On the carriage 18 are a printing ribbon 23 and a type wheel 24.
, and a printing hammer 25 are fixedly installed, and these printing devices print on the printing paper 16 and the auxiliary printing paper 17 on the platen 13.

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

In FIG. 2, main first and second printing control means,
A central processing unit (hereinafter referred to as host CPU) 31 serving as a comparison means operates based on a control program written in a program memory 32 consisting of a read-only memory (ROM), and operates by pressing the space key 4 and the character key. Input an on signal based on the on operation of various keys such as 5-, input a character based on the input from the character key 5 (a-in-law), and respond to the on signal from the space key 4 and press the character key first. Based on the operation in step 5, the input character set is determined as one English word.

The text message pad 33 is a random access memory in which English sentences created using the character keys 5, space key 4, etc. are stored. Dictionary memory 34
is a read-only memory (ROM) in which English word data of a large number of English words is stored.

First sub-central processing unit (hereinafter referred to as first slave CPU)
35 reads the English word data stored in the dictionary memory 34 and transfers it to the host CPU 31 in response to a control signal from the host CPU 31. A second sub-central processing unit (hereinafter referred to as second slave C)
A PU (referred to as PU) 36 drives and controls the LF motor 15 and carriage drive motor 22 based on control signals from the host CPU 31.

Third sub-central processing unit (hereinafter referred to as third slave CP)
37 drives and controls a wheel drive motor 38, a ribbon drive motor 39, and a hammer drive solenoid 40 based on control signals from the host CPU 21. The wheel drive motor 38 is mounted on the carriage 18 and rotates the type wheel 24 to select a predetermined printing element. Ribbon drive motor 38
is similarly provided on the key jt ridge 18, and is configured to feed and drive the printing ribbon 23. Further, the hammer driving solenoid 40 drives the printing hammer 25 and hits the selected printing element to print characters, etc. on the printing paper 16 and the auxiliary printing paper 17.

When the print execution key 9 is turned on while the check execution key 7 is on, the host CPU 31
In response to the ON signal, each English word data of the English text input using various keys such as the character key 5 and the space key 4 stored in the text memory 33 is sequentially read out and spell checked. Spell checking is performed by individually comparing the successively read English words "an" with a large number of English word data stored in the dictionary memory 34.

That is, the host CPU 31 transfers the English word data stored in the dictionary memory 34 to the first slave CP Ll.
, 35, the text memory 33
Search for English word data that matches the English word read from. Then, when there is matching English word data, the boss 1 to CPU 31 determine that the input English word is spelled correctly, and immediately print the English word at a predetermined printing position on the printing paper 16 using the second and third units. Slave CPU36,3

．． 39 and the hammer drive solenoid 40. Therefore, when the spellings of the English words sequentially read from the text memory 33 are correct, the read arrow wheels n are sequentially printed on the printing paper 16.

On the other hand, when there is no matching English word data, the host CP
U31 judges the English 1 g to be a misspelling. At this time, the host CPtJ31 stops the printing operation on the printing paper 16, and executes the printing processing operation to print the English word determined to be misspelled on the auxiliary printing paper 17.

The printing process operation on the auxiliary printing paper 17 is first performed by the carriage 18.

to be printed. .

In this printing processing operation, the host CPU 31 controls the IF motor 15 so as not to drive ωJ, and determines that the arrow δ11 is a misspelling on the printing line on the auxiliary printing paper 17 corresponding to the printing line that should originally be printed. The English words that have been written are now printed. J'-3, if there are misspellings of multiple days in one printing line of the printing paper 16, the multiple English words printed on the auxiliary printing paper 17 are printed on the same printing line of the auxiliary printing paper 17. 8WD f) J motor 22.38.3
9 and the hammer drive solenoid 40.

