본 고안은 비디오 테이프레코오더의 후론트로딩 하우징(FRONT LOADING HOUSING)내에 이물질이나 카셋트테이프의 이중삽입을 방지하기위한 비디오 테이프레코더용 카세트 도어록장치에 관한 것이다.The present invention relates to a cassette door lock device for a video tape recorder for preventing double insertion of foreign matter or cassette tapes in a front loading housing of a video tape recorder.

종래의 비디오 테이프레코오더용 후론트 로딩 하우징의 카세트 도어는 플레이(PLAY)동작중이나 레코오딩(Recording)도중 카세트테이프가 덱크(DECK)에 안착된 상태에서 카세트도어가 자유롭게 열림으로서 각종 이물질이 하우징내에 장입되어 들어가거나 하우징내에 카세트테이프를 이중으로 장입하게되는 경우도 발생되어 덱크의 기능에 손상을 초래하는 결점이 있었다.The cassette door of the front loading housing for a conventional video tape recorder is freely opened while the cassette door is seated on the deck during the PLAY operation or during the recording. In some cases, the cassette tape may be inserted into the housing or double inserted into the housing, which may cause damage to the deck function.

그러므로 본 고안은 이와같은 결점을 해소하기 위하여 릴레이기어에 치합되도록 내면에 괘정돌기를 형성한 록기어(LOCK GEER)를 축설하고 괘정돌기에 의하여 압압되어지는 록레버(LOCK LEVER)에도 괘정돌기를 형성하여 카세트도어를 괘정 또는 해정시켜주도록하는 것이 본 고안의 목적이다.Therefore, in order to solve such a defect, the present invention constructs a lock gear in which a locking protrusion is formed on the inner surface to be engaged with the relay gear and forms a locking protrusion in the lock lever which is pressed by the locking protrusion. It is an object of the present invention to rule or free the cassette door.

본 고안을 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings of the present invention as follows.

비디오 테이프 레코오더세트의 덱크(1)에 구성된 워엄기어(2)에 의해 회전하는 워엄휘일기어(3)와 일체로 형성된 휘일기어(3')가 축설되고, 휘일기어(3')에 치합되어 회전하는 타이밍기어(4)가 축설되며, 타이밍기어(4)에 치합되어 회전하는 반달기어(5)와 일체로 형성된 아암기어(5')와 릴레이기어(6)가 치합되어 상호연동하도록 하우징(9)의 측판(9')에 각각 축설함으로서 카세트테이프(미도시함)를 덱크(1)에 안착되게하는 공지의 것에 있어서, 릴레이기어(6)에 치합되도록 제6도에서와 같이 배면의 일측에 괘정돌기(7')를 형성한 록기어(7)를 축설하고 괘정돌기(7')에 의해 압압되는 괘정돌기(8')를 형성한 록레버(8)를 형성하되, 하우징(9)의 측판(9')에 형성된 삽입공(9")에 좌우이동하도록 록레버(8)일측을 고정홈(10)에 끼워서 고착하여 구성한 것이다.The wheel gear 3 'integrally formed with the worm wheel gear 3 rotated by the worm gear 2 formed on the deck 1 of the video tape recorder set is built up and fitted to the wheel gear 3'. And the timing gear 4 to be rotated is installed, and the arm gear 5 'and the relay gear 6, which are integrally formed with the rotating half moon gear 5, which are meshed with the timing gear 4, are engaged with each other and interlock with each other. In the well-known thing which makes a cassette tape (not shown) rest on the deck 1 by accumulating to the side plate 9 'of (9), respectively, as shown in FIG. 6 so that it may fit to the relay gear 6, The lock gear 7 having the rubbing protrusion 7 'formed on one side is laid out, and the lock lever 8 having the rubbing protrusion 8' pressed by the rubbing protrusion 7 'is formed, and the housing 9 is formed. One side of the lock lever 8 is fitted into the fixing groove 10 so as to move left and right in the insertion hole 9 ″ formed in the side plate 9 ′).

도면중 미설명부호 11은 도어아암레버이다.In the figure, reference numeral 11 denotes a door arm lever.

