본 고안은 비디오 테이프 레코더(이하 브이티알 이라칭한다)의 프론트 로딩장치에 관한 것으로, 특히 덱크구동용 로딩모터를 공용하면서도 그 동력의 절환을 간단한 구조의 기구로써 행할 수 있게한 프론트 로딩장치에 관한 것이다.The present invention relates to a front loading apparatus of a video tape recorder (hereinafter referred to as VTIAL), and more particularly, to a front loading apparatus which allows a deck drive driving motor to be used while switching the power by a simple structure. .

주지된 바와같이, 통상의 브이티알에 있어서는 테이프 카세트를 기기본체의 릴테이블에 장착시키는 위한 카세트 프론트 로딩부가 갖추어지고, 릴테이블에 장착된 테이프 카세트에서 테이프를 인출하고 헤드드럼에 감아 녹음 및 재생의 모드가 행하여 질 수 있게하는 테으프 로딩장치를 포함된 덱크 구동부가 갖추어져 있으며, 프론트 로딩부와 텍크 구동부의 동작은 순차적으로 진행되는 것이 보통이다.As is well known, in the conventional VTIAL, a cassette front loading section for mounting the tape cassette to the reel table of the machine body is provided, and the tape is withdrawn from the tape cassette mounted on the reel table and wound on the head drum for recording and playback. A deck driving unit including a tape loading device to enable a mode is provided, and the operations of the front loading unit and the tex driving unit are generally performed sequentially.

종래에도 하나의 모터로 프론트 로딩부와 덱크 구동부를 구동시키는 방식이 제한되고 있으나, 이러한 종래기술의 프론트 로딩장치는 프론트 로딩장치는 프론트 로딩메카니즘의 동력절환을 위한 수단이 많은 부품수를 요하는 복잡한 구조로 되어 제품의 원가가 상승되고 원활한 작동을 기하지 못하는 문제점이 있었다.Conventionally, the method of driving the front loading unit and the deck driving unit with a single motor is limited. However, the front loading apparatus of the prior art has a complicated structure requiring a large number of parts, which means that the front loading apparatus has a means for power switching of the front loading mechanism. Due to the structure, the cost of the product was increased and there was a problem in that it could not operate smoothly.

