본 고안은 광디스크 플레이어의 디스크 로딩 및 픽업 슬라이딩 장치에 관한 것으로, 특히 하나의 구동모터를 이용하여 광디스크의 로딩운동과 픽업의 슬라이딩 운동이 이루어지도록 함으로써 광디스크 플레이어의 제조원가를 절감할 수 있고, 집약적인 부품배치와 설계가 가능하게 되도록 한 광디스크 플레이어의 디스크 로딩 및 픽업 슬라이딩 장치에 관한 것이다.The present invention relates to a disc loading and pick-up sliding device of an optical disc player. In particular, by using a single drive motor, the loading movement of the optical disc and the sliding movement of the pick-up can be performed, thereby reducing the manufacturing cost of the optical disc player and intensive parts. Disc loading and pickup sliding device of the optical disc player to enable the arrangement and design.
종래 광디스크 플레이어에 있어서는 디스크 로딩 및 언로딩에 관련된 구동시스템과 픽업의 슬라이딩 운동에 관련된 구동시스템이 각각 독립적을 구성되어 있고, 이들이 전기적인 신호수단으로 상호 제어되어 디스크 로딩 후 픽업의 슬라이딩 운동이 이루어지고, 픽업의 슬라이딩 운동 후에 디스크의 언로딩이 이루어질 수 있도록 되어 있다.In the conventional optical disc player, the driving system related to the disk loading and unloading and the driving system related to the sliding motion of the pickup are configured independently, and they are mutually controlled by electrical signal means, so that the sliding movement of the pickup is performed after the disk loading. In this case, the disc can be unloaded after the sliding movement of the pickup.
그러나 종래 기술의 광디스크 플레어는 디스크 로딩 및 픽업 슬라이딩에 관련된 구동시스템이 각각 독립적으로 구성되어 상대적으로 제조원가가 많이 소요되고, 전체 구성을 집약적으로 배치 및 설계할 수 없는 문제점이 있었다.However, the optical disc flare of the prior art has a problem in that the driving system related to the disk loading and the pickup sliding are independently configured, which requires a relatively large manufacturing cost, and the overall configuration cannot be intensively arranged and designed.
본 고안의 목적은, 하나의 구동모터를 이용하여 광디스크의 로딩 및 언로딩과, 픽업의 슬라이딩 운동이 이루어지도록 함으로써 원가절감과 전체 구성의 집약적인 설계와 배치가 가능하도록 한 광디스크 플레이어의 디스크 로딩 및 픽업 슬라이딩 장치를 제공하려는 것이다.An object of the present invention is to load and unload an optical disc using a single drive motor, and to perform a sliding movement of a pickup, thereby loading a disc of an optical disc player, which enables cost reduction and intensive design and arrangement of the overall configuration. It is to provide a pickup sliding device.
이하 본 고안에 의한 광디스크 플레이어의 디스크 로딩 및 픽업 슬라이딩 장치를 첨부도면에 도시한 실시예에 따라서 상세히 설명한다.Hereinafter, a disc loading and pickup sliding device of an optical disc player according to the present invention will be described in detail according to an embodiment shown in the accompanying drawings.
제1도에 도시한 바와 같이, 광디스크(1)가 얹혀지는 턴테이블(2)에 인접하여 두개의 평행한 안내레일(3)(3*)이 배설되고 이에 베이스(도시되지 않음)의 개방부(4) 범위에서 이동하는 픽업(5)이 착설되며, 픽업(5)의 일측에는 픽업래크(6)가 착설되고, 이에 인접하여 모터(7)가 착설되며, 이에 인접한 위치에 트레이(도시되지 않음)에서 연장된 기다란 트레이래크(8)가 배설되어 있다.As shown in FIG. 1, two parallel guide rails 3 (3 *) are disposed adjacent to the turntable 2 on which the optical disc 1 is placed, and thus the opening of the base (not shown) ( 4) a pickup 5 moving in a range is installed, and a pickup rack 6 is installed at one side of the pickup 5, and a motor 7 is installed adjacent thereto, and a tray (not shown) in a position adjacent thereto. Elongated tray rack 8 extending from
상기 픽업래크(6)에는 정위치에서 회전되는 픽업구동기어(9)가 맞물려지며, 모터(7)는, 이 모터(7)의 축에 고전된 모터폴리(7a)에는 정위치에는 회전되며 트레이구동기어(12)와 동축으로 된 풀리(11)가 벨트(10)로 연결되어 있다.The pickup rack 6 is engaged with the pickup drive gear 9 which is rotated at the correct position. The motor 7 is rotated at the correct position by the motor pulley 7a which is subjected to the shaft of the motor 7. A pulley 11 coaxial with the drive gear 12 is connected by a belt 10.
