Abstract
A sheet-type medium stacking device includes a piece-by-piece sheet-type medium conveying mechanism, an upper conveyor belt, an arc-shaped stacking plate, a movable blocking mechanism, a sensor device, and a control unit, wherein at least one pair of convex ribs are formed on a section, close to the conveying mechanism, of the arc-shaped surface of the arc-shaped stacking plate at two sides of the upper conveyor belt, and a distance between the pair of convex ribs is smaller than the minimum dimension of the sheet-type medium in a direction perpendicular to the conveying direction, therefore the sheet-type medium being clamped and conveyed forms a V shape, which greatly increases the rigidity of the sheet-type medium, and effectively solves the problems of blockage caused by the slit at the tail of the sheet-type medium and blockage caused by folding and arching of soft and old medium.
