Abstract

PURPOSE:To simplify an error correcting operation and to improve operability by temporally stopping operation following spelling check processing at the time of detecting a spelling error. CONSTITUTION:When space key operation B is executed after the input operation A of one word in a word mode or a right-justify mode, the spelling check processing C of the word is executed. When the word has an error, the word is stored in an error detecting memory E and printing is canceled by a printing operation canceling means F. When the space key operation B is executed again, the word concerned is unconditionally printed out D by a printing operation cancel releasing means G. Thereby, a typist can simply correct the incorrect word.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an electronic typewriter with a spell check function that performs a spell check process for manually written words, particularly in the [Word] mode and [6]. The present invention relates to an electronic typewriter with a spell check function that improves the operation after spell check is executed in the "Right Justify" mode.

[Prior Art] Generally, an electronic typewriter with a spell check function has a built-in spell check unit that has a dictionary memory that stores the correct spelling of each word for which keystrokes are expected to be required. When a word is entered manually and the space key is subsequently pressed, the spelling of the word entered immediately before that key is checked. When a spelling error is detected, a warning sound such as a buzzer is output. Therefore, when the typist hears the warning sound, he or she first confirms the erroneous character in the printed word by manually pressing the keys, moves the carriage back to the position of the erroneous character, and performs a correction operation on the character.

In addition, some electronic typewriters have a normal [Type] mode that immediately prints characters entered manually using the keys.
For example, it is equipped with a display that can display more than ten characters at the same time.
During the input operation of a word consisting of multiple characters, each character is displayed one after another on the display without performing the printing operation, and when the space key indicating a word separation is pressed, each character of the word is printed together. [Word] mode for printing out, and 1 for storing one line of character data input manually.
Equipped with a line buffer, after manually inputting one line of character data, press the space key or carriage return (OR) key while the key input position indicated by the carriage position is located at the preset right margin (RM) position. When you press the key, the spacing between each word that makes up one line is automatically adjusted so that the right edge of the oldest word on one line automatically matches the margin position. Some printers have a right-justify mode in which words are printed together.

Therefore, typists can use the above spell check function (
mode), [Word] mode, and [Right alignment] mode in combination as appropriate.

[Problems to be Solved by the Invention] However, even in the above-mentioned electronic typewriter with a spell check function, the following problems still exist.

For example, if you manually press a word at 6 o'clock and then press the space key, the spelling process for the word will be executed. Then, the corresponding word is automatically printed. Therefore, if a misspelled word is detected in a manually typed word, a short beep will alert the typist, but by the time the typist hears the beep, the incorrect word will have been printed and the carriage will have no spaces. The action has been executed and the text has been moved to the next word input position.

Therefore, if a spelling error is noticed and the error is to be corrected, it is necessary to move the carriage to the position of the previously input word by operating a key such as the backspace key.

As a result, the error correction operation becomes extremely complicated, and the operability of the electronic typewriter as a whole deteriorates.

- Also, a similar problem occurs in the [right alignment] mode. That is, each word in one line is spell-checked by operating the space key, but each word is not printed at that point. However, if the right end of the last word in a line is located one position to the left of the right margin (RL) position, and the carriage position is located at the right margin position, pressing the space key will check the spelling of the word to the left. At the same time, the above-described cloth layer processing is executed and each word for one line is printed all at once.

Therefore, the word to the left of the light margin (RM) position (
Even if a spelling error occurs in the last word) and the error is confirmed by a buzzer or the like, that word has already been printed.

The character input position indicated by the carriage position has been moved to the right end.

As a result, the task of correcting the corresponding word becomes complicated.

The present invention simplifies the word error correction operation by temporarily stopping the operation following the spell check process when a spelling error is detected by operating the space key in [Word] mode or [Right alignment] mode. It is an object of the present invention to provide an electronic typewriter with a spell check function that can be operated easily and greatly improves operability.

