본 고안은 전자악기에 사용되는 건반에 관한 것으로서, 특히 건반의 힌지를 구성함에 있어서 건반 힌지홀에 고정핀을 창착하여 보다 원활하고 효과적인 힌지역할을 할수 있도록 개량한 것이다.The present invention relates to a keyboard used for electronic musical instruments, and in particular, in the hinge of the keyboard, a fixing pin is installed in the keyboard hinge hole to improve a smooth and effective hinge area.
종래에 사용되어온 전자악기의 건반은 제 1 도에 도시된 바와같이 스프링(21)으로 탄지되는 건반(22)의 중단부에 돌출부(23)를 형성하고 상기 돌출부(23) 하단에 도전막(24)을 부착한 탄성체(25)를 설치하고 본체 하우징에 설치된 브라켓(26)에 지지되는 PCB기판(27)에 형성된 회로 패턴의 접점(28)을 압압하면 건반(22)은 힌지부(29)를 중심으로 하단의 돌출부(23)가 하향으로 내려오면서 도전막(24)이 접점(28a,28b)을 서로 접속시켜 주므로서 회로를 연결하여 도시하지 않은 음 발생장치에 신호를 출력하여 음을 재생할 수 있게 된다.The keyboard of an electronic musical instrument, which has been used in the past, forms a protrusion 23 at a stop of a key 22 supported by a spring 21 and a conductive film 24 at the bottom of the protrusion 23 as shown in FIG. 1. When the elastic body 25 to which is attached) is installed and the contacts 28 of the circuit pattern formed on the PCB substrate 27 supported by the bracket 26 installed on the main body housing are pressed, the keyboard 22 opens the hinge portion 29. As the projection 23 at the bottom of the center descends downward, the conductive film 24 connects the contacts 28a and 28b to each other, thereby connecting a circuit and outputting a signal to a sound generator (not shown) to reproduce sound. Will be.
그러나 이러한 장치는 건반(22)을 누르면 후방의 스프링(21)이 복원력을 받으면서 건반(22)이 하강하게 되어 돌출부(23)가 도전막(24)를 누르게되고 여기에 마련된 접점이 PCB기판(27)에 마련된 접점(28a,28b)에 접촉하여 전자적으로 발진된 음을 발생하고 눌렸던 건반(22)을 놓으면 복원스프링(21)에 의해 처음의 상태로 돌아간다. 그러나 건반 힌지부(29)는 단순히 프레임(30)의 고정구(31)에 체결되어있어 건반의 지지물의 역할을 해왔다.However, in such a device, when the key 22 is pressed, the key 22 is lowered while the spring 21 at the rear receives the restoring force, so that the protrusion 23 presses the conductive layer 24, and the contacts provided therein are the PCB substrate 27. When the keyboard 22, which has been pressed by generating the electronically oscillated sound and released by contacting the contacts 28a and 28b provided at the step, is returned to the initial state by the restoring spring 21. However, the keyboard hinge portion 29 is simply fastened to the fasteners 31 of the frame 30 to serve as a support of the keyboard.
따라서 간반 힌지부(29)는 항상 스프링(21)의 힘을 받고 있으며 단순한 고정구(30)에 의해 걸려 있어 간반을 계속 강한 힘을 가했을 때 건반힌지부가 파괴되는 경우가 생기므로 건반 힌지부가 상당히 취약할 뿐 아니라 원활한 힌지 역할을 하지 못하여 건반힌지부의 분해 및 조립시에 스프링의 힘을 받으면서 건반 힌지부(29)를 고정시켜야하고, 또한 건반 프레임에 건반 선단의 일부가 걸림턱의 구조로 장착되어있어, 건반 사출 성형에 있어서도 많은 문제점이 있었다.Therefore, the banban hinge portion 29 is always under the force of the spring 21 and is hung by a simple fastener 30, the key hinge portion may be destroyed when the strong force is continuously applied to the banban, so that the key hinge portion may be considerably weak. In addition, the key hinge portion 29 must be fixed while the spring hinge portion is disassembled and assembled during the disassembly and assembly of the key hinge portion, and a part of the key tip is mounted to the key frame as a locking jaw structure. There have been many problems in keyboard injection molding.
본 고안은 상기와 같은 문제점을 해소하기 위하여 안출된 것으로서 본 고안에서는 건반의 힌지부를 구성함에 있어서 건반의 걸림턱을 없애고 힌지부에 인장스프링과 고정대의 고정핀을 결합하여 건반의 누르는 힘에 따라 대응하는 스프링의 인장력을 작용토록하여 힌지부의 역할을 할 수 있도록 함을 본 고안의 목적으로 한다.The present invention has been devised to solve the above problems, in the present design to remove the locking jaw of the keyboard in the hinge portion of the keyboard and to combine the tension spring and the fixing pin of the hinge to the hinge to respond according to the pressing force of the keyboard It is an object of the present invention to act as a hinge portion by the tension force of the spring to act.
상기와 같은 목적을 수행하기 위한 본 고안의 실시예를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.An embodiment of the present invention for carrying out the above object will be described in detail with reference to the accompanying drawings.
