Abstract

The signal of a magnetic head (8) is transmitted directly to a rotary transformer (14) through wire guide holes (13,13',13") of a bush (6) placed between upper and lower drums (11,1) so that the outer noise is prevented-without earthening the drum. Because the head (8) is fixed on the upper side of the bush, the accumulated tolerence is reduced only by adjusting a head skrew (16). A damper plate (18) and a damper rubber (19) are installed on the upper drum (11) to prevent the eccentric rotation of the drum.

본 발명은 테이프 레코더에 있어서 헤드드럼사에 노이즈가 유입되는 것을 방지하고 헤드와 드럼의 가공과 조립공수를 줄일 수 있도록 하며 각 부품의 정밀도를 보다 향상시킬수 있도록 한 테이프 레코더의 헤드드럼에 관한 것이다.The present invention relates to a head drum of a tape recorder which prevents noise from flowing into the head drum yarn in the tape recorder, reduces the number of heads and drums to be processed and assembled, and further improves the precision of each component.

종래의 헤드드럼을 보면, 헤드에서 부시에 부착되어 있는 로터리 트랜스까지 신호를 전달하기 위해 드럼 표면으로 와이어를 돌출시키고 기판을 통해 우회연결하므로서 노이즈가 용이하게 유입되어 화면상태를 불량하게 하는 요인이 되있으며, 또 헤드의 위치를 설정하기 위하여 상부드럼에 헤드를 부착하고 상부드럼을 조립할 때 축을 기준으로 가공된 부시상면에 조립토록 하고 있으나, 상부드럼 가공시 발생된 누적공차가 헤드의 정확한 위치 설정에 영향을 미치게 되는 문제점이 있었고, 헤드와 상부드럼, 부시를 조립하는 과정에서 헤드에 이물질이 끼거나, 타물체와 접촉하여 헤드가 불량하게 설치되는 문제점은 물론 작업 공수가 많이 들게되는 등의 문제점이 있었다.In the conventional head drum, noise is easily introduced by projecting a wire to the drum surface and making a detour connection through the substrate to transmit a signal from the head to the rotary transformer attached to the bush. In addition, in order to set the position of the head, the head is attached to the upper drum and the upper drum is assembled to the upper surface of the bush processed based on the axis. There was a problem that affects, such as foreign matter caught in the head during the assembly of the head, the upper drum, the bush, or the head is badly installed in contact with other objects, as well as a lot of labor. there was.

본 발명은 상기와 같은 제반 문제점을 감안하여 연출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned problems and described in detail with reference to the accompanying drawings.

먼저 도시된 제1도에 의하여 설명한다.First, it will be described with reference to FIG.

하부드럼(1)에 베어링(2)을 설치하고 하부드럼(1)의 상부에는 스테이터(3)를 설치하여 어셈블리(4)를 구성하며 상기 베어링(2)에는 드럼축(5)을 설치한다.The bearing 2 is installed on the lower drum 1, the stator 3 is installed on the upper part of the lower drum 1, and the assembly 4 is configured. The drum shaft 5 is installed on the bearing 2.

상기 하부드럼(1)의 상측에는 부시(6)를 설치하되 이 부시(6)는 도시된 제2도에서와 같이 중아에는 축 삽입공(7)을 형성하고 이의 양측에는 헤드(8)를 체결하기 위한 헤드체결 나사공(9),(9')과 헤드(8)단차를 조절하기 위한 헤드조절나사공(10),10')을 형성하며, 상기 축 삽입공(7)의 전, 후에는 상부드럼(11)과 체결하기 위한 체결나사공(12),(12')을 형성한다. 그리고 또한 상기 축 삽입공(7)의 양측과 후방에는 각각 로터리 트랜스의 와이어 가이드공(13),(13'),13＂)을 형성한다. 다시, 도시된 제1도에서 부시(6)의 하부에는 로터리 트랜스(14)를 설치하며 이는 상기의 하부드럼(1)상부에 위치하도록 한다.A bush 6 is installed on the upper side of the lower drum 1, and the bush 6 forms a shaft insertion hole 7 in the middle child and fastens the head 8 on both sides thereof, as shown in FIG. The head fastening screw holes 9, 9 'and the head adjusting screw holes 10, 10' for adjusting the level of the head 8, and before and after the shaft insertion hole 7, The fastening screw holes 12 and 12 'for fastening with the upper drum 11 are formed. Further, on both sides and the rear of the shaft insertion hole 7, wire guide holes 13, 13 ', 13' of the rotary transformer are formed, respectively. Again, the rotary transformer 14 is installed in the lower part of the bush 6 in FIG. 1, which is located above the lower drum 1 above.

