본 고안은 디지탈 오디오 테이프 레코더의 릴구동장치에 관한 것으로, 특히 릴을 별도의 구동모터를 사용하지 않고 캡스턴 모터로 구동되는 캡스턴풀리에 연동시켜 테이프의 정상 주행구동과 고속탐색주행을 모두 할수 있도록 한 디지탈 오디오 테이프 레코더의 릴구동장치에 관한 것이다.The present invention relates to a reel driving device of a digital audio tape recorder. In particular, the reel is connected to a capstan pulley driven by a capstan motor without using a separate driving motor so that both the normal driving driving and the high speed search driving of the tape can be performed. A reel driving device for a digital audio tape recorder.

일반적으로 디지탈 오디오 테이프 레코더에서는 테이프를 정상주행(녹음, 재생시)시킬 수 있어야 함은 물론 정상주행의 200배속으로 되는 고속 탐색이 가능할 것이 요구된다.In general, a digital audio tape recorder needs not only to be able to drive the tape normally (when recording and playing), but also to be able to search at a high speed of 200 times normal driving.

그런데 디지탈 오디오 테이프 레코더의 캡스턴을 속도 변화가 너무 심하기 때문에 캡스턴 모터 하나로서는 정상주행구동과 고속탐색구동을 모두 할 수가 없어 고속탐색을 의한 구동장치가 정상주행을 위한 구동장치와는 별도로 설치하고 있었다.However, because the capstan of the digital audio tape recorder has too much speed change, one capstan motor cannot perform both normal driving and high speed search driving. Therefore, the driving device using the high speed search is installed separately from the driving device for normal driving.

따라서 종래에는 릴구동장치가 전체적인 구조를 복잡하게 하고 원가상승을 초래하게 되는 문제점이 있었다.Therefore, in the related art, there is a problem that the reel driving device complicates the overall structure and causes a cost increase.

본 고안은 이러한 종래의 문제점을 해결하기 위하여 필을 캡스턴 모터로 구동되는 캠스턴 풀리에 연동시키면서도 정상주행 구동과 고속탐색 구동을 모터 실현할 수 있도록 함으로써 구조가 간단하게 되고 원가절감에 기여할 수 있도록 한 디지탈 오디오 테이프 레코더의 릴구동장치를 제공하려는 것이다.In order to solve the conventional problems, the present invention enables the motor to realize the normal driving and the high speed search driving while linking the fill to the camstan pulley driven by the capstan motor, thereby simplifying the structure and contributing to cost reduction. It is to provide a reel driving device of an audio tape recorder.

이하 본 고안은 첨부도면에 도시한 실시예에 따라서 상세히 설명한다.Hereinafter, the present invention will be described in detail according to the embodiment shown in the accompanying drawings.

The capstan shaft 14, the supply reel shaft 15, and the winding reel shaft 16 are respectively supported.

상기 공급릴축(15)에는 상기 캡스턴풀리(11)에 벨트(17)로 연동연결된 전동풀리(18)와, 전동기어(19)를 헛돌게 설치하여 클러치(20)로 접속한다.The supply reel shaft 15 is electrically connected to the capstan pulley 11 with the electric pulley 18 and the electric gear 19 interlocked by the belt 17, and is connected to the clutch 20 by loosening.

상기 베이스(10)에는 아이들러축(21)과, 기어축(22)을 설치하여 아이들러축(21)에는 상기 전동기어(19)에 맞물리는 입력기어(23)와 구동기어(24) 및 구동기어(24) 에 맞물리는 아이들러기어(25)가 설치된 아이들러암(26)을 헛돌게 설치하고 상기 입력기어(23)와 구동기어(24)의 세레이션형 보스부(23')(24')에는 변환기어(27)의 세레이션형축공(27')을 삽입하며, 기어축(22)에는 상기 변환기어(27)에 접탈되는 분기입력기어(28)와 상기 구동기어(24)에 맞물리는 분기구동기어(29)를 헛돌게 설치하여 클러치(30)로 접속한다.An idler shaft 21 and a gear shaft 22 are installed in the base 10, and an input gear 23, a drive gear 24, and a drive gear meshing with the electric gear 19 are installed on the idler shaft 21. The idler arm 26 provided with the idler gear 25 to be engaged with the 24 is installed in an undesired manner, and the serration-type boss portion 23 'and 24' of the input gear 23 and the drive gear 24 are provided. The serration shaft hole 27 'of the transducer gear 27 is inserted, and the gear shaft 22 has a branch which is engaged with the driving gear 24 and the branch input gear 28 attached to the transducer gear 27. The drive gear 29 is installed in a loose manner and connected to the clutch 30.

