Abstract
A tape cassette which contains a roll of a magnetically affixable printing tape formed around a holding reel and a roll of an ink ribbon formed around a holding reel and having a non-magnetic ink layer formed on the ribbon is set in a cassette accommodating section of a tape printer. The printing tape and the ink ribbon are fed out from their holding reels within the cassette across a cut in the tape cassette and through between a thermal head and a platen roller while being pressed by those elements to thereby perform printing. The printing tape comprises a printing layer and a magnetic layer pasted to the printing layer. S and N poles which extend lengthwise of the tape are alternately arranged widthwise on the magnetic layer. Thus, two overlapping poles of any two adjacent turns of the tape have the same polarity at any peripheral position. Thus, a relatively small force is required to draw the printing tape out from the tape cassette, and stabilized conveyance of the tape and satisfactory printing are achieved.