When the printing processing operation on the auxiliary printing paper 17 is completed, the host CPU 31 executes the correction processing operation. The correction processing operation is performed by inputting a correctly spelled English word by operating the character keys 5 and space key 4, and the host CPU 31 first records the correct spelling in the text memory 33. , 1, which is determined to be a misspelled word, is replaced with a newly input corrected English word. Then, the host CP (J31) checks the spelling of the corrected English word again in the same way as above and checks whether the spelling is correct.
After the English word determined to be misspelled is printed at the print position where it would have been printed if it were determined to be correctly spelled, the next English word is spell checked. On the other hand, if it is not correct, the same operation as above is repeated again.

This printing operation is performed by the host C and PU 31 via the second and third slave CPUs 36 and 37 in the same manner as described above.
This is done by controlling the drive motors 22, 38, 39 and the hammer drive solenoid 40.

In addition, if you want to enter an English word that has been determined to be a misspelling and was printed on the auxiliary printing paper 1A as the correct spelling, operate the passkey 8, and the host CPU 31 will respond to the After the English!1'i word is selected and printed at a predetermined printing position on the printing paper 1G, the spelling of the next English word is actually checked.

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

Now, in a state where the English text entered using the character key 5, space key 4, etc. is stored in the text memory 33, set the check execution key 7 to the on state/[After turning on the print execution key 9 (step 1) Then, in response to the on signal, the host CPU 31 determines that the check execution key 7 is in the on state (step 2), and reads out the first English word data of the English sentence stored in the text memory 33. 3) Perform a spell check (Step 4). Then, the host CPU 31 has a dictionary menu,
The arrow wheel 5R data stored in 34 is transferred to the first slave CP.
The English word data that matches the English word read out from the text memory 33 is searched for sequentially through U35.

If there is matching English word data, the small strike CPU 31 determines that the input English word is correctly spelled (step 5).
), and outputs a control signal to the second and third slave CPUs 36, 37 to drive and control each motor 15, 22, 38, 39 and the hammer drive solenoid 4o to drive the carriage 1.
8 to the specified printing position on the printing paper 16 (Step 6)
Let me do that! lj Print the edict (step 7). After printing, the host CPU 31 determines whether all the English words in the English sentence stored in the text memory 33 have been read out and the spell check has been completed (step 8), and then reads out the remaining English words from the text memory 33 and spells them again. Execute the check (step 3).

Then, when the spelling of the English words sequentially read from the text memory 33 is correct, the read English words are sequentially printed on the printing paper 16.

On the other hand, when there is no matching English word data, the host CP
U31 misspelled the English word as 'I'll f
t catty (step 5). At this time, host CP IJ3
1 stops the printing process operation on the printing paper 16, and the second
The carriage 18 is driven to the auxiliary printing paper 1 by controlling the carriage drive 22 through the slave CPIJ 36.
Move to the printing position of 7 (step 9) σ Continuously, the small stroke CPtJ31 is moved to the second and third slave CPU36,
37, the drive motors 22, 38, 39 and the drive solenoid 40 are driven to print the English words determined to be misspelled on the auxiliary printing paper 17 (step 1).
0).This printing position is set when the host CPIJ31 is LF.
Since the motor 15 is controlled not to be driven, the print line is printed on the print line that corresponds to the print line that should originally be printed on the print paper 16. Then, when the misspellings are printed,
The boss CPU 31 waits for a key operation for the English word t<city (step 11).

Therefore, the English words judged to be misspelled are printed on printing paper 16.
Instead of being printed on the auxiliary printing paper 17, the misspelled English words that were supposed to be printed on the printing paper 16 can be immediately WH'd.

