본 고안은 비디오 테이프 가세트에 내장되는 릴에 있어서, 특히 릴 다운에 일체화 되는 보스 상면의 센터보스(CINTER BOSS)결합부에 센터보스의 결합돌기를 형성시켜 별도롤 제작된 센터보스의 조립시 견고하게 가조립 상태가 유지되게 하여 조립성을 향상시킴을 물론 센터보스의 받침부 일측에 게이트부를 요입시킴으로써 센터보스의 사출 성형시 게이트부가 깨끗이 처리될수 있도록 개량한 비디오 테이프카세트의 릴 센터 보스 구조에 관한 것이다.The present invention is robust in assembling the center boss fabricated separately by forming the center boss coupling part in the center boss coupling part of the boss upper surface integrated with the reel down in the reel embedded in the video tape set. The reel center boss structure of the video tape cassette is improved so that the prefabricated state can be maintained to improve the assemblability, and the gate part is inserted into one side of the support part of the center boss so that the gate part can be cleanly processed during the injection molding of the center boss. .

일반적으로 비디오테이프카세트에는 제7도에서 보는바와 같이 서플라이 릴(30)과 테이프 업 릴(31)이 내장되어 이에 감겨진 테이트(T)를 양측 릴이 상호보완적으로 보호되면서 테이프를 주행시키게 되는데 카세트에 내장된 릴에 유동을 방지하기 위하여 적당한 탄성을 가진 릴 지지용 스프링(32)이 상부 케이스에 설치되어 릴 다운의 보스 상부에 돌설되는 센터보스를 가압하여 주도록 되어 있는 것으로 릴의 유동에 따라서 릴 지지용 스프링과 접촉되는 센터보스는 내마모성을 지닌 재질로 구성되어야 하는 것이다.In general, as shown in FIG. 7, the video tape cassette has a supply reel 30 and a tape up reel 31 built therein, and both sides of the reel complementarily protect the tape wound thereon. A reel support spring 32 having an appropriate elasticity is installed in the upper case to pressurize the center boss protruding from the upper part of the boss of the reel down in order to prevent flow to the reel embedded in the cassette. The center boss, which is in contact with the reel support spring, should be made of a material with wear resistance.

이와같은 센서보스를 형성함에 있어서, 종래에는 제8도에서 보는 바와같이 릴 다운(20)의 보스(21)상부면에 돌설되는 센터보스(22)가 릴다운(20)의 성형시 일체로 사출 성형되게 한 것이었다In forming such a sensor boss, conventionally, as shown in FIG. 8, the center boss 22 protruding from the upper surface of the boss 21 of the reel down 20 is integrally ejected when the reel down 20 is molded. Was molded

그러나 상기와 같은 구조에 있어서는 일정 기준치 이상의 내마모성을 지녀야 한다는 센터보스의 재질상 특성때문에 릴 다운을 센터 보스와 더불어 고가인 재질로 일체 성형하여야 함으로써, 불 필요한 재료의 낭비로 원가상승의 요인이 되는 문제점이 있었다.However, in the structure as described above, due to the material characteristics of the center boss that has a wear resistance of more than a certain standard value, the reel down must be integrally formed with an expensive material together with the center boss, thereby causing a cost increase due to waste of unnecessary materials. There was this.

따라서 이를 극복하기 위한 수단으로 제9도와 같이 고가의 재질을 요하는 센터보스(40)를 릴 다운(51)과는 별도 제작한 것이 있으나, 이와 같은 센터보스(40)를 릴 다운(51)의 보스(52)상면에 조립함에 있어서는 보스(52)의 상면에 센터보스(40)를 단순히 올려 놓은 상태에서 릴 업(53)을 조립해야 하는바, 이 과정에서 센터보스(40)가 이탈될 염려가 있음은 물론, 이로 인하여 조립이용이하지 못한 다는 문제점이 있었다.Therefore, as a means for overcoming this, the center boss 40, which requires an expensive material as shown in FIG. 9, is manufactured separately from the reel down 51, but such a center boss 40 may be In assembling on the upper surface of the boss 52, the reel-up 53 should be assembled while the center boss 40 is simply placed on the upper surface of the boss 52. In this process, the center boss 40 may be detached. Of course, there was a problem that it is not easy to assemble due to this.

또한 릴 다운(51)의 보스(52)상부 용입부(54)에 센터보스(40)를 올려 놓음에 있어서는 센터보스(40)의 받침부(41)일측에 형성되는 게이트부(42)가 제10도와 같이 깨끗하게 처리되지 못하면 릴 업(53)을 조립하는 경우에는 불량이 발생되는 문제점이 있었다.In addition, when placing the center boss 40 on the upper penetration part 54 of the boss 52 of the reel down 51, the gate part 42 formed on one side of the support part 41 of the center boss 40 is formed. If it is not clean, such as 10 degrees when the reel assembly (53) there was a problem that a defect occurs.

따라서 본 고안은 이러한 종래 릴 다운의 구조적 문제점을 해결하기 위하여 안출한 것으로, 이를 첨부된 도면에 의하여 본 고안의 구성 및 작용효과를 상세히 설명하면 다음과 같다.Therefore, the present invention has been devised to solve the structural problems of the conventional reel down, and the configuration and operation effects of the present invention by the accompanying drawings in detail as follows.

