Description

디스크 고정장치Disc stopper

제 1 도는 종래의 디스크 고정장치의 종단면도1 is a longitudinal cross-sectional view of a conventional disc anchor.

제 2 도는 본 고안의 요부분리 사시도2 is a partial perspective view of the present invention

제 3 도는 본 고안의 작용 상태의 종단면도3 is a longitudinal sectional view of an operating state of the present invention

본고안은 비디오 디스크 플레이어에서, 디스크 원판위에 고정된 디스크의 위치가 편심이 되지 않도록 디스크를 중심잡기 원통에 끼우고 고정덮개를 덮으면 중심잡기 원통 외면의 경사면에 의해서 디스크 중심이 일치되게 고정시키는 디스크 고정장치의 구성에 관한 것이다.In this video, the disc is fixed in the video disc player so that the position of the disc fixed on the disc disk is not eccentric and the disc is fixed to the center of the cylinder by the inclined surface of the outer surface of the centering cylinder. It relates to the configuration of the device.

종래에는 제 1 도와 같이 비디오 디스크 플레이어에서, 디스크 회전시에 편심이 되지 않도록 모터축(26)에 축설된 회전원판(21)위에 고정된 외면이 경사진 디스크 중심잡기 원통체(22)를 스프링 (23)에 탄지한 것 위에 고정덮개(24)로 디스크(25)를 덮어서된 디스크 고정장치가 있으나 이는 디스크가 가볍고 스프링의 탄성력에 의한 원통체 경사면 때문에 디스크가 회전판 위에 제대로 밀착되지 않아 무거운 덮개로 눌려야만 되었고, 중심잡기의 장치도 복잡했던 문제점이 있었다.Conventionally, in a video disc player as in the first diagram, a disc centering cylindrical body 22 having an inclined outer surface fixed on a rotating disc 21 arranged on a motor shaft 26 so as not to be eccentric when the disc is rotated ( 23) there is a disk fixing device that covers the disk 25 with the fixing cover 24 on the hard one, but the disk is not pressed against the rotating plate because of the light weight of the cylinder and the inclined surface of the cylinder due to the elastic force of the spring. It was a must, and the centering device had a complex problem.

본 고안은 이와 같은 문제점을 해결하기 위하여 외면이 경사진 중심잡기 원통체의 자체탄성력에 의하여 끼워진 디스크가 편심되지 않게 고정하였으며 그 구성도 간단하게한 것이다.In order to solve the above problems, the present invention fixed the disc inserted by the self-elastic force of the centering cylinder with the inclined outer surface so as not to be eccentric and to simplify the configuration thereof.

본 고안 장치의 구성은 별첨도와 같이, 디스크 원판(1) 상면에 형성된 원주홈(2)에 지지체(3)에 씌워진 중심잡기 원통체(4)를 나사(5) 고정하고 중심잡기 원통체(4)는 다수개의 조각편(4')으로 이루어지고 디스크 원판(1) 하면에 받쳐진 받침판(6)과 디스크 원판(1) 그리고 지지체(3)와 중심잡기 원통체(4) 중앙에 모터축(7)이 축설되고 축단부(7')는 고정덮개(8) 중앙홈(9)에 끼워서 누름판(10)으로 고정하여서된 것이다.The structure of the device of the present invention is, as shown in the appended drawings, the centering cylindrical body 4, which is covered by the support body 3, on the circumferential groove 2 formed on the upper surface of the disc disc 1, and the screw 5 and the centering cylindrical body 4 ) Is composed of a plurality of pieces (4 ') and the support plate 6 and the disk disk (1) supported on the lower surface of the disk disk (1) and the motor shaft (7) in the center of the support (3) and the centering cylinder (4) ) And the shaft end portion 7 'is fixed to the pressing plate 10 by being inserted into the center cover 9 of the fixing cover 8.

미설명부호 11 : 중심잡기 원통체 고정판, 12 : 디스크, 13 : 베어링, 14 : 고정 덮개의 축, 15 : 누름판 고정용 E링 이다.Reference numeral 11: centering cylinder holding plate, 12: disk, 13: bearing, 14: shaft of the fixing cover, 15: E-ring for fixing the pressing plate.

본 고안 장치의 작용 효과는, 제 3 도와 같이 중심잡기 원통체(4)의 다수개의 조각편(4')들이 동심원을 이루고 있으므로 디스크(12) 통공 주면이 밀착되어 꼭 끼게됨과 동시에 중심잡기 원통체(4)의 외면은 경사져있으므로 이 경사면과 모터측(7) 단부(7')는 고정덮개(8)이 홈(9)에 끼워져서 중심이 잡혀있는 고정덮개(8)에 의하여 디스크(12)는 편심되지 않고 고정되는 것이다.The working effect of the device of the present invention is that the plurality of pieces 4 'of the centering cylindrical body 4 are concentric, as shown in the third diagram. Since the outer surface of 4) is inclined, the inclined surface and the motor side 7 end 7 'are fixed to the disk 12 by the fixing cover 8 centered by the fixing cover 8 being inserted into the groove 9. It is fixed without being eccentric.

이 상태에서 모터축(7)은 디스크 원판(1)과 디스크(12) 그리고 고정덮개(8)와 같이 회전하되 베어링(13)은 축(14)을 중심으로 고정덮개(8)와 같이 편심없이 회전하는 것이다.In this state, the motor shaft 7 rotates as the disc disc 1, the disc 12 and the fixed cover 8, but the bearing 13 is free from eccentricity like the fixed cover 8 around the shaft 14 To rotate.

이와같이 본 고안은 스프링없이 중심잡기 원통체의 자체 탄성력에 의해 디스크를 고정하게 되므로 구성이 간단해지게 되어 제조 및 조립하기도 용이하게 된 것이다.In this way, the present invention is fixed to the disk by the self-elastic force of the centering cylindrical body without a spring, the configuration becomes simple and easy to manufacture and assemble.
