A paper sheet storing apparatus includes: a supply reel that supplies a wound threadlike material; a winding drum around which a paper sheet is wound around together with the threadlike material supplied from the supply reel; and a guide mechanism that guides the threadlike material through a conveyance path between the supply reel and the winding drum.

A banknote stacking device includes an input mechanism configured to convey banknotes one by one, a stacking platform mechanism configured to stack and support banknotes conveyed by the input mechanism one by one a pressing and conveying mechanism located above the stacking platform mechanism and configured to press banknotes and convey the banknotes stacked on the platform forward. The pressing and conveying mechanism has a pressing rod, and the pressing rod has one end rotatably arranged on the upper conveying rotating shaft and another end forming a free end and falling freely towards the platform, the rotatable securing end and the free end of the pressing rod are respectively provided with a first concave wheel and a second concave wheel, and a first O-shaped belt is arranged on the first concave wheel and the second concave wheel. The first concave wheel rotates synchronously with the upper conveying rotating shaft.
