본 발명은 디스크 플레이어에 있어서 픽업의 기울기를 조정하여 디스크 기록면과의 평행도를 맞추기 위한 픽업 기울기 조정 장치에 관한 것이다.The present invention relates to a pickup inclination adjustment device for adjusting the inclination of the pickup in the disc player to match the parallelism with the disc recording surface.

일반적으로 CDP(compact disk player)나 DVDP(digital versatile disk player)와 같이 디스크를 기록매체로 하여 정보를 기록하고 재생하는 디스크 플레이어에는, 도 1에 도시된 바와 같이, 턴테이블(2)에 안착되어 회전하는 디스크(10)에 광을 조사하고 그로부터 반사되는 광을 수광하는 픽업(12)이 구비되어 있다. 이 픽업(12)은 베이스(1)에 설치된 가이드샤프트(11)을 타고 디스크(10)의 반경방향으로 이동하면서 디스크(10)에 광을 조사하게 되는데, 이와 같이 조사된 광은 디스크(10)의 기록면에 수직으로 입사되어야만 정확한 초점의 광스폿을 형성할 수 있게 된다. 그런데 만일, 광의 입사방향이 틀어지게 되면 디스크(10)에 정확한 광스폿을 형성할 수 없게 되고, 그렇게 되면 데이터의 기록하고 재생하는데 있어서 에러가 발생할 수 있게 된다. 따라서 광스폿이 정확하게 형성되도록 하기 위해서는 상기 디스크(10)와 픽업의 평행도를 맞춰서 광이 기록면에 수직으로 입사되도록 해야 한다. 물론 상기 픽업에는 포커싱 서보가 설치되어 있어서 디스크 기록면에 광의 초점이 맞도록 동적으로 제어하는 기능이 마련되어 있으나, 조립시 디스크와 픽업의 평행도가 이미 틀어져 있으면 이를 포커싱 서보만으로 감당하기가 어려워진다. 따라서 조립시 디스크와 픽업의 수평도를 조정할 수 있는 구조가 요구되고 있다.In general, a disc player that records and plays back information using a disc as a recording medium, such as a compact disk player (CDP) or a digital versatile disk player (DVDP), is mounted on the turntable 2 and rotated as shown in FIG. A pickup 12 for irradiating light to the disk 10 and receiving light reflected therefrom is provided. The pickup 12 is irradiated with light to the disk 10 while moving in the radial direction of the disk 10 by the guide shaft 11 installed on the base 1, the light irradiated in this way is the disk 10 Only when the light is incident perpendicularly to the recording surface, the light spot of the correct focus can be formed. However, if the direction of incidence of light is misaligned, an accurate light spot cannot be formed on the disc 10, and an error may occur in recording and reproducing data. Therefore, in order for the light spot to be formed accurately, the light must be incident perpendicularly to the recording surface by matching the parallelity between the disk 10 and the pickup. Of course, the pickup is provided with a focusing servo to dynamically control the focus of the light on the disk recording surface. However, if the parallelism between the disk and the pickup is already distorted at the time of assembly, it will be difficult to handle the focusing servo alone. Therefore, there is a demand for a structure capable of adjusting the horizontality of the disk and the pickup during assembly.

본 발명은 상기의 점을 감안하여 창출된 것으로서, 조립시 디스크와 픽업의 평행도를 조정할 수 있도록 된 픽업 기울기 조정장치를 제공하는데 그 목적이 있다. SUMMARY OF THE INVENTION The present invention has been made in view of the above point, and an object thereof is to provide a pickup inclination adjusting device which is capable of adjusting the parallelism between the disk and the pickup during assembly.

상기 목적을 달성하기 위한 본 발명의 픽업 기울기 조정장치는, 픽업이 설치되는 제1베이스와, 디스크가 안착될 턴테이블이 설치되는 제2베이스와, 상기 제1,2베이스를 상호 결합시키며, 상기 제2베이스에 대한 제1베이스의 기울기를 가변시킴으로써 상기 디스크에 대한 픽업의 평행도를 조정하는 조정수단을 포함하는 것을 특징으로 한다.The pickup inclination adjusting device of the present invention for achieving the above object, the first base on which the pickup is installed, the second base on which the turntable on which the disk is to be mounted, and the first and second bases are mutually coupled to each other. And adjusting means for adjusting the parallelism of the pick-up with respect to the disc by varying the inclination of the first base with respect to the two bases.

