본 고안은 디지탈 오디오 테이프 레코더(DAT)에 관한 것으로, 특히 카세트의 착탈구조에 적당하도록 한 프론트 로딩식 카세트 업다운 장치에 관한 것이다.The present invention relates to a digital audio tape recorder (DAT), and more particularly, to a front loading cassette up-down apparatus adapted to a removable structure of a cassette.

종래의 카세트 테이프 업다운 장치는 제 1 도 및 제 2 도에 도시한 바와같이, 카세트(1)가 올려지는 카세트 테이프홀더(2)의 양측에 안내돌기(2a)를 각각 설치하고 안내돌기(2a)를 가지는 테이프홀더(2)의 외측에서 좌측가동판(3) 및 우측가동판(4)을 조립한후 도어(5)를 좌측가동판(3) 및 우측가동판(4)에 조립하였으며, 이때 좌측가동판(3) 및 우측가동판(4)에는 안내장공을 형성하고 그 안내장공에 연결봉 및 안내돌기(2a)를 삽입하였다(안재장공, 연결봉은 제 5 도 38번, 37번 각각 참조). 또한 동작레버(6)에는 요홈(6a)을 형성하고 한끝단에는 레버돌기(6b)를 설치하여 구동기어(7)의 결사면(7a)에 접동하도록하였다. 그리고 하측가이드판(8) 및 상측가이드판(9)사이에 동작레버(6)를 지지봉(6')을 통해서 고정하고 지지봉(6')의 단부에는 링(10)을 체결 하였으며, 하측가이드판(8) 및 상측가이드판(9)사이에 삽입되는 좌측가동판(3)에는 구동기어(7)에 맞물리는 래크(3a)가 구비된 구조로 되어 있다. 도면에서 11은 구동모터이고, 12는 구동모터의 회전축(11')에 고정된 구동풀리이며, 13은 그 구동풀리(12)와 구동기어(7)의 하측풀리(7b)를 연결하는 벨트를 보인 것이고, 14는 동작레버(6)를 하향 탄지하는 스프링을 보인 것이다.In the conventional cassette tape up-down apparatus, as shown in FIGS. 1 and 2, guide protrusions 2a are respectively provided on both sides of the cassette tape holder 2 on which the cassette 1 is placed, and guide protrusions 2a are respectively provided. After assembling the left movable plate 3 and the right movable plate 4 from the outside of the tape holder 2 having a side, the door 5 was assembled to the left movable plate 3 and the right movable plate 4, wherein the left movable plate 3 ) And the right movable plate 4 to form a guide hole, and the connecting rod and the guide protrusion 2a were inserted into the guide hole (see eyepiece hole and connecting rod, respectively, FIGS. 5 and 38 and 37). In addition, a groove 6a is formed in the operation lever 6, and a lever protrusion 6b is installed at one end to slide on the engagement surface 7a of the drive gear 7. Then, between the lower guide plate 8 and the upper guide plate 9, the operating lever 6 is fixed through the supporting rod 6 ', and the ring 10 is fastened to the end of the supporting rod 6'. The left movable plate 3 inserted between the 8 and the upper guide plate 9 has a structure in which a rack 3a is engaged with the drive gear 7. In the drawing, 11 is a drive motor, 12 is a drive pulley fixed to the rotating shaft 11 'of the drive motor, and 13 is a belt connecting the drive pulley 12 and the lower pulley 7b of the drive gear 7. As shown, 14 shows a spring touching the operating lever 6 downward.

