Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention is a kanji system that converts a kana character string input from a keyboard into a desired kanji-kana mixed sentence by searching a kana-kanji conversion dictionary in a storage device based on the reading. This invention relates to a kana-containing sentence input device.

[Conventional technology]

Traditionally, a kana character string is input on the keyboard, and then when a specific key, for example a conversion key, is pressed, the kana character string input up to that point is used as the reading, and the kana character string in the storage device is converted into a kanji-kana mixture. Search a kana-kanji dictionary to convert it to a string,
There is a device that converts the kanji into kanji and creates sentences containing kanji and kana. Generally, there are a plurality of homophones (conversion candidates) whose reading is one kana character string, and it is necessary to select and instruct a desired word from among the conversion candidates. Therefore, in the so-called successive conversion method, in which the inputter looks at the display screen every time a conversion is instructed and confirms whether it is the desired kanji, the inputter is forced to interrupt his or her thinking and is forced to read the original. When continuously inputting text based on the original text, there is a drawback that the user must interrupt the operation because the user's line of sight must alternate between the original and the display screen.

The invention described in Japanese Patent Application Laid-Open No. 58-56068 is
To solve this problem, in the input mode, the input reading string is memorized as is without converting it to kana-kanji, and in the correction mode, a specified range of the reading string is specified and the document is converted to kana-kanji. We are proposing an editing device. However, this document editing device is cumbersome to operate because it requires specifying the first and last characters of the reading character string to be converted into kana-kanji, and what to do when an error in the input reading characters is discovered in the correction mode. No method has been proposed.

In addition, the invention described in Japanese Patent Application Laid-open No. 57-132272 proposes a character processing device that retains a reading character string even after the kana-kanji conversion process and can continue to use this reading character string. There is. However, no concrete proposals have been made regarding the order in which this character string should be extracted, how it should be processed (corrected, added or deleted), and how it should be converted into kana-kanji.

[Problems to be Solved by the Invention] With the above-mentioned conventional device, it is troublesome to operate the reading character string during the kana-kanji conversion process, and it is not possible to correct or add or delete the target reading character string, so it is difficult to input. The degree of freedom in the conversion process is limited, and the confirmation process operation is performed every time a selection is made, making it difficult to improve operability.

SUMMARY OF THE INVENTION An object of the present invention is to solve the drawbacks of the conventional devices and to propose a character input device containing kanji and characters that has good operability during kana-kanji conversion processing and a high degree of freedom in conversion processing.

[Means to solve the problem]

The purpose is to provide a kana character input key, a sequential selection input mode in which kana-kanji conversion is performed while confirming conversion candidates one by one, and a batch selection method in which kana-kanji conversion candidates are confirmed after inputting a predetermined amount of kana-kanji mixed sentences. a keyboard having an input mode switching key for switching the input mode, a switching key for switching between batch input and batch selection in the batch selection method, and a reading character string for storing the reading character string input by the kana character input key. a memory, an input mode switching control unit, a kana-kanji conversion processing unit, a kana-kanji conversion dictionary, a reading save memory for saving the memory contents stored in the reading character memory, and the kana-kanji conversion dictionary. a document memory for storing conversion candidates created by the kana-kanji conversion processing unit; a temporary conversion character string document position memory for storing the storage position of the conversion candidates in the document memory; a provisional conversion candidate control unit that controls to store the converted kana-kanji character strings in the reading save memory and provisional converted character string position memory in the document; a reading character string restoring means for restoring the reading character string to the reading character memory; a re-kana-kanji conversion means for converting the reading character string restored to the reading character memory into kana-kanji again;
a display device for displaying input kana characters and character strings resulting from kana-kanji conversion in sequential and batch input; and a yomi for causing the yomi string restoring means to restore yomi character strings to the yomi character memory in order from the beginning of the yomi save memory. a character string restoration control means; a provisional kana-kanji conversion reading character string correction means for displaying the temporary kana-kanji conversion reading character string restored in the reading character memory on the display device and correcting and adding/deleting it by the successive conversion method; A temporary character string memory that temporarily stores the character string corrected by the provisional kana-kanji conversion reading character string correction means, and the conversion candidates stored in the document memory are temporarily stored in this temporary character string memory. means for replacing the character string that has been converted and storing it in the document memory as a finalized character string; and collective confirmation means for determining the provisional converted character strings all at once when all of the provisional converted character strings are the desired character strings. This is achieved by providing

[Effect]

During batch input using the batch selection method, provisional kana-kanji converted reading character strings corresponding to kanji that have been provisionally converted to kana-kanji are stored in the reading save memory, and when selected, they are returned to the reading character memory in order from the beginning. It makes it possible to change conversion candidates, correct reading character strings, and add/delete them, and further, when all of the provisional kana-kanji conversion character strings are the desired kanji, it is possible to confirm them all at once. .

