본 고안은 자기기록재생기의 텐션조절장치에 관한 것으로, 특히 텐션 조절기구의 텐션밴드가 릴테이블에서 분리되어 이탈됨을 방지하도록 한 자기기록재생기의 텐션조절장치에 관한 것이다.The present invention relates to a tension control device of a magnetic recorder, and more particularly, to a tension control device of the magnetic recorder to prevent the tension band of the tension control mechanism from being separated from the reel table.
종래의 비디오 테이프 레코더에는 테이프가 로딩상태에서 주행할 때에 테이프의 텐션을 일정하게 유지하기 위한 텐션조절기구가 채용되어 있으며, 이 텐션조절기구는 릴테이블의 외주면에 텐션밴드을 감고, 그 텐션밴드를 텐션암에 연결하여, 텐션아암이 테이프의 장력에 의해 유동됨에 따라 텐션밴드가 릴테이블에 가하는 마찰력이 가변되도록 함으로써 텐션을 조절하도록 되어 있다.A conventional video tape recorder employs a tension adjusting mechanism for maintaining a constant tension of the tape when the tape is running in a loaded state. The tension adjusting mechanism winds a tension band on the outer circumferential surface of the reel table and tensions the tension band. In connection with the arm, the tension is adjusted by varying the friction force applied by the tension band to the reel table as the tension arm is flowed by the tension of the tape.
이러한 종래의 텐션조절기구에는 릴테이블의 외주면에 감기어 있는 텐션밴드가 상부로 떠서 이탈됨을 방지하기 위한 이탈방수단이 설치되어 있으나, 종래의 이탈방지수단은 베이스플레이트에 플라스틱 몰드몰인 이탈방지편을 아웃서트(outsert)하여 형성하거나, 알루미늄들이 금속으로 형성한 이탈방지편을 베이스플레이트에 별도로 고정한 구성으로 되어 있으므로 별도의 부품 및 조립공정이 요구되어 생산성이 저하되고, 원가상승의 요인이 되는 결함이 있었다.The conventional tension control mechanism is provided with a release means for preventing the tension band wound on the outer circumferential surface of the reel table to float off, the conventional release prevention means is a release prevention piece of plastic mold mole on the base plate It is formed by outsert or the separation prevention piece made of aluminum is made of metal separately fixed to the base plate. Therefore, a separate part and assembly process are required, resulting in a decrease in productivity and a cost increase factor. There was this.
본 고안은 상기한 바와같은 종래의 결함을 해소하기 위하여 텐션암에 텐션밴드를 연결하는 연결레버가 상측으로 유동함을 방지하는 이탈 및 유동방지편을 베이스플레이트에 일체로 절곡형성하여 생산성을 향상하고, 원가 절감에 기여하도록 안출한 것인 바, 이러한 본 고안의 일실시례를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention improves productivity by integrally bending breakaway and flow prevention pieces integrally with the base plate to prevent the connecting lever connecting the tension band to the tension arm to flow upward in order to solve the conventional defect as described above. It will be devised to contribute to cost reduction, when described in detail with reference to the accompanying drawings an embodiment of the present invention.
제1도는 본 고안이, 적용된 텐션 조절장치의 평면도이고, 제2도는 제1도의 부분 종단면도이며, 제3도는 제1도의 요부 확대 분해사시도로서, 이에 도시한 바와같이, 베이스플레이트(1)상에 릴테이블(2)이 설치되고, 릴테이블(2)의 일측에는 텐션암(3)이 축(4)으로 축착되어 있다.FIG. 1 is a plan view of a tension adjusting device to which the present invention is applied, FIG. 2 is a partial longitudinal cross-sectional view of FIG. 1, and FIG. 3 is an enlarged exploded perspective view of the main part of FIG. 1, as shown here, on the base plate 1 The reel table 2 is provided, and the tension arm 3 is affixed to the shaft 4 at one side of the reel table 2.
