본 고안은 브이씨알의 핀치로울러 청소장치에 관한 것으로, 특히 핀치로울러에 청소부재를 항시 탄력적으로 접촉시켜 테이프의 이물질을 제거함과 아울러 테이프에 이물질이 묻혀지는 것을 방지할 수 있게한 브이씨알의 핀치로울러 청소장치에 관한 것이다.The present invention relates to a pinch roller cleaning device of V-Cal. In particular, the pinch roller of the V-CAL can remove the foreign matter from the tape by elastically contacting the cleaning member with the pinch roller at all times. It relates to a cleaning device.
일반적인 브이씨알의 테이프 주행계는 제1도에 도시한 바와같이, 재생모드 또는 역재생모드에는 캡스턴 샤프트(1)에 핀치로울러(2)가 소정의 압력으로 접촉되어, 캡스턴 샤프트(1)의 회전으로 핀치로울러(2)도 회전되면서 테이프(3)를 도시한 화살표 A방향 또는 B방향으로 주행시키게 되며, 정지모드시에는 별도의 구동에 의하여 캡스턴 샤프트(1)로부터 핀치로울러(2)가 일정거리로 이격되므로 테이프(3)가 주행되지 못하도록 되어 있다.As shown in Fig. 1, the tape running system of the general V-AL has a pinch roller 2 contacting the capstan shaft 1 at a predetermined pressure in the regeneration mode or the reverse regeneration mode, so that the capstan shaft 1 rotates. The pinch roller 2 is also rotated so as to drive the tape 3 in the direction of arrow A or B shown in the drawing. In the stop mode, the pinch roller 2 is separated from the capstan shaft 1 by a separate drive. Since the tape 3 is spaced apart from each other, the tape 3 is prevented from running.
도면중 미설명 부호 4는 권취측 안내포스트, 5는 헤드드럼을 보인 것이다.In the figure, reference numeral 4 is a winding-side guide post, 5 is a head drum.
그러나, 상기한 바와같은 일반적인 브이씨알의 테이프 주행동작에 있어서는 테이프(3)이 표면에 묻은 먼지등의 이물질이 회전되는 핀치로울러(2)로 옮겨져 다른 테이프(3)의 사용시 핀치로울러(2)의 이물질이 테이프(3)로 다시 옮겨지게 됨으로써 테이프(3)를 손상시킬 뿐만 아니라 특히 역재생모드시에 핀치로울러(2)의 이물질이 헤드드럼(5)의 비디오헤드에 옮겨져 화질을 저하시키거나 심할 경우에는 핀치로울러(2)의 이물질에 의하여 테이프(3)가 휘감기게될 경우에는 테이프(3)에 치명적인 손상을 주고, 자동으로 브이씨알의 동작이 정지되는 등의 여러 문제점이 있었다.However, in the tape running operation of the general V-seal as described above, the tape 3 is moved to the pinch roller 2 in which foreign matter such as dust on the surface is rotated, so that the pinch roller 2 of the other tape 3 is used. As the foreign matter is transferred back to the tape 3, it not only damages the tape 3, but also foreign matter in the pinch roller 2 is transferred to the video head of the head drum 5, particularly in the reverse play mode, so as to degrade or deteriorate the image quality. In the case, when the tape 3 is wound around by the foreign matter of the pinch roller 2, the tape 3 is fatally damaged, and there are various problems such as automatic stopping of the V-Cal.
본 고안은 상기한 바와같은 종래의 문제점을 해소하기 위하여 안출한 것으로, 핀치암에 청소부재가 고정된 레버를 회동 가능하게 설치하고, 상기 레버를 비틀림 스프링으로 탄력 지지하여 핀치로울러에 청소부재를 탄력접촉함으로써 핀치로울러의 회전시 테이프의 이물질을 제거함과 아울러 테이프에 이물질이 묻혀지는 것을 방지할 수 있도록 구성한 것인 바, 이하 본 고안을 첨부 도면에 의하여 설명하면 다음과 같다.The present invention has been made in order to solve the conventional problems as described above, to install the lever fixed to the pinch arm rotatable, and to support the lever with a torsion spring elasticity to the pinch roller resilient cleaning member When the contact by the pinch roller is rotated to remove the foreign material on the tape and to prevent the foreign material is buried in the tape is configured to prevent the present invention will be described below with reference to the accompanying drawings.
