Aligning of banknotes is carried out without using an aligning device. A medium conveyance mechanism includes an upper belt (2) entrained around two rollers (3a, 3b), a lower belt (5) entrained around two other rollers (6a, 6b) and disposed so as to overlap the upper belt (2), and an aligning guide (15) disposed at one side of the upper belt (2) and the lower belt (5) at a distance therefrom, which aligning guide (15) has an inclined surface (16) for carrying out aligning of a banknote and a conveyance reference surface (17) formed at an end side of the inclined surface (16). When the banknote being conveyed abuts the inclined surface (16) of the aligning guide (15) for aligning, one side of the banknote is guided by the conveyance reference surface (17) while the banknote is slipped with respect to the upper belt (2) and the lower belt (5) in a direction orthogonal to a direction in which the banknote is conveyed. |
