본 고안은 양면연속 재생형의 디스크 플레이어에 관한 것으로, 특히 디스크의 일측면의 재생이 끝나면 연속하여 디스크의 반대면을 재생시킬 수 있도록 한 양면연속 재생 디스크 플레이어에 관한 것이다.The present invention relates to a disc player of a double-sided continuous playback type, and more particularly to a double-sided continuous playback disc player to be able to play the opposite side of the disc continuously after the reproduction of one side of the disc.
종래 기술의 디스크 플레이어는 그 전형적인 예를 제 1 도에서 보인 바와같이, 디스크(1)를 로딩하는 턴테이블(2)을 갖는 턴테이블 모우터(3)에 인접하여 디스크91)의 반경방향으로 가이드축(4)이 착설되고 이에 디스크(1)를 향하는 대물렌즈(5)가 착설된 픽업 조립체(6)를 안내되게 착설한 구조로 되어 있다. 이와같은 종래 디스크 플레이어에 있어서는 픽업조립체(6)가 디스크(1)의 반경방향으로 이동하면서 디스크(1)의 면에 기록된 정보를 재생할 수 있게된 것이다.The disc player of the prior art has a guide shaft in the radial direction of the disc 91 adjacent to the turntable motor 3 having the turntable 2 for loading the disc 1, as shown in FIG. 4) is mounted and the pick-up assembly 6 in which the objective lens 5 facing the disk 1 is mounted is guided and installed. In such a conventional disc player, the pickup assembly 6 is capable of reproducing the information recorded on the surface of the disc 1 while moving in the radial direction of the disc 1.
그러나 이와같은 종래기술에 있어서는 픽업조립체(6)가 고정된 진로에서 안내이동되면서 디스크(1)의 일측면만을 재생토록 되어 있으므로 디스크(1)의 타측면을 재생코자할 경우에는 디스크(1)를 꺼내서 뒤집어 로딩시킨 후 상기 일측면 재생의 경우와 같이 픽업조립체(6)의 대물렌즈에 의하여 재생이 이루어지도록 하여야 한다. 따라서 영화와 같이 디스크의 양면에 걸쳐 정보가 기록되어 있어 연속재생을 요하는 디스크에서는 일측면의 재생후 반대면을 재생시 디스크를 수동으로 뒤집어 로딩시켜야 하는 번거로움이 있었다.However, in the prior art, since the pickup assembly 6 is guided in a fixed path, only one side of the disc 1 is to be reproduced, so that the disc 1 is to be reproduced. After taking out and loading upside down, the regeneration is to be performed by the objective lens of the pickup assembly 6 as in the case of the one-side regeneration. Therefore, the information is recorded on both sides of the disk, such as a movie, and the disc that requires continuous playback has the trouble of manually loading the disc upside down when playing the reverse side of the one side.
본 고안에 있어서는 종래의 이와같은 점을 감안하여 안출한 것으로, 디스크를 뒤집어 로딩시키지 아니하고도 디스크의 양면을 연속재생토록한 것인 바, 이를 첨부 도면 제 2 도 제 5 도에 의거하여 보다 상세히 설명하면 다음과 같다.In the present invention, in view of such a conventional point of the present invention, the two sides of the disk to be continuously played even without loading the disk upside down, which will be described in more detail on the basis of the accompanying drawings 2 and 5 Is as follows.
