Abstract
In a single-reel type tape cartridge, a coupling portion of a leader tape includes a pair of winding pieces disposed at opposite sides of a cutout and each winding piece includes a base portion and a turnover portion wound around a pin of a leader member so as to be ultrasonically welded to the base portion. An anvil for supporting the coupling portion of the leader tape has a pair of anvil faces each having a width smaller than that of the turnover portion and ultrasonic welding of the turnover portion to the base portion is performed by supporting the coupling portion on the anvil faces. The turnover portion is divided into a completely welded area having a width substantially equal to that of each of the anvil faces and an incompletely welded area disposed outside each of opposite side edges of the completely welded area.
