본 고안은 디지탈 피아노(Digital Piano) 덮개의 자동개폐구조에 관한 것으로, 더욱 상세하게는 전후 방향 미끄럼방식으로 개폐되는 디지탈피아노의 덮개를 자동으로 개폐시킬 수 있도록 한 것이다.The present invention relates to the automatic opening and closing structure of the cover of the digital piano (Digital Piano), and more particularly to the automatic opening and closing of the cover of the digital piano that is opened and closed in the forward and backward direction.

일반적으로, 디지탈 피아노의 덮개는 업라이트 피아노(Up-Right Piano)에서와 같이 상하로 여닫히는 방식과 전후로 슬라이드되면서 여닫히는 방식으로 대별되는 바, 후자인 전후로 슬라이드되면서 열고 닫히는 피아노덮개는 연주자가 일일이 연주전에는 덮개를 뒤쪽으로 밀어 열어야하고, 연주를 끝낸 다음에는 덮개를 앞으로 당겨 닫아야 됨에 따라 그 개폐동작이 불편하다는 문제가 있었다.In general, the cover of a digital piano is divided into a method of opening and closing, such as up and down, and slides back and forth, as in an upright piano, and a piano cover that is opened and closed while the latter slides back and forth is played by the player. Previously, the cover had to be pushed to the rear to open, and after finishing the performance, the cover had to be pulled forward and closed.

본 고안은 이와 같은 종래의 문제점을 개선하기 위한 것으로, 디지탈피아노의 콘트롤패널 하부에 이송랙을 고정설치하고, 덮개의 후단양쪽에는 별도의 구동모터와 맞물려 회동하는 이송기어를 설치하여 연주자가 스위치를 조작하는 단순한 동작에 의하여 덮개가 자동적으로 전후진 구동될 수 있도록 한 새로운 형태의 디지탈 피아노 덮개의 자동개폐 구조를 제공하고자 하는데 목적이 있다.The present invention is to improve such a conventional problem, fixedly installed in the lower transfer panel of the control panel of the digital piano, the rear end of the cover by installing a transfer gear that rotates in engagement with a separate drive motor to the player to switch An object of the present invention is to provide an automatic opening and closing structure of a digital piano cover of a new type in which the cover can be automatically driven back and forth by a simple operation.

이하, 첨부된 도면에 의하여 본 고안을 보다 상세히 설명한다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

본 고안은 제 1 도 및 제 2 도에 도시된 바와 같이 디지탈 피아노(10)의 콘트롤 패널(12) 하부에 이송랙(14)을 고정설치하고, 덮개(16) 후단에는 별도의 구동모터(18)와 맞물려 회동하는 회동축(20)을 설치하되, 상기 회동축(20)의 양단에는 상기 이송랙(14)과 맞물리는 이송기어(22)를 고정설치하여 된 특징을 갖는다.The present invention is fixed to the transport rack 14 in the lower portion of the control panel 12 of the digital piano 10, as shown in Figures 1 and 2, and a separate drive motor 18 at the rear end of the cover 16 ) Is provided with a rotating shaft 20 to rotate in engagement with the rotating shaft 20, the transfer gear 22 to be engaged with the transfer rack 14 is fixed to both ends of the rotating shaft 20.

이와 같은 본 고안에서 콘트롤패널(12)의 하부에 설치되는 이송랙(14)은 제 1 도에 도시된 바와같이, 덮개(16)보다 아래쪽에 설치하여 덮개(16)의 전후진 구동시 장애가 되지 않도록 하며, 덮개(16)후단에는 회동축(20)을 끼워 지지하기 위한 축받침편(24) 1쌍을 일정한 간격으로 돌출시키는 한편, 상기 회동축(20)상에는 구동모터(18)의 동력을 받아 회동축(20)을 구동시켜주는 동력전달기어(26)를 고정설치한다.In the present invention, the transfer rack 14 installed at the lower portion of the control panel 12 is installed below the cover 16, as shown in FIG. 1, so that it does not become an obstacle when the cover 16 is driven forward and backward. At the rear end of the cover 16, a pair of bearing members 24 for holding the pivot shaft 20 are projected at regular intervals, while the driving motor 18 is driven on the pivot shaft 20. Receives and installs a power transmission gear 26 that drives the pivot shaft 20.

