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.

Abstract: A tape and/or ink ribbon cartridge releasably insertable into an inserting section of a tape printer has ink ribbon supplying and recovering sections in a casing of the cartridge and an ink ribbon path extending from the ink ribbon supplying section to the ink ribbon recovery section through a printing position. The ink ribbon path has a portion defined by first and a second side walls facing with each other across a constant gap. The first side wall has an opening formed therein. A shutter portion is formed for closing the opening when the upper and lower casing parts are assembled to constitute the casing of the cartridge. One of the side walls which faces to the ink surface of the ink ribbon has a wavy surface. With the opening formed in the side wall, the ink ribbon can easily be inserted in the narrow path between the first and second walls. Since the wavy surface is formed on the side wall, the ink ribbon is prevented from sticking on the side wall.
