<p>A tape cassette for use in a magnetic recording/reproducing apparatus comprises a housing having top and bottom plates with a pair of tape reels rotatably accommodated side-by-side in the housing between the said plates, and a locking means comprising a plurality of recesses formed on the outside peripheral surface of one flange of each tape reel and at least one locking lever having a pair of brake members extending mutually away from one another across the respective peripheral edges of the tape reel flanges. The locking lever(s) are pivoted with respect to the housing and are resiliently biased for rotation in such a direction that the brake members are brought towards the respective tape reel flanges into locking engagement with respective recesses of the reels when the cassette is not in its position of use. The cassette housing has an aperture for a release pin which, upon insertion of the cassette into its position of use in the apparatus, is operative to rotate the lever(s) in opposition to the resilient bias to disengage the brake members from the tape reels.</p> |
