A tape cassette loaded with respect to a recording and/or reproducing apparatus having a reel driving mechanism including at least one reel driving shaft, comprises a cassette case, a supply side reel and a take-up side reel provided within the cassette case, for winding a tape, and a positioning part for positioning the cassette case. One reel of said supply side and take-up side reels is constructed so that the reel driving shaft of the recording and/or reproducing apparatus is inserted into this one reel from a lower direction thereof to engage therewith when the tape cassette is loaded into the recording and/or reproducing apparatus, and driven at a center part of this one reel. The other reel of the supply side and take-up side reels is constructed so as to be rotated by a rotation transmitting mechanism at a part other than a center part thereof. The positioning part has an engaging part for positioning provided on the bottom surface of the cassette case at a position corresponding to the center of rotation of the other reel. |
