본 발명은 브이시알(VCR)의 회전헤드드럼에 관한 것으로서 더욱 상세하게는 부품수를 줄여 조립작업성을 향상시킴과 함께 제작비도 절감시킬 수 있도록 한 것이다.The present invention relates to a rotating head drum of the VCR (VCR), more particularly, to reduce the number of parts to improve the assembly workability and to reduce the production cost.

종래 회전헤드드럼은 첨부도면 제 1 도에 도시된 바와 같이 하부드럼(1), 상기 하부드럼의 중심부에 회전가능하도록 베어링(2)(2a)에 의해 지지된 축(3), 상기 축의 상부에 압입고정된 플랜지(4), 상기 플랜지에 제 1 스크류(5)로 고정된 상부드럼(6), 상기 상부드럼의 하부면 일측에 제 2 스크류(7)로 고정된 회전헤드(8), 상기 하부드럼(1)내에 고정된 하부트랜스(9), 상기 플랜지(4)내에 고정되어 하부트랜스(9)와 신호를 주고받도록 된 상부트랜스(10), 상기 상부드럼(6)에 설치되어 상부트랜스(10)와 신호를 주고받도록 된 헤드터미널(11)과, 상기 하부드럼(1)의 저면에 제 3 스크류(12)로 고정된 모터스테이터(13), 상기 축(3)의 하단에 셋트스크류(14)로 고정된 링칼라(15), 상기 링칼라에 제 4 스크류(16)로 고정되어 모터스테이터(13)와의 자기력에 의해 축(3)을 회전시킬 수 있도록 된 모터로우터(17)로 구성되어 있다.Conventional rotating head drum is a lower drum (1), as shown in Figure 1 of the accompanying drawings, a shaft (3) supported by a bearing (2) (2a) to be rotatable in the center of the lower drum, the upper part of the shaft A press-fitted flange 4, an upper drum 6 fixed to the flange with a first screw 5, a rotating head 8 fixed with a second screw 7 on one side of the lower surface of the upper drum, A lower transformer 9 fixed in the lower drum 1, an upper transformer 10 fixed in the flange 4 to exchange signals with the lower transformer 9, and an upper transformer 6 installed in the upper drum 6; The head terminal 11 to exchange signals with the 10, the motor stator 13 fixed to the bottom of the lower drum 1 by the third screw 12, and a set screw at the lower end of the shaft 3 A ring collar 15 fixed with 14 and a fourth screw 16 fixed to the ring collar can rotate the shaft 3 by a magnetic force with the motor stator 13. It consists of a motor rotor 17.

상기 회전드럼을 전체적 구성으로 볼때 고정부는 하부드럼(1), 하부트랜스(9), 모터스테이터(13) 등으로 이루어져 있고 회전부는 베어링(2) (2a), 축(3), 플랜지(4), 상부드럼(6), 회전헤드(8), 상부트랜스(10), 헤드터미널(11), 링칼라(15), 모터로우터(17) 등으로 이루어져 있으며 구동시 회전부가 회전운동을 하면서 테이프에 기록된 정보를 재생하거나 테이프에 정보를 기록한다. 따라서, 테이프에 기록된 신호를 재생하거나 외부신호를 테이프에 기록하기 위해 전원을 인가하면 하부드럼(1)에 고정된 모터스테이터와 링칼라(15)에 고정된 모터로우터(17) 사이의 자기력에 의해 상기 모터로우터(17)가 회전하므로 축(3)이 베어링(2)(2a)의 구름운동을 받으며 회전하고 이에 따라 플랜지(4), 상부드럼(6), 회전헤드(8), 상부트랜스(10), 헤드터미널(11)이 회전하는데, 이때 하부드럼(1)내에 고정된 하부트랜스(9)와, 플랜지(4)내에 고정된 상부트랜스(10)의 채널간에 전자기적 상호작용이 일어나므로 선택된 신호에 따라 재생이 되거나 기록이 된다.In view of the rotating drum as a whole, the fixing part includes a lower drum (1), a lower transformer (9), a motor stator (13), and the like, and the rotating part includes a bearing (2) (2a), a shaft (3), and a flange (4). , Upper drum (6), rotating head (8), upper transformer (10), head terminal (11), ring collar (15), motor rotor (17), etc. Play the recorded information or record the information on tape. Therefore, when power is applied to reproduce the signal recorded on the tape or record the external signal on the tape, the magnetic force between the motor stator fixed to the lower drum 1 and the motor rotor 17 fixed to the ring collar 15 is applied. As the motor rotor 17 rotates, the shaft 3 rotates under the rolling motion of the bearings 2 and 2a, and thus the flange 4, the upper drum 6, the rotary head 8, and the upper transformer. (10), the head terminal 11 rotates, whereby electromagnetic interaction occurs between the channel of the lower transformer 9 fixed in the lower drum 1 and the upper transformer 10 fixed in the flange 4 Therefore, playback or recording is performed according to the selected signal.

