ABSTRACT:
A tape cassette comprises a set of two front and back cassette halves, each half having a pair of apertures each of which is surrounded by an inward-extending annular projection and is aligned with an aperture and annular projection on the other cassette half, and a pair of tape reels, each of which has an inner surface surrounding two such aligned annular projections and comprises an annular flange which extends inward from the inner surface of each reel, which forms a step down from each side of the reel, and which is provided with means for engaging a driving shaft. The two aligned annular projections are in supporting engagement with the two sides of the annular flange, and the two sides of each reel are separated by a clearance from the two cassette halves.
