본 고안은 비디오카세트에서 테이프를 끌어내어 헤드드럼에 세트하는 VTR의 로오딩기구와 함께 구동하는 F/E헤드아암에 있어서 특히 아암에 장착된 셔플라이 임피던스롤러 조립체의 구조를 간소화하여 생산원가의 절감과 조립작업을 간단하게함으로서 생산수율을 증대시킬 수 있도록 한 것이다.The present invention reduces the production cost by simplifying the structure of the shuffle impedance roller assembly mounted on the arm, especially for the F / E head arm which drives the tape from the video cassette and sets it on the head drum. By simplifying the assembly and assembly work it is possible to increase the production yield.
종래에는 제3도에 도시한 바와같이 메인샤시(31)에 고정된 스터드(32)에 단층면을 주어 이에 F/E헤드아암(33), 와샤(34), 탄성스프링(35), 롤러후렌지A(36). 롤러후렌지B(39)를 조립하고 마지막으로 조정너트(40)를 체결하게 되어 있으며 가이드포스터의 높이조정에 따라서 서플라이임피던스롤러(39)의 높이를 조정할때에는 상기 조정너트(40)를 조이거나 풀어 텐숀스프링(35)의 탄성에 의해 롤러의 높이를 조정하게 된다.Conventionally, as shown in FIG. 3, a single-sided surface is provided to the studs 32 fixed to the main chassis 31 so that the F / E head arm 33, washer 34, elastic spring 35, roller flange A (36). Assemble the roller flange B (39) and finally tighten the adjustment nut (40). When adjusting the height of the supply impedance roller (39) according to the height adjustment of the guide poster, tighten or loosen the adjustment nut (40). The height of the roller is adjusted by the elasticity of the spring 35.
그러나 이러한 종래의 서플라이임피던스롤러 조립체는 부품수가 많아 그만큼 조립공정이 복잡해지는 문제점이 발생하여 생산원가 상승을 초래하게 된다. 따라서 고정밀한 수직에 의해 균일한 동심도가 요구되는 서플라이임피던스롤러 조립체는 구성을 간소화하는 것이 바람직하다.However, such a conventional supply impedance roller assembly has a large number of parts, which causes a problem in that the assembly process is complicated, resulting in an increase in production cost. Therefore, it is desirable to simplify the configuration of a supply impedance roller assembly which requires uniform concentricity by high precision vertical.
본 고안의 목적은 덱크의 메인샤시에 돌기와 고정나사에 의해 결합되는 스프링고정용 홀더와, 상기 홀더상에 스피닝 고정된 트러스트보스와, 트러스트보스의 표면에 축삽입되는 F/E헤드아암 및 탄성스프링과를 구비하고 임피던스롤러 샤프트의 중단에 압입된 롤러스크류, 하 후렌지와 그위로 롤러를 회전가능하게 압입하여 상 후렌지의 압입에 의해 서플라이 입피던스롤러 조립체를 구성함으로써 롤러샤프트 하단을 상기한 트러스트보스의 세트스크류에 의해 간단히 조정 및 조립할 수 있는 것을 제공하는데 있다.An object of the present invention is a spring fixing holder coupled to a deck main chassis by a protrusion and a fixing screw, a thrust boss fixed on the holder, an F / E head arm and an elastic spring inserted into the surface of the thrust boss. The thrust boss of the roller shaft having a lower end of the roller shaft by forming a supply mouth roller assembly by rotatably pressing the roller screw, the lower flange and the roller thereon, which is press-fitted to the interruption of the impedance roller shaft, and the upper flange is pressed. It is to provide a thing that can be easily adjusted and assembled by a set screw.
본 고안에 있어서 임피던스롤러는 내외경을 가공시 샤프트홀을 일체로 형성하고 샤프트 중단으로 부터 롤러스크류를 압입한다. 또한 상기 롤러 스크류 위로 압입에 의해 조립되는 후렌지는 연삭다듬질의 요철을 제거하도록 랩핑(lapping)가공하여 고정밀도를 유지하도록 한다. 이하에서 본 고안의 실시예를 상세히 설명하면 제1도는 서플라이 입피던스 롤러 조립체의 부품을 분해한 상태이다.In the present invention, the impedance roller forms a shaft hole integrally when machining the inner and outer diameters and presses the roller screw from the shaft stop. In addition, the flange assembled by press-fitting onto the roller screw is lapping to remove the irregularities of the grinding finish to maintain high precision. Hereinafter, an embodiment of the present invention will be described in detail with reference to FIG. 1 in a state in which parts of a supply mouth roller assembly are disassembled.