즉, 재생신호가 주어졌다면 상부드럼(6)에 고정된 회전헤드(8)의 팁(8a)이 상기 상부드럼(6)을 감싼 상태로 주행하는 테이프에 접촉되므로 회전헤드(8)가 테이프에 기록된 정보를 읽어 이 신호를 헤드터미널(11)→ 상부트랜스(10)→하부트랜스(9)→메인기판(도시는 생략함)을 통해 메인회로로 전달하여 재생을 하고 녹화신호가 주어졌다면 메인회로로부터 유입된 신호를 메인기판→하부트랜스(9)→상부트랜스(10)→헤드터미널(1)을 통해 회전헤드(8)로 전달하여 상기 회전헤드가 테이프에 신호를 기록한다.In other words, if a reproduction signal is given, the tip 8a of the rotating head 8 fixed to the upper drum 6 is in contact with the tape running while wrapping the upper drum 6, so that the rotating head 8 is connected to the tape. The recorded information is read and transmitted to the main circuit through the head terminal 11 → the top transformer 10 → the bottom transformer 9 → the main board (not shown) for playback. The signal flowed from the circuit is transmitted to the rotating head 8 through the main board → the lower transformer 9 → the upper transformer 10 → the head terminal 1, and the rotating head records the signal on the tape.

상기에서 모터로우터(17)의 회전운동에 따라 축(3)이 회전하는 것은 상기 축의 하단에 링칼라(15)가 고정되어 있고 상기 링칼라에는 모어로우터(17)가 고정되어 있어 모터로우터의 회전력이 링칼라(15)를 통해 축(3)으로 전달되므로 가능하다.The rotation of the shaft 3 in accordance with the rotational motion of the motor rotor 17 is the ring collar 15 is fixed to the lower end of the shaft and the mower rotor 17 is fixed to the ring collar, the rotational force of the motor rotor This is possible since it is transmitted to the shaft 3 via the ring collar 15.

그러나 종래 이와 같은 회전헤드드럼은 회전헤드가 상부트랜스와는 떨어져 고정되어 있고, 상기 회전헤드와 상부트랜스는 헤드터미널에 의해 서로 연결되어 신호를 주고받을 수 있도록 되어 있으며, 상부드럼은 플랜지에 의해 축과 고정되어 있으므로 구조가 복잡하여 조립시 치수관리등에 신경을 써야하므로 작업성이 떨어짐은 물론 제작비도 상승되는 문제점이 있었다.However, in the conventional rotating head drum, the rotating head is fixed away from the upper transformer, and the rotating head and the upper transformer are connected to each other by a head terminal to transmit and receive signals, and the upper drum is connected to the shaft by a flange. Because it is fixed to and the structure is complicated, care must be taken in dimensional management when assembling, so there was a problem that the workability is lowered as well as the manufacturing cost is increased.

본 발명은 상기 문제점을 해결하기 위하여 안출한 것으로, 상부트랜스에 회전헤드를 일체화하고 상부드럼을 축에 직접 고정하여 구조를 간단하게 함에 따라 조립작업성이 향상되도록 함과 함께 제작비도 절감할 수 있도록 하는데 그 목적이 있다.The present invention has been made to solve the above problems, by integrating the rotating head to the upper transformer and directly fixing the upper drum to the shaft to simplify the structure to improve the assembly workability and to reduce the production cost Its purpose is to.

상기 목적을 달성하기 위한 본 발명 형태에 따르면, 축의 회전에 따라 함께 회전하는 상부드럼에 회전헤드가 일체화된 상부트랜스를 고정하여서 된 본 발명 브이시알의 회전헤드드럼이 제공된다.According to the aspect of the present invention for achieving the above object, there is provided a rotating head drum of the VSI of the present invention by fixing an upper transformer in which the rotating head is integrated with the upper drum rotating together with the rotation of the shaft.

