  • Patent number: 9396619
    Abstract: Disclosed herein is an apparatus for receiving cash and checks. The apparatus includes a bundle transfer unit, a semi-separation unit and a sheet-by-sheet separation. The bundle transfer unit transfers a bill bundle input into the apparatus. The bundle transfer unit is provided above and below the bill bundle and extends along a path for transferring the bill bundle. The semi-separation unit is installed behind a rear end of the bundle transfer unit. The semi-separation unit limits the number of bills to be transferred in such a way that only a preset number of bills separated from the bill bundle is allowed to pass through the semi-separation unit. The sheet-by-sheet separation unit is installed behind a rear end of the semi-separation unit. The sheet-by-sheet separation unit separates bills transferred from the semi-separation unit from each other sheet-by-sheet.

  • Patent number: 8807423
    Abstract: An automatic teller machine (ATM) may temporarily stack paper mediums in a carriage, adjust an advancing direction of the carriage by rotating the carriage by a rotor, and dispense the paper mediums to one of a plurality of dispenser portions by the carriage moving along movement paths. In addition, since a discharge path for paper medium being discharged from a rejected medium transfer portion to a collected medium storage portion and a discharge path for paper medium being discharged from the carriage to the collected medium storage portion are formed in a common discharge space, paper mediums detected to be abnormal and rejected and paper mediums not received by the dispenser portions but retracted may be stored in one place. Consequently, the structure may be simplified.
