[Detailed description of the invention]

INDUSTRIAL APPLICATION FIELD The present invention relates to a Roman character input device used in the field of Japanese information processing. Configuration of conventional examples and their problems In recent years, many Romaji input devices have been developed in the field of Japanese information processing as means for easily inputting Japanese pronunciations. A conventional Roman character input device will be explained below. Figure 1 shows a block diagram of a conventional Roman character input device, in which 1 is a Roman character input section for inputting Roman characters indicating the Japanese pronunciation, and 2 is a Roman character input section that temporarily stores the Roman character string input from the Roman character input section 1. An input Roman character string temporary storage section 3 is an input Roman character string final valid point temporary storage section that stores the final valid point in the input Roman character string temporary storage section 2 of the Roman character string temporarily stored in the input Roman character string temporary storage section 2; reads the Roman character string temporarily stored in the input Roman character string temporary storage unit 2 up to the final valid point of the input Roman character string, which is the final valid point temporarily stored in the temporary storage unit 3, and outputs the Kana string corresponding to this Roman character string. 5 is a conversion string temporary storage section that temporarily stores the kana string output from the Romaji-kana converter 4; 6 is a deletion input section into which a deletion signal is input; 7 is an input when a deletion signal is received from the deletion input section 6; a deletion control unit that reads the value of the final point temporarily stored in the Roman character string final valid point temporary storage unit 3, subtracts 1 from this value and stores it in the input Roman character string final valid point temporary storage unit 3;
Reference numeral 8 denotes a display section for outputting and displaying the kana string temporarily stored in the converted kana string temporary storage section 5. The operation of the conventional Roman character input device configured as described above will be explained below.

[Table] Table 1 shows the status of each part of the conventional Roman character input device when inputting the Roman character string corresponding to the kana string "Riyoshiyuushiyo" into the conventional Roman character input device. Column A is the processing Column B shows the input from the Roman character input section 1 or deletion input section 6, Column C shows the valid Roman character string temporarily stored in the input Roman character string temporary storage section 2, and Column D shows the input Roman character string. The value of the final valid point temporarily stored in the final valid point temporary storage section 3 is shown, and column E shows the kana column temporarily stored in the converted kana column temporary storage section 5. First, with process number 1, from Roman character input section 1 to column B.
Enter the Roman alphabet "R" as shown in the figure. The input Roman character string temporary storage section 2 temporarily stores the Roman character "R" as shown in column C, and the value of the input Roman character string final valid point temporary storage section 3 becomes "0" as shown in column D. Since the Roman character "R" cannot be converted to kana, there is no kana to be temporarily stored in the conversion kana column temporary storage section 5, as shown in column E. Next, as shown in process number 2 and process number 3, when the Roman characters "R" and "Y" are input in sequence, the Roman character string "RYO" is stored in the input Roman character string temporary storage unit 2 as shown in column C of process number 3. is temporarily stored.
This Romaji string is converted into a kana string by the Romaji-kana conversion section 4, and the kana string "Riyo" is temporarily stored in the converted kana string temporary storage section 5 as shown in column E of processing number 3. Furthermore, the Roman characters "USYUU" are input in sequence from process number 4 to process number 8.
