Abstract: Controller executes a first scanning control, causing a driver to move a probe such that a tip scans along an inclined surface of a V groove to approach a center of the V groove, and a second scanning control, causing the driver to move the probe such that the tip scans along the inclined surface of the V groove to approach the center of the V groove from a side opposite that of the first scanning control. Angle calculator calculates an angle created between a direction of a deflection vector of the probe and a predetermined direction. Threshold value-correspondent coordinate obtainer obtains coordinates of the tip where the angle has changed to exceed a first threshold value during execution of the first scanning control and obtains coordinates of the tip where the angle has changed to exceed a second threshold value during execution of the second scanning control.
