FIG. 9 shows a memory map in the electronic typewriter of this embodiment. 5F from address (CLTBUF) of 300H (H indicates hexadecimal notation in RAM73 area)
The collect buffer 91 is provided up to the address FH, and the display buffer 92 is provided from the address 600H (LCDBUF) to the address 8FFH.

From 300H to 3FFH of collect buffer 91,
The code of the character entered by the key is stored in the print line and 400H
Addresses 4 to 4FFH are stored so that the upper part of the carrier address of the key-input character corresponds to address 500H to 5FFH, and the lower part of the carrier address of the key-input character respectively. With an ordinary electronic typewriter, the number of units that can be printed on one line is 600.
Since it is on the order of units or less, the high-order bit of the carrier address is a miss indication bit for indicating the first character of the misspelled word. When 1 is set in this bit, the corresponding word is misspelled, and when it is 0, it is not misspelled.

The codes of the characters displayed on the display device 4 are stored in the display buffer 92 at addresses 600H to 6FFH.
Character pitches are stored from 700H to 7FFH, and spell check flags are stored from 800H to 8FFH. The spell check flag is
This is a flag for blinking the cursor when the cursor is located at the beginning of the misspelled word on the display device 4.

Next, the operation of the electronic typewriter of the present embodiment thus constructed will be described with reference to the flow charts shown in FIGS.

First, in the main routine of FIG. 1, when a key is input, it is determined in step 101 whether it is a character or a space. If it is a character or a space, the amount of space is calculated in step 102 and printed in step 103. Alternatively, it is determined whether or not it can be moved. If it can be printed or moved, it is determined in step 104 whether it is a print character. If it is not a print character, the process jumps to step 107. If it is a print character, it is printed in step 105, the collector buffer 91 is created in step 106, and step 107 is entered. In step 107, the display buffer 92 is created, and in step 108 it is judged whether or not the spell check mode is set. Step 10 if not in spell check mode
Returning to step 1, the following steps are repeated. In the spell check mode, the pointer in the collect buffer 91 is searched in step 109.

Next, in step 110, it is determined whether the wordback flag is on, and if not, step 116
Fly to. If it is on, the composite character flag is turned off in step 111, and the spell counter is set to 0 in step 112.
Next, in step 113, the beginning of the word is searched for as a transmission pointer, (CLTBUF + (transmission pointer)) is stored in accumulator A in step 114, and it is determined in step 115 whether it is a checkable character. If it is not a checkable character, the process jumps to step 129, and if it is a checkable character, it is checked at step 116 whether the transmission pointer is equal to the pointer on the collect buffer.
If they are equal, the process proceeds to step 125, and if they are not equal, the process proceeds to step 117.

In step 117, it is determined whether or not the spell counter is 0. If it is 0, the process jumps to step 121. If not 0, the work area WORK is stored with the work pointer WORK minus the work pointer 1 address in step 118, and it is determined in step 119 whether the work area WORK is 0 or not. In this determination, whether there is a difference in space amount, that is, the overlap with the previous character is checked. If it is 0, the composite character flag is turned on in step 120 and the process returns to step 101. Work area WO in step 119
If RK is not 0, the process proceeds to step 121.

In step 121, the address at the time of transmission is stored as a transfer address, in step 122 (CLTBUF + (transmission pointer)) is stored in accumulator A, and in step 12
In step 3, the contents of accumulator A are sent to the spell check module. Next, in step 124, the spell counter and the transmission pointer are each incremented by 1, and the process proceeds to step 114 to execute the following steps.

In step 125, it is determined whether or not the spell counter is 0, and if it is 0, the process returns to step 101. If not 0, the carrier address-address of the transmission pointer is stored in the work area WORK in step 126, and it is determined in step 127 whether the value of the work area WORK is 8 or more. In this judgment, it is checked whether there is a space between the preceding character. If it is not 8 or more, there is no space, and the process returns to step 101. If it is 8 or more, there is a space, so the word back flag is turned on in step 128 and the process proceeds to step 129.

In step 129, it is determined whether or not the composite character flag is on. If it is on, the composite character flag is turned on in step 130 and then the process jumps to step 135. If the composite character flag is not on in step 129, the delimiter is transmitted in step 131, and the spell check is performed in step 132.
Next, in step 133, the mark pointer is searched, the mark is displayed on the LCD in step 134, and the process proceeds to step 135.
In step 135, the LCD is displayed and the process returns to step 101.

