* 도면의 주요부분에 대한 부호의 설명* Explanation of symbols for main parts of the drawings

1 : 하프다운 2 : 릴삽입공1: half down 2: reel insertion hole

3 : 하프엎 5, 5' : 릴3: half-tuck 5, 5 ': reel

8 : 통풍구8: vent

본 고안은 비디오 테이프 카세트에 관한 것으로서, 하프다운(Half Down)의 릴 삽입공을 동심원으로 한 다수의 통풍구를 천공하여 릴이 회전할때 공기 저항을 감소시켜 주행성을 높인 것이다.The present invention relates to a video tape cassette, which drills a plurality of vent holes having a concentric circle with a reel insertion hole of a half down, thereby improving driving performance by reducing air resistance when the reel rotates.

종래의 비디오 테이프 카세트는 밀폐 형의 구조에서 테이프가 VTR에 안될때 특히, 빨리 감기 또는 빨리 되감기 모드에서 고속으로 회전하는 릴과 밀폐된 카세트 내부의 공기와 마찰되어 릴의 회전 즉, 주행에 방해를 줌으로서 효율이 낮은 결점이 있었다.Conventional video tape cassettes in a closed-type structure, especially when the tape is not in the VTR, friction with the reel rotating at high speed in the fast-forward or fast-rewind mode and the air inside the sealed cassette to prevent the reel rotation, i.e. driving. There was a drawback of low efficiency as zoom.

또한, VTR 덱크상에 설치된 이슬 맺힘방치장치나, 모우터등에서 발생되는 열에 의해 테이프에 전달된 열이 카세트에 감긴 테이프에 의해 밀폐된 카세트 내부에 지속적으로 잔류하여 카세트의 변형을 유지할 수 있고, 무엇보다도 테이프의 기록면에 치명적인 손상을 입히게 되어 실험상의 재생 횟수보다 적은 사용에도 면의 질이 현저하게 저하되는 결점이 있었던 것이다.In addition, the heat transferred to the tape by the dew binding device installed on the VTR deck, the heat generated from the motor, etc. can remain in the cassette sealed by the tape wound on the cassette to maintain the deformation of the cassette. In addition, the recording surface of the tape would be fatally damaged, and the quality of the surface would be remarkably deteriorated even if the number of times of reproduction was experimentally reduced.

본 고안은 위에서 설명한 바와 같은 종래의 문제점을 해결하기 위하여 통상적인 비디오 테이프 카세트의 하프다운에 릴 삽입공을 동심원으로 하는 통풍구를 천공하여 릴의 주행시 발생되는 공기 와류 현상을 방지하고 카세트 내부로 유입된 열기를 발산시키도록 하여 릴의 주행성을 향상시킨 비디오 카세트를 제공 하려는 것이다.In order to solve the above-mentioned problems, the present invention penetrates a vent hole having a reel insertion hole in the half-down of a conventional video tape cassette to prevent the air vortex generated when the reel is driven and flows into the cassette. The aim is to provide a video cassette that allows the heat to dissipate and improves the reel's operability.

이를 첨부 도면에 의거 상세하게 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.

하프다운(1)의 릴 삽입공(2)고 하프업(3)의 지지스프링(4)과 중심이 일치하는 위치에 릴(5)을 안착시키고 전면에 카세트커버(6)를 착설하여서 된 통상적인 비디오 테이프 카세트(7)에 있어서, 하프다운(1)의 릴삽입공(2)을 동심원으로 하는 다수의 통풍구(8)를 천공한 구조이며, 미설명부호(9)은 덱크(Dec)이다.A reel 5 is mounted at a position where the reel insertion hole 2 of the half down 1 and the support spring 4 of the half up 3 are centered, and a cassette cover 6 is installed on the front side. The in-video tape cassette 7 has a structure in which a plurality of ventilation holes 8 having concentric circles of the reel insertion hole 2 of the half-down 1 are drilled, and the reference numeral 9 is a deck. .

이와같이 구성된 본 고안은 첨부도면 제2도와 같이 VTR에 로딩되어 덱크(9)에 안착된 상태의 비디오 테이프 카세트(7)를 표현하고 있다.The present invention configured as described above represents the video tape cassette 7 loaded on the VTR and seated on the deck 9 as shown in FIG.

이와같은 상태는 카세트 커버(6)가 열려지고 테이프는 인출되어 헤드에 접촉되어지면서, 캡스턴 롤러의 회전에 의해 릴(5)에 감겨있는 테이프가 풀리거나 우측 릴(5')에 감기게 된다.In this state, the cassette cover 6 is opened and the tape is drawn out to contact the head, and the tape wound on the reel 5 is released or wound on the right reel 5 'by the rotation of the capstan roller.

