Abstract
A medium processing apparatus includes a processing unit that performs processing on a sheet-like medium; an outer wall on which a discharge port, from which the medium processed by the processing unit is discharged, is open; a stacking portion that has a stacking surface on which the medium discharged from the discharge port is stacked; a suction unit that sucks air on the stacking surface via a suction port provided below the discharge port; and a control unit that controls a workload of the suction unit. The control unit reduces the workload of the suction unit according to an open area of the suction port which is occluded by the medium stacked on the stacking portion and is decreased.

A medium processing apparatus comprising:
- a processing unit that performs processing on a sheet-like medium;
- an outer wall on which a discharge port, from which the medium processed by the processing unit is discharged, is open;
- a stacking portion that has a stacking surface on which the medium discharged from the discharge port is stacked;
- a suction unit that sucks air on the stacking surface via a suction port provided below the discharge port;
- and
- a control unit that controls a workload of the suction unit to reduce the workload of the suction unit according to a decrease of an open area of the suction port caused by the occlusion of the suction port by the stacked medium on the stacking portion, the open area being compared against one or more predetermined threshold values, the one or more predetermined threshold values specifying a desired workload for the suction unit, the workload of the suction unit being decreased when the open area exceeds the one or more predetermined threshold values.
