Abstract

Film or tape cassette has a housing, lid and hub forming a unit to centre the spool, with a lock with a deformable member and a rotatable operating cam. The deformable member has at least three flexible lamellae, pref. of formaldehyde resin, extending parallel to the rotation axis of the cam, which is mounted in a hut. The foot of each lamella is arrested in this first hub; the free outer end of each lamella rests, against the cam and forms an outward stand over tooth. The second hub bounds the central opening, which is bordered by a convergent seating towards the first hub. The tooth can be pressed by the cam against the seating to cause the lid to lock with the housing and to move these two aprts together, so that a pressure is exerted on the reel.
