Abstract
A desensitizer apparatus for desensitizing a security sensor element in a book spine. The apparatus includes a scanner which scans along a surface against which book spines are positioned and which detects sensor elements 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.
