본 고안은 양면 광디스크플레이어용 픽업의 트래킹조정구조에 관한 것으로, 보다 상세하게는 특수 드라이버를 사용하지 않고 일반적으로 통용되는 십자 혹은 일자 드라이버로 간단하게 조정할 수 있도록 한 양면 광디스크플레이어용 픽업의 트래킹조정구조에 관한 것이다.The present invention relates to a tracking adjustment structure of a pickup for a double-sided optical disc player. More specifically, a tracking adjustment structure of a pickup for a double-sided optical disc player can be easily adjusted with a cross or flat head screwdriver. It is about.
일반적으로 광디스크플레이어의 양면 재생용 광픽업은 한 면을 재생한 후 상부틸트베이스로 이동하여 계속적으로 다른 면을 재생하게 되는 바, 상기 상부 틸트베이스(11)에 설치된 가이드봉(12)이 어느 한 쪽으로 편중될 경우 트래킹조정을 하게 된다.In general, an optical pickup for reproducing both sides of an optical disc player moves to an upper butyl base after reproducing one side and continuously reproducing the other side. The guide rod 12 installed on the upper tilt base 11 may be any one. If it is biased toward the side, tracking adjustment will be made.
이를 위하여 종래에는 제1도에 도시된 바와 같이, 별도의 조정브라켓(10)이 상기 상부틸트베이스(11)에 체결나사 (16)로 체결되어 있고, 상기 조정브라켓(10)은 통상 조정공(13)이 천공되어 있어 특수한 형태의 편심드라이버(15)의 편심부(15A)를 상기 조정브라켓(10)상에 형성된 드라이버 삽입공(14)에 삽입한 후 회전시킴으로써 상기 조정브라켓(10)이 상기 체결나사 (16)를 중심으로 회동되도록 하여 상기 가이드봉(12)의 미세조정이 이루어지도록 하고, 작업이 끝나면 상기 체결나사 (16)를 완전히 조여 고정하도록 되어 있다.To this end, conventionally, as shown in FIG. 1, a separate adjustment bracket 10 is fastened to the upper butyl base 11 with a fastening screw 16, and the adjustment bracket 10 is usually used as an adjustment hole ( 13) is perforated to insert the eccentric portion 15A of the special type eccentric driver 15 into the driver insertion hole 14 formed on the adjustment bracket 10, and then rotate the adjustment bracket 10 by It is to be rotated about the fastening screw 16 to make fine adjustment of the guide rod 12, and when the work is completed, the fastening screw 16 is completely tightened and fixed.
그러나, 이러한 통상적인 구조하에서는 픽업의 트래킹조정을 할 때마다 특수한 형태의 조정용 드라이버, 예컨대 편심드라이버(15) 등을 별도로 소지해야 하는 불편함이 있었다.However, under such a conventional structure, it is inconvenient to carry a special type of adjustment driver, for example, an eccentric driver 15, each time the tracking adjustment of the pickup is carried out.
본 고안은 이러한 불편함을 해소하기 위한 것으로, 원통형의 기저부와, 상기 기저부상에 편심으로 형성된 나사부로 이루어진 편심부재를 상부틸트베이스상면에 형성된 편심부재삽입홈에 삽입하고 조정브라켓 상에 천공된 조정공 내측에 상기 편심부재의 나사부를 끼우는 한편, 상기 조정브라켓의 하방 절곡부 상에 가이드봉삽입공을 천공함으로써, 수리작업에 필수적으로 동반되는 특수한 조정용드라이버를 별도로 지니고 다닐 필요가 없이 일반적인 십자 혹은 일자 드라이버로 용이하게 조정할 수 있도록 한 새로운 형태의 양면 광디스크플레이어용 픽업의 트래킹조정구조를 제공하는데 그 목적이 있다.The present invention is to solve this inconvenience, insert the eccentric member consisting of a cylindrical base portion, and a screw portion formed eccentrically on the base portion into the eccentric member insertion groove formed on the upper butyl base and adjusted perforated on the adjustment bracket By inserting the threaded portion of the eccentric member inside the ball, and drilling the guide rod insertion hole on the lower bent portion of the adjustment bracket, there is no need to carry a special adjustment driver that is essential to the repair work, without having to carry a separate cross or date It is an object of the present invention to provide a tracking adjustment structure of a pickup for a double-sided optical disc player, which can be easily adjusted by a driver.
