To perform feeding of a carrying tape and winding of a top tape stripped from the carrying tape at a high speed.

The tape feeder unit comprises a unit 13 for feeding a feed tape 1 produced by pasting a top tape 3 to a carrying tape 2, a claw 30 for stripping the top tape 3, a unit 14 for winding the stripped top tape 3, a drive unit 12 common to both units, and a feeding side interlocked link mechanism 28 and a winding side interlocked link mechanism 31 provided for the drive unit 12, the feeding unit 13 and the winding unit 14. Oscillatory link of the interlocked link mechanism 28, 31 is fixed with clutch gears 38, 38', 63, 63' incorporating a pair of unidirectional clutches of the same directivity as the interlocked link mechanism 28, 31 so that a rotational torque is transmitted to each unit 13, 14 through a unidirectional clutch under locked state in both first and second half driving cycles of the drive unit 12.
