본 고안은 자기기록재생기의 테이프 이완 보상장치에 관한 것으로, 브이씨알의 조그(jog), 셔틀(shuttle) 모드에서 역 슬로우(slow)시 테이프 텐션을 일정하게 유지하여 선명한 화면을 유지할 수 있도록 한 자기기록재생기의 테이프 이완 보상장치에 관한 것이다.The present invention relates to a tape relaxation compensation device of a magnetic recorder, and has a magnet to maintain a clear screen by maintaining a constant tape tension during reverse slow in jog or shuttle mode of V-Cal. A tape relaxation compensation device of a record player.

종래의 비디오 테이프 레코더는 제1도에 도시한 바와 같이, 베이스 플레이트에 공급릴(1)과 권취릴(2)이 설치되고, 공급릴(1)과 권취릴(2) 사이에 아이들러기구(3)가 설치되어 있다.In the conventional video tape recorder, as shown in FIG. 1, a feed reel 1 and a take-up reel 2 are provided on a base plate, and an idler mechanism 3 is provided between the feed reel 1 and a take-up reel 2. ) Is installed.

상기 아이들러기구(3)는 클러치 기어(4)와 축(3') 상단부에 결합되는 아이들 암(5)과 아이들 암(5)의 선단부에 축착되는 아이들러 기어(6)으로 구성되어 있다.The idler mechanism 3 is composed of an idler arm 5 coupled to the clutch gear 4 and an upper end of the shaft 3 'and an idler gear 6 that is affixed to the distal end of the idler arm 5.

또한, 모드 변환용 펑션 플레이트(function plate)(7)의 일측단부에는 작동홈(8)이 형성되고, 아이들러기구(3)의 일측에는 조그(jog)레버(9)가 축(10)으로 축착되어 있으며, 조그레버(9)의 일단부에 형성된 작동돌기(11)가 상기 펑션 플레이트(7)의 작동홈(8)에 삽입되고, 조그레버(9)의 타단부에 형성된 기어부(12)가 상기 아이들러 기구(3)의 클러치 기어(4) 상단부에 형성된 조그기어(13)에 맞물려 있다.In addition, an operation groove 8 is formed at one end of the function plate 7 for mode conversion, and a jog lever 9 is fixed to the shaft 10 on one side of the idler mechanism 3. The operation protrusion 11 formed at one end of the jog lever 9 is inserted into the operation groove 8 of the function plate 7, and the gear part 12 formed at the other end of the jog lever 9. Is engaged with the jog gear 13 formed at the upper end of the clutch gear 4 of the idler mechanism 3.

이러한 종래의 장치는 아이들러 기어(6)가 권취릴(2)에 붙어있는 상태에서 역 슬로우(slow)를 행하게 되면 펑션 플레이트(7)가 이동하여 조그레버(9)의 작동돌기(11)가 펑션 플레이트(7)의 작동홈(8)을 움직임에 따라 조그레버(9)가 회전하게 되며, 이 회전력으로 클러치 기어(4)가 회전하고, 아이들러 기어(6)가 회전하여 공급릴(1)를 회전시킴으로써 테이프를 감아주게 된다.In this conventional device, when the idler gear 6 is reversed while the idler gear 6 is attached to the take-up reel 2, the function plate 7 moves and the operation projection 11 of the jog lever 9 is functioned. As the operating groove 8 of the plate 7 moves, the jog lever 9 rotates. With this rotational force, the clutch gear 4 rotates, and the idler gear 6 rotates to feed the feed reel 1. The tape is wound by rotating it.

그러나, 상기한 바와 같은 종래의 테이프 이완 보상장치는 회전력을 상쇄시킬 수 없는 구조이므로 브이씨알의 조그(jog), 셔틀(shuttle) 모드에서 역 슬로우(slo) 시테이프 텐션이 증가하게 되며, 테이프 텐션이 일정하지 않아 화면에 노이즈가 생기게 될 뿐아니라, 테이프 텐션이 강하면 헤드에 이물질이 생기고 테이프에 손상이 생기는 결함이 있었다.However, the conventional tape relaxation compensator as described above does not cancel the rotational force, so the reverse slow tape tension is increased in jog and shuttle modes of V-Cal, and the tape tension is increased. This irregularity not only creates noise on the screen, but also a strong tape tension that results in foreign matter on the head and damage to the tape.