이하 첨부된 도면에 의하여 본 고안에 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
본 고안은 제2도 및 제3도에 도시한 바와 같이, 원통형의 기저부(20A)와, 상기 기저부(20A)상에 편심으로 형성된 나사부(20B)로 이루어진 편심부재(20)를 상부틸트베이스(21) 상면에 형성된 편심부재삽입홈(22)에 삽입하고 조정브라켓(24)상에 천공된 조정공(26) 내측에 상기 편심부재(20)의 나사부(20B)를 끼우는 한편, 상기 조정브라켓(24)의 하방 절곡부상에 가이드봉삽입공(27)을 천공하여 된 특징을 갖는다.2 and 3, an eccentric member 20 composed of a cylindrical base portion 20A and a threaded portion 20B eccentrically formed on the base portion 20A is provided with an upper butyl base ( 21) Insert the screw portion 20B of the eccentric member 20 into the eccentric member insertion groove 22 formed in the upper surface and the adjustment hole 26 drilled on the adjustment bracket 24, while the adjustment bracket ( The guide rod insertion hole 27 is drilled on the lower bent portion 24.
이와 같은 본 고안에서, 상기 편심부재(20)는 기저부(20A)와 나사부(20B)로 이루어지는 바, 상기 기저부(20A)는 납작한 원통형의 것으로 그 상면에 나사부(20B)가 편심으로 돌출형성된 구조이며 상기 나사부(20B)의 상단부에 나사머리를 형성해 주어 일반 드라이버로 조정할 수 있도록 한다.In the present invention, the eccentric member 20 is composed of a base portion 20A and a screw portion 20B, the base portion 20A is a flat cylindrical structure of which the screw portion 20B protrudes eccentrically on its upper surface. A screw head is formed at the upper end of the screw portion 20B so that it can be adjusted by a general driver.
이와 같은 편심부재(20)를 수용할 수 있도록 상부틸트베이스(21)에 편심부재삽입홈(22)을 요홈형태로 형성하며 그 수직 상방에 상기 조정브라켓(24)의 조정공(26)이 놓여지도록 하되, 상기 나사부(20B)가 상기 조정공(26)을 통하여 노출되도록 함으로써, 상기 나사부(20B)를 드라이버(28)로 돌려주면 상기 조정브라켓(24)이 체결나사 (16)를 중심으로 좌우 회동하게 되고, 이에 따라 상기 가이드봉삽입공(27)에 삽입된 가이드봉(12)이 가이드봉이동공(27A)내에서 좌우로 이동하게 되므로 원하는 위치로 조정할 수 있게 된다.In order to accommodate the eccentric member 20, the eccentric member insertion groove 22 is formed in the upper butyl base 21 in the form of a recess, and the adjustment hole 26 of the adjustment bracket 24 is placed on the vertical upper portion thereof. When the screw portion 20B is exposed through the adjusting hole 26, the screw portion 20B is turned to the driver 28 so that the adjusting bracket 24 is left and right about the fastening screw 16. Since the guide rod 12 inserted into the guide rod insertion hole 27 moves left and right within the guide rod moving hole 27A, the guide rod 12 can be adjusted to a desired position.
이러한 구조의 본 고안에서 상기 편심부재 삽입홈(22)은 정방형으로 형성함이 제조공정상 바람직할 것이다. 또한 상기 조정공(26)은 가이드봉(12)의 길이방향으로 장공형태로 천공하여 상기 기저부(20A)가 원운동을 할 때 상기 나사부(20B)는 상기 조정공(26)내에서 직선운동을 할 수 있도록 한다.In the present invention of such a structure it is preferable that the eccentric member insertion groove 22 is formed in a square in the manufacturing process. In addition, the adjusting hole 26 is bored in the longitudinal direction of the guide rod 12 so that the screw portion 20B performs a linear movement in the adjusting hole 26 when the base portion 20A performs a circular motion. Do it.
이와 같은 본 고안을 적용하면, 수리작업에 필수적인 특수용도의 드라이버를 별도로 소지해야 할 필요가 전혀 없게 되고 일반적으로 흔히 쓰이는 십자 혹은 일자 드라이버를 사용할 수 있어 매우 편리하다는 효과가 있다.By applying the present invention, there is no need to carry a special purpose driver necessary for repair work at all, and there is an effect that it is very convenient to use a commonly used cross or flat head screwdriver.
