PURPOSE:To obtain a document processor with a spell check function at which it is not necessary to provide a user dictionary memory, and by which it is not necessary to operate the maintenance of a memory backup mechanism or the registering operation of complicated words in the user dictionary memory. CONSTITUTION:The document processor with a spell check function operates the spell check of word data stored in a word buffer 23 by using a word dictionary memory 18 (S32). When the above mentioned word data are not present in the word dictionary memory 18 (S33: YES), whether or not the above mentioned word data are present or not in the same text is retrieved (S34). Then, in the case of the absence of the above mentioned word data, a buzzer 12 indicating a miss spell is rung (S36), and in the case of the presence, the buzzer is not rung, and the spell check of the next word data is operated.

Description

[Detailed description of the invention]

0001

[Industrial Field of Application] The present invention relates to a document processing device with a spell check function, and in particular, for words determined to be misspelled but used in the same document, a warning indicating that the words are misspelled is not issued. The present invention relates to a document processing device with a spell check function.

0002

2. Description of the Related Art Conventionally, document processing devices such as word processors and typewriters are equipped with a word dictionary memory, and a spell check is performed to determine whether each input word is stored in the word dictionary memory. Words that are not stored in the dictionary memory are treated as misspelled words, and a buzzer or the like is used to issue an alarm to notify the user of the misspelled word.

[0003] This type of document processing device usually has a writable memory in order to store (hereinafter referred to as registration) character strings such as words, abbreviations, and proper nouns that are not stored in the word dictionary memory. A user dictionary memory is provided, and spell checking is performed via both dictionary memories to prevent misspellings caused by proper nouns and the like.

By the way, in a document processing device equipped with a user dictionary memory, a memory backup mechanism using a battery or the like is installed to prevent data stored in the user dictionary memory from being lost, or the capacity of the document memory is reduced. A storage area is reserved for user dictionary memory.

By the way, a document processing device equipped with a word dictionary memory or a user dictionary memory is usually provided with a registration key on the keyboard for registering misspelled words in the user dictionary memory. When inputting a document while performing a spell check, if a misspelled word is detected during input and the operator wants to register the misspelled word in the user dictionary memory, the operator operates a registration key.

[0006] In general, spell checking processing is often slower than character input processing, and a plurality of words are input after the word being spell checked. In this state, if a word determined to be misspelled is to be registered in the user dictionary memory, the following key operations are performed. That is, the user interrupts the input operation, operates the cursor movement key to point the cursor to the word determined to be misspelled, and operates the registration key to register the word in the user dictionary memory. Furthermore, the cursor movement key is operated to move the cursor to the input position at which the input was interrupted, and the input operation is continued.

[0007]Furthermore, when spell-checking all the document data already stored in the document memory, if the detected misspelled word is a proper noun, the registration key is operated for this proper noun, and the user dictionary I am trying to register it in memory.

[0008]

[Problems to be Solved by the Invention] However, the above-mentioned conventional device has various problems such as the memory backup mechanism increases the product cost and requires the user to perform extra operations such as replacing the battery. Loss of data due to a drop in the power supplied by the battery becomes a problem. Also,
For example, for words such as proper nouns that do not need to be corrected or treated as misspelled words, if the registration process is not performed, a buzzer indicating a misspelled word will sound each time the word is entered, which will be troublesome for the operator. . Furthermore, when registering the proper noun in the user dictionary memory, it is necessary to operate a complex combination of cursor movement keys and registration keys, resulting in a problem that the registration operation in the user dictionary memory becomes complicated.

Moreover, if the operator does not know that a user dictionary memory is provided or does not know how to register in the user dictionary memory, the warning buzzer will repeatedly sound each time a proper noun is input. There is a problem with doing so.

The present invention has been made to solve the above-mentioned problems, and eliminates the need for providing a user dictionary memory, and eliminates the need for maintaining a memory backup mechanism and registering complex words in the user dictionary memory. It is an object of the present invention to provide a document processing device with a spell check function that is not necessary.

[0011]

[Means for Solving the Problems] A document processing device with a spell check function according to the present invention, as shown in the functional block diagram of FIG. 1, includes an input means for inputting characters, symbols, and various commands; A document memory that stores document data input from the input means, a word dictionary memory that stores spelling information of a large number of words, and a word dictionary memory that receives word data input from the input means and processes the words through the word dictionary memory. a spell check means for performing a spell check; a word search means for searching the input word for the same word in the document memory; and an alarm prohibition unit that prohibits the alarm unit from operating if the word search unit finds that the same word exists in the document memory for a misspelled word determined to be misspelled by the spell check unit. equipped with the means.