상기 전동풀리(18)와 전동기어(19)를 접속하는 클러치(20)는 펠트(31)와 캡(32) 및 스프링(33)으로 구성하며, 상기 분리입력기어(28)와 분기구동기어(29)를 접속하는 클러치(30)는 펠트(34)와 압력판(35) 및 스프링(36)으로 구성한다.The clutch 20 connecting the electric pulley 18 and the electric gear 19 is composed of a felt 31, a cap 32, and a spring 33, and the separation input gear 28 and the branch drive gear ( The clutch 30 which connects 29 consists of a felt 34, a pressure plate 35, and a spring 36.

상기 변환기어(27)의 세레이션형 축공(27')은 상기 입력기어(23)와 구동기어(24)의 세레이션형 보스부(23')(24')에 동시에 맞물리거나 입력기어(23)의 보스부(23')에만 맞물리는 상태로 승강되도록 구성한다.The serration shaft hole 27 'of the converter gear 27 meshes with the input gear 23 and the serration boss portion 23', 24 'of the drive gear 24 or input gear 23 at the same time. It is configured to move up and down in engagement with only the boss portion 23 '.

상기 아이들러기어(25)는 공급릴(12) 또는 권취릴(13)의 기어부(12')(13')에 선택적으로 맞물리도록 한다.The idler gear 25 is selectively engaged with the gears 12 'and 13' of the supply reel 12 or the take-up reel 13.

상기 아이들러기어(25)는 아이들러암(26)의 선단부에 펠트(27)와 캡축(38) 및 스프링(38)으로 된 클러치(40)으로 접속한다.The idler gear 25 is connected to the distal end of the idler arm 26 with a felt 27, a cap shaft 38, and a clutch 40 made of a spring 38.

이와같이 구성된 본 고안의 릴구동장치는, 캡스턴모터에 의하여 캡스턴풀리(11)가 회전하면, 벨트(17)에 의하여 전동풀리(18)에 전동되고, 여기서 클러치(20)를 통해 전동기어(19)에 전달되며, 다시 입력기어(23)에 전달되고 입력기어(23)의 보스부(23')와 변환기어(27)의 축공(27')에 의하여 변환기어(27)에 전달되며, 여기서 전달 계동이 각 모드별로 분리된다.When the capstan pulley 11 rotates by the capstan motor, the reel driving device of the present invention configured as described above is electrically driven by the belt 17 to the electric pulley 18, where the electric gear 19 is transmitted through the clutch 20. Is transmitted to the input gear 23 and to the converter gear 27 by the boss portion 23 'of the input gear 23 and the shaft hole 27' of the converter gear 27, where it is transmitted. The locking is separated for each mode.

즉, 변환기어(27)가 제2도와 같이 상부로 올라가서 그 축공(27')이 입력기어(23)와 구동기어(24)의 보스부(23')(24')와 동시에 맞물린 상태에서는 입력기어(23)의 회전력이 변환기어(27)를 통하여 구동기어(24)에 직접 전달되고, 구동기어(24)에 맞물린 아이들러기어(25)가 회전하면서 공급릴(12) 또는 권취릴(13)를 구동시키게 된다.That is, when the converter gear 27 is raised upward as shown in FIG. 2 and the shaft hole 27 'is engaged with the input gear 23 and the boss portions 23' and 24 'of the drive gear 24 at the same time, the input is performed. The rotational force of the gear 23 is transmitted directly to the drive gear 24 through the converter gear 27, and the feed reel 12 or winding reel 13 rotates while the idler gear 25 engaged with the drive gear 24 rotates. Will be driven.

