[Table] Each row of Table 1 shows the state of each part when inputting the Roman characters indicating the Japanese pronunciation "Shizengengoto" into the conventional Roman character input device, and column (A) shows the state of each part in Table 1. The row numbers are shown, column (a) shows the Roman characters input to the Roman character input section 1, column (c) shows the control code input to the control input section 3, and column (d) shows the input Roman character string storage memory. The input Romaji string stored in the Romaji conversion section 2 is shown, and the column (O) shows the Kana string output from the Romaji conversion section 4. First, when the Roman character "S" is input from the Roman character input unit 1 as shown in the first row (A) column, the character is stored and stored in the input Roman character string storage unit 2 as shown in the first row (D) column. Ru. Next, enter the Roman letters "H" and "i" in sequence as shown in the second row (A) column and the third row (A) column.
As shown in the third row (d) column, the Roman character string "SHi" indicating the Japanese pronunciation "shi" is stored and stored. Next, as shown in the 4th to 6th lines, the Roman letter "Z",
Input "E" and "N" sequentially from Roman alphabet input section 1,
A Roman character string "SHiZE" indicating the Japanese pronunciation "shize" is obtained in the input Roman character string storage unit 2. Next, in the 7th row (a) column, input the Roman letter "G" in order to input the Japanese pronunciation "ge". To indicate the Japanese reading ``ge'', it is necessary to enter the roman letter ``E'' following the roman letter ``G'', but the 8th
Assume that the user mistakenly inputs the Roman letter "H" as shown in row (A) column, and then inputs the Roman letter "E" as shown in the ninth row (A) column. The Roman character conversion unit 4 cannot interpret the Roman character string "GHE" input from the 7th line to the 9th line as a Roman character string indicating the Japanese reading, so it displays the character "G" and the Japanese reading "he". Interprets as the Roman character string "HE". Next, as shown in lines 10 to 14, the Roman character string ``NGOTO'' is expressed in the Japanese reading ``ngoto''.
Suppose that ``SHiZENGHNGOTO'' is inputted sequentially from the Roman character input section 1, and the Roman character string "SHiZENGHNGOTO" is accumulated and stored in the input Roman character string storage section 2, as shown in the 14th row (d) column. Next, in order to convert the Roman character string shown in the 14th row (D) column stored in the input Roman character string storage section 2 into a Kana column indicating the Japanese pronunciation, the control input section 3 inputs the Roman character string shown in the 15th row (U). ) Input the conversion signal as shown in the column. When the conversion signal is input to the control input section 3, the Roman character conversion section 4 reads the input Roman character string from the input Roman character string storage section 2, and searches for a Roman character string representing the Japanese pronunciation from the front of this Roman character string. , the kana indicating the pronunciation of the searched Roman character string is output as shown in the 15th row (e) column. The user's desired kana column is ``Shizengengoto'', but as shown in the 8th row (a) column, when inputting the Roman character string ``GE'' that represents the kana ``ge'', the user mistakenly enters the Roman character string ``G''. Because an extra "H" was input between the Roman character "E" and the Roman character "E", the character string "Shizen G Hengoto" shown in the 15th row (e) is obtained as the Roman character conversion result. In order to correct this character string "Shizen G Hengoto" to the desired character string "Shizen Gengoto", the user inputs a backward signal from the Roman alphabet input section 1 as shown in the 16th row (A) column. . Input the backward signal to the Roman character input section 1 as shown from the 16th line to the 22nd line to the position where the character "H" was input by mistake, and input the Roman character string "SHiZENG" as shown in the 22nd row (d) column. The input Roman character string is stored in the storage unit 2. Next, as shown in lines 23 to 28, enter the Roman character string "ENGOTO" in sequence, and enter the Roman character string "SHiZENGENGOTO", which indicates the Japanese pronunciation "Shizengengoto", in the 28th row (E) column. As shown in FIG. 1, the input Roman character string storage unit receives the conversion signal, and as shown in the 29th row (c) column, the conversion signal is input to the control input unit 3 to obtain the desired kana string ``Shizengengoto''. As mentioned above, conventional Romaji input devices are as shown in Table 1.
