본 고안은 VTR(Video Tape Recorder)이나 VCR(video Casette Recordr) 등에 사용되는 헤드드럼(head Drum)의 테이프 풀림 방지장치에 관한것으로 테이프 풀림방지편을 상부 드럼 상연 일측에 직접 설치함으로써 기존의 복잡한 테이프 풀림장치를 개선한 것이다.The present invention relates to a tape drum preventing device of a head drum used in a VTR (video tape recorder) or a VCR (video casette recorder). The loosening device is improved.
종래에는 헤드드럼 테이프 풀림방지장치를 구성함에 있어서 첨부도면 제1도에 도시된 바와같이, 후단에서 선단측으로 점차 좁아지는 사다리꼴 형상의 주연을 하향절곡하여 그 주앙에 원형공(7a)을 선단측으로 약간 치우치게 천설하며, 후단 좌,우 양측에는 하단에 결합부(7b')가 형성된 다리(7b)를 형성하되 좌측다리(7b)가 우측다리(7b)보다 약간 짧게 하여 일정 각도 기울어 지도록 테이프 풀림 방지구(7)를 구성하고, 상기한 테이프 풀림 방지구(7)를 첨부도면 제2도에 도시된 바와같이 드럼베이스(8)에 착설되어 외주연에는 리더라인(1b')이 형성된 하부드럼(1b)과 그 상측에 진동모터(9)의 구동축(10)에 축착되어 회동되도록 설치되어 레드(6)를 장착한 상부드럼(1a)으로 구성된 헤드드럼(1)에 상기 테이프풀림방지구(7)의 원형공(7a)이 상부드럼(1a)상단의 축수부(1a")률 감삽토록 하여 테이프 풀림방지구(7)의 다리(7b) 하단에 형성된 결합부(7b')를 드럼베이스(8)에 천설된 결합공(8a)에 결합함으로써 테이프 풀림 방지구(7)가 헤드드럼(1)을 구성하는 상부드럼(1a)을 구성하는 상부 드럼(1a)의 상단 주연(1a') 전체를 덮어씌운 형상을 하는 것이다.Conventionally, in the construction of the head drum tape anti-loosening device, as shown in FIG. 1 of the accompanying drawings, the bent end of the trapezoidal shape gradually narrowing from the rear end to the tip side is bent downward, and the circular hole 7a is slightly in the center of the tip side. It is slantedly slanted, and at the rear left and right sides, a leg 7b having a coupling part 7b 'is formed at the lower end, but the left leg 7b is slightly shorter than the right leg 7b so that the tape is prevented from inclining at an angle. (7), and the above-described tape loosening prevention device (7) is attached to the drum base (8) as shown in Fig. 2 of the accompanying drawings, and the lower drum (1b) having a leader line (1b ') formed on its outer circumference. And the tape release prevention device 7 in the head drum 1 composed of an upper drum 1a mounted on the red shaft 6 and mounted on the drive shaft 10 of the vibration motor 9 on the upper side thereof. The circular hole 7a of the upper end of the upper drum 1a a " " coupling portion 7b 'formed at the lower end of the leg 7b of the tape loosening prevention member 7 to the coupling hole 8a installed in the drum base 8 to prevent the tape loosening prevention mechanism ( 7 is to cover the entire upper peripheral edge (1a ') of the upper drum (1a) constituting the upper drum (1a) constituting the head drum (1).
이와같이 구성된 종래의 테이프 풀림방지장치는 첨부도면 제3도에 도시된 바와같이 상부 드럼(1a)이 전동모터(9)의 구동으로 구동되고 로딩장치(도시되지 않음)에 의해 상부드럼(1a)과 하부드럼(1b)으로 구성되는 헤드드럼(1)에 감기게 된 테이프(5)는 하부드럼(1b)외주연에 형성된 리더라인(1b')을 따라 화살표 방향으로 흘러가게 되고 상부드럼(1a)에 장착된 헤드(6)가 테이프 스캔(Tape Scan)을 하게된다.In the conventional tape loosening prevention device configured as described above, the upper drum 1a is driven by the driving of the electric motor 9 and the upper drum 1a and the loading device (not shown) are shown in FIG. The tape 5 wound on the head drum 1 composed of the lower drum 1b flows in the direction of the arrow along the leader line 1b 'formed on the outer periphery of the lower drum 1b, and the upper drum 1a. The head 6 attached to the tape scan is performed.
상기와같은 상태에서 테이프(5)는 상부드럼(1a)상단 주연에 설치된 테이프 풀림 방지구(7)에 안내되어 상부드럼 상측으로 풀려나가지 않고 원활하게 흐르게 된다.In the above state, the tape 5 is guided to the tape release prevention device 7 provided at the upper edge of the upper drum 1a, and flows smoothly without being released to the upper drum.
그러나 상기한 종래의 테이프 풀림방지장치는 테이프 풀림방지구(7)는 상부드럼(1a)전체를 덮어씌우는 형상이므로 그 가공이 정밀하여야 함은 물론 취부가 어렵고, 헤드(6)를 닦아낼때 많은 불편을 초래하였으며 드럼의 분해결합이 어려울뿐만아니라 원가상승의 한 요인이 되었던 것이다.However, the conventional tape loosening prevention device has a shape that covers the entire upper drum 1a so that the tape loosening prevention device 7 needs to be precisely processed and difficult to install. It was not only difficult to disassemble and disassemble the drum, but also contributed to the cost increase.
