본 고안은 카세트 테이프 레코더의 구동장치에 관한 것으로, 특히 FR기어를 FR홀더에 설치하여 FR기어와 FR홀더가 함께 이동되도록 하므로써 FR기어가 리일기어 및 FF기어에 정확하게 접속되도록 한 카세트 테이프 레코더의 구동장치에 관한 것이다.The present invention relates to a driving device of a cassette tape recorder. In particular, the FR gear is installed in the FR holder so that the FR gear and the FR holder are moved together so that the FR gear is connected to the rail gear and the FF gear accurately. Relates to a device.
카세트 테이프 레코더에는 플레이(PLAY)뿐만 아니라 빨리감기(FF) 및 되감기(REW)장치가 설치되어 있어 소비자들이 필요에 따라 편리하게 이용할 수 있도록 되어 있다.Cassette tape recorders are equipped with fast forward (FF) and rewind (REW) devices as well as PLAY, so that consumers can conveniently use them as needed.
그 중 빨리감기(FF)와 되감기(REW)를 행할 때, 종래에는 FR레버의 일단에 FR풀리와 일체로 형성된 FR기어가 한 개의 축을 중심으로 좌우 회동하여 빨기감기 및 되감기를 행하도록 함으로써 FR기어가 리일기어 또는 FF기어와 정확하게 맞물리지 않게 되고, 그에 따라 많은 소음 및 기어의 마모가 발생하여 카세트 테이프 레코더의 수명이 단축되는 문제점이 있었다.Among them, when performing fast forward (FF) and rewind (REW), conventionally, FR gear formed integrally with FR pulley at one end of FR lever rotates left and right about one axis to perform rewind and rewind. There is a problem that does not mesh correctly with the rail gear or the FF gear, thereby causing a lot of noise and wear of the gear to shorten the life of the cassette tape recorder.
이에 본 고안에서는 상기와 같은 종래의 문제점을 해결 하여 FR기어가 리일기어 또는 FF기어와 정확하게 맞물려 소음이 나지 않는 동시에 카세트 테이프 레코더의 수명이 연장될 수 있도록 걸림돌기와 절곡부를 갖춘 FR홀더에다 FR기어와 FR풀리를 설치하여 내측 테이프와 안내홈을 갖춘 FR레버에 의하여 상기 FR기어가 리일기어 및 FF기어에 탄성적으로 접속되도록 한 카세트 테이프 레코더의 구동장치를 제공하는데 그 목적이 있다.Therefore, the present invention solves the above-mentioned problems, and the FR gear is equipped with the FR gear and the FR holder with the engaging protrusion and the bent portion so that the life of the cassette tape recorder can be extended at the same time as the FR gear is accurately engaged with the reel gear or the FF gear. It is an object of the present invention to provide a cassette tape recorder driving apparatus in which the FR gear is elastically connected to the reel gear and the FF gear by installing an FR pulley and having an inner tape and an FR lever having a guide groove.
이하 본 고안의 구성 및 작용효과는 첨부된 예시도면에 의거 상세히 설명하면 다음과 같다.Hereinafter, the configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 메인샤시(1)와 FR홀더(2)사이에 설치되는 FR레버(3.3')의 한쪽부에다 외측 테이퍼부(4)와 안내홈(5) 및 걸림턱(6)을 형성하면서 이 안내홈(5)에 연해 내측 테이퍼부(7)와 걸림부(8)를 형성하는 한편, 상기 FR홀더(2)의 양쪽 끝단에는 걸림돌기(9.9') 및 절곡부(10)를 각각 형성하는 동시에 중간부에는 결합구멍(11)을 형성하여 FR기어(12)와 FR풀리(13)를 일체로 결합 설치하면서 상기 걸림돌기(9.9')와 절곡부(10)가 메인샤시(1)에 형성된 정방형홈(14)에 각각 끼워져 상기 FR레버(3)에 의하여 상기 FR홀더(2)가 탄성적으로 좌우 수평이동되도록 한 구조로 되어 있다.The present invention forms an outer tapered portion 4, a guide groove 5, and a locking jaw 6 at one side of the FR lever 3.3 'installed between the main chassis 1 and the FR holder 2. In the guide groove (5) to form the inner tapered portion 7 and the engaging portion 8, while at both ends of the FR holder (2) to form a locking projection (9.9 ') and the bent portion (10), respectively At the same time, the engaging projection 11 is formed in the middle portion so that the FR gear 12 and the FR pulley 13 are integrally installed and the locking projection 9.9 'and the bent portion 10 are formed in the main chassis 1. The FR holder 2 is fitted into the square grooves 14 so that the FR holder 2 is horizontally moved horizontally and elastically by the FR lever 3.
미설명 부호 15는 모우터, 16는 리일기어, 17은 기어 18은 스프링이다.Reference numeral 15 is a motor, 16 is a reel gear, 17 is a gear 18 is a spring.
상기와 같은 구조로 된 본 고안은 모우터(15)의 회전력을 전달받은 FR기어(12)가 리일기어(16) 및 FF기어(17)에 정확하게 접속되도록 된 장치로서, 이를 제4도에 도시된 바와 같이 FR레버(3.3')가 메인샤시(1)와 FR홀더(2)사이에 설치되는바, 상기 FR레버(3.3')의 한쪽부에는 외측테이퍼(4)를 형성하여 걸림돌기(9)를 밀어주도록 하였음 뿐만 아니라 안내홈(5)을 형성하여 상기 걸림돌기(9')가 수납되도록 하였으며, 상기 안내홈(5)의 외측에는 걸림턱(6)을 형성하여 바로옆에 설치된 FR레버(3')를 밀어주도록 하였다. 또한 FR홀더(2)에는 스프링(18)이 메인샤시(1)와 연결되어 있어 FR홀더(2)가 탄성적으로 작동되도록 하였다.The present invention having the structure as described above is an apparatus in which the FR gear 12, which has received the rotational force of the motor 15, is connected to the reel gear 16 and the FF gear 17 accurately, which is shown in FIG. As described above, the FR lever 3.3 'is installed between the main chassis 1 and the FR holder 2, and an outer taper 4 is formed on one side of the FR lever 3.3' so that the projections 9 ), As well as to form a guide groove (5) to accommodate the engaging projection (9 '), the outer side of the guide groove (5) to form a locking jaw (6) FR lever installed next to (3 ') was pushed. In addition, the FR holder 2 has a spring 18 connected to the main chassis 1 so that the FR holder 2 is elastically operated.