The spell check in step 132 of FIG.
This is performed in the spell check subroutine shown in the figure. In this spell check subroutine, step 20
In 1, it is determined whether there is a transmission from the spell check module side, and if there is a transmission, in step 202 a status indicating whether or not the spelling is correct, that is, whether or not there is a word with the corresponding spelling in the fixed dictionary and the user registration dictionary. To determine whether or not was returned. If the spelling is correct, 0 is stored in the accumulator A in step 203, and the process jumps to step 206. If the spelling is incorrect in step 202, the buzzer 78 is sounded, for example, three times in step 204, 1 is stored in the accumulator A in step 205, and the process proceeds to step 206. In step 206, the contents of accumulator A are stored in the spell check flag, and the process returns to the main routine. Thus, in the electronic typewriter of the present embodiment, when the misspelled word is keyed in,
A buzzer gives an audible warning.

The search for the mark pointer in step 133 in FIG. 1 is performed in the mark pointer search subroutine shown in FIG. In this mark pointer search subroutine, the display pointer is set to 0 in step 301, the display start address is stored in the work area WORK in step 302, and it is determined in step 303 whether the value of the work area WORK is smaller than the transfer address. If it is smaller, the process jumps to step 305, and if it is not smaller, the display pointer is stored in the mark pointer in step 304, and the process proceeds to step 305.

In step 305, it is determined whether the value of the work area WORK is smaller than the carrier address, and if not smaller, the process returns to the main routine. If small, step 306
The value of the work area WORK + (display pointer + 100H) is stored in the work area WORK again, the display pointer is incremented by 1 in step 307, the process returns to step 303, and the following steps are repeated.

The process of marking the LCD in step 134 of FIG. 1 is performed in the LCD mark subroutine shown in FIG. In this LCD mark subroutine, at step 401 (LCDBUF + (mark pointer))
Then, in step 402, it is determined whether or not the content of the accumulator A is a space, and if it is not a space, the process jumps to step 406. If space, step 403
0 is stored in accumulator A, and the value of accumulator A is set to (LCDBUF + (mark pointer) in step 404.
+ 200H), the mark pointer is counted down by 1 in step 405, the process returns to step 401, and the following steps are repeated. In step 406, the value of the spell check flag is stored in the accumulator A, and in step 407, the value of the accumulator A is set to (LCDBUF
Store it at the address of + (mark pointer) + 200H) and return to the main routine.

The LCD display in step 135 of FIG. 1 is shown in FIG.
This is performed in the LCD display subroutine. In this LCD display subroutine, the display on the display device 4 is cleared in step 501, the LCD display start pointer is searched in step 502, and the error flag is turned off in step 503. Next, in step 504, the contents of the display pointer are displayed, and in step 505 it is determined whether the error flag is on. If the error flag is on, the process jumps to step 510. If the error flag is not on, in step 506 the accumulator A (LCDBUF + (display pointer) + 20
The contents of the address of 0H) are stored, and it is determined in step 507 whether the accumulator A is 0. If it is 0, the process jumps to step 510. If it is not 0, the LCD address is stored in the work area WORK in step 508 and step 5
Turn the error flag on at 09. In step 510, the display pointer is counted down by 1, and in step 511, it is determined whether the display is finished. If not ended, the process returns to step 504 and the following steps are repeated. If the display is completed in step 511, it is determined in step 512 whether the error flag is on. If not, the process returns to the main routine. If it is on, the cursor address is set from the work area WORK in step 513, the blinking of the cursor is started in step 514, and the process returns to the main routine. As described above, in the electronic typewriter of the present embodiment, when the cursor is positioned at the first character of the misspelled word, the cursor is blinking displayed.

On the other hand, when the back key 13 is pressed, the back key subroutine shown in FIG.
At 1, the carrier 5 is backed by one character. With the return movement of the carrier 5, the display on the display device 4 is also backward scrolled by one character. next,
In step 602, the position on the collect buffer 91 is searched from the current carrier position, and in step 603 it is detected whether the most significant bit of the collect buffer 91 is set. If the bit is set, the process returns. If the bit is not set, it is detected in step 604 whether or not the back key 13 is pressed. If the back key 13 has been pressed, the process returns to step 601, and the following steps are repeated. If the back key 13 has not been pressed, the process returns. Therefore, in the electronic typewriter of the present embodiment, if the back key 13 is continuously pressed, the carrier 5 is moved back one character at a time and stopped at the head position of the misspelled word. Therefore, the effort to search for misspelled words is reduced.

In the present embodiment, the key for moving the carrier 5 back is the back key 13, but it goes without saying that other keys may be used.

〔The invention's effect〕

As described above, according to the present invention, when a misspelled word is keyed in, a voice warning is given, so that the typist can immediately notice the misspelled word, and automatically by operating a specific key. Since the carrier will return to the misspelled word, there is an effect that the word for correction can be searched easily and quickly.

Further, in an electronic typewriter equipped with a display device, the cursor blinks when the cursor is located at the first character of the misspelled word, so that the misspelled word can be searched more easily.
