본 고안은 프론트로딩 타입의 자기 기록 재생 장치의 로딩샤프트에 관한 것으로, 특히 구조를 간단화하여 생산성이 우수한 프론트로딩 타입의 자기기록 재생장치의 로딩샤프트에 관한 것이다.The present invention relates to a loading shaft of a front loading type magnetic recording and reproducing apparatus, and more particularly, to a loading shaft of a front loading type magnetic recording and reproducing apparatus having a simplified structure.

종래의 프론트로딩 타입의 VCR(Video Cassette Recorder) 카셋트홀더 구동장치는, 제1도에 도시된 바와같이, 구동모터(1)과, 상기 모터(1)에 연결된 기어트레인(2)과 상기 기어트레인(2)에 의해 회전하는 카셋트 홀더 구동레버 R(3)와 로딩샤프트(7)에 의해 상기 구동레버 R(3)과 연결되어 연동회전 하는 구동레버 L(3')과 카셋트홀더 구동레버(3)내에 고정된 스프링(4)과 카셋트홀더 구동레버(3)의 가이드 홈(13)을 따라 이동하는 카셋트홀더(8)의 고정핀(6)과, 상기 고정핀(6)의 이동을 안내하는 하우징 메인브라켓(12)의 가이드레일(5)로 구성된다.In the conventional front-loading type VCR cassette holder drive device, as shown in FIG. 1, a drive motor 1, a gear train 2 connected to the motor 1, and the gear train are shown. A cassette holder drive lever R (3) rotated by (2) and a drive lever L (3 ') and a cassette holder drive lever (3') interlocked with each other by being connected to the drive lever R (3) by a loading shaft (7). ) And a fixing pin (6) of the cassette holder (8) moving along the guide groove (13) of the spring and the cassette holder driving lever (3) fixed to the inside, and guides the movement of the fixing pin (6) It consists of a guide rail (5) of the housing main bracket (12).

카셋트의 안착과 인출은, 구동모터(1)가 구동되면 모터(1)의 동력이 기어트레인(2)를 통해 카셋트홀더 구동레버R(3)에 전달되어 상기 레버R(3)이 로딩샤프트(7)을 중심으로 회전하여 레버L(3')도 회전하고 카셋트 홀더(8)의 고정핀(6)이 구동레버(3)의 가이드홈(13)과 가이드레일(5)에 구속되어 이동함으로써 이루어진다.When the driving motor 1 is driven, the seating and the drawing of the cassette is transmitted to the cassette holder driving lever R 3 through the gear train 2 so that the lever R 3 is loaded with the shaft. 7) by rotating around the lever L (3 ') and the fixing pin (6) of the cassette holder (8) is restrained by the guide groove (13) and the guide rail (5) of the drive lever (3) Is done.

한편 로딩샤프트(7)은, 제2도에 도시된 바와같이, 일반 쾌삭강재질로서, 양단부가 반원 또는 직사각형의 슬롯팅처리된 슬롯팅부(7a)를 갖고 상기 슬롯팅부(7a)가 구동레버 R, L(3)(3')의 슬롯구멍(3a)(3a')에 강제압입되어 있다.On the other hand, the loading shaft 7, as shown in Figure 2, is a general free-cutting steel material, both ends have a semi-circular or rectangular slotted slotting portion (7a), the slotting portion 7a is a driving lever R, It is forcibly pressed into the slot holes 3a and 3a 'of L (3) 3'.

상기 로딩샤프트(7)의 슬롯팅부(7a)가 사각단면으로 형성된 것을 회전시 슬롯팅부(7a)과 구동레버의 마찰면적을 크게하여 회전슬립을 방지하기 위한 것이다.The slotting portion 7a of the loading shaft 7 is formed to have a rectangular cross section to prevent the rotation slip by increasing the friction area between the slotting portion 7a and the driving lever during rotation.

그런데, 이와같은 종래의 로딩샤프트(7)는 큰 수직하중 또는 수평하중을 받고 있지 않고 있으나, 단가가 비싸고 무게가 무거운 쾌삭강을 재질로 하고 있고 재질이 쾌삭강이므로 부식방지를 위한 표면처리가 요구되는 문제점이 있었다. 또한 종래의 로딩샤프트는 양단부를 회전슬립을 방지하기 위해 슬롯팅 작업을 해야 되는 문제점이 있었다.By the way, the conventional loading shaft 7 is not subjected to a large vertical load or a horizontal load, but since the unit price is expensive and heavy free cutting steel material and the material is free cutting steel, the surface treatment for corrosion prevention is required. There was this. In addition, the conventional loading shaft has a problem that the slotting operation to prevent the rotation slip on both ends.

