Abstract: A method and a device for continuously detecting thickness of a sheet-type medium in a continuous conveying process can achieve a more accurate and stable detected thickness value. The device for detecting thickness of a sheet-type medium comprises a conveying roller; a detection roller, the detection roller being arranged opposite to the conveying roller, and an elastic displacement existing between the detection roller and the conveying roller; a plate spring, arranged by pressing opposite to the other side of the detection roller relative to the conveying roller; a sensor, arranged above the plate spring; and a thickness calculation unit, calculating a thickness value of the sheet-type medium according to a distance detection value and a standard zero value; and further comprises a zero value correction unit.

Abstract: A banknote dispensing/receiving mechanism of a banknote processing device includes a housing and a baffle, the baffle is an elastic retaining piece, the elastic retaining piece has one end fixed with respect to the housing and another end being a free end, and the elastic retaining piece is located in the discharging route of banknotes. When the banknote dispensing/receiving mechanism operates, after the banknotes being discharged by a banknote-dispensing conveying mechanism, the banknotes fall onto the elastic retaining piece, and the elastic retaining piece provides a supporting force for the banknotes. When all the banknotes are discharged, the banknotes are pushed by a banknote pushing plate to apply a pushing force to the elastic retaining piece, and at this moment the elastic retaining piece generates a plastics deformation, which makes the banknotes and the banknote pushing plate pass through the elastic retaining piece together, to further perform subsequent operations.
