ABSTRACT:
In a tape reel locking and releasing device for a tape cassette having a reel locking member which is slidable between a locking position and releasing position and is urged resiliently by a torsion spring toward the locking position, a cavity is formed in the slidable locking member to receive a release pin of a tape player which is inserted into the cavity through an aperture formed in a bottom wall of the cassette case, and a projection extends downwardly from the reel locking member into the aperture and is contiguous to the cavity. An inclined plane is formed in the cavity and extends therefrom to the lower end of the projection with the release member being brought into initial pressed contact with the lower end of the inclined plane on the projection. The inclined plane can be lengthened without the necessity of extending its upper end and or increasing the gradient of the inclined plane to consequently ensure a sufficient shift length of the slidable locking member, hence achieving exact locking and releasing operations.
