본 발명은 갬코더용 경통에 취부되는 렌즈의 편심을 측정장치에 관한 것으로, 특히 다수의 렌즈가 취부되어 있는 리어배럴(REAR BARREL)을 회전시키면서 렌즈의 편심을 정밀하게 측정하는 리어배럴 편심측정지그에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a measuring device for measuring an eccentricity of a lens mounted on a barrel for a camcorder, and in particular, a rear barrel eccentric measuring jig for precisely measuring the eccentricity of a lens while rotating a rear barrel (REAR BARREL) in which a plurality of lenses are mounted. It is about.

제1도에 도시된 바와 같이, 현미경과 비슷한 형태를 갖고 있는 종래의 렌즈편심측정장치(a)는 측정하고자 하는 렌즈를 고정하는 재물대(b)와, 재물대(b)에 놓여진 렌즈의 편심을 측정하기 위해 대물렌즈(c)와 접안렌즈(d)가 설치되어 있고, 상,하로 이동되는 경통(e)과, 재물대(b)와 경통(e)을 지지하는 프레임(f)과, 프레임(f)을 지지하는 받침대(g)로 구성되어 있다.As shown in FIG. 1, a conventional lens eccentric measuring apparatus (a) having a shape similar to a microscope measures the eccentricity of the lens stage (b) for fixing the lens to be measured and the lens placed on the stage (b) For this purpose, an objective lens (c) and an eyepiece (d) are provided, and the barrel (e) to be moved up and down, the frame (f) to support the material stage (b) and the barrel (e), and the frame (f) ) Is composed of a pedestal (g) for supporting.

재물대(b)는 측정하고자 하는 단품의 렌즈가 안치되는 오목부(h)가 형성되어 있고, 오목부(h)에 안치된 렌즈의 둘레를 고정하는 고징부(i)가 형성되어 있다.The stage b is formed with a recess h in which a single lens to be measured is placed, and a fixing part i for fixing a circumference of the lens placed in the recess h is formed.

따라서, 렌즈의 편심을 측정할 때에는 먼지, 렌즈를 재물대(b)에 올려놓은 다음 경통(e)을 상,하로 이동시켜 대물렌즈(c)의 촛점을 맞춘다.Therefore, when measuring the eccentricity of the lens, dust, the lens is placed on the stage (b) and then the barrel (e) is moved up and down to focus the objective lens (c).

그리고, 대물렌즈(c)에 표시된 눈금과 일치되는 값을 읽으면 이 측정 값이 렌즈의 일방향 편심량이 된다.When the value coinciding with the scale indicated on the objective lens c is read, the measured value is the one-way eccentricity of the lens.

그러나, 이와 같이 구성되어 렌즈의 편심량을 측정하는 종래의 편심측정지그는 렌즈의 일방향 편심량을 측정한후 또다른 방향의 편심량을 측정하고자 할때 고정부(h)를 해제시킨 다음 소정각도로 렌즈의 방향을 바꾸어 주고 다시 렌즈를 고정부(h)로 고정시켜 주어야 하므로 편심측정작업이 신속하게 이루어지지 않는 문제점이 있었다.However, the conventional eccentric measuring jig configured as described above to measure the amount of eccentricity of the lens is to measure the direction of the lens at a predetermined angle after releasing the fixing part h when measuring the amount of eccentricity in another direction after measuring the eccentricity of the lens There was a problem that the eccentric measurement operation is not made quickly because the change and give the lens fixed to the fixed portion (h) again.

또한, 다수의 렌즈가 설치되어 있는 경통(e)의 리어배럴 편심량을 측정하고자 할때, 고정부(b)가 단품 렌즈만 고정시킬 수 있게 되어 있으므로 리어배럴에 설치되는 렌즈의 편심량을 측정하는 편심측정시간도 많이 걸리는 문제점이 있었다.In addition, when measuring the amount of rear barrel eccentricity of the barrel (e) in which a plurality of lenses are installed, the fixing part (b) can fix only the single lens, so that the amount of eccentricity of the lens installed in the rear barrel is measured. There was a problem that takes a lot of measurement time.

본 발명은 상기의 이와 같은 문제점을 해소시키기 위하여 안출한 것으로서, 리어배럴을 지지하는 재물대를 회전시킴으로써 재물대에 고정된 렌즈의 편심방향을 간단히 검사할 수 있고, 캠코더의 경통을 구성하고 다수의 렌즈가 설치되어 있는 리어배럴을 재물대로 지지할 수 있게 하여 다수의 렌즈가 설치된 리어배럴의 렌즈편심량을 정밀하게 그리고 신속히 측정할 수 있는 리어배럴 편심측정지그를 제공하는 것이 목적이다.The present invention has been made to solve the above problems, and by rotating the stage supporting the rear barrel, the eccentric direction of the lens fixed to the stage can be easily inspected, and the barrel of the camcorder constitutes a plurality of lenses.

연결부(12)의 타단부는 편심현미경의 본체에 연결하기 위한 나사(12)가 외측에 형성되어 있다.The other end of the connecting portion 12 is formed with a screw 12 on the outside for connecting to the main body of the eccentric microscope.

또한, 재물대(15)의 하부 둘레에는 재물대(15)를 회전시킬 때 미끄러짐을 방지하도록 널링(KNURLING)부(15)가 형성되는 것이 바람직하다.In addition, it is preferable that a knurling portion 15 is formed around the lower portion of the stage 15 to prevent slipping when the stage 15 is rotated.

