본 고안은 전자오르간에서 건반을 누름에 따라 접점이 접속되며 인쇄회로기판으로 전하도록 한 것으로, 특히 본체의 돌기에 홈이 끼워져 이를 중심으로 상하 탄동을 하는 건반의 하측에 구비한 작동편이 가이더내에서 코일스프링의 탄성을 받은 슬라이드편을 밀어주도록 하여 이의 하단에 부착된 가동 접점이 접속 인쇄회로기판의 접점과 접속되도록 함으로써 인쇄회로기판으로 신호를 보내어 음을 발생하도록 한 전자오르간의 접점 구동장치에 관한 것이다.According to the present invention, the contact point is connected to the electronic organ as the key is pressed and transmitted to the printed circuit board. In particular, the operation piece provided on the lower side of the keyboard having a groove inserted in the protrusion of the main body and moving up and down is centered in the guider. A contact drive device for an electronic organ that sends a signal to a printed circuit board to generate a sound by pushing a slide piece that is elastically coiled so that the movable contact attached to the lower end thereof is connected to the contact of the connected printed circuit board. will be.

종래에는 건반이 판 스프링의 탄성을 받아 상하로 탄동하면서 하측에 구비된 접점을 접속시켜주도록 하였으나 이는 판 스프링을 설치하는데에 따른 조립상의 문제점이 있으며 장기간 사용시에는 판스프링의 탄성력이 자주 누르는 건반과 자주 누르지 않는 건반에 따라 차이가 나서 음이 고르지 않고 흰건반과 검은건반은 축과의 회전거리가 서로 다르므로 누르는 압력이 달라지게 되어 불편한 점이 있음은 물론 접점부의 동작이 불확실하여 전자오르간 자체의 성능에도 지장을 주는 등의 단점이 있었다.Conventionally, the keyboard receives the elasticity of the leaf spring and allows it to connect up and down the contacts provided on the lower side, but there is a problem in assembling by installing the leaf spring, and the elastic force of the leaf spring is frequently pressed for a long time. The sound is uneven because the key does not press, and the white and black keys have different rotational distances between the shafts, so the pressing pressure is different, which is inconvenient. There were disadvantages such as disturbing.

이와같은 종래의 단점을 보완하기 위한 본 고안은 선단이 본체의 지지부에 얹혀지고 홈이 돌기에 끼워진 건반의 작동편이 가이더내에서 코일스프링의 탄성을 받는 슬라이드핀의 돌턱을 밀어주도록 하고, 가이더의 나사공에 나사조입된 볼트에 의해 이동하는 밀편으로 탄성력이 조절되는 코일스프링이 탄지된 슬라이드편의 하단에 부착한 가동접점이 접속 인쇄회로기판상의 접점과 접속 또는 단락되면서 인쇄회로기판으로 신호를 보내 음을 발생하도록 한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다. 선단(2-1)이 본체(1) 지지부(1-1)에 얹혀지고 상측의 돌기(1-2)에 홈(2-2)이 끼워져 이를 중심으로 왕복동하며 하측의 안내공(1-3)에 삽입된 걸림턱(2-3)에 의해 작동거리가 제한되는 건반(2) 하단중앙부에 ㄴ자형상으로 구성된 작동편(2-4)을 일체로 구비시키고, 이의 작동편(2-4)으로 가이더(4)내에 스프링(7)에 의하여 전향으로 탄력 설치된 슬라이드편(3)의 돌턱(3-1)을 밀어주도록 하고, 이때 슬라이드편(3)의 탄력을 가이더(4) 후면에 구비되 나사공(4-1)에 나사 결합된 조절볼트(5)와 협동하는 밀편(6)으로 조절케 구성하고 있다.The present invention for compensating the above disadvantages is to allow the working piece of the keyboard, whose tip is placed on the support of the main body and the groove is inserted into the protrusion, to push the stone jaw of the slide pin receiving the elasticity of the coil spring in the guider. The movable contact attached to the lower end of the slide piece where the elastic spring is controlled by the bolt spring screwed into the slot is moved or shorted with the contact on the connection printed circuit board and sends a signal to the printed circuit board. It will be described, as described in detail by the accompanying drawings as follows. The tip 2-1 is placed on the support 1-1 of the main body 1, and the groove 2-2 is fitted into the upper projection 1-2 so as to reciprocate about it and the lower guide hole 1-3. In the central part of the lower end of the keyboard (2) that the operating distance is limited by the engaging jaw (2-3) is inserted into the integrally provided with the operating piece (2-4) consisting of the B-shaped, the working piece (2-4) In order to push the protrusion 3-1 of the slide piece 3 elastically installed forwardly by the spring 7 in the guider 4, and the elasticity of the slide piece 3 is provided on the rear of the guider 4. The adjustment bolt 5 is screwed into the screw hole 4-1, and the adjustment piece 5 is cooperatively comprised.