제2도는 본 고안에 의한 브이씨알의 핀치로울러 청소장치 구성을 보인 사시도이고, 제3도는 제2도의 구성을 보인 평면도이며, 제4도는 제2도의 구성을 보인 분해사시도로서, 이에 도시한 바와같이, 캡스턴 샤프트(11)의 일측에 핀치로울러(12)가 회전 가능하게 설치된 핀치암(13)이 힌지축(14)을 중심으로 회전 가능하게 설치된 것에 있어서, 상기 핀치암(13)의 일측연부에 수직벽(13a) 및 수평부(13b)를 절곡 형성하여, 상기 수평부(13b)에 레버(15)의 축(16)을 회전 가능하게 결합하고, 상기 축(16)에 비틀림 스프링(17)을 삽입하여 일측지지간(17a)을 레버(15)의 상면에 형성한 고정돌기(15a)에 걸리게 함과 아울러 타측지지간(15b)을 힌지축(14)에 걸리게 하며, 상기 레버(15)의 선단부에 만곡고정부(15b)를 형성하여, 그 만곡고정부(13b)에 핀치로울러(12)의 이물질을 닦아내기 위한 청소부재(18)를 부착 고정하여 구성한 것으로, 도면중 미설명 부호 19는 테이프, 20은 권취측 안내포스트를 보인 것이다.Figure 2 is a perspective view showing the configuration of the pinch roller cleaning device of the V-Cal according to the present invention, Figure 3 is a plan view showing the configuration of Figure 2, Figure 4 is an exploded perspective view showing the configuration of Figure 2, as shown here The pinch arm 13 rotatably installed at one side of the capstan shaft 11 is rotatably installed around the hinge shaft 14, and the pinch arm 13 is rotatably formed at one side edge of the pinch arm 13. The vertical wall 13a and the horizontal portion 13b are bent to form a rotatable coupling of the shaft 16 of the lever 15 to the horizontal portion 13b, and the torsion spring 17 to the shaft 16. Inserts one side support section (17a) to the locking projection (15a) formed on the upper surface of the lever 15, and the other support section (15b) to the hinge shaft (14), the lever (15) A curved fixing part 15b is formed at the tip of the pin, and the foreign matters of the roller 12 are wiped off by the pinch roller 12b on the curved fixing part 13b. Configured to be attached to secure the cleaning members 18, the drawing reference numeral 19 of the tape 20 is showing the take-up side guide post.
이와같이 구성되는 본 고안에 의한 브이씨알의 핀치로울러 청소장치는 레버(15)가 비틀림 스프링(17)의 탄성에 의하여 축(16)을 중심으로 반시계 방향으로의 회동력을 갖게 되므로 핀치로울러(12)에 레버(15)의 만곡고정부(15b)에 고정된 청소부재(18)가 항시 탄력적으로 접촉되어 있게 된다.The pinch roller cleaning device of V-Cal according to the present invention configured as described above has a pinch roller 12 because the lever 15 has a rotational force in the counterclockwise direction about the axis 16 due to the elasticity of the torsion spring 17. ), The cleaning member 18 fixed to the curved fixing part 15b of the lever 15 is always in elastic contact.
이와같은 상태에서 정지모드 또는 역재생 모드시에는 별도의 구동에 의하여 핀치암(13)이 힌지축(14)을 중심으로 반시계 방향으로 회동되어 캡스턴 샤프트(11)에 핀치로울러(12)가 소정의 압력으로 접촉되므로 테이프(19)가 도시한 화살표 A 또는 B방향으로 이동하게 되며, 따라서 테이프(19)의 이물질이 핀치로울러(12)에 옮겨지게 되면, 그 이물질은 핀치로울러(12)에 탄력 접촉된 청소부재(18)에 의하여 제거되므로 테이프(19)는 항시 깨끗한 상태를 유지할 수 있는 것이다.In this state, in the stop mode or the reverse regeneration mode, the pinch arm 13 is rotated counterclockwise around the hinge shaft 14 by a separate driving so that the pinch roller 12 is fixed to the capstan shaft 11. Since the tape 19 is moved in the direction of arrow A or B as shown in the drawing, when the foreign matter of the tape 19 is transferred to the pinch roller 12, the foreign material is elastic to the pinch roller 12. The tape 19 is always kept clean because it is removed by the cleaning member 18 in contact.
또한, 테이프(19)에 묻혀진 점착성이 있는 이물질에 의하여 테이프(19)가 핀치로울러(12)에 눌러 붙어 감기게될 경우에는 청소부재(18)에 의하여 테이프(19)에 접착된 테이프(19)를 분리시켜 오동작을 방지하게 된다.In addition, when the tape 19 is pressed and wound on the pinch roller 12 by the sticky foreign matter buried in the tape 19, the tape 19 adhered to the tape 19 by the cleaning member 18. This prevents malfunction.
한편, 정지모드일 경우에는 별도의 구동에 의하여 핀치암(13)의 힌지축(14)을 중심으로 시계방향으로 회동되어 캡스턴 샤프트(11)로부터 핀치로울러(12)를 분리시키게 되며, 이때에도 핀치로울러(12)에는 청소부재(18)가 탄력적으로 접촉된 상태를 유지하게 된다.Meanwhile, in the stop mode, the pinch roller 12 is rotated clockwise around the hinge shaft 14 of the pinch arm 13 by a separate driving to separate the pinch roller 12 from the capstan shaft 11. The roller 12 maintains a state in which the cleaning member 18 is in elastic contact.
이상에서 설명한 바와같은 본 고안은 핀치로울러의 외주면에 붙은 이물질을 제거하여 테이프의 손상을 방지할 뿐만아니라 비디오헤드의 오염을 방지하여 화질이 저하되는 현상을 방지할 수 있으며, 오동작을 방지하는 등의 효과가 있다.As described above, the present invention not only prevents the tape from being damaged by removing foreign substances adhering to the outer circumferential surface of the pinch roller, but also prevents the degradation of the image quality by preventing the contamination of the video head. It works.
