⊙ 비디오 테이프카세트의 지지가 불안정하게 되므로 측정시 유동발생의 우려가 커서 취급의 불편하고, 측정치의 신뢰도가 저하되는 것이며,⊙ As the support of the video tape cassette becomes unstable, there is a risk of flow during measurement, which is inconvenient to handle and the reliability of the measured value is deteriorated.
⊙ 인력으로 측정봉(22)을 눌러주는 것이므로 가압력이 일정치 않게되고 미세이동이 불가능하여 측정치의 정밀도가 저하되는 것임은 물론 측정봉(22)이 릴지지스프링에서 자주 이탈되는 것이며,⊙ Pressing the measuring rod 22 with manpower, the pressing force becomes inconsistent and fine movement is impossible, so that the precision of the measured value is lowered, and the measuring rod 22 is frequently released from the reel support spring,
⊙ 상기 이유로 인하여 숙련된 측정요원만이 작업을 수행할 수 있게 되는 것으로 측정작업에 있어 취급자의 적용범위가 협소하게 되는 것이었다.⊙ For the above reasons, only trained measuring personnel could perform the work, which narrowed the scope of coverage of the handling personnel.

* 도면중 미설명부호 (10)(10')은 릴지지스프링이고, (11)는 조작패널을 보인 것이다.* In the drawings, reference numerals 10 and 10 'denote reel support springs, and 11 denotes an operation panel.
이와 같이 구성되는 본 고안의 작용효과를 상세히 설명하면 다음과 같다.If described in detail the effect of the present invention is configured as follows.
본 고안의 삽지홈(9)은 8㎜ 비디오 테이프카세트의 전체길이에서 상부체(US)에 고정되는 양 릴지지스프링(10)(10')의 설치간격을 더한 길이를 갖도록 구성되는 것으로 상부체(US)를 앞쪽으로 당겨 붙이면 뒷쪽의 릴지지스프링(10')이 측정봉(8D)의 직하방에 위치되고 반대로 뒷쪽으로 밀어 붙이면 앞쪽의 릴지지스프링(10)이 측정봉(8D)의 직하방에 위치되는 것으로 상부체(US)를 인출시키지 않고도 직진이동만으로 측정 포인트를 정확하게 세팅시켜 줄 수 있게 되는 것이다.Insertion groove 9 of the present invention is configured to have a length plus the installation interval of both the reel support spring (10, 10 ') fixed to the upper body (US) in the overall length of the 8mm video tape cassette Pull (US) forward to attach the rear reel support spring 10 'directly below the measuring rod 8D. Conversely, push the back to the front reel support spring 10 directly below the measuring rod 8D. Since it is located in the room, it is possible to accurately set the measuring point by moving straight without drawing the upper body US.
도 1 및 도 2 에서와 같이 구성되는 본 고안을 이용하여 릴지지스프링(10)(10')의 탄성력을 측정하기 위해서는 먼저 릴지지스프링(10)(10')이 위로 노출 되도록 삽지홈(9)에 상부체(US)를 집어 넣어 어느 한쪽으로 밀어붙인 다음 노브(5)를 회전시키면 랙기어부(3)에 치합된 피니언기어(4)(4')가 회전되면서 이동거리 측정기(6)와 탄성측정기(8)를 서서히 하강시키게 되는 것으로 측정봉(8D)의 하단이 릴지지스프링(10')을 설정된 깊이로 눌러줄 때 까지 하강이 계속되는 것이며 이때 이동거리 측정기(6)의 높낮이 표시부(7)에는 소정의 기준 치수면을 기준으로 측정봉(8D)의 이동거리가 연산되어 표시되는 것으로 릴지지스프링(10')을 일정하고 정확한 깊이로 가압시켜 줄 수 있게 되는 것이다.In order to measure the resilient force of the reel support springs 10 and 10 'by using the present invention configured as shown in FIGS. 1 and 2, the insertion grooves 9 are first exposed so that the reel support springs 10 and 10' are exposed upward. Put the upper body (US) in the and push it to either side, and then rotate the knob (5) to rotate the pinion gear (4) (4 ') engaged with the rack gear portion (3), the movement distance measuring instrument (6) And the elasticity measuring instrument 8 is gradually lowered. The lowering continues until the lower end of the measuring rod 8D presses the reel support spring 10 'to the set depth. At this time, the height display part of the moving distance measuring instrument 6 In 7), the movement distance of the measuring rod 8D is calculated and displayed on the basis of a predetermined reference dimension surface so that the reel support spring 10 'can be pressed to a constant and accurate depth.
이와같이 측정봉(8D)이 접촉되면 릴지지스프링(10')의 탄발력이 측정봉(8D)을 거쳐 탄성측정기(8)의 로드셀(8B)에 의해 측정되어 탄성치 표시부(8C)에 디지탈 방식으로 표시되는 것이다.In this way, when the measuring rod 8D comes into contact with each other, the resilient force of the reel support spring 10 'is measured by the load cell 8B of the elastic measuring instrument 8 via the measuring rod 8D, and the elastic value display unit 8C is digitally connected. Is displayed.
한편 미측정상태의 나머지 릴지지스프링(10)을 측정하기 위해서는 노브(5)를 회전시켜 측정봉(8D)을 상승시킨 다음 상부체(US)를 상기의 반대쪽으로 이동시켜 벽에 밀착시켜 미측정상태의 릴지지스프링(10)이 측정봉(8D)의 직하방에 위치되도록 한 다음 상기와 동일한 동작으로 탄성력을 측정하면 되는 것이다.On the other hand, in order to measure the remaining reel support spring 10 in the unmeasured state, the knob 5 is rotated to raise the measuring rod 8D, and then the upper body US is moved to the opposite side of the above to be in close contact with the wall. The reel support spring 10 in a state is to be positioned directly below the measuring rod 8D, and then the elastic force is measured by the same operation as described above.
이상과 같은 본고안은 비디오 테이프카세트의 상부체가 삽지홈에 끼워져 안정된 지지상태를 이루게 되는 것이므로 측정시 유동발생의 우려가 전혀 없게 되므로 취급의 편의성이 향상되고 측정치의 신뢰도가 크게 개선되는 것이며, 기계적인 구조를 이용하여 일정한 방향과 압력으로 미세이동이 가능하게 측정봉을 눌러주게 되는 것이므로 측정봉이 릴지지스프링에서 이탈됨이 없으며 측정치의 정밀도를 향상시킬 수 있게 되는 것이며, 비숙련된 자라도 용이하게 측정작업을 수행할 수 있게 되는 효과가 있는 것이다.As described above, since the upper part of the video tape cassette is inserted into the insertion groove to achieve a stable support state, there is no fear of flow during measurement, thereby improving the convenience of handling and greatly improving the reliability of the measured value. Using the structure, it is possible to press the measuring rod to move finely in a certain direction and pressure, so that the measuring rod does not deviate from the reel support spring and improves the accuracy of the measured value. There is an effect that can be performed.
