FIELD: protection of securities, specifically, banknotes against falsification. SUBSTANCE: proposed machine includes paper feeder, paper transporting unit and unit 19 of optical deposition of changing images located on at least one tape that is brought into contact with treated paper so that these images are superimposed on paper in areas corresponding to prints of this security determined in advance. Unit 19 of optical deposition of changing images has at least one cylinder-applicator 11 interacting with pressing roller 20 between which treated paper passes. Tape with images is mounted between two coils arranged in sector of cylinder-applicator 11. Thus tape passes along element of above-mentioned cylinder- applicator perpendicular to trajectory of movement of treated paper under action of servomotor operating under intermittent mode in each step of image superimposition. EFFECT: enhanced reliability and operational stability of machine. 10 cl, 7 dwg
