Abstract: To detect a fluorescent light and a phosphorescent light emitted from a paper sheet with a high precision, a fluorescence and phosphorescence detecting apparatus includes two sensor units. Each sensor unit includes a light source that emits an ultraviolet light on the paper sheet, an image sensor that captures images of the fluorescent light and the phosphorescent light excited on the paper sheet by irradiation of the ultraviolet light, and a light receiving lens that guides the fluorescent light and the phosphorescent light excited on the paper sheet to the image sensor. The two sensor units are arranged above and below the transport path and opposing each other across the transport path, and the light receiving lenses and the image sensors in the two sensor units are off-set along a transport direction of the paper sheet.

Abstract: A paper sheet recognition apparatus can generate a subtracted reflective light image without increasing detection time. To that end, the operations of sensors are controlled in a plurality of phases. The phases include a phase (reflected infrared light 1) in which a first light emission unit emits light, a second light emission unit emits no light, and an optical sensor detects reflective light. In another phase, (reflected infrared light 2) the first light emission unit emits no light, the second light emission unit emits light, and the optical sensor detects reflective light. In at least one of these phases, a light emission unit emits light, and an optical sensor detects transmissive light.

Abstract: Light is emitted on one side of a paper sheet 100, which is being transported on a transport path, from a first light source 11, and light is emitted on other side of the paper sheet 100 from a second light source 21 and a fourth light source 22. A first light receiving sensor 14 receives a first reflected light, which is the light emitted by the first light source 11 and reflected from the one side of the paper sheet 100. A second light receiving sensor 24 receives a second reflected light, which is the light emitted by the second light source 21 and the fourth light source 22 and reflected from the other side of the paper sheet 100, and receives a transmitted light that is the light emitted by the first light source 11 and that has passed through the paper sheet 100. With this, satisfactory reflection image and transmission image of the paper sheet can be acquired while realizing the downsizing of the device.

Abstract: A banknote is irradiated with lights of plural wavelengths. Images of the banknote for each wavelength are acquired. An IR ratio image having a pixel value that is a ratio of a pixel value of the image acquired by the visible light to a corresponding pixel value of the image acquired by the infrared light is generated. The banknote image and the IR ratio image are corrected by a coefficient corresponding to the banknote type, the banknote orientation, and the wavelength. From the banknote image or the IR ratio image, by using the information pertaining to the banknote type, the banknote orientation, and the wavelength, intermediate evaluation values are calculated for each wavelength. Mahalanobis distance is calculated based on the intermediate evaluation values, an average value and a variance-covariance matrix of the intermediate evaluation values, and a degree of soiling is determined based on the Mahalanobis distance.

Abstract: A reflective member is disposed on the optical path from the linear light source to the lens array. An ultraviolet light blocking filter is provided closer to a light-receiving unit than the reflective member. A color filter is provided closer to the light-receiving unit than the ultraviolet light blocking filter. A light-receiving surface of the light-receiving unit has a first region opposed to the reflective member without the ultraviolet light blocking filter and the color filter interposed therebetween, a second region opposed to the reflective member and the ultraviolet light blocking filter without the color filter interposed therebetween, and a third region opposed to the reflective member, the ultraviolet light blocking filter, and the color filter.

Abstract: By overlapping lighting timings of light sources that emit lights of a plurality of different wavelength bands including a wavelength band of at least a visible light region and an infrared light region, the lights of the plurality of the different wavelength bands including the wavelength band of at least the visible light region and the infrared light region are emitted on a banknote while securing an overlap in timings thereof. Moreover, by using light receiving elements each including a bandpass filter that allows only light of a wavelength range that corresponds to the wavelength band of each of the light sources, received light intensities of the light of the wavelength range that corresponds to the wavelength band of each of the light sources are acquired simultaneously, and image data are formed based on the received light intensity of every acquired wavelength band.