한편, 변환기어(27)가 하부로 내려와서 그 축공(27')이 입력기어(23)의 보스부(23')에만 맞물린 상태에서는 분기입력기어(28)가 변환기어(27)에 맞물려서 회전되며 클러치(30)를 통해 분기구동기어(29)가 회전하게 되어 이에 맞물린 구동기(24)를 통해 아이들러 기어(25)가 회전되어 공급릴(12) 또는 권취릴(13)을 구동시키게 된다.On the other hand, when the converter gear 27 descends to the bottom and the shaft hole 27 'is engaged only with the boss portion 23' of the input gear 23, the branch input gear 28 is engaged with the converter gear 27 to rotate. The branch drive gear 29 is rotated through the clutch 30, and the idler gear 25 is rotated through the driver 24 engaged thereto to drive the supply reel 12 or the take-up reel 13.

여기서 변환기어(27)가 입력기어(23)와 구동기어(24)를 연결시킨 상태에서는 감속작용이 일어나지 않으므로 공급릴(12) 또는 권취릴(13)이 고속회전하게 되며, 변환기어(27)가 분기입력기어(28)에 맞물린 상태에서는 상기 변환기어(27)와 분기입력기어(28)간의 감속작용과 분기구동기어(29)와 구동기어(24)간의 감속작용으로 공급릴(12) 또는 권취릴(13)는 저속으로 회전하게 되는 것이다.Here, since the deceleration does not occur when the converter gear 27 connects the input gear 23 and the drive gear 24, the supply reel 12 or the take-up reel 13 rotates at a high speed, and the converter gear 27 Is engaged with the branch input gear 28, the supply reel 12 or the deceleration action between the transducer gear 27 and the branch input gear 28 and the deceleration action between the branch drive gear 29 and the drive gear 24. The winding reel 13 is to rotate at a low speed.

따라서, 재생, 녹음등 정상주행이 필요한 경우에는 변환기어(27)를 별도의 승강기구(도시되지 않음)로써 하강시켜 분기입력기어(28)에 접속시킴으로써 공급릴(12) 또는 권취릴(13)이 저속으로 회전하면서 테이프를 정상주행시키도록 하고, 고속 탐색시에는 변환기어(27)를 상승시켜 입력기어(23)과 구동기어(24)를 직접 연동연결시킴으로써 공급릴(12) 또는 권취릴(13)이 고속(정상주행의 200배속)으로 회전되면서 테이프를 고속주행시키도록 할 수 있는 것이다.Therefore, when normal driving such as reproduction or recording is necessary, the converter gear 27 is lowered by a separate lifting mechanism (not shown) and connected to the branch input gear 28 so that the supply reel 12 or the winding reel 13 is removed. The tape is allowed to run normally while rotating at a low speed, and during the high-speed search, the converter gear 27 is raised to directly connect the input gear 23 and the drive gear 24 to the feed reel 12 or the winding reel ( 13) can be rotated at a high speed (200 times normal driving speed) to drive the tape at high speed.

또한 상기 전동풀리(18)와 전동기어(19)및 분기입력기어(28)와 분기구동기어 (29)는 각각 클러치(20)(30)으로 접속되어 있어 전동토르크를 조정할 수 있는 것이다.The electric pulley 18, the electric gear 19, the branch input gear 28 and the branch drive gear 29 are connected to the clutches 20 and 30, respectively, so that the electric torque can be adjusted.

이상과 같이 본 고안에 의하면 별도의 모터를 포함한 고속탐색구동장치를 설치하지 않고서도 캡스턴모터로 구동되는 캡스턴풀리에 릴을 연동시켜 정상주행구동과 고속탐색구동을 행할 수 있도록 하였으므로 구조가 간단하고 원가를 절감할 수 있게 되는 것이다.As described above, according to the present invention, since the reel is connected to the capstan pulley driven by the capstan motor without the installation of the high speed search driving apparatus including a separate motor, the normal driving and the high speed search driving can be performed. It will be possible to save.
