特徴とするテープカートリッジ。A tape cartridge having a drive shaft insertion hole 2 in a main body case 1 into which a deck-side drive shaft 5 is inserted, and a hub 4 on which a tape is wound inside the main body case 1 is rotatably supported on the drive shaft insertion hole 2. , upper and lower inner wall surfaces 11 of the main body case 1,
11 and the hub 4, elastic members 12a and 12b for pressing and biasing the hub 4 in the axial direction are arranged vertically opposite each other, and each elastic member 12a and 12b is expanded and deformed in the radial direction. The drive shaft 5 is formed into a possible ring shape.
has a passive part 14 that comes into contact with the outer periphery of the elastic member 12b, and when loading onto a deck, the drive shaft 5 comes into contact with the passive part 14 of one elastic member 12b located on the insertion side of the drive shaft 5, and By expanding and deforming the member 12b in the radial direction, the axial pressing force of the elastic member 12b is released or weakened, and the axial reference end surface a of the hub 4 is moved to the drive shaft 5 by the pressing force of the other elastic member 12a. A tape cartridge characterized in that a reference receiving surface A is pressed and biased.
