본 고안은 전자오르간의 건반장치에 관한 것으로 특히 건반을 누를 때 중후한 터치감각을 느낄 수 있도록 하는데 적합한 전자오르간의 건반장치에 관한 것이다.The present invention relates to an electronic organ keyboard device, and more particularly, to an electronic organ keyboard device suitable for making a heavy touch sense when a key is pressed.

종래 전자오르간의 건반장치는 제3도에서와 같이 샤시(20)에 축지된 건반(21)을 누르면 힌지점(22)을 축으로 회전되면서 건반(21) 밑면의 스프링 걸림대(23)에 일단이 고정된 판스프링(24)이 굽혀짐에 따라 건반(21)이 하강되고 손을 놓으면 판스프링(24)의 복원력에 의하여 복구된다.In the conventional electronic organ keyboard device, as shown in FIG. 3, when the key 21 held by the chassis 20 is pressed, the end of the key holder 21 is rotated about the hinge point 22 by the axis. As the fixed leaf spring 24 is bent, the keyboard 21 is lowered and released by the restoring force of the leaf spring 24 when the hand is released.

여기서 건반(21)의 수직운동은 제동편(25) 및 제동구멍(26)에 의하여 제한된다.Here, the vertical movement of the keyboard 21 is limited by the braking piece 25 and the braking hole 26.

그러나 이와 같은 종래의 건반장치는 판스프링(24)의 탄성력에 의존하여 조작되므로 건반(21)을 누를 때 실제의 오르간을 연주하는 경우와 상이한 터치감을 느끼게 되고 건반(21) 조작시의 중후한 감각을 확보할 수 없는 문제점이 있었다.However, since such a conventional keyboard device is operated depending on the elastic force of the leaf spring 24, when the key 21 is pressed, a feeling of touch different from that of playing an actual organ is felt, and a solid sense when operating the key 21 is performed. There was a problem that can not be secured.

본 고안은 이와 같은 종래의 문제점을 해결하기 위하여 건반과 연동되는 래크 및 래크의 제동을 위한 탄성수단을 구비하여 건반을 누를 때 연주자가 중후한 터치감을 느낄 수 있도록 한 전자오르간의 건반장치를 제공하는데 그 목적이 있는 것으로 첨부된 도면에 의하여 본 고안의 구성 및 작용효과를 상세히 설명하면 다음과 같다.The present invention provides an electronic organ keyboard device that allows the player to feel a heavy touch when the key is pressed by providing the rack and the elastic means for braking the rack in order to solve such a conventional problem. Referring to the configuration and operation of the present invention in detail by the accompanying drawings as the purpose is as follows.

먼저 본 고안의 구성부터 설명하면 제1도 및 제2a,b도에서와 같이 건반 고정판(1)의 후측판(1′)과 지지체(2)로 건반(3)의 후측을 지지하고, 건반(3) 하부의 고정판(1)에 형성된 안내홈(4)에 작동판(5)과 일체로 된 가동체(6)이 끼워져서 전후진 되게 하고, 상기 작동판(5) 앞쪽의 만곡면(7)은 건반(3) 앞쪽의 반원형 돌출부(8)와 접촉하게 작동판(5) 후측 밑면에 형성된 래크(9)는 고정축(10)에 끼워진 기어(11)와 맞물리고, 상기 기어(11)의 일측면에 형성된 걸림턱(11′)과 고정판(1)에 압축스프링(12)을 걸어서 된 것이다.First, the configuration of the present invention will be described as shown in FIGS. 1 and 2a and b to support the rear side of the keyboard 3 with the rear plate 1 'and the support 2 of the keyboard fixing plate 1, and the keyboard ( 3) The movable body 6 integrated with the operating plate 5 is inserted into the guide groove 4 formed in the lower fixing plate 1 so as to be moved forward and backward, and the curved surface 7 in front of the operating plate 5 is provided. The rack 9 formed on the bottom surface of the rear side of the operating plate 5 in contact with the semicircular projection 8 in front of the keyboard 3 is engaged with the gear 11 fitted to the fixed shaft 10, and the gear 11 Hanging compression spring 12 to the locking step (11 ') and the fixed plate (1) formed on one side of the.

도면중 미설명부호 13은 기어(11) 고정용 E링, 14는 지지체(2)가 끼워지는 홈, 15는 축(10) 고정편이다.In the figure, reference numeral 13 is an E-ring for fixing the gear 11, 14 is a groove into which the support 2 is fitted, and 15 is a shaft 10 fixing piece.

이와 같이 구성된 본 고안의 작용효과는 제1도 및 제2a도에서와 같이 건반(3)이 눌리지 않는 경우에는 반원형 돌출부(8)가 작동판(5)의 만곡면(7) 상단과 접촉되고 가동체(6)는 안내홈(4) 일측에 위치된다.The effect of the present invention configured as described above is that when the key 3 is not pressed as shown in FIGS. 1 and 2a, the semi-circular protrusion 8 contacts the upper end of the curved surface 7 of the operating plate 5 and is movable. Sieve 6 is located on one side of the guide groove (4).

그러나 건반(3) 단부를 누르게 되면 제2b도에서와 같이 건반(3)이 후측판(1′)과 지지체(2) 사이에서 지지된 지점을 축으로 소정각도 회전되므로 돌출부(8)에 의하여 만곡면(7)을 따라 하강된다.However, when the end portion of the key 3 is pressed, the key 3 is curved by the protrusion 8 because the key 3 is rotated at an angle around the point supported between the rear plate 1 'and the support 2 as shown in FIG. It is lowered along the surface 7.

따라서 작동판(5)이 밀리게 되므로 가동체(6)가 안내홈(4) 일단으로부터 그 타단으로 진입하게 되고 이와 동시에 래크(9)와 맞물린 기어(11)가 스프링(12)의 탄성력을 극복하고 회전된다.Therefore, since the operating plate 5 is pushed, the movable body 6 enters the other end from the one end of the guide groove 4, and at the same time, the gear 11 engaged with the rack 9 overcomes the elastic force of the spring 12. And rotate.

즉, 건반(3)을 누르는 경우 래크(9) 및 기어(11)와 스프링(12)에 의한 건반(3)에서 손을 떼면 스프링(12)의 탄성복원력에 의하여 기어(11)가 역회전되므로 래크(9)로 동력이 전달되어 가동체(6)와 건반(3)은 제2a도에서와 같은 위치로 복구된다.That is, when the key 3 is pressed, the gear 11 is reversed by the elastic restoring force of the spring 12 when the hand is released from the rack 9 and the key 11 by the gear 11 and the spring 12. Power is transmitted to the rack 9 to restore the movable body 6 and the keyboard 3 to the same positions as in FIG. 2A.

이상에서 설명한 바와 같이 본 고안에 의하면 전자오르간의 건반조작시 터치감에 중후감과 제동에 따른 연주액션의 실감을 확보할 수 있는 효과가 있다.As described above, according to the present invention, there is an effect that a feeling of playing action according to a profound feeling and braking can be secured to a touch feeling when an electronic organ is operated.
