CONSTITUTION:An instruction means is provided to instruct the actuation of a candidate word display means in order to cope with the spelling mistakes detected by a spelling check means. A wrong word erasing means works by an instruction of the instruction means and erases the wrong words printed by a print means. Then a selection means can select the desired one of those candidate words displayed by the candidate word display means after the actuation of the wrong word erasing means. When a misspelling is detected, the print of the wrong word is automatically erased. Then an operator operates the selection means to select the desired one out of plural candidate words displayed by the candidate word display means.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a typewriter having a spell check function, and more particularly to means for dealing with misspellings when they are discovered.

BACKGROUND OF THE INVENTION Typewriters are already known that have the ability to detect misspellings in printed words based on keystrokes and suggest candidate words to replace the misspelled words. This type of typewriter has a printing means for printing character data input from an al keyboard, and a (
b) storage means for storing the character data; and (c
) Spell check means for checking whether or not there is a s(lumis) in the word stored in the storage means in response to input of delimiter data such as a space or a period for delimiting character data of one word from other words; (d) Candidate word presenting means for presenting a candidate word to be printed in place of the erroneous word including the misspelled word when a spelling error is discovered by the spell checking means.

When one word is selected from among the plural words presented by the candidate word presentation means, the incorrect word printed in accordance with the selection operation is erased, and the selected candidate word is corrected. Since the words are printed as words, the operator has the advantage of requiring only a few operations to correct misspelled words.

Problems to be Solved by the Invention However, in this typewriter, a correct word to be replaced with the incorrect word must be selected before erasing the incorrect word, which results in a reduction in work efficiency. Ta. In other words, since it takes a certain amount of time to erase an incorrect word, when an incorrect word is found, it is first erased, and during the erasure, the operator thinks about what word to print in place of the incorrect word. Although this method is more efficient, it was previously inefficient because the correct word had to be determined before starting to erase incorrect words.

Additionally, with conventional typewriters, once erasing has started, the incorrect word is completely erased, and the operator cannot intervene in the operation of the typewriter until the correct word has been printed. . Since it takes a certain amount of time to erase the incorrect word and print the correct word, the operator often changes his mind during that time and wants to print a different word from the one he has already selected. In such a case, in conventional typewriters, once a word has been selected, it is always printed, which causes the inconvenience of having to erase the word again and print another word.

Means for Solving the Problems The present invention aims to solve the above problems by providing the keyboard, storage means, and printing means, as shown in FIG.

In a typewriter equipped with a spell check means and a candidate word presentation means, (a) an instruction means for instructing the operation of the candidate word presentation means in order to deal with the spelling error when a spelling error is discovered by the spell check means;
(b) Erroneous word erasing means that operates in response to an instruction from the instruction means and erases the incorrect word printed by the printing means; The gist of the present invention is to provide a selection operation means that allows a user to select a desired word from among candidate words.

Function: In the typewriter configured as described above, when a misspelling is detected by the spell check means, the misword erasing means automatically erases the misprinted word in response to an instruction from the instruction means to operate the candidate word presentation means. However,
After the deletion, the operator operates the selection operation means to select a desired word from the plurality of candidate words presented by the candidate word presentation means.

Effect In this way, since it is possible to select a desired word from a plurality of words presented by the candidate word presentation means after erasing an erroneous word, the operator can select the desired word while erasing an erroneous word. You can think of correct words to print in place of incorrect words.

Therefore, the time during which incorrect words are deleted can be used more effectively than in the conventional method, resulting in the effect of improving work efficiency.

In addition, the operator's thinking has changed since the candidate word presentation means is selected once, and after the incorrect words are erased according to the selection, the desired word is selected from among the candidate words by operating the selection operation means. In this case, it is possible to eliminate the inconvenience of having to erase the selected candidate word again and reprint other words after the printing of the selected candidate word is completed as in the conventional method.

Figure spell check control program and dictionary memory 1
Based on the data of 02, spell check calculation processing is performed on the input word.