본 고안은 종래의 문제점을 해소하기 위하여 안출한 것으로 암기어와 윔기어 사이에 불연속기어가 일체로 형성된 연결기어를 설치하여 불연속기어의 기어부가 암기어의 기어부에 맞물리게 함으로써 연결기어가 덱크구동용 캠기어를 구동시큰 로딩모터의 구동력으로 회저하면 암기어가 회전하여 카세트 로딩이 행해지게 하고 로딩이 완료된 후에는 암기어와 불연속기어의 절치부가 대응되어 로딩모터의 동력이 차단되게 함으로써 댁크구동용 캠기어가 원할하게 작동될수 있게한 바와같이, 카세트 하우징(1)의 일측판(2)에 형성된 ㄱ 자형 안내공(3)에 카세트 캐리어(4)의 일측판에 형성된 안내핀(5)이 삽입되어 그 안내핀(5)이 암기어(6)의 장공(7)에 삽입되고 덱크 구동용 캐기어(8)가 로디모터(9)의 회전축(10)에 고정된 웜(11)에 치합되며 그 웜(11)에 평기어(12)가 일체로 형성된 웜기어(13)가 치합되는 것에 있어서, 상기 암기어(6)와 웜기어(13)의 사이에 연결기어(14)를 축착하고 그 연결기어(14)의 내측면에는 기어부(15)와 절치부(16)를 가지는 불연속기어(17)를 형성하되, 절치부(16)의 직경이 기어부(15)의 이끌원직경과 같은 직경을 갖도록 형성하여, 불연속기어(17)를 형성하되, 절치부(16)의 직겨이 기어부(6')에 치합되게 하며(제2도), 암기어(6)의 기어부(6')일측단부에는 그 기어부(6')의 이뿌리원직경과 같은 직경을 가지는 절치부(18)를 형성하여 그 절치부(18)와 불연속기어(17)의 절치부(16)가 제3도와같이 로딩이 완료되는 위치에서 대응되게한 것이다.The present invention was devised to solve the conventional problems, and the connecting gear is installed in the deck drive cam by engaging the gear part of the discontinuous gear with the gear part of the female gear by installing a connecting gear in which the discontinuous gear is integrally formed between the female gear and the worm gear. When the gear is rotated by the driving force of a large loading motor, the arm gear rotates to allow cassette loading to be carried out, and after the loading is completed, the gears of the female gear and the discontinuous gear correspond to the cutoff of the loading motor so that the drake driving cam gear is desired. As can be operated, the guide pin (5) formed in one side plate of the cassette carrier (4) is inserted into the a-shaped guide hole (3) formed in the one side plate (2) of the cassette housing (1) (5) is inserted into the long hole (7) of the arm gear (6) and the deck drive gear (8) is meshed with the worm (11) fixed to the rotating shaft (10) of the Lodi motor (9) and the worm (11) Spur gears In the case where the worm gear 13 formed integrally with 12 is engaged, the connecting gear 14 is compressed between the female gear 6 and the worm gear 13 and a gear part is provided on the inner surface of the connecting gear 14. A discontinuous gear 17 having a cutout portion 16 and a cutout portion 16 is formed, and the cutout portion 16 is formed to have a diameter equal to the lead diameter of the gear portion 15. To form the upper end of the incisor 16 to the gear part 6 '(FIG. 2), and at one end of the gear part 6' of the female gear 6, the gear part 6 '. Indentation portion 18 having the same diameter as the root diameter of the root is formed so that the incision portion 18 and the distal portion 16 of the discontinuous gear 17 correspond to the position where the loading is completed as shown in FIG. .

이와같이된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention as described above is as follows.

제2도는 카세트가 로딩되는 상태를 보인것으로 이상태에서는 암기어(6)의 기어부(6')와 불연속기어(17)의 기어부(15)가 치합되어 있으므로, 로딩모터(9)의 동력은 축(10), 웜기어(13), 평기어(12), 연결기어(14) 및 불연속기어(17)를 차례로 거쳐 암기어(6)에 전달되어 암기어(6)가 회전하게 되므로 통상의 카세트 로딩 동작을 수행하게 된다.2 shows a state in which the cassette is loaded. In this state, the gear part 6 'of the female gear 6 and the gear part 15 of the discontinuous gear 17 are engaged, so that the power of the loading motor 9 Since the gear 10 is rotated through the shaft 10, the worm gear 13, the spur gear 12, the coupling gear 14, and the discontinuous gear 17, in turn, the female gear 6 is rotated. The loading operation will be performed.

제3도는 카세트의 로딩이 완료된 후의 상태를 보인것응로 이상태에서는 카세트가 텍크의 릴레이블에 안착되고 암기어(6)의 통상의 카세트 압착장치(릴테이블과 압착되는 도시를 생략함)에 의하여 덱크상에 압착지지되고 있다.3 shows the state after the loading of the cassette is completed. In this state, the cassette is seated in the revelable of the tex and the conventional cassette pressing device (not shown to be pressed against the reel table) of the arm gear 6 is omitted. It is crimped and supported on the deck.

이때에 암기어(6)와 불연속기어(17)의 절치부(18) (16)가 대응되는 위치에 도달해있고 암기어(6)가 카세트를 압착하고 있는 관계로 암기어(6)는 반시계방향의 모멘트를 받게된다. 따라서 암기어(6)의 마지막 치(6")가 불연속기어(17)의 절치부(16) 외주면에 압력을 가하게 된다.At this time, the arm gear 6 and the discontinuous gear 17 have reached the corresponding positions of the cutouts 18 and 16, and the arm gear 6 is pressed in half because the arm gear 6 presses the cassette. You will receive a clockwise moment. Therefore, the last tooth 6 "of the arm gear 6 exerts a pressure on the outer peripheral surface of the incisor 16 of the discontinuous gear 17.

