Abstract

PURPOSE:To remove misprinting due to operator's malfunction by inspecting the correct spelling word of a word consisting of inputted characters by referring a dictionary and controlling the operation of document processing based upon the inspected result. CONSTITUTION:When a character key in an input part 1 is depressed, its corresponding code is inputted to an MPU 2 and the MPU 2 decides whether the inputted key goes the division of the word or not. When it is decided that the key is not the division of the word, key code data are converted into character code data and the data are stored in a sentence memory 4A. When it is decided that the inputted key is the division of the word, the MPU 2 segments the word from the memory 4A and inspects its spelling. Whether the word exists in a dictionary 3B in a ROM 3 or not is retrieved to decide whether the word is a correct spelling or not. When an incorrect spelling is decided, an alarm or the like is generated to the operator.

Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a document processing device that stores input character information, displays the content, and prints the information, and in particular has a function of checking for spelling errors in words. The present invention relates to a document processing device having a function of preventing the printing of misspelled words by using the following.

[Prior Art] Conventionally, in a document processing device such as an electronic typewriter, when checking for errors in word clutter during document input, the trigger for activating a function to determine whether the spelling of a word is correct or incorrect is as follows. This occurs when a character or key that is not included in a word is entered. For example, when a tab execution key is used as a function key such as a new line key, or a space key is input, the spelling of a word is checked.

[Problems to be Solved by the Invention] However, when the above-mentioned function key checks the spelling of a word, it may also start printing the input data, so it is difficult to check the spelling of a word with an incorrect spelling. There were cases where it was printed.

Even if the operator is alerted by an alarm to the incorrect spelling of the entered word, the word has already been printed, so the operator must first move the carrier to erase the incorrectly entered part. , subsequent corrections must be made, erasing cannot be achieved using non-erasable printing ribbons, and even if erasing is possible, erasing ribbons are consumed, operations are frequent, and the efficiency of document input is reduced. It was bad.

SUMMARY OF THE INVENTION An object of the present invention is to provide a document processing device that solves the above-mentioned problems and eliminates printing errors.

[Means for Solving the Problem] In order to achieve such an object, the present invention comprises a document storage means for storing character code information corresponding to input characters, and a collection of the character code information. A dictionary in which the spellings of words are recorded in advance, and a word consisting of the input characters is checked for correctness of the spelling of the word by referring to the dictionary, and document processing operations are controlled based on the inspection results. [Function] According to the present invention, when the spelling check of a word is started and the spelling of the word is incorrect, the input key that started the spelling check of the word is activated. By giving the operator an opportunity to correct the word before executing a function, it is possible to eliminate printing errors caused by operator error.

[Example] Hereinafter, the present invention will be described in detail with reference to the drawings.

As shown in FIG. 1, the document processing device according to the present invention includes a document storage means 101 that stores character code information corresponding to input characters, and a document storage means 101 that stores in advance spellings of words consisting of a collection of character code information. and a control means 103 that refers to the dictionary 102 to check whether the spelling of the word is correct or not, and controls the document processing operation based on the check result. shall be.

FIG. 2 shows the configuration of a document processing device according to an embodiment of the present invention. Here, 1 is an input unit in the form of a keyboard, for example, and inputs key code data corresponding to the pressed character key.
Output to Ptl (microprocessor) 2. 3 is l
It is a read-only memory (10M), and is composed of a control program 3A for the MPU 2 to control the entire device, a dictionary 3B for determining whether a word is spelled correctly, and the like. A RAM (Random Access Memory) 4 functions as a work memory for the MPU 2 and has a text memory 4A that temporarily stores character code strings etc. converted from key codes input from the input section 1.

5 is a display section in the form of an LCD (liquid crystal display), for example, and the text memory 4 A l! l) The character code string read from
Display is based on the control information of the control program 3A read out from the control program 3A.

6 is a printing unit, which prints the character code string read from the text memory 48 by MPtl2 into R[
Printing is performed based on the control information of the control program 3A read from 1M3.

Next, referring to the embodiment shown in FIG. 3 and the flowchart shown in FIG. 4, a text input process involving word spelling check according to the present invention will be described.

FIG. 3 is a schematic diagram illustrating the document display format displayed on the display unit 5 shown in FIG. 2. 7 indicates a state in which a text is being input, and this text has been stored in the text memory 4^, but has not yet been printed. The character input position is represented by a cursor displayed as a memory "-". 8
indicates that the line feed key has been input in state 7,
The symbol "-" indicates that the line feed key has been input,
Printing due to the input of the line feed key is not being executed. 9 shows a state in which the word "tenis" is corrected to "tennis" from the state of 8.

FIG. 4 is a flowchart illustrating a text input process involving word spelling check according to the present invention, and 5tN511 indicates each step. In this embodiment, in a document processing device such as an electronic typewriter, an input method in which printing is performed line by line will be explained as an example; The present embodiment is also applicable when using this method.

