    • PURPOSE:To inspect easily and quickly a stylus by sliding the stylus, which is held mounted to a tester in the same way as in the stage of measurement, in the direction at a right angle to the ridgeline while bringing the same into contact with a stationary knife edge and knowing the shape and radius of curvature at the tip of the stylus. CONSTITUTION:A sharp knife edge 4 of which the radius of curvature at the tip is as small as to be negligible as compared to the radius of curvature at the tip of a stylus is fixed to a measuring base 7 of a surface roughness tester 8. A stylus 9 mounted to an arm 8a is moved beyond a ridgeline 4a in a direction at a right angle thereto in press contact with both slopes of the knife edge. The shape and radius of curvature at the top of the stylus 9 are known in accordance with the magnified recording figure drawn by the device 8. The inspection is thus accomplished easily and quickly in the mounted state.
    • 目的:通过以与测量阶段相同的方式将测量仪固定在测试仪上的触控笔以与脊线成直角的方向滑动,同时使其与 固定的刀刃,并且知道触针尖端的形状和曲率半径。 构成:尖头的曲率半径与触笔尖端的曲率半径相比可以忽略的锋利的刀刃4固定在表面粗糙度测定器8的测量基座7上。 安装在臂8a上的触针9在刀刃的两个斜面上与其成直角的方向移动超过脊线4a。 触针9顶部的形状和曲率半径根据由装置8绘制的放大的记录图形是已知的。因此,检查在安装状态下容易且快速地完成。
