Adhesives 15 and 15a are applied to the annular grooves 2b and 2c formed in the circumferential direction so that the channels A and B coils 5 and 7 are fixed to the adhesives 15 and 15a accordingly. Ends of the coils 5, 6, 7 and 8 are drawn out through guide grooves 2e and 2d formed at one side of the core 2a, and land portions 10 of the printed circuit board 9 are formed separately. It is a structure to be soldered and fixed to).

이와같이 구성된 종래 브이씨알의 헤드드럼은 제1도에 도시한 바와같이, 회전드럼(3)에 장착되어 있는 기록/재생헤드(13)(14)가 테이프의 재생신호를 읽어들여 회전트랜스(1)의 체널A, B코일(5)(7)에 인가하면, 회전트랜스(1)는 회전드럼(3)과 일체가 되어 회전하고 고정트랜스(2)는 고정드럼(4)가 일체가 되어 고정되어 있으므로 상기 기록/재생헤드(13)(14)에서 출력되는 재생신호가 회전트랜스(1)의 체널A, B코일(5)(7)을 통해 이와 대응되게 고정트랜스(2)의 환형홈(2b)(2c)에 접착제(15)(15a)로 접착고정된 채널A, B코일(6)(8)에 유기되고, 상기 채널 A, B코일(6)(8)에 유기된 재생신호는 제2도 내지 제5도에 도시된 바와같이 인쇄회로기판(9)의 랜드부(10) 및 패턴(12)을 통한후 접속부(11)와 접속된 외부 증폭기에서 소정레벨로 증폭되어 원하는 신호로 재생을 하게 된다.As shown in FIG. 1, the head drum of the conventional V-Cal configured as described above is rotated by the recording / reproducing head 13, 14 mounted on the rotating drum 3, reading the playback signal of the tape. When applied to the channel A and B coils 5 and 7 of the rotary transformer 1, the rotary transformer 1 is integrally rotated with the rotary drum 3 and the fixed transformer 2 is fixed as the fixed drum 4 is integrally fixed. Therefore, the annular groove 2b of the fixed transformer 2 corresponds to the reproduction signal output from the recording / reproducing heads 13 and 14 through the channel A and B coils 5 and 7 of the rotary transformer 1. (2c) to the channel A and B coils (6) and (8) fixed to the adhesive (15, 15a), and the reproduction signal is induced to the channel A, B coils (6) and (8) As shown in FIG. 2 to FIG. 5, through the land portion 10 and the pattern 12 of the printed circuit board 9, the amplifier is amplified to a predetermined level by an external amplifier connected to the connecting portion 11 to reproduce the desired signal.

그러나, 이와같은 종래 브이씨알 및 디에이티등의 헤드드럼에 있어서, 회전트랜스 및 고정트랜스를 만들기 위하여 채널A, B코일을 그 회전트랜스 및 고정트랜스의 코어에 형성된 환형홈에 감압하여 접착제로 접착고정을 하고 다시 인쇄배선기판에 납땜연결을 하므로서 코일이 서로 엉켜 취급성이 좋지않고, 또한 인쇄배선기판의 랜드부에 여러가닥의 코일을 일일이 납땜하여 연결을 하므로 조립의 불편성 및 생산성이 저하되고, 코일직경의 한계로 인하여 다채널화 하는데 문제점이 있을뿐 아니라 다채널화에 따른 코일의 수가 증가되는 문제점이 있었다.However, in such conventional head drums of BC-AL and DT, channel A and B coils are decompressed to the annular grooves formed in the core of the rotary transformer and the fixed transformer in order to make the rotary transformer and the fixed transformer. After soldering to the printed wiring board again, the coils are entangled with each other and the handleability is not good. Also, the soldering of several strands of the coils to the land portion of the printed wiring board is connected one by one, resulting in inconvenience in assembly and productivity. Due to the limitation of the coil diameter, there is a problem in that the number of coils increases due to the multi-channelization as well as the problem of the multi-channelization.

The purpose is to improve the assemblability, productivity, and handleability by doubling, and to realize multi-channelization. Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

As shown in (b), the through-hole 9 of the channel A annular substrate 1a is printed and drawn out through the lower surface, and the other side of the pattern 5 is printed through the through hole 10 in the circumferential direction of the center surface. After printing through the through hole 11 formed downward, the bottom surface of the channel A annular substrate 1a is printed and then connected to the connection portion 3a of the connecting substrate 3.