이와같이 카세트 로딩이 완료되어 암기어(6)의 기어부(6')의 마지막 치(6")가 불연속기어(17)의 기어부(5)마지막 치(15')에서 이탈된후에는 불연속기어(17)가 계속되는 로딩모터(9)의 구동에 의하여 반시계 방향으로 더 회전 하더라도 암기어(6)와 불연속기어(17)의 절치부(18) (16)에 의하여 로딩모터(9)의 구동력이 암기어(6)에 전달되지 않게 되어 웜(11)에 연동되는 덱크 구동용 캠기어(8)가 자유자재로 회전하여 덱크의 필요한 동작을 행할 수 있게 되는 것이다.After the cassette loading is completed and the last tooth 6 "of the gear portion 6 'of the arm gear 6 is disengaged from the last tooth 15' of the gear portion 5 of the discontinuous gear 17, the discontinuous gear The driving force of the loading motor 9 by the cutouts 18 and 16 of the female gear 6 and the discontinuous gear 17 is further rotated counterclockwise by the driving of the loading motor 9 which is continued. It is not transmitted to the arm gear 6 so that the deck driving cam gear 8 interlocked with the worm 11 can freely rotate to perform the required operation of the deck.

한편 카세트를 언로딩시켜 이젝트한는 경우에는 로딩모터(9)가 역회전 함에 따라 불연속기어(17)가 시계방향으로 회전하여 불연속기어(17)의 마지막 치(15')가 암기어(6)의 마지막 치(6")에 치합되는 위치에 이르면 암기어 암기어(6)는 이미 반시계방향의 모멘트를 받고 있으므로 그 탄력에 의하여 불연속기어(17)와 암기어(6)의 마지막 치(15') (6")가 확실히 치합되고 그 이후로는 불연속기어(17)의 회전력이 암기어(6)에 전달되어 통상의 카세트 이젝트 동작을 행하게 된다.On the other hand, when the cassette is unloaded and ejected, as the loading motor 9 rotates in reverse, the discontinuous gear 17 rotates in the clockwise direction so that the last tooth 15 'of the discontinuous gear 17 is rotated by the female gear 6. At the position where the last tooth (6 ") is engaged, the female gear arm gear (6) is already receiving a counterclockwise moment, and therefore the last tooth (15 ') of the discontinuous gear (17) and the arm gear (6) by its elasticity. 6 " is securely engaged thereafter, and the rotational force of the discontinuous gear 17 is transmitted to the female gear 6 to perform a normal cassette ejection operation.

상기한 바와같이된 본 고안은 암기어와 웜기어와 웜기어 사이에 불연속기어를 갖는 연결기어를 설치하여 불연속기어와 암기어의 기어부 및 절치부가 로딩시 또는 로딩완료시에 선택적으로 대응되게한 간단한 구성에 의하여 텍크구동용 로딩 모터로 프론트 로딩부를 구동시키면서 프론트로딩이 완료된 상태에서는 동력이 차단되게하여 암기어의 로딩위치를 유지하고 덱크 구동용 캠기어르 원활하게 구동시킬 수 있게 되므로, 제푸므이 원가절감에 기어하고 고장을 제하에 기여하여 제품의 신뢰성을 향상시키는 이점이 있다.The present invention, as described above, by installing a connecting gear having a discontinuous gear between the female gear and the worm gear and the worm gear by a simple configuration to selectively correspond to the gear portion and the incidence portion of the discontinuous gear and the female gear when loading or loading completion While driving the front loading unit with the tec drive loading motor, the power is cut off when the front loading is completed to maintain the loading position of the arm gear and to drive the deck driving cam gear smoothly. And contributes to the elimination of failures, thereby improving the reliability of the product.
