Abstract
A tape cartridge is detachably installed in a tape printing apparatus on a cartridge installation portion that has a platen driving shaft. The tape cartridge includes a platen roller in which the platen driving shaft is inserted, an outer peripheral surface which is provided parallel with a cartridge installing direction and on an outer shell of the tape cartridge, a pair of projections formed on opposite sides of the outer peripheral surface, and a recessed portion provided on the outer peripheral surface. When seen from the attaching direction of the tape cartridge, the recessed portion is disposed on an opposite side with respect to the platen roller over an imaginary line connecting the pair of projections and disposed at a position to which one of the pair of projections farther from the platen roller is closer than the other of the pair of projections.
