본 고안은 브이씨알(VCR)등의 자기기록 재생장치의 헤드 크리너에 관한 것으로서 특히, 자기기록 재생장치의 헤드 드럼에 설치된 헤드를 청소하기 위한 헤드 크리너에 관한 것이다.The present invention relates to a head cleaner of a magnetic recording / playback apparatus such as VCR, and more particularly, to a head cleaner for cleaning a head provided in the head drum of the magnetic recording / playback apparatus.
브이씨알 및 디에이티등 자기기록 재생장치의 중요요소인 헤드 드럼의 헤드는 더럽혀지거나 이물질의 부착시, 영상과 물질의 재생에 결정적인 악영향을 초래하므로 주기적으로 청소를 실시해야 하는바, 통상적으로 별도의 클리닝 카세트를 이용하거나, 첨부 도면 제1도에 도시한 것과 같은 자체 헤드 클리닝 장치를 사용하고 있다.The head of the head drum, which is an important element of magnetic recording and reproducing apparatus such as V-Cal and DieT, has to be periodically cleaned because it is detrimental to the reproduction of images and materials when it is dirty or attached. A cleaning cassette is used, or its own head cleaning device as shown in FIG. 1 is used.
제1도의 통상적인 자체 클리닝 장치는 스폰지(1)를 외주에 부착시킨 회전롤러 (2)를 클리너 아암(3)의 일측단부에 형성된 축 지지부(4)에 축착시키고 상기 클리너 아암(3)의 타측 단부에 형성된 허브(5)를 본체 베이스(6)에 압입고정된 축(7)에 탄성체(8)와 와셔(9)를 개재하여 설치한 구성으로 되어있는바, 이러한 종래의 헤드 크리너는 자기기록 재생장치의 헤드 드럼이 회전함에 따라, 헤드 드럼에 설치된 헤드와 회전롤러(2)의 외주에 부착된 스폰지(1)가 접촉시, 마찰력으로 인하여 상기 회전롤러(2)가 동시에 회전하게 되고 이때, 스폰지(1)는 헤드와 연속접촉되어 마찰함으로써 헤드에 부착된 이물질을 청소하게 된다.The conventional self-cleaning apparatus of FIG. 1 adheres a rotating roller 2 having a sponge 1 attached to its outer circumference to an axial support 4 formed at one end of the cleaner arm 3, and the other side of the cleaner arm 3. The hub 5 formed at the end is provided with an elastic body 8 and a washer 9 provided on the shaft 7 fixed to the main body base 6 through a shaft 7. As the head drum of the regeneration apparatus rotates, when the head installed on the head drum and the sponge 1 attached to the outer circumference of the rotating roller 2 come into contact with each other, the rotating roller 2 rotates simultaneously due to frictional force. The sponge 1 cleans the foreign matter attached to the head by friction in continuous contact with the head.
그러나, 상기한 종래의 장치는 제4도 (a)에 도시한 바와같이 헤드를 청소해주는 스폰지(1)와 헤드가 접촉하는 부분이 항상 일정하게 되어, 헤드를 반복적으로 일정시간 이상 청소하면, 청소하는 부위만 집중적으로 오염이 되어 더 이상 청소효과가 없을 뿐 아니라 헤드를 더욱 오염시키는 결과를 초래하게 된다.However, in the above-described conventional apparatus, as shown in FIG. 4 (a), the part where the head comes in contact with the sponge 1 for cleaning the head is always constant, and the head is repeatedly cleaned for a predetermined time or more. Only contaminated areas are contaminated, resulting in no more cleaning effect and contaminating the head.
또한 스폰지(1)의 접촉부위가 항상 일정한 관계로 편마모현상이 발생하여, 스폰지(1)의 사용수명이 저하되어 비 경제적인 문제가 있다.In addition, uneven wear occurs because the contact portion of the sponge 1 is always constant, and the service life of the sponge 1 is lowered, resulting in an uneconomic problem.
도면중 미 설명부호 10은 회전롤러(2) 지지축을 나타낸 것이다.In the drawings, reference numeral 10 denotes the support shaft of the rotary roller 2.
본 고안은 상기와 같은 문제점을 해소하고자 안출한 것으로, 회전롤러의 하부 회전축 지지부 상면에 돌출돌기와 캠돌조를 형성시켜 회전롤러가 회전운동과 동시에 상하운동을 하면서 헤드를 청소할 수 있도록 한 것으로서, 이를 첨부도면에 의해 상세히 설명하면 다음과 같다.The present invention has been made to solve the above problems, by forming a protruding protrusion and a cam protrusion on the upper surface of the lower rotating shaft support portion of the rotary roller to enable the rotary roller to clean the head while moving up and down simultaneously with the rotational movement, attached to this When described in detail by the drawings as follows.