한편, 제1도는 본 고안에 따른 카세트 테이프 레코더의 구동장치가 정지상태일때의 작동상태도로서, 이는 FR홀더(2)의 걸림돌기(9)가 FR레버(3)의 외측테이퍼부(4)바로 위에 위치되어 있는 동시에 걸림돌기(9')가 FR레버(3')의 걸림돌기(8)앞에 위치되어 있으며, FR기어(12)가 리일기어(16)와 FF기어(17)사이에 위치되어 있는 것이다.On the other hand, Figure 1 is an operating state diagram when the drive device of the cassette tape recorder according to the present invention is in a stopped state, which means that the engaging projection 9 of the FR holder 2 is immediately outside the outer taper portion 4 of the FR lever 3. At the same time, the locking projection 9 'is positioned in front of the locking projection 8 of the FR lever 3', and the FR gear 12 is located between the rail gear 16 and the FF gear 17. It is.
또한, 제2도는 빨리감기시의 작동상태를 나타낸 것으로 FR레버(3')가 전진하게 되면 FR홀더(2)가 스프링(18)의 힘으로 RR레버(3')의 안내홈(5)안으로 들어가게 되어 FR홀더(2)에 설치된 FR기어(12)가 FF기어(17)와 접촉되면서 빨리감기 동작이 수행된다.Also, FIG. 2 shows the operating state at the time of fast forwarding. When the FR lever 3 'is advanced, the FR holder 2 moves into the guide groove 5 of the RR lever 3' by the force of the spring 18. Since the FR gear 12 installed in the FR holder 2 is in contact with the FF gear 17, a fast forward operation is performed.
또한, 제3도는 되감기시의 작동상태를 나타낸 것으로, FR 레버(3)가 전진하게 되면 FR홀더(2)의 걸림돌기(9)가 FR레버(3)의 외측 테이퍼부(4)를 타고 좌측으로 수평이동하게 되어 FR 홀더(2)에 설치된 FR기어(12)가 리일기어(16)와 접속되면서 되감기동작이 수행된다.3 shows the operating state at the time of rewinding. When the FR lever 3 is moved forward, the engaging protrusion 9 of the FR holder 2 rides on the outer tapered portion 4 of the FR lever 3 to the left. It is horizontally moved, and the rewinding operation is performed while the FR gear 12 installed in the FR holder 2 is connected to the reel gear 16.
한편, 빨기감기 상태에서 정지상태에서 정지상태로 원위치될 경우를 설명하면, 제2도의 상태에서 정지레버(도시되지 않음)를 누르면 FR레버(3')가 후진하면서 FR홀더(2)의 걸림돌기(9')가 FR레버(3')의 내측 테이퍼부(7)를 타고 미끄러지면서 FR홀더(2)가 좌측으로 이동하게 되는바, 즉 우측으로 당기는 스프링(18)의 힘은 FR레버(3')가 후진하면 FR홀더(2)의 걸림돌기(9')가 FR레버(3')의 테이퍼부(7)를 타고 좌측으로 이동하게 되므로써 제1도의 상태가 되는 것이다.On the other hand, when the home position from the stop state to the stop state in the state of the cold winding state, when pressing the stop lever (not shown) in the state of FIG. 2, the FR lever (3 ') is reversed while the locking projection of the FR holder 2 As the 9 'slides on the inner tapered portion 7 of the FR lever 3', the FR holder 2 moves to the left, i.e., the force of the spring 18 pulling to the right is the FR lever 3 When ') is reversed, the locking projection 9' of the FR holder 2 is moved to the left by the taper portion 7 of the FR lever 3 ', and thus the state of FIG.
또한, 되감기상태에서 정지상태로 원위치될 경우를 설명하면, 제3도의 상태에서 정지레버(도시되지 않음)를 누르면, FR레버(3)가 후진하면서 FR홀더(2)는 스프링(18)의 힘에 의해 우측으로 이동되어 FR홀더(2)의 걸림돌기(9')가 FR 레버(3')의 걸림부(8)에서 멈춰지므로써 제1도의 상태가 되는 것이다.In addition, when the home position is returned to the stationary state from the rewinding state, when the stop lever (not shown) is pressed in the state of FIG. 3, the FR lever 2 moves backward while the FR holder 2 is driven by the spring 18. It is moved to the right side, and the locking projection 9 'of the FR holder 2 is stopped at the locking portion 8 of the FR lever 3'.
이와 같은 본 고안은 빨리감기 및 되감기시 FR기어(12)가 리일기어(6) 및 FF기어(17)와 정확하게 맞물려지므로써 정확하게 동작이 아루어질 뿐만 아니라 소음이 나지않는 동시에 카세트 테이프 레코더의 수명이 길어지는 효과가 있다.The present invention is such that the FR gear 12 is accurately engaged with the reel gear 6 and the FF gear 17 during fast forwarding and rewinding, so that the operation of the cassette tape recorder is not only performed accurately but also no noise is generated. It has a longer effect.
