Claims (1)

일단에 힌지 결합되어 스프링으로 탄지되도록 설치한 전자 악기에 사용되는 건반에 있어서, 스프링(2)으로 탄지되는 건반(1)이 하측 중간부에 돌출부(3)를 형성하고 상기 돌출부(3) 중앙에 수직방향으로 소정간격을 맞는 제1감지홀(4)과 제2감지홀(5)을 형성하고 프레임(6)의 상단에 일치된 PCB 기판(7)에는 상기 돌출부(3)와 대항되는 위치에 일측은 발광다이오드(10)를 타측에 포토 트랜지스터(11)를 설치하여서 된 것을 특징으로 하는 전자악기의 건반장치.In a key used for an electronic musical instrument which is hinged at one end and installed to be supported by a spring, a key (1) carried by a spring (2) forms a protrusion (3) at the lower middle and a protrusion (3) at the center of the protrusion (3). The first sensing hole 4 and the second sensing hole 5 are formed in the vertical direction, and the PCB substrate 7 corresponding to the upper end of the frame 6 is formed at a position opposed to the protrusion 3. The keyboard device of the electronic instrument, characterized in that one side is provided with a light emitting diode (10) on the other side of the photo transistor (11). ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