상기 픽업구동기어(9)와 구동기어(12)의 사이에는, 일측가장자리에는 상기 구동기어(12)와 맞물리는 트레이 구동용 제1래크(13)가 형성되고, 타측 가장자리에는 픽업구동기어(9)에 맞물리는 픽업구동용 제2래크(14)와 디스크의 로딩동작중에 픽업구동기어(9)가 위치되는 결치부(15)가 각각 부분적으로 형성된 중계부재(16)가 배설되어 있다.Between the pick-up driving gear 9 and the drive gear 12, a tray driving first rack 13 to be engaged with the drive gear 12 is formed at one edge, the pick-up driving gear 9 at the other edge And a relay member 16, each of which has a second rack 14 for pick-up driving and a engaging portion 15 in which the pick-up driving gear 9 is positioned during the loading operation of the disk.
중계부재(16)의 일측부에는 구동기어(12)에서 트레이 언로딩방향으로 이격되어 트레이구동용 제1래크(13)와 맞물릴 수 있는 위치에 트레이구동기어(17)이 설치되어 소기어(19)와 대기어(20)를 가지는 2단기어(18)을 통하여 트레이래크(8)에 맞물려진다.One side of the relay member 16 is provided with a tray driving gear 17 at a position that is spaced apart from the driving gear 12 in the tray unloading direction so as to be engaged with the first rack 13 for driving the tray. It is engaged with the tray rack 8 through the second gear 18 having the 19 and the standby gear 20.
즉, 트레이구동기어(17)는 2단기어(18)의 소기어(19)에 맞물리고, 트레이래크(8)는 대기어(20)에 맞물리는 것이다.That is, the tray driving gear 17 meshes with the small gear 19 of the second gear 18, and the tray rack 8 meshes with the atmospheric gear 20.
이와 같이 구성된 본 고안의 광디스크 플레이어의 디스크 로딩 및 픽업 슬라이딩 장치의 작동상태를 제2도 내지 제5도에 따라서 설명한다.The operation state of the disc loading and pickup sliding device of the optical disc player of the present invention configured as described above will be described with reference to FIGS.
제2도는 디스크 로딩이 시작되기 직전의 상태(언로딩 완료된 상태)를 도시하는 것으로, 트레이래크(8)는 전방(제2도의 윗부분)에 위치하고, 중계부재(16)도 전방으로 이동되어 픽업(5)의 픽업래크(6)와 맞물리는 픽업 구동기어(9)는 중계부재(16)의 결치부(15) 끝부분에 인접하여 위치하며, 구동기어(12)는 중계부재(16)의 트레이구동용 제1래크(13)의 후단부에 맞물려진 상태로 된다.FIG. 2 shows a state (unloaded state) just before disc loading starts, the tray 8 is located in front (upper part in FIG. 2), and the relay member 16 is also moved forward and picked up. The pickup drive gear 9 which meshes with the pickup rack 6 of (5) is located adjacent to the end of the attachment part 15 of the relay member 16, and the drive gear 12 is The rear end of the tray driving first rack 13 is engaged.