As shown in column C of processing number 8, when the Roman character string "RYOUSYUU" is temporarily stored in the input Roman character string temporary storage unit 2, this Roman character string and the Roman character kana conversion unit 4 convert it to kana, and the converted kana string is temporarily stored. In section 5, the kana string "RIYOSHIYU" is outputted from Romaji-kana conversion section 4 and stored as shown in column E of processing number 8. Next, in order to input the Roman character string "SHO" corresponding to the kana "Shiyo", input of Roman characters is started from processing number 9. As shown in column B of process numbers 9 and 10, input the Roman letters "S" and "H" in sequence. Next, assume that the Roman letter "O" should have been input in process number 11, but in process number 11, the Roman letter "H" was incorrectly input as shown in column B of process number 11. Next, in process number 12, the Roman character "O" is input, and the input of the Roman character string "SHO" indicating the kana character string "Shiyo" is completed. However, in reality, as mentioned above, the Roman character string "SHHO" was input in processing numbers 9 to 12, and when the Roman character input in processing number 12 was completed, it was temporarily stored in the input Roman character string temporary storage unit 2. The Roman character string is "RYOUSHUSHHO" as shown in column C of process number 12. This Romaji string is converted into a Romaji-Kana string by the Romaji-Kana conversion unit 4,
Since the Roman character string "SHHO" cannot be converted to kana, the Roman character string converted into kana by the Roman character-kana converter 4 for the Roman character string temporarily stored in the input Roman character string temporary storage section 2 shown in column C of processing number 12 is processing number 12. As shown in column E, the result is ``riyoshiyu'', and the kana string ``shiyo'' cannot be obtained as a result of Romaji-kana conversion. The user looks at the kana string output and displayed on the display section 8 and learns that the input of the Roman character string corresponding to the kana string "Shiyo" has failed, and presses the deletion input section 6 to delete and correct the input Roman character string. With more removed signals,
Input as shown in column B of process 13. When the deletion control unit 7 receives the deletion signal, it reads the final valid point value “11” temporarily stored in the input Roman character string final valid point temporary storage unit 3 as shown in column D of processing number 13, and sets it to “1”. This value is subtracted to "10", and this value is stored in the input Roman character string final valid point temporary storage unit 3 as shown in column D of process number 13. The user cannot directly view the Romaji string temporarily stored in the input Romaji string temporary storage section 2, but can only estimate the input Romaji string from the Romaji-Kana conversion result temporarily stored in the converted Kana string temporary storage section 5. Can not. For this reason, completely deleting the incorrectly input Roman character string is the conversion kana string temporary storage unit 5.
It can be seen from the Kana string temporarily stored in , that the Kana "U" corresponding to the final Roman character "U" of the correctly input Roman character string was deleted as a result of the deletion of the input Roman character string. At the time when the delete key is pressed in process number B, there is no change in the conversion column as shown in column E of process number 13, so the user assumes that erroneous input still remains. Next, as shown in processing numbers 14 to 16, deletion request signals are inputted sequentially from the deletion input section 6, and as shown in column C of processing number 16, the correct Roman character string "RYOUSYUU" is inputted in the Roman character string temporary storage section 2.
get to. The conversion result of this Roman string is processing number 16
As shown in column E, it becomes "Riyoshiyuu",
It is no different from the conversion sequence in process number 12, where I noticed an incorrect input of a Roman character string. Therefore, the user further inputs a deletion signal from the deletion input unit 6 as shown in column B of process number 17. When the deletion control unit 7 receives the deletion signal from the deletion input unit, it reads the final valid point value “7” temporarily stored in the input Roman character string final valid point temporary storage unit 3, subtracts “1”, and makes it “6”. As shown in column D of process number 17, the input Roman character string is stored in the final valid point temporary storage section 3. The Romaji-kana conversion unit 4 reads the Romaji string temporarily stored in the input Romaji string temporary storage unit 2 up to the final valid point value “6” temporarily stored in the input Romaji string final valid point temporary storage unit 3, and converts this Romaji string to The kana string "RIYOSHIYU" corresponding to the string is output to the converted kana string temporary storage section 5 as shown in column E of process number 17. As a result of the user's deletion input in column B of process number 17, the kana string "RIYOSHIYU" is the result of Romaji-kana conversion of the input Romaji string shown in column E of process number 16.
has become the kana column "Riyoshiyu" shown in column E of process number 17, so the process number has changed from process number 9 to process number 9.
I learned that I had finished deleting the incorrect input of the Roman character string corresponding to the kana string "shiyo" shown in 12. Now that the incorrect input has been removed, the user can enter the transaction number
Sequentially romanized "USHO" as shown from 18 to 21
is input from the Roman character input section 1, and the desired kana string ``Riyoshiyuushiyo'' is obtained as shown in column E of process number 21. As described above, conventional Roman character input devices perform Roman character input processing. However, in the above configuration, when deleting an input Roman character string, one character from the rear of the input Roman character string is deleted. 1 to the Roman character string before the Roman character string
The problem was that the Roman character string could not be deleted unless the characters were deleted one by one, resulting in poor operability. OBJECT OF THE INVENTION The present invention solves the above-mentioned conventional problems.
An object of the present invention is to provide a Roman character input device that, when deleting an input Roman character string, can delete at once from the input Roman character string an input Roman character substring corresponding to the last kana of a kana string corresponding to the input Roman character string. shall be.

