PURPOSE:To perform measurement efficiently with improved reliability by measuring an object to be measured in two states, erected and inverted states, by a constitution wherein the object is held by a self-aligning holding device with insulation members arranged therein and the holding device is inverted. CONSTITUTION:A holding element 10 holding an object to be measured consists of holding plates 11 arranged opposite to each other and of insulation members 12 and 13 arranged so as to insulate the holding plates 11 electrically from other parts, and an opening lever 14 controlling the opening of the holding plates 11 by shaking is connected thereto through the intermediary of a power transmission mechanism, whereby a holding unit 15 is constituted. The holding unit 15 is connected to an inverting unit 20 containing an inversion rod 22 and a positioning cam 21, and when the holding element is inverted at an angle of 180 deg., a steel ball 24 enters one of grooves 23 provided at two opposite places of the positioning cam 21, and thereby the holding element is positioned. Since the object to be measured can be inverted for measurement while it is held by the holding unit 15, the measurement thereof can be made efficient and the reliability of the measurement can be improved. |