〔Example〕

Hereinafter, one embodiment of the structure of the present invention will be described in detail with reference to FIGS. 1 to 4.

FIG. 1 is a block diagram showing the circuit configuration of a kanji/kana mixed sentence input device according to the present invention. In the figure, 1 is the keyboard, 2 is the input key register where one key code input from keyboard 1 is set, and 3 is the input mode control unit, which is either sequential selection method or batch selection method. manage the
This controls the timing of kana-kanji conversion. This input mode is designated by the operator at any time by pressing an input mode key provided on the keyboard. 4 is a reading character memory that stores input kana character strings for each conversion unit; 5 is a conversion/non-conversion control unit that converts the contents of the reading character memory 4 from kana to kanji according to instructions from the input mode control unit 3; 6 is a kana-kanji conversion processing unit that searches the kana-kanji conversion dictionary 7 and creates conversion candidates.
What is stored in the conversion candidate memory 8? 9 is a document memory that stores the kanji-kana mixed sentences created above; 10 is a provisional conversion candidate control unit that stores information input during batch input using the batch selection method. The contents of the reading character memory 4 are read and set in the save memory 11, and the position where the first conversion candidate set in the conversion candidate memory 8 is stored in the document memory 9 is set in the temporary converted character string document position memory 12. thing,
Reference numeral 13 denotes a reading character string restoration control unit which extracts the corresponding reading character string from the reading save memory 11 and sets it in the reading character memory 4 during batch selection using the batch selection method; 14 represents a temporary character string memory; 15 is a reading display register, 16 is a temporary character string display register, and 17 is a document display register, which temporarily stores changed conversion candidates, and the contents of reading character memory 4, temporary character string memory 14, and character memory 9, respectively. is set as display data, and 18 is read by the display control unit and is set in display register 1.
5. It controls displaying the contents of the temporary character string display register 16 and document display register 17 on the display screen 19.

Next, the creation of sentences containing kanji and kana using the apparatus of the present invention will be explained.

FIG. 2 shows the flow of kana-kanji conversion input using the sequential selection method. Key data input from the keyboard 1 is stored in an input key register 2, and control is determined depending on the contents of the input key. When a character key is input, the input characters are read and sequentially stored in the character memory 4, and the next key input is accepted. Then, when the conversion key is input, the kana-kanji conversion dictionary 7 is searched and converted into a character string containing kanji and kana according to the contents of the reading character memory 4 that have been stored up to that point.

Here, the conversion results including the homophones are set in the conversion candidate memory 8, and the first conversion candidate is temporarily stored in the document memory 9. The inputter confirms this on the display screen 19, and if the conversion candidate is the desired one, inputs the next reading character to store the conversion candidate in the document memory 9 as a confirmed character string containing kanji and kana. After that, the input of the corresponding reading character is continuously accepted.

If the conversion candidate is not the desired character string containing kanji and kana, there are the following two control methods.

(1) When the pronunciation character string is incorrect When the no-conversion key is input, the provisional conversion character string is deleted from the document memory 9 and the conversion candidate memory 8 is also cleared. Then, the user returns to the reading character input state, deletes the incorrect reading character by, for example, using the backward key, and then inputs the correct reading character string again.

(2) When a different homophone is desired, the temporary conversion character string is changed to the second or subsequent conversion candidate by inputting the conversion key again. Note that if the desired character string is not converted into the desired kanji-kana character string, this is because the corresponding word is not registered in the kana-kanji dictionary, and the reading character string cannot be converted by inputting the non-conversion key as described in the previous section. The desired kanji and kana mixed sentences are obtained by subdividing and converting each kanji character at a time.

On the other hand, when there is no need to convert kana to kanji and the input kana characters are used as they are, the contents of the reading character memory 4 are determined as they are and stored in the document memory 9 by inputting the no-conversion key.

As described above, the sequential selection method is sufficiently easy to use for beginner input users, and is a reliable input means that does not overlook erroneous input or conversion.

