본 고안은 비디오테이프의 유동방지장치에 관한 것으로 특히 카세트하우징에 테이프가 완전히 삽입되지 않으면 하우징구동이 불가능하도록 함과 동시에 테이프안착시 테이프의 흔들림을 방지하도록 한 것이다.The present invention relates to a device for preventing the flow of a video tape, in particular, to prevent the housing from being driven when the tape is not completely inserted into the cassette housing, and to prevent the tape from shaking when the tape is settled.

종래에는 테이프가 완전삽입되어야만 하우징이 동작되도록한 안정장치가 없는 관계로 VTR의 프론트도아에 손을 넣고 카세트하우징을 밀게되면 리프스위치가 접속되어 로오딩 모우터의 구동에 의해 카세트하우징이 동작되는 결함이 있고 또한 테이프가 잘못 삽입될 경우에도 리프스위치가 접속되어 카세트하우징이 동작됨으로써 오삽입된 테이프가 덱크에 안착시 중요포인트가 맞지않아 덱크와 테이프 모두가 손상될 우려가 있으며 테이프 눌림장치의 경우에는 카세트 하우징에 판스프링을 설치하여 테이프 안착시 테이프를 눌러주도록 하였으나, 판스프링이 눌러주는 힘은 형식적인 것에 불과하다.Conventionally, since there is no stabilizer to operate the housing only when the tape is fully inserted, when the user pushes the cassette housing and pushes the cassette housing, the leaf switch is connected and the cassette housing is operated by the driving of the loading motor. In addition, even if the tape is inserted incorrectly, the leaf switch is connected and the cassette housing is operated, so that the important point is not matched when the inserted tape is seated on the deck, and both the deck and the tape may be damaged. The leaf spring is installed in the cassette housing to press the tape when the tape is seated, but the force applied by the leaf spring is only formal.

이는 판스프링 자체의 변형이 심하기 때문에 테이프의 일부분만을 눌러주는 관계로 그 역할이 미흡한 결함이 있었다.Since the leaf spring itself is severely deformed, it only presses a portion of the tape, and thus its role is insufficient.

본 고안은 따라서 위와같은 문제점을 해결하기 위하여 카세트하우징 측면에 테이프 눌림판의 중심을 유동 가능하게 축설하고 누름판의 장공에 스프링의 일단을 고정하여, 비디오 테이프의 삽입여부에 따라서 상기 테이프 눌림판의 경사위치가 변화되어 테이프가 완전 삽입되지 않을 경우에 카세트 하우징이 로오딩 되지 않토록하고 테이프가 덱크에 안착된 상태에서는 테이프눌림판이 테이프를 유동되지 않게 눌러주도록 한것으로 이하 첨부된 도면에 따라 본 고안의 실시예를 상세히 설명하면 다음과 같다.In order to solve the above problems, the present invention provides a fluid housing with a center of the tape pressing plate on the side of the cassette housing, and secures one end of the spring to the hole of the pressing plate, thereby inclining the tape pressing plate according to the insertion of the video tape. The cassette housing is not loaded when the position is changed and the tape is not fully inserted. When the tape is seated on the deck, the tape pressing plate presses the tape not to flow. An example will be described in detail as follows.

즉, 제1도는 본고안의 설치상태를 나타낸 사시도 및 일부결합단면도로서 도시된 바와같이 카세트 하우징(1), 양측면에 한쌍의 테이프 눌림판(2)이 설치되어 있다.That is, FIG. 1 shows a cassette housing 1 and a pair of tape pressing plates 2 on both sides thereof, as shown in a perspective view and a partially engaged cross-sectional view showing the installation state of the present invention.

상기 테이프눌림판(2)은 카세트하우징(1)의 측면 상단에 걸려있고 그 하측으로 스프링(4)이 탄력 설치되며 테이프눌림판(2)의 측면에는 ㅗ자형 유동홈(3)이 형성되고 유동홈의 수직홈부에는 힌지된(4)이 고정된다.The tape pressing plate (2) is hung on the upper side of the cassette housing (1) and the spring (4) is elastically installed on the lower side of the tape pressing plate (2) side of the U-shaped flow groove (3) is formed and flows The hinged 4 is fixed to the vertical groove of the groove.

