摘要

Improved videocassette, equipped with laminar springs of rationalized action and assembly, of the type constituted by a box formed by a bottom or base and by a complementary cover, inside which are located two spools carrying the tape, among which arranged a locking mechanism thereof, which for this purpose have a peripheral toothing in each of the plates, usually lower, whose teeth are introduced the free ends of separate triggers formed by double-bent arms and able to rotate, pivoting on the fixed shaft that supports them, when the inner ends of the arms of the triggers are actuated by a tilting lever, which integrates the block device which, in turn, is automatically activated when the videocassette is placed in the recording device and/or reproducer, characterized by the fact that, in order to keep the aforementioned triggers in a position of blocking and immobility of the reels, put a unitary laminar spring, of simultaneous action on the elbow arms of the triggers, whose spring has the shape of a moth with a flat rectangular base, which can be housed by simple introduction between two guide and positioning tabs, which emerge from the inner side of the raised wall delimiting the bottom base side of the videocassette, from whose rectangular laminar base and separated therefrom by respective notches there extend two symmetrical fins, which form a divergent angle and which at their free ends have respective supporting edges, which correspond and apply against the respective elbow arms of the triggers, keeping them in the locked position, whose fins of the leaf spring only experience a flexion when receiving the corresponding arms of the triggers the impulse of the release lever that makes them swing over their respective axes of rotation, causing the unlocking of the reels by the replieg that they experience the free ends of the triggers, which are reintegrated to their initial position by the reaction of the leaf spring fins, when the antagonistic action of the release lever automatically stops when the videocassette is removed from the recording and/or reproducing apparatus. That establishes and maintains said action. (Machine-translation by Google Translate, not legally binding)
