본 고안은 스틸 비디오 플로피 디스크(Still Video Floppy Disk)의 록킹 장치에 관한 것으로서, 특히 셔터 록커의 구조를 단순화 하면서 그 기능을 강화시킬 수 있도록 개량한 록킹장치에 관한 것이다.The present invention relates to a locking device of a still video floppy disk (Still Video Floppy Disk), and more particularly to a locking device improved to enhance the function while simplifying the structure of the shutter locker.
일반적으로 스틸 비디오 플로피 디스크는 내부로 디스크를 두고 그 상하에 이 물질로 부터 디스크를 보호하며 완전히 밀봉되어 열리지 않도록 초음파로 용접되는 쉘업 및 쉘다운을 외부 갑체로 하여 형성되어지며, 상기 쉘업 및 쉘다운의 전측 중앙부에는 디스크의 양표면을 외부로 노출시켜 데이터를 읽고 쓰는 작업을 가능케하는 헤드윈도우(Head Window)가 형성되어지고 이의 외부에는 디스크를 외부로부터 보호하기 위한 셔터가 탄설되어지는 데, 상기의 셔터는 일측으로 관통공이 천공되고 좌우 슬라이드가 자유자재하게 설치되어 좌우 이동되면서 상기 헤드 윈도우를 개폐시켜 줄수 있도록 형성되어, 전체적인 구성을 이루게 된다.Generally, still video floppy disks are formed with an outer shell of shell-up and shell-down welded by ultrasonic so that the disk is kept inside and the disk is protected from foreign matter above and below, and is not completely sealed. A head window is formed at the front center of the disk to expose both surfaces of the disk to the outside to read and write data, and a shutter is provided outside the shutter to protect the disk from the outside. The shutter is formed so as to open and close the head window while the through-hole is drilled to one side and the left and right slides are installed freely to move left and right, thereby forming the overall configuration.
상기와 같은 스틸 비디오 플로피 디스크에 있어서, 셔터는 플로피 디스크를 사용치 않을시 항상 닫힘 상태가 유지되도록 스프링에 의해 탄설되어 플로피 디스크 드라이버 내로 장착되면 드라이버 내에 형성된 개폐구에 의해 일측으로 이동되면서 헤드 윈도우을 열어주게 되며, 상기와는 반대로 플로피 디스크 드라이버로 부터 인출되면 스프링에 의해 이동되면서 헤드 윈도우를 폐쇄하게 되는데, 이때 셔터가 닫혀진 상태에서는 내부에 형성된 셔터 록킹장치에 의해 록킹상태가 유지된다.In the still video floppy disk as described above, the shutter is installed by a spring so that the shutter is always kept closed when the floppy disk is not in use, and when mounted into the floppy disk driver, the head window is moved to one side by an opening and closing hole formed in the driver to open the head window. On the contrary, when the card is withdrawn from the floppy disk driver, the head window is closed while being moved by the spring. In this case, the locked state is maintained by the shutter locking device formed therein.
이와 같이 셔터의 닫힘 상태를 유지시켜 주는 셔터의 록킹장치를 형성함에 있어서 종래에는 제 4 도에 도시한 바와 같이 중간부가 만곡되어져 탄성이 부여되는 탄성부(51)를 두고 일측으로 상면으로 걸림홈(52)이 형성된 걸림편(53)과 그 하측부에서 분기되는 멈춤돌기(54)가 형성되며 타측으로는 고정공(55)과 끼움공(56)을 갖는 고정편(57)이 일체로 형성된 셔터 록커(50)를 쉘다운(60)의 내면 일측부에 돌설되는 고정돌기(61)와 끼움돌기(62)에 상기 고정공(55)과 끼움공(56)을 대응되게 끼워 고정하는 수단을 형성하여 셔터(70)의 닫힘시 셔터(70)의 내측 방향으로 돌설되는 걸림구(71)가 상기 셔터 록커(50)의 걸림홈(52)에 삽입되면서 셔터(70)를 록킹시켜주도록 하는 것이 통상적이었다.As described above, in forming the locking device for the shutter that maintains the shutter closed state, as illustrated in FIG. 4, the intermediate part is curved to have an elastic part 51 to which elasticity is applied. 52 is formed with a locking piece 53 formed therein and a stop projection (54) branched from the lower portion is formed, the other side is a shutter formed integrally with the fixing piece 57 having a fixing hole 55 and the fitting hole 56 The locker 50 forms a means for correspondingly fixing the fixing hole 55 and the fitting hole 56 to the fixing protrusion 61 and the fitting protrusion 62 protruding from one side of the inner surface of the shell down 60. When the shutter 70 is closed, it is usual to lock the shutter 70 while being inserted into the locking groove 52 of the shutter locker 50 when the locking hole 71 which protrudes in the inward direction of the shutter 70. It was.
그러나 상기와 같은 종래의 록킹장치에 있어서는 셔터록커(50)의 고정수단이 매우 복잡하여 셔터록커(50)의 사출 성형시 금형의 구조가 복잡해지며 또한 기능상에 있어서도 열화 현상을 초래하는 문제점을 내포하고 있었다.However, in the conventional locking device as described above, the fixing means of the shutter locker 50 is very complicated, so that the mold structure is complicated during injection molding of the shutter locker 50, and also includes a problem of deterioration in function. there was.
따라서 본 고안은 상기와 종래 제반 문제점을 해결하여 셔터 록커의 구조를 단순화 시키면서 그 기능을 강화시킬수 있는 스틸 비디오 플로피 디스크의 셔터 록킹 장치를 제공하려는 것이다.Accordingly, the present invention is to provide a shutter locking device for a still video floppy disk that can enhance the function while simplifying the structure of the shutter locker by solving the above and conventional problems.
