본 고안은 테이프레코오더의 구동장치에 관한 것으로 특히 빨리감기와 되감기 조작장치의 개량에 관한 것이다. 종래 이런 종류의 구동장치는 제3도 및 제4도에 도시한 바와같이, 모우터(M)측에 고정된 풀리(미도시)와 플라이휠(21) 및 구동풀리(22)에 고무벨트(23)를 걸고, 구동풀리(22)와 동축인 구동기어(24)를 일단에 스프링(25)가 설치된 요동레버(26)의 일단에 형성된 자유단부(27)에 회전가능하게 지지하고 빨리 감기레버(28)와 되감기레버(29)에 단층상캠면(28')(29')을 형성한 것이다.The present invention relates to a drive of a tape recorder, and more particularly to an improvement of an apparatus for fast forwarding and rewinding. Conventionally, this type of drive device has a rubber belt 23 on the pulley (not shown) and the flywheel 21 and the driving pulley 22 fixed to the motor M side as shown in FIGS. 3 and 4. ), The drive gear 24, which is coaxial with the drive pulley 22, is rotatably supported on the free end 27 formed at one end of the swing lever 26 having a spring 25 at one end thereof, and is fast-wound lever ( 28) and tomographic cam surfaces 28 'and 29' are formed on the rewind lever 29.
동작상태를 설명하면, 제4(a)도와 같이 빨리감기레버(28)의 압입하면 고무벨트(23)의 장력에 의해 요동레버(26)가 반시계방향으로 회동되면서 자유단부(27)의 돌기(27')는 캠면(28')의 홈부(28")에 위치하게 되고, 이때 구동기어(24)는 테이프 회전축(30)에 고정된 기어(30')에 항상 개합되어 있는 전달기어(31)와 계합되므로서 회전축(30)이 반시계방향으로 고속회전하여 빨리감기 동작을 행하게 된다.Referring to the operating state, as shown in FIG. 4 (a), when the fast-winding lever 28 is press-fitted, the swing lever 26 rotates counterclockwise by the tension of the rubber belt 23, and thus the projection of the free end 27 is rotated. 27 'is located in the groove 28 " of the cam face 28', wherein the drive gear 24 is always integrated with the gear 30 'fixed to the tape rotation shaft 30. ), The rotating shaft 30 rotates at a high speed counterclockwise to perform a fast forwarding operation.
되감기 동작시에는 제4(b)도와 같이 되감기레버(29)의 압입하면 레버(29)의 단부 걸림턱(29a)이 도동레버(26)의 스프링(25)을 밀어서 요동레버(26)를 시계방향으로 회동시키며, 자유단부(27)의 돌기(27")가 레버(29)의 캠면(29')의 홈부(29")에 위치하게 되고, 이때 구동기어(24)는 테이프 회전축(32)에 고정된 기어(32')와 계합되어 회전축(32)을 시계방향으로 고속회전시켜 되감기 동작을 행하게되는 것이다.During the rewind operation, when the rewind lever 29 is press-fitted as shown in FIG. 4 (b), the end engaging jaw 29a of the lever 29 pushes the spring 25 of the swing lever 26 to watch the swing lever 26 Direction, the projection 27 " of the free end 27 is located in the groove 29 " of the cam face 29 'of the lever 29, wherein the drive gear 24 is the tape rotation shaft 32. It is engaged with the gear 32 'fixed to the rotating shaft 32 to rotate the clockwise in a high speed to perform the rewinding operation.
따라서 종래에는 빨리감기 동작시 구동기어(24)와 전달기어(31)를 고무벨트(23)의 장력에 의해 계합시켰기 때문에 잠시간 사용시 고무벨트(23)가 경화되어 장력이 약화되므로 구동기어(24)와 전달기어(31)의 계합이 불안정한 상태로 되어 그 동작의 신뢰성이 열화되고 구동기어(24)와 달기어(31)의 마모가 심하게 되어 수명이 단축되는 등 많은 문제점이 있었다.Therefore, in the related art, since the drive gear 24 and the transmission gear 31 are engaged by the tension of the rubber belt 23 during the fast-forward operation, the rubber belt 23 is hardened when the time is used, and thus the tension is weakened. And the engagement of the transmission gear 31 is in an unstable state, the reliability of the operation is deteriorated, the wear of the drive gear 24 and the gear 31 is severe, there are many problems such as shortening the life.
본 고안은 이러한 종래의 제반문제점을 해결하기 위하여 안출된 것으로 이를 첨부도면에 따라서 상세히 설명 하면 다음과 같다.The present invention has been devised to solve these problems in the prior art and described in detail according to the accompanying drawings.
