PURPOSE:To perform a large capacity treatment of IC and contrive the improvement of operating rate, by preventing the operating speed righ and left of shuttles from not following the measured speed in an auto handler wherein the shuttle and containing part have the structure of at least two stages or more. CONSTITUTION:An IC to be measured is thrown into a supply part 15. Next, the IC is sent in a transverse direction by a carrier 16, and the IC sent from the carrier part is turned at a turret 17 in the direction of a vertical measurement part, thus being dropped thereinto. Further, it is judged for PASS, FALL at the measurement part 18 and sent into a shoot part 19. In case of the operating speed of the shuttle <measured speed, the shoot part 19 rises and falls and then utilizes the first and second shuttles 20, 21 and containing parts 22, 23. In brief, when the measured speed is considerably high and the classification in the shuttle is difficult, the IC is carried alternately into an unused shuttle 19 by the up-down movement of the shoot part so that the shuttle 19 can satisfactorily cope with the measured speed in the measurement part. |
