A banknote acceptor is disclosed to have a banknote verification assembly detachably mounted in a housing for verifying the authenticity of the inserted banknote by means of an optical transmitter module, which uses an UV LED to emit UV light through the inserted banknote, and an optical receiver module, which uses a phototransistor to receive light passed from the UV LED through the banknote and to produce a corresponding output signal indicative of the fluorescent reaction of the fluorescent characteristics of fluorescent filaments of the paper material or the fluorescent reaction of the ink of the inserted banknote for enabling a control unit to verify the authenticity of the inserted banknote and for enabling a banknote holding down mechanism to force the verified banknote into a money box and hold it in place.
