    • PURPOSE:To derive a sectional area easily, swiftly and at a low cost, by using a known contact to an interpoint distance contacting with both wall surfaces of a groove, detecting the displacement in the direction of depth of the groove, and executing the operation processing. CONSTITUTION:A contact 4 having the width (a) of a tip of a stroke bar 5 is made to contact with both wall surfaces of a groove, the extent of displacement (x) of the stroke bar 5 is detected, its value is provided to an operation processing part 7, and a sectional area is calculated in accordance with the mensuration. In this way, the sectional area is derived easily, swiftly and also at a low cost.
    • 目的:通过使用与沟槽的两个壁面接触的间隔距离的已知接触,检测凹槽的深度方向上的位移,并且执行操作,以容易,快速和低成本地导出截面积 处理。 构成:使具有行程杆5的前端的宽度(a)的触点4与槽的两个壁面接触,检测行程杆5的位移(x)的程度,提供其值 到操作处理部7,并且根据测量计算截面面积。 以这种方式,截面积很容易,迅速地并且也以低成本得出。