[Means for solving the problem] As shown in FIG.
A spell check that performs a spell check process C for a word in response to a space key operation B executed later, and also performs a printing operation for the corresponding word! In an electronic typewriter with a 1 m function, there is an error detection memory E that stores spelling errors detected in the spell check process C executed by pressing the space key 8, and when a spelling error is stored in this error detection memory E. This apparatus includes a printing operation canceling means F for canceling the printing operation, and a printing operation canceling means G for performing the printing operation in response to the space key operation B performed again after the printing operation is canceled.

In addition, another invention performs a word spell check process C in response to a space key operation B performed after one word input operation A, and performs a word spell check process C in response to a space key operation on a right margin position. In an electronic typewriter with a spell check function that performs a 6-line printing operation H for words in a line, detection is performed in spell check processing C for a word before the light margin position executed by a space key operation B' on the light margin position. There is an error detection memory E that stores spelling errors that have been written, and when a spelling error is stored in this error detection memory E, a 6-line printing operation H is performed.
The apparatus is equipped with a printing operation canceling means F for canceling the printing operation, and a printing operation canceling means G for performing the six-set printing operation H in response to the space key operation 8' performed again after the printing operation is canceled.

[Function] In the electronic typewriter with a spell check function configured as described above, in the word 1 mode, when the space key is operated after inputting one word, the spell check process for that word is executed. If the word is correct, the word is printed as is, and if it is incorrect, it is not printed. Then, when the space key is pressed again, the corresponding word is printed out unconditionally.

Further, in another invention, when the space key is operated on the right margin position in the [right alignment] mode, the spelling of the word adjacent to the left is checked.

Then, if the word is correct, the words for one line are printed together in a right-aligned state. If it is incorrect, it will not be printed.

Then, when the space key is pressed again, one line of words including the corresponding word are printed out unconditionally.

[Example] An embodiment of the present invention will be described below with reference to the drawings.

FIG. 3 is a block diagram showing the general structure of an electronic typewriter with a spell check function. 16 in the figure is CPU1
7. ROM18. RAM1. '9 and various input/output boards are incorporated, and the keyboard 2 and display 9 are connected to this control unit 16. Based on various key signals from the keyboard 2, the 1III1 unit 16 operates a carriage motor 20 for moving the carriage 5, a print wheel motor 21 for rotating the print wheel 6, a print wheel motor 21 for rotating the print wheel 6, and a paper feed for printing paper 3 by rotating the platen 4. paper feed motor 22. Ribbon feed motor 23 for feeding the printing ribbon 8. Printing hammer 7 and buzzer 2
4 is driven and controlled.

Further, a spell check unit 25 is connected to the control unit 16 for checking the spelling of words inputted manually from the keyboard 2 .

This spell check unit 25 is composed of a type of microcomputer having a CPU 25a, a ROM 25b, and a RAM 25C, and when one word consisting of a plurality of character data is input from the control unit 16, it is stored in the RAM 25C. , it is determined whether or not each character data constituting the word is correct by comparing it with the correct word read from the dictionary memory 25d. Then, the spell check result is sent back to the control unit 16.

As shown in FIG. 4, the RAM 19 contains each mode flag indicating which mode is currently selected using the selection key 14, as well as spelling errors detected during spell check processing executed by operating the space key. A flag area R1 that stores flags such as an error detection flag as an error detection memory indicating that an error has been detected, a carriage position counter R2 that counts the carriage position i+1tcp that indicates the character input position in one line, and a key manually input 1. One line buffer R3 that stores each line of character data corresponding to the carriage position ICp (print position @), left margin key 15a
A margin position memory R4 and the like are formed to store the left margin position [LM and right margin position 118M set by the right margin key 15b.

The one-row buffer R3 is configured as shown in FIG. 5, for example. That is, each movable carriage position of the carriage 5 from Cp-1 to CI)-E is indicated by the carriage position Cp of the carriage position counter R2.
An area for storing each character data is formed for (each printing position). Then, for example, by the left and right margin position setting operation performed before the start of the typing operation,
The storage area for each character data in one line is CI) -LM
(left margin position) to Cp-RM (right margin position It).

