The pin fixing unit includes a stage fixing unit(41) formed on a side, a bracket(42) having a shaft and a bearing, a rotatable bar(46) having a pin fixing hole accepting a pin(45), a weight(46a) coupled with a screw(46b), and a sensor(47) for measuring contact between the pin and a test piece. A display has a video output unit and a data output unit for outputting the detected signals as video signals and data at the same time. To observe friction and wear in the SEM, the pin is contacted with a disk at a desired position and a disk driver is operated. As the disk is rotated, the test piece on the disk is rotated at low speed to generate frictional force. The pin is moved according to a specific angle of the disk having the test piece thereon. Thereby, the shape of a desired part is observed easily.
