Abstract
A tear tape changer, in which guide rollers positioned at downstream ends of two transfer paths are disposed displacedly from each other in the front and rear direction orthogonal to a tape feed direction to prevent mutual interference of tapes even when the tapes are stretched crosswise from the guide rollers toward two route changing rollers. After the tape stretched on the route changing roller which is standing by in a stand-by position has been fed to a backup roller with an approaching motion of a pressure roller to the backup roller, the route changing roller is moved to a feed position. At the same time, the route changing roller which is standing by in the feed position and which is in an empty state is moved in the rear direction by a relief means while moving it to the stand-by position. As a result, the empty route changing roller returns to the stand-by position without interference with the tape which is stretched on the other route changing roller and which is in use, thus permitting the tape to be stretched on the pressure roller.