우선 제 2 도를 참조하여 본 고안의 구성을 설명하면 건반(1)의 힌지부(6)중앙에는 상광하협된 힌지홀(11)을 형성하고 고정대(8)중앙부에 형성된 원기둥의 고정핀(9)을 중심으로 뒷쪽은 평면이고 앞쪽은 하향으로 절곡된 고정대(8)를 프레임(2)에 고정시키고 고정대(8)의 상부면에 펠트(10)를 설치한 고정대(8)의 고정핀(9)을 힌지홀(11)에 삽입하고 건반의 후방을 인장스프링(7)으로 탄지하며 프레임(2)의 하단에 조립된 PCB기판(3)에는 내부에 접점이 형성된 접촉고무(5)와 상반되는 건반의 중앙하단에 접점의 돌출부(4)가 형성된 것으로서 도면중 미설명부호 12은 쿠숀, 13은 캐비넷이다.First, referring to FIG. 2, the structure of the present invention will be described. In the center of the hinge portion 6 of the keyboard 1, a hinge hole 11 having a vertical light narrowing is formed, and a fixing pin 9 of a cylinder is formed in the center of the fixing stand 8. Fixing pin (9) of the fixing bracket (8) fixed to the frame (2) fixed to the frame (2) and the front is bent downward in the front and the felt 10 is installed on the upper surface of the fixing bracket (8) ) Is inserted into the hinge hole 11 and the back of the keyboard is held with a tension spring (7), and the PCB board (3) assembled at the bottom of the frame (2) is opposed to the contact rubber (5) having a contact therein. The protrusion 4 of the contact is formed at the bottom center of the keyboard, and reference numeral 12 in the figure is a cushion and 13 is a cabinet.
이와 같이 구성된 본 고안의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.
제 4 도를 참조하여 설명하면 우선 건반(10)을 압압하면 힌지 역할을 하는 고정대(8)의 고정핀(9)을 중심으로 건반(1)이 회동하면서 하향으로 내려간다.Referring to FIG. 4, first, when the key 10 is pressed, the key 1 rotates around the fixing pin 9 of the fixing stand 8 that serves as a hinge and moves downward.
이때 고정핀(9)을 중심으로 상광하협된 힌지홀(11)에 의해 건반이 하향으로 내려갈 수 있게 되고 고정대(8)의 절곡된 부위에 형성된 펠트(10)까지 내려오게되며 인장스프링(7)의 탄발력이 손끝의 타건감각에 의하여 돌출부(4)가 PCB기판(3)에 접점이 형성되며 접촉고무(5)와 부드럽게 접촉하여 접촉고무 내부의 도전막과 접점이 도통되어 전류를 흐를 수 있도록 하여 도시하지 않은 회로에 의하여 음을 발생하도록 한다.At this time, the keyboard can be lowered downward by the hinge hole 11 which is normally upper and lower with respect to the fixing pin 9 and descends to the felt 10 formed at the bent portion of the fixing table 8 and the tension spring 7. The resilience force of the fingertips causes the protrusion 4 to form a contact point on the PCB 3 by the touch-sensing of the fingertip, and gently contacts the contact rubber 5 so that the conductive film and the contact inside the contact rubber can conduct current. To generate sound by a circuit (not shown).
또한 건반이 더이상 하강 하지 못하도록 고정대(8)의 절곡된 경사면과 힌지홀(11)의 경사면에 고정핀(9)에 의해 더이상 하강하지 않고 프레임(2)에 설치된 쿠숀(12)에 건반(1)이 당접되어 완충작용을 하므로 타건시터치 감각을 좋게 한다.In addition, the key (1) on the cushion (12) installed in the frame (2) is no longer lowered by the fixing pin (9) on the bent inclined surface of the holder 8 and the inclined surface of the hinge hole (11) so that the keyboard no longer lowers. This abutment acts as a buffer so that you feel better at touch.
이와같은 상태에서 건반을 압압하던 힘을 제거하게 되면 후방에 형성된 인장스프링(7)의 복원력에 의해 힌지부(6)의 고정핀(9)이 힌지홀(11)의 벽면에 당접되어 더이상 상향하지 않게 되고 건반이 처음 상태의 원위치로 복귀하게 된다.When the force that presses the key in such a state is removed, the fixing pin 9 of the hinge part 6 abuts the wall surface of the hinge hole 11 by the restoring force of the tension spring 7 formed at the rear side, so that it is no longer upward. The keyboard will then return to its original position.
상기와 같은 본 고안에 의하면 인장스프링의 완충작용에 의해 접점의 마모를 미연에 방지하여 접점의 수명을 연장하고, 건반을 계속 타건할때나 강한힘을 가했을 때에도 힌지홀과 고정핀으로 힌지역할을 하므로 파괴될 염려가 없고 건반의 동작이 더욱 원활하며 건반의 조립 및 분해가 용이한 이점이 있다.According to the present invention as described above, by the buffering action of the tension spring to prevent the wear of the contact in advance to extend the life of the contact, even when the key is continuously pressed or applied a strong force to the hinge hole and the pin Therefore, there is no fear of destruction, the operation of the keyboard is more smooth, and there is an advantage of easy assembly and disassembly of the keyboard.