본 고안의 목적은, 구조가 단순하여 제조가 용이하고 무게가 가볍고 단가가 저렴한 프론팅로딩형 VCR의 카셋트홀더구동레버의 로딩샤프트의 제공에 있다.An object of the present invention is to provide a loading shaft of a cassette holder driving lever of a front-loading-type VCR having a simple structure, which is easy to manufacture, light in weight, and low in cost.

상기 목적을 달성하기 위하여 본 고안의 카셋트홀더구동레버의 로딩샤프트는 단면상 삼각형으로 형성된 한편, 알루미늄 재질로 형성된 것을 특징으로 한다.In order to achieve the above object, the loading shaft of the cassette holder driving lever of the present invention is formed of a triangle in cross section, and is formed of an aluminum material.

이하, 첨부도면에 의거하여 본 고안은 설명한다.Hereinafter, the present invention will be described based on the accompanying drawings.

제3도는 본 고안의 카셋트홀더 구동레버의 로딩샤프트를 나타낸 것으로, 상기 로딩샤프트(7')은 단면상 삼각형으로 형성되며 알루미늄, 특히 AL6063으로 형성된다.Figure 3 shows the loading shaft of the cassette holder drive lever of the present invention, the loading shaft (7 ') is formed in a cross-section triangle and made of aluminum, in particular AL6063.

상기 삼각형의 로딩샤프트(7')은 원형의 압출제품을 수차의 인발가공에 의해 형성될 수 있다.The triangular loading shaft 7 'can be formed by aberration drawing of a circular extruded product.

본 고안의 로딩샤프트(7')는 양단부가 각각 구동레버 R, L(3)(3')의 삼각형구멍(3a)(3a')에 강제압입되어 사용될 수 있다.Both ends of the loading shaft 7 'of the present invention can be used by forcibly pressing the triangular holes 3a and 3a' of the driving levers R and L (3) and 3 ', respectively.

구동모터(1)가 구동되면 모터(1)의 동력이 기어트레인(2)를 통해 구동레버 R(3)에 전달되어 로딩샤프트(7')을 중심으로 회전하면 로딩샤프트(7')에 연결된 구동레버R(3')도 회전하게 된다.When the drive motor 1 is driven, the power of the motor 1 is transmitted to the drive lever R 3 through the gear train 2, and when the drive motor 1 rotates around the loading shaft 7 ′, it is connected to the loading shaft 7 ′. The drive lever R'3 'also rotates.

이때 본 고안의 로딩샤프트(7')는 구동레버 R, L(3')(3')의 구멍(3a')(3a')와 삼각형의 마찰면적을 형성하고 있어 회전슬립을 충분히 방지할 수 있다.At this time, the loading shaft 7 'of the present invention forms a triangular friction area with the holes 3a' and 3a 'of the drive levers R and L (3') and 3 ', thereby sufficiently preventing rotation slip. have.

또한 본 고안의 로딩샤프트(7')은 전체에 걸쳐 삼각형 단면으로 형성되므로, 인발가공만으로 제조될 수 있어, 종래와 같이 별도의 슬롯팅작업이 요구되지 않는다.In addition, since the loading shaft 7 'of the present invention is formed in a triangular cross section throughout, it can be manufactured only by drawing, and no separate slotting operation is required as in the prior art.

또한 본 고안의 로딩샤프트(7')은 알루미늄을 재질로하므로, 종래와 같이 별도의 부식방지를 위한 표면처리가 요구되지 않고 무게가 가볍고 단가를 저감할 수 있다.In addition, since the loading shaft 7 'of the present invention is made of aluminum, it does not require a separate surface treatment for preventing corrosion as in the prior art, it is light in weight and can reduce the unit cost.

이상과 같이 본 고안에 따르면 로딩샤프트를 전체에 걸쳐 단면상 삼각형으로 형성하고 재질을 알루미늄으로 함으로서, 별도의 슬롯팅작업이 요구되지 않고 인발작업만으로 제조할 수 있어 생산성이 향상되고 또한 부식 방지를 위한 표면처리가 요구되지 않고 무게가 가볍고 생산단가를 저감할 수 있는 효과가 있다.As described above, according to the present invention, the loading shaft is formed in a triangular cross-section and the material is made of aluminum, so that a separate slotting operation is not required. No treatment is required, and the weight is light and the cost of production can be reduced.