In order to input the correct English 1 m, the predetermined character key 5 is converted (
Step 11), the host CPU 31 determines that the pass key 8 and space key 4 were not operated, but the character key 5 was operated (step 12.13), and the previously memorized English ( After rewriting each character of the 11th edict with the character corresponding to the operated character key 5 and storing it in the text memory 33 (step 14), the next character input is waited (step 15).Then, the English word is corrected. is completed and the space key 4 is operated (step 15), the host 1 to CPU 31 determines that the space key 4h has been operated (step 13) and spell-checks the corrected English word again (step 16). ).Then, when it is determined that the spelling is correct (step 5), the host CP
U31 drives and controls the carriage drive motor 22 via the second slave CPU 36 to move the carriage 18 to the printing position on the printing paper 16 (Il'l as the misspelling).
Move to 1C position (1C) where the IF/i Yakoura is supposed to be printed, and then zigzag at J (step 6). Next, host C
The PU 31 corrects the problem by driving the drive solenoid 40 and the drive solenoid 40 via the second and third slave CPUs 36 and 37.

After printing, the host Cl) 31 reads the next English word from the text menu 33 in the same manner as described above and executes the suberch T, tsuku again (step 3). Then, when the spelling of 芙1111过 sequentially read from the text memory 33 is correct, the read English words are sequentially printed on the printing paper 16.

In addition, when the passkey 8 is operated in the key operation "r" in step 11, the host CPtJ31 determines that the misspelled word is spelled correctly (step 12).Then, the host CPU 31 performs the same spelling as described above. Then, the carriage driving motor 22 is driven and controlled via the second slave CPU 36, and the carriage 18 is moved to the printing position on the printing paper 16 where the English word temporarily judged as a misspelling was to be printed (step 6).
Shun Zazeta, 2nd and 3rd slave CPIJ36, 37
The drive motors 22, 38, 39 and the drive solenoid 40 are driven to print the English words as they are on the printing paper 16 (step 7). After printing, the boss CPU 31 reads the next English word from the text memory 33 and performs spell check again in the same manner as described above.

Furthermore, when the print execution key 9 is operated with the check execution key 7 turned off, the host CPIJ 31 sequentially reads out each English word stored in the text memory 33 and prints it directly on the printing paper 16 without checking the spelling. (
Step 17).

In this way, in this embodiment, the English words of the inputted English sentence are sequentially checked for spelling, and if they are correct, they are printed one by one on the printing paper 16. When it is determined, printing of the English word on the printing w116 is stopped and printing is performed on the auxiliary printing paper 17, so that the misspelled English word can be immediately confirmed.

Moreover, the misspelled English words are not printed on the printing paper 16, and the corrected English words are printed with the misspelled words [! Since the 7i English words are printed at the positions where they should have been printed, clear English words without spelling mistakes can be printed on the printing paper 16.

Note that the present invention is not limited to the above-mentioned embodiment. For example, printing on the printing paper 16 may be stopped every time there is a misspelling, and the English word determined as a misspelling may be printed on the auxiliary printing paper 17. However, each English word written in the text memory 33 is spell-checked, but is printed directly on the printing paper 16 regardless of the result of the spell-check. and,
There are many misspellings in the English text printed on the printing paper 16,
If there is i71, when the printing portion of the misspelled English word is printed on the printing paper 16, immediately move the hair ridge 18 to the auxiliary printing paper 17 and write the misspelled word on the auxiliary printing paper 17. The determined arrow mark T; may be omitted from printing and executed.

Furthermore, in the embodiment described above, the spell check was performed on all the English sentences stored in the text memory 33, but when one English word is entered using the character key 5, the space key 4, etc., the spell check is performed immediately. If the spelling is correct, it is printed on the printing paper 16, and if it is a misspelling, it is printed on the auxiliary printing paper 17, and after correcting the spelling of that one English word,
The English sentence may be created by inputting the next new English word. Of course, the spelling is checked every time a line of English words are input, and if the spelling is correct, it is printed on the printing paper 1G, and on the other hand, if it is misspelled, it is printed on the auxiliary printing claw 17.
It may also be carried out by having it printed.

(Effects of the Invention) As detailed above, according to the present invention, it is possible to use an electronic typewriter equipped with a display that can only display a plurality of characters or late lines, or an electronic typewriter that is not equipped with a display. Informing the user of the spell check result in a very easy-to-understand manner increases the effect of C.1.
