본 고안은 테이프 레코더에 있어서, 동작반경을 적게 하고 구조를 간단하게 한 핀치로울러의 구동장치에 관한 것이다.The present invention relates to a pinch roller drive device having a small operation radius and a simple structure in a tape recorder.
종래의 핀치로울러 구동장치를 보면, 테이프가 로딩동작을 할 때 핀치로울러용 캠기어가 동작되고 이의 동작에 따라 여러개의 링크가 동작하면서 핀치로울러를 캡스턴축에 접촉하도록 되어 있었다.In the conventional pinch roller driving device, when the tape is loading, the pinch roller cam gear is operated and several links are operated according to the operation thereof so that the pinch roller contacts the capstan shaft.
그러나, 이와 같은 것은 동작반경이 크게되므로 레코더 전체가 부피가 커져야 하고 따라서 이를 소형화하기에 곤란하였으며, 캠기어와, 여러개의 링크에 의하여 동작을 시키므로서 동력전달의 손실이 발생되어 동작을 원활하게 하기 곤란한 점등의 문제점을 지니고 있었다.However, such a large operating radius requires the entire recorder to be bulky and therefore difficult to miniaturize. Thus, the operation is performed by cam gears and several links, resulting in loss of power transmission and smooth operation. It had a problem of difficult lighting.
본 고안은 상기와 같은 종래의 문제점을 감안하여 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been devised in view of the above-described conventional problems, and will be described in detail with reference to the accompanying drawings.
데크(1)의 일방에 로딩기어(1)에 의해 구동되는 링기어(3)를 가이드롤(4)에 설치하고 링기어(3)의 일단에는 섹터기어(5)를 설치하며, 링기어(3)의 일측에 섹터기어(5)에 의해 구동하는 구동기어(6)를 설치하고 이에 회동핀(7)을 편심되게 설치한다.A ring gear 3 driven by the loading gear 1 on one side of the deck 1 is installed on the guide roll 4, and one end of the ring gear 3 is provided with a sector gear 5, and a ring gear ( The drive gear 6 driven by the sector gear 5 is installed on one side of 3), and the pivot pin 7 is eccentrically installed thereon.
회동핀(7)에는 장공(9)을 일측에 형성한 링크(8)를 스냅링(17)과 스프링(10)으로 탄력설치하고 이외 일단을 축(12)을 가진 핀치암(11)에 힌지(13)로 유설하며 축(12)에는 베어링(15)을 가진 핀치로울러(14)를 설치하고 핀치암(11)의 일단에는 회동축(16)을 스냅링(17)으로 설치한다.The pivot pin 7 has a link 8 having a long hole 9 formed on one side, and is elastically installed with the snap ring 17 and the spring 10 and the other end is hinged to the pinch arm 11 having the shaft 12 ( 13) and a pinch roller 14 having a bearing 15 is installed on the shaft 12, and the pivot shaft 16 is installed on one end of the pinch arm 11 by a snap ring 17.
구동기어(6)의 일측에는 봉체(18)를 설치하여 회동핀(7)과의 사이에 비틀림스프링(19)을 설치한다.The rod 18 is provided on one side of the drive gear 6 to install a torsion spring 19 between the pivot pin 7.
구동기어(6)와 핀치암(11)의 사이에 플라이휠(22)과 모터(20)에 의해 구동되는 캡스턴축(21)을 설치한다.A capstan shaft 21 driven by a flywheel 22 and a motor 20 is provided between the drive gear 6 and the pinch arm 11.
이상과 같이 구성된 본 고안은 제3도와 제4도에서와 같이 동작하는 것으로 이를 상세히 설명하면 다음과 같다.The present invention configured as described above operates as shown in FIG. 3 and FIG. 4.
테이프를 로딩시키기 위하여 데크(11)의 일방에 설치한 로딩기어(2)를 구동시키면, 링기어(3)가 회동하면서 로딩암을 작동시켜 테이프를 로딩시키게 된다.When the loading gear 2 installed on one side of the deck 11 is driven to load the tape, the ring gear 3 rotates to operate the loading arm to load the tape.