도시한 바와 같이 릴 다운(1)에 일체로 형성되는 보스(2)의 상부면에 돌기(3)를 적정 간격으로 돌설하여 릴 업(4)의 홀(5)과 융착 결합되는 공지의 비디오 테이프 카세트 릴(6)에 있어서, 적당한 내마모성을 갖는재질로 센터보스(7)를 릴 다운(1)과는 별도로 성형하되 비교적 저렴한 재질로 성형되는 릴 다운(1)과 일체로 성형된 보스(2)의 상부면 중앙에 센터보스(7)의 받침부(8)가 안착되는 요입부(12)를 형성하되, 그 중앙에 상광하협의 곡선으로 형성되는 겨랍돌기(13)를 형성하고 이에 조립되는 센터보스(7)는 원판상의 받침부(8)중앙 상부로 공지의 릴 지지용 스프링과 접촉되는 돌기(10)를 형성하여, 이 돌기(10)의 내부로 결합돌기(13)와 대응하는 요홈(11)을 형성하며, 받침부(8)의외주연 일측에는 적당한 크기의 반원형으로 요입되는 게이트부(9)를 형성하여서 된 것이다.As shown in the figure, a projection 3 is projected on the upper surface of the boss 2 integrally formed on the reel down 1 at appropriate intervals to be fusion-bonded with the hole 5 of the reel up 4. In the cassette reel (6), the boss (2) integrally formed with the reel down (1), which is molded separately from the reel down (1) by a material having suitable abrasion resistance, but is formed of a relatively inexpensive material. The center of the upper surface of the center boss (7) is formed in the recessed portion 12 is seated on the seat, the center is assembled to form a claw projection 13 formed in the curve of the upper and lower strait in the center The boss 7 forms a projection 10 in contact with a well-known reel support spring at the center of the base portion 8 of the disc, and has a recess corresponding to the engaging projection 13 in the protrusion 10. 11) and a gate portion 9 concave in a semicircle of a suitable size is formed on one side of the outer circumference of the support portion 8. will be.

이와같이 구성되는 본 고안은 센터보스(11)가 릴 다운(1)의 보스(2)에 끼움수단으로 고정 설치되는 것으로 작용효과를 설명하면 다음과 같다.When the present invention is configured as described above, the center boss 11 is fixed to the boss 2 of the reel down 1 by fitting means.

우선, 본 고안에 의한 센터보스(7)의 조립 과정은 센터보스(7)의 요홈(11)을 릴 다운(1)의 결합돌기(13)을 삽입하면 받침부(8)가 요입부(12)에 안착되면서 요홈(11)과 결합돌기(13)가 결합되어 센터보스(7)가 1차 견고하게 고정되고, 이 상태에서 보스(2)의 상면에 릴 업(4)을 결합하면 릴 업(4)이 센터보스(7)의 받침부(8)를 눌러주면서 2차 고정시켜 주게 되는 것이다.First, in the process of assembling the center boss 7 according to the present invention, when the coupling protrusion 13 of the reel down 1 is inserted into the recess 11 of the center boss 7, the supporting part 8 is recessed part 12. The recess 11 and the engaging protrusion 13 are coupled to each other so that the center boss 7 is firmly fixed first, and the reel up 4 is coupled to the upper surface of the boss 2 in this state. (4) while pressing the support portion 8 of the center boss (7) is to be fixed second.

이와같이 본 고안에 의한 센터보스(7)의 조립 과정에서는 센터 보스(7)의 요홈(11)과 허브(2)의 결합돌기(13)가 억지끼움 수단으로 1차 고정되어지는 바, 릴업(4)의 결합과정에서 센터보스(7)가 허브(2)의 요입부(12)로부터 이탈될 염려가 없어 조립 공정이 매우 용이하다.In this way, in the assembling process of the center boss 7 according to the present invention, the groove 11 of the center boss 7 and the engaging protrusion 13 of the hub 2 are first fixed by the interference fitting means, and the reel up 4 ), There is no fear that the center boss 7 may be detached from the recess 12 of the hub 2 in the process of coupling.

또한, 센터보스(7)의 받침부(8)일측에 마련되는 게이트부(9)를 형성함에 있어서는 적정크기의 반원형으로 요입시켜 형성하였는 바, 게이트부(9)가 깨끗하게 처리되지 않더라도 제3도와 같이 반원형으로 게이트부(9)가 형성되므로 센터보스(7)의 1차고정시 허브(7)의 요입부(12)에 정확하게 안착됨으로써 이로인한 불량발생의 염려가 없는 것이다.In addition, in forming the gate portion 9 provided on one side of the support portion 8 of the center boss 7, it is formed in a semi-circle of the appropriate size, so that even if the gate portion 9 is not processed cleanly, Since the gate portion 9 is formed in a semicircular shape as described above, there is no fear of failure due to accurate seating on the recess 12 of the hub 7 when the center boss 7 is first fixed.

이상에서와 같이 본 고안에 의하면 릴 다운과 별도로 제작되는 센터보스를 릴 다운의 허브 상면에 결합시킴에 있어서, 릴 다운 허브의 상면에 결합돌기를 형성하고 센터보스에는 상기 결합돌기와 대응하는 요홈을 억지 끼움수단으로 가조립 상태가 되게 한 후, 릴 업을 결합함으로써, 조립과정에서 센터보스의 이탈을 방지하여 작업성을 향상시키고, 게이트부를 요입시킴으로써, 게이트부를 깨끗히 처리할수 있는 바, 이에 따른 여러가지 장점을 기대할 수 있는 매우 유용한 고안인 것이다.As described above, according to the present invention, when the center boss manufactured separately from the reel down is coupled to the hub upper surface of the reel down hub, a coupling protrusion is formed on the upper surface of the reel down hub, and the center boss suppresses the groove corresponding to the coupling protrusion. By putting the reel-up by the fitting means, by combining the reel, it prevents the separation of the center boss during the assembly process to improve workability, and by inserting the gate portion, the gate portion can be cleanly processed. It's a very useful design you can expect.
