본 고안은 비디오 테이프 카세트의 테이프릴 안착부 구조에 관한 것으로, 특히 하부케이스와 테이프릴이 요철방식으로 유착되도록 원형리브와 원형요홈을 형성시켜서 테이프릴의 평활도가 양호하게 유지됨과 동시에 마찰력을 극소화시킨 테이프릴 안착부 구조에 관한 것이다.The present invention relates to a tape reel mounting portion structure of a video tape cassette, and in particular, by forming a circular rib and a circular groove so that the lower case and the tape reel are unevenly bonded, the smoothness of the tape reel is maintained and the frictional force is minimized. A tape reel seat structure.
제1도와 같이, 비디오 테이프 카세트(10)는 상·하부케이스(12)(14)로 분리시킨 상태에서 테이프릴(16)(18)과 각종 부품을 가체결시킨 후 스크류로 조립체결하는 것이다(테이프릴(16)(18)은 그 형상과 구성이 동일하므로 이하에서는 하나의 테이프릴(16)을 예시하거나 혼용해서 설명한다).As shown in FIG. 1, the video tape cassette 10 is pre-fastened to the tape reels 16 and 18 in a state of being separated by the upper and lower cases 12 and 14, and then assembled by screws ( Since the tape reels 16 and 18 have the same shape and configuration, one tape reel 16 will be exemplified below or mixed.
특히, 테이프릴(16)은 비디오 테이프(20)가 감겨지도록 고속회전되는 부품으로 그 이면과 정단면 구성은 제2도와 같다.In particular, the tape reel 16 is a component that is rotated at a high speed so that the video tape 20 is wound.
즉, 종래의 테이프릴(16)은 릴록킹기어(21, REEL LOCKING GEAR)가 외주연에 형성되고, 도시되지 아니한 VTR의 구동축에 의해 테이프릴(16)을 구동시키도록 구동기어(24)가 내주에 형성된 중심허브(22)는 그 둘레로 원형리브(26)(28)가 형성된 구조를 이룬다.That is, in the conventional tape reel 16, the reel locking gear 21 (REEL LOCKING GEAR) is formed on the outer circumference, and the drive gear 24 drives the tape reel 16 by the drive shaft of the VTR (not shown). The central hub 22 formed on the inner circumference has a structure in which circular ribs 26 and 28 are formed around the center hub 22.
이와 더불어, 하부케이스(14)의 테이프릴 안착부(20)는 평면인 상태이며, 따라서 테이프릴(16)은 상기 테이프릴 안착부(20)에 면접촉된 채 고속회전하여 비디오 테이프(20)를 감게 된다.In addition, the tape reel mounting portion 20 of the lower case 14 is in a flat state, and thus, the tape reel 16 is rotated at high speed while being in surface contact with the tape reel mounting portion 20 to thereby rotate the video tape 20. Will be wound.
그러나, 상기와 같은 종래의 테이프릴 안착부 구조에서는 테이프릴의 릴하부(16A)가 하부케이스에 접촉되는 면의 평활도가 불량일때에 마찰에 의한 작동불량 현상이 발생하며, 이 경우 구동 모우터에 로드(LOAD)가 많이 걸리게 되는 점은 물론, 마찰에 의한 분진발생으로 테이프면과 VTR의 헤드를 오염시키서 비디오 테이프 카세트 뿐만 아니라, VTR까지 손상시키는 문제가 있었다.However, in the conventional tape reel mounting portion structure as described above, when the smoothness of the surface where the reel lower portion 16A of the tape reel is in contact with the lower case is poor, a malfunction of the friction occurs, and in this case, the driving motor Not only that the load takes a lot, but also the dust generated by the friction contaminates the tape surface and the head of the VTR, thereby damaging not only the video tape cassette but also the VTR.
특히, 테이프릴의 평활도는 테이프릴이 얇은 원판 두께가 중심허브(22)를 중심으로 설치되는 것이서 두께에 비해 면적이 넓은 구조 상태이므로 성형사출시 릴의 평활도 유지가 어려워서 상기한 종래의 문제를 해소시키는데 한계가 되어 왔다.In particular, the smoothness of the tape reel is a thin disk reel is installed around the center hub 22 and the structure is large in area compared to the thickness, so the smoothness of the reel is difficult to maintain during molding injection, thereby solving the above-mentioned problems. It has been a limit to solve.
다시말하면, 제2b도에서와 같이, 테이프릴(16)은 릴하부(16A)와 중심허브(22)가 일체로 형성되고, 중심허브(22)위에 릴상부(16B)가 접합되는 것이어서, 릴상부(16B)와 릴하부(16A)는 두께가 얇은 상태로 성형되므로 평활도 유지가 어려웠던 것이다.In other words, as shown in FIG. 2B, the tape reel 16 is a reel lower portion 16A and the center hub 22 integrally formed, and the reel upper portion 16B is joined to the center hub 22, so that the reel is reeled. Since the upper portion 16B and the reel lower portion 16A were molded in a thin state, smoothness was difficult to maintain.
본 고안은 상기한 제반문제를 고려하여 안출된 것이다.The present invention has been devised in consideration of the above-mentioned problems.
