Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial application] The present invention relates to a kana-kanji conversion device, and particularly to an operation for returning a character string once converted to a kanji-kana mixed sentence to the original reading, and the returned reading. The present invention relates to a kana-kanji conversion device that has a means such that the backward function of can be realized with one key.

[Conventional technology]

Conventionally, several methods are known in which the conversion result once obtained is returned to the state before conversion (reading state) and re-converted. One of them is disclosed in Japanese Patent Laid-Open No. 60-205662 / Kana Kanji. There is a method described in "Conversion method".
The method shown here is to move the cursor etc. to the character string of the conversion result and instruct re-conversion, so that the character string of the phrase or phrase including the position of the cursor is returned to the reading. It was Furthermore, erase one character at the end of the above reading,
That is, when backspace is performed, in addition to the above operation, for example, it is necessary to hit the backspace key.

These operations impose a heavy burden on the operator in the following cases, for example. That is, if the punctuation mark is not defined as a single phrase, the sentence is read and input, and the punctuation mark (that is,
Suppose that at the moment when you type "."), You realize that you have made an error typing the phrase. In the conventional operation, two operations, that is, an operation of returning a phrase including a punctuation to reading and an operation of erasing the punctuation, had to be performed.

[Problems that the invention is trying to solve]

In the kana-kanji conversion method according to the conventional technique, the present invention provides a means for realizing one-touch operation of returning the converted part to reading and erasing one character at the end of the returned reading (backspace operation). It is to provide a kana-kanji conversion device.

[Means for solving problems]

When the backspace key (also referred to as the backward key) is pressed immediately after the cursor that is immediately after the phrase that has been converted from the input reading and the correspondence with the reading has been maintained (hereafter called the unestablished phrase) The kana-kanji conversion device according to the present invention first, if the phrase immediately before the cursor is an unestablished phrase, returns the unestablished phrase to the corresponding reading, and then returns the last character of the returned reading. The removed character string is displayed on the display device instead of the unestablished character string.

[Action]

By doing this, for example, in Kana-Kanji conversion where conversion is performed each time you input a reading, if you notice an input error while inputting the reading, just press the backspace key immediately It is possible to return the phrase that has been read to the reading and also erase the last character of the reading.

Two functions, a function to return the unestablished phrase to reading by typing the space key immediately after the unestablished phrase, and a backspace function to erase one character string immediately before the cursor and move the cursor to the erased character position. The present invention is realized by continuously executing.

Example of Invention

 An embodiment of the present invention will be described below.

FIG. 2 is a block diagram showing the configuration of the kana-kanji conversion device of the present invention. In FIG. 2, the processing unit 201 is, for example, a microprocessor, and the program memory 20.
The program stored in 3 is executed, and each block is controlled and data is transferred via the pass line 202.

When a key code for instructing a character or control is input from the key input device 208 which is a part of the data input device, the key code is stored in the key code memory 207. If the input code represents a character, the processing device 201 causes the pattern generation device 209 to generate a pattern of the input character and displays it on the display device 211 through the display control circuit 210. The kana-kanji conversion device performs kana-kanji conversion as reading of kana-kanji conversion, stores the result in the display buffer 205, and simultaneously displays it on the display device 211. At that time, the readings used for performing the above Kanji conversion are stored in the reading table 206,
Even after the conversion is completed, it is stored in a form corresponding to the notation in the notation buffer 205 (in this way, when the reading and the notation are stored in a corresponding form, this character string is an unestablished character string. Called).

On the other hand, if the input code represents a control command, the processing device 201 starts each control. The present invention is characterized by the processing when the entered code is a backward key (also called a backspace key, but the name "backward key" is used in the following description).

When the entered key is the backward key, the processing device 20
1 obtains the current cursor position indicated by the cursor pointer 213, and when the current cursor position is immediately after the punctuation of the bunsetsu and the immediately preceding bunsetsu is an unestablished bunsetsu, it is stored in the notation buffer 205. Instead of the notation of the unestablished phrase, the corresponding reading is taken out from the reading table 206, one character at the end of the obtained reading is deleted and displayed on the display device 211, and the cursor control device 212 displays the cursor display position as described above. It is set immediately after the display position of the reading with one character deleted, and the cursor pointer 213 is also updated.

FIG. 1 is a flowchart of processing functions using the present kana-kanji conversion device, and the processing contents will be described below with reference to this drawing.