Further, the CPU 46 sequentially stores the printed code data in correspondence with the printing position in the print data memory 112 of the RAM 54, and also stores data on the current position that changes each time the carriage drive motor 31 or the type wheel drive motor 34 is driven. It is stored in the current position memory 114 and the type position memory 116 of the RAM 54.

Then, the CPU 46 processes the code data input from the various function keys of the keyboard 3 using the control program read from the program memory 100 of the ROM 53, thereby transmitting control signals corresponding to the input code data to each of the drivers 39, 47 to 51. and output to the display controller 52.

Furthermore, the CPU 46 selects the character key 4 of the keyboard 3.
. Thereby, a control signal corresponding to the code data is outputted to each of the drivers 39, 47 to 51 of the printing mechanism driving means PM and the display controller 52, thereby controlling the printing mechanism and the display device.

That is, the printing mechanism driving means P based on the code data
When controlling M, a control signal is output from the CPU 46 to the type wheel drive motor driver 51, and the type wheel drive motor driver 51 outputs a control signal to the type wheel drive motor 3.
A drive current is output to 4. Then, the type wheel drive motor 34 rotates by a predetermined angle, and the type 36 of the type wheel 33 corresponding to the code data is placed in the printing position in front of the printing hammer 37, and at the same time, the CPU 46
A control signal is output from the ribbon lift motor driver 50 to the ribbon lift motor driver 50, a drive current is output from the ribbon lift motor driver 50 to the ribbon lift motor 45, and the rotation of the ribbon lift motor 45 causes the holder 4 to be moved through the drive shaft and cam mechanism.
2 and printing ribbon 40 are swung to the printing position shown in FIG.

Next, the CPU 46 sends the print hammer solenoid driver 3
When a control signal is output to the print hammer solenoid driver 39 , a drive current is output from the print hammer solenoid driver 39 to the print hammer solenoid 38 , and the print hammer 37 drives the print wheel 33 .
The printed characters 36 are struck, and the characters are printed on the printing paper P.

Then, if there is no next key input within a predetermined time, C
A control signal is output from the PU 46 to the ribbon lift motor driver 50, the ribbon lift motor 45 rotates, and the holder 42 and print ribbon 40 are returned to the rest position.

Furthermore, control signals are output from the CPU 46 to the carriage drive motor driver 48 and the ribbon feed motor driver 49, respectively. In response, a drive current is output from the carriage drive motor driver 48 to the carriage drive motor 31, the carriage drive motor 31 rotates by a predetermined amount, and the carriage 27 is moved in the single character printing direction via the wire 32. Ribbon feed motor driver 49
A drive current is output from the ribbon feed motor 43 to the ribbon feed motor 43, which rotates by a predetermined amount to feed the printing ribbon 40.

Further, when the return key 9 is operated, the CPU 46 processes the code data from the keyboard 3 with the control program read from the program memory 100 of the ROM 53 to send control signals to the carriage drive motor driver 48 and the platen drive motor driver 47. Output. Then, a drive current is output from the carriage drive motor driver 48 to the carriage drive motor 31, and the carriage drive motor 31 rotates in the reverse direction to return the carriage 27 to the print starting position. At the same time, a drive current is output from the platen drive motor driver 47 to the platen drive motor 25, the platen drive motor 25 rotates by a predetermined amount, and the printing paper P is fed by one line.

Further, when operating the erase key 23 to erase characters on the printing paper, the CPU 46 reads a character erase control program from the program memory 100 of the ROM 53 and outputs a control signal to the ribbon lift motor driver 50. As a result, the ribbon lift motor 45 is rotated and the holder 42 is swung to the correction position shown in FIG. The CPU 46 then stores the current position memory 1 in the RAM 54.
14, data in the print data memory 112 corresponding to the print position of the print head is read out, and a control signal is output to the type wheel drive motor driver 51.
The type wheel 33 is rotated by the type wheel drive motor 34, and the type 36 which is the same as the character to be erased is
is positioned at the printing position, the printing hammer solenoid 38 is driven by the drive current from the printing hammer solenoid driver 39, and the printing hammer 37 hits the printed characters 36, thereby erasing the printed characters on the printing paper P.