이와같이 구성된 본 고안의 작용 및 효과를 상세히 설명하면 다음과 같다.Referring to the operation and effects of the present invention configured as described above in detail.

비디오 테이프레코오더의 덱크(1)의 워엄기어(2)에 의해 구동이 시작되면 카세트테이프가 내입되면서 워엄휘일기어 (3)휘일기어(3'), 타이밍기어(4) 반달기어(5) 아암기어(5'), 릴레이기어(6)와 록기어(7)의 순서로 연동되어 회전됨에 의해 록기어(7)의 괘정돌기(7')가 록레버(8)의 괘정돌기(8')에 일치상접하면서 눌러주면 제4도(a)와 같이 록레버(8)의 일단부가 카세트도어(9"')의 내면까지 들어와 상접하게되므로 자동적으로 카세트도어(9"')는 괘정되어 열리지않게 된다.When driving is started by the worm gear 2 of the deck 1 of the video tape recorder, the cassette tape is inserted and the worm wheel gear 3, wheel gear 3, timing gear 4, half moon gear 5 By the rotation of the arm gear 5 ', the relay gear 6, and the lock gear 7 in order, the rubbing protrusion 7' of the lock gear 7 is rotated by the rubbing protrusion 8 'of the lock lever 8. Pressing while coinciding with), one end of the lock lever 8 enters and comes into contact with the inner surface of the cassette door 9 "'as shown in FIG. 4 (a). As a result, the cassette door 9"' is automatically opened. Will not.

한편, 이젝트(EJECT)상태가 되면 덱크(1)의 워엄기어(2)가 역회전하여 워엄휘일기어(3) 휘일기어(3') 타이밍기어(4) 반달기어(5) 아암기어(5') 릴레이기어(6)와 록기어(7)의 순서도 역회전되면서 록레버(8)의 괘정돌기(8')와 압접상태에 있던 록기어(7)의 괘정돌기(7')가 이탈되면서 록레버(8)가 상접하고있던 카세트 도어(9"')의 내면을 이탈하면서 카세트도어(9"')가 해정되어 자유롭게 열림으로 카세트테이프가 빠져나오게 되는 것이다.On the other hand, when the EJECT state is reached, the worm gear 2 of the deck 1 rotates in reverse, and the worm wheel gear 3, the wheel gear 3, the timing gear 4, the half gear gear 5 and the arm gear 5 are rotated. ') The order of the relay gear 6 and the lock gear 7 is also reversed, so that the locking protrusion 8' of the lock lever 8 and the locking protrusion 7 'of the lock gear 7 in the pressure contact state are separated. The cassette door 9 " 'is released while leaving the inner surface of the cassette door 9 "

괘정시키는 과정중 카세트테이프가 덱크(1)에 안착된 후 워엄휘일기어(3)가 회전하고 있던 동일방향으로 약1.5-2회전을 공회전하기 때문에 록기어(7)가 더 회전되어 록레버(8)의 괘정돌기(8')가 록기어(7)의 괘정돌기(7')에 완전히 일치상접되어 카세트도어의 괘정상태가 완전하게 이루어지는 것이다.The lock gear 7 is rotated further by the lock lever 7 because the cassette tape is seated on the deck 1 during the ruling process and idling about 1.5-2 revolutions in the same direction that the worm wheel gear 3 was rotating. The latching projection 8 'of 8) is completely coincided with the latching projection 7' of the lock gear 7 so that the latching state of the cassette door is completed.

따라서, 본 고안은 비디오 테이프레코오더의 사용시. 즉 플레이나 녹화중의 테이프가 안착된 상태에서는 본 고안의 카세트도어록 장치에 의하여 카세트테이프의 이중장입과 이물질등의 장입을 방지하여 줌으로서 덱크의 기능이 손상되지 않도록 하는 효과가 있는 것이다.Therefore, the present invention is in the use of a video tape recorder. In other words, when the tape is seated during play or recording, the cassette door lock device of the present invention prevents the double loading of the cassette tape and the loading of foreign matters, thereby preventing the function of the deck from being impaired.