이하, 본 발명을 일실시예로 도시한 첨부된 도면 제 2도 내지 제 3도를 참고로 하여 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to FIGS. 2 through 3 of the accompanying drawings.

첨부도면 제 2 도는 본 발명 회전헤드드럼을 나타낸 종단면도이고, 제 3도는 본 발명 회전헤드드럼의 요부를 나타낸 분해사시도로서, 본 발명의 구성중 기설명된 종래의 구성과 동일한 부분은 생략하고 다만 도면상에 종래와 동일부호로 표기하였음을 미리 밝혀둔다.2 is a longitudinal cross-sectional view showing a rotating head drum of the present invention, and FIG. 3 is an exploded perspective view showing the main parts of the rotating head drum of the present invention, and the same parts as those of the conventional structure described above are omitted. Note that in the drawings it is indicated by the same reference numerals as in the prior art.

이하 본 발명의 요부구성을 설명하면 상부드럼(6)을 축(3)의 상단에 직접 압입고정하고 상기 상부드럼(6)에는 회전헤드가 일체화된 상부트랜스(10)를 고정한다.Hereinafter, the main structure of the present invention will be described in which the upper drum 6 is directly press-fitted to the upper end of the shaft 3, and the upper drum 6 is fixed to the upper transformer 10 in which the rotating head is integrated.

상부드럼(6)에는 회전헤드(8a)의 위치와 대응하는 위치에 회전헤드(8a)가 위치하도록 개구부(6a)를 형성하여 상부트랜스(10)에 고정된 회전헤드가 상기 개구부(6a)에 위치되도록 한 후 상부트랜스(10)를 별도의 고정수단, 예를 들어 접착제 등으로 상부드럼의 내측 하면부에 직접 고정한다.An opening 6a is formed in the upper drum 6 so that the rotating head 8a is positioned at a position corresponding to the position of the rotating head 8a, so that the rotating head fixed to the upper transformer 10 is provided in the opening 6a. After positioning, the upper transformer 10 is directly fixed to an inner lower surface of the upper drum by a separate fixing means, for example, an adhesive.

이와 같이 구성된 본 발명 회전헤드드럼의 작용을 간략하게 설명하면 후술하는 바와 같다.The operation of the rotating head drum of the present invention configured as described above will be described below.

재생 및 자기기록시 전원을 인가하면 모터스테이터(13)와 모터로우터(17) 사이의 자기력에 의해 축(3)이 회전하므로 상기 축의 상단에 직접 압입고정된 상부드럼(6)이 회전하는데, 이때 상부드럼에 고정된 상부트랜스(10)에 일체화 되어 있는 회전헤드(8a)의 팁이 주행하는 테이프에 접촉되므로 선택된 신호에 따라 재생이 되거나 기록이 된다.When the regenerative and magnetic oxy-power are applied, the shaft 3 rotates by the magnetic force between the motor stator 13 and the motor rotor 17, so that the upper drum 6 directly press-fitted on the upper end of the shaft rotates. Since the tip of the rotating head 8a, which is integrated with the upper transformer 10 fixed to the upper drum, is in contact with the traveling tape, playback or recording is performed according to the selected signal.

이하 구체적인 작용은 기설명된 종래 작용설명을 참고하면 이해가능하리라 생각되어 생략하였다.Hereinafter, the specific operation will be omitted because it will be understood to refer to the conventional operation described above.

그러므로 본 발명은 회전헤드가 별도로 구비되지 않고 상부트랜스에 일체화되어 있으므로 종래 회전헤드와 상부트랜스를 연결하여 주는 헤드터미널이 필요없게 되고 축에 상부드럼이 직접 고정되어 있으므로 종래 상부드럼을 고정시켜 주기 위한 플랜지가 필요없게 되어 구조가 간단해짐에 따라 조립성이 향상됨과 함께 제작비도 절감되는 효과가 있다.Therefore, the present invention does not require a head terminal for connecting the rotary head and the upper transformer, because the rotary head is not provided separately and is integrated with the upper transformer, and the upper drum is directly fixed to the shaft to fix the conventional upper drum. By eliminating the need for flanges, the structure is simpler, which improves assembly and reduces manufacturing costs.
