An input key for inputting in units, a text memory for storing English words inputted by the input key, and a display for displaying a limited number of characters or lines; 6. An electronic typewriter comprising a print control means for driving the printing device to print the English words stored in the text memory on the printing paper in response to the operation of the print execution key. a dictionary memory storing word data; a spell check execution key for checking the spelling of each English word stored in the text memory; and a spell check execution key for storing data in the text memory in response to an operation of the spell check execution key. a comparing means for comparing and determining each English word data stored in the dictionary memory with the English word data stored in the dictionary memory; and a comparing means for comparing and determining each English word data stored in the dictionary memory; reading means for reading out a misspelled word from the text memory along with the English words before and after the English word; and displaying the misspelled English word read by the reading means and the English words before and after it on the display device. The gist of the system is that it is equipped with a control means.

(Function) With the above configuration, in the spell check mode when the spell check execution key is turned on, the means for comparing the arrow wheel 8B inputted by the input key and stored in the text memory with the English word data stored in the dictionary memory. Compare and judge. When the comparing means determines that the English word does not exist in the English word data in the dictionary memory, the reading means reads out the English word as a misspelling from the text memory, and further reads the misspelled English word and the English words before and after it. Display the word on the display device.

(Embodiment) An embodiment embodying the present invention will be described below with reference to FIGS. 1 to 3.

In FIG. 1, an electronic typewriter 1 has shift keys 3. Various keys such as a space key 4 and a large number of character keys 5 as input keys are provided. When the character key 5 is operated, various character data such as alphabets or numbers corresponding to the character key 5 are selected and input. On the left side of the input board 2 are a print execution key 〇, a spell check execution key 7 and a pass key 8.
However, a return key 9 is also provided on the right side.

The print execution key 6 is used when you want to print, the spell check execution key 7 is used when you want to check the spelling of an English word input using the character keys 5, etc., and the passkey 8 is used when it is determined that there is a misspelling as described later. The return key 9 is used when inputting an English word as it is as an English word with the correct meaning, and the return key 9 is used when it is desired to change the line of a sentence.

A display device 10 is provided at the center position on the rear side of the input board 2, and characters input using the character keys 5 are sequentially displayed, and the display device filff10 displays 24 alphabetic characters. A printer device 11 as a printing device is provided on the rear side of the input board 2, and printing is performed when the print execution key 6 is turned on and the spell check execution key 7 is turned on.

Next, an electric circuit built into the electronic type-like 1 configured as described above will be explained.

As shown in FIG. 2, there are printing control means and comparison means.

Central processing unit (as reading means and display control means)
(hereinafter referred to as CPU) 13 is read-only memory 1
The random access memory 15 (hereinafter referred to as ROM) operates according to the control program written in the random access memory 15 (hereinafter referred to as ROM).
RA, I'vl). Space main - 43 character keys 5. Input an on signal based on the on operation of various keys provided on the input board 2, such as the printing actual 11 key 6, and press the character key 5.
Characters are displayed on the display device 10 based on input signals from the display device 10.

Further, in response to turning on the space key 4 (3z), the CPU 13 determines the character set previously entered manually based on the operation of the character key 5 as one English word.

The dictionary memory 16 is a read-only memory (ROM).
'), and stores a large number of English word data used during spell checking. The text memory 17 is constituted by a random access memory (RAM), and is configured to store English words input using the character keys 5 and the space key 4.

Further, the CPLJ 13 has a spell check function, and the spell check mode is set based on the ON operation of the spell check execution key 7, and the message '5PELL CHECK' is displayed on the display device 10 based on this spelling control program. .

When spell check mode is set, CP
U13 is the character key 5 and space key 4 in advance.
Each English word j) is read out in the order of the English words inputted earlier and stored in the text memory 17, and the read English words are stored in the text memory 16. It is determined whether the read English word exists in the dictionary menu 16 by sequentially comparing it with a large number of English words read out.

If there is a matching English word in the dictionary memory 16, the CPU 13 determines that the read English word is spelled correctly, and similarly performs a spell check on the next English word. When the spell check of all the English words stored in the text menu 17 is completed, '5PELL' is displayed on the display device 10 based on the tlJ control program.
The message “CHECKEN D” is displayed.

On the other hand, when there is no matching English word in the dictionary memory 16, the CPU 13 determines that the read English word is a misspelling, reads out the English words before and after the misspelled English word from the text memory 17, and corrects the misspelling. Both the English word and the English words located before and after it are displayed on the display device 10. Then, the CPU 13 displays the misspelled English word in a blinking manner to distinguish it from the English words located before and after it.

J3, in this example, the number of arrow wheels ';, f3 displayed before and after the misspelled English word is 11 in Ikko, but it is displayed according to the number of characters that can be displayed in the display 4ζ position 10. It is also possible to increase the number of English words.

Then, when i+'n among the misspelled letters is displayed blinking as described above, if you turn on passkey 8, C
Based on the ON signal of the passkey 8, the PU 13 determines that the misspelled English word is correctly spelled, and displays the display device 1.
Starting from 0, the display of the misspelled English word and the English words located before and after it are erased, and the spelling check of the next English word is subsequently performed.

