본 고안은 비디오 테이프 레코오더 또는 오디오 테이프 레코오더등의 테이프 레코오더에 있어서, 릴의 회전을 정지시키는 소프트 릴 브레이크 장치에 관한 것으로, 특히 릴의 저면과 외주면에는 마그네트 및 철편을 각기 설치하고, 마그네트의 하부에는 코일을 설치하며 릴의 외주면과 일정간격을 유지하면서 마찰편을 갖는 전자석을 설치하여 코일에 유기된 마그네트의 자계 변화로 릴의 회전 토오크를 조절할 수 있게 한 테이프 레코오더의 소프트 릴 브레이크 장치에 관한 것이다.The present invention relates to a soft reel brake device that stops the reel rotation in a tape recorder such as a video tape recorder or an audio tape recorder. In particular, a magnet and a piece of iron are provided on the bottom and the outer circumferential surface of the reel, respectively Soft reel brake device of tape recorder that installs coil in the lower part and adjusts reel's rotational torque by changing magnet's magnetic field induced in coil by installing electromagnet with friction piece while keeping constant distance from outer peripheral surface of reel It is about.
종래의 테이프 레코오더에 사용된 소프트 릴 브레이크 장치는 그 동작이 원활하지 못하고, 또한 그 구성이 매우 복잡함은 물론 릴의 회전 토오크를 조절 할 수 없는 결함이 있었다.The soft reel brake device used in the conventional tape recorder is not smooth in operation, and the configuration thereof is very complicated and also has a defect that the rotational torque of the reel cannot be adjusted.
본 고안은 이와 같은 종래의 결함을 감안하여, 릴의 회전 토오크를 조절할 수 있는 간단한 구성의 소프트 릴 브레이크 장치를 안출한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional defects, a soft reel brake device having a simple configuration that can adjust the rotational torque of the reel, it will be described in detail by the accompanying drawings as follows.
제1도에 도시한 바와 같이 회전축(1)에 축설된 릴(2)의 외주면에 보자력이 매우 작은 재질의 철편(3)를 설치하고, 릴(2)의 저면에는 제2도에 도시한 바와 같이 N 및 S극이 일정 간격으로 수개가 설치된 마그네트(4)를 설치하며, 마그네트(4)하부의 베이스(5)상에는 상기 마그네트(4)의 자계 변화를 검출하는 수개의 코일(7)이 고정된 기판(6)을 설치하는 한편, 릴(2)의 외축 기판(6)상에는 수개의 고정보울트(8)로 ""형 단면의 호울더(9)를 고정하고, 그 호울더(9)에는 내외측으로 이동가능하게 ""형 단면의 미끄럼호울더(10)를 수개 설치하고, 그 호울더(10)에는 제3도에 도시한 바와 같이 전자석(11) 및 철편(12)을 각기 누착하고, 그 전자석(11)의 사이에는 스프링(13)을 각기 설치하여 구성한 것이다.As shown in FIG. 1, an iron piece 3 of a material having a very small coercive force is provided on the outer circumferential surface of the reel 2 built on the rotating shaft 1, and the bottom of the reel 2 is shown in FIG. Likewise, N and S poles are provided with several magnets 4 provided at regular intervals, and several coils 7 for detecting magnetic field changes of the magnets 4 are fixed on the base 5 under the magnets 4. On the outer shaft substrate 6 of the reel 2, a plurality of high information bolts 8 are provided. "Hold the holder 9 of the cross section, and the holder 9 is movable inside and outside." "Slip holder 10 of a cross section is provided several times, and the electromagnet 11 and the iron piece 12 are respectively stuck to the holder 10, as shown in FIG. The springs 13 are installed in between.
