Abstract
A tape cartridge of the floating roller type, wherein the floating roller is supported in a highly stable manner. The floating roller has axial bearings projecting at its opposite ends, with at least one bearing having a wide flat surface that stabilizes the roller against tipping. The roller bears against tape rolls wound upon reels that have small flanges that aid in starting the tape ends on the reels, and the floating roller has a recess at the level of the flanges to enable the periphery of the roller to move substantially against the tape-supporting surface of the reel. A substantially transparent cartridge housing has slightly raised pads that support the axial bearings on the floating roller, the pads having textured surfaces that avoid noticeable marring by the floating roller bearings.
