ABSTRACT:
An apparatus, such as a cassette or a cartridge, for storing a continuous tape medium in reeled form has first and second hubs contained in a housing having a base, with a continuous tape medium wound on said hubs, with a portion of the tape medium wound on one hub and another portion wound on the other hub. The hubs are respectively mounted on axles allowing rotation of the hubs. The axles are rotatably mounted in a platform which is slideable within an opening in the base of the housing so as to allow the axles to exhibit a translational movement, in tandem, in a direction parallel to the base as the tape medium is transferred between the hubs. As the diameter of reeled tape increases on one of the hubs due to the tape transfer, the platform, and the axles and the hubs, will move in a direction toward the housing sidewall closest to the hub having the smaller amount of tape reeled thereon, thereby increasing the spacing between the other hub and the other sidewall to accommodate the increasing diameter. The movable mounting of the axles and hubs allows significantly more length of tape to be contained in the housing, reeled on the hubs since a larger diameter tape reel can be accommodated when all of the tape is fully wound onto one of the hubs.
