본 고안은 카셋트 테이프레코더의 릴 어셈블리 지지장치에 관한 것으로, 특히 메인샤시의 릴스탠드구멍 외주에다 테이퍼부를 갖춘 요철부를 형성시켜 릴스탠드가 보다 확실하고 용이하게 결합되도록 한 카셋트 테이프 레코더의 릴 어셈블리 지지장치에 관한 것이다.The present invention relates to a reel assembly support device for a cassette tape recorder, and in particular, a reel assembly support device for a cassette tape recorder in which an uneven portion having a tapered portion is formed on the outer periphery of the reel stand hole of the main chassis so that the reel stand is more reliably and easily coupled. It is about.
음향을 자기테이프에 기록, 재생시켜주는 장치인 카셋트 테이프 레코더에는 릴 어셈블리가 설치되어 테이프를 감아주거나 풀어줄 수 있도록 되어있는데, 종래에는 이를 카셋트 테이프레코더의 메인샤시에 구멍을 뚫어 릴축을 다른 물체에 압입시킨 것을 메인샤시에 리벳팅을 한다음 상기 릴축에다 릴기어와 릴드라이버를 조립하도록 되어 고정된 릴축을 중심으로 릴기어와 릴드라이버가 회전하게 되어 있었기 때문에 릴축의 표면조도(粗度)와 수직도등에 많은 문제가 발생하였을 뿐만 아니라 작업공정이 복잡하여 조립시간도 길어지게 된다는 여러 결점이 있었다.The cassette tape recorder, a device for recording and reproducing sound on magnetic tape, has a reel assembly installed so that the tape can be wound or unwound. After the riveting is done on the main chassis, the reel gear and the reel driver are assembled to the reel shaft. As the reel gear and the reel driver rotate about the fixed reel shaft, the surface roughness and verticality of the reel shaft are reduced. Not only did many problems occur on the back, but the work process was complicated, resulting in a long assembly time.
이에 본 고안에서는 상기와 같은 종래의 문제점을 해결하여 릴축의 가공비를 절약할 수 있을 뿐만 아니라 조립이 간단해질 수 있도록 메인샤시에다 2개의 릴스탠드구멍을 형성시키는 한편 릴스탠드구멍의 외주연에는 테이퍼부를 갖춘 요철부를 형성시켜 상홀더와 하홀더를 갖춘 릴스탠드를 결합시켜 설치하고, 릴스탠드의 상부와 하부에는 릴드라이버와 릴기어를 각각 접속시켜 릴축으로 삽입 결합시켜서된 카셋트 테이프 레코더의 릴 어셈블리 지지장치를 제공하는데 그 목적이 있다.Accordingly, the present invention solves the above-mentioned problems and saves the processing cost of the reel shaft, and forms two reel stand holes in the main chassis so that the assembly can be simplified, while the tapered portion is formed at the outer periphery of the reel stand holes. Reel assembly support device for cassette tape recorder formed by connecting the reel stand with upper holder and lower holder by forming the uneven part provided, and connecting the reel driver and the reel gear to the upper and lower parts of the reel stand, respectively, and inserting the reel shaft. The purpose is to provide.
이하 본 고안의 구성 및 작용효과를 첨부된 예시도면에 의거 상세히 설명하면 다음과 같다.Hereinafter will be described in detail based on the accompanying drawings and the configuration and effect of the present invention.
본 고안은 메인샤시(1)에 2개의 릴스탠드구멍(11)을 형성시키되 릴스탠드구멍(11)의 외주연에는 요부(13)와 테이퍼부(12)를 갖춘 철부(14)를 형성시켜 릴스탠드(12)를 결합하여 설치시키는 한편, 상기 릴스탠드(2)에는 상홀더(3)와 하홀더(4)를 형성시킴과 더불어 릴축(7)을 삽입하여 결합시키며, 릴스탠드(2)의 상부와 하부에는 릴드라이버(5)와 릴기어(6)를 각각 결합시킨 구조로 되어 있다.According to the present invention, two reel stand holes 11 are formed in the main chassis 1, and a reel portion 14 having a recess 13 and a tapered part 12 is formed at the outer circumference of the reel stand hole 11. While the stand 12 is coupled and installed, an upper holder 3 and a lower holder 4 are formed in the reel stand 2, and a reel shaft 7 is inserted and coupled to each other. The upper and lower portions have a structure in which the reel driver 5 and the reel gear 6 are respectively coupled.
상기와 같은 구조로 된 본 고안은 제 2 도에 도시된 바와 같이 메인샤시(1)에 형성시킨 릴스탠드구멍(11)의 외주연에 요철부(13)(14)를 형성하여 릴스탠드(2)의 상홀더(3)와 하홀더(4)가 결합되도록 하였는데, 상기 요철부(13)(14)에는 테이퍼부(12)를 형성시켜 릴스탠드(2)의 상홀더(3)와 하홀더(4)가 상기 테이퍼부(12)를 따라 활주운동을 하도록 하였다.The present invention having the structure as described above has the uneven parts 13 and 14 formed on the outer circumference of the reel stand hole 11 formed in the main chassis 1 as shown in FIG. The upper holder (3) and the lower holder (4) of the () is to be coupled, but the tapered portion (12) is formed in the uneven portion (13, 14), the upper holder (3) and the lower holder of the reel stand (2) (4) was to slide along the tapered portion (12).
이를 제 5 도와 제 6 도에 의거 좀더 상세히 설명하면 다음과 같다.This will be described in detail with reference to FIGS. 5 and 6 as follows.