이 상태에서 디스크의 로딩모드로 되면, 모터(7)가 구동되어 모터풀리(7a)에 벨트(10)와 풀리(11)로 연동되는 구동기어(12)가 시계방향으로 회전하게 되고, 이 구동기어(12)에 제2래크(14)가 맞물려 있는 중계부재(16)는 제2도의 화살표 "A"방향으로 이동하게 된다.In this state, when the disk is in the loading mode, the motor 7 is driven so that the drive gear 12 interlocked with the belt 10 and the pulley 11 on the motor pulley 7a rotates clockwise. The relay member 16, in which the second rack 14 is engaged with the gear 12, moves in the direction of arrow " A "
이때, 중계부재(16)의 제1래크(13)에 맞물려 있는 트레이구동기어(17)가 시계방향으로 회전하게 되고 이 트레이구동기어(17)의 회전력은 소기어(19)와 이 소기어(19)와 동축으로 된 대기어(20)를 통하여 트레이래크(8)에 전달되므로 트래이래크(8)는 로딩방향으로 빠르게 이동하게 되고, 이에 따라 광디스크(1)는 트래이래크(8)와 결합되어 있는 트레이(도시되지 않음)에 얹혀진 상태에서 제2도의 화살표 "A"방향으로 로딩되기 시작한다.At this time, the tray driving gear 17 engaged with the first rack 13 of the relay member 16 rotates clockwise, and the rotational force of the tray driving gear 17 is the small gear 19 and the small gear ( Since the tray rack 8 is transferred to the tray rack 8 through the coaxial gear 20, the track rack 8 moves quickly in the loading direction, and thus the optical disc 1 is moved to the tray rack 8. Loaded in the direction of arrow "A" of FIG.
제3도는 로딩중의 상태를 도시하는 것으로, 픽업구동기어(9)는 아직 결치부(15)의 중간부분에 위치하고 있다.3 shows a state of loading, and the pickup drive gear 9 is still located in the middle of the engagement portion 15.
이러한 상태로 로딩이 계속 진행되어 제4도와 같이 로딩이 완료되면, 구동기어(12)는 제1래크(13)의 대략 중간부에 위치하게 되고, 픽업구동기어(9)는 비로소 픽업구동용 제2래크(14)의 로딩방향 선단부에 맞물리게 되며, 트레이구동기어(17)는 제1래크(13)의 로딩 방향 후단부에서 이탈되어 더이상 로딩동작이 이루어지지 않게 됨과 아울러 픽업(5)의 슬라이딩 시작 상태로 된다.When the loading is continued in this state and the loading is completed as shown in FIG. 4, the drive gear 12 is positioned at the substantially middle portion of the first rack 13, and the pickup drive gear 9 is finally used for the pickup drive agent. 2 rack 14 is engaged with the loading direction leading end, the tray drive gear 17 is released from the rear end of the loading direction of the first rack 13 no longer the loading operation and the sliding start of the pickup (5) It is in a state.
이때, 광디스트(1)는 그 중심이 턴테이블(2)의 중심에 일치하는 상태로 되어 안착된다.At this time, the optical disk 1 is seated with its center coinciding with the center of the turntable 2.
이후 모터(7)와 구동기어(12)에 의한 중계부재(16)의 동작은 픽업구동용 제2래크(14)와 픽업구동기어(9)를 통하여 픽업래크(6)에만 전달되며, 픽업래크(6)가 제5도의 화살표 "B"방향으로 이동하여 픽업(5)의 슬라이딩 하면서 광디스크(1)에 기록된 정보를 판독하게 된다.Thereafter, the operation of the relay member 16 by the motor 7 and the drive gear 12 is transmitted only to the pickup rack 6 through the second rack 14 and the pickup drive gear 9 for pickup. 6 moves in the direction of arrow " B " in FIG. 5 to slide the pickup 5 to read the information recorded on the optical disc 1;
이러한 로딩 및 슬라이딩과정은 광디스크(1)으 언로딩시에 역순으로 행하여 진다.This loading and sliding process is performed in the reverse order when the optical disc 1 is unloaded.
이상과 같이 본 고안에 의하면 하나의 구동모터를 이용하여 광디스크를 로딩 및 언로딩과, 픽업의 슬라이딩 운동을 수행하는 것이므로 종래 기술에 비하여 제조원가를 절감할 수 있으며, 집약적인 설계와 부품의 배치를 가능하게 하는 효과가 있는 것이다.As described above, according to the present invention, since one drive motor is used to load and unload an optical disc and perform a sliding movement of the pickup, manufacturing cost can be reduced compared to the prior art, and intensive design and arrangement of parts are possible. It is effective to make.
