DISPOSITIF DE BLOCAGE ET DE VERROUILLAGE, EN PARTICULIER EN VUE DE LA PROTECTION DE DISQUES MAGNETIQUES SOUPLES ENFERMES DANS DES ENVELOPPES PROTECTRICES

摘要

The invention relates to a blocking and locking mechanism, in particular for the protection of flexible magnetic discs enclosed in protective jackets, the opening serving for the insertion and removal of the information carrier being closed by a plate and the said plate being set in motion by means of a stop element, fitted on the shaft of the actuating button, using a lever arm. The essential point is that the stop element is connected to the lever arm only periodically, in each case in one phase of the opening and of the closing of the device. <IMAGE>
