A medium processing device includes a conveyance guide that forms a conveyance path, a reference surface guide that is provided at one side of the conveyance path, a trigger sensor that detects a rear end of the medium in the conveyance direction, a first alignment roller and a second alignment roller for aligning the medium with the reference surface guide. The first alignment roller is provided at the middle, in a width of the conveyance path. The second alignment roller is provided between the reference surface guide and the first alignment roller in the width direction. The second alignment roller is provided at a downstream side of the first alignment roller in the conveyance direction. A space from the first alignment roller to the second alignment roller in the conveyance direction is longer than a space from the trigger sensor to the first alignment roller in the conveyance direction.
