Patent number: 7621440Abstract: The type and number of denomination of notes and the identification method of authentic notes differs for every country. The development of such identification device for these currencies in each country increases the manufacturing cost, and the processing time increases when the types of notes to be authenticated are increased. The present invention provides a paper sheet identifier device, which includes a main board for operating common processes independent from specific notes and sub-boards in parallel operation, allowing sub-boards connected to the main board to be added or replaced in accordance with the type and number of denomination of notes in a country along with the authentication method. The present invention improves the processing speed by parallelizing the identification processes, and the efficiency of updating the device specification when a new note is issued.Type: GrantFiled: August 19, 2004Date of Patent: November 24, 2009Assignees: Hitachi Asahi Electronics Co., Ltd., Hitachi-Omron Terminal Solutions Corp.Inventors: Toshiaki Nakamura, Toshiro Uemura, Eiji Mizuno, Tatsuhiko Kagehiro, Masaki Ban

Publication number: 20090166150Abstract: 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.Type: ApplicationFiled: November 4, 2008Publication date: July 2, 2009Applicant: HITACHI,LTD.Inventors: Akira MORI, Mitsunari Kanou, Toshiro Uemura, Kenji Okuna, Noriaki Fujimura

Patent number: 7167247Abstract: The technique of the present invention enhances the stability of paper material identification of sheets. To achieve the above purpose, both short-wavelength light in the range of 370 nm and long-wavelength light in the range of 420 to 1000 nm are irradiated to paper to be identified in identifying the paper material. The identification is carried out, based on the difference in absorbance of the paper, which is obtained for each irradiated light. The absorbance of the paper varies according to the paper material, thereby enabling the identification of the paper material free from influence, which are caused by differences in manufacturing process, such as shading patterns. In addition, the simultaneous use of the short-wavelength light and the long-wavelength light declines influence on the absorbance, which are caused by environmental factors, such as humidity and deterioration of sheets, thereby resulting in stable identification of the paper material.Type: GrantFiled: April 17, 2003Date of Patent: January 23, 2007Assignee: Hitachi, Ltd.Inventors: Toshiro Uemura, Yoshitaka Takezawa, Mitsunari Kano, Eiji Mizuno, Toshiaki Nakamura

Publication number: 20040260650Abstract: An object of the present invention is to trace a user who has deposited bills as counterfeit bank notes into an ATM. The ATM having a bill deposit function judges a denomination and genuineness of bills deposited by the user by a validator, extracts bill information and stores in a search DB its bill information to be matched with an account number of the user (first data). It stores, in a trace DB, bill information of bills judged as counterfeit bank notes by the validator (second data). The search DB is searched with the second data as a key to extract similar bill data for specifying, from a result, the user who has used the bills as counterfeit bank notes.Type: ApplicationFiled: June 10, 2004Publication date: December 23, 2004Inventors: Yuji Nagaya, Toshiro Uemura, Tatsuhiko Kagehiro, Hiroshi Sako

Publication number: 20030057053Abstract: The present invention relates to a technique of improving an apparatus for sheets discrimination with accuracy. Ultraviolet rays are illuminated to a sheet, such as banknote, and a light-receiving sensor 4 and 5 receive fluorescence emitted by a sheet using the light reflected from a sheet and ultraviolet rays as an excitation light. Moreover, the light-receiving sensor 5 receives the diffused and reflected light irradiated to a reflector 1 installed under a sheet conveyor 17. Correcting the reflective light and fluorescence detected based on strength of the irradiating light in the state without a banknote enables the discrimination with a high degree of accuracy even if an error is included in the irradiating light caused by the problems such as an aging of illuminant.Type: ApplicationFiled: August 23, 2002Publication date: March 27, 2003Inventors: Mitsunari Kano, Toshiro Uemura, Eiji Mizuno
