A tag has a supply gear 4 rotatably installed at a side of a fastener supply guide slot by forming a supporting shaft 3, an insertion hole 3' and a supporting plate 3''. Further, an arcuate sliding recess 5 is formed at a side of the supporting plate 3'' and along the circumference of the gear 4. A movable piece 6 which is elastically connected to a ratchet 8 is movably placed in the arcuate recess 5, and is connected to an actuation bar 7. The ratchet is made to reliably contact with the gear 4, and a stopper 11 is elastically installed on the upper portion of the gear 4, while an unlocking bar 11 which is provided with cam surfaces 14 and 14' on the opposite ends thereof is inserted into a slot 5'. The actuation bar 7 is actuated in synchronization with the tag attaching operations, so that the alternate arcuate movements of the movable piece 6 make the ratchet drive the gear in an accurate manner in supplying the fasteners.