이를 위하여 테이프릴의 하부면 중앙부에 테이프릴의 평활도를 유지시켜줄 원형리브를 형성시키고, 상기 원형리브가 닿는 하부케이스의 테이프 안착부에 원형요홈을 형성시킴에 따라, 테이프릴 구동시에 상기 요홈에 원형리브가 안착된 채 회전되므로, 테이프릴의 요동없이 일정하게 회전할 수 있으며, 이때문에 접촉면적이 최소화되고 릴록킹상태도 정확하게 유지되도록 한 것이다.To this end, a circular rib is formed in the center of the lower surface of the tape reel to maintain the smoothness of the tape reel, and a circular groove is formed in the tape seat portion of the lower case to which the circular rib is in contact. Since it is rotated while seated, it can be rotated without shaking the tape reel, thereby minimizing the contact area and keeping the relocking state accurately.
이하, 첨부도면을 참고하여 본 고안을 상술하면 다음과 같다.Hereinafter, the present invention with reference to the accompanying drawings as follows.
본 고안은 테이프릴(16)(18)의 외주면과 원형리브(26)사이에 동심원의 원형리브(32)를 형성시키고, 이에 대용되는 하부케이스(14)의 테이프릴 안착부(20)에 원형요홈(34)을 형성시켜 이루어지는 테이프릴 안착부 구조이다.The present invention forms a concentric circular rib 32 between the outer circumferential surface of the tape reels 16 and 18 and the circular ribs 26, and a circular shape in the tape reel seat 20 of the lower case 14 that is substituted therefor. It is a tape reel mounting portion structure formed by forming the groove 34.
제3도 (a)는 본 고안이 적용된 테이프릴(16)의 이면도로써, 원형리브(32)는 릴하부(16A)(18A)의 중심허브(22) 둘레에 형성된 원형리브(26)와 릴록킹기어(21)사이의 동심원상에 형성시켜면 되며, 이에따라 제3b도에서처럼 원형요홈(34)도 하부케이스(14)상에 대응되는 위치에 형성되어서 테이프릴 안착부(20)에 테이프릴(16)이 놓여지면 테이프릴(16)(18)의 원형리브(32)는 원형요홈(34)에 미끄럼 이동이 가능하도록 안착된다.FIG. 3 (a) is a rear view of the tape reel 16 to which the present invention is applied, and the circular rib 32 is formed with a circular rib 26 formed around the center hub 22 of the lower reels 16A and 18A. The concave circle may be formed between the reel locking gears 21. Accordingly, as shown in FIG. 3B, the circular groove 34 is also formed at a position corresponding to the lower case 14 so that the tape reel is mounted on the tape reel seat 20. When the 16 is placed, the circular ribs 32 of the tape reels 16 and 18 are seated in the circular recess 34 so as to be slidable.
여기서, 원형리브(32)와 원형요홈(34)은 상기 테이프릴(16)의 이전에는 영향을 주지 않도록 마찰력을 극소화시키는 정도의 크기로 형성되며, 이를 위한 형상이나 구조가 반원형 단면으로만 형성되지 아니함은 자명한 일인것이다.Here, the circular rib 32 and the circular groove 34 is formed to a size that minimizes the friction force so as not to affect the transfer of the tape reel 16, the shape or structure for this is not formed only in a semi-circular cross section Nothing is self-evident.
따라서, 종래와 같이 테이프릴 하면과 하부케이스의 테이프릴 안착부(20)가 면접촉되던 상태에서 원형리브(32) 및 원형요홈(34)만 접촉되므로 마찰면적으로 최소화시킬 수 있게 되며, 특히, 원형리브(32)는 보강대 역할을 갖게 되므로써 테이프릴의 평활도가 양호한 상태로 유지시켜 주는 특별한 기능도 겸하게 된다.Therefore, in the state where the tape reel mounting portion 20 of the lower surface of the tape reel and the lower case, as in the prior art, only the circular rib 32 and the circular groove 34 are in contact, so that the friction area can be minimized. Since the circular rib 32 has a role of reinforcing bar, the circular rib 32 also serves as a special function of maintaining the smoothness of the tape reel.
상기한 원리대로라면 원형리브(32)를 하부케이스(14)에 형성시키고, 하부케이스(14)의 원형요홈(34)을 원형리브로 형성시킨다 해도 동일한 구성원리를 가지며, 마찰력도 동일하며, 제4도와 같이 보다 실용적으로 성형시키기 위해서 하부케이스(14)에 원형리브(32')을 형성시킨다면 릴하부(16A)와 테이프릴 안착부(20)에 닿는 면적을 최소화시킬 수 있으며, 가이드 역할까지 겸할 경우 제5도처럼 원형리브(32')가 테이프릴(16)의 원형리브(32)에 내접하든지, 제6도처럼 외접하게 형성시킬 수도 있다.According to the principle described above, even if the circular rib 32 is formed in the lower case 14, and the circular groove 34 of the lower case 14 is formed into the circular rib, it has the same membership, the frictional force is the same, and the fourth If the circular ribs 32 'are formed in the lower case 14 in order to form them more practically, the area of contact with the lower reel 16A and the tape reel mounting portion 20 can be minimized. As shown in FIG. 5, the circular ribs 32 ′ may be inscribed with the circular ribs 32 of the tape reel 16, or may be formed externally as shown in FIG. 6.