한편, 제4도는 본 고안 브레이크 장치의 상세 회로도로서, 이에 도시한 바와 같이 코일(7)을 다이오드(14)를 통해 콘덴서(15)에 접속함과 아울러 그 접속점을 스위치(16)를 통해 전자석(11)에 접속하여 구성한 것이다.On the other hand, Figure 4 is a detailed circuit diagram of the brake device of the present invention, as shown in this connection, the coil 7 is connected to the capacitor 15 through the diode 14 and the connection point is connected to the electromagnet ( And 11).
이와 같이 구성된 본 고안의 작용효과를 상세히 설명하면 다음과 같다.Referring to the effect of the present invention configured in this way in detail as follows.
릴(2)의 회전에 따라 그의 저면에 설치된 마그네트(4)가 회전되면, 마그네트(4)의 회전에 따라 코일(7)에 유기되는 자계가 변화되어 일정전압을 검출하고, 그 검출된 전압은 다이오드(14)를 통해 정류되며, 그 정류된 전압은 콘덴서(15)에 의해 평활된 후 스위치(16)를 통해 전자석(11)에 인가되므로, 전자석(11)은 일정자계를 갖게되고, 이에 따라, 전자석(11)이 릴(2)의 외주면에 부착된 철편(3)에 접촉하려는 성질에 의해 미끄럼하우징(10)이 내측으로 약간 이동하므로 마찰편(12)이 철편(3)에 접촉되어 릴(2)의 회전 토오크를 저지한다.When the magnet 4 installed on the bottom of the reel 2 is rotated as the reel 2 rotates, the magnetic field induced in the coil 7 changes as the magnet 4 rotates to detect a constant voltage, and the detected voltage is The rectified voltage is rectified through the diode 14, and the rectified voltage is smoothed by the capacitor 15 and then applied to the electromagnet 11 through the switch 16, so that the electromagnet 11 has a constant magnetic field. Since the sliding housing 10 slightly moves inward due to the property of the electromagnet 11 to contact the iron piece 3 attached to the outer circumferential surface of the reel 2, the friction piece 12 is in contact with the iron piece 3 to reel. The rotational torque of (2) is prevented.
그리고, 릴(2)의 회전이 매우 빠르면, 코일(7)에 의해 검출되는 전압이 높아 전자석(11)에 인가되는 전압이 높게되므로, 마찰편(12)의 철편(3)에 보다 밀착되어 릴(2)의 회전토오크를 매우 강하게 저지한다.When the reel 2 is rotated very fast, the voltage detected by the coil 7 is high and the voltage applied to the electromagnet 11 is high, so that the reel 2 is closer to the iron piece 3 of the friction piece 12. The torque in (2) is very strong.
즉, 릴(2)의 회전이 느리면 그 회전 토오크를 약하게 저지하고, 회전이 빠를수록 회전토오크를 점점 강하게 저지하게 된다.That is, the slower the rotation of the reel 2, the weaker the rotational torque, and the faster the rotational rotational torque is increasingly stronger.
그리고, 사용자가 테이프 레코오더를 조작하여 스위치(16)를 개방시키면, 전자석(11)에 인가된 전압이 차단되므로 전자석(11)은 스프링(13)의 탄성력에 의해 원상복귀되면서 미끄럼 하우징(10)이 원상복귀되고, 이에 따라 마찰편(12)이 철편(3)에 접촉되지 않아 릴(2)은 자유롭게 회전한다.Then, when the user operates the tape recorder to open the switch 16, the voltage applied to the electromagnet 11 is cut off so that the electromagnet 11 is returned to its original state by the elastic force of the spring 13 and the sliding housing 10 This recirculation returns, and the friction piece 12 does not contact the iron piece 3, and the reel 2 rotates freely.
이상에서 설명한 바와 같이 본 고안은 마그네트의 자계를 검출하여 릴의 회전토오크를 조작하는 것으로, 그 구성이 간단함은 물론 동작이 원활하여 테이프 레코오더의 신뢰성을 높이는 효과가 있다.As described above, the present invention detects the magnetic field of the magnet and operates the revolving torque of the reel. The configuration is simple and the operation is smooth, thereby increasing the reliability of the tape recorder.
