Korean typo detection control method

1 is a schematic diagram of a control system of the present invention.

2 is a Hangul combination type table.

3 is a main control part and a control panel of the present invention.

4 is a mechanical diagram used in the present invention.

The present invention relates to a Hangul typographic typewriter, and to a Korean typo detection control method that detects and displays a typo when a typo occurs, and prevents typos of typos. If the correct syllable is memorized, the next syllable is memorized and printed so that the correct typing can be done. The present invention relates to a Hangul typos detection control method for driving a user to recognize a typo and preventing typos from being printed.

Conventional Hangul electronic typewriter is a typo input that is inconsistent with the Hangul combination type or grammar, it does not detect this by printing it as it does not prevent the occurrence of typos by printing as it is, there was always the inconvenience to erase or re-type at the time of typo, the present invention is such a conventional In order to eliminate the flaw of typos caused by Korean electronic typewriters, the Korean type is reduced to a 2 type keyboard type by using an electronic typewriter using a microprocessor. Incorrect input error and 6 combinations of Hangul combination type that do not fit in, but detected a typographical error such as double consonant that does not exist in Hangul, the warning light is turned on and a warning sound sounds for a certain time. .

According to the present invention, when a keyboard corresponding to a letter is pressed in the keyboard unit 1, the signal is not immediately printed, and the signal is interrupted to the seeds, blood, and oil (CPU) 11 of the main controller 2. After detecting the input, it reads the key board information codes sequentially according to the instructions of the main control program stored in the main control memory (ROM / EPROM). And a function, and in the case of a code of English, numeral, and sign, immediately transmits a control command to the argument control unit 4 through the transfer unit 3, and in the case of Korean code, the writing is done. Waiting to store temporarily in memory until the clause is completed, and when the next syllable is completed in the next sequential input, the control program classifies it into Hangul combinatorial 6 classification formula (figure 2). And the print command of the Hangul alphabet and horizontal, vertical, and shift commands according to this are sequentially sent to the print control unit 4 through the transfer unit 3, and the print wheel through the servo control unit 5 It is comprised so that printing by the drive part 6, the carriage drive part 7, and the conversion part 8 may be carried out.

And Hangul combination syllable of memory for Hangul syllable collection input. The transfer unit 3, the print control unit 4, the servo control unit 5, the print wheel drive unit 6, and the carriage drive unit 7 are used as control signals of the main control unit 2 at the time of inputting a motor and a continuous typo that deviates from grammar. The Hangul typo configured to recognize the memory input by tying the warning light (D ₁ ), the driving unit (Q ₁ , Q ₂ ), and the buzzer (B) of the control panel unit 10 so as not to be controlled and printed. It is a detection control method.

Therefore, in the present invention, unlike the conventional typewriter, which is pressed at the same time as pressing the keyboard, the vowels of Hangul are stored in the memory unit until one syllable is completed and the next syllable is inputted. VVS (vertical vowels), VVL (vertical vowels) ), VHM (middle vowel), VHS (horizontal vowel), VHL (horizontal vowel). Consonants are consonants used on the middle vowels, consonants used before the vertical vowels, consonants used before the vertical vowels, horizontal vowels After classifying the consonants used on the horizontal long vowels and the consonants used as the backing, the Korean consonant type is classified into six classifications so that the same consonants and the same vowels can be printed in different shapes according to the position of the factories.

For example, if a single phoneme is input from the keyboard (keyboard part) by the microprocessor, the corresponding phoneme is selected according to the Hangul argument type (second diagram) according to the Hangul combination type. A) Even if the letter is a typo while the phoneme of Korean syllables is input and memorized in a different form depending on the type used in the vertical and horizontal vowels and the type used in the single and double supports, It detects this and drives the warning light (D ₁ ) and the warning sound buzzer (B).

Therefore, looking at the type of typo detected by the present invention,

First, if you enter the vowels without the consonant

Example: ㅓ, ㅕ

2) If you enter the horizontal bar twice

Example: ㄱ + ㅗ + ㅛ (consonant + horizontal vowel + horizontal vowel)

3) If you enter the vowel twice

Example: ㅂ + ㅏ + ㅏ (consonant + vertical vowel + vertical vowel)

4) When the order of horizontal and vertical vowels is changed

Example: ㅇ + ㅏ + ㅗ (consonant + vertical vowel + horizontal vowel)

5) If you enter the first consonant twice (a, b, c, d, k, k, k, k, k, k, k, k, k, h, k, k, k, k) For input)

Example: ㄴ + ㄷ + ㄹ + ㄹ

Second, if it corresponds to Hangul combination type 1 or 3 in FIG. 3 but the horizontal middle vowel is ㅛ, ㅠ

Example: ㅇ + ㅛ + ㅏ

Third, it corresponds to Hangul combination type 1 or 3 in FIG. 3, but the vertical vowel is ㅑ + ㅕ + ㅒ + ㅖ

Example: ㅇ + ㅗ + ㅑ

Fourth, if it corresponds to Hangul combination type 1, 3 or 5 of FIG.

Example: 복, ㅆ, ㄳ, ㄻ, ㄵ, ㄶ, ㄺ, ㄿ, ㄽ, ㅀ, ㅄ, 복 other than the brace.

