Abstract: 1. Banknote sorting and counting device comprising a case in which a control unit with an interactive interface designed for adjusting of sort parameters by means of monitor and keyboard, single note off pile feeding unit are arranged, a transport system for note feeding to detectors of the unit for note counting and note passing control, a banknote authenticity, the value and unfitness degree determining unit, a banknote stream splitting unit for directing the notes into one of the stacking units with vessel depending on a decision taken by the computing unit on the basis of data retrieved from detectors, stacking units with vessels for stacking counted and sorted banknotes, wherein positioning parameters of both magnetic mark detector (15) and aligning plates (6, 7) of the single note feeding unit (4), stacker wheel (90) rotation speed and adjustment of the clearance between surface of rings (36) of separating unit (8) and surface of belts of the feeding conveyor are controlled automatically with the control unit (22) depending on the size of banknotes loaded into the device, the feeding transportation assembly (10) of the unit (4) feeding notes one by one off the pile (5) has its separate drive with automatic adjustment of the feeding speed depending on the size of the banknote to be loaded into the device, a banknote pile pressing assembly (9) is introduced to ensure a stable contact between the lowest banknote in the pile and the transportation belts of the feeding assembly (10) equipped with a detector checking presence of banknotes in the pile holder and connected to the press assembly drive control, the single banknote feeding unit (4) is equipped with moving guides (6, 7) with a drive for strictly symmetrical positioning of the banknote pile in relation to longitudinal axis of the transportation mechanism regardless of the banknote size, the banknote authenticity, the value and unfitness degree determination assembly comprises scanning devices (12, 13) allowing to obtain full image of both sides of the banknote in the visible spectrum range, in the infrared spectrum range and induced image obtained during illumination in the ultraviolet spectrum range, connected to the computing unit arranged in the control unit (22) that processes data retrieved from scanning devices (12, 13) with the help of pattern recognition software that is installed on it in advance and transfers the decision on authenticity, the value and unfitness degree of the banknote to the banknote stream splitting assembly (18) in order to direct counted and sorted banknotes to one of the stacking assemblies (19, 20, 21) with vessels (94), a scanning device for retrieval of banknote images from one split light stream in the visible and infrared spectrum ranges (12) comprising illuminators for visible (71) and infrared (72) light, a lens (104), a semitransparent mirror (105), light filters for selection of the visible spectrum range (106) and the infrared spectrum range, an image reading device (109); a scanning device for retrieval of banknote images from one split light stream in the infrared spectrum range and induced image obtained during illumination in the ultraviolet spectrum range (13) comprising ultraviolet illuminators (74) and infrared illuminators (72), a semitransparent mirror (105), an optical band light filter passing the visible spectrum range (110) and a light filter for selection of the infrared 25 spectrum range (107), an image reading device (109). 2. Device as claimed in claim 1, wherein the banknote press assembly (9) with the lift mechanism drive (Fig. 1,4) comprises two cylindrical guides (45) that are fastened with holders (46) to a limiting plate (23) designed to support the front part of the banknote pile and moves along which a carriage (47) on which a press (48) made of bent polished sheet is fastened, the press having a straight section parallel to the upper part of the banknote pile, the lifting of the press prior to loading a banknote pile being executed with the lifting mechanism comprising a timing belt (49) whose one end is passed over a smooth pulley (50) and whose other end is engaged with a cog-pulley (51) fastened on the shaft (52) of electrical motor, between the cog-pulley and the smooth pulley a tie (53) is fastened, its size exceeding the slot of the hook (54) fastened on the carriage of the press over which a belt is passed. 3. Device as claimed in claim 1, wherein the separating assembly (8) of the single note feeding unit is equipped with three rings made of friction material each of which is stretched on a roller, the three rollers shaping the external contour of the separating assembly, the upper one being a drive roller, the other two creating straight line geometry of separating contact stripes, two auxiliary spring-loaded pressure rollers arranged on the sides of the separating assembly increase the contact of the lowest banknote with the belts of the feeding conveyor and stabilize the separation process. 4. Device as claimed in claim 1, wherein the feeding transportation assembly (10) (Fig. 1, 2) comprises three sections unconnected to each other - two lower transporter sections (55, 56) and one upper transporter section (57), the carriers of transporters being round endless belts made of friction material and stretched on the drive drums with grooves (58) fastened on shafts and driven drums (59) mounted on axles, the feeding transport assembly being driven with a two-sided timing belt (60) engaged with cog-pulleys (61) fastened on shafts of driving drums and a cog-pulley (62) fastened on the shaft of the drive electric motor (63). 5. Device as claimed in claim 1, wherein transportation system (11) for banknotes (Fig. 1, 2) comprises a number of sections of upper and lower transporters whose carriers are round endless belts made of friction material and stretched on the drive drums with grooves (64) fastened on shafts and driven drums (65) mounted on axles, and is designed for passing banknotes sequentially through scanning devices (12, 13) of the assembly for banknote authentication and the value and unfitness degree determination, ultraviolet detector (14), magnetic mark detector (15) and banknote passage control and counting detector (16); for continuity in the transport system in the gaps between the scanning devices (12, 13) and the magnetic mark detector (15) the passage from one section to another is done on a drum thanks to a symmetrical shift in position of a pair of drawing round belts of the next section to neighboring grooves, for synchronicity in operation of different transport system parts the driving is done with one double-sided timing belt (66) engaged with cog-pulleys (67) fastened to the shafts of section drive drums and with cog-pulley (68) of the drive electrical motor (69) featuring a rotation speed stabilization system, smooth pulleys (70) fastened to axles are designed to give belts a specified direction. 6. Device as claimed in claim 1, wherein the banknote transportation systems comprises a flat drive belt and driving cog-pulleys are replaced with flat and barrel-shaped ones for noise reduction. 7. Device as claimed in claims 1, 2, which comprises two fit banknote stacking assemblies, two unfit banknote stacking assemblies and one stacking assembly for banknotes whose authenticity and value are doubtful. 8. Device as claimed in claims 1, 2, 3, 4, which additionally comprises a banknote microprint reading scanner.