이와같이 된 종래의 구동장치는 구동모터(11)에 전원이 공급되면, 벨트(13)를 통하여 구동기어(7)에 동력이 전달되며 구동기어(7)가 제 1 도와 같이 반시계방향으로 회전하게되면 이에 좌측가동판(3)의 래크(3a)가 맞물려 있으므로 좌측 가동판(3)의 몸체전체가 제 2 도의 좌측방향으로 이동하게되어 경사면(7a)의 사각점과 레버돌기(6b)가 만나는 부근에서 테이프홀더(2)의 안내돌기(2a)가 동작레버(6)의 요홈(6a)에 삽입되고, 동작레버(6)가 스프링(14)으로 하향탄지되어 있으므로 구동기어(7)가 회동함에 따라 경사면(7a)을 타고 하방향으로 이동하여 테이프홀더(2)를 하향으로 누르게되어 테이프홀더(2)에 삽입된 카세트테이프(1)가 하측의 일정위치로 이동하게 되어 주행준비 상태로 된다.In the conventional drive device as described above, when power is supplied to the drive motor 11, power is transmitted to the drive gear 7 through the belt 13 so that the drive gear 7 rotates counterclockwise as in the first degree. When the rack 3a of the left movable plate 3 is engaged with it, the entire body of the left movable plate 3 is moved in the left direction of FIG. 2 so that the blind spot of the inclined surface 7a and the lever protrusion 6b meet each other. Since the guide protrusion 2a of the tape holder 2 is inserted into the recess 6a of the operating lever 6 and the operating lever 6 is supported downward by the spring 14, the driving gear 7 rotates. Accordingly, the tape holder 2 is moved downward by moving downward on the inclined surface 7a so that the cassette tape 1 inserted into the tape holder 2 moves to a predetermined position on the lower side and is ready for travel.

테이프(1)취출동작은 구동모터(11)에 역방향 회전을 주면 상기 동작의 역으로 행하여진다.The tape 1 take-out operation is performed in the reverse of the above operation when the drive motor 11 is rotated in the reverse direction.

그러나, 이와같은 종래의 장치는 구동모터(11)를 별도로 설치하여 원가상승의 원인이 되고 있으며 구동모터(11) 및 구동기어(7)의 설치를 위하여 많은 설치공간이 요구되어 최적한 설계에 위배되는 매우 불리한 결함을 갖고 있었다.However, such a conventional device causes a cost increase by separately installing the drive motor 11, and a lot of installation space is required for the installation of the drive motor 11 and the drive gear 7, thus violating the optimum design. Which had very disadvantageous defects.

본 고안은 이와같은 종래의 결함을 해소하기 위하여 안출한 것으로 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a conventional defect as described in detail by the accompanying drawings as follows.

On The long hole 36a fixed to the fixed intermediate protrusion 35 is formed by pressing one end of the intermediate body 36 having the protrusion 36a inserted into the recess 32a of the operating lever 32 and forming the other end of the intermediate body 36. ) Inserts and connects the ends of the connecting rods 37 fixed to the cassette holder 21, and forms guide guide holes 38 perpendicular to both side movable plates 26 and 27, respectively. The guide protrusions 21a fixed to the ends of (37) and both side surfaces of the cassette holder 21 were respectively fixed.

또한, 공지 캡스턴모터(39)의 동력을 풀리와 벨트를 이용해 동력전달계(40)에 연결하고 동력전달계(40)에 구비된 웜(41)을 상기 웜기어(29)에 교합시켰다.In addition, the power of the known capstan motor 39 is connected to the power transmission system 40 using a pulley and a belt, and the worm 41 provided in the power transmission system 40 is engaged with the worm gear 29.

도면에서 43은 상기 연결레버(34)를 하향으로 탄력 지지하는 인장스프링을 보인 것이다.43 shows a tension spring that elastically supports the connecting lever 34 downward.

이와같이 된 본 고안의 동작은 제 4 도 및 제 5 도에서 보듯이 캡스턴모터(39)에서 동력전달계(40)를 통해 웜(41)에 동력이 전달되면 이와 맞물린 웜기어(29)가 회전함에 따라 캠(28)도 회전을 하여 캠홈(28a)(28b)도 웜기어회전축(30)을 중심으로 회전하면서 캠홈(28a)에 삽입설치한 접동핀(34a)를 하향으로 회전시킨다.As shown in FIGS. 4 and 5, the cam according to the rotation of the worm gear 29 engaged with the worm 41 rotates when the power is transmitted from the capstan motor 39 to the worm 41 through the power train 40. (28) also rotates, while the cam grooves 28a and 28b also rotate about the worm gear rotation shaft 30 to rotate the sliding pin 34a inserted into the cam groove 28a downward.

