본 고안은 VTR용 드럼의 피지(Puls Generator)검출장치 설치구조에 관한 것으로, 특히 드럼의 외부에서 피지를 검출하도록 개선하여, 드럼부품 가공시 가공위치 치수관리상의 어려움을 해결하고, 조립공정상의 편리성을 제공토록 함에 주안점을 둔 것이다.The present invention relates to the installation structure of the pulse generator detection device of the drum for the VTR, and in particular, to improve the detection of sebum from the outside of the drum, to solve the difficulty in controlling the processing position dimensions when processing the drum parts, convenient in the assembly process The focus is on providing sex.

종래의 피지검출장치를 보면 도면 제1도, 제2도, 제3도에서와 같이, 하드럼(1)의 하측에 기판(3)과 고터 스테이터(31)가 스크류로서 고정되고, 하드럼(1)을 관통 설치된 샤프트(2)의 하부에 삽입 조립된 링칼라(4) 하측에 모터로터(7)가 스크류로 고정 결합되었다.In the conventional sebum detection apparatus, as shown in FIGS. 1, 2, and 3, the substrate 3 and the goter stator 31 are fixed as screws under the hard rum 1, and the hard rum ( The motor rotor 7 was fixedly screwed under the ring collar 4 inserted into the lower part of the shaft 2 installed through 1).

그리고, 기판(3) 저면 일측의 로터 측방에는 피지헤드(8')가 고정 설치되었고, 로터(7)의 외주면 양측에 피지 마그네트(9')가 고정 설치되어 있다.And the sebum head 8 'is fixed to the rotor side of the bottom side of the board | substrate 3, and the sebum magnet 9' is fixed to the outer peripheral surface of the rotor 7 at both sides.

이때, 피지헤드(8')는 모터 스테이터카 하드럼에 조립될때 일정한 각도로 조립되어야 하며, 피지 마그네트(9')는 로터의 외주면에 상호 180°간격을 유지하여 부착되어야 하고, 모터로터(7)를 체결하기 위한 구멍은 피지 마그네트(9')와 일정한 각을 유지하고 가공되어야 한다.At this time, the sebum head 8 'should be assembled at a certain angle when assembled to the motor stator car hard rum, and the sebum magnet 9' should be attached to the outer circumferential surface of the rotor at 180 ° intervals, and the motor rotor 7 The hole for fastening) should be machined at a constant angle with sebum magnet 9 '.

그리고, 후렌지(11)에 가공된 상드럼 체결구멍(12)과, 링칼라(4)에 가공된 구멍(10)이 일정한 각을 유지하여, 여기에 모터로터를 피지 마그네트와 각을 유지하며 가공된 구멍을 일치시켜 조립하므로서 조립이 완료된다.The upper drum fastening hole 12 processed in the flange 11 and the hole 10 processed in the ring collar 4 maintain a constant angle, and the motor rotor is processed while maintaining the angle with the sebum magnet. Assembly is completed by matching the assembled holes.

따라서, 모터로터(7)가 회전하면, 그에 부착된 피지 마그네트(9)가 피지 헤드(8')를 근접한 거리에서 스처지나 가면서 신호를 발생시켜, 상드럼에 장착된 비디오 헤드가 테이프를 스캔하여 A, B트렉을 번갈아 읽어 신호를 읽어낼수 있도록 스위칭하여준다.Therefore, when the motor rotor 7 rotates, the sebum magnet 9 attached thereto will pass through the sebum head 8 'at a close distance to generate a signal, and the video head mounted on the drum will scan the tape. Switch to read A and B tracks alternately.

그런데, 상기와 같은 종래의 피지 검출장치는, 하드럼 결합체를 조립할 경우 조립 지그에 후렌지 가공된 구멍을 맞추고, 상측의 링킬라 구멍이 후렌지와 일정한 각도를 정확하게 유지하기 위하여 상측 및 하측의 링칼라, 후렌지의 구멍을 정확히 가공하고, 또 조립을 위한 지그 자체도 정확하게 각도의 정확성을 위해 정밀하게 제작되어야 하며, 조립시에는 하나하나 세심하게 조립해야 하는 등으로 인하여, 조립시 많은 시간이 걸리고, 불필요한 구멍가공을 수반해야 하는 등의 문제점이 있었다.By the way, in the conventional sebum detection device as described above, when assembling the hard rum assembly, the flanged holes are aligned with the assembling jig, and the upper ring-killar holes have upper and lower ring collars to accurately maintain a constant angle with the flanges. The hole of the flange is precisely processed, and the jig for assembling itself must be made precisely for the accuracy of the angle, and assembling requires careful assembly one by one, etc. There was a problem that the process must be accompanied.

