3 : 픽업 4 : 압축스프링3: pickup 4: compression spring

본 고안은 콤팩트 디스크 플레이어의 동력전달기어 백래시(back lash)방지장치에 관한 것으로, 특히 레이저 픽업의 신속하고 오차없는 이동을 가할 수 있게 하고 외부 충격등으로 인한 레이저 픽업의 CD(콤팩트 디스크)정보면 트랙 이탈로 인한 음 건너뜀 현상을 방지하고자한 동력전달기어 백래시 방지장치에 관한 것이다.The present invention relates to a power transmission gear backlash prevention device of a compact disc player. In particular, the CD (compact disc) information surface of the laser pickup can be quickly and error-freely moved by an external shock and the like. The present invention relates to a power transmission gear backlash prevention device for preventing a sound skip caused by a track departure.

통상의 콤팩트 디스크 플레이어는 구동모터의 회전에 의하여 회전하는 구동피니언에 랙이 맞물려 직선 이동함에 따라 레이저 픽업이 직선 이동하면서 CD에 기록된 음을 재생하도록 되어 있다.A typical compact disc player is adapted to reproduce a sound recorded on a CD while the laser pickup moves linearly as the rack is linearly engaged with the driving pinion rotated by the rotation of the drive motor.

그러나 종래에는 동력전달기어의 자체 정밀도, 조립시의 공차, 동작시의 마모등으로 백래시가 발생하고 이로인해 동력전달의 오차 및 소음발생과 외부 충격등으로 인하여 레이저 픽업이 CD정보면 트랙을 이탈하여 CD연주시 음 건너뜀 현상이 발생하는 것이었다.However, in the related art, backlash occurs due to self-accuracy of power transmission gear, tolerance during assembly, and wear in operation, which causes laser pickup to deviate from CD track track due to power transmission error, noise, and external shock. The sound skipped when playing CD.

본 고안은 상기한 바와같은 종래의 결합을 해소하기 위하여 안출한 것으로, 이를 첨부한 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is devised to solve the conventional combination as described above, it will be described in detail by the accompanying drawings as follows.

제1도 내지 제4도에 도시한 바와같이, 구동피니언(1)에 맞물린 랙(2)이 직선 이동하면 랙(2)이 고정되어진 픽업(3)이 직선이동하는 것에 있어서, 상기 랙((2)의 상면에 돌기(2a)를 형성하고 랙(2)의 상면에는 또 하나의 랙(2')을 그의 양측 삽입공(2'a)에 상기 돌기(2a)가 삽입됨과 아울러 슬라이드되게 결합하여, 랙(2)(2')의 기어부가 구동피니언(1)에 맞물리게 하며, 하부 랙(2')의 중간공(2'c) 일측에 돌기(2'b)를 형성하고 하부랙(2)에 형성한 돌기(2b)를 중간공(2'c)의 상측으로 돌출시켜 돌기(2b)(2'b)사이에는 상부 랙(2')을 일측으로 탄력지지하는 압축스프링(4)을 설치하여서된 것이다.As shown in FIGS. 1 to 4, when the rack 2 engaged with the drive pinion 1 moves linearly, the pickup 3 to which the rack 2 is fixed moves linearly. A protrusion 2a is formed on the upper surface of 2), and another rack 2 'is inserted on both sides of the insertion hole 2'a on the upper surface of the rack 2, and the protrusion 2a is inserted and slidably coupled. Thus, the gear portion of the rack (2) (2 ') is engaged with the drive pinion (1), forming a projection (2' b) on one side of the middle hole (2 'c) of the lower rack (2') and the lower rack ( Compression spring (4) for protruding the projection (2b) formed in the 2) to the upper side of the intermediate hole (2 'c) to elastically support the upper rack (2') to one side between the projection (2b) (2'b) By installing it.

이와같이된 본 고안은 랙(2) 위에 또 하나의 랙(2') 이 일정간격 만큼 미끄럼 유동되게 결합하고 각 랙 (2)(2')이 압축스프링(4)에 의하여 서로 대향되게 밀리도록 탄력지지 지지되어 있어 각 랙(2)(2')이 압축스프링(4)에 의하여 서로 대향되게 밀리도록 탄력지지되어 있어 각 랙(2)(2')의 이빨이 구동피니언(1)의 이빨에 탄력적으로 밀착되므로 갭이 없어져 백래시가 방지된다.In this way, the present invention combines another rack 2 'on the rack 2 so as to be slidably flown by a predetermined interval, and each rack 2, 2' is elastically pushed against each other by the compression spring 4. It is supported so that each rack (2) (2 ') is elastically supported so as to be pushed against each other by the compression spring (4) so that the teeth of each rack (2) (2') to the teeth of the drive pinion (1) The elastic close contact eliminates the gap and prevents backlash.

이상에서 설명한 바와같은 본 고안의 장치를 적용하게 되면 백래시가 방지되어 레이저 픽업이 신속 정확하게 이동되므로, 콤팩트 디스크의 트랙을 정확하게 서어치할 수 있고, 외부의 충격 및 진동등에 의한 픽업의 트랙이탈을 방지하여 연주시 음 건너뜀 현상이 배재된다.Applying the device of the present invention as described above, backlash is prevented and the laser pickup is moved quickly and accurately, so that the track of the compact disc can be accurately searched, and the track of the pickup due to external shock and vibration is prevented. The note skipping phenomenon is eliminated when playing.
