Paper sheet handling apparatus

1. A paper sheet handling apparatus comprising:

a transport path that transports a paper sheet one by one;

a recognition unit that recognizes and counts the paper sheets being transported via the transport path; and

a dust tray that is arranged directly under the recognition unit and that receives dust removed from the paper sheet through the recognition unit and fallen down from the recognition unit, and that can be pulled out of the paper sheet handling apparatus.

2. The paper sheet handling apparatus according to claim 1 , further comprising a dust receiving plate that collects the dust present outside the dust tray into the dust tray.

3. The paper sheet handling apparatus according to claim 2 , constituted by a lower unit and an upper unit that can be opened and closed relative to the lower unit,

wherein the dust receiving plate is arranged inside the upper unit.

4. The paper sheet handling apparatus according to claim 3 , wherein the dust receiving plate slants with the upper unit when the upper unit is opened or closed, and the dust receiving plate is arranged at a position where the dust slid down from the dust receiving plate is collected in the dust tray while the dust receiving plate slants.

5. The paper sheet handling apparatus according to claim 2 , wherein the dust tray and the dust receiving plate are arranged under at least a part of the transport path.

6. The paper sheet handling apparatus according to claim 5 , wherein a length of the dust receiving plate in a width direction of the transport path is greater than a width of the transport path in a direction perpendicular to a direction in which the paper sheet is transported.

7. The paper sheet handling apparatus according to claim 5 , wherein the dust receiving plate is arranged under the recognition unit.

8. The paper sheet handling apparatus according to claim 7 , wherein

the recognition unit includes a thickness detection sensor that detects a thickness of the paper sheet, and

at least one of the dust tray and the dust receiving plate is arranged under the thickness detection sensor.

9. The paper sheet handling apparatus according to claim 7 , wherein

the recognition unit includes a magnetic detection sensor that detects magnetism of the paper sheet, and

at least one of the dust tray and the dust receiving plate is arranged under the magnetic detection sensor.

10. The paper sheet handling apparatus according to claim 7 , wherein

the recognition unit includes a thickness detection sensor that detects a thickness of the paper sheet, and

a length of the dust receiving plate in a width direction of the transport path is greater than a length of the thickness detection sensor in the width direction of the transport path in a direction perpendicular to a direction in which the paper sheet is transported.

11. The paper sheet handling apparatus according to claim 7 , wherein

the recognition unit includes a magnetic detection sensor that detects magnetism of the paper sheet, and

a length of the dust receiving plate in a width direction of the transport path is greater than a length of the magnetism detection sensor in the width direction of the transport path in a direction perpendicular to a direction in which the paper sheet is transported.

12. A paper sheet handling apparatus comprising:

a transport path that transports a paper sheet one by one;

a recognition unit that recognizes and counts the paper sheet being transported via the transport path; and

a dust tray that is arranged directly under the recognition unit and has a flat surface.

13. The paper sheet handling apparatus according to claim 12 , further comprising:

a dust receiving plate that is arranged in the vicinity of the dust tray and that has an inclined surface inclined toward the dust tray.