상기 텐션암(3)은 선단부에 텐션포스트(5)가 고정되고, 후단부축에 연결레버 (6) (7)에 의해 텐션밴드(8)의 양단부가 연결되어 있으며, 텐션밴드(8)는 릴테이블(2)의 외주면에 감기어 있다.The tension arm 3 has a tension post 5 fixed to the distal end thereof, and both ends of the tension band 8 are connected to the rear end shaft by connecting levers 6 and 7, and the tension band 8 has a reel. It is wound around the outer peripheral surface of the table 2.
상기 텐션암(3)은 후단부에 형성된 걸림돌기(9)에 스프링(10)의 일단부가 연결되고, 그 스프링(10)의 타단부는 베이스플레이트(1)에 고정되어 텐션암(3)이 스프링 (10)에 의해 반시계 방향으로 탄력지지되어 있다.The tension arm 3 has one end of the spring 10 connected to the engaging protrusion 9 formed at the rear end thereof, and the other end of the spring 10 is fixed to the base plate 1 so that the tension arm 3 is secured. It is elastically supported counterclockwise by the spring 10.
상기 연결레버(7)는 본 고안에 따라 형성된 이탈 및 유동방지편(11)에 의하여 상측으로의 유동이 방지되고, 이에 따라 텐션밴드(8)가 릴테이블(2)의 외주면에서 이탈됨을 방지하도록 되어 있다.The connecting lever 7 is prevented to flow upward by the separation and flow prevention piece 11 formed in accordance with the present invention, thereby preventing the tension band 8 is separated from the outer peripheral surface of the reel table (2) It is.
상기 이탈 및 유동방지편(11)은 상기 베이스플레이트(1)에 일체로 절곡 형성되어 있고, 상단부에 ㄱ자형 절곡부(12)가 형성되어 있다.The separation and flow prevention piece 11 is formed integrally bent to the base plate 1, the be-shaped bent portion 12 is formed at the upper end.
도면에서 13은 메인 브레이크를 보인 것이고, 14는 소프트 브레이크를 보인 것이다.13 shows the main brake and 14 shows the soft brake.
상기한 바와같은 텐션 조절장치는 정지 모드에서는 제1도에 실선으로 도시한 상태를 유지하며, 플레이 모드에서는 가상선의 상태에서 공지의 동작으로 주행기구에 의해 주행되는 테이프의 텐션을 일정하게 유지한다.The tension adjusting device as described above maintains the state shown by the solid line in FIG. 1 in the stop mode, and maintains the tension of the tape driven by the traveling mechanism in a known operation in the state of the virtual line in the play mode.
이러한 텐션 조절장치는 릴테이블(2)에 감겨져 있는 텐션밴드(2)가 이탈됨이 없이 안정하게 유지되어야 만이 테이프의 텐션을 일정하게 유지할 수 있게 되는바, 본 고안에 따라 베이스플레이트(1)에 이탈 및 유동방지편(11)이 일체로 형성되어 그 이탈 및 유동방지편(11)으로 하여금 연결레버(7)가 상측으로 유동되지 않도록 되어 있으므로 텐션밴드(8)가 릴테이블(2)의 외주면에서 이탈되지 않고 안정하게 유지될 수 있으며, 이에다라 텐션조절 작용을 항상 안정하게 행할 수 있게 된다.This tension adjusting device is to maintain the tension of the tape only if the tension band (2) wound on the reel table (2) is not separated, so that the base plate (1) according to the present invention The separation and flow prevention piece 11 is integrally formed so that the separation and flow prevention piece 11 does not allow the connecting lever 7 to flow upward. It can be maintained stably without departing from this, and thus the tension control action can be performed stably at all times.
이상에서 설명한 바와같은 본 고안은 상기 베이스플레이트(1)에 이탈 및 유동방지편(11)을 일체로 절곡 형성한 구성이므로 별도의 부품 및 조립공정이 요구되지 않아 생산성을 향상할 수 있고, 제품의 원가 절감에도 기여하는 이점이 있다.The present invention as described above is a configuration formed by bending the separation and flow prevention piece 11 integrally to the base plate (1), so no separate parts and assembly process is required, thereby improving productivity, It also has the advantage of contributing to cost reduction.
