In the present invention, a printer using a microprocessor (PRINTER), the Hangul alphabet, numbers, codes, etc. are classified into groups so that the same elements can be arranged in a number of digits so as to be printed as selected qualities according to a coupling relationship of letter combination types. It relates to a character classification method of an electronic printer.

In the case of Hangul, it is necessary to use the keyboard according to each printing status in order to express the printing state of the printer beautifully. Also, the printing speed should be taken into account in order to express the fast and beautiful nourishment.

The present invention adds the typeface of the wheel in consideration of the specificity of the Hangul, to be a factor in different traits according to the input of the keyboard, while the harmony of the state of each factor is beautifully expressed, it is possible to quickly at the speed of printing 557,494 of the total 216,615 characters randomly extracted from documents, newspapers, magazines, etc. were classified by Hangul alphabet classification and frequent survey (Hangul Mechanization Institute 1970.3.) And Hangul frequent survey (Hangul Mechanization Institute 1975.8). By examining the frequency of Hangul, the vowels are VVS (vertical vowels) and VVL (vertical vowels). It is divided into VHM (middle vowel), VHS (horizontal vowel), VHL (horizontal vowel), and consonants are used before consonants (C ₁ ) and vertical vowels before vertical vowels (C ₂ ). Consonants (C ₃ ), consonants (C ₄ ) used on horizontal vowels or horizontal long vowels, and consonants (C ₅ ) used as backings. In consideration of the printing speed, the Hangul's shape is considered to be beautifully classified. If only one element is input from the keyboard (keyboard part) by the microprocessor, the Hangul factor type according to the Hangul combination type ( By selecting the corresponding phonemes so that they can be selected according to the 1 degree), the same consonant, even if the same consonant, is used according to the type used in the vertical and double bearings, in front of the vertical and horizontal collections. Each becomes an argument type of Hangul classified to a different form factor.

If it described in detail by the embodiment of the accompanying drawings as follows.

In the present invention, as shown in Table 1, the Hangul alphabet, numbers, signs, etc. a, b, c, d, d, k ... … 96 types are classified into ',', ㆍ,?,!

One). The consonants of serial numbers 1-19 according to the classification table are consonants used in front of the horizontal vowels, and 11 consonants of double serial numbers 2, 3, 4, 5, 6, 12, 13, 16, 17, 18, and 19 Is a consonant group commonly used in front of vertical vowels, and 11 of 3, 5, 6, 7, 9, 10, 11, 12, 13, 14, and 15 are classified as common.

2). Consonants up to serial numbers 20-27 according to the classification table are consonant groups used only in front of vertical vowels, and other consonants are 1) above. As in the paragraph, it was shared with the consonants used in front of the horizontal vowels,

3). Serial number 28-31 according to the classification table 1 because it is a high frequency single support consonant group was classified separately, and other support is 1) above. As in the paragraph, the consonants used in front of the horizontal vowels were moved and used as a support group

4). The serial numbers 32-41 according to the classification table were classified into double support groups, and the low frequency double support ㄽ, ㄿ was deleted here and used in combination with consonants by other methods.

5). The middle vowel group of serial number 42-44 according to the classification table was classified only between the initial consonant and the vertical vowel.

6). The vertical collection group of serial number 45-52 according to the classification table is used when there is a support, and the collection of extremely low vowel ＂ㅒ＂ is deleted to be shared with serial number 59.

7). The vertical collection group of serial number 53-61 by the classification table is to be used when there is no support.

8. The horizontal collection group of serial number 62-66 according to the classification table 1 is to be used when there is a support.

9). The horizontal collection group of serial number 67-71 according to the classification table is to be used without support.

10). In Table 1, 10 of the serial numbers 72-81 are numbers, and 15 of the serial numbers 82-96 are codes, and the code without the classification table =,:, ',; is among the above 15 codes-, ?, ',' ″ Can be combined for printing.

As such, according to the present invention, the Korean alphabet, numbers, codes, and the like are classified into consonant groups that precede the horizontal vowels and consonant groups that precede the vertical vowels and the consonants that are judged to be necessary according to nourishment, as shown in FIG.

Type 1: Consonant + Middle Bar + Vertical Bar + Bar

Type 2: Consonants + middle vowels + vertical vowels

Type 3: Consonants + vertical vowels + support

Type 4: Consonant + Vertical Bar

Type 5: consonants + horizontal vowels + support

Type 6: It is classified into consonant + horizontal vowels and applied to the system of electronic printer using the microprocessor of FIG.

That is, the character classification method of the present invention will be described as an embodiment to which a microprocessor is applied.

The main control unit 2, the storage unit 8, and the print control unit 3 are digital boards for controlling the operations to be performed, and each of the necessary microprocessors, memory, I, C RAM, ROM, TTLIC, hardware ( Hardware, and the servo controller 4, the print wheel driver 5, the carriage driver 6, and the converter 7 are configured to perform the operation indicated by the digital part as an analog board.

As shown in FIG. 4, the main controller 2 is composed of a CPU, a CPU 9 which performs all functions of the main controller, a RAM capable of storing data, and Input / output port inspection (10) capable of processing the output of the control phenyl part, switch input, and keyboard data input (10), data bus driver (11) for sending and receiving data to and from the ROM (ROM), storage unit, and printing control unit; The address bus driver 12, which separates the lower address 8 bit for time division multiple communication, latches only the address, and sends it to the ROM, the print control unit, and the storage unit, and C, P and U (CPU). (9) Using the control signal and the seed, blood and significant state signals, the necessary control signal is a ROM (or ROM) or a pyrom containing the control signal decoder (1) to make and all the control programs for moving the seed, blood and oil ( EPROM) 14.