As shown in the 8th row (a) column of , if the input Roman character string is inputted incorrectly, the desired character string cannot be obtained, and in order to obtain the desired kana string from the incorrectly converted Roman character string, , after deleting the input Roman character string using the back key as shown in the conventional example, you must either re-enter the correct Roman character string or edit the Roman character conversion result, which makes it difficult to operate when an incorrect input is made. It had the problem of falling. Purpose of the Invention The present invention solves the above-mentioned conventional problems.
When a Roman character string that cannot be interpreted as a Japanese reading is entered, the input is immediately interrupted and processing is performed to deal with the incorrect input, thereby reducing operability even if an incorrect input is made during Roman character input. The purpose of the present invention is to provide a Roman character input device capable of inputting Roman characters. Structure of the Invention The present invention includes an input unit for sequentially inputting Japanese pronunciations using Roman characters, an input Roman character storage unit for sequentially accumulating and storing the Roman characters input from the input unit, and a temporary storage unit for storing the number of characters of the input Roman character string. Search for a Roman character string that can be interpreted as Japanese pronunciation from the beginning of the Roman character string stored in the input Roman character number temporary storage unit and the input Roman character string storage storage unit, and interpret the number of characters in the Roman character string. an interpreted Roman character number temporary storage unit that temporarily stores the interpreted Roman character number outputted from the Roman character search unit; and an input Roman character number temporarily stored in the input Roman character number temporary storage unit. A configuration comprising: a determination interrupt processing unit that reads the number of interpreted Roman characters temporarily stored in the temporary storage unit for the number of interpreted Roman characters, and causes an interrupt when the difference between the input number of Roman characters and the number of interpreted Roman characters is greater than or equal to a predetermined number. As a result, if there is an error in the input Roman characters, the user is immediately notified of the error in the input Roman characters, and a process is performed to correct the errors in the input Roman characters, improving operability when inputting incorrect Roman characters. It is something that can be improved.

【table】

[Table] Table 2 shows the operation of each part when inputting the Japanese pronunciation "Shizengengoto" into the Roman alphabet input device of this embodiment. Column (Ka) indicates the line number, and column (K) indicates Input section 6
The column (h) shows the input to the control input section 13, and the column (k) shows the input to the input Roman character string storage section 7.
Column (C) indicates the number of input Roman characters temporarily stored in the input Roman character number temporary storage section 8, and column (S) indicates the input Roman character string stored in the temporary storage section 10 for the number of interpreted Roman characters. Indicates the number of interpreted Roman characters that are temporarily stored. Judgment interrupt processing unit 11
shall cause an interrupt when the difference between the number of input Roman characters and the number of interpreted Roman characters is 3 or more. First, the first
Assume that the Roman character string "SHiZEN" is input sequentially from the input unit 6 as shown in the sixth line. Next, from the input part 6, the Roman character string "GE" indicating the kana "ge" is input.
However, as in the conventional example, the letter "H" appears after the letter "G" as shown in the 8th row (K) column.
Suppose that you input the character "E" by mistake, and then input the letter "E" as shown in the ninth row (k) column. When the character "E" is input, the number of interpreted Roman characters is 6, which is the number of characters in the Roman character string "SHiZEN" that can be interpreted as indicating the kana "shizen" as shown in the 9th row (sa) column. Further, the number of input Roman characters is 9 as shown in the 9th row (co) column. In this embodiment, since the judgment interrupt processing unit 11 generates an interrupt when the difference between the number of input Roman characters and the number of interpreted Roman characters is 3 or more, the judgment interrupt processing unit 11 sends an interrupt signal to the input Roman character string editing section 12.
