본 고안은 컴팩트 디스크 드라이브의 디스크 장착장치에 대한 것으로 더 자세히 말하자면 디스크를 안정된 상태로 잡아 주고, 생산성을 향상시키기 위해 구조를 개량한 것이다.The present invention relates to a disk mounting apparatus of a compact disk drive. More specifically, the structure is improved to hold the disk in a stable state and to improve productivity.
일반적으로 컴팩트 디스크 드라이브에는 턴테이블이 있고, 이 턴테이블의 중앙에는 안착된 디스크를 보다 안정된 상태에서 작동할 수 있도록 견고히 잡아주는 장착장치가 았다.In general, a compact disk drive has a turntable, and in the center of the turntable is a mounting device that firmly holds the seated disk to operate in a more stable state.
이러한 종래의 장치는 제5도 도면에서 보는 바와 같이 원추 모양의 중앙부(a)가 있고, 내부에는 지지기구(b)에 끼워진채 외측으로 탄성력을 갖도록 설치된 다수의 스프링(c)에 각각의 볼(d)들이 내장되어 있다.Such a conventional apparatus has a conical central portion (a) as shown in FIG. 5, and has a ball (i) mounted on a plurality of springs (c) installed to have an elastic force on the outside while being fitted to the support mechanism (b). d) are built-in.
이는 중앙부(a)위로 컴팩트 디스크(D)가 끼워지면 초기에 디스크(D)가 볼(d)위에 얹히므로 디스크(D)의 내경이 볼(d)을 누르면서 내려가게 되고, 바닥까지 완전히 내려간 후에는 다시 볼(d)이 외측으로 밀려가기 때문에 디스크(D)의 내경 상반부를 잡고 있게 되는 것이다.This is because when the compact disc D is inserted onto the center part a, the disc D is initially placed on the ball d. Therefore, the inner diameter of the disc D is lowered while pressing the ball d. Is again holding the upper half of the inner diameter of the disk (D) because the ball (d) is pushed outward.
그러나 이러한 종래의 장착장치는 중앙부(a)속에 지지기구(b)를 내장하고, 스프링(c)과 볼(d)을 조립해야 하는바, 이는 부품이 많기 때문에 비경제적일 뿐만 아니라 조립작업이 난해하여 생산성이 나쁜것이며, 특히 스프링(c)의 탄성에 변화가 있을 경우와, 볼(d)의 주위에 이물질이 끼었을 경우, 안정적인 장착이 보장되지 못하고, 또 슬립현상이 발생할 수 있어 여러 가지 결함이 많은 것이었다.However, such a conventional mounting device has to incorporate a support mechanism (b) in the center portion (a) and to assemble the spring (c) and the ball (d), which is not only economical because of the large number of parts, but also difficult to assemble. This is a poor productivity, especially when there is a change in the elasticity of the spring (c), and when foreign matter is caught around the ball (d), stable mounting is not guaranteed and slipping may occur This was a lot.
따라서 본 고안은 상기와 같은 종래의 여러 가지 문제점을 해결하기 위해 안출한 것으로 고안의 주된 목적은 원추모양의 중앙부 구조를 개선하여 그 자체로서 탄성기능 및 걸림턱기능을 함께 가질수 있도록 하므로서 디스크의 안정된 장착과, 슬립의 예방, 생산성 향상 및 저가보급 실현에 있는 것이다.Therefore, the present invention has been devised to solve various problems of the prior art, and the main purpose of the present invention is to improve the structure of the central portion of the cone shape so that it can have both elastic and locking jaw functions as its own, thus ensuring stable mounting of the disk. It is to prevent slippage, improve productivity, and realize low-cost supply.
이와같은 목적을 달성하기 위하여 본 고안에 따른 컴팩트 디스크 드라이브의 디스크 장착장치는, 외주연부의 받침 환테와, 받침 환테 중앙에 구비된 척킹 기구와, 그 중앙에 축착된 회전축으로 이루어진 턴테이블에 있어서, 상기 척킹 기구는 원추부와, 이 원추부의 외주연으로부터 120도 등각도로 절개되어 연장 형성되어 소정의 탄성력을 갖는 절개편과, 이 절개편의 모서리에 돌출 형성되는 걸림턱으로 이루어진 것을 그 특징으로 한다.In order to achieve the above object, the disk mounting apparatus of the compact disc drive according to the present invention includes a support frame of the outer periphery of the outer periphery, a chucking mechanism provided in the center of the support ring, and a turntable which is condensed in the center thereof, wherein The chucking mechanism is characterized by consisting of a conical portion, a cut piece which is cut out at an angle of 120 degrees from the outer periphery of the cone portion and extends to have a predetermined elastic force, and a locking jaw protruding from the corner of the cut piece.