본 고안은 제1도 및 제2도에 도시한 바와같이, 모우터(1)와 플라이휠(미도시) 및 구동풀리(2)에 고무벨트(3)를 걸고, 구동풀리(2)와 동축인 구동기어(4)를 요동레버(5)에 회전가능하게 지지하여 빨리감기 레버(6)와 되감기레버(7)에 의해 구동기어(4)를 테이프 회전축(7)에 고정된 기어(9)에 상시계합된 전달기어(10)와 회전축(11)에 고정된 기어(12)에 선택적으로 계합시키는 통상의 테이프 레코오더의 구동장치에 있어서, 구동기어(4)를 인장스프링(14)에 의해 구동기어(4)가 회전축(11)에 고정된 기어(12)에 계합되는 방향으로 부세된 요동레버(5)에 회동가능하게 지지하고, 빨리감기레버(6)에는 요동레버(5)의 타단의 돌핀(5')을 압입하여 요동레버(5)를 회동시키는 판스프링(13)을 설치한 것을 특징으로하는 것이다. 도면에 있어서, (15)는 되감기레버(7)에 형성된 캠공으로서 요동레버(5)의 돌핀(5')이 종동하는 단층상 캠면(15')이 형성되어 있다. 미설명부호(16), (17), (18) 및(19)는 임시정지레버, 정지(Stop) 및 이젝트(EJECT)레버, 재생레버 및 녹음레버이다.The present invention, as shown in Figures 1 and 2, the rubber belt (3) is fastened to the motor (1) and the flywheel (not shown) and the drive pulley (2), coaxial with the drive pulley (2) The drive gear 4 is rotatably supported by the swing lever 5 so that the drive gear 4 is attached to the gear 9 fixed to the tape rotation shaft 7 by the fast forward lever 6 and the rewind lever 7. In the drive device of a conventional tape recorder which selectively engages a phase-matched transmission gear 10 and a gear 12 fixed to a rotating shaft 11, the drive gear 4 is driven by a tension spring 14. The gear 4 is rotatably supported by the swing lever 5 biased in the direction engaged with the gear 12 fixed to the rotating shaft 11, and the fast forward lever 6 has the other end of the swing lever 5. It is characterized in that the leaf spring (13) for pressing the dolphin (5 ') is installed to rotate the swing lever (5). In the figure, reference numeral 15 denotes a cam hole formed in the rewind lever 7, and a single-layer cam surface 15 'on which the dolphin 5' of the swing lever 5 is driven is formed. Reference numerals 16, 17, 18, and 19 are temporary stop levers, stop and eject levers, playback levers, and recording levers.
이러한 구성에 따른 본 고안의 작용 효과를 설명하면 다음과 같다. 빨리감기 동작시에는 제2(a)도와 같이 빨리감기레버(6)를 압입하면 레버(6)에 고정된 판스프링(13)이 요동레버(5)에 돌설된 단부돌핀(5')을 압입하게 되고 요동레버(5)가 스프링(14)의 인장력에 대항하여 시계방향으로 회동하여 요동레버(5)에 지지된 구동기어(4)는 전달기어(10)와 계합하게 된다.Referring to the effect of the present invention according to this configuration is as follows. In the fast-forwarding operation, as shown in FIG. 2 (a), when the fast-winding lever 6 is press-fitted, the leaf spring 13 fixed to the lever 6 press-fits the end dolphin 5 'protruding from the swinging lever 5. When the swing lever 5 rotates clockwise against the tension of the spring 14, the drive gear 4 supported by the swing lever 5 engages with the transmission gear 10.
이때 구동기어(4)는 동측인 구동풀리(2)가 고무벨트(3)에 의해 반시계방향으로 회전하는 모우터(1)에 연동되어 있으므로 반시계방향으로 회전하며, 전달기어(17)는 회전축(8)에 고정된 기어(9)에 상시계합되어 있으므로 회전축(8)은 반시계방향으로 고속회전하여 빨리감기 동작을 행하게 된다.At this time, the drive gear 4 is rotated counterclockwise because the drive pulley 2 on the east side is linked to the motor 1 rotating counterclockwise by the rubber belt 3, and the transmission gear 17 is Since it is clockwise coupled to the gear 9 fixed to the rotary shaft 8, the rotary shaft 8 rotates at a high speed in the counterclockwise direction to perform a fast forward operation.
되감기 동작시에는 제2(b)도와 같이, 되감기레버(7)를 압입하면, 요동레버(5)가 스프링(14)에 의해 반시계방향으로 회동되면서 단부돌핀(5')가 되감기레버(7)에 형성된 캠공(15)의 캠면(15')의 요홈부에 위치하게되고, 이때 구동기어(4)가 회전축(11)에 고정된 기어(12)에 계합하게 되므로 회전축(11)은 시계방향으로 고속회전하여 되감기 동작을 행하게 되는 것이다.During the rewind operation, when the rewind lever 7 is press-fitted as shown in FIG. ) Is located in the recess of the cam surface 15 ′ of the cam hole 15 formed in the cam hole 15. At this time, the driving gear 4 is engaged with the gear 12 fixed to the rotating shaft 11, so that the rotating shaft 11 is clockwise. It rotates at a high speed and rewinds.
이상과 같이 본 고안은 빨리감기 동작시 빨리감기 레버(6)에 고정된 판스프링(13)에 의해 요동레버(5)를 회동시켜 구동기어(4)를 전달기어(10)에 계합시키는 것이므로 종래 고무벨트를 이용하는 것에 비해 구동기어(4)와 전달기어(10)의 계합이 확실하게되고 판스프링(13)이 요동레버(5)의 단부돌핀(5')을 압압하는 힘이 반영구적으로 불변하므로 그 동작의 신뢰성이 높게되고 전동기어(4)와 전달기어(10)의 마모가 극소화되어 사용수명이 연장되는 효과가 있는 것이다.As described above, the present invention is to engage the driving gear 4 with the transmission gear 10 by rotating the swing lever 5 by the leaf spring 13 fixed to the fast forward lever 6 during the fast forward operation. Compared with the use of a rubber belt, the engagement between the drive gear 4 and the transmission gear 10 is secured, and the force that the leaf spring 13 presses the end dolphin 5 'of the swing lever 5 is semi-permanently unchanged. The reliability of the operation is high and the wear of the electric gear 4 and the transmission gear 10 is minimized, thereby extending the service life.
