본 고안은 전기를 이용하여 여러가지 소리를 합성하는 전자오르간(전자 key board)에 관한 것이다.The present invention relates to an electronic organ (electronic key board) for synthesizing various sounds using electricity.
종래의 전자오르간은 건반을 한개씩 건반샤시에 조립하여 생산성이 낮고 또한 건반에 스프링을 사용함으로써 건반의 촉감이 고르지 않을뿐 아니라 스프링의 동작 소리가 간혹 발생되거나 스프링의 탄력이 약화될 경우 탄성에 의한 건반의 접점구조에 신뢰성이 없어 고장발생의 원인이 되는 단점이 있었다.Conventional electric organs have low productivity by assembling the keys one by one on the keyboard chassis, and by using the springs on the keys, not only the feel of the keys is uneven, but also the sound of the springs sometimes occurs or the elasticity of the springs weakens the springs. There is a disadvantage that the failure of the contact structure of the cause of the failure is not reliable.
본 고안은 따라서 이와 같은 단점을 개선하기 위하여 백건반과 흑건반을 일체로 제작하여 조립성 및 신뢰성을 높이도록 스프링 대신에 탄성복원력이 좋은 플라스틱을 이용하여 일체로 성형된 건반을 동작시키고 금속재 지지판을 사용하여 전체적인 건반구조의 동작을 정확하게 한 것으로 이하 첨부도면에 따라 상세히 설명하면 다음과 같다.In order to improve the above disadvantages, the present invention operates the keyboard integrally formed by using a plastic having good elastic restoring force instead of the spring to manufacture the white keyboard and the black keyboard integrally to increase the assemblability and reliability, and to support the metal support plate. When the operation of the overall keyboard structure using the accurate to be described in detail according to the accompanying drawings as follows.
제1도 내지 제3도에서와 같이 전자오르간의 캐비넷(1)에 백건반(3)과 흑건반(9)을 장치함에 있어 건반연결판(2)과 일체로 다수의 백건반(3)을 성형함으로써 백건반(3)과 건반 연결판(2) 사이에 얇은 탄성부(4)를 형성하고 상기 건반연결판(2)의 저면으로 수직하게 다수의 고정용보스(6)를 돌설시키되 이와 인접하여 체결공(7)을 형성하는 한편 건반연결판(2)의 전면으로 요홈(5)을 요입시켜 동일부재의 탄성부(10) 및 장방형 연결판(8)으로 형성된 흑건반(9)의 걸림턱(11)을 상기 건반연결판(2)의 요홈(5)에 조립함과 아울러 각 체결공(7)(12)을 일치한 다음 브라켓트(13)의 보스삽입공(14)과 나공(15)에 건반연결판(2) 저면의 고정용 보스(6)를 끼워 맞추고 나공(15)을 통하여 상기 건반(3)(9)의 연결판(2)(8)을 고정나사(16)로 부착한 것으로 도면중 미설명부호(17)은 보강돌기, (18)은 흑건반 걸림턱, (19)는 백건반의 접점누름턱, (20)은 PCB, (21)은 고무, (22)는 가동접점, (23)은 고정접점, (24)는 부직포이다.As shown in FIGS. 1 to 3, in order to install the white keyboard 3 and the black keyboard 9 in the cabinet 1 of the electronic organ, a plurality of back keyboards 3 are integrally formed with the keyboard connecting plate 2. By forming, a thin elastic portion 4 is formed between the back keyboard 3 and the keyboard connecting plate 2, and a plurality of fixing bosses 6 are vertically projected to the bottom of the keyboard connecting plate 2, but adjacent thereto. To form a fastening hole (7) while the recessed groove (5) in the front of the key connecting plate (2) to engage the black key (9) formed of the elastic member 10 and the rectangular connecting plate (8) of the same member Assemble the jaw (11) in the groove (5) of the keyboard connecting plate (2) and match each fastening hole (7) (12), and then the boss insertion hole (14) and the hole (15) of the bracket (13) Fit the fixing boss 6 of the bottom of the keyboard connecting plate 2 to the connecting plate 2 and 8 of the keyboard 3 and 9 with the fixing screw 16 through the hole 15. In the drawings, reference numeral 17 denotes a reinforcement protrusion, (18). The black keyboard latching jaw, 19 is a white keyboard contact pressing jaw, 20 is a PCB, 21 is rubber, 22 is a movable contact, 23 is a fixed contact, and 24 is a nonwoven fabric.
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
제1도에서와 같이 건반(3)(9)의 연결판(2)(8)은 캐비넷(1)의 절곡단부(1a)에 접촉되어 있는 상태에서 전자오르간을 연주할때 손가락으로 건반(3)(9)을 누르면 건반(3)(9)은 얇은 탄성부(4)(10)에 의해 하강하여 흑건반(9) 하면의 접점누름턱(19)이 브라켓트(13)에 고정된 고무(21)를 누르게 된다.As shown in FIG. 1, the connecting plates 2 and 8 of the keyboard 3 and 9 are connected to the keyboard 3 with the fingers when playing the electric organ in contact with the bent end 1a of the cabinet 1. (9), the keyboard (3) (9) is lowered by the thin elastic portion (4) (10) so that the contact pressing jaw (19) of the lower surface of the black keyboard (9) is fixed to the bracket ( 21).
이때 제3도에서와 같이 고무(21)내에 충전된 가동접점(22)이 PCB(20)상의 고정접점(23)과 통전되도록 한 것은 종래와 같으나 손가락을 건반(3)(9)으로 부터 떼면 건반연결판(2)과 일체로 된 백건반(3)과 연결판(8)에 연결된 흑건반(9)의 각 탄성부(4)(10)의 탄성에 의해 원복되며 접점구조도 원래의 상태로 복귀되어 통전이 멈추어 음이 발생되지 않는다.At this time, as shown in FIG. 3, the movable contact 22 filled in the rubber 21 is energized with the fixed contact 23 on the PCB 20. However, if the finger is removed from the keyboard 3, 9, It is restored by the elasticity of each elastic part 4, 10 of the white keyboard 3 integral with the keyboard connecting plate 2 and the black keyboard 9 connected to the connecting plate 8, and the contact structure is also in its original state. It returns to and stops energizing and no sound is generated.
이상 설명한 바와 같이 본 고안은 종래와 같이 건반에 스프링을 사용하지 않고 백건반과 흑건반을 일체로 형성하여 결합시킨 후 백건반의 연결판 저면에 돌설된 고정용 보스를 브라켓트의 보스삽입홈에 끼워 맞추고 고정나사로 조립함으로써 생산조립과정에서 파생되는 건반의 조립성을 획기적으로 해결하여 공정을 단축할 수 있고 백건반과 흑건반에 고정나사 또는 다른 조립부품을 사용하지 않아 조립시간이 절감되어 생산수율이 높으며 스프링에 의한 건반의 동작보다 동작의 정확성을 기할 수 있어 제품의 신뢰성을 향상시키고 A/S에 유리한 장점이 있는 것이다.As described above, in the present invention, the keyboard and the black keyboard are integrally formed by combining the keyboard and the black keyboard without using the spring as in the prior art, and then the fixing boss protruding from the bottom of the connecting board of the keyboard is inserted into the boss insertion groove of the bracket. By aligning and assembling with fixed screws, the assembly process of the keyboard derived from the production assembly process can be solved drastically, and the process can be shortened. The production time is reduced by eliminating the use of fixed screws or other assembly parts for the white and black keys. It is high and can improve the operation accuracy than the operation of the keyboard by the spring, which improves the reliability of the product and has the advantage of A / S.
