, the screen of FIG. 16 is displayed, and the operator is prompted to input the notation and reading of the word to be deleted. Based on the input information, the registered word dictionary TOUROKU is searched in S27-2. Since the registered word dictionary is sorted in the order of reading the words, first, the reading is searched as a key. When there is a word with the same reading, the notation is further compared. When there is a word that matches both reading and writing, it is assumed that the corresponding word exists. As a result of the search, in S27-3, if the corresponding registered word exists, the process branches to S27-4, and if it does not exist, the process branches to S27-7.

S27-4 is a registered word deletion confirmation process. In this process, the screen of FIG. 18 is displayed and the operator is asked to confirm the deletion. In this screen, S
The information possessed by the word retrieved in 27-2 is displayed.
Therefore, in addition to the information input in S27-1, information on the part of speech and frequency is also displayed. The operator looks at this and inputs a yes key or no key. Depending on the entered key, the process branches to S27-6 or S27-7 in S27-5.

S27-6 is a registered word deletion process.
In this process, the word searched in S27-2 is deleted from the registered word dictionary TOUROKU. Deleting means to fill the area of the corresponding word from the registered word dictionary TOUROKU and to transfer the words after the next existing word to the memory. However, this is not known because it is well known in the general processing. .

Step S27-7 is a kana-kanji conversion dictionary search process. Based on the information input in S27-1,
Search the Kana-Kanji conversion dictionary DIC. Since the kana-kanji conversion dictionary is sorted in the order of reading the words, first, the pronunciation is used as a key to search. When there is a word with the same reading, the notation is further compared. If there is a word that matches the reading, it is assumed that the corresponding word exists. As a result of the search, in S27-8, when the corresponding word exists, the process branches to S27-9, and when it does not exist, there is no word to be the conversion prohibited word.
The word deletion process ends.

S27-9 is a conversion prohibited word registration confirmation process. In this process, the screen of FIG. 19 is displayed,
Ask the operator to confirm the registration. On this screen, the information possessed by the word retrieved in S27-7 is displayed. Therefore, in addition to the information input in S27-1, information on the part of speech and frequency is also displayed. The operator looks at this and inputs a yes key or no key. Depending on the entered key, the word deletion process is ended in S27-10, or the process branches to S27-11.

S27-11 is a conversion prohibited word address registration process. In this process, the address of the word retrieved from the kana-kanji conversion dictionary DIC in S27-7 is added to the conversion prohibited word address area NOTSRC. The addition means the following processing, but it is a processing that is generally widely performed and is well known, so a detailed description thereof will be omitted. Detect a position to add in the dictionary, that is, an address according to the format of the conversion prohibited word address area. -Transfer all data existing after the above address to the memory one word backward.・ Substitute the address data to be added into the area after the above address. When this process ends, the word deletion process ends.

FIG. 28 is a detailed flowchart of the word registration process (S26-4) according to the present invention.

S28-1 is a notation / reading / part of speech / frequency input processing. In this process, the screen of FIG. 17 is displayed, and the operator is prompted to enter the notation / reading / part of speech / frequency of the word to be registered. Based on the input information, the Kana-Kanji conversion dictionary DIC is searched in S28-2. Since the kana-kanji conversion dictionary is sorted in the order of reading the words, first, the pronunciation is used as a key to search.
When there is a word with the same reading, the notation, part of speech, and frequency are further compared. When there is a word having the same reading, notation, part of speech, and frequency, it is assumed that the corresponding word exists. As a result of the search, in S28-3, if the corresponding word exists, the process branches to S28-4, and if not, the process branches to S28-8.

S28-4 is an address comparison process.
The address of the word searched in S28-2 is
It is compared whether or not it exists in the conversion prohibited word address area NOTSRC. As a result of the comparison, when there is no S2,
Branch to 8-8. If it exists, the process branches to S28-5.

Step S28-5 is a conversion prohibited word cancellation confirmation process. In this process, the screen of FIG. 20 is displayed,
Ask the operator to confirm the cancellation. The operator looks at this and inputs a yes key or no key. Depending on the entered key, the process branches to S28-7 or S28-8 in S28-6.

S28-7 is a conversion prohibited word address deletion process. In this process, the address data having the address of the word searched in S28-2 is deleted from the conversion prohibited word address area NOTSRC. Deleting means to fill the area of the corresponding address data from the conversion prohibited word address area and transfer the address data after the next existing address data to the memory, but it is known as a generally performed processing. , Not particularly described. When this process ends, the word registration process ends.

