Claims (3)
- 모래시계 형상의 유리관과;
상기 유리관 상단에 결합되는 전자석과;
상기 유리관 하단 내부에 채워지는 쇳가루와;
상기 전자석에 시간에 따라 순차적으로 자력의 크기를 증가시키는 출력을 입력시키는 제어회로부와;
상기 유리관 하단에 상기 제어회로부의 전자석 출력을 시작시키는 터치 스위치로;
구성되어 시간에 따라 상기 쇳가루가 상승하여 올라가는 것을 특징으로 하는 반중력식 모래시계. - 제1항에 있어서,
상기 반중력식 모래시계는, 상기 제어회로부에 의해 제어 구동되는 스피커가 더 포함되어 구동되어, 상기 쇳가루가 유리관 하단으로 모두 올라가는 시간에 알람을 발생시키는 것을 특징으로 하는 반중력식 모래시계. - 제1항 또는 제2항에 있어서,
상기 반중력식 모래시계는, 타이머 입력 수단을 마련하고, 상기 제어회로부는 상기 타이머 입력 수단으로 입력된 시간에 모래시계의 1회 작동이 완료되도록 상기 전자석의 출력을 조정시키는 것을 특징으로 하는 반중력식 모래시계.