Next, the batch input and batch selection of kana-kanji conversion input using the batch selection method will be explained with reference to FIGS. 3 and 4.

During batch input, as shown in FIG. The kanji conversion dictionary 7 is searched and converted into a character string containing kanji and kana, and the first conversion candidate at that time is stored in the document memory 9 as a provisional conversion character string, and the position information of the provisional conversion character string in the document memory 9 is stored. is stored in the temporary converted character string document position memory 12, and the next reading input is accepted.

On the other hand, if the non-conversion key is input, the contents of the reading character memory 4 are stored as they are in the document memory 9 as a fixed character string.

Also, after a suitable amount of reading characters are input continuously,
When the end key is input, control shifts to the batch selection method.

At the time of batch selection, as shown in FIG. 4, the reading is restored to the reading character memory 4 from the beginning of the reading save memory 11, and the temporary converted character string is extracted by the temporary converted character string document position memory 12. When the inputter confirms the provisional converted character string on the display screen 19 and recognizes that it has been correctly converted to the desired kanji/kana character string, presses the confirm key to confirm the provisional converted character string. Store it in the document memory 9 as a character string,
The corresponding reading save memory 11 and temporary converted character string document position memory 12 are cleared, and the process moves to confirmation of the next temporary converted character string.

At this time, the conversion candidate memory 8 is a memory that temporarily stores conversion candidates for the reading character memory 4, and at the time of batch selection, it stores conversion candidates for a new reading. Therefore, the contents from the time of batch input to the time of batch selection are not stored or retained. In addition, for the kana-kanji character string whose reading has been restored from the reading save memory 11 to the reading character memory 4, the reading stored in the reading save memory 11 and the position of the provisionally converted character string in the document memory 9 are temporarily converted. It can be obtained by storing the character strings in correspondence with each other in the character string document position memory 12.

Here, if it is not the desired kana-kanji character string, it is sufficient to return to the reading state by pressing the correction key, correct the reading, and input a new reading by the sequential selection method.

Therefore, in this case, the kana-kanji conversion dictionary will be searched again.

On the other hand, if it is not the desired kanji-kana mixed sentence, the contents of the reading character memory 4 are displayed on the display screen 19 by pressing the correction key, and then other conversion candidates are selected in exactly the same way as the sequential selection method. Control then moves to selection or correction of reading characters. The converted character strings at this time are all stored in the primary character string memory 14, and when the confirm key is pressed, the provisional converted character string and the contents of the primary character string memory 14 are replaced and stored in the document memory 9 as a confirmed character string. Therefore, the temporary character string can be created without being restricted by batch input using the batch selection method, so it is possible not only to change conversion candidates or correct the reading character string, but also to add and delete words. After the character string is determined, the corresponding reading save memory 11 and provisional converted character string document position memory 12 are cleared, and the process moves on to confirming the next provisional converted character string. When the number of characters increases or decreases using the above method, the memory location information is increased or decreased by the number of characters that have changed and is used as new memory location information to create the desired sentence containing kana and kanji. can be created.

When there are no more provisional conversion character strings, control is returned to batch input using the batch selection method, and new input is accepted.

In addition, when all the temporarily converted character strings are visually checked on the display screen 19 and all have been converted to the desired character strings containing kanji and kana, the end key is input to convert all the temporarily converted character strings to the desired character strings. stores the provisional converted character string in the document memory 9 as a finalized character string,
The reading save memory 11 and the temporary converted character string document position memory 12 are all cleared and control is returned from batch selection to batch input in the batch selection method.

Although not specifically explained above, the kanji-kana-containing sentence input device according to the present invention is equipped with an input mode key, and the sequential selection method or batch selection method can be specified by the inputter's instructions. It can be freely selected, and the input mode control section 3 manages the control.

〔Effect of the invention〕

As described above, the present invention sequentially stores provisional kana-kanji converted reading strings that have been temporarily converted into kana-kanji characters during batch input using the batch selection method, starting from the beginning of the reading save memory that stores the provisional kana-kanji converted reading strings. Since it can be restored to the reading character memory, the restoration operation is easy, and it is also possible to change the conversion candidates of the restored provisional kana-kanji conversion reading character string, correct the reading character string, and add or delete the input character string. The degree of freedom in the conversion process is increased, and furthermore, if all the provisional converted character strings match the desired kanji/kana mixed character string, they can be finalized all at once, making it easier for inputters to perform operations. can be simplified.
