Abstract

PURPOSE:To enable spelling retrieval or synonym retrieval to be efficiently performed even during a printing operation, by a method wherein when a retrieval mode is set during the printing operation, a key for retrieval is determined, one of the results of retrieval is decided, and printing is performed while correcting a character string previously printed. CONSTITUTION:When a list mode is started by pressing a specified key after printing 'ab', a printing position pointer 210 is moved leftward from the position at which a carriage has been located, character codes stored in a buffer 21 are checked, and character strings already inputted are displayed on an LCD 3. Editing is performed by using the LCD 3, and when the stem of a word to be retrieved is determined, word retrieval is started. When a return key is pressed after designating 'ab', words beginning with 'ab' are retrieved from a dictionary stored in an ROM 5, and are sequentially displayed on the LCD 3. The character code pointed by the pointer 210 is compared with the code in a character string just determined, from left to right, and when the two codes compared are the same, the carriage is simply fed by one character position. When the two codes compared are different, a correcting. action is performed, and a decided character string stored in a retrieval buffer 40 is printed.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic typewriter that can perform spelling searches and related word searches during printing operations.

[Prior Art] Conventionally, when creating a text, a character string was displayed on an LCD, and the text was checked for spelling, searched for synonyms, edited and corrected on the LCD, and then printed. Also, there was a system that allowed you to check the spelling while printing, but it was not very easy to operate, and you could not make effective use of the string once printed, and you would have to re-enter the same string for a search. It was bad.

[Problems to be Solved by the Invention] In the above-mentioned conventional technology, for example, when entering the spell search mode after printing ab, inputting ab again and entering the LC
The operability was very poor, such as displaying it on D and then searching. The present invention solves these problems,
To provide an electronic print writer capable of efficiently performing a spell search and a synonym search even during printing operation.

[Means for Solving the Problems] The present invention provides means for instructing to enter a word dictionary search mode, and a character string input from an input device when the search mode is started according to the instruction from the instructing means. a search buffer for storing as a key for searching the dictionary in correspondence with editing work performed on a display device;
means for selecting one of the candidate character strings searched based on the key and storing the character string; and means for printing the finally determined character string from the print position at the time the search mode is entered. It is characterized by being configured.

[Function] In the present invention, when the search mode is entered during the printing operation, the search key is determined using previously printed characters, and one of the search results is finally determined. To print a character string while erasing previously printed character strings as necessary.

[Embodiment] FIG. 1 is a block diagram schematically showing an embodiment of an electronic typewriter of the present invention. Here, a character string is input from the keyboard 2, and the character string is input to a buffer (not shown) in the RAM 6, and is also displayed on the LCDa.

Further, when the editing work or the like is completed using the LCD 3, the character string is printed by the printer 4.

In addition, a control program is stored in the ROM-5, and the CP
The UI executes the control program and performs overall control. Further, 7 is an auxiliary storage device, for example, an IC card, in which test programs and the like are stored.

FIG. 2 shows the configuration of a buffer 21 that stores character strings input from the keyboard 2 on RAMe, and an attribute buffer 20 that shows the attributes of each character (bold character, underline, etc.) of the buffer. It shows.

Further, 210 is a print position pointer, which corresponds to the position of the printer carriage.

Now, as shown in Figure 3(b), after printing ab, press a specific key to enter the word spelling display mode (hereinafter referred to as
Set to list mode. ). An arrow 310 indicates the position of the printam carriage at this time. At this time, the contents of the buffer 21 are as shown in FIG.

When the list mode is entered, the print position pointer 210 is moved to the left in FIG. , the character codes stored in the buffer 21 are examined. Then, move the delimiter such as a space until it is found immediately to the left. At this time, the carriage is also moved to the first letter of the word that you are about to type.

By moving this print position pointer to the left, it is recognized what character code has been input before, so based on the code, the character code is displayed on the LCDa as shown in Figure 3 (a). The input string (the string of characters from where the carriage was before entering list mode, moving leftward until the delimiter is immediately next to it) is displayed.

In FIG. 3(a), the cursor 320 indicates the next input position, but you may input more characters after this, or you can backspace and erase the displayed a and b. You may enter a completely different string. The input character string at this time is stored in a search buffer 40 (FIG. 4), which is different from the buffer 21, in a one-to-one correspondence with the character string displayed on the LCD 3. Here, the search buffer 40 also exists in the RAM 6.

Once the stem of the word to be searched for has been determined by editing using the LCD 3, the user presses the return key, for example, to start searching for the word.