Then, the carriage position of the one-line buffer R3 (print position I
I) Each character data of CDs from CD-Ds to Cp-De is displayed on the display 9. Normally, the display section in the one-line buffer R3 displayed on this display I9 is at the carriage position I.
It moves following the movement of Cp.

Then, the power of this electronic typewriter with a spell check function is turned on, and a series of initial processes such as clearing each memory including each flag in the flag area R1 of the RAM 19 and initializing each input/output board are completed. When a key operation is performed on the keyboard 2 after the keyboard 2 enters a typing operation ready state, the all 1 section 16 is programmed to execute key manual processing according to the flowchart shown in FIG.

In FIG. 6, when the flowchart is started and a key operation is executed on the keyboard 2 at Pl, after confirming that the type mode flag in the flag area R1 of the RAM 19 is cleared to O, the input key is Understand the types of.

If the selection key 14 is in the [spell check] mode at P2, the value of the spell check flag in the flag area R1 is inverted. Then, in P3, the reversed spell check flag is set to 1, and if it is set to 1, the previous key operation of the selection key 14 is determined to be a key operation for setting the [spell check] mode. , a message indicating that the spell check mode has been set is displayed on the display section 9 at a certain time.

Further, if the spell check flag is cleared to 0 at P3, it is determined that the previous selection key 14 was operated to cancel the [spell check] mode, and the display section 9
Displays a message that spell check mode has been canceled.

In addition, if the key operation on the keyboard 2 at P4 is a key operation with a character key that involves printing, such as the alphabetic key 10 or the numerical key 11, the corresponding character data is stored in the carriage position counter R2 in the one-line buffer FR3 of the RAM 19. It is stored in the area indicated by the carriage position Cp. When the character data is stored, the corresponding character is displayed on the display 9 according to the procedure explained in FIG. And the carriage position counter R
2nd carriage position! Increase ICp by 1. after that,
The error detection flag in flag area R1 is reset to O.

Further, when the space key 12 is operated at P5, a space key process to be described later is executed at P6.

Furthermore, if the key input at P5 is not the space key 12, manual key processing corresponding to each of the other function keys input at P7 is executed. For this key manual processing, the left and right margin positions 11LM and RM are used for each margin key 15a.

This also includes the task of setting the margin position memory R4 in step 15b. When the function key processing of P7 is completed,
The error detection flag in the flag area R1 is reset to 0.

FIG. 7 is a flowchart showing the space key processing at P6 in FIG.

That is, the flowchart is started and flag 1ifa is set at P8.
! It is confirmed that the spell check flag in R1 is set to 1, and the setting state of the word mode flag in the flag area R1 is checked in P9.

If it is set to 1, the electronic typewriter is in Word 1 mode, so proceed to Plo.

Then, it is confirmed that the carriage position Cp is located to the right of the inputted word, and the state of the error detection flag in the flag area R1 is checked using Pll. If the error detection flag has been cleared to 0, the process advances to P12, and the word located to the left of the carriage position ICp in the one-line buffer R3 is read out.
The word is sent to the spell check unit 25, and spell check processing is performed on the word.

When the PI3 receives a response indicating that there is a spelling error from the spell check unit 25, it sets the error detection flag in the flag area R1 to 1. Then, the buzzer 24 is made to sound for a short period of time without executing the printing operation for the corresponding word.

Note that when the PI3 receives a response indicating that there are no spelling errors from the spell check unit 25, the process advances to the PI3 and executes the normal printing operation for the corresponding word in the word 1 mode. Then, a space (space code input) operation is executed to advance the carriage position by one.

When the printing operation in PI3 is completed, the error detection flag in flag area R1 is reset to O.

Also, if the error detection flag in flag area R1 has already been set to 1 in Pll, the current space key operation will cause a spelling error to occur in the word to the left of carriage position lCp, and the error will be corrected. It is determined that the space key operation was executed again without In this case, since there is no need to perform a spell check, the process directly advances to P14 and prints the corresponding word.

Furthermore, if the carriage position ICD is not located to the right of a word in Plo, it is determined that the space key has been operated consecutively to intentionally create a blank space in the sentence. In such a case and when the spell check flag is cleared to O at P8, there is of course no need to perform a spell check, so the process advances to PI3 and the printing operation is immediately executed.

