Abstract

A tape cassette is loaded with respect to a recording and/or reproducing apparatus having a reel driving mechanism including at least one reel driving shaft, where the tape cassette comprises a cassette case, a reel provided within the cassette case, for winding a tape, and a reel displacement limiting mechanism for limiting displacement of the reel. The reel displacement limiting mechanism comprises a first teeth part having crests and valleys, formed on the lower surface of the reel, a second teeth part having crests and valleys, formed on a bottom plate of the cassette case at a position opposing the first teeth part of the reel, an urging mechanism for urging the reel toward the bottom plate of the cassette case so that the first and second teeth parts mesh with each other, and a displacement limiting mechanism for limiting displacement of the reel along a radial direction thereof in a state where the first and second teeth parts are meshed to a quantity smaller than a displacement quantity of the reel along the radial direction thereof in a state where the reel is lifted against the urging force of the urging mechanism and the mesh between the first and second teeth parts is released.
