The present invention has a printing system of Hangul characters while improving the quality of Hangul characters pattern by improving the quality of the Hangul characters pattern by automatically reducing the basic size when there is Jongsung and making the average character balance with the addition of the bellows. The present invention relates to a dot matrix printing device for Korean characters, which can greatly simplify the logic structure of a computer and simplify its processing.

The computer-controlled Hangul character terminal entails the design logic of the printing mechanism or software processing in the light of the specificity of the combinatorial logic of Hangul characters. In addition, in order to combine the modulation of dots constituting the image in a form corresponding to the input key of the Hangul character even in the state of being processed by the image terminal, the software or hardware design of the Hangul character must be applied to the logical characteristics of the computer.

In the information processing system of Korean characters known to date, Korean characters are treated as terminals by consonants, vowels, and consonants of the Korean alphabet. Most of the devices were designed by giving an address, and the combination type was set to dozens of types and the image or printing method was induced by the CPU or a separate word processor logic structure.

This method of processing is usually a gathering method corresponding to key input, which is complicated to design Korean characters into a pretty good form of beautiful letters, and the software is also difficult, so that the price of goods is relatively high. Done.

Therefore, most producers reduce the one-to-one correspondence of Hangul characters by other means even if they are less multi-faceted. One standardized "" only method, etc.) was to simplify the argument mechanism and logic.

However, in this case, since the Korean characters are not balanced, the Korean characters are coarse and are inconvenient to read.

As an example, Table 1 shows an example of the Hangul character factor composition developed in the near field.

TABLE 1

○ When the "name" of the table is the basic factor, the "dragon" of the △ table, which is a child in the form consisting of vowels in the middle of the hole, is not balanced with its size and does not have an overall harmony or balance with one letter or sentence of Hangul characters. have.

Therefore, the printed form is unnatural and uncomfortable to read.

The present invention has been made to improve these disadvantages of the prior art, which is intended to give the following technical effects.

That is, the present invention sets the first basic type, which is a combination of only initial and neutral, and the second basic type added with a finality to the first basic type, and the second basic type is not the first basic type. As a means of modulating one basic type into a changed form (e.g., a first basic type of 19 characters x 21 neutral characters = 399 characters for a first age) , Cats, dogs, dogs, gangs, dogs, horses, bran, school, gyu, her, crab, guo, ear, gang, tree, family, etc. .) To improve the quality of Hangul factors and to achieve the low cost dissemination of these items by simplifying the constructional design.

This will be described in detail below.

1 is a system diagram of the present invention.

The character storage device (1), which applies the character designation code (P) input from the CPU or the character control logic device, has the first basic type (19 characters for initial consonants × 21 characters for neutral = 399 types), which is a combination type of initial and neutral only. ) (Or the first variant base type with the first base type reduced by about two-thirds by a dot size row size) and m × n (in response to the application of the letter designation code P). Q) (or m x about (2/3) n (Q ')) serves to generate a dot matrix output having dot size.

The output data Q and Q 'are applied to the pattern reduction and terminal addition circuit 2 and the matrix selection gate 3, which are controlled by control signals from the character generation controller 5, respectively.

The output system of the character storage device 1 varies according to whether the promised character designation code P is the first basic type (or the first modified basic type) or the second basic type, and the character designation code P Is the first basic type, passes through the matrix select gate 3 and is applied to the printhead 4, and again the second basic type passes through the pattern reduction and terminal addition circuit 2 and the matrix select gate 3 Have a configuration to pass through.

The pattern reduction and terminal addition circuit 2 is configured as shown in FIG. 2, and converts the row size of the output data Q of the character storage device 1 into m × about (2/3) n dot matrix. A final addition is added to the output of the size conversion circuit 21 (in this case, when the output data is Q '), the buffer memory 22 serving as a temporary storage device, and the output of the row size conversion circuit 21. Circuit 23 and matrix control circuit 24 for generating control logic thereof.

The matrix selection gate 3 has a configuration in which one of the two dot matrix character data Q and R is selected and applied to the print head 4 according to the matrix selection signal from the character generation controller 5. .

As an example, when the matrix size is 16 × 16 dot size, the effect of the present invention having this configuration will be described.

When the character designation code P is applied to the character storage device 1 from the CPU in response to the keyboard pressing, the character data Q having a predetermined size outputs 16 × 16 dot matrix information.

At this time, when the character designation code P is of the first type, it is directly applied to the printing head 4 via the matrix selection gate 5 so that the printing head 4 dot prints the basic pattern as shown in FIG. .

Since the basic pattern recognizes a pattern in which the combination type of each consonant and the neutral vowel in the character storage device 1 is formed in an ideal form, the type to be printed by the printing head 4 is preferably printed as a uniform Hangul type. . When the character designation code P is of the second basic type, the character data Q of 16x16 dots is converted into a 16x10 dot matrix through the row size conversion circuit 21 as shown in FIG. (In the case of character data Q 'having a 16 × 10 dot configuration, it is directly passed without passing through the row size conversion circuit 21.) At this time, the position of deleting dots is shown in FIG. X ₁ ), (X ₄ ), (X ₇ ). As indicated by (X ₁₆ ), the original pattern is reduced in shape by 2/3.

Thereafter, in the bottom margin of the character of about 16x6, the searched dot matrix is added as shown in FIG. 5 by adding a logic modulation of the final addition circuit 24.

In this case, the final additional circuit 24 stores and stores the 27-character final character pattern of the most ideal form in the form of 16 × 6 dots.

The printing method of the present invention can also be widely used for electrostatic recording, thermal recording, CRT printer, and the like.

As described above, the present invention greatly simplifies control logic and memory logic for printing Korean characters.

Inversely, despite the minimal character port, it has an elevated effect that can create its own beauty to achieve proper balance of Hangul characters in a timely manner.

Therefore, the production of such an article is simplified and has an economical advantage that can be made at a considerably low price, and it has a beneficial feature that can make a beautiful Korean font and ensure good quality.