덱크의 메인샤시(1)상에 돌기(2a) 및 고정나사(32b)에 의해 체결되는 스프링고정용 L자형 홀더(2)상에 트러스트보스(3)의 하단돌기(4)를 홀더(2)에 스피닝하여 고정시키고 상기 트러스트보스 표면에 F/E헤드아암(5)을 축삽입한다. 또한 F/E헤드아암(5)의 상측으로 텐숀스프링(6)을 개재시켜 스프링의 일단이 상기한 홀더(2)에 고정되도록함으로써 F/E헤드아암에 텐숀을 부여하여 아암에 장착된 F/E헤드아암(5a)가 비디오테이프에 접촉하면서 테이프텐숀을 주게되어 있다.The lower end projection 4 of the thrust boss 3 on the spring fixing L-shaped holder 2 fastened by the projection 2a and the fixing screw 32b on the main chassis 1 of the deck is held by the holder 2. Spinning on and fixation is performed, and the F / E head arm 5 is pivotally inserted into the trust boss surface. In addition, the tension spring 6 is fixed to the holder 2 by interposing a tension spring 6 above the F / E head arm 5 so as to give tension to the F / E head arm, thereby mounting the F / E head arm. The E-head arm 5a comes in contact with the video tape to give a tape tension.
그리고 임피던스롤러(7)는 내경에 롤러샤프트(8)를 회전가능하게 삽입한 상태에서 샤프트 중단에 롤러스크류(9) 및 하 후렌지(10)를 압입하고 샤프트 상단에 슬로딩홈이 있는 상 후렌지(11)를 삽입한다. 이때 상하 후렌지(10)(11)사이에 위치한 입피던스롤러(7)의 간격은 조립시 이미 설정되어 있다. 다음에 롤러 샤프트(8)의 하단을 상기한 트러스트보스(3)에 삽입하되 롤러후렌지 아래의 롤러 스크류가 트러스트보스의 상단 요입부(3a)내에 위치하도록 샤퍼트를 결합함과 동시에 트러스트보스의 세트 스크류(3b)를 이용하여 서플라이 임피던스롤러의 조립체르 완성하는 것이다.In addition, the impedance roller 7 press-fits the roller screw 9 and the lower flange 10 to the shaft stop in a state in which the roller shaft 8 is rotatably inserted in the inner diameter, and the upper flange having a slotting groove at the top of the shaft ( 11) Insert. At this time, the gap between the upper and lower flange 10 and 11, the feedback roller 7 is already set during assembly. Next, the lower end of the roller shaft 8 is inserted into the above-mentioned thrust boss 3, and the set of thrust bosses is engaged at the same time as the chaperet is engaged so that the roller screw under the roller flange is located in the upper recess 3a of the thrust boss. The assembly of the supply impedance roller is completed using the screw 3b.
이와같은 본 고안의 F/E헤드아암(5a)와 서플라이 임피던스롤러(7)에 접촉하여 주행하는 비디오테이프가 임피던스 롤러의 상후렌지(10)에 접촉하여 테이프하단이 구결질 경우에는 트러스트보스(3)의 세트 스크류(3b)를 풀러 임피던스롤러의 높이를 간단히 조정할 수 있고 또한 임피던스롤러 조립체는 부품수 절감에 의해 작업공정이 대폭절감되는 효과를 기대할 수 있는 것이다.When the video tape traveling in contact with the F / E head arm 5a and the supply impedance roller 7 of the present invention is in contact with the upper flange 10 of the impedance roller and the lower end of the tape is bent, the thrust boss 3 The height of the impedance roller can be easily adjusted by loosening the set screw 3b), and the impedance roller assembly can be expected to greatly reduce the work process by reducing the number of parts.