Further, when a misspelled English word is blinking and the passkey 8 is not turned on, if the character key 5 is turned on again to correct the misspelled English word to a correctly spelled English word, the CPU 13 The English letters based on the ON signal are stored in the RAM 14, and the English letters are normally displayed on the display device 10. Then, when you turn on the space key 4 after operating the character key 5, the CPU 13 determines the character set stored in the RAM 15 as one English word, and performs the same spell check as above to confirm whether it is spelled correctly. , if it is correct, replace it with the misspelled English word in the text memory 17, and then,
The CPU 13 continues to check the spelling of the next English word.

When the character key 5 is turned on again to make a correction as described above and the corrected English word is spell-checked, if the corrected English word is again a misspelling, the CPU 13 The English words normally displayed on the n1j display device 10 are blink-displayed, and the passkey 8 or
Waits for character key 5 and space key 4 to be input.

Next, the operation of the electronic typewriter constructed as described above will be explained.

Now, when the power switch of the electronic typewriter 1 is turned on, the CPU 13 is set to the initial state. After turning on the print execution key 6, the controller waits for each second key on the input board 2 to be operated.

In a state where various key operations are performed, when a predetermined character key 5 and space key 4 are operated to input one arrow ml, it is determined that the character key 5 and space key 4 have been operated, and the operation is performed. 1 corresponding to the character key 5
1 English word is stored in the text memory 17, and thereafter the English word is inputted by key operation in the same manner, and this English word is stored in the text memory 17. When the spell check execution key 7 is not turned on, the on signal from the spell check execution key 7 is not input, so the CPU
It is determined that l3 is not in the spell check mode, and -C normal processing is performed based on the control program. (Step 1) Here, when the spell check execution key 7 is turned on, the spell check mode is set according to the on signal, and at this time, the CPU 13 displays "5PELL CIIEC" on the display device 10 based on the control program.
K'' message is displayed (step 3).

With this spell check shade set, the CPU
13 is a step 4) in which the English sentences input using the character key 5 and space key 4 and stored in the dex 1 to memory 17 are read out in the order of the English words inputted first. Roughly speaking, the CPU 13 sequentially compares the read English word with O against a large number of arrow wheels stored in the dictionary memory 16, and determines whether the read English word exists in the dictionary memory 16. It is determined whether or not (step 5).

Then, when the CPU 13 finds B in the matching arrow wheel in the dictionary memory 16 (step 6), the CPU 13 determines that the read English word is spelled correctly, and similarly checks the spelling of the next English word (step 6). 7). Then, when all the English words have been spell-checked and the spell-checking of the English words stored in the text memory 17 has been completed (step 8), a message "it 5PELL CHECK END" is displayed on the display device 10 based on the control program. Display the message (step 9).

On the contrary, the arrow wheel t+:”r that matches in the dictionary memory 16
If there is no such word (step 10), the CPtJ 13 determines that the read English word is a misspelling, reads out from the text memory 17 the words Fugetsu 4 n7j located before and after the misspelled English word, and replaces the misspelled English word with the misspelled word 1. ,n
and the English words located before and after i, together with the surface water device ff1l.
Display on o. Then, the CPU 13 displays the misspelled English word in a blinking manner to distinguish it from the English words located before and after it (step 11), and waits for the next key input.

Then, when the misspelled English word is displayed blinking as described above, when the passkey 8 is turned on (step 12), the CPU 13 determines that the misspelled English word is correctly spelled based on the on signal of the passkey 8. ,
The display of the misspelled English word and the English words located before and after it is erased from the display device 10, and the spelling of the next English word is subsequently checked.

Further, when a misspelled English word is displayed in a blinking manner, if the navigation passkey 8 is not turned on (step 13), the character key 5 is turned on again in order to correct the misspelled English word to a correctly spelled English word. Then, the CPU 13 stores the English characters based on the ON signal in the RAM 15 and normally displays the English characters on the display device 10 (
Step 14). Then, if you turn on the space key 4 after operating the character key 5 (step 15), c'
pU1-3 determines the character 1 stored in the RAM 15 as one English word, and performs the same spell check as described above (step 16). This spell check is performed to confirm whether the spelling is correct, and if it is correct (step 17), it is replaced with the misspelled English word in the text menu 17 (step 18). After this, the CPU 13 selects the next English word. Continue to check the spelling.

When the character key 5 is turned on again to make a correction as described above, and when the corrected English word is spell-checked, the corrected English word is again a misspelling (one step) In step 20), the CPυ 13 blinks the English words normally displayed on the display device 10 and waits for input of the pass key 8 or the character key 5 and space key 4.

When the spell check execution key 7 is turned on in this way, the spell check mode is entered, and the English words located before and after the misspelled English word are displayed on the display device M'710 along with the misspelled English word. The IfL position of the English word can be easily grasped, and it becomes easy to judge whether the misspelled English word is a true misspelling from the English words located before and after it.

Furthermore, in this embodiment, when a misspelled English word is determined, the passkey 8 can be turned on to leave it as it is. Therefore, in the case of an English word that is not stored in the dictionary memory 16, such as a proper noun such as a person's name, it is possible to take advantage of the English word.

It should be noted that the present invention is not limited to the above-mentioned embodiment, and the dictionary memory 16 may be of a cartridge type and may be removably attached to the electronic typewriter 1.

Effects of the Invention (Details above) As mentioned above, this invention not only allows spell checking to be performed easily, but also allows spell checking to be performed without misspelling even if the display device can only display multiple characters or a few lines. Since the word and the English words before and after the misspelled word can be displayed on the display device, it is easy to determine where the misspelled word is in the sentence, making spell checking easier. Can Qin excellent effect.