이와같이 구성된 본 고안의 작용, 효과를 제7도 내지 제11도에 의거 상세히 설명하면 다음과 같다.The operation and effects of the present invention configured as described above will be described in detail with reference to FIGS. 7 to 11.

회전드럼에 장착되어 있는 기록/재생헤드가 테이프의 재생신호를 읽어들여 회전트랜스의 코어에 접착되어 회전하는 인쇄회로기판의 패턴에 인가시키면 회전트랜스는 회전드럼과 일체가 되어 회전하고, 이와 대응되는 고정트랜스(2)는 고정드럼과 일체가 되어 회전하고, 이와대응되는 고정트랜스(2)의 코어(2a)에 형성된 채널A, B환형홈(2b)(2c)에 인쇄회로기판(1)의 채널A, B환형기판(1a)(1b)이 접착제(8)(8a)로 접착형합되어 있으므로 그 채널A, B환형기판(1a)(1b)의 상면에 원주방향으로 인쇄되어 있는 패턴(4)(5)으로 유기된다.When the recording / reproducing head mounted on the rotating drum reads the playing signal of the tape and applies it to the pattern of the rotating printed circuit board which is attached to the core of the rotating transformer, the rotating transformer rotates as one unit with the rotating drum. The fixed transformer 2 is integrally rotated with the fixed drum and rotates in the channel A and B annular grooves 2b and 2c formed in the core 2a of the fixed transformer 2 corresponding thereto. Since the channel A and B annular substrates 1a and 1b are adhesively bonded with the adhesives 8 and 8a, the pattern 4 printed in the circumferential direction on the upper surfaces of the channel A and B annular substrates 1a and 1b. It is organic to (5).

상기 패턴(4)(5)으로 유기된 재생신호는 제9도 및 제10도에 도시된 바와같이 상면의 패턴(4)(5)이 채널A, B환형기판(1a)(1b)의 스루홀(6)(7)을 통해 하면으로 인출되어 인쇄되고 다시 접속기판(3)을 통해 접속부(3a)에 연결된 관계로 인하여 회전트랜스의 인쇄회로기판으로 부터 유기된 재생신호가 상기 접속부를 통해 외부의 증폭기에서 소정레벨로 증폭되어 원하는 신호로 재생을 하게된다.As shown in FIGS. 9 and 10, the reproduced signal induced by the patterns 4 and 5 has the upper surface patterns 4 and 5 through the channel A and B annular substrates 1a and 1b. Due to the relationship drawn out through the holes 6 and 7 to the lower surface and then connected to the connecting portion 3a through the connecting substrate 3, the reproduction signal derived from the printed circuit board of the rotary transformer is externally supplied through the connecting portion. The amplifier is amplified to a predetermined level and reproduced with a desired signal.

또한 제12도와 같이 인쇄회로기판(1)의 채널A, B환형기판(1a)(1b)에 패턴(5)을 다층으로 인쇄할 경우에는 인쇄회로기판(1)넓이가 더욱 축소되어 다채널화에 유리한 잇점이 있다.In addition, when the pattern 5 is printed in multiple layers on the channel A and B annular substrates 1a and 1b of the printed circuit board 1 as shown in FIG. 12, the width of the printed circuit board 1 is further reduced to multi-channel. There is an advantage to this.

이상에서 상세히 설명한 바와같이, 본 고안은 헤드드럼에 장착된 회전 및 고정트랜스의 코일대신 다층으로 패턴을 코일일체형 박막형 플렉시블 인쇄회로기판을 사용 헤드드럼의 회전트랜스 및 고정트랜스의 코어에 접착제로 접착형합 하므로서 조립성, 생산성 및 취급성이 배가로 향상될뿐 아니라 패턴을 사용하므로 코일보다 치수면에서 유리하여 다채널화가 가능하고 부품수가 간소화되는 효과가 있다.As described in detail above, the present invention uses a coil-integrated thin-film flexible printed circuit board in a multi-layer instead of a coil of a rotating and fixed transformer mounted on the head drum, and adhesively bonds to the core of the rotating and fixed transformer of the head drum. As a result, assembling, productivity, and handling properties are not only doubled, but also patterns are advantageous in terms of dimensions than coils, thereby enabling multi-channelization and simplifying the number of parts.