In this case, if you press the return key with "ab", the ROM
Search the dictionary stored in 5 and find the word r starting with "ab"
LC "abandon", "rabnormal" etc.
It will be displayed on the DB. In this case, for example, if the LCD 3 is relatively small, it may be possible to display -words one by one and press a specific key to select the next candidate.If the LCD 3 is relatively large, multiple candidate words may be displayed. may be displayed at once, and a number may be designated and selected from among them.

The candidate words to be displayed are confirmed by, for example, pressing the return key. The determined character string is then stored in the search buffer 40, for example.

Once the spelling of the word is determined in this way, the next step is printing, at which time the print position pointer 210 and the carriage described above are at the first character of the word. When printing, the character code indicated by the print position pointer 210 and the code of the character string just determined are compared from the left side (that is, from the beginning of the word), and if the codes are the same,
A single digit carriage is simply sent, and if the code is different, an erasing operation is performed first, and then the determined character string stored in the search buffer 40 is printed. Then, while moving the carriage rightward one digit at a time, this operation is repeated one after another, and all the character strings stored in the search buffer 40 are printed. At this time, the attributes of the previously input character string are recognized by referring to the attribute buffer 20, and the new character string is printed with the same attributes as the previous one. However, as shown in FIG. 5(a), at first, abnor
If mal is printed, the carriage is returned to point b, the list mode is entered, and "abandon" is selected, even if the character n is printed, the previous 1 still remains.

In such a case, for example, first, the printing position pointer 210 is checked to the left on the buffer 21 to determine the initial display character string on the LCD 3, and then the delimiter is found further to the right. Print position pointer 210
, find out how many characters the input string consists of, and memorize that value. Thereafter, the print position pointer 210 is returned to the beginning of the input character string.

If you memorize in advance how many characters were entered before entering list mode as described above, even if you print anew "abandon" as shown in Figure 5, unnecessary characters will still remain. is recognized, and the erase operation is performed while moving the carriage to the right by the number of characters.

Further, in the above explanation, the word stem was taken as an example, but the same can be applied to, for example, the ending of a word or a character string in the middle of a certain word.

If it is at the end of a word, cut out the character string where the next delimiter is located when looking to the right from the carriage position before entering Squirrel] mode, or if it is in the middle, cut out the character string where the next delimiter is located. - After entering the mode, it is possible to specify the target character string area by moving the carriage, etc.

In addition to spell checking, you can also search for synonyms. In the case of a synonym search, the key is not a character string but a word, so words are always initially displayed on the LCD 3 as shown in FIG.

When the synonym search mode is entered by pressing a specific key, etc., delimiters are searched on the buffer 21 in both the left and right directions from the position of the pointer 210 before entering the mode, and the word to be the key is determined. In other words, the word Bo is used regardless of whether the carriage is at B, 0, or a immediately before the mode.
at is extracted and one word is initially displayed on the LCDa.

The subsequent operations are similar to the spell search described above.

Further, here, the explanation has been given using an example of searching for synonyms, but the same applies to related words such as antonyms.

Furthermore, as shown in FIG. 7, the paper can be fed in the opposite direction and the spelling search and related word search described above can be performed on the previously printed characters. However, in this case, due to the capacity of the buffer 21, it is not possible to store all previously input character strings. Therefore, in such cases, it is not possible to decide which part of the previously printed character string to use for spelling search, or which word to search for related words, when entering each mode. , I have no idea. Therefore, nothing is initially displayed on the LCD 3 when each mode is entered, and the character string input thereafter becomes the key in each mode.

The subsequent operation is the same as described above, but when printing, it starts from the position where the carriage was before entering the mode, without comparing the character code with the previous input character string (memorized). I don't have one so I can't compare.

), erasing, and printing are sequentially moved to the right one digit at a time, and printing continues until all the final character strings are completed. Further, this operation of reversing the paper feed is performed, for example, by pressing a specific key, but by pressing the key, a flag is set and a mode is entered in which the contents of the buffer 21 are not referenced.

[Effects of the Invention] As described above in detail, according to the present invention, spelling searches and related word searches can be performed during printing operations by searching for delimiters on the buffer and inputting new character strings. This makes writing the text much easier.

Furthermore, in a spell search, the already input character string is used as is and initially displayed on the LCD, and when printing, the same characters as before are used, so the efficiency of the correction operation is improved. In addition, when searching for related words, before entering the mode, a key for one word is automatically cut out no matter where the carriage is in the word, and when it comes to printing, the previously printed character string is Efficiency can be greatly improved by making full use of it.

Furthermore, since a flag indicating that the paper has been reversely fed is used, by determining this flag, it is possible to perform a spelling search and a related word search for previously printed portions that are not stored in the buffer.
