본 고안은 VCR의 카세트 커어버 해제장치에 관한 것으로, 특히 프론트 로딩형 VCR에 있어서 카세트-인 스위치(cassette-in switch)가 겸비된 카세트 커어버의 해제장치에 관한 것이다.The present invention relates to a cassette cover release device of a VCR, and more particularly, to a cassette cover release device having a cassette-in switch in a front loading type VCR.

일반적으로 프론트 로딩형 VCR에 있어서는 프론트 로딩 하우징의 상부 플레이트에 카세트인 스위치가 구비되어 있으며, 제1도에서 보인 바와같이 카세트홀더(1)의 측벽(2)에는 해제돌핀(3)을 갖는 해제스프링(4)이 착설되어 카세트가 삽입되었을 때에 카세트의 전면커어버를 고정하고 있는 고정핀을 눌러주어 전면커어버가 해제된 후 카세트의 로딩시에 개방될 수 있도록 되어 있다.In general, in the front loading type VCR, a switch which is a cassette is provided on the upper plate of the front loading housing, and as shown in FIG. 1, a release spring having a release dolphin 3 is formed on the side wall 2 of the cassette holder 1. (4) is installed so that when the cassette is inserted, the fixing pin holding the front cover of the cassette is pushed down so that the front cover is released and can be opened upon loading the cassette.

그러나 종래의 이와같은 구조로 프론트 로딩 하우징의 상부 플레이트상에 텔레비젼 세트등과 같은 무거운 물건을 올려 놓았을 때에 카세트-인 스위치가 오작동하여 카세트가 완전삽입전에 내부로 조기로딩되므로서 중간에 걸리게 되는 등 여러가지 문제점이 있었다.However, in the conventional structure, when a heavy object such as a TV set is placed on the upper plate of the front loading housing, the cassette-in switch malfunctions and the cassette is prematurely loaded into the interior before being fully inserted. There were various problems.

본 고안에 있어서는 종래의 이와같은 점을 감안하여 카세트-인 스위치를 카세트 커어버 해제장치에 겸비되도록 구성하므로서 카세트 커어버의 해제와 동시에 카세트가 카세트홀더에 정확히 삽입된 상태가 카세트-인 스위치에 의하여 감지되고 이 카세트-인 스위치에 의하여 감지되고 이 카세트-인 스위치의 작동으로 카세트의 안정된 로딩이 이루어질 수 있도록 한 것인 바, 이를 첨부도면에 의거하여 보다 상세히 설명하면 다음과 같다.In the present invention, the cassette-in switch is configured to have a cassette cover release device in view of such a conventional situation, and the cassette is inserted into the cassette holder at the same time as the cassette cover is released. It is sensed and sensed by this cassette-in switch to enable a stable loading of the cassette by the operation of the cassette-in switch, which will be described in more detail based on the accompanying drawings.

제2도 및 제3도에 도시한 바와같이, 커어버(10)가 고정핀(11)으로 로크되어진 카세트(12)를 카세트홀더(13)에 삽입하고, 이 카세트홀더(13)에 의하여 카세트(12)가 로딩되도록 한 것에 있어서, 카세트홀더(13)의 측벽(14)에 외측으로 접점고정대(15)를 착설하여 이에 평행한 3개의 접점편(16) (17) (18)을 착설하고, 측벽(14)의 내측으로는 카세트(12)의 커어버(10)가 로딩중에 열릴 수 있도록 고정핀(11)을 눌러주는 돌출부(19)가 중간부에 형성되고 경사면(20)이 전방부에 형성된 고정핀해제스프링(23)의 후방단부(24)를 고정하며, 그 해제스프링(23)의 전방단부(21)에는 내측접점편(16)이 삽입연결되는 분할핀(22)을 고정하여서된 것으로, 상기 접점편(16) (17) (18)은 카세트-인 스위치로 작용하는 것이며, 접점편(16) (17) (18)이 서로 분리되어 있거나, 함께 접속되면 카세트-인 스위치가 오프되고, 접점편(16) (17)이 접속되면 카세트-인 스위치가 온되면서 소정시간후에 카세트 프론트 로딩모터가 회전하여 그 구동력으로 프론트 로딩장치가 구동되도록 전기적 회로가 구성된다.As shown in FIG. 2 and FIG. 3, the cassette 12 in which the cover 10 is locked by the fixing pin 11 is inserted into the cassette holder 13, and the cassette holder 13 causes the cassette. (12) is loaded, and the contact fixing stand (15) is installed on the side wall (14) of the cassette holder (13) outward and three contact pieces (16) (17) (18) parallel to it are installed. On the inner side of the side wall 14, a protrusion 19 for pressing the fixing pin 11 is formed in the middle portion so that the cover 10 of the cassette 12 can be opened during loading, and the inclined surface 20 is the front portion. Fixing the rear end portion 24 of the fixing pin release spring 23 formed in the, and to the front end portion 21 of the release spring 23 by fixing the split pin 22 is inserted into the inner contact piece 16 The contact pieces 16, 17 and 18 serve as cassette-in switches, and the contact pieces 16, 17 and 18 are separated from each other or connected together. When the contact pieces 16 and 17 are connected to each other, the cassette-in switch is turned on and the cassette front loading motor is rotated after a predetermined time so that the front loading device is driven by the driving force.

