Safety device making it possible to detect the movement of a sheaf of paper with respect to its support

摘要

Safety device making it possible to detect the movement of a sheaf of paper with respect to its support. It consists in the combination, first of all, of a support 1 for stacking sheaves 2, such as a notepad, then of an immobilisation mounting 4 which operates by elastic gripping 3, and finally of a magnetic element for opening and closing alarm circuits as soon as all or part of the sheaf is extracted. It is intended to allow removal of a sheaf of leaflets or banknotes from their storage location to be signalled by application of a magnetic contact. IMAGE