상기, 부시(6)의 헤드체결 나사공(9),(9')에는 헤드(8)를 해드체결볼트(15)로써 체결고정하여 부시 어셈블리를 구성한다. 이 부시 어셈블리는 상기의 드럼 어셈블리(4)과 트랜스 갭(TRANS GAP)을 안정하게 유지시키면서 조립구성한다. 그런데, 상기에서 하부드럼 어셈블리(4)와 부시 어셈블리를 조립할 때 부시(6)의 상면을 가공기를 사용하여 조립중 발생되는 누적공차와 조립오차를 회전축인 드럼축(5)을 기준으로 제가공한다.In the head fastening screw holes 9 and 9 'of the bush 6, the head 8 is fastened to the head fastening bolt 15 to form a bush assembly. This bush assembly is assembled while maintaining the drum assembly 4 and the TRANS GAP in a stable manner. However, when assembling the lower drum assembly (4) and the bush assembly, the upper surface of the bush (6) is processed using a processing machine based on the drum shaft (5), which is the rotational axis, of the accumulated tolerance and the assembly error. .

이후, 헤드조절나사공(10),(10')에는 헤드스크류(16)를 설치하고, 이 상태에서 상기의 헤드(8)를 조정한 다음 이와 상기 로터리 트랜스(14)간에는 로터리 트렌스 와이어(도시하지 않았음)를 연결하되 이는 상기 부시(6)의 와이어 가이드공(13),(13'),(13＂)에 가이드되도록 한다.Then, the head screw 16 is installed in the head adjusting screw holes 10 and 10 ', and in this state, the head 8 is adjusted, and then a rotary transformer wire (not shown) between the rotary transformer 14 is provided. Not connected to the wire guide hole 13, 13 ′, and 13 의 of the bush 6.

이와같이 구성된 상태에서 상부드럼(11)을 드럼축(5)에 삽입설치하여 체결볼트(17)로 부시(6)에 체결조립하여, 상부드럼(11)에는 댐퍼한(18)과 댐퍼고무(19)를 볼트(20)로써 체결시하여서 구성된 것이다.In this configuration, the upper drum 11 is inserted into the drum shaft 5 to be fastened and assembled to the bush 6 with the fastening bolt 17, and the upper drum 11 is damped with the damper 18 and the damper rubber 19 ) Is configured by fastening with the bolt (20).

이상과 같이, 구성된 본 발명은 상,하부 드럼(11),(1)사이에 부시(6)를 설치하고 헤드(8)의 신호를 드럼내부에서 부시(6)의 와이어 가이드공(13),(13'),(13＂)을 통하여 로터리 트랜지(14)로 직접연결시킴에 따라 헤드드럼상에 외부노이즈가 유입되는 것을 방지할 수 있고, 더욱이 드럼 어셈블리 외측에 노이즈 제거를 위한 별도의 접지상태를 설치하지 않더라도, 상,하드럼(11),(1)사이에 설치된 부시(6)에 의하여 노이즈 제거효과를 증대시킬 수 있으며, 헤드(8)가 부시(6)상면에 직접 부착되고, 헤드스크류(16)의 조정에 의하여 누적 공차의 발생을 방지하고 드럼 어셈블리 각 부품의 정밀도를 향상시킬수 있다. 또한 댐퍼판(18)과, 댐퍼고무(19)를 설치함으로써 편심회동을 방지할 수 있고, 가공조립 공정의 단축으로 작업공수를 줄일 수 있는 특징을 지닌 것이다.As described above, according to the present invention, the bush 6 is installed between the upper and lower drums 11 and 1, and the signal of the head 8 is transmitted to the wire guide hole 13 of the bush 6 within the drum. Direct connection to the rotary transistor 14 through 13 'and 13' prevents the introduction of external noise on the head drum. Moreover, a separate ground for noise removal outside the drum assembly. Even if the state is not provided, the noise removal effect can be increased by the bush 6 provided between the upper and lower drums 11 and 1, and the head 8 is directly attached to the upper surface of the bush 6, By adjusting the headscrew 16, it is possible to prevent the occurrence of accumulated tolerances and to improve the accuracy of each part of the drum assembly. In addition, by installing the damper plate 18 and the damper rubber 19, it is possible to prevent the eccentric rotation, and to reduce the work maneuver by shortening the processing assembly process.