그리고 상기 슬라이드편(3)의 하단에는 돌기(3-2)을 일체로 구비하여 본체(1)의 삽입홈(1-4)에 설치된 인쇄회로기판(9)과 연결되어 신호를 전하는 접속 인쇄회로기판(8)의 접점(8-1)과 접하도록 한 것이다.In addition, the lower end of the slide piece (3) is provided with a projection (3-2) integrally connected to the printed circuit board (9) installed in the insertion groove (1-4) of the main body 1 is connected to the printed circuit This is in contact with the contact 8-1 of the substrate 8.

다시 설명하면 통상의 박막(Membrane) 스위치와 같이 동작을 이룬다.In other words, it works like a conventional membrane switch.

이와같은 본 고안은 사용자가 전자오르간을 사용하기 위하여 건반(2)을 누르면 본체(1)의 지지부(1-1)에 선단(2-1)이 얹혀지고 돌기(1-2)에 홈(2-2)이 끼워진 채 이를 중심으로 회전하며 하단의 작동편(2-4)이 슬라이드편(3)의 돌턱(3-1)을 밀어주게 된다.In the present invention, when the user presses the keyboard 2 to use the electronic organ, the tip 2-1 is placed on the support 1-1 of the main body 1 and the groove 2 is provided on the protrusion 1-2. -2) is rotated around it while the operating piece (2-4) of the lower end to push the stone projection (3-1) of the slide piece (3).

그러면 가이더(4)내에서 스프링(7)의 탄성을 받으며 작동공(4-2)에서 왕복동하는 슬라이드편(3)의 하단에 부착된 돌기(3-2)가 후향으로 밀려 이동함과 동시에 접속 인쇄회로기판(8)의 접점(8-1)를 누르어 접속을 이루어 인쇄회로기판(9)으로 신호를 보내줌으로써 적절한 음이 발생하도록 한 것이다.Then, the projection 3-2 attached to the lower end of the slide piece 3 reciprocating in the operating hole 4-2 while receiving the elasticity of the spring 7 in the guider 4 is pushed backwards and connected at the same time. By pressing the contact 8-1 of the printed circuit board 8 to make a connection, a signal is sent to the printed circuit board 9 so that an appropriate sound is generated.

그리고 이때 가이더(4)의 나사공(4-1)에 나사 조임된 볼트(5)을 조이거나 풀면서 밀편(6)을 이동시켜 코일스프링(7)의 탄성거리를 조절하도록 함으로써 접속인쇄회로기판(8)의 접점(8-1)과 접하는 가동접점(3-2)이 하단에 부착된 슬라이드편(3)의 밀편(3-1)을 밀어주는 건반(2)의 누르는 압력이 항상 일정해지도록 임의로 조절할 수 있도록 한 것이다.At this time, the connection printed circuit board is controlled by adjusting the elastic distance of the coil spring 7 by moving the contact piece 6 while tightening or loosening the bolt 5 fastened to the screw hole 4-1 of the guider 4. The pressing pressure of the keyboard 2 which pushes the push piece 3-1 of the slide piece 3 which the movable contact 3-2 which contact | connects the contact 8-1 of (8) attached to the lower end is always constant It can be adjusted arbitrarily to lose.

이와같이 본체(1)의 돌기(1-2)에 홈(2-2)이 끼워진 채 상하로 탄동하는 건반(2)의 하측에 작동편(2-4)을 형성하여 가이더(4)내에서 볼트(5)로 밀편(6)을 이동하며 탄성력이 조절되는 코일스프링(7)이 탄지된 슬라이드핀(3)의 밀편(3-1)을 밀어주도록함으로써 이의 하단에 부착된 돌기(3-2)이 접속 인쇄회로기판(8)의 접점(8-1)과 접하면서 인쇄회로기판(9)으로 신호를 보내 음이 발생하도록 한 것으로, 구성이 간단하고 작동이 안정됨은 물론 볼트(5)로 코일스프링(7)의 탄성력을 조절하며 항상 일정한 압력으로 작동하도록 한 것이다.In this way, the operation piece 2-4 is formed on the lower side of the keyboard 2, which swings up and down, with the groove 2-2 inserted in the protrusion 1-2 of the main body 1, and the bolt in the guider 4 is formed. The projection 3-2 attached to the lower end thereof by moving the push piece 6 to push the push piece 3-1 of the slide pin 3 on which the elastic force is adjusted to move the push piece 6 to (5). The sound is generated by sending a signal to the printed circuit board 9 while being in contact with the contact 8-1 of the connected printed circuit board 8, and the configuration is simple, the operation is stable, and the coil is wound by the bolt 5 To adjust the elastic force of the spring (7) is to always operate at a constant pressure.
