본 고안은 건반악기에 있어서 푸쉬버튼식 건반의 탄력 장치를 간편화한 전자악기의 건반장치에 관한 것이다.종래의 건반장치에 있어서는 제2도의 (a)(b)에서 도시한 바와같이 (a)형태의 정우, 걸림턱외에 터치를위한 돌출터지부(111)와 접촉고무(112) 및 절연체(113)가 첨가될뿐 아니라 평판스프링(114)을 지지하기 위한 힌지부(115)와 지지대(116)가 더 필요하게 된다.(b)형태의 경우에는 브라켓(117)에 접촉고무(118)를 고정설치 시키기 위한 홀(119)가공이 필요하게 되고, 접촉고무(118)와 터치를 위한 돌출부(120)등의 부품이 추가된다.The present invention relates to a keyboard apparatus of an electronic musical instrument which simplifies the elastic device of a pushbutton keyboard in a keyboard musical instrument. As shown in (a) and (b) of FIG. In addition to the locking jaw, the protruding touch portion 111 and the contact rubber 112 and the insulator 113 for the touch is added, as well as the hinge portion 115 and the support 116 for supporting the flat spring 114 In the case of (b), the processing of the hole 119 for fixing the contact rubber 118 to the bracket 117 is required, and the contact rubber 118 and the protrusion 120 for the touch are required. ) Parts are added.

이와같은 종래의 건반장치는 그 구조가 복잡하여 작업성이 불량할뿐 아니라 수개의 생략 가능한 부품들이 필요하게 되므로 부품가공상이 난점 및 조립성, 경제성이 떨어저 생산성 증대의 저해요인이 되는 문제점이 있었다.Such a conventional keyboard device has a problem that the complexity of the structure is not only poor workability, but also several skippable parts are required, so that the difficulty in productivity due to difficulty in assembly, poor assembly and economical efficiency, is a factor of increasing productivity. .

본 고안은 이와같은 제결점을 해결하기 위하여 그 구조를 간단히 하고 탄력스프링을 이용하여 건반의 푸쉬버튼 작용이 용이하게 이루어질수 있도록 안출한 것으로써 이를 첨부한 도면에 의하여 상세히 설명하면 다음과같다.The present invention has been made to simplify the structure to solve such a defect and to push the key push button action of the key by using an elastic spring to be described in detail by the accompanying drawings as follows.

캐비넷(1)과 상부캐비넷(101) 사이의 내측으로는 가이드공(3)이 중앙에 형성된 브라켓(2)을 하면에, 접촉단자(901)가 상부에 형성된 PCB기판(4)이 부착되도록하여 설치하고, 상부캐비넷(101)과 브라켓(2)선단 사이에 탄성힌지부(6)가 끼여 고정되게 건반(5)을 설치하되, 건반(5)의 중앙부에 하향돌출 형성된 걸림턱(8)과 접촉단자(9)를 가진 돌출편(7)이 탄성력을 갖도록 스프링(10)이 끼워지게하여 브라켓(2)의 가이드공(3)에 삽입 설치하여서 조립구성된 것이다.The inner side between the cabinet 1 and the upper cabinet 101 has a bracket 2 formed at the center of the guide hole 3 so that the PCB 4 having the contact terminal 901 formed thereon is attached thereto. And install the keyboard 5 so that the elastic hinge portion 6 is sandwiched between the upper cabinet 101 and the end of the bracket (2), the locking jaw (8) formed to protrude downward in the center of the keyboard (5) and The spring 10 is fitted so that the protruding piece 7 having the contact terminal 9 has elastic force and is inserted into the guide hole 3 of the bracket 2 to be assembled.

이와같이 구성된 본 고안은 건반(5)상면을 화살표 방향으로 가압하여 누르게되면 건반(5)은 스프링(10)을 압축하면서 가상선 위치로 이동하게 된다.When the present invention configured as described above is pressed by pressing the upper surface of the keyboard 5 in the direction of the arrow, the keyboard 5 moves to a virtual line position while compressing the spring 10.

이때, 건반(5)의 돌출편(7)는 브라켓(2)의 가이드공(3)에 의하여 안내되는 상태로 하강하여 PCB기판(4)의 접촉단자(901)와 돌출편(7)의 접촉단자(9)를 맞닿는 상태로 접촉시키게 되므로 구성회로에 의하여 전자적으로 발진되는 음을 발생시키게 된다. 눌렀던 건반(5)을 놓게되면 스프링(10)의 탄력에 의하여 건반(5)은 본래의 위치로 상승하게 되는데 이때의 상승폭 제한은 건반(5)의 돌출편(7) 하단에 형성된 걸림턱(8)이 브라켓(2)의 가이드공(3) 하면에 걸리게 되어 그폭을 제어하게 된다.At this time, the protruding piece 7 of the keyboard 5 is lowered in the state guided by the guide hole 3 of the bracket 2 to contact the contact terminal 901 of the PCB board 4 with the protruding piece 7. Since the terminals 9 are brought into contact with each other, the sound generated electronically by the component circuit is generated. When the pressed key 5 is released, the key 5 is raised to its original position by the elasticity of the spring 10. At this time, the limit of the rising width is formed at the lower end of the protruding piece 7 of the key 5 8) is caught by the lower surface of the guide hole (3) of the bracket (2) to control the width.

이와같은 구성의 건반을 건반마다 음을 달리하도록 회로적으로 구성하여 설치하므로써 각각의 건반을 악보에 따라 누르게되면 멜로디 화음이 발진되게 되는 것이다.By constructing and installing a keyboard of such a configuration so that the notes vary from key to key, the melody chords are oscillated when each key is pressed according to the score.

이와같이 된 본고안은 건반(5)의 구성이 단일화되고 스프링(10)에 의한 탄성력을 이용하므로써 구조를 간편화하게되는 동시에 부품수를 내폭적으로 줄일수 있어서 조립 작업을 간편화하고 경제성을 갖게되어 생산성 증대에 기여할수 있게되는 특징을 지닌 것이다.In this way, the main structure of the keyboard 5 is unified and the structure is simplified by utilizing the elastic force by the spring 10, and the number of parts can be reduced internally, thereby simplifying the assembly work and economical efficiency, thereby increasing productivity. It is a characteristic that can contribute to.