First, in step Sl, when a character key on the input section 1 is pressed, a code corresponding to the pressed key is sent to the MPU.
2 is input. Next, the process proceeds to step S2, and the MPU 2 determines from the key code data whether the input key is a word break.

Keys that do not delimit words include character keys that are constituent molecules of words, and keys that delimit words include function keys other than character keys, such as the tab execution key, line feed key, and space key.

In step S2, if the MPt 12 determines that the input key is not a word break, the process proceeds to step S3, where the input key code data is converted into character code data and stored in the text memory 4A. At the same time, in step S4, the MPU 2 sends display data corresponding to the character code data to the display unit 5 to indicate to the operator that the key has been input normally, displays the data, and performs the next key input. wait.

In step S2, if it is determined that the input key is a word break, the process advances to step S5, and the MPU2
extracts a word from the sentence meaning memory 4^ and checks its spelling.

Next, the process proceeds to step S6, where the MPII 2 determines that the character string input before the key that separated words this time is one word from the character string input after the key that separated words last time, and A search is made to see if the word exists in the dictionary 3B in the ROM 3, and it is determined whether the word is spelled correctly.

In the example shown with reference numeral 8 in FIG.
“, and when these keys are input, the MPU2 outputs the word “I”.
”, “play”, and “tenis” are extracted.As a result of the word spelling check in step S6, it is determined that the words “■” and “play” are spelled correctly, and the word “tenis” is incorrectly spelled. Suppose that it is determined that the word “I”.

If it is determined that the spelling is correct, such as "play", the key that delimits the word is executed in the same way as in the normal case in step Sll. Then, the process returns to step St and waits for a key input. Number 8 in Figure 3
In the example shown, the word separator is the space key “
-'', the character code data is stored in the text memory 48, and displayed on the display section 5.

On the other hand, if it is determined in step S6 that the word is misspelled, such as the word "tenis", the process proceeds to step S7;
It issues a warning to the operator using an alarm or the like, and displays the keys that separate the words. The MPU 2 stores the input key code data in the work area of the RAM 4.

In the example shown by reference numeral 8 in FIG. 3, the line feed key "-" is a word delimiter key, and is being displayed. From this state, the operator determines whether to correct the spelling of the word or execute the key without making corrections, and then proceeds to step S.
At step 8, key input is performed.

Then, the process proceeds to step S9, and if the operator checks the display and wishes to continue the input operation in the current input state, the process proceeds to step S9, and inputs a function key that prompts the operator to execute the key that separated the words. and continue the following operations.

On the other hand, when correcting a misspelled word, input a function key other than the function key that prompts the execution of the key that separated the word in step S8, and proceed to step 510 based on the judgment in step S9, and press that key. Execute and make corrections.

This correction method includes moving the cursor to the corrected part, deleting the incorrect part, and re-entering the correct spelling, or using Dictionary 4R to find a candidate word with an approximate spelling from the incorrectly spelled word. There are methods to find it and automatically replace it. After the operator completes the word correction work, a function key is input in step s8 to prompt the execution of the key that delimits the word, and the key that delimits the word is executed in step 511. In the example shown with reference numeral 8 in FIG. 3, the word "tenis" is corrected to "tennis", resulting in the state shown with reference numeral 9 in FIG. When a function key that prompts the execution of a key, such as a "continuation key", is input, a new line key is executed. If you are inputting using the print-by-line input method, print that line and start a new line; if you are inputting using the display-only input method, move the cursor to the next line and input the next line and subsequent lines. Continue operation.

As described above, when an operator makes a misspelling of a word, by giving the operator an opportunity to correct it once, it is possible to correct the problem caused by executing the next function even though the operator understands that the spelling of the word is incorrect. Can be omitted.

With the above method, it is possible to correct misspelled words before the function key is executed, but if the execution of the function key that separated the words does not start printing, it is possible to correct the misspelled word before and after the function key is executed. one! The work method and amount of work for correcting $L words are almost the same. In either case, all that is required is to correct the unprinted data on the display.

Therefore, if the function key that separated a word does not start printing, the execution of the function key will not be stopped again, but the execution of the function key will be stopped only when the function key starts printing. is more practical.

Conversely, considering only the case where printing is started, the spelling of all words in the unprinted data is checked, and if a word with an incorrect spelling is found, printing is stopped and the operator is asked to confirm the word. The control structure may also provide an opportunity to correct the spelling.

[Effects of the Invention] As explained above, in the present invention, when 41 words with incorrect spellings are input, the operator is instructed to make corrections when it is determined that the input words are incorrectly spelled. Since the opportunity is provided, the effect is that misspelled words can be easily corrected on the display screen.
