본 고안은 전자 건반악기의 건반장치에 관한 것으로, 특히 수평부에 다수개의 직립부가 형성된 판스프링으로 각 건반을 탄력지지하여 건반의 상하 움직임을 원활하게 하고 조립성을 향상한 전자 건반악기의 건반장치에 관한 것이다.The present invention relates to a keyboard apparatus of an electronic keyboard musical instrument, in particular, a key spring of the electronic keyboard musical instrument which smoothly supports the movement of the keyboard by supporting each key with a plate spring formed with a plurality of upright portions in the horizontal portion and improves assemblability. It is about.

종래 전자 건반악기의 건반장치는 제1도에 도시한 바와같이, 메인플레이트(1)의 돌기(1a)에 일단이 끼워지는 압축코일스프링(2)의 타단을 건반(3)의 내측돌기(3a)에 끼우고, 건반(3)의 걸림편(3b)이 메인플레이트(1)의 사각공(1b)에 끼워지며, 메인플레이트(1)에는 건반(3)의 누름돌부(3c)에 의하여 눌리어지는 러버키(4)가 삽입되고 인쇄회로기판(5)이 나사에 의해 메인플레이트(1)에 부착되어 있다.In the keyboard apparatus of the conventional electronic keyboard musical instrument, as shown in FIG. 1, the inner end 3a of the keyboard 3 is connected to the other end of the compression coil spring 2 whose one end is fitted into the projection 1a of the main plate 1. ), The engaging piece 3b of the keyboard 3 is fitted into the square hole 1b of the main plate 1, and the main plate 1 is pressed by the pressing protrusion 3c of the keyboard 3. The rubber key 4 is inserted and the printed circuit board 5 is attached to the main plate 1 by screws.

도면에서 3d는 건반(3)의 후단부에 형성된 홈을 보인것이고, 6은 고무스토퍼를 보인 것이다.In the figure, 3d shows a groove formed at the rear end of the keyboard 3, and 6 shows a rubber stopper.

이와같은 종래의 건반장치는 연주자가 건반(3)에 힘을 가하면 압축코일스프링(2)이 압축되면서 메인플레이트(1)의 수직한 면과 닿는 홈(3d)이 헌지점이 되어 동작되며 건반(3)의 누름돌부(3c)가 러버키(4)를 눌러 인쇄 회로기판(5)의 접점을 접속시키게 된다. 연주자가 다시 손을 떼면 압축코일스프링(2)의 복원탄성력에 의해 처음상태로 복귀된다.In this conventional keyboard device, when the player applies a force to the keyboard 3, the compression coil spring 2 is compressed, and the groove 3d contacting the vertical surface of the main plate 1 is operated as a dead spot. The pressing protrusion 3c of 3) presses the rubber key 4 to connect the contacts of the printed circuit board 5. When the player releases his hand again, it returns to the initial state by restoring elastic force of the compression coil spring 2.

그러나 종래의 건반장치는 건반(3)을 조립하면서 각 건반(3)에 압축코일스프링(2)을 하나씩 끼워 메인프레이트(1)에 조립하므로 조립작업이 매우 번거롭기 때문에 조립성이 저하되는 결함이 있었고, 연주자가 건반(3)의 누름돌부(3c) 상측부를 눌렀을때 건반(3)의 결합구조가 불안정하여 이탈되는 경우가 발생하는 문제점이 있었다.However, since the conventional keyboard device is assembled to the main plate 1 by inserting the compression coil springs 2 into each key 3 one by one while assembling the keyboard 3, assembling work is very cumbersome, there is a defect that the assemblability deteriorates. , When the player presses the upper side of the pressing protrusion 3c of the keyboard 3, there is a problem that the coupling structure of the keyboard 3 is unstable and is separated.

본 고안은 상기한 바와같이 종래의 결함을 해소하기 위하여 안출한 것으로 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve the conventional defects as described above and described in detail by the accompanying drawings as follows.

