A desensitizer apparatus (10) for desensitizing a security sensor in a book spine. The apparatus includes a scanner (12) which scans along a surface against which book spines are positioned and which detects sensor elements (28) in the spines to be sure that only one book is positioned against the surface If only one sensor element is detected, a signal is generated which operates a drive mechanism to move desensitizer magnets close to the surface to deactivate the sensor element in the book.

L'invention se rapporte à un appareil désensibilisateur (10) qui désensibilise un élément détecteur de sécurité dans un dos de livre. L'appareil comprend un dispositif de balayage (12) qui effectue un balayage le long d'une surface contre laquelle sont placés des dos de livres, et qui détecte des éléments détecteurs (28) placés dans ces dos afin de vérifier qu'un seul livre est positionné contre la surface. Si un seul élément détecteur est détecté, un signal est généré et met en action un mécanisme de commande qui déplace des aimants désensibilisateurs près de la surface afin de désactiver l'élément détecteur du livre.