[Table] Table 2 shows the status of each part of the Roman character input device of this embodiment when inputting the Roman character string “RYOUSYUUSHO” corresponding to the kana string “RIYOUSYUUSHO” into the Roman character input device of this example. is a diagram,
Column F indicates the processing number, and column G indicates the Roman character input section 9.
or the input from the deletion input unit 15, column H indicates the Roman character string temporarily stored in the input Roman character string temporary storage unit 10, and column I shows the input Roman character string temporarily stored in the final valid point temporary storage unit 11. The value of the final valid point is shown, column J shows the kana string temporarily stored in the converted kana string temporary storage section 17, column K shows the romaji interpretation table temporarily stored in the romaji interpretation table temporary storage section 13, Column L indicates the final valid point value in the Roman character interpretation table temporary storage section 13 of the Roman character interpretation table temporarily stored in the interpretation table final point temporary storage section 14. First, as shown in column G of the row indicated by processing number 1 in column F, the Roman character "R" is input from the Roman character input section 9.
is input. The input Roman character string temporary storage unit 10 temporarily stores the Roman character “R” as shown in column H of process number 1, and the value in the input Roman character string final valid point temporary storage unit 11 is stored in column I of process number 1. It becomes "O" as shown. Romaji "R" 1
Since it cannot be converted into Kana characters, nothing is stored in the conversion Kana column temporary storage section 17, and there is no content in the interpretation table temporary storage section 13. Since nothing is stored in the Roman character interpretation table temporary storage section 13, the value of the interpretation table final point temporary storage section 14 is "-1" as shown in column L of process number 1.
It is becoming. Next, as shown in column G of processing numbers 2 and 3, when the Roman letters "Y" and "O" are input sequentially from the Roman character input section 9, the input Roman character string temporary storage section 10 is inputted as shown in column H of processing number 3. The Roman character string "RYO" is temporarily stored in the . The Romaji-Kana conversion unit 12 reads the input Romaji string "RYO", outputs the Kana string "RIYO" corresponding to this Romaji string, and also converts the input Romaji string "RYO" corresponding to this Kana string "RIYO" into the input Romaji string. Information “O” regarding the position temporarily stored in the temporary storage unit 10 is transmitted to the Roman character interpretation table temporary storage unit 13. The interpretation table final point temporary storage unit 14 adds “1” to the final point value in the Roman character interpretation table temporary storage unit 13 of the temporarily stored Roman character interpretation table to make it “0”, and adds it to the column L of processing number 3. Store the value "0" as shown. Next, as shown in column G of processing number 4, when the Roman character "U" is input from the Roman character input section 9, the Roman character string "RYOU" is temporarily stored in the input Roman character string temporary storage section 10 as shown in column H of processing number 4. be remembered. Input Roman character string final valid point temporary storage section 1
0 adds "1" to the temporarily stored final valid point value of the input Roman character string and sets it to "4" as shown in column I of processing number 4. The Romaji-kana conversion unit 12 reads the input Romaji string from the input Romaji string temporary storage unit 10 up to the final valid point “4” of the input Romaji string temporarily stored in the input Romaji string final valid point temporary storage unit 11, and converts the input Romaji string to correspond to the Romaji string. In addition to outputting the simple kana string "Riyou", the position information "3" in the input Roman character string temporary storage unit 10 of the Roman character "U" corresponding to the newly converted kana "U" is temporarily stored in the Roman character interpretation table. 13. The Romaji interpretation table temporary storage section 13 additionally stores the position information "3" transmitted from the Romaji-Kana conversion section 12 as shown in column K of process number 4. The interpretation table final point temporary storage section 14 stores the temporarily stored interpretation table final point value as "1" as shown in column L of process number 4 since the Romanization table has been added to the Romanization table temporary storage section 13. do. Below, as mentioned above, the Roman character string "RYOU"
In the same way as input processing, input the Roman character string "SYUU" sequentially as shown in processing numbers 5 to 8, and input the Roman character string "SYUU" in the Roman character interpretation table temporary storage section 1.
3, the Roman character interpretation table "0, 3, 4, 7" is temporarily stored as shown in column K of processing number 8, and the interpretation table final point value temporarily stored in the interpretation table final point temporary storage section 14 is processed. Assume that the number becomes "3" as shown in column L of number 8. Next, a process is performed to input the Roman character string ``SHO'', which corresponds to the kana ``Shiyo''. First, as shown in processing number 9 and processing number 10, the Roman letters "S" and "H"
are input sequentially from the Roman character input section 9. Processing number
As shown in column J of 10, the Roman character string "SH" cannot be converted to kana, so the converted kana string temporary storage section 17
There is no change in the kana column temporarily stored in the column J from the time shown in column J of process number 8. Next, in process number 11, the Roman character "O" should be input from the Roman character input section 9, but suppose that the Roman character "H" is input by mistake. Next, at process number 12, enter the Roman character "D" from the Roman character input section 9 and enter the kana string "Shiyo".