여기서 상기 조정수단은, 상기 제1베이스에 형성된 돌기와, 상기 제2베이스에 회전가능하게 설치되며, 상기 돌기가 슬라이딩 가능하게 접촉되는 승강 궤적의 캠면이 마련된 캠부재와, 상기 제1,2베이스를 서로 접근되는 방향으로 탄성바이어스되게 결합시키는 결합부;를 포함하여서, 상기 캠부재를 회전시키면 상기 제1베이스의 돌기가 상기 캠면을 타고 슬라이딩되며 승강됨으로써 상기 제2베이스에 대한 제1베이스의 기울기가 가변되도록 구성되는 것이 바람직하다.The adjusting means may include a cam member provided with a protrusion formed on the first base, a cam member rotatably installed on the second base, and a cam surface of a lifting trajectory to which the protrusion is slidably contacted, and the first and second bases. And a coupling part configured to be elastically biased in a direction approaching each other. When the cam member is rotated, the protrusion of the first base slides on the cam surface and ascends, thereby inclining the first base with respect to the second base. It is preferably configured to be variable.

이하 첨부된 도면을 참조하면서 본 발명에 따른 바람직한 실시예를 상세히 설명하기로 한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2는 본 발명에 따른 픽업 기울기 조정장치가 채용된 디스크 플레이어의 내부구조를 나타낸다. 도면을 참조하면, 디스크 플레이어에는 픽업이 이동가능하게 설치되는 제1베이스(100) 및, 디스크가 안착될 턴테이블(101)이 설치되는 제2베 이스(200)가 마련되어 있다. 2 shows the internal structure of a disc player employing a pickup tilt adjusting device according to the present invention. Referring to the drawings, the disc player is provided with a first base 100 on which the pickup is movable and a second base 200 on which the turntable 101 on which the disc is seated is installed.

그런데 본 실시예에서는 전술한 도 1의 경우와는 달리, 픽업이 대물렌즈(121)를 탑재하여 가이드샤프트(110)를 따라 이동하는 이동광학계(120)와, 그 이동광학계(120)의 대물렌즈(121)를 통해 광을 조사하도록 제1베이스(100) 일측에 고정된 고정광학계(130)로 분리된 분리형 픽업을 예시하였다. 그러나, 본원발명을 채용함에 있어서 도 1과 같은 일체형 픽업의 경우도 마찬가지임을 미리 밝혀둔다. 즉, 이하에 설명될 본원발명은, 픽업이 장착된 제1베이스(100)와 턴테이블(101)이 장착된 제2베이스(200)의 상대적인 기울기를 조정하여 대물렌즈(121)를 통해 조사된 광이 디스크에 수직으로 입사하도록 하는 것이기 때문에, 제1베이스(100)에 일체형 픽업이 설치되든지 분리형 픽업이 설치되든지는 별 문제가 되질 않는다.However, in the present embodiment, unlike the case of FIG. 1 described above, the pickup is equipped with the objective lens 121 and the moving optical system 120 moving along the guide shaft 110, and the objective lens of the moving optical system 120 The separated pickup separated by a fixed optical system 130 fixed to one side of the first base 100 to irradiate light through 121 is illustrated. However, in adopting the present invention, it is also noted that the same applies to the case of the integrated pickup as shown in FIG. That is, the present invention to be described below, the light irradiated through the objective lens 121 by adjusting the relative inclination of the first base 100 is mounted on the pickup and the second base 200 is mounted on the turntable 101 Since the incidence is made perpendicular to the disc, it does not matter whether the integrated pickup or the separate pickup is installed in the first base 100.

참조부호 141 및 142는 각각 센터요오크와 사이드요오크를 나타내며, 참조부호 144는 마그네트, 참조부호 143은 코일로서, 이들이 만들어내는 전자기력에 의해 이동광학계(120)가 움직이게 된다.Reference numerals 141 and 142 denote center yokes and side yokes, respectively, reference numeral 144 is a magnet and reference numeral 143 is a coil, and the moving optical system 120 is moved by the electromagnetic force generated by them.

