본 고안은 프론트 로우딩 방식의 VTR에 있어 테이프 카세트가 정상적으로 삽입이 되지 않을시에는 하우징내에 테이프 카세트가 삽입되지 못하도록하는 비디오 테이프 레코오더의 테이프 카세트 오삽입 방지 장치에 관한 것으로, 특히 테이프 카세트가 삽입되는 하우징 저면의 전방 소정 위치에 원호상의 슬립면과 괘지돌턱을 갖춘 제동레버를 스프링으로 상향 탄지하여 삽입 통로상으로 돌출되게 축설시키고 테이프 카세트도어에는 제동레버와 대응되는 소정 위치에 제동레버의 괘지돌턱이 통과되는 통공을 구비하여 테이프 카세트가 정상적으로 삽입되면 제동 레버 원호상의 슬립면이 테이프 카세트 저면에 접동하향되어 제동레버가 해제되고, 테이프 카세트가 비 정상적으로 삽입되면 제동레버의 괘지돌턱에 의해 삽입이 되지 않도록 한 비디오 테이프 레코오더의 테이프 카세트 오삽입 방지 장치인 것이다.The present invention relates to a tape cassette misinsertion prevention device of a video tape recorder, which prevents a tape cassette from being inserted into a housing when a tape cassette is not normally inserted in a front loading type VTR. A brake lever having an arc-shaped slip surface and a ruler bump at a predetermined position in front of the housing bottom is projected upward with a spring and laid out to protrude onto the insertion path. When the tape cassette is normally inserted with the through hole passing through, the slip surface of the arc of the brake lever is slid downward to the bottom of the tape cassette, and the brake lever is released. Avoid video te Program will tape cassette erroneous insertion preventing device record orders.
종래 비디오 테이프 레코오더의 테이프 카세트 오삽입 방지 장치를 보면 여러 방법이 있었으나, 통상적으로 그 구성이 복잡하고, 그리고 오 삽입 감지 상태가 불확실하여 오삽입이 빈번히 발생되고 따라 기기 부품을 파손시키게되는 등의 많은 문제점이 있었다.[0003] In the tape cassette misinsertion prevention apparatus of a conventional video tape recorder, there are various methods. However, in general, the configuration thereof is complicated, and a misinsertion detection state is uncertain, and thus, misinsertion occurs frequently, resulting in damage to device components. There were many problems.
본 고안은 이와 같은 문제점을 감안하여, 하우징의 저면 소정위치에 원호상의 슬립면과 괘지돌턱을 갖춘 제동레버를 삽입 통로상으로 돌출되게 축설하고, 테이프 카세트의 도어에는 제동레버와 대응되는 동일위치에 제동레버에 구성시킨 괘지돌턱이 통과되는 통공을 구비하여 테이프 카세트의 정상 삽입 확인을 정확하고도 안정되게하고, 오삽입을 확실히 방지할 수 있도록 안출한 것으로, 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.In view of such a problem, the present invention provides a braking lever having an arc-shaped slip surface and a locking projection at a predetermined position on the bottom of the housing so as to protrude onto an insertion path, and the door of the tape cassette is located at the same position as that of the braking lever. It is provided with a through hole through which a rubbing block configured in the brake lever is passed to ensure accurate and stable insertion of the tape cassette and to prevent erroneous insertion. Same as
본 고안은 테이프 카세트(1)가 삽입되는 하우징(2)의 저면(2-1)소정위치에 괘지돌턱(3-1)과 괘지돌턱(3-1)의 높이에 비례하며 원호상으로 이루어지는 슬립면(3-2) 그리고 하우징의 저면(2-1)에 접촉되는 정지턱(3-3)을 일체로 갖춘 제동레버(3)를 스프링(4)으로 상향탄지하여 하우징의 삽입 통로로 돌출되게 축설하고, 테이프 카세트(1)의 도어(1-1)저면에는 제동레버(3)와 대응되는 동일위치상에 제동레버(3)의 괘지돌턱(3-1)이 통과되는 통공(1-1A)을 구성시키어서 된 것이다.According to the present invention, a slip made of an arc shape is proportional to the height of the rubbing 3-1 and the rubbing 3-1 at a predetermined position of the bottom 2-1 of the housing 2 into which the tape cassette 1 is inserted. The brake lever 3 having the surface 3-2 and the stopping jaw 3-3 integrally in contact with the bottom surface 2-1 of the housing is upwardly supported by a spring 4 to protrude into the insertion passage of the housing. And a through hole 1-1A through which the locking projection 3-1 of the brake lever 3 passes on the bottom of the door 1-1 of the tape cassette 1 at the same position corresponding to the brake lever 3; ) Is made up of.
이와같이 구성된 본 고안의 작용 효과를 설명하면, 제 3 도에서는 테이프 카세트(1)가 정상적으로 삽입되는 상태를 보인 것으로, 테이프 카세트(1)가 정상적으로 삽입되면, 테이프 카세트(1)의 도어(1-1)에 구비시킨 통공(1-1A)이 제동레버(3)의 괘지돌턱(3-1)이 일치되어 통공(1-1A)내로 괘지돌턱(3-1)이 통과되고 이와 동시에 제동레버(3) 원호면의 슬립면(3-2)에 테이프 카세트 도어(1-1)저면이 접동되면서 제동레버(3)를 하향시키어 해체시키고, 테이프 카세트가 삽입되게 하고, 그리고 제 4 도에서는 테이프 카세트(1)후면의 저면 모서리부가 제동레버(3)의 괘지돌턱(3-1)에 접촉되어 테이프 카세트의 삽입이 되지 못하도록 한 것으로, 간단한 구조로 테이프 카세트의 비 정상적인 삽입을 정확하고도 확실히 확인하여 오삽입을 완전 방지할 수 있는 효과가 있는 것이다.Referring to the operation and effect of the present invention configured as described above, FIG. 3 shows a state in which the tape cassette 1 is normally inserted. When the tape cassette 1 is normally inserted, the door 1-1 of the tape cassette 1 is shown. The through hole (1-1A) provided at the) coincides with the ruled stone bump (3-1) of the brake lever (3) and passes through the ruled stone bump (3-1) into the through hole (1-1A) and at the same time the brake lever (3) As the bottom of the tape cassette door 1-1 slides on the slip surface 3-2 of the arc surface, the brake lever 3 is lowered and disassembled, and the tape cassette is inserted. 1) The bottom edge of the rear surface is in contact with the locking projection (3-1) of the brake lever (3-1) to prevent the insertion of the tape cassette. It is effective to prevent insertion completely .
