Abstract:
1. A tape feeder that sequentially supplies electronic components to a pick-up position where the electronic component is picked up by a transfer head by pitch-feeding a carrier tape that holds the electronic components in component storage recesses, the tape feeder comprising: a body portion in which a tape travel path guiding the carrier tape is formed, the carrier tape including a base tape on which the recesses are formed and a cover tape adhering to an upper surface of the base tape so as to cover the recesses; a tape feed mechanism that is provided in the body portion and pitch-feeds the carrier tape at a predetermined pitch by intermittently rotating a sprocket when feed pins of the sprocket are engaged with feed holes formed on the base tape; a guide section that is detachably mounted on the body portion, guides the width direction of the carrier tape fed by the tape feed mechanism in a predetermined range including the pick-up position on the body portion, presses the carrier tape from above by a guide surface to guide an upper surface of the carrier tape, and supports and guides a lower surface of the carrier tape; and a cover tape separating mechanism that is provided in the guide section, and exposes the electronic components stored in the recesses by separating the cover tape from one side portion of the base tape on which the recesses are formed, wherein the cover tape separating mechanism includes a separating member that separates an adhering surface from the one side portion in a separation target range, which includes at least the recesses, by being interposed between the base tape and the adhering surface of the cover tape during the pitch-feeding of the carrier tape, the cover tape is folded in half on the base tape in a flat shape to be in parallel with the base tape at the pick-up position by bending one side portion of the cover tape, which is separated from the base tape by the separating member, toward the other side portion and pressing the bent cover tape against a guide surface of the guide member from below while guiding the carrier tape to the pick-up position, and a bending degree of the cover tape is increased by an upward movement of the base tape pushed by a portion of the guide section.