한편, 상기한 이송랙(14)의 후단과 전단에는 각각 구동모터(18)와 전기적으로 연결된 통상의 리미트 스위치(Limit Switch;도시되지 않음)를 설치하여 덮개(16)의 개방동작과 닫힘동작이 완료된 상태에서 구동모터(18)의 회전을 제어하도록 하며, 제품본체외부 일정위치에는 스위치(도시되지 않음)를 설치하고 이를 상기 구동모터(18)와 전기적으로 연결한다.On the other hand, the rear end and the front end of the transfer rack 14 is provided with a conventional limit switch (not shown) electrically connected to the drive motor 18, respectively, to open and close the lid 16 operation. The rotation of the drive motor 18 is controlled in the completed state, and a switch (not shown) is installed at a predetermined position outside the product body and is electrically connected to the drive motor 18.

이와 같은 본 고안의 작용은 다음과 같다.The operation of the present invention as follows.

즉 제 3a 도에 도시된 바와 같이 연주가가 피아노를 연주하고자 하는 경우 스위치를 누르면, 스위치와 전기적으로 연결된 구동모터(18)가 한쪽방향으로 회전하면서 덮개(16)후단에 설치된 회동축(20)상의 동력전달기어(26)를 구동시킴에 따라 회동축(20)이 회동하게 되고, 이에 따라 회동축(20) 양단에 설치된 이송기어(22)가 이송랙(14)을 따라 후방으로 이송되어 덮개(16)가 개방된다.That is, when the player presses the switch as shown in FIG. 3A, the driving motor 18 electrically connected to the switch rotates in one direction, and the rotary shaft 20 installed on the rear end of the cover 16 is rotated. As the power transmission gear 26 is driven, the rotation shaft 20 rotates, and accordingly, the transfer gear 22 installed at both ends of the rotation shaft 20 is transferred backward along the transfer rack 14 to cover the cover ( 16) is opened.

이같은 상태로부터 덮개(16)를 닫고자 하는 경우에 스위치를 다시 누르면 제 3a 도에 도시된 바와 같이, 구동모터(18)가 개방시와는 반대방향으로 회전하여 회동축(20)이 반대방향으로 회동되고 이송기어(22)가 이송랙(14)을 타고 앞으로 이동하여 덮개(16)가 닫히는 것이다.When the cover 16 is to be closed from such a state, pressing the switch again, as shown in FIG. 3A, causes the rotational motor 20 to rotate in the opposite direction as shown in FIG. The cover 16 is closed by being rotated and the transfer gear 22 moves forward by the transfer rack 14.

상기와 같은 덮개(16)의 개폐작동시에 덮개(16)가 이송랙(14) 후단이나 전단에 다다르면 리밋트 스위치(도시되지 않음)접촉하여 구동모터(18)에 인가되는 전원을 끊어 주므로써 더 이상의 전후진이 이루어지지 않도록 한다.When the cover 16 reaches the rear end or the front end of the transfer rack 14 during the opening and closing operation of the cover 16 as described above, a limit switch (not shown) is contacted to cut off the power applied to the driving motor 18. Do not back and forth above.

이와 같은 본 고안을 적용하면 연주자가 일일이 덮개를 잡아당기거나 밀지않고도 스위치를 누르는 간단한 동작에 의해 덮개를 개폐시킬 수 있음에 따라 그 조작이 편리하다는 효과가 있다.Applying the present invention as described above has the effect that the player can open and close the cover by a simple operation of pressing the switch without pulling or pushing the cover.