본 고안은 상기한 바와 같은 종래의 결함을 해소하기 위하여 창안한 것으로, 회전 구동력을 일정하게 전달하는 조그 클러치기어를 아이들러기구와 연결, 설치하고, 펑션 플레이트에 형성한 기어치로 조그 클러치기어를 구동하도록 한 것인 바, 이러한 본 고안을 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention was devised to solve the above-mentioned conventional defects, and connects and installs a jog clutch gear that constantly transmits rotational driving force with an idler mechanism, and drives the jog clutch gear with the gear teeth formed on the function plate. If it is described in detail by the accompanying drawings of the present invention as follows.

제3도 내지 제5도에 도시한 바와 같이, 아이들러기구(3)의 일측부에 그 아이들러기구(3)의 클러치 기어(4)와 연결되는 조그 클러치기어(20)가 설치되고, 상기 펑션 플레이트(7)에는 상기 조그 클러치기어(20)를 작동시키기 위한 기어치(30)가 형성된 구성이며 상기 조그 클러치기어(20)는 베이스 플레이트(B)에 고정한 축(21)에 입력기어(22)와 홀더(23)가 서로 압입된 상태로 삽입되고, 그들 사이에 출력기어(24)가 삽입되어 있으며, 입력기어(22)와 출력기어(24) 사이에 펠트(25)와 스프링(26)이 결합되고, 출력기어(24)와 홀더(23) 사이에 펠트(27)가 결합된 구성으로 되어 있다.3 to 5, a jog clutch gear 20 connected to the clutch gear 4 of the idler mechanism 3 is provided at one side of the idler mechanism 3, and the function plate is provided. (7) the gear teeth 30 for operating the jog clutch gear 20 is formed and the jog clutch gear 20 is the input gear 22 and the shaft 21 fixed to the base plate (B) The holders 23 are inserted into each other and the output gears 24 are inserted therebetween, and the felt 25 and the spring 26 are coupled between the input gear 22 and the output gear 24. The felt 27 is configured to couple between the output gear 24 and the holder 23.

이와 같은 본 고안의 테이프 이완 보상장치는 아이들러 기어(6)가 권취릴(2)에 붙어 있는 상태에서 역 슬로우(slow)를 행하게 되면 펑션 플레이트(7)가 이동하여 펑션 플레이트(7)의 기어치(30)가 조그 클러치기어(20)의 입력기어(22)를 회전하고, 입력기어(22)가 회전하면 스프링(26)의 힘으로 출력기어(24)에 회전 토크(torque)가 생겨 회전하게 되고, 권취릴(2)에 붙어 있는 아이들러 기어(6)를 공급릴(1)측으로 회전시켜 공급릴(1)에 테이프를 감아 주게 된다.The tape relaxation compensation device of the present invention has a function plate 7 that moves when the idler gear 6 is attached to the take-up reel 2, and the function plate 7 moves to the gear teeth of the function plate 7. 30 rotates the input gear 22 of the jog clutch gear 20, and when the input gear 22 rotates, a rotation torque is generated in the output gear 24 by the force of the spring 26 to rotate. Then, the idler gear 6 attached to the take-up reel 2 is rotated toward the supply reel 1 side, and the tape is wound around the supply reel 1.

그리고, 이러한 본 고안의 테이프 이완 보상장치는 조그 클러치기어(20)의 회전토크가 일정하므로 테이프를 적정한 힘으로 당기게 되며, 이에 따라 테이프의 텐션이 일정하게 유지되므로 화면의 노이즈를 방지하고 테이프의 손상을 방지할 수 있게 된다.In addition, the tape relaxation compensation device of the present invention pulls the tape with an appropriate force because the rotational torque of the jog clutch gear 20 is constant, and thus the tension of the tape is kept constant, thereby preventing noise on the screen and damaging the tape. Can be prevented.

이상에서 설명한 바와 같은 본 고안의 테이프 이완 보상장치는 조그(jog), 셔틀(shuttle) 모드에서 역 슬로우(slow)시 테이프 텐션을 일정하게 유지하여 선명한 화면을 유지할 수 있으며, 테이프의 손상을 방지하여 사용 수명을 향상하는 이점이 있다.The tape relaxation compensation device of the present invention as described above can maintain a clear screen by maintaining a constant tape tension during reverse slow in jog, shuttle mode, and prevents damage to the tape There is an advantage of improving the service life.
