Sheet handling device

A medium handling device, comprising:

• an upper body;
• a lower body located below the upper body;
• a conveyor which conveys a medium in the upper body and the lower body, and has an annular portion in the upper body;
• and
• a processing circuitry which controls operation of the conveyor, wherein
• the upper body has:
• an inlet/outlet unit including a pair of paths consisting of an inlet path through which the medium is taken into the upper body and an outlet path through which the medium is discharged to an outside of the upper body, the inlet/outlet unit being provided to take the medium to be deposited into the upper body or to discharge the medium to be withdrawn to the outside of the upper body via only the pair of paths;
• and
• a recognition circuitry which recognizes the medium having been taken in through the inlet/outlet unit and being conveyed by the conveyor,
• the lower body has:
• a door located at a front portion of the medium handling device;
• two first storages for the medium, the first storages being opposed to each other in a vertical direction;
• and
• a second storage for the medium, the second storage being larger than each of the first storages,
• the conveyor includes a plurality of concaves each having a rectangular shape,
• the plurality of concaves are arranged in a grid pattern along a first direction and a second direction perpendicular to the first direction,
• the conveyor conveys the medium in the first direction, and
• in the second direction,
• a first concave of the plurality of concaves is disposed at a center of the conveyor,
• a second concave of the plurality of concaves is disposed between the center of the conveyor and a left end of the conveyor, and
• a third concave of the plurality of concaves is disposed between the center of the conveyor and a right end of the conveyor.