In the key input process (101), the key input device 20
The keys are sequentially received from 8. The processing device 201 determines whether the received key is the backward key (10
2) If it is not the backward key, the kana-kanji conversion is read and the function keys other than the backward key are processed (103). If it is the backward key, then the current cursor position is acquired and it is determined whether or not it is immediately after the break of the phrase (104). The concept of bunsetsu exists only in unestablished bunsetsu that has a correspondence between the notation and the reading. Therefore, the processing device 201 refers to the notation in the notation buffer 205 displayed immediately before the position where the cursor pointer 213 is currently pointing, the reading corresponding to the notation exists in the reading table 206, and the phrase Check if it is the end. As a result of checking whether or not the cursor is immediately after the break of the phrase (104), if it is found that the cursor is immediately after the break of the phrase, the notation that composes the phrase is matched with the notation. A reading in the reading table is obtained, and a character string in which one character at the end of the reading is deleted is displayed on the display device 211 (105).
As a result of the check of (104), if it is found that there is no break in the bunsetsu, then the character immediately before the cursor is a reading character, an unestablished character, or an established character (a character obtained by kana-kanji conversion). Although it is a string, it is determined whether or not there is no correspondence between the notation and the reading, that is, whether the reading does not exist (106). If it is reading, one character (reading) immediately before the cursor is deleted, and the cursor is displayed at the character position where the deleted reading exists (107). If it is an unestablished character string, the correspondence with the reading of the clause including the unestablished character string is stopped (that is, it is made an established character string), and the character immediately before the cursor is deleted by one character, and the deletion is performed. The cursor is moved to the designated character position (108). If it is an established character, one character before the cursor is deleted and the cursor is moved to the deleted character position (10
9). (103), (105), (107), (10
After the processes of 8) and (109), the process proceeds to the key input process (101) and the above processes are repeated.

FIG. 3 is a structural diagram showing an embodiment of the key input device 208 in FIG. From the keyboard 301, reading for performing kana-kanji conversion is input using the character keys 302. If the Kana-Kanji conversion has an automatic conversion function, it will be converted sequentially just by inputting the reading.
If not, it is necessary to press the conversion key 304 when converting to a kanji / kana mixed sentence, and to convert the text into the text as it is, it is necessary to press the non-conversion key 305. Even if it has an automatic conversion function, when a special character such as a punctuation mark, a punctuation mark, or a reading "o" appears, the conversion is automatically performed at that time. According to the present invention, when the backward key 303 is pressed, when the kana-kanji conversion is being read and input, it is immediately after the above special character appears and immediately after the conversion key is pressed to forcibly perform kana-kanji conversion. , Kana-Kanji conversion reading is not being input, the cursor is moved to the position immediately after the unestablished character string.

FIG. 4 is an embodiment showing a state displayed on the display device 211 in FIG. 2 when the present invention is carried out. In FIG. 4, a conversion character string 402 “Kana-Kanji conversion” is displayed in the text display portion of the display device 401, and a cursor 403 is displayed immediately after the conversion character string 402. In this state, as described in FIG. 3, when the conversion key is pressed immediately after the reading input of "Kanakanjihenkan" or the unestablished character string of "Kana-Kanji conversion", the cursor is moved. Occurs when. From the display state of the display device 401, the reverse key 30
When 3 is pressed, the display state of the display device 404 changes. That is, the converted character string 402 is returned to reading,
It becomes the reading character string 405, but the character string "Kana-Kanji conversion" is not returned to reading as it is, but the reading character at the end is deleted and becomes "Kana kanji henka". At that time, the cursor 406 indicates the reading character string 405.
Is displayed immediately after. That is, the role of the backward key 303 is to simultaneously perform an operation of returning an unestablished character string to reading and a normal backward (backspace) function.

FIG. 5 is an embodiment different from FIG. 4 showing a state displayed on the display device 211 in FIG. 2 when the present invention is carried out. In FIG. 5, a conversion character string 502 “Convert” is displayed on the text display portion of the display device 501, and the cursor 503 displays the conversion character string 50.
It is displayed immediately after 2. As described with reference to FIG. 3, this state occurs when the reading point "," is entered following the reading input "Henkanshi" or immediately after the unestablished character string "Convert,". Occurs when the cursor moves. When the backward key 303 is pressed from the display state of the display device 501, the display state of the display device 504 is changed. That is, the converted character string 502 is returned to the reading and becomes the reading character string 505, but the character string “converted” returns to the reading and the reading point “,” is deleted. At that time, the cursor 406 indicates the reading character string 405.
Is displayed immediately after. In this case, the reading character string 50
The reading character string 507 is added to "6" with "Reading"
You can continue the kana-kanji conversion as in “while changing”. In the above case, the cursor 50
8 is also displayed immediately after the reading character string 507.

〔The invention's effect〕

As described above, according to the present invention, it is possible to realize, with a single touch, an operation for returning a part that has undergone kana-kanji conversion to reading and an operation for deleting one character at the end of the returned reading (backspace operation).

The present invention is particularly effective in automatic conversion that does not require a conversion key, when conversion by a system such as punctuation is automatically performed, and when only punctuation is deleted and it is desired to continue reading input. Further, in the case of a system in which conversion is performed with a conversion key or the like, it is also effective when the conversion key is erroneously pressed during reading input.