In the above case, when erasing the print of a series of characters currently being input, the code data corresponding to the erased print character is erased from the buffer memory 106.

In this typewriter 1, an incorrect word including a misspelling is detected in the spell check mode, and after the operator is informed of this fact, the operator
By selecting a desired menu from four menus: retype, amend, and correct, it is possible to choose how to deal with the incorrect word. Evennois is a menu that is selected when continuing the work without making corrections when the word that was determined to be an erroneous word is a proper noun or the like and is not actually an erroneous word.

Retype is a menu that is selected when the operator wants to print another word by inputting the keys after erasing the misprinted word. Amend corrects some characters of the misword. This is selected when a wrong word can be corrected to a correct word by doing so. Further, the SADGE SOTION is a menu selected when the operator requests the typewriter to present candidate words to replace the incorrect word, and selects and prints a desired word from among the presented candidate words.

These points will be explained in detail below, but first, detection of incorrect words will be explained based on the flowchart of FIG.

When the spell check key 17 is operated, the spell check mode is set in Sl, and SP is displayed on the display 21 in S2. Subsequently, after the buffer memory 106 is cleared in S3, S4 is repeatedly executed to enter a state of waiting for a key input.

If any key on the keyboard 3 is operated, S5
It is determined whether the operated key is a delimiter key such as space, line feed, comma, period, etc., and if it is a delimiter key, S6 is executed, but if not, the cancel key 20 is executed in S7. It is determined whether or not. If the cancel key is pressed, the spell check mode is canceled in S8, and the execution of this control program ends. That is, the spell check mode is set by operating the spell check key 17, and the spell check mode is canceled by operating the cancel key 20.

If the determination result in S7 is No, it is determined in S9 whether or not the operated character key is character key 4, 5. The code data of the character is stored in the buffer memory 106, and the
At 1, printing is performed on the printing paper P, and S4 is repeated to return to the state of waiting for key input. Also, the determination result in S9 is N.

If so, the process returns to S4 after other keys are processed in S12.

After a certain amount of character data is stored in the buffer memory 106 as described above, if the separator key is operated, the determination result in S5 becomes YES, and in S6 it is determined whether or not there is data in the buffer memory 106. will be held. If the result of this determination is NO, 313~
The operation corresponding to the delimiter key is performed in S20, bypassing S19, but since the data is stored in the buffer memory 106, S6
The determination result is YES, and in step 313 it is determined whether or not the first character of the character string stored in the buffer memory 106 is an alpha bent. If it is not an alpha vent, the data of the symbol preceding the alpha vent is stored in the previous symbol memory 10 in S14.
7 He is stored. If there are multiple symbols preceding the alphabet, all of those multiple symbols are stored in the previous symbol memory 10.
7 He will be saved. Next, in S15, it is determined whether or not the last character in the buffer memory 106 is an alpha vent, and if it is an alpha vent, S
17 is executed, but if it is not an alphabet, all data of the last symbol is stored in the post symbol memory 108 in S16. Then, in S17, only the alphabetic character string in the buffer memory 106 is transferred to the word memory 110, and in 318 it is determined whether or not there is data in the word memory 110.

If there is data, it is determined in S19 whether the spelling of the character string in the word memory 110 is correct. A check is made to see if a character string equal to the character string in the word memory 110 exists in the dictionary memory 102, and if so, it is assumed that the spelling is correct and the process proceeds to step S2.
At 0, the operation corresponding to the delimiter key is performed.

For example, when the delimiter key is the space key 7, the carriage is moved to one character distribution without printing, and when the delimiter key is the return key 9, a new line action is performed.

At the time of determination in S18, if there is no data in the word memory 110, or even if there is data, in S19, if there is no character string corresponding to the character string in the dictionary memory 102, the character string stored in the word memory 110 is is determined to be an incorrect word, and the operator is notified of this fact by an alarm buzzer in step 321.

Subsequently, the erase flag 120 is cleared in S22, and the buffer memory 1 is displayed on the display 21 in S23.
06 character string (a character string that includes not only alphabets but also symbols and numbers is displayed)
(This point will be explained in detail later) is displayed as an incorrect word, and a menu is also displayed for allowing the operator to select a method to deal with the incorrect word. Ignore, retype.

