Claims (8)

1. The banknote acceptor contains: the housing (1) contains the front panel that defines the banknote machine (111) for inserting the banknote (4); device for accepting banknotes (2) which is located in the said housing (1), said device for accepting banknotes (2) contains a holder base (21) that defines the passage of banknotes (20) in communication with the said machine for banknotes (111), control module (22), a transfer mechanism (23) which controls said control module (22) for transferring the inserted banknote (4) and circular recognition assembly (24) mounted on the opposite top and bottom side of said banknote passageway (20), said circular the recognition assembly (24) contains a sampling and validation module (240), contains a plurality of light emitters (241) and light sensors (242) and is controlled by said control module (22) for validating the authenticity and nominal value of the banknote (4); and at least one privacy filter (3) mounted in the light path of said bill acceptor (2) between said bill passage (20) and said light sensors (242) for filtering external light sources and for releasing light emitted by said light emitters (241) passage to light sensors (242), characterized in that the privacy filter (3) is a multi-layer filter that is made using blind ultra-fine (micro-louver) optical technology, where the privacy filter (3) reduces the angle of the light path when passing through banknote (20), enabling the light to be emitted only through the light emitters (241) to pass through the banknote acceptor (20) at an angle of 90° or 600 ±5°. 2. Banknote acceptor as stated in claim 1, where said base holder (21) of said banknote acceptance device (2) contains at least one light transmission part (213) available around said banknote acceptor (20) corresponding to said a circular recognition assembly (24) and a privacy filter (3) and a locating funnel located around each said light transmission portion (213) for supplying at least one of said privacy filters (3). 3. A banknote acceptor as set forth in claim 2, wherein each said privacy filter locating chute (2231) contains two said privacy filters (3) in the device. 4. A bill acceptor as set forth in claim 2, wherein said base holder (21) of said bill acceptor (2) further comprises a protective cover (214) mounted on each chute of said privacy filter (2231) to hold at least one filter (3) in each funnel of said privacy filter (2231 ). 5. A banknote acceptor as set forth in claim 1, wherein said control module (22) of said banknote acceptance device (2) comprises two circular plates (221) which are individually mounted on said base holder (21) on opposite top and bottom sides said banknote passage (20) and a plurality of sensors (222) which are installed on said circuit boards (221) and adapted to sense the insertion of a banknote (4) into said banknote machine (111); said light emitters (241) and light sensors (242) of said sampling and validation module (240) said circular recognition assembly (24) which are individually installed two circular plates (221) of said control module (22) of said acceptance device banknote (2) . 6. A banknote acceptor as set forth in claim 5, wherein said sampling and validation module (240) further comprises a plurality of lens carriers (243) individually mounted around said light emitters (241) and said light sensors (242), each said IEEE holder (243) contains a hole (2430) intended for one said light sensor (242) and a lens set is mounted in said hole (2430). 7. Banknote acceptor as stated in claim 1, where said base holder (21) and said banknote acceptance device (2) contain at least one light transmission part (213) which is located around said banknote passage (20) corresponding to said a circular recognition assembly (24), said groove for locating a privacy filter (2231) located around each said light transmission part (213), a protective cover (214) mounted on each groove of said privacy filter (2231) to hold at least one said privacy filter (3) in said at least one light transmission part (213); said control module (22) of said banknote acceptance device (2) contains two circular plates (221) which are individually mounted on said base holder (21) on the opposite top and bottom sides of said banknote passage (20), a number of sensors which are installed on the said circular plates (221) and adapted to sense the insertion of a banknote (4) into the said banknote machine (111) and the tray (223) mounted on each circular plate (221) via the sensor of the corresponding circular plate (221), where the said tray ( 223) contains a funnel for the location of the privacy filter (2231). 8. The banknote acceptor as stated in claim 1, where said bed (223) contains at least one hole (2230) which is available on said said chute for locating privacy filters (2231) corresponding to sensors; where said privacy filter locating chute (2231) is available for at least one privacy filter (3) and a plurality of protrusions (2232) located on the privacy filter chute (2231) holding at least one privacy filter (3 ) and specified privacy filter sink (2231).
