Description

광 픽업의 파손 방지 구조Breakage prevention structure of optical pickup

본 고안은 광 디스크 플레이어(Optical Disc Player)에 관한 것으로, 특히 디스크상에 기록된 정보를 재생하거나 새로운 정보를 기록하는 광 픽업(Photo Pick-up)의 파손 방지 구조에 관한 것이다.The present invention relates to an optical disc player, and more particularly, to a structure of preventing damage of an optical pick-up, which reproduces information recorded on a disc or records new information.

일반적으로 광 디스크 플레이어의 광 픽업은, 광 디스크인 콤팩트 디스크(CD: Compact Disc) 또는 디지털 비디오 디스크(DVD: Digital Video Disc)의 기록면에 형성된 피트에 광 픽업에서 레이저 빔을 발사하여 기록을 수행하고, 기록면에서 반사된 빛의 증감을 수광소자가 받아서 전기적 신호로 바꾸어 판독하는 장치이며, 이러한 광 픽업을 디스크의 반경 방향으로 이송시키도록 구성된다.In general, an optical pickup of an optical disc player performs recording by firing a laser beam from an optical pickup on a pit formed on a recording surface of a compact disc (CD) or a digital video disc (DVD) which is an optical disc. In addition, the light receiving element receives the increase and decrease of the light reflected from the recording surface, and converts it into an electrical signal for reading. The optical pickup is configured to transfer the optical pickup in the radial direction of the disc.

이러한 광 디스크 플레이어는 도 1에 도시된 바와 같이 중앙이 개구된 메인 섀시(10)가 구성되고, 상기 메인 섀시(10)에 끼워 안착되는 픽업 베이스(20)가 구성되며 상기 픽업 베이스(20)에 결합되어 작동하는 광 픽업(30)이 구성되고, 상기 광 픽업(30)의 상부에는 척커버(40)가 구성된다.As shown in FIG. 1, the optical disc player includes a main chassis 10 having a central opening, a pickup base 20 fitted into the main chassis 10, and mounted on the pickup base 20. The optical pickup 30 is operated in combination, and the chuck cover 40 is configured on the optical pickup 30.

상기 메인섀시(10)는 외곽에 일체로 본체와 결합할 수 있는 고정편(11)이 구성되고 중앙이 개방된 일측에 픽업 베이스(20)와 결합할 수 있는 걸림편(12)이 구성된다.The main chassis 10 has a fixing piece 11 that can be integrally coupled to the main body on the outer side, and a locking piece 12 that can be combined with the pickup base 20 on one side of which the center is open.

상기 광 픽업(30)은 중앙이 개방된 베이스 플레이트의 양측에 이송주축(31)과 이송부축(32)이 서로 평행하게 고정되고, 광 픽업(30)을 중앙에 수용한 홀더(33)가 상기 이송주축(31)과 이송부축(32)을 따라 안내되어 이송하도록 장착되며, 상기 이송주축(31)과 연결된 홀더(33)의 일측 저면에는 길이 방향으로 랙기어(미도시)를 구비한 작동부재(미도시)가 일체로 체결되며, 상기 랙기어(미도시)가 왕복 운동할 수 있도록 동력을 전달하는 구동부(미도시)가 랙기어(미도시)의 일측에 구성된다.The optical pickup 30 has a feed spindle 31 and a feed shaft 32 fixed in parallel to both sides of a base plate having an open center, and a holder 33 having the optical pickup 30 at the center thereof. An actuating member having a rack gear (not shown) in a longitudinal direction on one bottom surface of the holder 33 connected to the feed spindle 31 and guided along the feed spindle 31 and the feed shaft 32. (Not shown) is integrally fastened, and a driving unit (not shown) for transmitting power to reciprocate the rack gear (not shown) is configured on one side of the rack gear (not shown).

상기 척커버(40)는 메인섀시(10)에 안착되어 광 픽업(30)을 수용하고 디스크(34)가 회전할 수 있는 공간을 구성한다.The chuck cover 40 is mounted on the main chassis 10 to accommodate the optical pickup 30 and constitute a space in which the disk 34 can rotate.

그런데 상기와 같이 구성된 메인섀시(10)와 척커버(40)의 결합구조는 메인섀시(10) 외곽의 공간이 외부로 노출되어 있기 때문에 사용자의 부주의로 인해 드라이버(D)와 같은 공구가 아무런 간섭없이 메인섀시(10) 내부에 있는 부품을 건드릴 수 있어 미세한 충격에도 민감한 반응을 보이는 픽업부 및 구동시스템을 건드려 파손시키는 문제점이 있었다.However, since the structure of the main chassis 10 and the chuck cover 40 configured as described above is exposed to the outside of the main chassis 10, tools such as the driver D have no interference due to user's carelessness. There is a problem that can touch the parts inside the main chassis 10 without touching the pick-up and the drive system showing a sensitive reaction even to the minute impact.

이에 본 고안은 상술한 바와 같은 종래의 제반 결함을 감안하여 이루어진 것으로, 그 목적은 시스템주요부인 픽업부 및 구동시스템등을 건드려 파손시키는 것을 방지하는 광 픽업의 파손 방지 구조를 제공함에 있다.Accordingly, the present invention has been made in view of the above-mentioned general defects, and its object is to provide a damage preventing structure of the optical pickup which prevents damage to the pick-up part and the driving system, which are the main parts of the system, from being damaged.

이러한 목적을 달성하기 위한 본 고안은 본체에 고정되도록 전.후방 양측에 고정편이 구비된 메인섀시의 구조에 있어서, 상기 각 고정편의 내측으로 소정간격 이격된 위치에 걸림돌기를 구성함을 특징으로 하는 것이다.The present invention for achieving the above object is characterized in that in the structure of the main chassis provided with fixing pieces on both sides of the front and rear to be fixed to the main body, to constitute a locking projection at a position spaced a predetermined interval inside the fixing pieces. .