S28-8 is a registered word registration confirmation process. In this process, the screen of FIG. 21 is displayed and the operator is asked to confirm the registration. The operator looks at this and inputs a yes key or no key. Depending on the entered key, the word registration process is terminated in S28-9, or the process branches to S28-10.

S28-10 is a registered word registration process. In this process, the word input by the operator in S28-1 is converted into the registered word dictionary TOURO.
Add to KU. In S28-1, the feature of the word cannot be input, so that the word added to the registered word dictionary has no feature portion. The addition means the following processing, but it is a processing that is generally widely performed and is well known, so a detailed description thereof will be omitted. Detect a position to add in the dictionary, that is, an address according to the format of the registered word dictionary. -Transfer the data of all the words existing after the above address to the memory backward by the data size of the word to be added. -Transfer the data of the word to be added to the area after the above address. When this process ends, the word registration process ends.

FIG. 29 is a detailed flowchart of the kana-kanji conversion processing (S26-5) according to the present invention.

The kana-kanji conversion is a process for converting a kana character string into a character string containing kanji and kana. The kana character string to be input is stored in the area on the RAM in the other processing of S26-6 when the character key is input, and is referred to in S29-1 and S29-2.
Since the above is a generally performed process, detailed description thereof will be omitted.

S29-1 is a kana-kanji conversion dictionary search process. In this process, the kana character string stored in the RAM is used as a reading, and words having the same reading are searched from the kana-kanji conversion dictionary DIC. The reading does not necessarily have to exactly match the kana character string, but may be a partial match from the beginning. The term "partial match" used here means that if the input kana character string is "○ △ □", there are words with a reading of "○ △" or words with a "○" in the kana-kanji conversion dictionary. . Sometimes both exist, or there are multiple words with the same reading. In such a case, multiple searches are performed.

S29-2 is a registered word dictionary search process. This process is exactly the same as S29-1 except that the search target is the registered word dictionary.

As a result of the search, if there is no corresponding word in S29-3, the process branches to S29-6,
When it exists, the process branches to S29-4.

S29-4 is a conversion prohibited word address comparison process. This processing is performed in the conversion prohibited word address area N
Whether or not the address of the word searched in S29-1 exists in the OTSRC address data is compared. S2
When there are a plurality of words retrieved in 9-1, comparison is performed for all the retrieved words.

S29-5 is a comparison result judging process.
In S29-4, the comparison result is determined as follows, and the process branches. When the addresses of all the words searched in S29-1 are present in the address data of the conversion prohibited word address area, the same handling is performed as when there are no words in the kana-kanji conversion dictionary or the registered word dictionary. Then, the process branches to S29-6. If there is a word that does not exist in the address data of the conversion prohibited word address area among the addresses of all the words searched in S29-1, the process branches to S29-7.

S29-6 is a process for directly outputting the input character string. This means that the kana-kanji conversion could not be performed, and the kana character string is output and displayed. afterwards,
The kana-kanji conversion processing ends.

Step S29-7 is a kana-kanji conversion output process. Among all the words searched in S29-1 and S29-2, the word whose address is not present in the address data of the conversion prohibited word address area in S29-4 is output. Although there may be a plurality of words, in such a case, the processing for determining the most optimal word is performed by using the frequency of the word and the information of the characteristic part. Then, the notation of the word is output and displayed. This means that the kana-kanji conversion was successful. After that, the kana-kanji conversion processing ends.

As described above, even if a word exists in the kana-kanji conversion dictionary, if the address of the word is stored in the conversion prohibited word address area, the word is not converted to kana-kanji conversion. . Then, by deleting the address data in the conversion prohibited word address area, it is possible to restore the kana-kanji conversion possible state. At this time, the features stored in the Kana-Kanji conversion dictionary are also
It can be revived and effective.

Further, in the present embodiment, the function of deleting the conversion-prohibited word is used in the processing of the operation of registering the registered word.
Since it is realized by automatic discrimination, the operator can operate as if he or she registered a word.

Further, in this embodiment, as the information regarding the conversion prohibited word, the information of the kana-kanji conversion dictionary is stored without having direct information such as word reading, notation, and part of speech. It requires less information.