Furthermore, if the word mode flag in flag area R1 is cleared to O in P9 and the right alignment mode flag is set to 1 in PI3, it is determined that this electronic typewriter is in the [right alignment] mode. do.

Then, in PI3, the carriage position ICp is at the light margin level! If the word is located on the IRM and there is a word to the left of the carriage position Cp in Plo, the error detection flag is set to O in Pll to indicate the necessity of spell checking for the last word in the [align right] mode operation. Confirm that it has been released.

Then, in P12, a spell check is performed on the corresponding word.

If there is no spelling error in the PI3, the normal right column printing operation in the [right alignment] mode is executed in the PI3. In other words, the one-line buffer R3 is moved so that the right end of the word on the nepalite side in the one-line buffer R3 is located at the right margin position RM.
After automatically adjusting the spacing between each word stored in , all words are printed.

Note that if the carriage position Cp is at the light margin position on the IRM and there is no word to the left of Plo,
If the error detection flag has already been set to 1 in , there is no need to perform a spell check, so the process immediately proceeds to PI3 and executes the right column printing operation.

Further, if the carriage position Cp is not located on the write margin position RM in P16, the process advances to P17. P17
If there is a word on the left, a spell check process is executed for the word in P18, and a space process is executed in PI3. In other words, the space code is stored in a one-line buffer R
Store in 3. Note that if there is no word on the left in P17, space processing is directly executed in PI3.

In the electronic typewriter with spell check function configured as described above, after turning on the power and before starting typing operation, the operation mode can be changed between the [spell check] mode and the [word] mode by key operation of the selection key 14. Set to combination mode. Then, press the left margin key 15a and the right margin key 15b to select the margin position memory R.
4, each margin position LM and RM are set.

Then, alphabetic key 10 of keyboard 2. Character keys such as numeric keys 11 and space key 12 are operated to input text in sequence. In this process, each time the space key 12 is operated after the manual key operation for one word is completed, a spell check is executed for the previous word. Then, if no spelling error is detected, the corresponding word is printed. When a spelling error is detected, a warning sound is generated by the buzzer 24 and the corresponding word is not printed. therefore,
When the typist hears the warning tone, the typist presses the backspace key, for example, to change the carriage position gICp in the display 9.
is moved back to the position of the erroneous character, and then the erroneous character is corrected. Note that it is also possible to ignore this correction operation.

In this case, if the space key 12 is pressed again, the incorrect word will be printed.

In this way, if an erroneous word is detected in the spell check, the word will not be printed, so the typist can easily correct the erroneous word. Furthermore, if necessary, it is possible to intentionally ignore the error and print the corresponding word. Therefore, the operability of the electronic typewriter can be greatly improved.

In addition, after turning on the power and before starting a typing operation, set the operation mode to a combination mode of [spell check] mode and [align right] mode by operating the selection key 14, and then press the character key on the keyboard 2 and the space key. Even in the process of inputting sentences one by one using the keys 12 and storing them in the one-line buffer R3, the spelling of the word to the left of the space is checked every time the space key is operated.

If the carriage position mcp is located on the light margin position @RM when the keystroke of the last word in one line is completed, if you press the space key 12 in this state, the spell check of the last word will be performed. 1 line buffer R3
Execute right column printing operation for all words in . in this case,
If there is no spelling error in the word, the right column printing operation is executed as is, but if a spelling error is detected, the right column printing operation is not executed. Therefore, since the erroneous word is not printed, the erroneous word can be easily corrected as in the above-mentioned [word] mode.

Note that even in this [right alignment] mode, by operating the space key again after a spelling error has been detected, it is possible to execute the right column printing operation with the erroneous word still included.

[Effects of the Invention] As explained above, according to the electronic typewriter with a spell check function of the present invention, if a spelling error is detected by operating the space key in the [Word] mode or the [Align right] mode, the The operation following the spell check process is temporarily stopped.

Therefore, the word error correction operation can be easily performed, and the operability of the electronic typewriter as a whole can be greatly improved.
