PURPOSE:To direct a chip adequately and to measure its characteristic, by placing a rotating body freely rotatably in a chip conveyance path, and deciding the polarity of the chip. CONSTITUTION:A main device frame 1 is installed at an optional position in the midst of the chip conveyance path, a through hole 3 where the chip (t) stays temporarily is formed in a circular hollow part 2 provided at the center part of the main frame 1, and the circular rotator A is rotated by a pulse motor, etc. When the chip enters the through hole 3 from the chip conveyance path B, the rotator A is rotated to allow both ends of the chip to contact electric contacts D. Then, the polarity and characteristics of the chip are inspected and the rotator A is rotated on the bais of the result to face in an adequate direction, sending the chip to a lower chip conveyance path C. Consequently, the polarities of chips are set uniformly and easily and the characteristics are measured speedily. |