제3도에 도시된 바와 같이, 리어배럴 편심측정장치는 경통을 회전시킴과 동시에 고정하는 편심측정지그(10)와, 재물대(16)에 놓여진 렌즈의 편심을 측정하기 위해 대물렌즈(41)와 접안렌즈(42)가 설치되어 있고 상,하로 이동되는 경통(44)과, 재물대(16)와 경통(44)을 지지하는 프레임(40)과, 프레임(40)을 지지하는 받침대(43)로 구성되어 있다.As shown in FIG. 3, the rear barrel eccentricity measuring device includes an eccentricity measuring jig 10 for rotating and fixing the barrel and an objective lens 41 for measuring the eccentricity of the lens placed on the stage 16. Eyepieces 42 are provided and the barrel 44 to move up and down, the frame 40 for supporting the stage 16 and the barrel 44, and the pedestal 43 for supporting the frame 40 Consists of.

제4도에 도시된 바와 같이, 캠코더의 경통은 리어배럴(도시되지 않음)과 리어배럴(REAR BARREL)(20)로 구성되어 있다.As shown in Fig. 4, the barrel of the camcorder is composed of a rear barrel (not shown) and a rear barrel (REAR BARREL) 20.

리어배럴(20)의 내부에는 다수의 렌즈(2l)가 설치되어 있고, 리어배럴(20)의 하단부에는 씨씨디(CCD)가 정밀하게 조립되도록 내경면(16)이 정밀하게 가공되어 있다.A plurality of lenses 2l are provided inside the rear barrel 20, and the inner diameter surface 16 is precisely processed at the lower end of the rear barrel 20 so that the CD is precisely assembled.

연결부(12)의 하부는 회전되지 않도록 베어링(11)의 내측에 압입고정되어 있다.The lower part of the connection part 12 is press-fitted inside the bearing 11 so that it may not rotate.

이하, 본 발명의 작용, 효과를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.Hereinafter, the operation and effects of the present invention will be described in detail with reference to the accompanying drawings.

본 발명의 리어배럴 편심측정지그(10)는 리어배럴(20)을 지지하는 재물대(15) 하부에 베어링(11)을 압입시켜서 재물대(15)가 회전되게 고정한 다음 베어링(11) 내측에 베어링(11)을 지지함과 동시에 프레임(4)에 고정되는 연결부(12)를 또한 압입시켜 연결부(12)를 회전되지 않도록 고정한다.The rear barrel eccentric measuring jig 10 of the present invention press-fits the bearing 11 to the lower portion of the stage 15 for supporting the rear barrel 20 so that the stage 15 is fixed to rotate, and then the bearing (11) inside the bearing (11). At the same time as supporting 11, the connection part 12 fixed to the frame 4 is also press-fitted to fix the connection part 12 so as not to rotate.

그리고, 연결부(12)의 하단부에 형성된 나사(13)를 프레임(40)에 결합시켜 고정시키면 베어링(11) 외측에 압입고정된 재물대(15)만 회전된다.In addition, when the screw 13 formed at the lower end of the connecting portion 12 is fixed to the frame 40, only the stage 15 that is press-fitted and fixed to the outside of the bearing 11 is rotated.

이때, 리어배럴(20)을 재물대(15)의 원형지지기둥(16)에 끼우면 리어배럴(20)의 밑면은 리어배럴 편심측정지그(10)의 재물대(15)와 원형지지기등(16)에 접촉된다.At this time, when the rear barrel 20 is inserted into the circular support column 16 of the stage 15, the bottom of the rear barrel 20 is the stage 15 and the circular support 16 of the rear barrel eccentric measurement jig 10 Is in contact with.

이와 같이 놓여진 리어배럴(20)의 편심을 측정할 때, 널링부(14)를 손으로 천천히 돌려주면 베어링(11)에 압입고정된 재물대(15)가 회전되므로 리어배럴(20)에 설치된 다수의 렌즈(21)들의 편심량을 한번에 측정할 수 있다.When measuring the eccentricity of the rear barrel 20 placed in this way, if the knurled portion 14 is slowly rotated by hand, the stage 15 that is press-fit and fixed to the bearing 11 is rotated, so that a plurality of installed in the rear barrel 20 The amount of eccentricity of the lenses 21 can be measured at a time.

상기와 같이 구성되어 리어배럴(20)을 지지하는 본 발명의 리어배럴 편심측정지그(10)는 리어배럴(20)에 설치된 다수의 렌즈(21)를 하나씩 독립적으로 측정하여야 하는 종래의 방식과 달리 리어배럴(20)을 직접 회전하는 재물대(15)에 올려놓아 재물대를 회전시키면서 여러방향의 편심량을 계속하여 측정함으로써 렌즈(21)의 편심량을 간단하고 정밀하게 측정할 수 있는 효과를 갖는 유용한 발명이다.Unlike the conventional method in which the rear barrel eccentric measurement jig 10 of the present invention configured as described above to support the rear barrel 20 independently measures a plurality of lenses 21 installed on the rear barrel 20 one by one. It is a useful invention having the effect of simply and precisely measuring the amount of eccentricity of the lens 21 by continuously measuring the amount of eccentricity in various directions while placing the rear barrel 20 on the directly rotating stage 15. .
