일반적으로 VTR 등의 자기 기록/재생장치에는 자기 기록매체로부터 정보를 스캐닝하는 회전 자기헤드가 채용되어 있다. 그 회전 자기헤드는 상부드럼과 하부드럼으로 구성되는 회전헤드드럼의 상부드럼에 설치된다. 이와 같이 회전 자기헤드가 설치된 상부드럼을 회전시키기는 모터가 회전헤드드럼에 설치되는데, 그 모터를 회전헤드드럼에 고정시키는 종래의 고정장치가 제1,2도에 개략적으로 도시되어 있다.In general, a magnetic recording / reproducing apparatus such as a VTR employs a rotating magnetic head for scanning information from a magnetic recording medium. The rotating magnetic head is mounted on the upper drum of the rotating head drum which consists of an upper drum and a lower drum. In this way, a motor for rotating the upper drum provided with the rotating magnetic head is installed in the rotating head drum. A conventional fixing device for fixing the motor to the rotating head drum is schematically illustrated in FIGS.
회전 헤드드럼(10)은 자기헤드(미도시)가 설치되는 상부드럼(1)과 베이스(3)에 나사(12) 고정되는 하부드럼(2)으로 구성되어 있다. 상부드럼(1)에는 샤프트(9)가 압입설치되어 있으며, 그 샤프트(9)는 모터(11)의 회전자(7)와 압입되어 있다. 상기 모터(11)는 고정자(6)와 회전자(7)로 구성되어 있으며, 고정자(6)는 회로기판(4)과 전기적으로 연결되어 있고 몰드물(5)에 의해 회로기판(4)에 부착되어 있다. 그리고 고정자(6)는 나사(8)로 하부드럼(2)에 고정설치되어 있다.The rotating head drum 10 is composed of an upper drum 1 on which a magnetic head (not shown) is installed and a lower drum 2 fixed on a screw 12 to a base 3. The upper drum 1 is press-fitted with a shaft 9, and the shaft 9 is press-fitted with the rotor 7 of the motor 11. The motor 11 is composed of a stator 6 and a rotor 7, the stator 6 being electrically connected to the circuit board 4 and connected to the circuit board 4 by a mold 5. Attached. The stator 6 is fixed to the lower drum 2 with screws 8.
그런데, 상기 고정자(6)는 제2도에 도시한 바와 같이 다수의 나사(8)로 하부드럼(2)에 고정설치되므로 조립시 조립공수가 많고 부품이 많아 소요되어 생산능률이 저하되는 문제점이 있었다.However, the stator 6 is fixed to the lower drum 2 with a plurality of screws 8, as shown in FIG. .
본 고안은 상기의 문제점을 해결하기 위하여 안출된 것으로서, 모터의 고정자를 하부드럼에 고정설치하기가 간편하도록 그 구조를 개선한 헤드드럼 구조체를 제공하는 데 그 목적이 있는 것이다.The present invention has been made to solve the above problems, and an object of the present invention is to provide a head drum structure having an improved structure so that the stator of the motor is easily fixed to the lower drum.
상기 목적을 달성하기 위하여 본 고안은 샤프트를 갖는 상부드럼과, 그 샤프트를 관통지지하는 하부드럼과, 하부드럼에 고정결합되는 고정자 및 하부드럼을 관통한 상부드럼의 샤프트에 결합되는 회전자로 이루어진 모터를 구비하는 헤드드럼 구조체에 있어서, 상기 하부드럼에 결합홈이 형성되고, 모터의 고정자에는 그 결합홈에 탄력적으로 끼워져 결합되는 훅킹부재가 구비되어 된 것을 특징으로 한다.In order to achieve the above object, the present invention comprises an upper drum having a shaft, a lower drum supporting the shaft, a stator fixedly coupled to the lower drum, and a rotor coupled to the shaft of the upper drum passing through the lower drum. In the head drum structure having a motor, a coupling groove is formed in the lower drum, and the stator of the motor is provided with a hooking member that is elastically fitted in the coupling groove.
본 고안의 특징에 의하면, 상기 고정자는 훅킹부재에 의해서 결합홈이 형성된 하부드럼에 결합고정된다. 따라서 고정자의 고정작업을 간편하게 할 수 있으며, 또한 간단한 구조로서 조립부품수를 절감할 수 있다.According to a feature of the present invention, the stator is fixedly coupled to the lower drum formed with a coupling groove by the hooking member. Therefore, the fixing work of the stator can be simplified, and the number of assembly parts can be reduced with a simple structure.
