본 고안은 비디오 디스크 플레이어에 있어서, 이의 턴테이블을 캠으로 상. 하 승강시킬수 있도록 한 턴테이블 구동장치에 관한 것이다.The present invention is a video disk player, the turntable of the cam. It relates to a turntable drive that can be lowered.
종래에는 턴테이블을 구동하기 위하여 모터와 벨트를 이용하고 있으며 턴테이블의 승강을 레버와 링크장치로 승강토록하거나 와이어등을 이용하고 있었다.Conventionally, a motor and a belt are used to drive a turntable, and the lifting and lowering of the turntable is performed using a lever and a link device, or wires are used.
그러나, 이러한 종래의 것들은 구조가 매우 복잡하고 제작이 까다로울뿐만 아니라 고장율이 높았으며 턴테이블을 승강시키기 위한 승강장치의 설치공간이 필요이상으로 커져야하므로서 플레이어의 전체적인 규격이 커지는 점등의 문제점이 있었다.However, these conventional ones have a problem that the structure is very complicated and difficult to manufacture, the failure rate is high, and the installation size of the elevating device for elevating the turntable has to be larger than necessary, thereby increasing the overall size of the player.
본 고안은 종래의 이러한 문제점을 해결하기 위하여 안출한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve such a conventional problem, which will be described in detail with reference to the accompanying drawings.
즉, 비디오 디스크 플레이어의 턴테이블(2)중앙 상부에 캡스핀들(3)을 설치하고 이의 하방 지지구4)에 마그네트(5)를 설치하며 마그네트(5)의 중앙부에 전원에 의하여 극성을 갖는 자성체(6)를 설치하고 지지구(4)에는 회로기판(7)과 지지편(8)을 설치한 것에 있어서, 턴테이블(2)축(2')의 상부에 요부(9)를 형성하고 이 부위에 볼(11)을 유설시킨 고정구(10)를 설치하며, 기대(1)의 일측에 모터(12)와 벨트(15)에 의하여 회동토록 웜(14)을 형성한 풀리(13)를 설치하고 웜(14)에 치합토록 웜기어(16)를 설치하되, 평기어(17)와 일체로 형성하며 평기어(17)에는 전달기어(18)를 치합하고 전달기어(18)에는 일측에 경사부(20)를 형성하고 타측에는 기어(21)를 형성한 원판캠(19)의 기어(21)를 치합토록하여 이를 브라킷(22)에 설치하며 원판캠(19)의 경사부(20)에 턴테이블(2)축(2')이 재치토록 구성하여서 된 것으로 미설명부호 23은 디스크이다.That is, the capspindle 3 is installed at the center of the turntable 2 of the video disc player, the magnet 5 is installed at the lower support 4 thereof, and the magnetic material having a polarity by the power source is provided at the center of the magnet 5. 6) and the support 4 is provided with a circuit board 7 and a support piece 8, in which a recess 9 is formed on the top of the shaft 2 'of the turntable 2, The fastener 10 in which the ball 11 is installed is installed, and on one side of the base 1, a pulley 13 is formed in which a worm 14 is formed to rotate by the motor 12 and the belt 15. The worm gear 16 is installed on the 14 so as to be engaged, and is integrally formed with the spur gear 17. The spur gear 17 is fitted with the transmission gear 18 and the transmission gear 18 has the inclined portion 20 at one side. ) And the gear 21 of the disc cam 19 having the gear 21 formed thereon to be engaged with each other and installed on the bracket 22 and the turntable 2 on the inclined portion 20 of the disc cam 19. ) Axle (2 ') is mounted The reference numeral 23 designates a disk.
이상과 같이 구성된 본 고안은 디스크(23)를 삽입시킨 상태에서 로오딩 동작을 시키게 되면 모터(12)가 회동하여 풀리(13)와 웜(14)을 회동시키며 웜(14)에 치합된 웜기어(16)가 회동하고 이와 일체로된 평기어(17)가 회동하여 전달기어(18)를 통하여 원판캠(19)의 기어(21)를 돌려주게 됨에 따라 원판캠(19)이 회동하며 이의 경사부(20)에 재치되어 있던 턴테이블(2)이 상승하여 이의 상부에 디스크(23)가 얹히게 되는데, 이때 턴테이블(2)의 축(2')에 형성된 요부(9)에 설치된 볼(11)이 유설되어 있어 마그네트(5), 고정구(10)등은 고정된 상태에 있고 턴테이블(2)만 상승하여 로오딩 동작이 완료된다.According to the present invention configured as described above, when the loading operation is performed in the state where the disk 23 is inserted, the motor 12 rotates to rotate the pulley 13 and the worm 14, and the worm gear engaged with the worm 14 ( 16) rotates and the spur gear 17 integrally rotates to return the gear 21 of the disc cam 19 through the transmission gear 18, the disc cam 19 is rotated and its inclined portion The turntable 2 mounted on the 20 is lifted so that the disk 23 is placed on the upper part of the turntable 2. At this time, the ball 11 installed in the recess 9 formed in the shaft 2 ′ of the turntable 2 is Since the magnet 5, the fixture 10, and the like are fixed, only the turntable 2 is raised to complete the loading operation.
이러한 상태에서 자성체(6)에 전원을 공급하여 마그네트(5)에 의해 턴테이블(2)이 회동토록하며 이는 턴테이블(2)의 축(2')에 형성시킨 요부(9)와 볼(11)에 의하여 턴테이블(2)의 회동이 가능토록 한 것이고, 언로오딩시에는 상기 모터(12)를 역회전 시키면 원판캠(19)이 상기의 역동작을 하여 턴테이블(2)이 하강하게 된다.In this state, power is supplied to the magnetic body 6 so that the turntable 2 is rotated by the magnet 5 to the recesses 9 and the ball 11 formed on the shaft 2 'of the turntable 2. In this case, the turntable 2 can be rotated. When unloading, when the motor 12 is rotated in reverse, the disc cam 19 reverses the operation and the turntable 2 descends.
이상과 같은 본 고안은 원판캠(19)과 요부(9) 및 볼(11)등에 의하여 턴테이블(2)의 승강 및 회동이 간단하고 원활하며 고장율이 적고 종래에 비하여 부피가 커지지 않는 점등의 특징을 지닌 것이다.The present invention as described above is characterized by the light of the disc cam 19, the recessed part 9 and the ball 11, the lifting and rotation of the turntable 2 is simple and smooth, the failure rate is small, and the volume is not bulky as compared with the prior art. I have it.