The Amend and Sajiesojeon menus are displayed.

If the operator operates the cursor movement key 22 according to the display, the determination results of 823' and S24 will be YES.
Then, in S25, the cursor is moved to Ignore, Retype, and Amend.

One of the sajie sojon is selected. After that selection,
If the operator operates the return key 9, the determination result in S26 becomes YES, the selected menu is determined in S27, and the selected menu is thereafter executed. Note that if it is the cancel key 20 that is operated after the incorrect word is displayed, the determination result at 328 is YES and the spell check mode at 38 is canceled, but the cursor movement key 22. Return key9. If a key other than the cancel key 2o is operated, an alarm buzzer sounds in S29 to notify the operator that the process corresponding to that key is impossible.

The operation of each menu will be explained below.

First, if ``Evennoa'' is selected, the operator wishes to continue the work without erasing the word that was identified as an incorrect word, so after the display of the incorrect word is erased in S30, In S20, the operation corresponding to the delimiter key is performed as usual.

On the other hand, if retype is selected, the process shown in the flowchart of FIG. 7 is performed.

First, in S31, it is determined whether or not the erasure flag 120 is set, but since it is normally not set, each character of the incorrect word printed on the printing paper P is erased in S32. . At the same time as this erasure, the data in the buffer memory 106 is also cleared,
If the incorrect word is accompanied by a symbol, the symbol is also deleted. Thereafter, the erase flag 120 is set in 333, and S34 is repeatedly executed to wait for a key input. If the operator operates the cursor movement key 22 in this state, the determination result of 335 becomes YES,
The cursor is moved in S36. If the operator operates the character key after moving the cursor to the desired position, the determination result in S34 will be YES, but 3
35. The determination results in S37 and S38 are NO, and the program execution moves to 85 in FIG. 6, where printing is performed in accordance with the operator's key input.

However, once the beam type has been selected, if the operator changes his or her mind and wishes to select another menu, the cursor is moved to a position corresponding to the desired menu by operating the cursor movement key 22. After that, just operate the return key 9. As a result, the determination result in S37 becomes YES, and in 339 it is determined whether the cursor is located at a position corresponding to any menu. If the result of this determination is No, the program execution returns to S34, but if it is YES, step 32 in FIG.
7, the menu can be reselected.

Furthermore, even after the type is selected, if the cancel key 20 is operated, the program will not be executed at 8 in FIG.
8 and the spell check mode is canceled. Furthermore, after selecting the retype menu, another menu may be selected, but retype may be selected again. In this case, the deletion flag is set to 1 in S33.
Since 20 is set, the judgment result of S31 is YE.
Since S32 and S33 are bypassed,
Erroneous words will not be erased again.

If the operator determines that the incorrect word displayed on the display 21 will become a correct word if part of it is corrected and selects "Amend", processing based on the flowchart of FIG. 8 is performed.

First, in 340, it is determined whether or not the erasure flag 120 is set, but the result of this determination is usually No, the printing of the incorrect word is erased in S41, and the erasure flag 120 is set in S42. Ru. Subsequently, in S43, the cursor is moved to the first character of the incorrect word displayed on the display 21, and then S44 is repeatedly executed to wait for a key input. In this state, the operator presses the cursor movement key 22.
If you operate , the judgment results of S44 and S45 will be YES.
Then, the cursor is moved in S46. That is,
At the same time as amend is selected, the cursor is automatically moved to the position of the first character of the incorrect word, and the operator can move the cursor from that position to the position of the desired character by operating the cursor movement key 22. be.

Next, if the operator operates the character key, S4
5. S47. The determination results in S48 and S49 are No, the determination result in S50 is YES, the character at the cursor position on the display 21 is replaced with the character corresponding to the operated character key, and the cursor is moved one character to the right. After being moved to , program execution returns to S44.

