ABSTRACT:
When different tape cartridges accommodating printing tapes having different hardness, thicknesses or widths are exchangeably mounted in the same printing apparatus, excellent printing can be obtained using the present embodiment. In a platen 12 provided in a tape cartridge 10, the harder, thicker or wider the tape T accommodated in the tape cartridge 10, the softer a platen rubber provided on a surface of the platen. The platen rubber 14 having a hardness corresponding to the properties of the tape T is used so as to obtain an ideal contact state between a printing head and the tape T regardless of the properties of the tape T when the tape cartridge 10 is mounted in a tape writer 1. Accordingly, the tape T can be properly conveyed by the platen 12 and a tape guide pin 26 regardless of its properties, and can be brought into contact with a printing head through an ink ribbon R in an ideal and consistent contact state. As a result, the printing head performs a printing operation under optimum conditions and high quality printing can be obtained.
