  • Patent number: 10789802
    Abstract: A paper sheet processing device includes: a charging inlet that takes in paper sheets in a conveyance direction, the paper sheets including at least one target sheet and a partition card overlapped on the target sheet, the partition card having a main surface portion having at least one identification hole group, the identification hole group having at least two through holes arranged along the conveyance direction; a detection unit that detects take-in of the paper sheets by the charging unit, and detects the identification hole group; and a control unit that determines a paper sheet is the partition card in a case where the identification hole group has been detected by the detection unit, and determines that a paper sheet is the target sheet in a case where the identification hole group has not been detected by the detection unit.

  • Patent number: 7440604
    Abstract: An image detector for bank notes is provided which can be made at low cost and in small size. The image detector comprises a pair of detector units 13 includes a first image detection sensor 24 which detects an image of a first detection area mounted on one side of a detector unit 18, a first light emitting device 27 which irradiates light towards the first detection area, and a second light emitting device 31 which irradiates light towards a second detection area mounted on one side of the unit main body 18 but in a different location from the first detection area, a pair of detector units is disposed so as to oppose one another across a bank note transportation path 12, in a manner which enables the image detection sensor 24 of one of the detection units 13 to detect an image of the second detection area of the other of the detection units 13.

  • Patent number: 5887697
    Abstract: A coin discriminating apparatus includes a plurality of light emitting elements for projecting light onto a coin, a light receiver for optically detecting light reflected by the coin, and a scattering member, disposed on an opposite side of the coin from a light receiver, for scattering light emitted from the plurality of light emitting elements. The light receiver receives light reflected by the coin and light scattered by the scattering member and produces pattern data. The coin discriminating apparatus further includes a coin discriminator for detecting a diameter of the coin based on the pattern data produced by the light receiver, tentatively determining a denomination of the coin, and comparing the pattern data of the coin produced by the light receiver with reference pattern data of a coin of the tentatively determined denomination.

  • Patent number: 4369360
    Abstract: A number of bank notes are inserted into the bank note entrance unit of a bank note depositing apparatus and are continuously received so that they may be inspected and counted at a high speed. After the counting operation, the bank notes are stored in a temporary storage unit and subsequently in such one of the plural storage portions of a movable safe as is positioned to receive the bank notes from the temporary storage unit. Another standby vacant storage portion of the movable safe is then automatically brought to the same position to receive the bank notes when a predetermined number of the bank notes are stored in the first storage portion.
