Abstract (en)
it is provided a device for detecting introduction of foreign bodies into environments (9) of varying conformation, in particular automatic banknote dispensers (2), comprising a plurality of signal emitters (11) and a plurality of signal sensors (12), in particular infrared radiations, all disposed substantially randomly in the environment (9) to be checked, activating elements (16) capable of sequentially activating the emitters (11), a memory (18) for a data base including the sensor (12) responses on sequential activation of the emitters (11), and comparator circuits (19) adapted to detect variations in said responses relative to the data base. <IMAGE>