또한 수평홈부에는 상술한 스프링(4)을 유동가능하게 고정하여 카세트하우징 (2)에 비디오 테이프를 삽입할 경우 테이프눌림판(2)이 좌우로 움직임에 따라서 스프링 (4)의 탄력위치가 변환된다.In addition, when the video tape is inserted into the cassette housing 2 by fixing the spring 4 to the horizontal groove, the elastic position of the spring 4 is changed as the tape pressing plate 2 moves left and right. .

이러한 동작은 테이프눌림판(2)이 하우징내에 위치한 누름부(2a)의 일측 상향절곡턱(2b)과 하향절곡턱(2b)이 테이프의 삽입 유무에 따라 스프링(4)이 눌림판의 유동홈(3)에 형성된 수평홈부에서 어느 일측으로 슬라이드되어 위치하게 됨으로써 카세트하우징(2)의 구동을 방지하거나 비디오테이프를 눌러주는 클램핑 역할을 하게된다.This operation is such that the spring 4 is the flow groove of the pressing plate according to whether the tape pressing plate 2 has one side of the upward bending jaw 2b and the downward bending jaw 2b of the pressing portion 2a positioned in the housing. By being positioned to slide to one side in the horizontal groove formed in (3) to prevent the drive of the cassette housing (2) or to act as a clamping to press the video tape.

제2a, b, c도는 본고안의 작동상태 측면도이다. 먼저 제2a도에서와 같이 테이프 삽입전에는 테이프 눌림판(2)의 상향절곡턱(2b)이 스프링(4)에 의해 톱플레이트(6)의 관통홈(6a)에 걸려 있기 때문에 테이프를 완전히 삽입하기 전까지는 카세트하우징(1)의 구동이 불가능하게 된다.2a, b, and c are side views of the operating state of the present article. First, as shown in FIG. 2A, before the tape is inserted, since the upward bending jaw 2b of the tape pressing plate 2 is caught in the through groove 6a of the top plate 6 by the spring 4, the tape is completely inserted. Until this time, the cassette housing 1 cannot be driven.

이때 테이프눌림판(2)에 형성된 ㅗ자형 유동홈(3)의 수직홈부에 삽입된 힌지핀 (5)을 중심으로 수평홈부에 유동가능하게 고정된 스프링(4)은 낮은쪽으로 쏠려 있게되고 이 스프링(4)의 탄성으로 테이프눌림판(2)의 상향절곡턱(2b)은 톱플레이트(6)에 걸려 결국 카세트하우징(1)의 양측을 잡고 있게 된다.At this time, the spring (4) fixed to the horizontal groove in the horizontal groove centered on the hinge pin (5) inserted into the vertical groove of the U-shaped flow groove (3) formed on the tape pressing plate (2) is pulled to the lower side With the elasticity of (4), the upward bending jaw (2b) of the tape pressing plate (2) is caught by the top plate (6) and eventually hold both sides of the cassette housing (1).

아울러 제2b도와 같이 비디오테이프를 프론트도아(7)를 통해 카세트하우징 (1)에 완전히 밀어 넣으면 비디오테이프의 상면이 카세트하우징(1)의 양측면에 걸쳐있는 테이프눌림판(2)의 누름부(2a)에 접촉함과 동시에 하향절곡턱(2c)을 밀게되고 테이프눌림판(2)은 힌지핀(5)을 중심으로 상향절곡턱(2b)이 하강하면서 톱플레이트(6)의 관통홈(6a)에서 이탈된다.In addition, as shown in FIG. 2B, when the video tape is completely pushed into the cassette housing 1 through the front door 7, the pressing portion 2a of the tape pressing plate 2 having the upper surface of the video tape covering both sides of the cassette housing 1 is shown. ) And the downward bending jaw (2c) is pushed at the same time, the tape pressing plate (2) through the groove 6a of the top plate 6 as the upward bending jaw (2b) descends around the hinge pin (5) Depart from

