본 고안은 테이프 레코더에 있어서, 헤드드럼의 회전을 안정화시키고 헤드드럼 어셈블리를 간소화할수 있도록한 테이프 레코더의 헤드드럼 장치에 관한 것이다.The present invention relates to a head recorder of a tape recorder in the tape recorder, which stabilizes the rotation of the head drum and simplifies the head drum assembly.

종래의 헤드드럼 장치는 드럼축에 상, 하 드럼을 설치하고 하부드럼의 하부에 드럼을 회전시킬수 있는 모터를 설치하고 있었는바, 이는 상, 하 드럼의 베어링 간격이 넓게되어 있어 드럼의 지지가 안정적이지 못하였으며 이에따라 회전하는 드럼이 유동되어 화면등의 재생이 원할하게 이루어지지 못하였고, 또한 하부드럼의 하방에 드럼 구동용 모터를 설치하고 있었기 때문에 헤드드럼에 어셈블리의 구조가 복잡하고, 부피가 커지게되는 점등의 문제점이 있었다.In the conventional head drum device, the upper and lower drums are installed on the drum shaft, and the motor that rotates the drum is installed on the lower part of the lower drum. The bearing space of the upper and lower drums is widened, so the drum support is stable. Due to this, the rotating drum flows and the screen was not regenerated smoothly. Also, because the drum driving motor was installed under the lower drum, the assembly structure of the head drum was complicated and bulky. There was a problem with the lighting.

본 고안은 상기와 같은 종래의 문제점을 감안하여 상부드럼의 상부에 구동모터를 설치하고 상, 하 드럼사이에 브러쉬 드럼을 내재시키므로서 드럼의 회전을 안정시킬수 있으며 또 헤드드럼 어셈블리를 소형, 경량화시킬수 있도록 안출한 것으로 이를 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.The present invention, in view of the above-mentioned problems, by installing a drive motor on the upper drum upper and lower drums by embedding the brush drum can be stabilized the rotation of the drum and the head drum assembly can be made smaller and lighter When described in detail based on the accompanying drawings to be drawn out as follows.

축(1)상에 헤드(4)가 설치되는 상부드럼(2)과 하부드럼(3)을 설칠한 헤드드럼 장치에 있어서, 하부드럼(3)의 내부상방에 하부트랜스(5)를 설치하고 이의 상부에는 상, 하 베어링(8), (9)과 상부 트랜스(7)를 구비한 브러쉬드럼(6)을 설치하며 이의 상부에 상부드럼(2)을 고정설치하고, 상부드럼(2)의 상면에는 로터(10)를 설치하며, 축(1)의 상단에는 스테이터(12)를 가진 설치판(11)을 고정설치토록 하되, 이 설치판(11)은 상부드럼(2)의 상면으로 돌출되지 않도록 구성하여서 된 것이다.In the head drum device in which the upper drum 2 and the lower drum 3 are provided with the head 4 on the shaft 1, the lower transformer 5 is installed above the lower drum 3. In the upper part of the upper and lower bearings (8), (9) and the brush drum (6) having the upper transformer (7) is installed and the upper drum (2) is fixed to the upper part of the upper drum (2) The rotor 10 is installed on the upper surface, and the mounting plate 11 having the stator 12 is fixed to the upper end of the shaft 1, but the mounting plate 11 protrudes to the upper surface of the upper drum 2. It is configured to prevent.

이상과 같이 구성된 본 고안은 축(1)상단의 설치판(11)에 설치된 스테이터(12)에 전원을 인가하면, 스테이터(12)가 이에 근접된 로터(10)를 회전시키게 되며 로터(10)는 이에 고정된 상부드럼(2)가 상부트랜스(7)를 가진 브러쉬드럼(6)을 회전시키게 된다.According to the present invention configured as described above, when power is applied to the stator 12 installed on the mounting plate 11 on the upper end of the shaft 1, the stator 12 rotates the rotor 10 adjacent thereto and the rotor 10. The upper drum 2 fixed thereto rotates the brush drum 6 having the upper transformer 7.

상부드럼(2)이 회전되면 이와함께 헤드(4)가 회전되어 화면등을 재생시키게되며 브러쉬드럼(6)은 상, 하의 베어링(8), (9)에 의해서 축(1)을 중심으로 안정되게 회전하게 된다. 이때, 하브트랜스(5)를 가진 하부드럼(3)과 축(1)은 회전하지 않게되며, 로터(10)와 스테이터(12)의 작용에 따라서 상부드럼(2)과 브러쉬드럼(6)만 회전하게 된다.When the upper drum 2 is rotated, the head 4 is rotated together to regenerate the screen and the brush drum 6 is stabilized about the shaft 1 by the upper and lower bearings 8 and 9. Will rotate. At this time, the lower drum (3) and the shaft (1) having a half transformer (5) does not rotate, only the upper drum (2) and brush drum (6) in accordance with the action of the rotor 10 and the stator (12) Will rotate.

이와같은 본 고안은 상, 하의 드럼(2), (3)을 모두 회전시키지 않고 상부드럼(2)만을 회전시키며 또한 회전의 지지점은 브러쉬드럼(6)의 베어링(8), (9)으로 설정하므로서 회전부분의 지지간격을 좁게할수 있고 따라서 드럼의 회전을 안정적으로 할수 있으며, 또한 드럼을 회전시키는 모터가 상부드럼내에 설치되도록 하므로서 외형적으로는 상, 하 드럼만이 나타나게 되고 구조를 보다 간단하게 할수 있으며 소형, 경량화시킬수 있는 점등의 특징을 지닌 것이다.The present invention does not rotate both the upper and lower drums (2) and (3), only the upper drum (2) is rotated, and the support point of rotation is set to the bearings (8), (9) of the brush drum (6) Therefore, the supporting interval of the rotating part can be narrowed, and thus the drum can be rotated stably. Also, only the upper and lower drums appear in appearance so that the motor for rotating the drum is installed in the upper drum. It can be compact and light weight.