(Third Embodiment) In the first and second embodiments, the user manually inputs the reading and notation information of the word in order to cancel the conversion prohibition of the word which is the conversion prohibited word. In the present embodiment, a list of conversion prohibited words is displayed and the words are indicated on this display to cancel the conversion prohibition.

Hereinafter, preferred embodiments of the present embodiment will be described in detail with reference to the accompanying drawings.

FIG. 31 is an example of a conversion prohibited word registration screen in this embodiment. This state is a screen displayed when an operation of registering a word that is not desired to be converted into Kana-Kanji, that is, a conversion prohibited word registration operation is instructed. The operator inputs the notation and reading of the word that he / she wants to be the conversion prohibited word.

FIG. 32 shows an example of the registration confirmation screen for the conversion prohibited word in this embodiment. In this state, when each word information in FIG. 31 is input and an execution instruction is further issued, if a word having the same information as the input information is present in the Kana-Kanji conversion dictionary DIC described later, This is a state in which the operator is asked to confirm whether or not to register the word as a conversion prohibited word. In this state, when the operator instructs the Yes key, the word is registered in the conversion prohibited word dictionary described later. If the No key is specified, the conversion prohibited word is not registered.

33 and 34 are examples of screens for explaining the operation of deleting the conversion-prohibited word in this embodiment.

FIG. 33 is an example of a conversion prohibited word list display screen in this embodiment. This state is a screen displayed when an operation of deleting the conversion prohibited word is instructed, and a list of registered conversion prohibited words is displayed.
The operator moves the cursor to the conversion-prohibited word to be deleted and performs a deletion instruction operation. Then, the designated word is deleted from the conversion prohibited word dictionary, and the screen becomes as shown in FIG. 34. It can be confirmed that the designated word is deleted on the display. In this screen example, the conversion-prohibited word whose reading is "stomping" is deleted.

FIG. 35 shows an example of the structure of the kana-kanji conversion dictionary DIC, the word registration dictionary TOUROKU and the conversion prohibited word dictionary NOTCNV in this embodiment. Also,
36 and 37 are a part-of-speech code correspondence table and a feature code correspondence table in the dictionary of FIG. Since these are exactly the same as those described in the first embodiment with reference to FIGS.

Step S38-6 is a process when a normal key (for example, a character key or a cursor moving key) other than the above is input, and is a process generally performed in a character processing device of the same kind, and is known. Therefore, it is not particularly described. Further, in the present embodiment, the conventional word registration processing is possible, and the registered words are registered in the registered word dictionary TOURO.
It shall be stored in KU.

FIG. 39 is a detailed flowchart of the conversion prohibited word registration process (step S38-3) in this embodiment.

Step S39-1 is notation / reading input processing. In this process, the screen of FIG. 31 is displayed, and the operator is prompted to input the notation and reading of the word to be made into the conversion prohibited word.

Step S39-2 is a kana-kanji conversion dictionary search process. Based on the information input in step S39-1, the Kana-Kanji conversion dictionary DIC is searched. Since the kana-kanji conversion dictionary is sorted in the order of reading the words, first, the pronunciation is used as a key to search. When there is a word with the same reading, the notation is further compared. If there is a word that matches the reading, it is assumed that the corresponding word exists. As a result of the search, step S
According to 39-3, when the corresponding word exists, the process branches to step S39-4, and when it does not exist, there is no word that should be the conversion prohibited word, so the conversion prohibited word registration process ends.

Step S39-4 is a conversion prohibited word registration confirmation process. In this process, the screen of FIG. 32 is displayed and the operator is asked to confirm the registration. On this screen, the information possessed by the word retrieved in step S39-2 is displayed. Therefore, in addition to the information input in step S39-1, information on the part of speech and frequency is also displayed. The operator looks at this and inputs a yes key or no key. Depending on the entered key, step S
According to 39-5, the word deletion processing is ended, or the process branches to step S39-6.

Step S39-6 is a conversion prohibited word registration process. In this process, step S39-2
The word retrieved from the kana-kanji conversion dictionary DIC in is added to the conversion prohibited word dictionary NOTCNV. The addition means the following processing, but it is a processing that is generally widely performed and is well known, so a detailed description thereof will be omitted.

A position to be added in the dictionary, that is, an address is detected according to the format of the conversion prohibited word dictionary.

