Patent number: 10167151Abstract: 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.Type: GrantFiled: May 19, 2016Date of Patent: January 1, 2019Assignee: Oki Electric Industry Co., Ltd.Inventors: Masaaki Okamoto, Wataru Wakushima, Kazuhiro Hosokawa, Satoru Iwasaki, Atsushi Takada

Patent number: 10029881Abstract: 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.Type: GrantFiled: June 15, 2015Date of Patent: July 24, 2018Assignee: Oki Electric Industry Co., Ltd.Inventors: Masaaki Okamoto, Madoka Wakabayashi, Satoru Iwasaki
