A search for candidate words is performed (32). Next, it is determined whether a candidate word for the valid character string "Wiggle-wiggle" is registered (33), and YE
If S, execute candidate word selection processing routine (34).
, the word "wiggle-waggle" indicated by the cursor K of the collection buffer 6d shown in FIG. 3(f).
After redisplaying the line display containing (35), step (
Return to 1).

On the other hand, in the candidate word selection processing routine in steps (30) and (34) above, first, the process shown in FIG.
As shown in d), candidate words are displayed (36), and then the key scan data is read from the key scan buffer 6a in which the key scan data input from the keyboard 2 is stored. The data is input to the data 6b (37). Next, it waits for a key input (38), and stores the key in the key scan buffer 6a.
If the scan data 6b is stored, it is determined whether the key input is a key that prompts selection of a candidate word (39).
, if YES, the next candidate word is selected (40), and the process returns to step (36); if NO, it is determined whether the key prompts the selection of the currently displayed candidate word (41);
If NO, the process returns to step (37) after sounding an error buzzer (42).

On the other hand, if YES in step (41), the currently selected and displayed candidate word "wig"

By replacing the word "weggle" indicated by , the word is automatically corrected (43) and the process returns to the main routine.

[0030] In the above embodiment, especially the typing mode
The process shown here shows the processing procedure in C/C mode, L/L mode, but it is also possible to determine the misspelling of the word indicated by the cursor K in the registered document that has already been registered, and also to use the spell corrector. By selecting candidate words using the dictionary,
It is also possible to automatically correct misspelled words.

[0031]

As explained above, the present invention provides an effective character string that automatically detects a valid character string for an input word based on the detection result of correct spelling word candidates for the input word by the candidate search means and displays it on the display means. Since the detection means and the restart means automatically restart the correct spelling word candidate search process by the candidate search means based on the selection instruction for the valid character string detected by the valid character string detection means are provided, it is impossible to search for candidates in the past. To effectively and reliably perform correct spelling character search processing and correction processing for a word consisting of a character string including a symbol such as , with a small number of key operations.

[0032] Furthermore, since the valid character string detection means is configured to detect valid character strings based on symbols or specific codes in the input word, it is possible to detect valid character strings based on symbols or specific codes in the input word. Even if there are characters, it is possible to reliably detect character strings that are effective for candidate search.

[0033] Therefore, the correct spelling word candidate selection process is effective even for words consisting of character strings that include symbols that make it impossible to search for candidates, and effects such as the ability to significantly improve the correct spelling word candidate processing efficiency are achieved. .