In addition, the printing control unit 3 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. The function flip-flop is continuously scanned, which is performed by an instruction sent by the microprocessor in the argument control unit 3.

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 device (5) (7) (8) to perform the actual operation according to the data value stored in the printing control unit (3). Control).

That is, the print control unit 3 calculates and controls the print position of the entire state and the print position to be printed when the print command and the data of the print command are received from the main control unit. Send the velocity velocity (Initial Velocity) to the servo control board (Return Servo Board), convert it to an analog value, and send it to the print wheel driver (5). The print wheel driver (5) drives the print wheel motor. Instead of continuously turning at a constant speed, the converter 7 receives a feedback signal from the motor and sends it to the print control unit 3 through the servo control unit so as to decelerate as it approaches the desired print wheel position. By sending the speed corresponding to the position to move to the servo controller, the print wheel motor is decelerated. It is to end the print wheel such that a factor to stop, and wherein the driving hammer (Hammer) at the desired print position.

Even in the moving operation (carriage or platen), the printing control unit 3 receives a command from the main control part of the type of the type to be printed in the left, middle, and right directions along the center point of the printing type. It calculates and judges the position (left, middle, right) and the position of the type to be printed, and sends it to the servo control unit according to the fastest printing speed for each printing type to convert it into an analog value.

The carriage is operated in accordance with a command received from the carriage driver 6 so that the carriage drive motor is driven in fine steps. The converter 7 feeds back a feedback signal from the motor to the servo controller ( Servo Board) and the position of the left, middle, and right is determined correctly according to the signal detected by the printing controller.

At this time, by repeating the control and adjustment according to the mutual circulation with the platen, the center point of the type of the correct type is selected. In the operation of the platen (Paper Feed), the feedback motor is stepped by the step motor. It is controlled directly by the print controller.

In this way, the seed, blood, and oil 9 of the main control unit 2 are written when there is data input from the keyboard unit 1, and input / output by the instruction of the control program in the ROM 14 of FIG. The keyboard character code is read through the port 10 and temporarily stored in the RAM 10 of FIG. 4 until the Hangul syllable is formed by the Hangul syllable identification function of the control program.

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. 1 into the one shown in FIG. When the printing command of the element is sent to the printing control unit via the address and data bus, the printing control unit 3 sends the servo control unit 4, and this signal is amplified by each driving unit to drive the print wheel, the carriage, the platen, and the like. When an error (adjustment signal) is generated by printing, the driving position of the print wheel and the carriage are fed back to the circuit of the servo control unit 4 through a transformer 7 to be corrected through an amplification circuit. Status signals are sent to the respective servo motors via the print wheels and carriage drives 5 and 6 to determine the correct print position.

That is, according to the classification method of the present invention, the microprocessor can store the type of the Hangul syllables and store the position and velocity for each factor type according to the Hangul combination at the proper position along the center point of each syllable (phoneme). The microprocessor composed of a servo motor is used to classify Hangul parameters by determining, commanding, driving, returning, and adjusting each other. It can be.

Examples of such types are as follows.

, ′, ', ㆍ,(일련번호 30, 7, 13, 87, 92, 93, 94)로 조합하여 인자할 수 있으며 역시 수평모음과 수직모음앞에 쓰이는 자음군을 따로 구분시키고, 수직모음 앞에 쓰이는 자음군을 받침의 유무에 따라 상, 하로 위치를 변경시키어 인자함으로서 한글의 자양을 아름답고 인자속도가 신속하게 개선한 효과가 있는 것이다.In other words, the first type can be classified into two types, the first type, the second type, the third type, and the fourth type, the fifth type, the sixth type, and the sixth type. For example, in the case of the letter vowels in the keyboard section of only one vowel, the letter, blood, It reads as U (9) and temporarily stores it in RAM (10) until the Hangul one syllable is composed, and after completing the syllable, the composition syllable or vowel of the next syllable Recognize and classify as one of the Hangul combination types, and depending on the type, the same consonant of the same input, even if it is a different type according to the type used in the vertical support and the horizontal support, and the type used in the vertical and horizontal support The data bus driver 11 must be supplied with different signals (in this case, C ₁ of the initial consonant and C ₅ of the support convex). By sending it to the argument control unit, the Korean alphabet is classified so that it can be displayed beautifully. The other consonants and vowels below will have the same effect as the ＂ㄱ＂ consonants according to their positions, and are arranged in the keyboard as a pair of vowels. According to the combination type and factor type and binding frequency of one element, the different types of elemental elements (4-5) are allowed to be printed to simplify the keyboard, improve the nourishment, and increase the printing speed. And, the present invention is a special letter and code

And =,:,-, ″ are defined by the 96 classification table in Table 1.

It can be printed by combining with ',', ', ㆍ, (serial number 30, 7, 13, 87, 92, 93, 94). Also, separate consonants used in front of horizontal and vertical vowels. By changing the position up and down according to the presence or absence of the bearing, the nourishment of Hangeul is beautiful and the printing speed is effective.