이하 첨부도면에 따라 본 고안의 상세한 구성 및 작용효과를 설명하면 다음과 같다.Hereinafter, the detailed configuration and effect of the present invention according to the accompanying drawings.
제1도 및 제2도는 본 고안의 턴테이블(1)을 보인 정단면도와 원추부의 평면도로서 회전축(2)이 축착된 받침 환테(11)가 있고, 이 받침 환테(11)의 위에는 본 고안의 척킹 기구(3)가 마련되어 있다.1 and 2 are a front sectional view showing the turntable 1 of the present invention and a top view of the conical part, and a support ring frame 11 on which the rotation shaft 2 is condensed, and on the support ring frame 11, the chucking of the present design is carried out. The mechanism 3 is provided.
척킹 기구(3)는 합성수지재의 사출물로 이루어진 원추부(31)가 있고, 이 원추부(31)의 외주연에서 절개된 채 더 바깥쪽으로 벌어진 절개편(32)이 형성되어 있다.The chucking mechanism 3 has a conical part 31 made of an injection molded product of synthetic resin material, and is formed with an incision piece 32 which is further opened while being cut off at the outer circumference of the conical part 31.
절개편(32)은 120도 등간격으로 즉, 3방향으로 하단이 경사진 채 벌어진 것으로 그 절개편의 모서리에는 걸림턱(35)이 마련되어 있다.The cutting pieces 32 are formed at equal intervals of 120 degrees, that is, the lower ends are inclined in three directions, and the locking jaw 35 is provided at the edge of the cutting pieces.
또한 본 고안은 제4도 도면에서 보는 바와 같이 달리 실시할 수 있다.In addition, the present invention can be implemented differently as shown in FIG.
즉, 상기한 절개편(32)의 안쪽에 스프링(33)을 포함하는 지지부재(34)를 탄력적으로 설치히여 탄력이 배가되도록 형성되어 있다.That is, it is formed so that the elasticity is doubled by elastically installing the support member 34 including the spring 33 inside the cut piece 32.
다음은 상기와 같이 구성된 본 고안의 작동상태에 대해서 설명한다.The following describes the operating state of the present invention configured as described above.
상기와 같이 턴테이블(1)이 완성된 상태에서 디스크(D)를 장착할 경우 먼저 디스크(D)의 내경이 3방향의 절개편(32)의 위로 앉히게 되며, 이때, 절개편(32)들은 원추부(31)보다 더 바깥쪽으로 돌출되어 있었기 때문에 디스크 내경에 의해 안쪽으로 눌리며, 디스크가 완전히 턴테이블(1)위에 얹히고 나면 바깥쪽으로 벌어지려는 힘 때문에 척킹이 되는 것이다.When the disk D is mounted in the state where the turntable 1 is completed as described above, the inner diameter of the disk D is first seated on the cut piece 32 in three directions, and the cut pieces 32 are Since it protrudes outwardly than the cone part 31, it is pressed inward by the inner diameter of the disk, and the disk is chucked due to the force to be outwardly after the disk is completely placed on the turntable 1.
특히 제4도 도면에서와 같이 안쪽에 스프링(33)을 포함하는 지지부재(34)가 있을 경우 더욱 견고하고 안정되게 척킹을 할 수 있으며, 또 상기한 절개편(32)의 모서리에는 도면에서 보듯이 걸림턱(35)이 있어 어느정도 진동이 있어도 쉽게 빠지지 않게 된다.In particular, when the support member 34 including the spring 33 therein as shown in Figure 4 can be more firmly and stably chucking, and in the corner of the cut piece 32 as shown in the drawing There is a locking jaw (35), so even if there is some vibration does not fall easily.
이상에서 자세히 설명한 바와 같이 본 고안은 턴테이블상에 디스크를 장착함에 있어서 스프링에 탄설된 볼타입과 달리 원추부(31)에서 자체적으로 절개하여 형성한 절개편(32)과, 그 안쪽에 마련한 스프링(33), 지지부재(34)에 의해 탄성을 가진 채 압착되므로 장착효과가 좋을 뿐만 아니라 디스크의 슬립현상이 방지되며, 특히 불타입에 비해 구조가 간단하기 때문에 부품이 크게 생략되어 생산원가 절가에 유리하고 생산성이 향상되는 매우 유용한 고안인 것이다.As described in detail above, the present invention, unlike the ball type installed in the spring in mounting the disk on the turntable, the cut piece 32 formed by cutting itself in the conical part 31 and the spring provided therein ( 33) Since it is crimped with elasticity by the support member 34, not only the mounting effect is good but also the slip phenomenon of the disk is prevented. It is a very useful design that improves productivity.
