Description

디스크 고정장치Disc stopper

제1도는 종래의 디스크 고정장치의 종단면도.1 is a longitudinal sectional view of a conventional disc anchor.

제2도는 본 고안의 요부 분리 단면도.2 is a cross-sectional view of main parts of the present invention.

제3도는 본 고안의 작용 상태의 종단면도.Figure 3 is a longitudinal cross-sectional view of the working state of the present invention.

본 고안은 비디오 디스크 플레이어에서, 디스크 원판 위에 고정된 디스크의 위치가 편심이 되지 않도록 고정덮개를 중심잡기 원통체에 끼우면 중심잡기 원통체는 디스크에 밀착되어 디스크 중심이 일치되게 고정시키는 디스크 고정장치의 구성에 관한 것이다. 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 것위에 고정덮개(24)를 덮어서된 디스크 고정장치가 있으나 이는 디스크(25)가 가볍기 때문에 스프링의 탄성력과 원통체 경사면 때문에 디스크가 회전원판 위에 제대로 밀착되지 않아 무거운 덮개로 눌러야만 되었고 중심잡기의 장치도 복잡해졌던 문제점이 있었다.The present invention is a disc fixing device in a video disc player in which the fixing cover is placed on the centering cylinder so that the position of the disc fixed on the disc disc is not eccentric. It is about configuration. Conventionally, in the video disc player as in the first diagram, the disc centering cylinder 22 having an inclined outer surface fixed on the rotating disc 21 arranged on the motor shaft 26 is spring-loaded so as not to be eccentric when the disc rotates. 23) there is a disk fixing device that covers the fixing cover 24 on the hard one, but because the disk 25 is light, the disk is not pressed against the rotating disk because of the elastic force of the spring and the cylindrical inclined surface. There was a problem that the centering device became complicated.

본 고안은 이와 같은 문제점을 해결하기 위하여 중심잡기 원통체에 고정덮개만을 끼워서 디스크를 편심되지 않게 고정하였으며 그 구성도 간단하게 한 것이다.In order to solve this problem, the present invention inserts only a fixed cover into the centering cylinder to fix the disc so as not to be eccentric and to simplify the configuration thereof.

본 고안 장치의 구성은 별첨도와 같이, 모터축(15)에 축설된 디스크원판(1)의 상축요홈(2)에 나사고정된 중심잡기 원통체(3)는 다수개의 조각편(3')으로 이루지며 그 외면 상측에 돌출부(4)를 형성하고, 누름판(5)과 결합된 하측이 원뿔대 모양의 고정덮개(6)의 하측홈(14)에 모터축(15)이 끼워짐과 동시에 고정덮개(6)가 중심잡기 원통체(3) 내부공간에 끼워져서된 것이다.The structure of the device of the present invention is, as shown in the appended drawings, the centering cylindrical body (3) screwed to the upper shaft groove (2) of the disk disc (1) arranged on the motor shaft (15) consists of a plurality of pieces (3 '). The protrusion 4 is formed on the upper surface of the outer surface, and the motor shaft 15 is fitted into the lower groove 14 of the truncated cone-shaped fixing cover 6 at the bottom coupled with the pressing plate 5, and the fixing cover ( 6) is fitted in the inner space of the centering cylinder (3).

미설명 부호 9 : 디스크, 10 : 베어링, 11 : 고정덮개(6)의 축, 12, 12' : 누름판 고정용 E링과 와셔, 13 : 중심잡기 원통체를 고정한 나사이다.Not shown 9: disk, 10: bearing, 11: shaft of the fixing cover (6), 12, 12 ': E-ring and washer for fixing the pressing plate, 13: screw fixing the centering cylinder.

본 고안의 작용효과는, 제 3 도는 제 2 도의 디스크원판(1)에 고정된 중심잡기 원통체(3)에 고정덮개(6)를 끼운 상태도로서 중심잡기 원통체(3)가 다수 개의 조각편(3')들이 벌어지면 외면 상측의 돌출부(4)의 경사면에는 디스크(9) 통공주면이 밀착되어 꼭끼게 되므로 디스크(9)는 중심이 잡혀있는 고정덮개(6)의 원주면에 의하여 편심되지 않고 고정되는 것이다.The working effect of the present invention is a state diagram in which the fixing cover 6 is inserted into the centering cylindrical body 3 fixed to the disk disc 1 of FIG. 2, and the centering cylindrical body 3 has a plurality of pieces ( 3 ') are opened, the circumferential surface of the disk 9 is in close contact with the inclined surface of the protrusion 4 of the upper surface of the outer surface so that the disk 9 is not eccentric by the circumferential surface of the fixed cover 6 centered It is fixed.

이 상태에서 모터축(15)이 회전하면 디스크 원판(1)과 디스크(9) 및 고정덮개(6)도 같이 회전하게 된다.When the motor shaft 15 rotates in this state, the disc original plate 1, the disc 9, and the fixing cover 6 rotate together.

이와 같이 본 고안은 구성이 간단하여 제조 및 조립하기가 용이하고 중심잡기 원통체의 고정덮개를 끼우기만 하면 디스크가 원판위에 편심되지 않고 고정되므로 취급도 용이하게 된 것이다.As such, the present invention is easy to manufacture and assemble because the configuration is simple, and simply insert the fixing cover of the centering cylindrical body, so that the disk is fixed without being eccentric on the disc, so that the handling is also easy.
