Abstract: An apparatus configured to discriminate the genuineness of a certified paper by exposing the paper to a light source and transporting the paper through an environment of an alternating-current electromagnetic field. Light detectors detect the light reflected from the paper and the light emitted by a fluorescent ink on the paper and output a waveform corresponding to the intensity of the detected light, reflected light, and the detected emitted light as the paper is scanned. The resulting waveforms are used to discriminate the genuineness of the paper. The fluorescent light and reflected light can be optically split and directed to separate detecting devices. Furthermore, the alternating-current electromagnetic field can be controlled by a voltage controller and configured to be driven only when the sensor detects light from the fluorescent ink.

Abstract: An apparatus for discriminating the genuineness of a security mark is provided having a first light detecting element for detecting a light emitted from a luminescent ink of the security mark placed in a specified environment and a second light detecting element for detecting a reflected light from a non-luminescent ink of the security mark. The first and second light detecting elements detect the light from the same location of a bank note. A third light detecting element detects the light intensity of a light emitted from a monitor mark that can be compared with a preset reference light intensity to calculate a deviation from the reference light intensity. The output of the first light detecting element can be converted into a corrected output value corresponding to the calculated deviation. The genuineness of the bank note can be discriminated based on the corrected output value.

Abstract: A door unit for selectively opening and closing an opening in an object includes a door having a bendable slatted door body and a flexible sheet member positioned over the door body. Guide grooves in the object slidably guide at least the door body, and the respective ends of the door body and the sheet member are connected on one end in the sliding direction. By setting an appropriate spacing between the guide grooves, the generation of noise that would otherwise be caused by the door body and the sheet member rubbing against each other when they are opened or closed, is avoided. The use of the separate sheet member also significantly increases the options for the material to be employed for the design surface of the door unit.

Abstract: An image forming apparatus employs an image carrier (photoreceptor) cartridge having protective covers of which surface is coated with conductive shield in order to prevent frictional charging that will bring on sparking between a photoreceptor and covers. Further, the photoreceptor cartridge is equipped on its surface with an elastic member which is a foam body having a plurality of foam cells for catching foreign matter such as paper particles in order to prevent the foreign matter from damaging the surface of the photoreceptor. Moreover, the photoreceptor cartridge is also equipped with a flick member for flicking off toner deposited on a conductive brush in order to prevent the brush from becoming dirty. Owing to the above-mentioned construction, the image forming apparatus can avoid degradation in image quality.

Abstract: This invention relates to an image reader capable of reading document images in parallel with the measurement of the state of curvature of the document surface, and correcting image distortion caused by said curvature in real time. An illumination light source for reading documents is provided with a filter to separate infrared light and visible light. The visible light is used to read document image information, and the infrared light is used to measure the state of curvature of the document. Since document reading and document curvature measurement are accomplished using light having different characteristics, these operations can be accomplished simultaneously.

A memory stores the height distribution of the document, and a update device updates the height distribution of the document stored in the memory when the abnormalities do not occur in the height distribution of the document. A correcting device corrects distortion of the image data caused by the height of the document in accordance with the height distribution of the document stored in the memory.