이하, 본 고안은 첨부한 도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
제 1 도는 본 고안이 적용되는 스틸 비디오 플로피 디스크의 일부 절개 사시도로서, 쉘업(1)과 쉘다운(2) 사이에 디스크(3)가 내장되고 전측부에 미도시된 헤드 윈도우를 개폐시켜주는 셔터(4)를 구비하여 구성되어지는데, 상기 셔터(4)의 닫힘 상태를 록킹 시켜 주는 록킹장치는 셔터(4)가 닫혀지는 위치에 형성되어지며 이에 적용되는 셔터 록커(10)는 제 2 도에 도시한 바와 같이 후반의 중간부에 탄성이 부여되도록 만곡되어진 탄성부(11)를 두고 일측 방향으로는 중간부 상면에 걸림홈(12)이 형성된 걸림편(13)과 그 하측에서 분기되는 멈춤돌기(14)가 형성되며, 타측 방향으로는 직선부(15)로 형성된 그의 단부가 지지구(16)가 일체로 형성된 고정부(17)가 형성되어져 쉘다운(2)의 전측벽(5) 내면으로 일정길이로 형성되는 보강리브(6)에 마련된 고정홈(7)에 직선부(15)를 억지끼움수단으로 결합되어진다.1 is a partially cutaway perspective view of a still video floppy disk to which the present invention is applied, and a shutter for opening and closing a head window not included in the front side of the disk 3 between the shell-up 1 and the shell-down 2; And a locking device for locking the closed state of the shutter 4 is formed at a position where the shutter 4 is closed, and the shutter locker 10 applied thereto is shown in FIG. As shown in the drawing, the elastic part 11 is bent so that elasticity is imparted to the middle part of the second half, and in one direction, the locking piece 13 having the locking groove 12 formed on the upper surface of the middle part and the stop protrusion branching from the lower part thereof. 14 is formed, and in the other direction, an end portion thereof formed of a straight portion 15 is formed with a fixing portion 17 having integrally formed supports 16 formed therein so that the inner surface of the front wall 5 of the shell down 2 is formed. A straight portion in the fixing groove (7) provided in the reinforcing rib (6) formed to a certain length 15) are combined with interference fitting means.
상기에서 걸림편(13)의 상부에 형성된 걸림홈(12)에는 셔터(4)의 닫힘시 셔터(4)의 상면 일측에서 내측 방향으로 돌설되는 걸림구(8)가 삽입되어져 셔터(4)의 록킹 상태를 시켜 주는 것이며, 멈춤돌기(14)는 셔터(4)의 열림시 걸림편(13)이 자체탄성에 의해 상측으로 복귀되어질때 쉘다운(2)에 형성된 디스크 안내턱의 선단부에 마련된 걸림턱(9)과 접촉되면서 걸림편(13)의 복귀 범위를 한정시켜 준다.The locking groove 12 formed above the locking piece 13 is inserted with a locking hole 8 protruding inward from one side of the upper surface of the shutter 4 when the shutter 4 is closed, so that the shutter 4 is closed. The locking projection 14 is a locking protrusion provided at the distal end of the disk guide jaw formed in the shell down 2 when the locking piece 13 is returned to the upper side by self-elasticity when the shutter 4 is opened. While contacting the jaw (9) limits the return range of the locking piece (13).
이와 같이 구성된 본 고안의 작용효과를 설명하면 다음과 같다.Referring to the effect of the present invention configured as described above are as follows.
본 고안에 적용된 셔터록커(10)의 작용은 종래와 같이 스틸 비디오 플로피 디스크의 불사용시 셔터(4)가 닫히면 제 3 도의 실선과 같이 걸림편(13)의 걸림홈(12)에 셔터(4)의 록킹 상태를 유지시켜 주게 되는 것으로서, 그 조립과정은 셔터록커(10)의 후부측부인 직선부(15)를 쉘다운(2)의 보강리브(6)에 형성된 고정홈(7)에 억지 끼움 수단으로 조립시키면 되는 것이다.The action of the shutter locker 10 applied to the present invention is that when the shutter 4 is closed when the still video floppy disk is not in use as in the prior art, the shutter 4 is inserted into the locking groove 12 of the locking piece 13 as shown in FIG. It is to maintain the locked state of the assembly, the assembly process forcibly fitting the straight portion 15, which is the rear side of the shutter locker 10 in the fixing groove 7 formed in the reinforcing ribs 6 of the shell down (2). What is necessary is just to assemble by means.
따라서 본 고안에 의해 구성된 셔터 록커(10)는 고정부인 그 후측부를 단순히 직선부(15)로 형성하여 쉘다운(2)의 기존보강리브(6)에 고정토록 하였는바, 종래에 비하여 구조가 단순화 되고 이에 따른 성형 불량이 작게 발생되어 짐은 물론 수지절감의 효과가 있는 것이다.Therefore, the shutter locker 10 constructed by the present invention is formed by simply forming the rear portion of the rear portion as a straight portion 15 so as to be fixed to the existing reinforcement ribs 6 of the shell down 2, and the structure is as compared with the prior art. Simplified and the resulting molding failure is small, as well as the effect of reducing the resin.
이상에서와 같이 본 고안에 의하면 스틸 비디오 플로피디스크에 있어서 셔터 록커의 구조를 단순화 하면서 그 기능을 강화시킬수 있는 매우 유용한 고안인 것이다.As described above, according to the present invention, it is a very useful design that can enhance the function while simplifying the structure of the shutter locker in the still video floppy disk.