본 고안은 상기한 종래의 제결함을 감안하여 상부 드럼의 상단 주연일측에 테이프풀림방지편을 직접 부착함으로서 설치가 보다 용이하며 실사용에 있어서도 편리하도록 함에 그 목적을 둔것으로 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional defects in order to make the installation easier and convenient in practical use by directly attaching the tape release prevention piece to the upper peripheral side of the upper drum. It will be described in detail as follows.
이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.This will be described in detail with reference to the accompanying drawings.
본 고안의 설치상태를 나타낸 사시도인 첨부도면 제4도에 도시된 바와같이 VTR이나 VCR에 설치되는 헤드드럼을 구성하는 상부 드럼(1a)의 상단주연(1a') 일측에 상기 상부드럼(1a)의 주연(1a')보다 외향돌출되도록 테이프 풀림방지편(2)을 설치하되, 상기 테이프 풀림방지편(2)을 "Z"형으로 형성하여 그 선다이 상부 드럼(1a)의 상단 주연보다 외향돌출되도록 상부드럼(1a)이 상면에 스크류(3)로 나합하거나, 첨부도면 제6a도에 도시된 바와같이 상기한 테이프 풀림방지편(2)을 클립형으로 형성하여 상부 드럼(1a) 주연(la') 상단 일측에 내,외로 서로 대향된 요홈(4)을 형성하고, 끝단(2')이 서로 대응되도록 내향절곡된 테이프풀림방지편(2)을 끝단(2)이 상기 요홈(4)에 결합되도록 하여 테이프풀림방지장치를 구성하는 것이다.As shown in FIG. 4 of the accompanying drawings showing the installation state of the present invention, the upper drum 1a is disposed on one side of the upper periphery 1a 'of the upper drum 1a constituting the head drum installed in the VTR or VCR. Install the tape release prevention piece 2 so as to protrude outward from the periphery 1a 'of the tape, and form the tape release prevention piece 2 in a "Z" shape to protrude outward from the top edge of the sun die upper drum 1a. If possible, the upper drum 1a is screwed to the upper surface with a screw 3, or as shown in FIG. 6a of the accompanying drawings, the tape loosening prevention piece 2 is formed in a clip shape so that the periphery la 'of the upper drum 1a is formed. ) Inward and outward grooves (4) formed on the one side of the upper end, and the end (2) coupled to the groove (4) to the end of the tape loosening prevention piece (2) inwardly bent to correspond to each other It is to configure the tape loosening device.
이와같이 상부드럼(1a)의 주연(1a')상단 일측에 상부드럼(1a)과 일체로 테이프풀림방지편(2)을 설치한 본 고안의 사용상태를 첨부도면 제5도에 따라 설명하면, 상부 드럼(1a)이 구동되면서 로딩장치(도시되지 않음)에 의해 상부드럼(1a)과 하부드럼(1b)으로 구성되는 헤드드럼(1)에 감긴 테이프(5)는 하부드럼(1b)의 외주연에 형성된 리드라인(1b')을 따라 화살표 방향으로 홀러가게 되며 이때 상부드럼(12a)에 장착된 헤드(6)가 테이프 스캔(Tape Scan)을 하게된다.As described above according to FIG. 5, the state of use of the present invention in which the tape release preventing piece 2 is integrally installed with the upper drum 1a on one side of the upper edge 1a 'of the upper drum 1a is described. The tape 5 wound around the head drum 1 composed of the upper drum 1a and the lower drum 1b by a loading device (not shown) while the drum 1a is driven is the outer periphery of the lower drum 1b. Hollowed in the direction of the arrow along the lead line (1b ') formed in the at this time, the head (6) mounted on the upper drum (12a) is to perform a tape scan (Tape Scan).
즉, 테이프(5)가 헤드드럼(1)에 감기기 전에 이미 상부드럼(1a)이 회전하게 되며 상부드럼(1a)이 회전하는 상태에서 테이프(5)가 헤드드럼(1)에 감기게 되는 것이다.That is, before the tape 5 is wound on the head drum 1, the upper drum 1a is already rotated and the tape 5 is wound on the head drum 1 while the upper drum 1a is rotated. .
그러므로 상부드럼(1a)의 주연(1a') 상단 일측에 설치된 본 고안인 테이프풀림방지편(2)은 비록 상부 드럼(1a)의 주연(1a') 전체가 아닌 일부분에만 설치되어 있다 하더라도 테이프(5)가 로딩되기전에 이미 상부드럼(1a)이 고속 회전되고 있기 때문에 테이프(5)의 감김을 자연스럽게 안내하게 되며 유사시 테이프(5)가 드럼의 상단으로 넘어가는 것을 방지하게 된다.Therefore, the tape release prevention piece 2 according to the present invention installed on one side of the upper periphery 1a 'of the upper drum 1a, although the tape release prevention piece 2 is installed only on a part of the upper periphery 1a' rather than the entire periphery 1a 'of the upper drum 1a, Since the upper drum 1a is already being rotated at high speed before 5) is loaded, it naturally guides the winding of the tape 5 and, in the unlikely event, prevents the tape 5 from going to the top of the drum.
상기한 바와같이 본 고안은 그 구성이 간단하고 소형이므로 설치가 용이하고 헤드의 청소나 드럼의 분해결합이 손쉬울 뿐만아니라 보다 많은 공간을 활용할 수 있어 콤팩트화함에 일익을 할수 있음은 물론 원가를 절감하는 등 실사용에 있어서도 편리한 것이다.As described above, the present invention is simple and compact in construction, so it is easy to install, easy to clean the head or disassemble and disassemble the drum, and can utilize more space, thereby making it compact and of course reducing the cost. It is convenient in practical use.
