재물대(b)는 측정하고자 하는 단품의 렌즈가 안치되는 오목부(h)가 형성되어 있고, 오목부(h)에 안치된 렌즈의 둘레를 고정하는 고정부(i)가 형성되어 있다.The stage b has 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 먼저, 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, first, the lens is placed on the stage b, and the barrel e is moved up and down to focus the objective 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 amount of eccentricity of the lens.
