본 고안은 프론트 로오딩방식 브이티알(VTR)에 있어서, 카세트 하우징의 도어 개폐장치에 대한 것이다.The present invention relates to a door opening and closing device of a cassette housing in a front loading VRT.
종래의 카세트 하우징 도어는 그 일측 축에 비틀림 스프링을 결합시켜 이 스프링의 탄발력에 의해 닫혀지도록 하였고 또 도어의 일측면에는 가이드홈을 수직으로 요입 형성하여 개폐핀의 내단을 결합시키고, 이 개폐핀의 외단은 하우징의 일측면판에 원호상으로 길게 뚫은 슬라이드공을 통해 외측으로 노출되게 하여 로오딩 아암에 의해 동작되는 개폐레버의 선단에 착설하여 로오딩 아암이 회동되면 개폐레버가 동작되어 개폐핀을 이동시켜주므로 온도가 열리도록 하였기 때문에 하우징의 좁은 공간에 슬라이드공을 뚫어야 되므로 하우징이 약화되어 충격이 가해지면 도어가 쉬이탈되거나, 또는 하우징과의 연결부분이 파손되는 등의 결점이 있었으며, 부품수가 많고 조립 작업이 어려운 점들도 있었다.Conventional cassette housing door is coupled to the torsion spring on one side of the shaft to be closed by the elastic force of the spring, and on one side of the door to form a guide groove vertically to engage the inner end of the opening and closing pin, this opening and closing pin The outer end of the housing is exposed to the outside through the slide hole, which is circularly drilled on one side plate of the housing, and is installed on the front end of the opening and closing lever operated by the loading arm. When the loading arm is rotated, the opening and closing lever is operated. Since the temperature is opened because it moves the slide hole, the slide hole must be drilled in the narrow space of the housing, so when the housing is weakened and the impact is applied, the door may be detached or the connection part with the housing may be broken. There were a lot of things and the assembly work was difficult.
본 고안은 이러한 점들을 감안하여 고안한 것으로서 도어의 일측축이 하우징을 관통, 외측으로 노출되게하여 이에 피니언을 축착하고 로오딩 아암에 의해 동작되는 개폐레버의 선단부에는 래크를 형성하여 상기 피니언과 맞물리도록 결합시켜 래크와 피니언의 연동작용에 의해 도어가 개폐되게 하므로 그 구조가 간단하고 개폐동작이 확실하게 이루어 지도록 한 것이다.The present invention has been devised in view of these points, and one side shaft of the door penetrates the housing and is exposed to the outside, thereby pinning the pinion and forming a rack at the tip of the opening / closing lever operated by the loading arm to engage the pinion. The door is opened and closed by interlocking action of the rack and pinion, so that the structure is simple and the opening and closing operation is made sure.
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.
본 고안은 제 1 도 및 제 2 도에서 보는 바와 같이 도어(3)의 일측 축(4)은 하우징(1)에 뚫은 관통공(2)을 통해 외측으로 노출되게 결합하여 피니언(5)을 축착하고, 개폐레버(6)는 양측에 장공(7)(7')을 뚫어 하우징(1)에 형성하고 착설한 가이드편(8)및 가이드핀(9)을 각각 끼워 이들에 의해 개폐레버(6)는 수평 상태로 전후 이동될 수 있게 하며 선단부 상면에는 래크(10)를 형성하여 상기 피니언과 맞물리게 하고 걸이턱(11)과 하우징(1)의 걸이턱(11')사이에는 인장스프링(12)을 걸어주어 그 수축력에 의해 개폐레버(6)가 항상 전방으로 당겨지도록 하며, 이 레버의 후단부(6')는 하향 경사지게 연설하고 이에 받침편(13)을 일체로 길게 돌출하여서 된 것이다.According to the present invention, as shown in FIGS. 1 and 2, the one side shaft 4 of the door 3 is coupled to be exposed to the outside through the through hole 2 drilled in the housing 1, thereby pinching the pinion 5. In addition, the opening and closing lever 6 is formed in the housing 1 by drilling the long holes 7 and 7 'on both sides, and the guide pieces 8 and the guide pins 9, which are installed and fitted, respectively, are inserted and closed by the opening and closing levers 6 ) Can be moved back and forth in a horizontal state, and the rack 10 is formed on the top surface of the front end to engage the pinion and the tension spring 12 between the hooking jaw 11 and the hooking jaw 11 'of the housing 1. The opening and closing lever 6 is always pulled forward by the contracting force, and the rear end 6 'of the lever is inclined downward and protrudes the supporting piece 13 integrally therefrom.
미설명 부호 "14"는 로오딩 기어이고, "15"는 로오딩 아암이며, "16"은 로오딩 공이고, "17"은 카세트 플레이트의 측면에 착설된 스터드이다.Reference numeral "14" is a loading gear, "15" is a loading arm, "16" is a loading ball, and "17" is a stud mounted on the side of the cassette plate.
이와같이 구성된 본 고안의 동작상태를 설명하면 다음과 같다.Referring to the operating state of the present invention configured as described above are as follows.
제 2 도는 카세트가 삽입되지 않은 상태의 측면도로서 도어(3)은 닫혀있고 개폐레버(6)는 인장스프링(12)의 수축력에 의해 전진되어 있으며, 로오딩 아암(15)의 상단부 가이드공에 끼워져 있는 스터드(17)는 로오딩공(16)의 상부 선단에 위치하고 있게 되고, 또 이때 로오딩 아암(15)의 상단부는 개폐레버(6)와 닿지 않게 그 외측에 격리된 상태로 있게 된다.2 is a side view of the cassette not inserted, the door 3 is closed and the opening and closing lever 6 is advanced by the retraction force of the tension spring 12, and is inserted into the guide hole at the upper end of the loading arm 15. The stud 17 is located at the upper end of the loading hole 16, and at this time, the upper end of the loading arm 15 is insulated on the outside so as not to contact the open / close lever 6.
