DEVICE FOR CHECKING AUTHENTICITY OF SECURITIES AND/OR DOCUMENTS Russian patent published in 2007 - IPC G07D7/12 G06K9/00 

FIELD: technology for visually checking securities and/or documents, protected from falsification, possible use, in particular, for creating a highly productive device meant for realizing complex control of both visual and machine-readable protection signs of securities and/or documents.

SUBSTANCE: device contains spatial orientation block for test emitters in form of two conical cases with through radial apertures positioned along a circle, in which apertures primarily light diode emitters of test radiation are positioned, while conical cases are held in the body of the device between objective of receiver and viewing window, their central axes being combined with optical axis of receiver objective, while through radial apertures with test radiation emitters positioned thereon are inclined towards optical axis of receiver objective towards the viewing window, while the angle of inclination of through radial apertures with test radiation emitters of conical case closest to input aperture of receiver objective is less than analogical angle of inclination of through radial apertures with test radiation emitters of another conical case. Test emitter spatial orientation block is equipped with test radiation disperser in form of conical ring, held on internal surface of conical case closest to the receiver objective. Laser emitter is mounted in the device, with its emission oriented towards the viewing window, while the receiver of test radiations is equipped with a set of replaceable light filters, each one of which has a transmission band corresponding to one of the bands of reemitted light radiation being controlled, for example in form of rotary disk with ports, where light filters are held, mounted oppositely to receiver's objective.

EFFECT: increased productivity of labor, decreased costs of operations involving authenticity checks of securities and/or documents.