Data of all the words existing after the above address are transferred backward to the memory by the data size of the word to be added.

The data of the word to be added is transferred to the area after the above address in the memory. When this process ends, the word deletion process ends.

FIG. 40 is a detailed flowchart of the conversion prohibited word deleting process (step S38-4) in this embodiment.

Step S40-1 is a conversion prohibited word list display process in this embodiment. In this process, the screen of FIG. 33 is displayed. The screen of FIG. 33 is an example in which registered conversion prohibited words are displayed in a list.
Next, in step S40-2, a key is pressed from the keyboard and an interrupt is awaited. When the end key is input, the conversion prohibited word deletion process ends. If the delete key is input, the process branches to step S40-4, and if any other key is input, the process branches to step S40-5.

Step S40-4 is a conversion prohibited word deletion process. In this process, step S40-2
The conversion-prohibited word indicated by the cursor when the delete key is input in step (3) is deleted from the conversion-prohibited word dictionary NOTCNV. To delete means to fill the area of the corresponding word from the conversion prohibited word dictionary and to transfer the words after the next existing word to the memory, but this is not known because it is well known in the general processing. . When this process ends, the process advances to step S40-1 again. In step S40-1, the screen resulting from the deletion is displayed as shown in FIG.

Step S40-5 is a process for inputting a key other than the above, is a process for the cursor moving key and the screen moving key, and is a process generally performed in a character processing device of the same type. Since it is known, it will not be described in particular.

FIG. 41 is a detailed flowchart of the kana-kanji conversion processing (step S38-5) in this embodiment. Since this processing procedure is the same as the kana-kanji conversion processing procedure of the first embodiment described with reference to FIG. 14, the description will be omitted.

As described above, according to this embodiment,
Even if a word exists in the Kana-Kanji conversion dictionary, if a word with the same information as that exists in the conversion-prohibited word dictionary, the word registered as a conversion-prohibited word is converted if the word is not converted to Kana-Kanji. By deleting from the prohibited word dictionary, it is possible to return to the state where kana-kanji conversion is possible. At this time, the characteristic part stored in the kana-kanji conversion dictionary can be restored and made effective.

Further, in the present embodiment, the deletion from the conversion prohibited word dictionary can be realized by designating on the list display of the conversion prohibited words. Therefore, the operator looks over the conversion prohibited words and finds which word It is possible to check whether the word is a conversion prohibited word and return the necessary word to a convertible word.

Further, the instruction operation of the word for releasing the inhibition of the conversion becomes easier than the case of manually inputting the information of the word.

(Other Embodiments) In the third embodiment, as in the first embodiment, it is assumed that the conversion prohibited word dictionary is provided.
As described above, an area for storing an address in the dictionary for converting kana-kanji of the conversion prohibited word may be provided. In that case, the list of conversion prohibited words displays the contents of the kana-kanji conversion dictionary corresponding to all the stored addresses.

Further, the function of realizing the prohibition cancellation by displaying the list of the conversion prohibited words in the third embodiment and instructing the cancellation of the prohibition on the display, and the word registration instruction explained in the first and second embodiments. If the designated word is a conversion prohibited word when there is, a function for canceling the prohibition can be used together.

Further, in the first and second embodiments, the registration and deletion of words are performed by inputting the reading and the notation on the dedicated input screen. However, it is possible to execute these processes even while the document is being edited. In this case, the notation part may be able to capture a character string in the document by designating.

Although each of the above embodiments has been described as a single device, this embodiment is also applicable to a system including a plurality of devices and can be realized by supplying a program to the devices. It goes without saying that it is also possible.

[0165]

As described above, according to the present invention,
It is determined whether the information about the word for which registration is instructed is stored in the conversion prohibited word memory, and if stored, the word is restored as the conversion target. It is possible to set a word as a conversion target without being aware of whether it is a word that is not in the dictionary or a word that is in the dictionary but conversion is prohibited.
In particular, in the case of a word whose conversion is prohibited, the information before the prohibition of conversion can be reused.

Further, it is determined whether the word instructed to be deleted is stored in the registered word storage unit or in the word dictionary, and if it is stored in the registered word storage unit, the word is deleted from that word dictionary. If it is stored in, the conversion prohibition word storage unit stores it so that it is excluded from the conversion target without being aware of where the word you want to exclude from the conversion target is stored. can do.