0012

[Operation] In the document processing device with spell check function of the present invention having the above structure, each word inputted by the input means is stored in the document memory. The spell check means performs a spell check on the input word based on the word dictionary memory and the document memory. here,
When the same word does not exist in both memories, the word search means searches whether or not the same word exists in the document memory, and if the same word does not exist, the alarm means warns the operator that there is a misspelling. If the same words exist, the alarm prohibition means prohibits the alarm operation of the alarm means.

The control device C is composed of a CPU 16, an input/output interface 14 connected to the CPU 16 via a bus 15 such as a data bus, ROMs 17 and 18, and a RAM 20.

The program memory of the ROM 17 includes a control program for controlling the display mechanism DM and the printing mechanism PM in accordance with code data input from the keyboard 3;
A control program that stores the code data in the text memory 22 and word buffer 23, a cursor movement control program that moves the cursor according to the operation of the cursor movement keys, and an initial setting processing control that initializes the printing mechanism PM etc. immediately after power is turned on. Contains programs, spell check control programs, etc.

[0021] The spell check control program includes:
A spell check processing control routine for searching the ROM 18 and text memory 22 for an input word and executing spell check processing is stored.

[0022] The ROM 18 (hereinafter referred to as word dictionary memory) contains the following information for checking the spelling of English words.
For example, spelling data for approximately 70,000 words is stored in alphabetical order, similar to a normal dictionary.

Since the spell check process is a well-known and common process, it will be briefly explained. For each word input from the keyboard 3 and sequentially stored in the word buffer 23, a large number of spell check processes stored in the word dictionary memory 18 are checked. It compares words with each other to check whether the spelling is correct or incorrect.

The text memory 22 can store a plurality of document data groups, and when in the memory writing mode, they are stored at a preset document position, or at a selected desired position when in the editing mode. Data is stored or various editing processes are performed at the position of the document according to code data input from the keyboard. This text memory 22 constitutes the document memory of the present invention.

The word buffer 23 stores word data for one word input from the keyboard in the spell check mode.

The flag memory 24 stores flag data of a spell check mode flag F1 that is set (data is "1") when the spell check mode is in effect and reset (data is "0") when the spell check mode is released. be done. Further, the RAM 20 is provided with various types of memories, counters, pointers, etc. for temporarily storing the results of calculations performed by the CPU 16, as required.

Next, the spell check control performed by the control device C of the electronic typewriter 1 will be explained based on the flowcharts shown in FIGS. 4 and 5. FIG. 4 is a flowchart showing the main control routine, and FIG. 5 is a flowchart showing the spell check processing control routine. Note that the symbol Si (i=1, 2, 3, . . . ) in the figure indicates each step. When the electronic typewriter 1 is powered on, the main control routine shown in FIG. 4 is started, and general initial settings such as setting the document data input mode and clearing each memory 22 to 24, Initial settings of the printing mechanism PM, such as setting the origin position of the carriage of the printing mechanism PM and the origin position of the daisy wheel, are executed (S1).

Next, the writing mode to the text memory and the editing mode are selected using the keyboard 3 (S2). When the operator operates the write mode key (S3: Yes), the process of inputting the document name using 10 on the liquid crystal display is performed (S4), and then the input screen is displayed on the liquid crystal display 10 and the data is stored in the memory. Shift to write mode (S5).

On the other hand, if the edit mode key is operated instead of the write mode key (S3: No) in the key input (S2) (S6: Yes), the document name stored in the text memory 22 is displayed on the liquid crystal display. 10 are sequentially displayed, and a process of selecting a desired document from among them is executed. Here, when the target document is selected (S7), the selected document is read from the text memory 22 (S8).
), the document data is displayed on the liquid crystal display 10, and the mode shifts to editing mode (S9).

Note that when the input key input is not a write mode key or an edit mode key (S2: Yes
, S3: No, S6: No), after the alarm process is executed and the buzzer sounds (S22), the key input process (S
Move to 2) to prepare for the next key input.

The main control that has shifted to the write mode or edit mode basically performs the same processing and shifts to key input processing (S10). Here, when the end key of this control is input (S11: N0, S21: Yes), the end process is performed (S23), and the first key input process (S
Step 2) prepares for writing or editing a new document.