메인샤시(1)의 후방에서 릴스탠드구멍(11)의 외주연에 형성된 3개의 요홈(15)내로 릴스탠드(2)의 상홀더(3) 3개를 삽입 결합시키면 제 5 도에 도시된 상태와 같이 상홀더(3)가 메인샤시(1) 윗면에 올라오게 되고 3개의 하홀더(4)는 메인샤시(1)의 아랫쪽에 점선과 같이 위치하게 된다. 이 상태에서 릴스탠드(2)를 60°정도 회전시키게 되면 릴스탠드(2)의 상홀더(3)는 제 4 도에 도시된 바와 같이 철부(14)의 테이퍼부(12)를 타고 올라가면서 요부(13)에 고정결합되어지도록 된 것이며, 이때 상기 요부(13)는 메인샤시(1)의 높이와 같은 높이로 형성시켜 요철부(13)(14)가 테이퍼부(12)를 갖추도록 함으로써 보다 확고하게 릴스탠드(2)가 메인샤시(1)에 고정되도록 한 것이다.When the three upper holders 3 of the reel stand 2 are inserted into the three recesses 15 formed at the outer circumference of the reel stand hole 11 at the rear of the main chassis 1, the state shown in FIG. The upper holder 3 is raised on the upper surface of the main chassis 1, and the three lower holders 4 are positioned like the dotted lines on the lower side of the main chassis 1. In this state, when the reel stand 2 is rotated about 60 degrees, the upper holder 3 of the reel stand 2 moves up the tapered portion 12 of the convex portion 14, as shown in FIG. It is to be fixed to the (13), wherein the recess 13 is formed to the same height as the height of the main chassis 1 so that the uneven portion 13, 14 has a tapered portion 12 The reel stand 2 is firmly fixed to the main chassis 1.
한편, 상기와 같이 메인샤시(1)의 릴스탠드구멍(11)에 릴스탠드(2)가 확고하게 결합되면 릴스탠드(2)의 상부에 릴드라이버(5)를 결합함과 동시에 릴스탠드(2)의 하부에 릴기어(6)를 접속시키는데, 상기 릴드라이버(5)와 릴스탠드(2) 및 릴기어(6)에는 릴축(7)이 결합되어 있으며, 특히 릴드라이버(5)와 릴기어(6)는 강제 압입되어 있으며, 릴기어(6)의 후방인 릴축(7)하단에는 스프링(8)과 링(9)을 끼워 와셔(10)로 결합 고정시켰는데, 이는 카셋트테이프를 카셋트테이프레코더에 장착할때 릴드라이버(5)가 완충작용을 할 수 있도록 한 것이다.On the other hand, when the reel stand 2 is firmly coupled to the reel stand hole 11 of the main chassis 1 as described above, the reel stand 2 is coupled to the upper part of the reel stand 2 at the same time. Reel gear (6) is connected to the lower part of the reel, the reel driver (5), the reel stand (2) and the reel gear (6), the reel shaft (7) is coupled, in particular the reel driver (5) and reel gear (6) is press-fitted, and the spring (8) and the ring (9) are fitted to the lower end of the reel shaft (7), which is the rear of the reel gear (6), to secure the cassette tape by cassette tape. When the reel driver 5 is mounted on the recorder, the buffering function is made.
여기서 릴드라이버(5)의 구동에 대하여 제 3 도에 의거 상세히 설명하면, 모우터의 회전력을 전달받는 중간기어(도면에 도시되어 있지 않음)는 상기 릴기어(6)와 접속되어 있어, 모우터에서 나오는 회전력은 중간기어가 전달받고, 그 중간기어의 회전력을 상기 릴기어(6)가 전달받게 되는데, 상기 릴기어(6)는 릴축(7)에 억지맞춤으로 끼워져 있기 때문에 릴기어(6)와 같이 회전하게 되며, 그에 따라 릴축(7)의 일단에 압입되어 있는 릴드라이버(5)를 회전시켜 주게되고, 릴드라이버(5)는 카셋트 테이프의 허브를 회전시켜 테이프를 감거나 풀어줄 수 있게 된 것이다. 이때 릴스탠드(2)는 메인샤시(1)에 조립되어 릴드라이버(6)가 흔들리지 않고 회전만할 수 있도록 하는 받침대 역할을 한다.Here, the driving of the reel driver 5 will be described in detail with reference to FIG. 3. An intermediate gear (not shown in the drawing), which receives the rotational force of the motor, is connected to the reel gear 6 and the motor The rotating force from the intermediate gear is transmitted, and the reel gear 6 receives the rotational force of the intermediate gear, and the reel gear 6 is fitted to the reel shaft 7 by force. It rotates as follows, accordingly to rotate the reel driver (5) is pressed into one end of the reel shaft (7), the reel driver (5) is able to wind or unwind the tape by rotating the hub of the cassette tape will be. At this time, the reel stand 2 is assembled to the main chassis 1 serves as a pedestal so that the reel driver 6 can only rotate without shaking.
이와 같은 본 고안은 종래 릴축(7)을 메인샤시(1)에 고정시키는 방법에 비하여 릴축(7)의 높은 정도의 표면조도가 요구되지 않으므로 릴축(7)의 가공비를 절약할 수 있는 동시에 수직도 유지에 유리하며, 리벳팅하는 시간을 절약할 수 있을 뿐만 아니라 부품의 수를 절약할 수 있어 제품의 소형화를 이룰 수 있는 효과가 있다.The present invention does not require a high degree of surface roughness of the reel shaft (7) compared to the conventional method of fixing the reel shaft (7) to the main chassis (1) can reduce the processing cost of the reel shaft (7) at the same time vertical It is advantageous for the maintenance and saves the time of riveting, and also the number of parts can be saved, which makes it possible to reduce the size of the product.
