It is in the internal static electricity drawer.
이하, 이 고안의 일실시예를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings.
제 2 도는 이 고안에 따른 단면구조도로서, 상, 하부드럼(1), (2)과 하부의 드럼모터(3)가 베어링(4)으로 지지되어 축(5)으로 고정되서 설치되고, 상기 드럼모터(3)의 축 (5)끝단의 오주연에 부쉬(6)가 체결부재(7)로서 고정되어 설치되며, 상기 부쉬(6)의 양측에는 균형을 유지하며 드럼내부에서 발생되는 자기장의 외부유출을 방지하도록된 백요크(Back Yoke)(8)가 설치되고, 이 백요크(8)의 일측상부와 상기 부쉬(6)사이에는 회전에 따른 완충작용을 하는 탄성부재(9)가 설치되며, 상기 백요크(8)의 상부에는 체결부재 (10)로서 고정된 스테이터(11)가 설치되고, 이 스테이터(11)의 상부에는 로우터(12)가 형성되며, 상기 상, 하부드럼(1), (2)하부와 연결된 드럼모터(3)의 일측저면과 드럼베이스 (13)와 메인덱크(14)는 체결부재(15)로서 고정시키고, 이측방향으로 상기 드럼베이스 (13)와 메인덱크(14)를 체결부재(16)로서 고정시키며, 상기 축(5)끝단 외주면에 형성된 부쉬(6) 일측끝단에는 고정홈(17)을 형성시키고, 상기 드럼베이스(13)와 메인덱크(14)에는 관통공(18)을 형성시켜서, 상기 고정홈(17)에 토션스프링(19)의 일측을 고정시키고, 타측은 상기 관통공(18)에 삽입시켜서 상기 스테이터(11)의 상부에 형성된 로우터(12)로부터 내부정전기가 상기 토션스프링(19)을 통하여 상기 메인덱크(14)로 인출되도록 구성된다.2 is a cross-sectional structure diagram according to the present invention, in which upper, lower drums (1) and (2) and lower drum motors (3) are supported by a bearing (4) and are fixed to the shaft (5) and installed. The bush 6 is fixedly installed as the fastening member 7 at the circumferential edge of the end of the shaft 5 of the motor 3, and the external leakage of the magnetic field generated in the drum is maintained on both sides of the bush 6. Back yoke (8) is provided to prevent the installation, and between the upper side of the one side and the bush (6) of the back yoke (8) is provided with an elastic member (9) for the buffering action according to the rotation, A stator 11 fixed as a fastening member 10 is installed on the top of the back yoke 8, and a rotor 12 is formed on the top of the stator 11, and the upper and lower drums 1, (2) The bottom of one side of the drum motor (3) connected to the bottom, the drum base 13 and the main deck 14 is fixed as the fastening member 15, and the drum bar in the lateral direction Fixing the switch 13 and the main deck 14 as the fastening member 16, and a fixing groove 17 is formed at one end of the bush 6 formed on the outer peripheral surface of the shaft 5 end, and the drum base 13 ) And the main deck 14 to form a through hole 18 to fix one side of the torsion spring 19 to the fixing groove 17, and the other side is inserted into the through hole 18 to stator 11. The internal static electricity from the rotor 12 formed on the top of the () is drawn out to the main deck 14 through the torsion spring (19).
이와같이 구성된 이 고안은 제 2 도에 나타낸 바와같이, 드럼모터(3)의 체결부재 (10)로서 고정된 스테이터(11)에 전류를 인가하면 자계가 발생하여 로우터(12)가 회전함에 따라 상부드럼(1)이 베어링(4)으로 지지된축(5)을 중심으로 회전하면 상기 상부드럼 (1)의 저면에 설치된 헤드(20)가 테이프 (도시하지 않음)의 신호를 읽어서 상기 하부드럼 (2)상의 로터리 트랜스(23)로 보내고 이 로타리 트랜스(23)는 하부에 고정되어 회전하지 않는 스테이터 트랜스(24)로 신호를 전달하게 된다.In this configuration, as shown in FIG. 2, when an electric current is applied to the stator 11 fixed as the fastening member 10 of the drum motor 3, a magnetic field is generated and the upper drum rotates as the rotor 12 rotates. When (1) rotates about the shaft (5) supported by the bearing (4), the head (20) installed on the bottom of the upper drum (1) reads the signal of the tape (not shown) to the lower drum (2) The rotary transformer 23 is transmitted to the stator transformer 24 which is fixed to the lower part and which does not rotate.
또한, 스테이터(11)와 로우터(12)를 종래의 제 1 도와 달리 길이방향으로 설치하고, 상기 스테이터(11)의 두께를 대폭축소시킴으로써, 드럼모터(3)의 싸이즈가 대폭 축소되며, 백요크(8)의 일측상부와 부수(16) 사이에는 탄성부재(9)를 설치함으로써, 회전에 따른 완충작용을 할 수 있게 되고, 상기 부수(16)의 양측에는 백요크(8)를 설치함으로 인한 균형을 유지할 수 있게 되고, 드럼내부에서 발생되는 자기장의 외부유출을 방지할수 있게 된다.In addition, the stator 11 and the rotor 12 are installed in the longitudinal direction differently from the conventional first one, and by greatly reducing the thickness of the stator 11, the size of the drum motor 3 is greatly reduced, and the back yoke By installing the elastic member 9 between the upper side of one side of the (8) and the number of copies 16, it is possible to perform a buffering action due to the rotation, due to the installation of the back yoke (8) on both sides of the number of copies (16) The balance can be maintained, and the external leakage of the magnetic field generated inside the drum can be prevented.
또한, 축(5)끝단의 외주연에 형성된 부쉬(6)일측에 고정홈(17)과, 드럼베이스 (13)와 메이덱크(14)에 형성된 관통공(18)을 형성시켜서 토션스프링(19)의 일측은 상기 고정홈(17)에 고정시키고, 타측은 상기 관통공(18)에 삽입시켰기 때문에 로우터(12)로부터 인출되게되어 종래의 제 1 에서와 같이 드럼(1a)의 외부로 헤드브러쉬(21)가 노출설치되어 드럼의 싸이즈가 커지게 되는 등의 종래의 제반문제점이 해결된다.In addition, a torsion spring (19) is formed by forming a fixing groove (17) and a through hole (18) formed in the drum base (13) and the main deck (14) on one side of the bush (6) formed at the outer circumference of the shaft (5) end. One side of the) is fixed to the fixing groove 17, the other side is drawn out from the rotor 12 because it is inserted into the through hole 18, the head brush to the outside of the drum (1a) as in the first conventional The conventional problems, such as the exposure of 21, to increase the size of the drum, are solved.
이상에서와 같이, 이 고안에 따른 드럼의 내부정전기 인출장치를 사용함으로써, 캠코더나 비데오테이프레코더등의 드럼내부에서 발생되는 내부정전기르 드럼모터의 로우터로부터 토션스프링을 통하여 메인덱크로 효율적으로 인출시킬수 있어서 드럼의 사용수명을 대폭 향상시킬수 있으며, 드럼의 싸이즈를 경박단소화할 수 있는 등의 많은 장점이 구비된 매우 유용한 고안이다.As described above, by using the internal electrostatic drawing device of the drum according to the present invention, it is possible to efficiently draw out the main electrostatic drum drum from the rotor of the internal electrostatic drum motor generated in the drum such as a camcorder or a video tape recorder to the main deck through the torsion spring. It is possible to greatly improve the service life of the drum, it is a very useful design equipped with many advantages such as light and small size of the drum.
