SOLUTION: In a case of a paper sheet being small in size, the paper sheet floats from a conveyance belt 18 and is brought into a state that no conveyance force is exerted. However, it is detected by a paper sheet sensor 35 positioned upper stream from a transfer part that the rear end of the paper sheet 3 is pulled out. After a time in which the paper sheet 3 normally passes a point B of a conveyance passage, a lever member 29 is caused to effect one full rotation at a given timing. Thus, a conveyance force can be exerted on the paper sheet 3, conveyance of which is stagnated, by a lever member 29. |