제2도 및 제3도에 도시한 바와같이, 메인플레이트(11)에 건반(12)이 탄력 결합되고 메인플레이트(11)의 수평부(11b)에는 상기 건반(12)의 누름돌기(12a)에 의해 눌리는 러버키(13)가 설치되며, 그 저부에는 인쇄회로기판(14)이 고정된 것에 있어서, 상기 메인플레이트(11)에 수평부(11a)(11b)(11c)와 수직부(11d)(11e)를 절곡 형성하고 일측 수직부(11d)에 형성한 다수개 통공(11f)에는 건반(12)의 내측돌부(12b)를 삽입하여 건반(12)의 내측돌부(12b) 하측에 형성한 홈(12c)을 통공(11f)의 하측변부(11g)에 접촉시키며, 수평부(15a)의 일측변부에 다수개의 직립부(15b)가 일정간격을 두고 절곡형성된 판스프링(15)을 상기 메인플레이트(11)의 수평부(11a)에 나사체결하고, 판스프링(15)의 다수개 직립부(15b)의 하단을 건반(12)의 내측돌부(12b) 상단에 형성한 걸림홈(12d)에 각각 삽입하는 한편, 메인플레이트(11)의 수직부(11e)에 형성한 통공(11h)에는 걸림편(12e)에서 내항으로 돌출형성한 수평부(12e')를 삽입하여서 된 것으로, 도면에서 미설명 부호 17은 판스프링(15)의 삽입공(15c)에 삽입되어 메인플레이트(11)의 나사공(11i)에 체결되는 고정나사를 보인 것이고, 16, 16'는 고무스토퍼를 보인 것이며, 12f는 멈춤돌부를 보인 것이다.As shown in FIGS. 2 and 3, the key 12 is elastically coupled to the main plate 11, and the push protrusion 12a of the key 12 is connected to the horizontal portion 11b of the main plate 11. The rubber key 13 which is pressed by is installed, and the bottom part of which the printed circuit board 14 is fixed, the horizontal parts 11a, 11b, 11c and the vertical part 11d on the main plate 11. ) 11e is formed in a plurality of through holes 11f formed in one vertical portion 11d, and the inner protrusion 12b of the keyboard 12 is inserted and formed below the inner protrusion 12b of the keyboard 12. The leaf spring 15 in which one groove 12c is in contact with the lower side portion 11g of the through hole 11f, and a plurality of upright portions 15b are bent at regular intervals on one side edge of the horizontal portion 15a. Is fastened to the horizontal portion (11a) of the main plate 11, the locking groove formed the lower end of the plurality of upright portion (15b) of the leaf spring (15) on the upper end of the inner protrusion (12b) of the keyboard 12 Insert each at 12d, In the hole 11h formed in the vertical portion 11e of the inflated plate 11, a horizontal portion 12e 'protruded into the inner port from the engaging piece 12e is inserted. The fixing screw is inserted into the insertion hole (15c) of the spring (15) is fastened to the screw hole (11i) of the main plate 11, 16, 16 'shows a rubber stopper, 12f shows a stopper will be.

이와같이된 본 고안은 연주자가 건반(12)의 힘을 가하면 그 건반(12)이 힌지홈(12c)을 기준하여 시계방향으로 회전하여 멈춤돌부(12f)가 고무스토퍼(16')에 접촉되면서 정지되고, 이때 건반(12)의 누름돌기(12a)가 러버키(13)를 눌러 인쇄회로기관(14)상의 접점을 접속시키며 내측돌부(12b)의 상향 이동에 따라 판스프링(15)이 변형된다.When the player applies the force of the keyboard 12 as described above, the key 12 rotates clockwise with respect to the hinge groove 12c to stop the stopper portion 12f in contact with the rubber stopper 16 '. At this time, the push protrusion 12a of the keyboard 12 presses the rubber key 13 to connect the contact on the printed circuit engine 14, and the leaf spring 15 is deformed as the inner protrusion 12b moves upward. .

한편, 연주자가 손을 떼면 판스프링(15)의 복원력에 의하여 초기상태로 복귀된다.On the other hand, when the performer releases his hand, it returns to the initial state by the restoring force of the leaf spring 15.

이와같이된 본 고안은 건반(12)을 탄력지지하는 판스프링(15)이 힌지홈(12c)을 기준하여 내측부분인 내측돌부(12b)의 상측에 설치되고, 걸림편(12e)의 내향 수평부(12e')가 힌지홈(12c)의 외측부에서 통공(11h)에 걸리어 있으므로 건반(12)이 안정하게 지지되며, 현지점이 안정하고 정확하게 유지되어 연주시에 건반(12)이 이탈될 우려가 없다. 뿐만아니라 각 건반(12)은 단일체인 판스프링(15)에 의해서 탄지되는 것이므로 조립성이 월등히 향상되고 원가가 절감된다.The present invention as described above is installed on the upper side of the inner projection 12b which is an inner portion with respect to the hinge groove 12c is provided with a leaf spring 15 for supporting the keyboard 12, the inward horizontal portion of the locking piece 12e Since the 12e 'is caught by the through hole 11h at the outer side of the hinge groove 12c, the keyboard 12 is stably supported, and the local point is stably and accurately maintained so that there is no fear of the keyboard 12 being dislodged during performance. . In addition, since each key 12 is carried by the single-piece leaf spring 15, assembling performance is greatly improved and cost is reduced.

따라서 본 고안은 건반이 원활하고 안정되게 동작되어 제품의 신뢰도 향상에 기여하고 경쟁력 향상에 기여하는 이점이 있다.Therefore, the present invention has a merit that the keyboard operates smoothly and stably, contributing to improving the reliability of the product and improving the competitiveness.