In this way, when a typo occurs that is inconsistent with the Hangul combination type and Hangul grammar, the seed, blood and milk of the main control unit 2 reads the keyboard input by the main control program and the program of the main control unit 2 in the memory. After detecting this, the control panel unit 10 is operated through the output unit of the main control unit 2 so as not to be printed as the print command state signal through the transfer unit 3.

That is, the main control unit 2, the storage unit 9 and the printing manufacturing unit 4 of the present invention are digital units which control operations to be performed, respectively, a microprocessor, a memory I, C, RAM, ROM, TTL, I, C By configuring the hardware (Hard Ware), the servo controller 5, the print wheel drive unit 6, the carriage sphere 7, and the converting unit 8 are configured to perform the operation indicated by the digital unit as an analog unit. As shown in FIG. 3, the unit 2 includes the CPU 11 which performs all functions of the main control unit and the output of a RAM and a control panel unit capable of storing data. And a RAM 12 serving as an input / output port capable of processing switch input and keyboard data input, and a driver 13 of a data bus driver that sends and receives data to and from the ROM 16 and storage and printing control unit. 13 ') and the lower address 8Bit for time division multiple communication with data. The control unit and the C / P of the driver bus 14 of the address bus driver and the CPU 11 which latch only the address and send it to the ROM, the print control unit, and the storage unit. Control signal interpretation (15) for control signals that make the necessary control signals using the oil state signals, and ROM or EPROM (16) containing all control programs for moving the CPU, CPU, etc. They are supposed to work together.

In addition, the print control unit 4 stores the typewriter operation state and transmits the state to the main control unit 2 as necessary to prevent a malfunction in the printing process, and knows whether there is an operation to be performed by the cock. The function flip-flop is continuously investigated, which is performed by an instruction sent from the microprocessor in the argument controller 4.

At this time, if there is an operation to be performed, the corresponding flip-flop is set (set switching) to control and adjust the driving devices 6, 7, and 8 to perform the actual operation according to the data value stored in the printing control unit 3. It is supposed to.

In this way, the CPU 11 of the main control unit 2 is written when there is data input from the keyboard unit 1, and the control program in the ROM 16 of FIG. The keyboard character code is read into the RAM 12 of FIG. 3 until the data of the keyboard portion is read through the RAM (2) of the input / output foot by the instruction, and the Hangul syllable is formed by the Hangul syllable identification function of the control program. Save it.

After the Hangul one syllable is composed by sequential keyboard input (when entering the first consonant of the next syllable or the vowel input), the control program classifies one of the Hangul combination types of FIG. 3 into FIG. 3 according to its output type. When the print command of the character is sent to the print control unit through the address and data bus, the print control unit 4 sends to the servo control unit 5, and this signal is amplified in each drive unit to drive the print wheel, the carriage platen, and the like. When a typo (adjustment signal) is generated by printing, the driving positions of the plant wheel and the carriage are fed back to the circuit of the servo control section 5 through a transnaducer 8 to be corrected through an amplification circuit. The signal is sent to each servo motor through the print wheel and carriage drive 6 and 7 to determine the correct print position.

Therefore, normally, the control panel unit (FIG. 2) sends the high potential data DATA from the CPU 11 of the main control unit 2 to the memory and the unidirectional force RAM & I / O. 10) receives the high-potential state signal from the output terminal (PB ₂ ), the transistor (Q ₁ ) is conducted and flows to the emitter of the idle transistor (Q ₁ ), so that the bias power is not applied to the base of the transistor (Q2). Therefore, when the buzzer (B) does not operate and a typo occurs, the potential is low for a predetermined time from the CPU 11 to the output terminal PB ₂ connected to the memory and the input / output (RAM & I / O) terminals. will send a status signal ringing transistor (Q ₁₎ are down is the base bias supply (+ 5V) of the transistor (Q ₂₎ is on and the transistor (Q ₂₎ is a buzzer for a predetermined time (B) is driven as conducting.

In addition, the warning light D ₁ also sends a high-potential status signal from the C.P.11 to the output PB ₁ of the main control unit 2, so that the warning light D ₁ does not light up. The warning lamp D ₁ is turned on by sending a low-potential state signal to the main control unit 2 and the output PB ₁ .

At this time, the transmission unit 3 does not transmit the print command signal, the print wheel drive motor or the carriage drive motor does not operate, and thus does not print at all, and recognizes the generation of a typo.

In this typo input state, if you do not clear it, and keep pressing the keyboard to input, the warning light and the buzzer buzzer continue to operate and the letters cannot be printed at the same time. Typos are made in memory, so you can type them again and continue printing the correct characters.

As described above, in the present invention, when the Hangul combined writing memory is matched with the Hangul combined form or grammar, the next syllable memory is memorized, and the Hangul combined form including Hangul one syllable gathering input memory, or the grammar is not corrected when the grammar is inconsistent. At the same time, a warning light and an alarm sound for a certain period of time, allowing the user to recognize a typo, thereby eliminating the trouble and trouble of typing or retyping a typo. It will be saved.
