  • Patent number: 10351373
    Abstract: In a banknote pay-in/pay-out device (10) of an ATM (1), respective pawl portions (42) are provided at upper ends of a front storage box conveyance guide (32) and a rear storage box conveyance guide (33) provided to a front storage box conveyance guide (32) of a banknote storage box (26). In each pawl portion (42), plural pawl bodies (43) are discretely disposed along a left-right direction. In each pawl body (43), a guide plate (51) looking onto a conveyance space (34) is connected to an upper end of a main body (41), a facing plate (52) is connected to an upper-side edge of the guide plate (51), and a left-side plate (53) and a right-side plate (54) are respectively connected to the left and right edges of the guide plate (51). This increases the strength of the guide plates (51) of the pawl bodies (43) such that damage to the pawl bodies (43) as a result of collisions with other members or the like can be prevented, and enables banknotes to be guided smoothly in the banknote pay-in/pay-out device (10).

  • Patent number: 10167151
    Abstract: In a storage box guidance section provided to an upper portion of a banknote storage box in a banknote pay-in/pay-out device of an ATM, a groove is provided running along a front-rear direction at the right side of a storage box conveyance guide group. Further, in a handover section provided to a casing in the banknote pay-in/pay-out device, a position establishing section is provided to the right side of a handover section conveyance guide group. The left-right direction position of the storage box guidance section may accordingly be established with respect to the handover section by positioning the position establishing section inside the groove when storing a lower frame loaded with the banknote storage box and the like in the casing of the banknote pay-in/pay-out device. This enables finger sections of the storage box conveyance guide group and finger sections of the handover section conveyance guide group to be interlocked with each other without abutting.

  • Patent number: 10029881
    Abstract: The present invention provides a medium processing device and medium transaction device that may increase stability by shortening a conveyance path. Namely, a banknote deposit/withdrawal device includes a conveyance section that forms a linear conveyance path along a front-rear direction inside an upper section block, in the vicinity of a boundary with a lower section block. An upper section storage box is disposed in the vicinity of a rear side terminal end of a rear conveyance section. Counterfeit notes are conveyed to the upper section storage box using a switching section. Accordingly, due to keeping the conveyance path length short, the banknote deposit/withdrawal device may reduce the frequency of occurrence of faults, such as banknote jams, and may prevent the circulation of counterfeit notes by storing counterfeit notes segregated from genuine banknotes, reject banknotes, and the like.
