  • Patent number: 7942401
    Abstract: The invention provides an ATM that can stably stack paper money by preventing the rotation of stack rollers when paper money is deposited. The ATM includes feed rollers, stack rollers, and elastic members. The feed rollers convey paper money separated one-by-one by pickup rollers onto a money withdrawal path, or convey paper money conveyed along a money deposit path into a recyclebox. Peripheries of the feed rollers are formed of rubber. Each of the stack rollers includes wings. When paper money is deposited, the stack rollers come in contact with the feed rollers. Peripheries of the stack rollers are formed of synthetic resin. The elastic members push the stack rollers against the feed rollers, and apply elastic forces to the stack rollers such that a frictional force between paper money and the stack rollers is smaller than that between paper money and the feed rollers.

  • Patent number: RE43358
    Abstract: A data reading apparatus for reading and/or scanning data from a first and second scanned medium comprising a first transportation path P1, along which the first scanned medium is conveyed and a second transportation path P2, along which the second scanned medium is conveyed and wherein the first and second transportation paths each have a common mutually shared middle transportation path through which both scanned media must pass and a common data reader reading data from each scanned medium respectively. Checks S are conveyed on the first transportation path P1, cards C are conveyed on the second transportation path P2 at a different transportation height from that of the first transportation path P1 with data read from the respective media as they are being conveyed. Because the transportation heights differ, scanned media can be transported on different transportation paths without involving special switching devices.