Finish inputting the Roman character string corresponding to . After inputting the Roman character "O" from the Roman character input section 9 as shown in column G of processing number 12, the Roman character string "RYOUSYUUSHHO" is temporarily stored in the input Roman character string temporary storage section 10 as shown in column H of processing number 12. be remembered. The input Roman character string final valid point value temporarily stored in the input Roman character string final valid point temporary storage unit 11 is the column I of processing number 12.
It becomes "11" as shown in . The Romaji-kana conversion unit 12 reads the input Romaji string from the input Romaji string temporary storage unit 10 up to the final valid point of the input Romaji string that is temporarily stored in the input Romaji string final valid point temporary storage unit 11 and determines whether it corresponds to this Romaji string. However, the Roman character string "SHHO" after the input Roman character string cannot be converted to kana, and it can only be obtained by converting the same as the case shown by column J in process number 8 or the Y column, so do not operate. Interrupt. The user checks the kana string temporarily stored in the converted kana string temporary storage section 17 on the display section 18 and learns that the Roman character string corresponding to the kana "shiyo" was input incorrectly. To correct incorrect input, the user must delete input section 1.
Enter the deletion request from step 5. When the deletion control unit 16 receives a deletion request from the deletion input unit 15, it reads the interpretation table final point value from the interpretation table final point temporary storage unit 14, and stores the data in the Roman character interpretation table temporary storage unit 13 that is pointed to by this interpretation table final point value. Read the value "7" of the Roman character interpretation table, subtract "1" from the value "7" of this Roman character interpretation table to get "6", input this value "6" to the Roman character string final valid point temporary storage section 11 Store as shown in column I of process number 13. As a result, the input Roman character string temporarily stored in the input Roman character string temporary storage section 10 becomes "RYOSYU" as shown in column H of processing number 13. Next, the deletion control unit 16 subtracts 1 from the interpretation table final point value “3” temporarily stored in the interpretation table final point temporary storage unit 14 to make it “2”, and stores it in the interpretation table final point temporary storage. 14. Next, the Romaji-kana conversion unit 12 reads the input Romaji string from the input Romaji string temporary storage unit 10 up to the input Romaji string final valid point value “6” temporarily stored in the input Romaji string final valid point temporary storage unit 11, and Kana string temporary storage unit 1 that converts the kana string “Riyoshiyu” corresponding to the Roman character string
At the same time, the Roman character interpretation table is transmitted to the Roman character interpretation table temporary storage section 13. As shown in column G of process number 13, input Roman letters can be deleted by inputting the deletion signal only once from the deletion input section 15, whereas in the conventional example, the deletion signal had to be input five times in succession. Processing ends. Next, as shown in processing numbers 14 to 17, the Roman character string "USHO" is inputted sequentially from the Roman character input section 9, and the desired character string is inputted into the conversion kana string temporary storage section 17 as shown in column J of processing number 17. Get the column ``Riyoshiyuushiyo''. As described above, according to this embodiment, the Romaji-Kana conversion unit 12 outputs the Romaji interpretation table during Romaji-Kana conversion, and the Romaji interpretation table temporary storage unit 13 temporarily stores the Romaji interpretation table output from the Romaji-Kana conversion unit 12. and an interpretation table final point temporary storage section 14 that temporarily stores the final point in the Romanization table temporary storage section 13 of the Romanization table, and upon receiving the deletion signal, the interpretation table point value is stored from the interpretation table final point temporary storage section 14. Read the Roman character interpretation table value corresponding to the final point value of this interpretation table from the Roman character interpretation table temporary storage section 13, and input the value obtained by subtracting "1" from this Roman character string interpretation table value to the Roman character string final valid point temporary storage section 11. By providing a storage deletion control section 15, when deleting an input Roman character string, the input Roman character substring corresponding to the final kana of the Kana string corresponding to the input Roman character string can be deleted at once from the input Roman character string. Effects of the Invention The Roman character input device of the present invention includes a Roman character input section, an input Roman character string temporary storage section, an input Roman character string final valid point temporary storage section, a Roman character kana conversion section,
