    摘要: A paper-like sheet discriminator has reference rollers for detection of a thickness of a paper-like sheet and a detection roller opposing the reference rollers. The paper-like sheet is passed between the reference rollers and the detection rollers and its thickness is detected from a displacement of the lever. Wavelength components less than a specified wavelength are extracted from a signal indicative of a thickness of the paper-like sheet passing through the respective thickness detection sensors and appearance positions on the paper-like sheet are determined at which the extracted wavelength components being less than the specified wavelength and having amplitude either not less than or less than a constant value appear. The thus determined appearance positions are collated with precedently stored appearance positions so as to discriminate genuineness/spuriousness of the paper-like sheet.

    摘要: Electromagnetic toner is supplied to the surface of the image development drum formed of a hollow aluminum covered with electric insulation; a permanent magnet is installed in the hollow portion of the image development drum; a recording electrode is provided on the surface side of the image development drum with a small gap formed between the drum surface and the electrode; a voltage is applied between the recording electrode and the image development drum according to the image to be recorded; the image development drum is turned to form a toner image on its surface; and the toner image formed on the drum surface is then transferred onto a recording sheet.

    摘要: In a discrimination apparatus of the invention, a banknote or another paper as an object of discrimination is irradiated with ultraviolet radiation from an array of multiple ultraviolet-emitting LEDs. The ultraviolet radiation passes through a visible radiation block filter and is focused onto a preset site of the banknote by a lens. Multiple photodiodes are used to measure the transmitted light of ultraviolet radiation and the fluorescence, which is excited by the ultraviolet radiation from the banknote. The discrimination apparatus of the invention discriminates counterfeit banknotes from genuine banknotes, based on the observed pattern of the transmitted light over a preset range of the banknote. The technique of the invention desirably enhances the accuracy of discrimination in the discrimination apparatus that discriminates counterfeit banknotes from genuine banknotes.