[0032] If a key other than the end key and the character key is input (S11: No, S21: No), various processes based on the key input are executed (S22), and the process returns to the key input process (10). to prepare for the next keystroke.

If a character key is input (S11: Yes), the memory capacity of the text memory 22 is checked (S12), and the amount of code data stored by this key input is determined by the amount of code data stored in the text memory 22. If the capacity is exceeded (S12: No), alarm processing is executed (S20), and after the buzzer sounds, key input processing (
The process moves to S10).

If the amount of code data to be stored does not exceed the capacity of the text memory 22 according to the memory capacity check (S12: Yes), character input processing is performed (S12: Yes).
13). When the character input process is completed, the flag memory 24
The flag F1 is checked based on the contents of the flag F1, and if it has been reset and the spell check mode is not set (S14: No), the process returns to S10. Here, if flag F1 is set (S14: Y
es), the spell check processing control routine shown in FIG. 5 is executed.

If a key other than the separator key is operated when this spell check processing control routine is started (
S30: No), this spell check processing control routine ends and returns to the main control routine, but when a word separator key such as space is operated (S30
:Yes), if in write mode, the word data of the last input word is stored in the word buffer 23, or if in edit mode, the word data of the input word in the text memory 22 is read out and the word data is stored in the word buffer 23. The data is stored in the buffer 23 (S31).

Then, a spell check process is executed on the word data stored in the word buffer 23 using the word dictionary memory 18 (S32), and it is determined that the same word as the input word indicated by the word data exists in the word dictionary memory 18. death,
If the input word is not a misspelling (S33: No)
, this spell check processing control routine ends and returns to the main control routine.

On the other hand, if the same word as the input word does not exist in the word dictionary memory 18 and the input word is misspelled (S33: Yes), the word data stored in the word buffer 23 is stored in the text memory 22. A search is performed to see if the same word exists in (S34
).

[0038] When the same word as the input word does not exist in the text memory 22 (S35: No),
The buzzer 12 sounds to warn you of a misspelling (S36
), this spell check processing control routine ends and returns to the main control routine. If the same word exists in the document memory (S35), the spell check process control routine ends without sounding the buzzer 12 by skipping S36 and returns to the main control routine.

Note that the execution of S32 by the control device C corresponds to the spell check means of the present invention, the execution of S34 of the control device C corresponds to the word search means of the present invention, and the execution of S32 of the control device C corresponds to the spell check means of the present invention.
The skip number 6 corresponds to the alarm prohibition means.

As explained above, the electronic typewriter 1 of this embodiment automatically searches for the presence of words in the same document that are the same as words determined to be misspelled, such as proper nouns and abbreviations. , if it does not exist, the buzzer 12 will sound to warn you of a misspelled word, but if it does exist, the buzzer 12 will not sound and the next word will be spell-checked, so for the second and subsequent inputs. operates as if it were equipped with a user dictionary memory, allowing users to smoothly input documents while checking spelling without causing confusion for the operator.

The present invention is not limited to the above-mentioned embodiment, and various changes can be made without departing from the spirit thereof.

For example, in the spell check processing control shown in FIG. 5, S40 is added and changed between S35 and S36 as shown in FIG. If there are more than 1, the buzzer 12 may not sound by skipping S36.

That is, if the word to be spell checked is in the text memory 22 (S35: Yes) and there are three or more such words, the word is not determined to be a misspelled word (S40: Yes), and S36 This spell check processing control routine ends without sounding the buzzer 12 and returns to the main control routine.

On the other hand, if the same word does not exist (S35
:No), and if there are two or less (S40:
No), it is judged as a misspelling and the buzzer sounds (S36
), this spell check processing control routine ends and returns to the main control routine.

Therefore, by the control shown in FIG. 6, the buzzer 12 does not sound for frequently used words such as proper nouns, and the buzzer 12 sounds for simple misspellings to alert the operator.

The value determined in S40 of spell check processing control may be "2" or may be "4" or more.

It goes without saying that the present invention can be applied to various document processing apparatuses, such as electronic typewriters and word processors for various languages, which are equipped with a word dictionary memory and capable of spell checking.

[0048]

[Effects of the Invention] As is clear from the above explanation, according to the document processing device with spell check function according to the present invention, when a word such as a proper noun or an abbreviation exists in the same document, , alarms indicating misspellings are prohibited, eliminating the need for a user dictionary and eliminating the need for complicated operations such as registering words such as proper nouns and abbreviations in the user dictionary, greatly improving operability. .