이렇게 작동되는 동안 덱크(9)상의 여러 회전부품 등에서 발생된 열이 비디오 테이프 카세트(7)를 가열하게 된다. 그리고, 테이프가 헤드를 거쳐 카세트 내부로 감기는 동안 열을 받아서 그 잔열을 갖고 카세트(7)내부로 감겨서 열을 유입하게 된다.During this operation, heat generated from various rotating parts and the like on the deck 9 heats the video tape cassette 7. Then, the tape receives heat while the tape is wound into the cassette and passes through the head to the inside of the cassette 7 with the residual heat, thereby introducing heat.

그러나, 카세트(7)내부로 유입된 열기는 하프다운(1)의 릴삽입공(2)을 동심원으로 천공된 다수의 통풍구(8)를 통하여 배출됨으로서 카셋트(7)내에 열기가 축척되지 않기 때문에 열로 인한 카세트(7)의 변형을 일으키지 않는다.However, since the heat introduced into the cassette 7 is discharged through a plurality of convexly vented holes 8 through the reel insertion hole 2 of the half down 1, heat is not accumulated in the cassette 7. It does not cause deformation of the cassette 7 due to heat.

위에서 설명한 PLAY 모드시의 릴(5)주행에 있어서는 공기저항과는 큰 문제를 갖고 있지 않지만 릴(5)이 고속주행하는 빨리감기 또는 빨리되감기 모드에서는 세트(7)내부에서 공긱 릴(5)과의 공기 마찰에 의한 저항 즉, 카세트(7) 내부에서 공기가 와류현상을 일으켜 릴(5)의 주행을 방해하게 된다.The reel 5 in the PLAY mode described above does not have a large problem with air resistance. However, in the fast rewind or fast rewind mode in which the reel 5 runs at high speed, the reel 5 and the reel 5 are set inside the set 7. The resistance caused by the friction of the air, that is, the air inside the cassette 7 causes the vortex phenomenon to hinder the running of the reel (5).

그러나, 릴(5)이 주행될때 하프다운(1)의 통풍구(8)를 통하여 카세트(7)내부의 공기를 순환시켜서 릴(5)주위에서 생기는 공기의 와류현상을 최소화하여 줌으로서 릴(5)이 원활한 주행을 하게된다.However, when the reel 5 runs, the air inside the cassette 7 is circulated through the vent hole 8 of the half down 1 to minimize the vortex of air generated around the reel 5, thereby minimizing the reel 5. This makes driving smooth.

그리고, 비디오 테이프 카세트(7)가 보관될때는 첨부도면 제3도와 같이 하프업(3)의 내측에 설치되어서 릴(5)을 지지하는 지지스프링(4)에 의해 릴(5)을 하프다운(1)과 밀착되어 릴(5)이 통풍구(8)는 효율을 높이기 위해서는 릴 삽입공(2)을 중심으로 한 통풍구(8)의 형상을 전 둘레에 형성 할수도 있다.When the video tape cassette 7 is stored, the reel 5 is half-down by the support spring 4 which is installed inside the half-up 3 and supports the reel 5 as shown in FIG. 1) in close contact with the reel 5, the vent 8 may be formed around the periphery of the vent 8 around the reel insertion hole 2 in order to increase the efficiency.

위에서 설명한 바와같은 본고안은, 종래와 같은 밀폐형 구조의 비디오 테이프 카세트에서 릴의 고속 주행시 공기의 와류현상에 의해 릴의 주행을 방해하고, 덱크상에서 외부로부터 유입된 열이 카세트 내부에 계속 축척되어 카세트에 치명적인 해를 끼치던 문제점을, 하프다운의 릴 삽입공을 동심원으로 하는 다수의 통풍구를 형성 하여줌으로서 외부 공기와의 순환에 의해 종래의 문제점을 배제 함으로서 릴의 원활한 주행을 돕고, 테이프의 수명을 연장할 수 있으며, 재료를 절감함으로서 제작원가도 줄일 수 있는 매우 실용적인 고안인 것이다.As described above, the present invention prevents the reel from running due to vortices of air during high-speed running of the reel in a conventionally sealed video tape cassette, and heat introduced from the outside on the deck continues to accumulate inside the cassette. By forming a number of vents with concentric circles with the reel insertion hole of the half-down, the problem of causing serious damage to the reel is eliminated the conventional problem by circulation with the outside air, which helps the reels run smoothly and the life of the tape. It can be extended, and is a very practical design that can reduce the manufacturing cost by saving material.
