Abstract:
A paper-sheet-thickness detecting sensor of the present invention includes: an oscillator that outputs high-frequency signals with frequencies corresponding to positions in a horizontal direction that is orthogonal to a direction in which a paper sheet is transported; a signal electrode to which the high-frequency signals output by the oscillator are applied; a plurality of detection electrodes that face the signal electrode across a transportation path for the paper sheet and that individually detect detection signals that correspond to the positions; a plurality of resonance circuits that each have one end connected to one end of each of the plurality of detection electrodes and that have resonance frequencies equal to the frequencies allocated to the positions; and a broadband amplifier to which another end of each of the plurality of resonance circuits is connected and that outputs outputs of the plurality of resonance circuits as one piece of sensor output information.
Abstract:
The present invention relates to an ultrasonic sensor for detecting double sheets and a method of detecting double sheets using the same, in which in configuring the ultrasonic sensor for detecting double sheets of banknotes passing through a transfer path, the ultrasonic sensor is configured to include an ultrasonic wave generator and an ultrasonic wave receiver provided in pair to face each other in a direction perpendicular to a transfer direction of the banknotes with the transfer path for transferring the banknotes interposed therebetween, and periodicity of a reception signal detected by the ultrasonic wave receiver is determined to detect whether a zero sheet, a single sheet or double sheets of the banknotes pass through the transfer path according to generation or not of the periodic signal and/or a frequency of the generation.
Abstract:
A method and a device for automatically diagnosing a sorter fault are provided. The method includes: obtaining a banknote image of a banknote by scanning; performing data processing on the banknote image based on a preset detection algorithm, to obtain a processing result; and sending a feedback information if the processing result satisfies a preset condition.
Abstract:
According to one embodiment, an image reading apparatus that reads an image of a sheet conveyed by a conveyance unit includes a first illumination unit to irradiate the sheet with visible light, a second illumination unit to irradiate the sheet with visible light and infrared light from an angle different from that of the first illumination unit, and an imaging unit to receive visible light and infrared light reflected from the sheet and to capture a visible image and an infrared image.
Abstract:
An apparatus is disclosed. The apparatus includes a document processor and electronics connected to the document processor. The electronics includes a document sensor system and means for determining a document processing situation of a plurality of document processing situations. The document sensor system is connected to the means. The plurality of document processing situations include a single document situation and a double document situation. The double document situation includes a partially-overlapped, double document situation and a completely overlapped, double document situation. A method is also disclosed.
Abstract:
A document handling apparatus is disclosed which is particularly well adapted for counting documents of value, such as banknotes. The document handling apparatus comprises an input module for receiving a stack of documents and feeding them one by one into the apparatus, a detector box which houses a series of detectors for detecting characteristics of the documents, a transport system for conveying documents within the apparatus, a doubles detector for sensing the passage of each document therethrough and a stacker module for stacking the output documents and presenting them to the user. The apparatus is based on a metal framework in a plastics housing.
Abstract:
A paper sheet processing apparatus capable of preventing conveyance failure of a paper sheet. The apparatus includes a bill insertion slot, a bill conveyance mechanism capable of conveying a bill inserted from the bill insertion slot, a bill reader reading the bill conveyed by the bill conveyance mechanism, an authenticity determination mechanism determining the authentication of the bill read by the bill reader, a bill determination processing part for determining, before the reading of the banknote by the banknote reader is completed, damage to the bill based on a shape of a portion of the bill which is read and on a shape of a reference bill, and a controller controlling conveyance of the bill by the bill conveyance mechanism based on a result of the determination by the bill determination processing part.
Abstract:
A technology that increases bill discrimination precision, wherein a bill discriminating apparatus detects the thickness distribution of a bill P that is subject to discrimination, and by comparing this thickness distribution data and the reference thickness distribution data that shows the thickness distribution of an authentic note held in advance, performs discrimination processing that includes double feed detection, tape detection, and authenticity discrimination. Then, authenticity discrimination is performed on areas for which the difference between the thickness distribution data and the reference thickness data is within a specified range.

Abstract:
When a thickness sensor detects a corner fold in a front end part of the paper sheet being carried, a light sensor checks whether a break exists or not in the front end part. When there is no break, it means the thickness sensor does not detect a corner fold but a foreign matter such as a tape mending a break. When there is a break, it means the thickness sensor detects a corner fold in the front end part. When there is no corner fold, the light sensor checks the front end part. When there is a break, it means there is a corner break but no corner fold in the front end part. When there is no break, it is a normal state. Regarding the back end part, a corner fold is detected in similarly to the foregoing.
