PURPOSE:To prevent erroneous classification due to two falls by the constitution wherein a part of a lead support is made to be a ground potential, and an electrode measuring probe is contacted with the part of the lead support and becomes the ground potential when two objects to be measured fall. CONSTITUTION:Two electronic parts 1 pass an individual feeding mechanism 5 and enter a measuring position 6. The electrode measuring probe 7 has a cut out part which contacts a lead 8 of the second electronic part 12. The probe 7 is contacted with a conductor 14 of the lead support 9, which is at the ground potential, and it becomes the ground potential. Therefore the applied voltage is not supplied to the first electronic part 13. General electric characteristics are judged to be bad. A classifying chute 10 is moved to a bad part containing box. Two electronic parts 1 are put in the bad part containing box.
