이 고안은 테이프 레코더의 드럼에 관한 것으로서, 더욱 상세하게는 캠코더(Camcorder)나 비데오 테이프 레코더(VTR) 등에 사용되는 드럼구조에서 헤드와 로타리 트랜스사이의 연결구조를 개선한 테이프 레코더의 드럼에 관한 것이다.The present invention relates to a drum of a tape recorder, and more particularly, to a drum of a tape recorder in which a connection structure between a head and a rotary transformer is improved in a drum structure used for a camcorder or a video tape recorder (VTR). .

일반적으로, 비데오 테이프 레코더나 캠코더 등에 사용되는 헤드드럼은 덱크상에 설치되어 드럼모터의 구동에 의해 회전되면서 일정경로를 따라 주행하는 테이프에 신호를 기록하거나 혹은 기록된 신호를 재생하는 된다.In general, a head drum used in a video tape recorder or a camcorder is installed on a deck and rotated by driving of a drum motor to record a signal on a tape traveling along a predetermined path or to reproduce a recorded signal.

제 1 도에 나타낸 바와같이 종래의 드럼(10)은 상부 드럼(11)과 하부 드럼(12)으로 이루어지면, 상기 상,하부 드럼(11),(12)의 중앙에는 회전축(13)이 베어링914)에 지지되어 억지끼워맞춤되고, 이 상부 드럼(11)의 하측면에는 회로 기판(17)이 접착된 헤드(15)가 고정나사(16)에 의해 고정설치되어 있다.As shown in FIG. 1, when the conventional drum 10 includes an upper drum 11 and a lower drum 12, a rotating shaft 13 is bearing at the center of the upper and lower drums 11 and 12. The head 15 to which the circuit board 17 is bonded is fixed to the lower side of the upper drum 11 by the fixing screw 16.

또한, 상기 하부 드럼(12)의 상면에는 스테이터 트랜스(18)가 고정설치되고, 이 스테이터 트랜스(18)의 상측으로 회로기판(17)이 접착된 로타리 트랜스(19)가 미세한 틈새가 유지되게 장착되고, 상기 로타리 트랜스(19)의 일측면과 상부 드럼(11)의 끝단이 접착되며, 이 상부 드럼(11)과 로타리 트랜스(19)가 회전축(13)에 의해 회전된다.In addition, the stator transformer 18 is fixedly installed on the upper surface of the lower drum 12, and the rotary transformer 19 to which the circuit board 17 is bonded is mounted on the upper side of the stator transformer 18 so that a minute gap is maintained. One side of the rotary transformer 19 and an end of the upper drum 11 are bonded to each other, and the upper drum 11 and the rotary transformer 19 are rotated by the rotary shaft 13.

한편, 상부 드럼(11) 하측면에 설치된 헤드(15)와 로타리 트랜스(19)간의 신호가 전달되도록 헤드(15)와 로타리 트랜스(19)에 와이어(20)가 접속되며, 이 와이어(20)의 접지상태를 유지하기 위해 헤드(15)와 로타리 트랜스(19)에 접착된 회로기판(19)사이에 커넥터(21)가 장착된다.On the other hand, the wire 20 is connected to the head 15 and the rotary transformer 19 so that the signal between the head 15 and the rotary transformer 19 installed on the lower side of the upper drum 11 is transmitted, the wire 20 The connector 21 is mounted between the head 15 and the circuit board 19 attached to the rotary transformer 19 to maintain the ground state of the connector.

따라서, 상부 드럼(11)의 하측면에 설치된 헤드(15)가 테이프의 신호를 읽어 로타리 트랜스(19)로 신호를 보내고, 이 로타리 트랜스(19)는 하부 드럼(12)에 고정설치되어 있는 스테이터 트랜스(18)로 신호를 전달하게 된다.Therefore, the head 15 provided on the lower side of the upper drum 11 reads the signal of the tape and sends a signal to the rotary transformer 19, which is fixed to the lower drum 12. The signal is transmitted to the transformer 18.

그러나, 상기와 같이 헤드와 로타리 트랜스간의 신호를 전달하는 와이어의 접지 및 조립성을 위해 별도의 연결기구인 커넥터가 사용되고, 이 커넥터의 양측으로 밴딩(Bending)된 부분이 양측 회로기판에 접속될 때 그 접속부위가 금도금으로 접속되어 생산비용이 상승됨은 물론 접지상태의 신뢰성이 저하되는 문제점이 발생하였다.However, when a connector, which is a separate connecting mechanism, is used for grounding and assembling of a wire that transmits a signal between the head and the rotary transformer as described above, and a bending portion of both ends of the connector is connected to both circuit boards. The connection part is connected with gold plating, which raises the production cost and causes a problem that the reliability of the grounding state is lowered.

이 고안은 상기와 같은 문제점을 해결하기 이하여 안출된 것으로서, 이 고안의 목적은 캠코더나 비데오 테이프 레코더 등에 사용되는 드럼의 헤드와 로타리 트랜스를 접속부재에 의해 연결되어 생산비용을 절감하고, 조립공정이 간편해지며, 접속을 확실히 할 수 있는 테이프 레코더의 드럼을 제공하는데 있다.This invention has been devised to solve the above problems, and the object of this invention is to connect the drum head and rotary transformer used in the camcorder or video tape recorder by the connecting member to reduce the production cost, and the assembly process This simplifies and provides a drum of a tape recorder that can be securely connected.

상기와 같은 목적을 달성하기 위한 이 고안의 특징을 일정한 주행 경로를 따라 이송되는 테이프에 신호를 기록하거나 기록된 신호를 재생시키기 위한 테이프 레코더의 드럼에 있어서, 헤드에 접착된 회로기판과 로타리 트랜스사이에 설치되고 한쪽면에 관통구멍이 형성된 탄성을 가지는 접속부재와, 상기 회로기판을 사이에 두고 접속부재와 헤드를 고정붙임하는 고정붙임부재를 포함한 것에 있다.A feature of this invention for achieving the above object is that in a drum of a tape recorder for recording a signal on a tape conveyed along a certain travel path or for reproducing a recorded signal, between a circuit board bonded to a head and a rotary trans And a connecting member having elasticity having a through hole formed on one side thereof, and a fixing member for fixing the connecting member and the head with the circuit board interposed therebetween.

이하, 이 고안의 일실시예를 첨부도면에 의하여 상세하게 설명한다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.

제 2 도의 (a),(b)는 이 고안을 설명하기 위한 도면으로서, 상부 드럼(31)의 하측면에 회로기판(39)이 접착된 헤드(38)가 고정붙임부재(34)에 의해 고정설치되고, 하부 드럼(32)에 고정설치된 스테이터 트랜스(35)의 상면에는 미세한 틈새가 유지되게 로타리 트랜스(36)가 장착된다.(A) and (b) of FIG. 2 are diagrams for explaining the present invention. The head 38 having the circuit board 39 adhered to the lower side of the upper drum 31 is fixed by the fixing member 34.
