본 고안은 브이티알(VTR)이나 오디오등과 같은 전기, 전자제품의 콘트롤부 도어 자동 열림 장치에 대한 것이다.The present invention relates to a control door automatic opening device for electrical and electronic products such as VTR or audio.

종래에는 콘트롤부의 도어를 일일이 손으로 열어주어야 되었기 때문에 사용이 매우 불편하고 번거로웠으며, 특히 브이티알등과 같은 고가의 제품인 경우 그 제품 가치를 저하시키는 요인이 되었다.In the related art, since the door of the control unit had to be opened by hand, it was very inconvenient and hassle-free, and in the case of an expensive product such as VTI, it was a factor that lowers the value of the product.

본 고안은 이러한 점들을 감안하여 고안한 것으로 도어의 내면 일측에는 영구자석을, 이에 대응하는 위치의 콘트롤부 내면판에는 전원이 통전되면 극성이 상기 영구자석과 반대로 되도록 전자석을 각기 착설하여 브이티알의 경우 카세트 테이프를 하우징에 삽입하며, 하우징에 부설된 카세트 인식 스위치가 이를 감지하여 하우징을 동작시켜 줄 때 전자석에도 전원을 통전시켜 주도록 하므로 영구자석의 극성과 전자석의 극성이 반대가 되어 반발 자력에 의해 도어가 자동으로 열리도록 한 것이다.The present invention has been devised in consideration of these points, and the permanent magnet is installed on one side of the door, and the electromagnet is installed so that the polarity is opposite to the permanent magnet when the power is supplied to the control panel of the corresponding position. In this case, the cassette tape is inserted into the housing, and the cassette recognition switch attached to the housing detects this and supplies power to the electromagnet when the housing is operated so that the polarity of the permanent magnet and the electromagnet are reversed. The door opens automatically.

이하 본 고안의 실시예를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제품의 전면판(1)에 설치하는 콘트롤부(2)에 도어(3)를 축착함에 있어, 이 도어의 내면 상부 적정 위치에는 영구자석(4)을 고정 부착하고, 이에 대응하는 위치의 콘트롤부(2) 내면판(5)에는 전원이 통전되면 극성이 상기 영구자석과 반대로 되도록 전자석(6)을 착설하여서 된 것이다.In condensing the door 3 to the control unit 2 installed on the front plate 1 of the product, the permanent magnet 4 is fixedly attached to an appropriate position on the inner surface of the door, and the control unit at the corresponding position (2) In the inner plate 5, the electromagnet 6 is installed so that the polarity thereof is opposite to the permanent magnet when the power is energized.

미설명부호 "7"은 브이티알의 전원부이고, "8"은 콘트롤 스위치이며, "SW1"은 브이티알의 경우 카세트 하우징에 부설되는 카세트 인식 스위치이다.Reference numeral “7” denotes a power supply unit of VTIAL, “8” denotes a control switch, and “SW1” denotes a cassette recognition switch attached to the cassette housing in the case of VTIAL.

이와같이 구성된 본 고안은 전자석(6)에 전원이 통전되지 않을 때에는 도어(3)를 닫으면 영구자석(4)이 그 자력에 의해 전자석(6)의 철심에 부착되므로, 도어(3)가 닫힌 상태에서 임의로 열리지 않게 되는 것으로 통상의 카세트 하우징에 카세트 테이프를 삽입하면 카세트 인식 스위치(SW1)가 동작하여 하우징 구동 모우터에 통전을 시켜주게 됨과 동시에 전자석(6)에도 통전을 시켜 주게 되며 , 이렇게 되면 전자석(6) 영구자석(4)과 반대의 극성이 되므로 이들 자석의 반발 자력에 의해 서로 밀어지게 되기 때문에 도어(3)가 열리게 되는 것이다.The present invention constructed as described above has the permanent magnet 4 attached to the iron core of the electromagnet 6 by its magnetic force when the door 3 is closed when the electromagnet 6 is not energized, so that the door 3 is closed. When the cassette tape is inserted into the conventional cassette housing, the cassette recognition switch SW1 operates to energize the housing driving motor and energize the electromagnet 6 at this time. 6) Since the polarity opposite to the permanent magnet 4 is pushed together by the repulsive magnetic force of these magnets, the door 3 is opened.

이와같은 과정에서 카세트 인식 스위치(SW1)는 통상 하우징의 구동 모우터가 구동을 시작 하도록 하여 주는 극히 짧은 시간만 동작하므로 전자석(6)도 이 시간 동안만 작동하게 되기 때문에 일단 도어(3)가 열리면 전자석(6)은 작동되지 않게 되어 콘트롤 스위치(8)를 조작한 다음, 또는 조작하지 않고 도어(3)를 그대로 닫아 주면 다시 영구자석(4)이 전자석(6)의 철심에 부착되므로 닫힌 상태에서 로크되는 것이다.In this process, since the cassette recognition switch SW1 normally operates for a very short time to allow the drive motor of the housing to start driving, the electromagnet 6 also operates only during this time, so that once the door 3 is opened, When the electromagnet 6 is not operated and the control switch 8 is operated, or the door 3 is closed without it, the permanent magnet 4 is attached to the iron core of the electromagnet 6, so that the electromagnet 6 is closed. It is locked.

이와같이 작동되는 본 고안은 카세트 테이프를 하우징에 삽입시켜 카세트 인식 스위치가 동작되면 전자석에 전원이 통절되어 영구자석과 극성이 반대가 되므로 도어가 자동으로 열리도록 하였기 때문에 콘트롤부의 각 콘트롤 스위치 사용이 매우 편리하게 되며, 이에따라 고가의 제품에 매우 적합한 고안인 것이다.The present invention, which operates as described above, inserts a cassette tape into the housing, and when the cassette recognition switch is operated, the power is supplied to the electromagnet and the polarity of the permanent magnet is reversed, so that the door opens automatically. Therefore, the design is very suitable for expensive products.