After the incorrect word is corrected by repeating the above operations, when the operator operates the return key 9, the determination result at 348 becomes YES, and S52 is executed. cursor is 1
It is determined whether the cursor is pointing to a single word, that is, whether the cursor is located at a position corresponding to any of the characters that make up one word, and the result of the determination is If YES, the word indicated by the cursor is printed in S53, and then the program execution moves to 320 in FIG.

However, if the cursor does not point to a word, the program execution returns directly to S44.

Furthermore, if the operator wishes to delete one character in an erroneous word, he may operate the delete key 18. If the delete key 18 is operated, S45,3
The determination results of S47 and S48 are NO, the determination result of S49 is YES, and S54 is executed, the l character specified by the cursor on the display 21 is deleted, and the character to the right of it is moved one pitch to the left. It can be slid. Thereafter, the program execution returns to S44.

Furthermore, if the operator changes his mind after once selecting Amend, he may operate the cursor movement key 22 to move the cursor onto the menu, and then operate the return key 9. In this case, the determination results in S47 and S46 become Y'ES, and the program execution proceeds to S27, allowing the menu to be selected again.

Note that if the cancel key 20 is operated while the cursor is on the menu, the determination result in S47 is YES, and S4
The determination result of 6 is No, the determination result of 355 is YES, and 88 in FIG. 6 is executed, and the spell check mode is canceled. This spell check mode can be canceled by operating the cancel key 20 even when the cursor is on any character of an incorrect word. In this case, the determination result in 344 is YES, and S45. S47. S48. After the determination results in S49 and S50 are NO, the determination result in S55 is YES, so S8 is executed and the spell check mode is canceled.

When the operator selects the suggestion menu to ask the typewriter to suggest a correct word to replace an incorrect word, processing based on the flowchart of FIG. 9 is performed.

First, like when any other menu is selected, 356
~358 is executed and the printing of the incorrect word is erased, then S
At 60, it is determined whether there are any candidate words. That is, words with spellings similar to incorrect words are stored in the dictionary memory 102.
A determination is made as to whether or not it is within the range, and if so, S6
After all candidate words are displayed on the display 21 in step 1, S62 is repeatedly executed to wait for key input. The candidate words are displayed together with symbols as shown in FIG. The symbols stored in the leading symbol memory 107 and the trailing symbol memory 108 are stored in the dictionary memory 10.
It is displayed together with the candidate words discovered in step 2. As explained earlier, if an incorrect word is accompanied by a symbol, that symbol is also deleted when the incorrect word is deleted, but candidate words to replace the incorrect word are also displayed along with the symbol. It is. In addition, the display 21
A menu is also displayed at the top along with the incorrect word.

If the operator operates the cursor movement key 22 in this state, the determination result at 363 becomes YES and 364
is executed and the cursor is moved. If the operator operates the return key 9 after moving the cursor to any position of the candidate words presented, the determination result of 365 becomes YES, and in S66 it is determined whether the cursor is on the candidate word or not. Here, the result of the determination is YES, and in 367, the candidate word is printed. At this time, if the candidate word displayed on the display 21 is accompanied by a symbol, the symbol is also printed.

On the other hand, if the return key 65 is operated after moving the cursor onto a menu because the desired word is not found among the candidate words presented or the user wants to change to a menu other than suggestion. In this case, the determination result at S66 is NO, the determination result at 568 is YES, and the program execution moves to 327 in FIG. 6, where the menu selection is performed again. Note that even if this menu selection is made again, the display on the display 21 in FIG. 10 remains unchanged.

Further, if the determination result of 360 is NO1, that is, there is no word with a spelling similar to the incorrect word in the dictionary memory 102, S69 is executed, and the display 21 displays that there is no candidate word, as shown in FIG. Not for
und is displayed, and the state waits for a key input in S70. If any key is operated in this state, the execution of the program shifts to 324 in FIG. 6, and another menu can be selected. If the desired word is not found among the suggested words, select the retype menu and type in the desired word, or select the amend menu to correct some of the incorrect words. It is possible. Even after reselecting this menu,
The display in FIG. 11 remains unchanged.

