Abstract: A locking/unlocking means for cassettes, in particular those having swivel cover flaps, consists partially or completely of elastically deformable material and is pivotably mounted at two or more points. In the rest position of the locking/unlocking means, advantageously a swivel plate, an essentially tension-free arrangement is obtained by means of a supporting extension above the bearing axis, by actuation from outside, the said arrangement being converted in the operating state, without further spring elements, into a state of tension and into a position in which the supporting extension rests against the inside of an outer cassette wall and a reaction force corresponding to the actuating force is generated without any additional spring. Such a locking/unlocking means is suitable for cassettes of all types.
