Abstract

현재 사용하고 있는 키보드 한글 및 영문전환시 영문모드인지 한글모드인지를 모니터의 화면을 보고 확인하지 않으면 한글입력시 영문이 입력되고 영문입력시 한글이 입력되는 경우가 발생하게 되어 한글/영문키를 다시 전환시켜야 하는 사용자의 번거로움과 불편함이 뒤따랐던 것이다.If the currently used keyboard is in Hangul or English, if you check the English mode or the Hangul mode, you may see English characters when you input Hangul and Hangul when you input English. This was followed by the hassle and inconvenience of users who had to switch.

이를 해결하고자 본 발명은 키보드의 뒷면에 서로 다른 색깔을 가진 두 개의 영문/한글 LED를 장착하여 한글전환시 한글부분의 LED가 점등되게 하고, 영문전환시 영문부분의 LED가 점등되게 하여 키입력시에 발생하는 한글/영문의 오타를 사전에 방지시킬 수 있게 하고, 한글/영문의 오타로 인하여 한글/영문키를 다시 전환시켜주는 번거로움과 불편함을 해소시키도록 하는데 있다.In order to solve this problem, the present invention is characterized in that two English / Korean LEDs having different colors are mounted on the back of the keyboard, so that the LEDs of the Korean part are turned on when the Korean language is converted, It is possible to prevent the occurrence of a han- dle / English mistake that occurs in the Korean language and English, and to eliminate the troublesome and inconvenient to switch the Korean / English key again due to the misspelling of Korean / English.