이러한 상태에서 카세트를 삽입하면 도어(3)가 내측으로 열리게 되므로 피니언(5)이 회전되고 이에 따라 그 회전력이 래크(10)를 통해 개폐레버(6)에 전달되어 이 레버를 후진시켜 주며 동시에 인장스프링(12)은 늘어나게 된다.When the cassette is inserted in this state, the door 3 is opened inward, so the pinion 5 is rotated, and thus the rotational force is transmitted to the open / close lever 6 through the rack 10 to reverse the lever and at the same time tension The spring 12 is stretched.
한편, 삽입된 카세트에 의해 하우징(1)의 상면에 설치된 통상의 감지스위치가 동작되어 로오딩 모우터를 구동시켜 주므로 로오딩 기어(14)가 회전되어 로오딩 아암(15)이 회전되며 이에 따라 스터드(17)가 로오딩공(16)내에서 이동하게 되어 카세트 플레이트를 이동시켜 주게 되므로 삽입된 카세트의 안착동작이 진행되는데, 이때 제 3a 도에서 보는 바와같이 회전되는 로오딩 아암(15)의 상단부가 개폐레버(6)의 후단부(6')측에 도달하면 이 부분에 돌출된 받침편(13)과 접촉되어 밀어주게 되므로 이후 부터는 로오딩 아암(15)에 의해 개폐러버(6)가 후진하게 되므로 도어(3)는 열림상태를 그래도 유지하게 되며 제 3b 도에서와 같이 로오딩 아암(15)의 상단부가 상기 개폐레버의 후단부(6')에서 경사진 하단에 도달하게 되면 도어(3)는 열림상태를 그대로 유지하게 되며 제 3b 도에서와 같이 로오딩 아암(15)의 상단부가 상기 개폐레버의 후단부(6')에서 경사진 하단에 도달하게 되면 더 이상 개폐레버(6)를 밀어주지 못하게 된다.On the other hand, since the normal sensing switch installed on the upper surface of the housing 1 is operated by the inserted cassette to drive the loading motor, the loading gear 14 is rotated so that the loading arm 15 is rotated. Since the stud 17 is moved in the loading hole 16 to move the cassette plate, the seating operation of the inserted cassette proceeds. At this time, as shown in FIG. 3a, the upper end of the loading arm 15 is rotated. Reaches the rear end 6 'side of the open / close lever 6, and the support piece 13 protrudes in this part so as to be pushed. Therefore, the open / close rubber 6 is retracted by the loading arm 15 thereafter. Since the door 3 remains open, the door 3 is opened when the upper end of the loading arm 15 reaches the lower end inclined at the rear end 6 'of the opening / closing lever as shown in FIG. ) Will remain open. When the upper end of the Lawrence ding arm 15, as shown in Figure 3b to reach the bottom of the inclined at the ends (6 ') after the opening lever is not able any more to push the opening and closing lever (6).
이렇게 되면 늘어났던 인장스프링(12)의 수축력에 의해 개폐레버(6)는 전진되며 이에 따라 래크(10)와 피니언(5)의 연동작동으로 도어(3)는 닫히게 되고 상기개폐레버의 후단부(6')에 돌출된 받침편(13)은 로오딩 아암(15)의 상단에 받쳐지게 되며 이때 스터드(17)는 로오딩공(16)의 하단에 위치하게 되고 카세트는 데크에 안착되는 것이다.In this case, the opening and closing lever 6 is advanced by the contracting force of the tension spring 12 which is increased, and thus the door 3 is closed by the interlocking operation of the rack 10 and the pinion 5 and the rear end 6 of the opening and closing lever 6. The support piece 13 protruding into ') is supported at the upper end of the loading arm 15, wherein the stud 17 is positioned at the lower end of the loading hole 16 and the cassette is seated on the deck.
이러한 상태에서 카세트를 추출하게 되면 로오딩기어(14)가 역회전 하므로 로오딩 아암(15)도 역회전 되며 이에 따라 그 상단부가 개폐레버(6)의 후단부(6')에 돌출된 받침편(13)을 자나 가면서 상기 개폐레버(6)를 후진 시켜주게 되므로 제 3a 도와 같은 상태를 거치게 되어 도어(3)가 열리게되며 이후 카세트를 완전히 꺼내주면 모든 상태는 제 2 도에서 보는 바와 같이 원상태로 되돌아가게 되는 것이다.When the cassette is extracted in such a state, since the lowering gear 14 rotates in reverse, the lowering arm 15 also rotates in reverse, so that the upper end protrudes from the rear end 6 'of the opening / closing lever 6. The opening and closing lever 6 is reversed while going out of (13), so that the door 3 is opened by going through the same state as in FIG. 3a, and when the cassette is completely removed, all states are returned to the original state as shown in FIG. It is going back.
이와같은 작동되는 본 고안은 도어의 개페동작이 래크와 피니언에 의해 이루어 지도록 하였기 때문에 그 동작이 항상 확실하고도 원활하게 되며, 또 하우징에는 도어축의 축공만 뚫어 주면되므로 하우징의 강도를 약화시켜주지 않게 됨은 물론 전체적인 구조가 간단하고 부품조립이 편리하게 되는등 매우 효과적인 고안이다.The present invention, which is operated as described above, is designed to open and close the door by the rack and pinion, so that the operation is always sure and smooth, and only the shaft hole of the door shaft is drilled in the housing, so as not to weaken the strength of the housing. Of course, the overall structure is simple and the parts are easy to assemble.
