<p>A tape cassette capable of ensuring smooth and positive traveling of a magnetic tape in a casing. Sheet elements (30) each are formed with a pair of apertures (32) aligned with hub holes (16) of a casing (10) and a strip-like projection (34) projecting toward the inner surface of the casing (10), which is formed on each of the upper and lower inner surfaces thereof with a land (44) of a width larger than the diameter of the hub hole in a manner to face the projection of the sheet element. The casing is also formed on each of the upper and lower inner surfaces thereof with a pair of recesses (46) in a manner to interpose the land therebetween and the sheet elements each have a pair of end edges (40a, 40b) extending in the longitudinal direction thereof, which are arranged so as to overhang the recesses of the casing.</p> |
