Abstract: A carrier tape feeder is provided. The carrier tape feeder includes a unit for loading a carrier tape, a picking-up unit where chips are picked up, and a driving unit. The pick-up unit includes a knife portion, a folding-guiding portion, and an inversion-guiding portion. The knife portion separates a cover tape from a base tape in a first adhesive portion. The folding-guiding portion is spaced from one lateral side of the knife portion to induce folding of the cover tape separated by the knife portion in the lengthwise direction in a state in which the cover tape is partially attached to the base tape in a second adhesive portion. The inversion-guiding portion extends in an oblique direction from the knife portion and the folding-guiding portion toward the outside of the carrier tape to induce inversion of the upper and lower surfaces of the cover tape folded in the folding-guiding portion so as to be superimposed on the base tape.