이와같은 동작중 테이프눌림판(2)의 움직임에 의해 스프링(4)의 위치도 변경되어 시이소 동작하는 테이프눌림판(2)이 비디오테이프를 유동되지 않게 눌러준다. 또한 순간적인 동작으로 카세트테이트가 카세트캐리어 하우징의 톱플레이트(6)에 부착된 리프스위치를 접촉하여 카세트하우징(1)은 수평 및 수직이동하면서 테이프를 덱크에 안착시킨다.During this operation, the position of the spring 4 is also changed by the movement of the tape pressing plate 2 so that the tape pressing plate 2 which is operated by the seesaw presses the video tape not to flow. In a momentary motion, the cassette tape contacts the leaf switch attached to the top plate 6 of the cassette carrier housing so that the cassette housing 1 rests the tape on the deck while moving horizontally and vertically.

제2c도는 덱크의 릴디스크에 테이프가 안착된 상태를 나타낸다. 이때에는 비디오테이프의 허브와 릴디스크의 회전스톱퍼사이에 접촉이 생기므로 테이프를 눌러주는 힘이 커야한다.FIG. 2C shows the tape seated on the reel disk of the deck. At this time, the contact force is generated between the hub of the video tape and the rotation stopper of the reel disk.

그러나 상술한 바와같이 테이프눌림판(2)이 로오딩시 카세트하우징(1)내의 비디오 테이프를 스프링의 탄성으로 눌러 주기때문에 덱크안착시 테이프의 유동을 방지하게되는 것이다.However, as described above, since the tape pressing plate 2 presses the video tape in the cassette housing 1 with elasticity during spring loading, the flow of the tape is prevented when the deck is seated.

한편 테이프가 이젝트되는 과정은 제2c도의 위치에서 제2b도의 위치로 이동되어 비디오 테이프를 손으로 인출한다.Meanwhile, the tape ejecting process is moved from the position of FIG. 2c to the position of FIG. 2b to draw out the video tape by hand.

이때 테이프눌림판(2)의 하향절곡턱(2c)이 비디오테이프의 이탈로 먼저 아래로 내려오면서 테이프눌림판(2)은 시계방향으로 약간 유동함과 동시에 ㅗ자형 유동홈 (3)의 수평홈부의 경사로 인하여 스프링(4)은 낮은쪽으로 미끄러져 위치하게 됨으로써 결국 테이프눌림판(2)의 상향절곡턱(2b)은 자연히 카세트 리세트하우징의 톱플레이트 (6)에 형성된 관통홈(6a)에 삽입되어 카세트하우징(1)을 제2a도와 같이 로크하게되는 것이다.At this time, the downward bending jaw (2c) of the tape pressing plate (2) is first lowered down by the separation of the video tape, the tape pressing plate (2) flows slightly clockwise and at the same time the horizontal groove of the U-shaped flow groove (3) The inclination of the negative causes the spring 4 to slide downward so that the upward bending jaw 2b of the tape pressing plate 2 is naturally inserted into the through groove 6a formed in the top plate 6 of the cassette reset housing. Thus, the cassette housing 1 is locked as shown in FIG. 2A.

이상과같이 본 고안은 테이프가 카세트하우징에 완전히 삽입되지않고 반쯤 삽입되면 하우징동작이 불가능하도록하고 테이프안착시 테이프의 유동을 방지하도록함으로써 VTR의 품질향상은 물론 고장율을 줄일수 있다.As described above, the present invention makes it impossible to operate the housing when the tape is not fully inserted into the cassette housing, and prevents the flow of the tape when the tape is seated, thereby improving the quality of the VTR and reducing the failure rate.

또한 테이프의 오삽입을 억제하여 테이프 손상등을 방지할 수 있는 장점이 있는것이다.In addition, there is an advantage that can prevent the tape damage by inhibiting the wrong insertion of the tape.