따라서, 본 고안은 종래의 위와같은 치수관리 및 정밀가공 조립상의 문제점을 해결하기 위하여, 모터부에 위치하던 피지 마그네트와 피지 헤드를 없에고 별도의 취부 장치를 이용하여 상드럼의 상측에 설치한 것으로, 이를 첨부된 도면에 의거 상세히 설명하면 다음과 같다.Therefore, the present invention is installed in the upper side of the upper drum using a separate mounting device without the sebum magnet and sebum head located in the motor in order to solve the problems of the conventional dimension management and precision processing as described above, This will be described in detail with reference to the accompanying drawings.

즉, 피지헤드와 피지 마그네트가 결합된 검출장치를 구성함에 있어서, 도면 제7도에서와 같이 피지헤드(8)의 상측 주위에 몰드몰(15)을 감싸줌과 동시, 그 상측에 ㄱ형 걸림핀(151)을 형성하였다.That is, in constructing a detection device in which the sebum head and the sebum magnet are combined, as shown in FIG. 7, the mold mould 15 is wrapped around the upper side of the sebum head 8 and at the same time, the a-shaped locking pin ( 151).

그리고, 제8도에서와 같이 피지 마그네트(9)의 하측 주위에 몰드몰(18)을 감싸고, 그 하방에 몰드붕(181)을 형성하였다.Then, as shown in FIG. 8, the mold mould 18 was wrapped around the lower side of the sebum magnet 9, and a mold shelf 181 was formed below the mold mould.

이상과 같이 하여, 도면 제6도, 제9도에서와 같이 피지 마그네트(9)는 몰드봉(181)을 이용하여 상드럼(14) 상측면 양측의 헤드 조정용 구멍(20)에 끼워 안착시키고, 피지헤드(8)는 상측의 걸림핀(15)을 드럼 조립체의 정전기 방지를 위해 데크(21)와 드럼 샤프트(2)간을 연결 접촉시키는 부품인 브라켓 브러시 조립체의 브라켓(19) 일측 부분에 끼워 주므로서 조립이 완료되는 것으로, 도면중 미설명 부호 5, 6은 스크류이다.As described above, as shown in Figs. 6 and 9, the sebum magnet 9 is inserted into the head adjusting holes 20 on both sides of the upper side of the upper drum 14 by using a mold rod 181, The sebum head 8 is fitted to one side of the bracket 19 of the bracket brush assembly, which is a component for connecting the upper engaging pin 15 between the deck 21 and the drum shaft 2 to prevent static electricity of the drum assembly. The assembly is completed by giving, and reference numerals 5 and 6 in the drawings are screws.

그리고, 상기 피지헤드 조립체의 신호선(17)은 브라켓(19)을 타고 회로기판으로 연결된다.The signal line 17 of the sebum head assembly is connected to the circuit board by the bracket 19.

이상과 같이 구성되고 결합 설치된 본 고안은, 테이프 주행시 하측의 모터 장치에 의해 상드럼(14)이 회전하면서 테이프의 A, B트랙을 스캔할때, 피지헤드(8)와 피지 마그네트(9)가 스처지나면서 신호를 발생하며, 발생된 신호는 신호선을 타고 회로기판으로 전달됨에 따라, 회로기판에서 A, B신호 스위칭을 하여 화면을 보여주게 되는 것 이다.The present invention constructed and coupled as described above has the sebum head 8 and sebum magnet 9 when the upper drum 14 is rotated by the lower motor device while the tape travels, and the A and B tracks of the tape are scanned. As it passes through, it generates a signal. As the generated signal is transferred to the circuit board by taking a signal line, the A and B signals are switched on the circuit board to show a screen.

이상과 같이, 피지헤드와 피지 마그네트가 몰드몰을 이용하여 상드럼과, 그 상측의 브라켓에 결합 설치되므로서, 드럼 조립체 조립시 상측 후렌지와 하측의 링칼라를 정밀한 각도로 맞출 필요가 없어지고 어떤 각도로 조립하여도 무방하고, 또한 모터에도 피지마그네트를 장착하지 않게 되면서 정확한 각도 유지를 위하여 구멍가공을 정확하게 할필요가 없어졌으며, 모터기관의 구조가 간단해 졌는바, 이상의 모든 조건으로 인하여 부품의 가공성이 좋아지고, 조립속도가 매우 빨라졌으며, 외부에서 피지헤드와 마그네트를 간단하게 조립 설치하므로서 월등한 생산성을 꾀할수 있는 특출한 효과가 있는 것이다.As described above, since the sebum head and sebum magnet are attached to the upper drum and the bracket on the upper side by using a mold mole, the upper flange and the lower ring collar need not be aligned at a precise angle when assembling the drum assembly. Since it can be assembled at an angle, and the sebum magnet is not installed on the motor, it is not necessary to precisely drill holes for maintaining an accurate angle, and the structure of the motor engine has been simplified. Processability is improved, the assembly speed is very fast, and the sebum head and the magnet are easily assembled and installed from the outside, which is an extraordinary effect to achieve superior productivity.
