BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for automatic underlining in Korean vertical writing of a daisy wheel typewriter, and more particularly to a method for classifying carriage driving according to a unit character string standard. Typically, the unit character string specifications are 3Line Per Inch (abbreviated as LPI) with three strings per inch long, 4LPI with four strings per inch, 6LPI with six strings, and eight Separated by 8 LPI with strings, the vertical mark [1] is 1/6 inch long.

Conventionally, in the method of typing Hangul in vertical writing using a daisy wheel, there is a problem in using a typewriter because the automatic underlining cannot be displayed, especially since there is no method for printing the underlining.

The present invention has been made in an effort to provide an automatic underlining method for printing underlining in Korean vertical writing of a daisy wheel typewriter in order to solve such a conventional problem. The explanation is as follows.

1 and 3, the configuration of the apparatus related to the method of the present invention includes a central processing unit (1), a Hangul combination apparatus (2), a Hangul type separator (3), and a unit string (3, 4 LPI). And 6,8 LPI) flag portion (4,5), printing direction flag portion (6), input data storage portion (7), unit character string switch portion (8), keyboard (9), phoneme memory element for each Korean type (10a) -10d) into the Hangul alphabet storage unit 10, the print wheel driver 11, the platen driver 12, the Hangul printing completion flag 13, the carriage driver 14 and the auto underline flag 15 Consists of.

According to the present invention made under such a background, a first process of distinguishing 3,4 LPI or 6,8 LPI is applied by checking the unit character string flag 4 when inputting Korean characters; In the case of 6,8 LPI, a second process of resetting the 3,4 LPI flag part 4 and setting the 6,8 LPI flag part 5 to check whether the printing direction flag part 6 is set; Depending on whether the printing direction flag portion 6 is set or not, the printing direction flag portion 6 is reset or set. If the printing direction flag portion 6 is 3,4 LPI, the 6,8 LPI flag portion 5 is reset and the 3,4 LPI is reset. A third step of setting the flag portion 4 to reset the printing direction flag portion 6; A fourth step of checking whether the Hangul argument completion flag unit 13 is completed; If it is completed, check whether it is underlined, and if it is underlined, drive the platen drive unit 12 to feed the paper upwards, print the vertical mark [1] with the print wheel drive unit 11, and then platen again. After driving the drive unit 12 to move the paper upwards, the print wheel drive unit 11 again prints a vertical mark [1] to check whether the 3,4LPI flag unit 4 is in the set state. A fifth step of immediately checking whether or not the 3,4LPI flag portion 4 is in a set state; In the fifth process, if the 3,4LPI flag 4 is reset, the carriage drive 14 moves to the neutral position. In the case of the set, the carriage drive 14 moves to the initial position. ; If the Hangul printing is not completed in the fourth process, the Hangul printing completion flag portion 13 is set, and the printing data is read from the Hangul combination device 2 and the Hangul alphabet storage unit 10, and the printer wheel driving unit 11 and After outputting to the platen driving unit 12 and printing, it is checked whether one Hangul is completely output from the Hangul phoneme memory unit 10, and if it is completely output, the Hangul Factor Completion Flag unit 13 is reset to return to the fourth process. If one Hangul is not completely output, it is composed of a seventh process that considers that the Hangul factor is not completed again. In the first process, the reason for dividing the 3,4LPI flag part and the 6,8LPI flag part is the vertical mark. If the length of [1] is 6,8LPI flag, you can print only 1 time, but in case of 3,4LPI, when printing only 1, the underlining becomes far as shown on the left side of the figure below. To.

When explaining the operation and effect of the method of the present invention in detail, it is possible to check whether the current LPI switch 8 is pressed when the Hangul is completely combinable and start typing, or in the case of the memory typewriter, when typing the contents of the memory. In this case, the corresponding LPI flag portions 4 and 5 are controlled, and the printing direction flag portion 6 is controlled according to the LPI flag portions 4 and 5.

If it is not completed by checking the Hangul argument completion flag unit 13, the Hangul argument completion flag is set to indicate that it has not been completed, and the printout data and output from the Hangul combination device 2 and the Hangul alphabet storage unit 10 are displayed. The number of printed factors is printed and output to the print wheel driver 11, the platen driver 12, and the carriage driver 14, and the Hangul alphabet storage unit 10 is reduced again so that the Hangul alphabet storage unit 10 is zero. If it is not 0, perform the following process to print again, and if the printing is completed, reset the Hangul printing completion flag unit 13 to indicate completion, and set the automatic underlining flag unit 15 to print the underlining. In the case of automatic underlining, the platen drive unit 12 and the print wheel drive unit 11 are driven to print the vertical mark [1], transfer the platen, and then inspect the LPI flag units (4, 5). Depending on the flag, the carriage may Moving to or in the "neutral" position to continue the printing by the same process again for the next character as above.

In this case, the position of 'choseong' indicates the positions of the right and left sides of the position for printing letters when printing Hangul.

As described above, according to the method of the present invention, when the automatic underlining is performed in the vertical writing of the Hangul, the printing order is increased according to the bidirectional or each LPI, and thus the printing speed is increased and the carriage driving motor is not overwhelmed. It can provide a reduction in power consumption.
