  • Patent number: 7309019
    Abstract: A method of checking a sheet as to forgery thereof, the sheet being provided with an electronic circuit chip from or in which information can be read out or written and having visible information. The method includes a step of encrypting the visible information of the sheet and storing the encrypted visible information in the electronic circuit chip, and a step of determining discriminatively the authenticity of the sheet by comparing the visible information of the sheet with the information stored in the electronic circuit chip.

  • Publication number: 20040156176
    Abstract: In a method of mounting a planar electronic circuit chip onto a flexible sheet together with another planar electronic element, the electronic circuit part and the another electric element are selected so that the planar surface of the another electric element is greater than the planar surface of the electronic circuit chip, and the another electric element and the electronic circuit chip are mounted on the sheet so that the planar surface of the another electric element and the planar surface of the electronic circuit chip are in parallel with the sheet surface, and the planer surface of the electronic circuit chip is accommodated within the planar surface of the another electric element as viewed in a direction perpendicular to the sheet surface.

  • Patent number: 5626821
    Abstract: A cash transaction machine performs receiving and/or paying transactions of bills by manipulation of a user, transfers bills between a receptacle where bills are paid in and out and a storage where bills are stored, and by using a sterilizing unit for heat-sterilizing bills being transferred at a specified temperature range and a specified time period.

  • Patent number: 5563394
    Abstract: Cash transaction machine and method for receiving and/or dispensing money by user's manipulation to transact the money comprise a bill receptacle, a bill dispense port, a bill storage and a transport unit for transporting the bill between the receptacle and/or the dispense port, a disinfection unit, and the storage. The bills received and/or to be dispensed are disinfected by the disinfection unit arranged in the transport unit by heating the bills by a heated roller, irradiating the bills by an ultraviolet ray from an ultraviolet ray lamp or applying disinfecting liquid to the bills. Alternatively, the bills are disinfected by a disinfection unit arranged in the storage by heating the bills by a heater or irradiating an electromagnetic wave to the bills.