이와 같이 링기어(3)가 회동하면 이에 설치된 섹터기어(5)가 구동기어(6)를 회전시키고 회동편(7)이 회동된다.When the ring gear 3 rotates in this way, the sector gear 5 installed therein rotates the drive gear 6 and the rotation piece 7 rotates.
회동핀(7)이 회동하면 이에 장공(9)이 삽입된 링크(8)가 구동기어(6)와 함께 회동하여 이의 일단이 힌지(13)로 유설된 핀치암(11)을 잡아당기게 되고 핀치암(11)은 회동축(16)을 중심으로 제4도와 같이 회동하여 이에 설치된 핀치로울러(14)를 캡스턴축(21)에 접촉되게 동작시킨다.When the pivot pin 7 rotates, the link 8 into which the long hole 9 is inserted rotates together with the drive gear 6 so that one end of the pivot pin 11 pulls the pinch arm 11 held by the hinge 13. The arm 11 pivots about the rotational shaft 16 as shown in FIG. 4 to operate the pinch roller 14 installed therein to contact the capstan shaft 21.
이때 비틀림스프링(19)이 회동핀(7)과 같이 회동하면서 비틀림스프링(19)의 중심에서 탄력이 이동되게 되며 이에 따라 링크(8)가 일측으로 록킹되게 된다.At this time, while the torsion spring 19 is rotated like the pivot pin 7, the elasticity is moved at the center of the torsion spring 19, and thus the link 8 is locked to one side.
스프링(10)은 링크(8)와 회동핀(7)을 장공(9)에서 탄력있게 동작토록 한다.The spring 10 allows the link 8 and the pivot pin 7 to operate elastically in the long hole 9.
한편, 섹터기어(5)가 구동기어(6)에서 벗어나게 되면 구동기어(6)의 회동이 정지되고 이에 연결된 각 부품이 모두 정지하며 핀치로울러(14)가 캡스턴축(21)에 접촉된 상태에서 모터(20)를 구동시키고 핀치로울러(14)와 캡스턴축(21)을 구동시키므로서 테이프가 주행하게 된다.On the other hand, when the sector gear 5 is moved out of the drive gear 6, the rotation of the drive gear 6 is stopped, and all the components connected thereto are stopped, and the pinch roller 14 is in contact with the capstan shaft 21. The tape travels by driving the motor 20 and driving the pinch roller 14 and the capstan shaft 21.
이와 같이 로딩작동이 완료되어 테이프가 주행하다가 테이프를 언로딩시키면, 로딩기어(2)가 역회전하여 링기어(3)를 복귀시키고 링기어(3)가 복귀되면서 이에 설치된 섹터기어(5)가 구동기어(6)를 역으로 회동시켜 링크(8)와 핀치로울러(14)가 비틀림스프링(19)의 탄력을 받으면서 상기의 역으로 동작하여 핀치로울러(14)가 캡스턴축(21)에서 떨어지게 된다.When the loading operation is completed and the tape is driven and the tape is unloaded, the loading gear 2 is rotated in reverse to return the ring gear 3 and the ring gear 3 is returned, so that the sector gear 5 installed thereon By rotating the drive gear 6 in reverse, the link 8 and the pinch roller 14 receive the elasticity of the torsion spring 19 and operate in the reverse direction so that the pinch roller 14 falls off the capstan shaft 21. .
이와 같이 동작되는 본 고안의 섹터기어(5)는 링기어(3)가 테이프를 로딩시키는 시간에 맞추어 설치위치를 설정하여 설치된다.The sector gear 5 of the present invention operated as described above is installed by setting the installation position in accordance with the time when the ring gear 3 loads the tape.
이상과 같은 본 고안은 좁은공간내에서도 간단한 구조로 동작이 원활하게 안정되게 작동할 수 있으며 동작반경이 매우 적으므로 레코더의 부피를 소형화 시킬 수 있는 점등의 특징을 지닌 것이다.The present invention as described above has a feature of lighting that can reduce the volume of the recorder because the operation structure can be operated smoothly and stably even in a narrow space and the operation radius is very small.