디스크(11)가 얹히는 턴테이블(12)에 인접하여 기판(13) 상에 "ㄷ"자형 안내레이(14)을 착설하고 이 안내레일(14)과는 일정한 거리를 두고 지지구(15)(16)로 지지되면 안내레일(14)에 평행한 안내축(17)을 착설하며, 이들 안내레일(14)과 안내축(17) 상에 픽업베이스(18)를 착설하되 픽업베이스(18)의 하측에 로울러(19)가 착설된 지지대(20)를 연장하여 로울러(19)가 안내레일(14)에서 안내되게 하고 그 대항측에는 안내측(17)에 결합되어 안내되는 안내대(21)(22)를 착설하고, 칙업베이스(18)의 일측에 래크(23)를 형성하여 구동 피니언(24)에 결합시킨 것에 있어서, 픽업베이스(18) 상에 대향된 두개의 축수(25)(26)를 착설하여 중심에 축(27)(28)을 갖는 원통형의 픽업조립체(29)를 축설하고, 이 픽업조립체(29)의 일측면에서 그 중심측으로부터 벗어난 위치에 픽업암(30)을 연장하여 디스크(11)에 직경방향 선상에 놓이는 대물렌즈(31)를 착설하며, 픽업조립체(29)의 타측면 주연에는 픽업기어(32)를 형성하여 픽업베이스(18)상에 착설한 모우터(33)의 구동기어(34)의 연결하여 서 된 구조이다.Adjacent to the turntable 12 on which the disk 11 is placed, a " c " shaped guidelay 14 is installed on the substrate 13, and the supporter 15 ( 16, a guide shaft 17 parallel to the guide rail 14 is installed, and a pickup base 18 is installed on these guide rails 14 and the guide shaft 17. Extending the support 20, the roller 19 is installed on the lower side so that the roller 19 is guided from the guide rail 14, the guide side is coupled to the guide side (17) guided on the opposite side (22) ), The rack 23 is formed on one side of the chuck-up base 18 and coupled to the drive pinion 24. The two shafts 25 and 26 opposed to the pick-up base 18 are mounted. It installs and arranges the cylindrical pick-up assembly 29 which has the shaft 27 and 28 in the center, and extends the pick-up arm 30 in the position which deviates from the center side in one side of this pick-up assembly 29, A motor 33 placed on the pick-up base 18 by forming a pick-up gear 32 on the other periphery of the pick-up assembly 29, and mounting the objective lens 31 on the screed 11 in a radial line. ) Is the structure of the drive gear 34 connected to.
이와같이 본 고안은 픽업베이스(18)가 안내레일(14)과 안내축(17)의 안내하에 래크(23)에 결합시킨 구동피니언(24)에 의하여 이동된다.As such, the present invention is moved by the drive pinion 24 in which the pickup base 18 is coupled to the rack 23 under the guide rail 14 and the guide shaft 17.
픽업베이스(18)의 축수(25)(26)에 양측의 축(27)(28)으로 착설된 원통형 픽업조립체(29)가 모우터(33)의 구동기어(34)에 의한 구동으로 이에 결합된 픽업기어(32)를 통하여 픽업암(30)이 일측위치에, 예시된 도면에서는 하측위치에, 놓이도록 회전한 후 고정된 상태에서, 픽업베이스(18)가 이동하면서 픽업암(30)의 대물렌즈(31)를 통해 디스크(11)의 일측면에 기록된 정보를 재생한다. 이와같이 디스크(11)의 일측면을 재생한 후, 일측면의 재생완료신호가 모우터(33)에 전다로디면 모우터(33)가 구동되어 구동기어(34)는 픽업기어(32)를 회전시켜 픽업 조립체(29)를 180°회전시켜 그 픽업암(30)이 디스크(11)의 외측에서 그 위치를 180°바꾸어 디스크(11)의 타측면에 픽업암(30)의 대물렌즈(31)가 향하게 되어 이 타측면을 재생하게 되는 것이다.The cylindrical pickup assembly 29 mounted on the shafts 25 and 26 of the pickup base 18 on the shafts 27 and 28 on both sides is coupled thereto by driving by the drive gear 34 of the motor 33. The pick-up arm 30 is rotated so as to lie in one position, and in the lower position in the illustrated figure, through the pick-up gear 32, and the pick-up base 18 moves while the pick-up base 18 moves. Information recorded on one side of the disc 11 is reproduced through the objective lens 31. After reproducing one side of the disk 11 as described above, when the completion signal of reproduction of one side is transferred to the motor 33, the motor 33 is driven to drive the gear 34 to rotate the pickup gear 32. The pickup assembly 29 is rotated 180 degrees so that the pick-up arm 30 changes its position 180 degrees from the outside of the disc 11 so that the objective lens 31 of the pick-up arm 30 is on the other side of the disc 11. Will be turned to play this other side.
따라서 디스크(11)의 일측면과 타측면을 연속 재생될 수 있는 것이다.Therefore, one side and the other side of the disc 11 can be continuously reproduced.
