Abstract
본 키보드 홀딩장치는 컴퓨터시스템 이용중에 키보드를 통해 데이타를 입력하는 상황이 아닐 경우에는 키보드를 홀딩하기 위한 것이다. 이를 위하여 본 장치는 키보드에 장착되어 키보드를 홀드시키기 위한 홀드키; 홀드키가 제어되면, 소정의 펄스폭을 갖는 원펄스를 발생하기 위한 원펄스발생기; 본체에서 발생되는 클럭신호에 동기를 맞추어 원펄스를 출력하는 D플립플롭; D플립플롭의 출력단에 인에이블단자가 접속되어 상기 출력단을 통해 출력되는 신호에 의하여 인에이블상태가 제어되는 키보드 프로세서; D플립플롭의 반전출력단을 통해 출력되는 신호의 논리상태에 따라 키보다가 홀딩상태인지 아닌지를 판단하는 마이컴을 포함하도록 구성된다.The keyboard holding device is for holding the keyboard when the data is not inputted through the keyboard while using the computer system. To this end, the device comprises a hold key mounted to the keyboard to hold the keyboard; A one pulse generator for generating a one pulse having a predetermined pulse width when the hold key is controlled; A D flip-flop that outputs one pulse in synchronization with a clock signal generated by the main body; A keyboard processor having an enable terminal connected to an output terminal of the D flip-flop and having an enabled state controlled by a signal outputted through the output terminal; And a microcomputer that determines whether the key is in the holding state according to the logic state of the signal output through the inverted output terminal of the D flip-flop.