한편, 상기 제1,2베이스(100)(200)는 다음과 같은 조정수단에 의해 상호 결합되어 기울기가 조정된다. 먼저 상기 제1베이스(100)의 이면에는 도 2 및 도 3에 도시된 바와 같이 돌기(100a)가 돌출 형성되어 있다. 그리고 이 돌기(100a)는 제2베이스(200)에 회전가능하게 설치된 캠부재(153)의 캠면(153a)에 접촉된다. 이 캠면(153a)은 원주를 따라 점차 높아졌다가 다시 낮아지는 승강 궤적으로 이루어져 있어서, 상기 캠부재(153)를 회전시키면 상기 돌기(100a)가 캠면(153a)을 타고 슬 라이딩하면서 승강하게 된다. 또한 상기 캠부재(153)에는 상기 제1베이스(100)의 관통공(100b)을 통해 삽입되는 보스부(153b)가 형성되어 있어서, 이 보스부(153b) 선단에 스크류(151)가 와셔(154)를 개재하여 체결된다. 그리고 상기 보스부(153b) 외곽에는 스프링(152)이 설치되어서 상기 와셔(154)와 상기 관통공(100b) 가장자리부 사이에 양단이 지지되어 있다. 따라서 이 스프링(152)은 제1베이스(100)가 제2베이스(200)에 접근되는 방향으로 탄성력을 제공하게 되며, 상기 돌기(100a)와 캠면(153a)의 접촉에 의해 제1,2베이스(100)(200)간의 간격이 유지되는 것이다.Meanwhile, the first and second bases 100 and 200 are coupled to each other by the following adjustment means to adjust the inclination. First, as shown in FIGS. 2 and 3, the protrusion 100a protrudes from the rear surface of the first base 100. The protrusion 100a is in contact with the cam surface 153a of the cam member 153 rotatably installed on the second base 200. The cam surface 153a is formed by a lifting trajectory gradually increasing along the circumference and then lowering again. When the cam member 153 is rotated, the protrusion 100a moves up and down while riding on the cam surface 153a. In addition, the cam member 153 is formed with a boss portion 153b inserted through the through hole 100b of the first base 100, and a screw 151 is disposed at the tip of the boss portion 153b. 154 is fastened through. A spring 152 is installed outside the boss 153b to support both ends between the washer 154 and the edge of the through hole 100b. Accordingly, the spring 152 provides an elastic force in the direction in which the first base 100 approaches the second base 200, and the first and second bases are contacted by the protrusion 100a and the cam surface 153a. The interval between (100) and (200) is maintained.

상기 구성에 있어서, 턴테이블(101)에 안착된 디스크(미도시)와 픽업(120,130)의 평행도를 조정하고자 할 경우에는, 도 4a 및 도 4b에 도시된 바와 같이 상기 캠부재(153)를 회전시킨다. 이에 따라 상기 제1베이스(100)가 상기 캠면(153a)의 승강 궤적을 따라 승강하면서 제2베이스(200)에 대한 기울기가 변하게 되며, 이로써 디스크에 대한 픽업의 평행도가 조정되는 것이다. 그리고 이와 같은 조정구조는 도 2에 도시된 바와 같이 모두 3개소에 설치되어 있다. 따라서, 이들을 각각 조정하면서 전후좌우 각 방향에 대한 기울기를 조정할 수 있다.In the above configuration, in order to adjust the parallelism of the disk (not shown) mounted on the turntable 101 and the pickups 120 and 130, the cam member 153 is rotated as shown in FIGS. 4A and 4B. . Accordingly, as the first base 100 moves up and down along the lifting trajectory of the cam surface 153a, the inclination with respect to the second base 200 is changed, thereby adjusting the parallelism of the pickup to the disc. And this adjustment structure is provided in all three places as shown in FIG. Therefore, the inclination with respect to each of the front, back, left, and right directions can be adjusted while adjusting each of these.

따라서 가공오차나 조립오차 등에 의해 턴테이블에 안착되는 디스크와 픽업간의 평행도가 틀어지더라도 상기와 같은 픽업 기울기 조정장치로 그 오차를 보정할 수 있는 것이다.Therefore, even if the parallelism between the disk and the pickup seated on the turntable is changed due to machining error or assembly error, the error can be corrected by the pickup tilt adjustment device as described above.

상술한 바와 같이 본 발명에 따른 픽업 기울기 조정장치에 의하면, 조립시 턴테이블에 안착된 디스크와 픽업간의 평행도를 맞출 수 있기 때문에, 가공오차나 조립오차에 의한 평행도 오차를 보정할 수 있으며, 그에 따라 디스크의 기록 재생 기능의 신뢰성을 높여주게 된다.As described above, according to the pickup inclination adjusting device according to the present invention, since the parallelism between the disk and the pickup seated on the turntable at the time of assembly can be matched, the parallelism error due to the machining error or the assembly error can be corrected, and accordingly the disk This improves the reliability of the recording / playback function.

본 발명은 상기에 설명되고 도면에 예시된 것에 의해 한정되는 것은 아니며, 다음에 기재되는 청구의 범위 내에서 더 많은 변형 및 변용예가 가능한 것임은 물론이다.It is to be understood that the invention is not limited to that described above and illustrated in the drawings, and that more modifications and variations are possible within the scope of the following claims.