제2도 및 제3도에 도시한 바와같이 클리너 아암(11)의 축 지지부(12) 상단에 형성된 원형베이스(13)에 캠돌조(14)를 환상으로 형성하고, 스폰지와 같은 청소부재 (15)가 외주면에 부착된 회전롤러(16)의 하측 플랜지(17) 하면에는 상기 캠돌조(14)와 접촉되는 접촉돌기(18)를 형성하며, 축(19)의 상단부에 고정된 와셔(20)와, 회전롤러(16)의 상측 플랜지(21) 사이에는 탄성체(22)를 삽입하여서 된 것으로, 도면중 미 설명부호 23은 자기 기록 재생장치의 헤드 드럼에 부착된 헤드를 나타낸 것이다.As shown in FIG. 2 and FIG. 3, the cam protrusion 14 is annularly formed in the circular base 13 formed in the upper end of the shaft support part 12 of the cleaner arm 11, and the cleaning member 15 like a sponge is formed. ) Is formed on the bottom of the lower flange (17) of the rotary roller (16) attached to the outer circumferential surface to form a contact protrusion (18) in contact with the cam protrusion (14), the washer (20) fixed to the upper end of the shaft (19) And an elastic body 22 is inserted between the upper flange 21 of the rotary roller 16. In the drawing, reference numeral 23 denotes a head attached to the head drum of the magnetic recording and reproducing apparatus.
이와같이 된 본 고안의 작용효과를 설명하면 다음과 같다.When explaining the effect of the present invention made as follows.
헤드(23)가 설치된 자기기록 재생장치의 헤드 드럼이 회전할때 회전롤러(16)주위에 부착된 청소부재(15)를 헤드 드럼의 회전면과 접촉시키면 회전롤러(16)는 일정한 속도비를 가지고 회전하게 되며 이에따라 회전롤러(16)의 하면에 형성된 접촉돌기(18)는 원형베이스(13)상의 환형의 캠돌조(14)위를 따라 회전하게 되고, 상기 캠돌조(14)는 저부(低部)와 정부(頂部)가 높이차를 가지는 곡면의 형상이기 때문에 상기 청소부재(15)는 회전롤러(16)와 함께 회전운동과 동시에 일정한 폭을 가지는 상하운동을 하면서 헤드를 청소하게 된다.When the head drum of the magnetic recording and reproducing apparatus equipped with the head 23 rotates and the cleaning member 15 attached to the rotating roller 16 is brought into contact with the rotating surface of the head drum, the rotating roller 16 has a constant speed ratio. As a result, the contact protrusion 18 formed on the lower surface of the rotating roller 16 rotates along the annular cam protrusion 14 on the circular base 13, and the cam protrusion 14 is the bottom portion. ) And the top part (형상 部) because the shape of the curved surface having a difference in height, the cleaning member 15 is to clean the head while the vertical movement having a constant width at the same time as the rotational movement with the rotary roller 16.
첨부도면 제4도 (b)는 본 고안의 헤드 크리너 청소부재(15)가 헤드(23)와 접촉회전시의 접촉궤적을 나타내는 도면이다.4 (b) is a view showing a contact trace when the head cleaner cleaning member 15 of the present invention is in contact rotation with the head 23. As shown in FIG.
이상과 같이 본 고안은 헤드(23)가 청소부재(15)와 접촉회전시 회전운동과 함께 상하운동을 하게되어 청소부재(15)의 헤드 접촉면이 연속적으로 달라지게 되어 종래의 일정부위 접촉방식 보다 청소효과가 탁월할 뿐 아니라, 청소부재(15)의 오염으로인한 헤드(23)의 오염을 방지할 수 있고, 청소부재(15)의 동일부위를 계속 사용함에 따른 편마모 현상을 방지하며, 청소부재(15)의 사용수명을 늘려, 청소부재(15)를 조기교환해야 하는 번거로움을 덜수 있을뿐 아니라, 경제적으로도 큰 효과가 있다.As described above, the present invention makes the head 23 move upward and downward along with the rotational movement when the head 23 is in contact with the cleaning member 15 so that the head contact surface of the cleaning member 15 is continuously different than the conventional constant contact method. In addition to excellent cleaning effect, it is possible to prevent contamination of the head 23 due to contamination of the cleaning member 15, to prevent uneven wear caused by continuing to use the same portion of the cleaning member 15, cleaning member Increasing the service life of (15), not only to reduce the need for early replacement of the cleaning member 15, but also has a great economic effect.