Furthermore, even after the Sajie '7 section menu is selected, if the cancel key 20 is operated, S63.
S65. After the determination results in S66 and S68 are NO, the determination result in S71 is YES, and 88 in FIG. 6 is executed to cancel the spell check mode.

In this way, this typewriter has the feature that the operator can select various menus after a missword is discovered as a result of the spell check, but in addition, when displaying a missword, the missword is accompanied by a symbol. This feature has the feature that if a missword is found as a result of spell checking, the symbol is also displayed, and the execution of the action corresponding to the delimiter key is stopped if a missword is found as a result of spell checking. These features will be explained in detail below.

First, we will explain how incorrect words are displayed together with symbols.

As mentioned above, when performing a spell check on a series of character data stored in the buffer memory 106, if the character data includes symbol data, the spell check is performed on a character string consisting only of alpha vents, excluding symbol data. However, when the discovered incorrect word is displayed on the display 21, it is better to display it together with a symbol. As in the past, when only the incorrect word excluding the symbol is displayed, whether or not the symbol is also printed when the correct word to replace the incorrect word is selected and printed on the printing paper. This is because the operator is uncertain and the operator feels uneasy.

On the other hand, in this embodiment, the display of incorrect words performed in step 323 of the flowchart of FIG. 6 is performed together with symbols. Although misspellings are checked based on the data in the word memory 110, when the data is displayed on the display 21, the previous symbol memory 107. The data in the word memory 110 and the post-symbol memory 108 are displayed together. At 367 in FIG. 9, not only the candidate word but also the symbols stored in the leading symbol memory 107 and the trailing symbol memory 108 are printed, and there may be a discrepancy between the display on the display 21 and the printed one. Since there are no errors, the operator can perform input operations with peace of mind.

Next, a description will be given of how to stop the operation corresponding to the delimiter key when a wrong word is found.

As mentioned above, in this typewriter, spell checking is performed according to the operation of the separator keys.
If the operation corresponding to the separator key is performed at the same time as the spell check is performed, this operation is often wasted. For example, if a misspelling due to an omission of a character or the addition of an unnecessary character is discovered in response to the operation of a comma or period separator key, the length of the incorrect word containing the misspelled word and the correct word are different. The positions of commas and periods also change, and these must also be deleted. In addition, if the separator key is the space key or return key, the carriage must be returned to the position of the incorrect word in order to erase the incorrect word, so the return operation or space feed is wasted. It will become.

However, in this typewriter, as is clear from the above description, misspellings are checked in response to the operation of the separator key, but the operation corresponding to the separator key is canceled. As a result of the spell check, after it is confirmed that there are no spelling errors, or after the incorrect word is erased and the correct word is printed, 320 in Figure 6 is executed, and the operation corresponding to the delimiter key is executed. Therefore, the above-mentioned waste is avoided.

As is clear from the above description, in this embodiment, the puffer memory 106 constitutes the storage means, and the platen 24. Carriage 27. Type wheel 33. Printing hammer 37. The printing ribbon 40 and its driving device constitute a printing means.

Further, the dictionary memory 102 of the control device C and the part that executes 319 in FIG. constitutes the candidate word presentation means.

Furthermore, 3 in FIG. 6 of the keyboard 3 and the control device C
23', 324. S25,326. The part that executes S27 and the like constitutes an instruction means.

Further, S57 in FIG. 9 of the printing means and control device C including a correction ribbon 44 instead of the printing ribbon 40
The part that executes S62. in FIG. S63,3
64. S65. The portion that executes S66 and the like constitutes a selection operation means.

In addition, in this embodiment, when the Evennois menu is selected after an incorrect word is detected, the operation corresponding to the S20 separator key is performed. It is also possible to perform an operation corresponding to the same delimiter key that triggered the operation when the same delimiter key is operated again. For example, if the space key 7 is operated after entering a proper noun, and as a result of the spell check performed according to the operation of the separator key 7, it is determined that the word is an incorrect word, the space key 7 is operated again. By doing so, it is possible to perform a space advance without deleting the proper noun.

Although not illustrated in detail, the present invention can be implemented in various modifications and improvements based on the knowledge of those skilled in the art.