Upon receiving this interrupt signal, the input Roman character string editing section 12 sets the input Roman character string storage section 7 to a state in which input of Roman characters is prohibited, and adds the symbol "?" to the Roman character string currently stored and stored in the input Roman character string storage section 7. do. The display unit 15 outputs and displays the Roman character string stored in the input Roman character string storage unit 7 as shown in (g) of the ninth line. By looking at the symbol "?" output and displayed on the display unit 15, the user knows that there is an error in the input Roman character string. The user inputs a backward signal from the input unit 6 as shown in the 10th row (g) column in order to correct a Roman character input error. The number of input Roman characters accumulated and stored in the input Roman character string storage unit 7 is 8 as shown in the 16th row (co) column, and the number of input Roman character strings is stored in the temporary storage unit 10 for the number of interpreted Roman characters.
Since the difference from the number of interpreted Roman characters 6 temporarily stored in is 2, the determination interrupt processing unit 11 transfers the interrupt release signal. Input Roman character string editing section 12
When receiving the interrupt cancellation signal from the determination interrupt processing section 11, the input Roman character string storage section 7 is placed in a state for accepting Roman character input. The user said the 10th
Following the input of the reverse signal shown in the row (K) column, the reverse signal is input again from the input unit 6 as shown in the 11th row (K) column, and the Roman character string "SHiZENG" is inputted in the 11th row (K).
The input Roman character string is stored in the storage section 7 as shown in the column. Next, input the Roman character string "ENGOTO" sequentially as shown in the 12th to 17th rows of Table 2, and input the Roman character string "SHiZENGENGOTO" as shown in the 17th row (q) column. get to. The user then inputs a conversion signal from the control input section 13 as shown in the 18th row (h) column.
When the conversion signal is input to the control input unit 13, the Roman character conversion unit 14 reads the input Roman character string “SHiZENGENGOTO” stored in the input Roman character string storage unit 7, and converts the input Roman character string “SHiZENGENGOTO” to "Working" is output to the display section 15. As described above, according to this embodiment, the input Roman character number temporary storage section 8 temporarily stores the input Roman character number accumulated and stored in the input Roman character string storage section 7.
At the same time, every time a Roman character is input to the input unit 6, a continuous Roman character string that can be interpreted as a Japanese reading is searched from the beginning of the Roman character string stored in the input Roman character string storage unit 7. A Roman character string search unit 9 that outputs the number of characters as the number of interpreted Roman characters, and an interpretation Roman character number temporary storage unit 10 that temporarily stores the number of interpreted Roman characters are provided. By providing a judgment interrupt processing unit 11 that sends an interrupt signal when the difference between the number of interpreted Roman characters temporarily stored in the interpretation Roman character number temporary storage unit 10 becomes 3 or more, the interpretation cannot be interpreted as a Roman character indicating Japanese pronunciation. If three or more characters are input continuously, the difference between the number of input Roman characters and the number of interpreted Roman characters becomes three or more, and the determination interrupt processing section 11 sends an interrupt signal to cause the input Roman character string editing section 12 to perform interrupt processing. , it is possible to prevent the input of a Roman character string following an incorrect Roman character input, and it is possible to improve the operability of Roman character input. In this embodiment, when the input Roman character string editing section 12 receives an interrupt signal, it puts the input Roman character string storage section 7 into the input inhibited state and adds the symbol "?" to the end of the input Roman character string. The column editing unit 12 may be a buzzer sound output unit that generates a buzzer sound to notify the user of incorrect input. Effects of the Invention The Roman character input device of the present invention includes an input section, an input Roman character string storage section, an input Roman character number temporary storage section,
By providing a Roman character search unit, a temporary storage unit for the number of interpreted Roman characters, and a judgment interrupt processing unit, input is immediately interrupted when a Roman character string that cannot be interpreted as a Roman character indicating Japanese pronunciation is input, and processing is performed to deal with incorrect input. This makes it possible to input Roman characters without compromising operability even if an incorrect input is made while inputting Roman characters, which is highly effective.