또한 캠(28)이 회전함에 따라 이에 맞물린 래크(26a)를 좌측으로 이동시킴으로써 가동판(26)(27)에 설치한 전체 구성품이 이동하게 되며 캠(28)에 일정각 회전하게되면 접동핀(34a)과 단부 캠홈(28b)이 마추지게 되며 이 위치에서 중간체(36)이 요홈돌기(36a)는 동작레버(32)의 요홈(32a)에 삽입되며 캠(28)이 더욱 회전하게 되면 스프링(43)의 장력에 의해 접동핀(34a)이 단부캠홈(28b)의 최하단부까지 내려오게 되도록(제 5 도) 연결레버(34)가 결합봉(31)을 기준으로 시계방향으로 회전되고 또한 중간체(36)가 중간돌기(35)를 중심으로 시계방향 회전을 행한다. 이때 중간체(36)의 끝단의 장공(36b)의 연결봉(37) 역시 아래방향으로 이동한다. 이때 연결봉(37)과 테이프홀더(21)측에 설치한 안내돌기(21a)가 양측가동판(26)(27)의 안내장공(38)에 삽입되어 있으므로 안내장공(38)에 가이드되어 하측방향으로 운동하면서 카세트 테이프(22)의 안착기능이 행하여진다.In addition, as the cam 28 rotates, the entirety of the components installed on the movable plates 26 and 27 is moved by moving the rack 26a engaged to the left side. When the cam 28 rotates at a predetermined angle, the sliding pin ( 34a) and the end cam groove 28b are crushed. In this position, the intermediate body 36 is the groove projection 36a is inserted into the groove 32a of the operating lever 32, and when the cam 28 is further rotated, the spring ( The connecting lever 34 is rotated clockwise with respect to the coupling rod 31 so that the sliding pin 34a is lowered to the lowermost end of the end cam groove 28b by the tension of 43). 36 performs clockwise rotation about the middle projection 35. At this time, the connecting rod 37 of the long hole 36b at the end of the intermediate body 36 also moves downward. At this time, since the guide protrusion 21a installed on the connecting rod 37 and the tape holder 21 is inserted into the guide hole 38 of both movable plates 26 and 27, it is guided by the guide hole 38 and moves downward. The seating function of the cassette tape 22 is performed while moving.

역으로, 카세트테이프(22)를 취출하고자 하는 경우에는 캡스턴모터(39)를 역방향으로 회전시키면 위에서 언급한 작용의 역장용으로 카세트테이프(22)가 취출된다.On the contrary, in the case where the cassette tape 22 is to be taken out, when the capstan motor 39 is rotated in the reverse direction, the cassette tape 22 is taken out for the force field of the above-mentioned action.

이상에서 설명한 바와같은 본 고안은 카세트의 프론트 로딩을 위하여 별도의 구동모터(11)를 별도로 설치할 필요가 없으므로 원가절감을 기할 수 있을 뿐아니라 구동기어(7)에 설치한 경사면(7a)을 없앰과 아울러 캠(28)의 내측에 캠홈(28a)(28b)을 설치하고 웜기어(29)를 수직으로 설치하여 외부 사용공간을 최소화함으로써 최적화 설계를 기하고 제품의 소형화를 기하는 이점이 있다.As described above, the present invention does not need to separately install a separate drive motor 11 for the front loading of the cassette, thereby reducing the cost and removing the inclined surface 7a installed on the drive gear 7. In addition, the cam grooves 28a and 28b are installed inside the cam 28, and the worm gear 29 is vertically installed to minimize the external use space, thereby achieving an optimized design and miniaturization of the product.
