The present invention classifies the Hangul alphabet, numbers, and symbols on a daisy-type electronic print wheel into groups according to the Hangul combination type, considering the frequency of use of each device, coupling frequency and size, etc. The first embodiment of the present invention relates to a single-row print wheel of an electronic printer in which Hangul alphabet, numbers, and symbols are arranged to improve the quantification of Korean characters and increase the printing speed by sequentially arranging them on the spokes in the order and position of the phoneme arrangement sequence table.

In order to beautify the qualities of the Hangul alphabet, numbers, and symbols in the present invention, as shown in Fig. 1, a, b, c, d, ㅁ, ㅂ. , ', ·-? Looking at the uses classified as!,

1) Consonants with serial numbers 1-19 according to the classification chart of FIG. 1 are consonant groups used in front of the horizontal vowels, of which the serial numbers 2,3,4,5,6,12,13,16,17,18,19 Eleven consonants are consonant groups commonly used in front of vertical vowels, and eleven of 3, 5, 6, 7, 9, 10, 11, 12, 13, 14, and 15 are classified as common. And

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

3) The serial numbers 28-31 according to the classification chart of 1 are classified separately because they are a high frequency of single support consonants, and the other supports are moved to the support group by moving the consonants used in front of the horizontal collection as in 1) above. To use,

4) The double support group up to serial number 32- according to the classification chart of FIG. 1 was classified, and the low support double support ㄽ and ㄿ were deleted here and other consonants were used in combination.

5) The middle vowel group of serial number 42-44 according to the first degree classification table was classified so as to enter only between the initial consonant and the vertical vowel,

6) The vertical collection group of serial numbers 45-52 according to the classification chart of FIG. 1 is used when there is a bearing, and the vowel "H" with a very low frequency is deleted to be shared with the serial number 59.

7) The vertical collection group of serial number 53-61 according to the classification chart of FIG. 1 is to be used when there is no support.

8) The horizontal collection group of serial numbers 62-66 according to the classification chart of FIG.

9) The horizontal collection group of serial number 67-71 according to the classification chart of 1 is to be used when there is no support.

10) Ten of the serial numbers 72-81 according to the first degree classification table are numbers, and fifteen of the serial numbers 82-96 are codes, and the symbols not included in the classification table =,:, ",;, are the above 15 codes. -, ·, ', ", In combination to make it possible to print.

As described above, the present invention, which classifies Korean consonants, numbers, and signs, separates the consonant group that comes before the horizontal vowel and the consonant group that comes before the vertical vowel according to the nourishment. When you look at the combination type of each letter when composing letters by combining the phonemes of each Hangul, as shown in Figure 2,

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: Consonants + Horizontal Bars

There are six types of.

In other words, type 1 can be classified as "Wang", type 2 as "and", type 3 as "angle", type 4 as "A", type 5 as "Song", and type 6 as "High". "Jharo can be displayed beautifully according to the type used in the vertical collection and the horizontal collection and the type used in the single and double bearings.

Thus, in order to increase the printing speed in the first diagram, which is classified as beautiful letters of Korean alphabet, numbers, and codes, the letters are arranged on the surface of the print wheel with high frequency according to the frequency of each phoneme and the combination frequency according to the character composition. There was a need to increase the print speed by shortening the rotation distance of the print wheel.

Therefore, in order to investigate the frequency of use and binding frequency, 557,494 of the 216,615 characters randomly extracted from general documents, newspapers, magazines, etc., were classified into Korean phonemes and frequent surveys (Hangul Mechanization Institute 1970.8) and Korean frequent surveys (Hangul mechanization). The Korean alphabet type is collected by VVS (vertical vowel), VVL (vertical vowel), VHM (middle vowel), VHS (horizontal vowel), VHL (horizontal vowel) and consonants are used on the middle vowel. Consonants (C ₁ ), consonants used before vertical vowels (C ₂ ), consonants used before vertical vowels (C ₃ ), consonants used on horizontal vowels or horizontal long vowels (C ₄ ), and consonants used as support ( C ₅ ), and the frequency of Hangul frequency survey was investigated.

For example, the letter # of the classification number 22, the No. 1 frequency ranking, is used for C _{2 and} C ₃ in the classification table, and 30,324 of the total 557,494 elements were 5.439%, and 1,000 were used. 54,39 characters per element were used.

In addition, the number 14, the number 14, the frequency rank 40th, is used in the classification classification table for C _1, C ₄ and C ₅ , with 3,493 elements out of a total of 557,494 elements surveyed, with a usage rate of 0.6265% and 1,000 characters. 6,265 elemental sugars were used to investigate the frequency of each elemental body as in the third plot.

By arranging up to high frequency phoneme group with high use frequency and binding frequency by frequency, printing speed can be increased, but it is a problem in forming by exceeding the minimum distance between letter and type, and rotation of print wheel is unbalanced. At the same time, there was a risk of typos occurring outside the range of each character.

Therefore, the arrangement of the present invention is arranged according to the frequency sequence and the combination frequency according to the letter configuration as described above (for example, which VVS comes to the consonant C _{2 a} lot), but each letter plate (character when the large width of the shape of the print wheel are adjacent to each other. In the range that maximizes the printing speed by frequency order in consideration of the molding problem by exceeding the minimum interval between fonts, the area of each character is measured so that it cannot be mistaken due to the rotational speed error due to the wheel imbalance. In consideration of the operation balance of the daisy type print wheel, 96 characters were continuously arranged on the daisy wheel as shown in FIG.

The arrangement sequence of the 96-characters of FIG. 6 is completely shown as the top view of the print wheel of FIG.

The present invention as described above is arranged in accordance with the combination frequency according to the frequency and character composition of the phoneme in consideration of the use frequency and size of the phoneme in order to enhance the speed of printing and to enhance the speed of printing the Hangul alphabet, numbers, letters, etc. In order to balance the font width according to the font area and the wheel operation, it is continuously arranged in 96 spokes of the daisy wheel in the order of the arrangement of FIG. When explained by the electronic printer system as shown in FIG. 8, data from a key board is collected from C, PU, and Korean characters to form a logic ( Logic) and send it to the amplification circuit to drive print wheel, carriage, platen, etc. It is wide and drives the print wheel, carriage and platen, and the driving positions of the dual print wheel and the carriage are fed back to the servo circuit through the converter, and when an error occurs, a correction signal is output through the amplification circuit. And it is sent to the carriage drive servo motor (servo motor) to be positioned correctly.

By using the printer system as described above, the letters are selected by driving the print wheel, the carriage is controlled to determine the left and right positions of the phoneme, and the platen is controlled to determine the upper and lower positions of the phoneme.

As described above, the present invention classifies the Hangul alphabet, numbers, and symbols into groups according to the Hangul combination type, considers the frequency of use, coupling frequency, and dimensions, and then measures the area of each character to balance the print wheel and rotate the wheel. The error is prevented and it is resolved as in the fifth degree so that the printing speed is fast and the nourishment of the letters is also good.
