Abstract:
An attitude changing apparatus for changing the attitude of an electronic chip, the apparatus comprising:a rotor including cavities on the outer periphery of the rotor, the cavities contain and hold electronic chips, wherein a part of the electronic chips projects over an outside portion of the rotor; a base supporting the rotor; driving means for rotationally driving the rotor in a predetermined direction; and a chip guide placed at a fixed position close to the outer periphery of the rotor, the chip guide includes a continuously twisted guide face for making sliding contact with the projecting portions of the electronic chips held in the cavities so as to turn the attitudes of the electronic chips by 90Â°, wherein the guide face and an upper surface of the base are initially co-planar to load the electronic chips with minimal disturbance.
