A medium processing device includes a first, second and third conveyance path, a classification section, a first, second and third switching unit, a first, second and third storage box and a controller. Each of the first, second and third conveyance paths has two ends. One end of the first conveyance path is connected to one end of the third conveyance path. One end of the second conveyance path is connected to the other end of the third conveyance path at a second side of the classification section opposite to the first side. The other end of the first conveyance path is connected to the other end of the second conveyance path. The controller controls the first conveyance path and the second conveyance path so that the first and second conveyance paths are driven independently from each other.

A method including correcting output of an image sensor unit based on correction information of the image sensor unit that captures and discriminates a paper sheet. A apparatus includes an image sensor unit which includes an image capturing element that captures a banknote so as to discriminate the banknote, a controller that controls the image sensor unit, and a first attachment part, to which the image sensor unit is attached to be detachable, and which includes a connection terminal that connects the image sensor unit and the controller with each other, and which is arranged in a conveyance path for conveying the banknote.