그리고 도면에서 미설명 부호 25는 카세트홀더(13)에 형성된 스토퍼를 보인 것이다.In addition, reference numeral 25 in the drawing shows a stopper formed in the cassette holder 13.

이와같이된 본 고안은 카세트홀더(13)에 카세트(12)를 삽입하여 밀어넣으면 그 카세트(12)가 고정핀해제스프링판(23)의 경사면(20)에 접촉되면서 해제스프링판(23)을 외측으로 이동시키며 밀어넣어 해제스프링판(23)의 돌출부(19)가 카세트(12)에 접촉되면 해제스프링판(23)이 외측으로 더 이동하여 그 해제스프링판(23)의 전방단부(21)에 연결된 분할핀(22)에 의하여 내측접점편(16)이 외측으로 밀리면서 접점편(16) (17) (18)이 동시에 접속되어 카세트-인 스위치가 오프되고 프론트 로딩 모터는 회전하지 않는다.When the cassette 12 is inserted into and pushed into the cassette holder 13, the present invention as described above contacts the inclined surface 20 of the fixing pin release spring plate 23 with the release spring plate 23 outside. When the projection 19 of the release spring plate 23 comes into contact with the cassette 12, the release spring plate 23 further moves outward to the front end 21 of the release spring plate 23. As the inner contact piece 16 is pushed outward by the connected split pin 22, the contact pieces 16, 17 and 18 are simultaneously connected so that the cassette-in switch is turned off and the front loading motor does not rotate.

카세트(12)를 계속 밀어넣어 카세트 커어버(10)가 카세트홀더(13)의 스토퍼(25)에 밀착된 상태로 카세트홀더(13)에 안착되면 고정핀해제스프링판(23)의 돌출부(19)가 카세트(12)의 커어버(10)가 열리지 않도록 로크하고 있는 고정핀(11)을 눌러 카세트(12)속으로 들어가게 하여 커어버(10)가 열릴 수 있도록 로크상태를 해제하는 동시에 고정핀해제스프링판(23)이 탄성에 의하여 어느정도 복원되면서(원래위치까지는 되돌아가지 못함), 접점편(16) (17)이 접속되어 카세트-인스위치가 온되고 이에따라 프론트 로딩 모터가 회전하여 그 모터의 구동력에 의해 카세트(12)가 자동으로 로딩된다.When the cassette 12 is continuously pushed in and the cassette cover 10 is seated on the cassette holder 13 while being in close contact with the stopper 25 of the cassette holder 13, the protrusion 19 of the fixing pin release spring plate 23 is fixed. Press the locking pin 11 which is locked so that the cover 10 of the cassette 12 does not open, and enters into the cassette 12 to release the lock state so that the cover 10 can be opened. As the release spring plate 23 is restored to some extent by elasticity (it cannot be returned to its original position), the contact pieces 16 and 17 are connected so that the cassette-in switch is turned on and the front loading motor rotates accordingly. The cassette 12 is automatically loaded by the driving force.

상기한 바와 같은 과정에서 카세트(12)가 카세트홀더(13)에 삽입되는 때에 카세트(12)가 해제스프링판(23)의 경사면(20)을 타고 들어가면 분할편(22)이 접점편(16) (17)을 순간적으로 접속시켜 카세트-인 스위치가 온되어지거나 카세트-인 스위치는 온되고도 소정시간이 지난후에야 동작되므로 즉 지연시간(delay time)이 있도록 회로구성이 되어 있으므로 그때에 로딩모터가 구동될 염려는 없다.When the cassette 12 is inserted into the cassette holder 13 in the above-described process, when the cassette 12 enters the inclined surface 20 of the release spring 23, the split piece 22 is connected to the contact piece 16. (17) is instantaneously connected so that the cassette-in switch is turned on or the cassette-in switch is operated only after a predetermined time has elapsed. That is, the circuit is configured so that there is a delay time. There is no need to run it.

상기와 같이된 본 고안은 카세트-인 스위치를 카세트 커어버의 해제장치에 유기적으로 결합시켜 작동되게 함으로써 카세트 하우징의 상부 플레이트를 간단한 구조로 구성할 수 있고, 사용 부품수를 줄이어 원가를 절감할 수 있으며, 조립시간을 단축할 수 있는 이점이 있다.The present invention as described above can be configured to operate by combining the cassette-in switch to the release device of the cassette cover, the upper plate of the cassette housing can be configured in a simple structure, reducing the number of parts used to reduce the cost And, there is an advantage that can shorten the assembly time.
