Abstract: A tape feeder feeds a component supply tape including a cover tape adhered on a carrier tape accommodating multiple components to a predetermined supply position, and separates the cover tape from the carrier tape in front of the supply position to expose a component on the carrier tape. The tape feeder includes a pair of rotating members configured to separate the cover tape from the carrier tape by pinching and drawing the cover tape; a drum member configured to rotate and wind the cover tape drawn by the pair of rotating members; a driving motor; and a distribution mechanism configured to distribute a rotational driving force from the driving motor to one rotating member of the pair of rotating members and the drum member.
