2. The financial device of claim 1 , wherein the controller is configured to control the financial device such that the media stored in the additional function cassette are replenished to the medium storage unit when a number of the media stacked in the medium storage unit is less than the number of the predetermined number of media.

3. The financial device of claim 1 , wherein the discrimination unit recognizes identification information of medium, and

wherein in the audit process, the controller is configured to control the financial device such that the identification information acquired by the discrimination unit is compared to the information stored in the memory.

4. The financial device of claim 1 , wherein the financial device is capable of being operated in a third mode,

wherein in the third mode, the controller is configured to control the financial device such that media discharged from the at least one medium cassette are transferred to the additional function cassette without passing through the discrimination unit.

5. The financial device of claim 4 , further comprising a sensor provided in a transfer path connecting the additional function cassette to the at least one medium cassette to count number of media collected at the additional function cassette.

6. The financial device of claim 1 ,

wherein the financial device is capable of being operated in a fourth mode,

and

wherein in the fourth mode, the controller is configured to control the financial device such that media to be replenished that are stored in the additional function cassette are discharged from the additional function cassette to pass through the discrimination unit and are transferred to and replenished in the at least one medium cassette.

7. The financial device of claim 1 ,

wherein the controller is configured to control the financial device such that a medium that is determined as an abnormal medium by the discrimination unit is stored in the additional function cassette, and

wherein the medium stored in the additional function cassette is transferred to the medium depositing and withdrawing unit after passing through the discrimination unit.

8. The financial device of claim 1 , wherein the lower module further comprises a safe in which the additional function cassette and the medium storage unit are accommodated.

9. The financial device of claim 1 , wherein the medium depositing and withdrawing unit comprises:

a first space into which the media to be counted are accepted;

a first separation part for separating the media in the first space;

a second space in which the counted media are stacked; and

a second separation part for separating the media in the second space,

wherein the counted media stacked in the second space pass through the discrimination unit and are transferred along the transfer path and stored in the medium storage unit to be deposited.

10. The financial device of claim 9 , wherein, in the process of depositing the counted media, the counted media are transferred to the medium storage unit without being temporarily stacked.

11. The financial device of claim 1 , wherein the medium depositing and withdrawing unit comprises:

a first space into which the media to be deposited are accepted;

a first separation part for separating the media in the first space;

a second space in which the media passing through the discrimination unit and temporarily stacked are stacked in the deposit process, and the media passing through the discrimination unit are stacked as media to be withdrawn; and

a second separation part for separating the media in the second space,

wherein the media temporarily stacked in the second space pass through the discrimination unit and are transferred along the transfer path and stored in the medium storage unit.

12. The financial device of claim 11 , wherein the transfer path comprises:

a first transfer path passing through the discrimination unit;

a connection path connecting the first space to the first transfer path; and

a withdrawal path connecting the second space to the first transfer path.

13. The financial device of claim 12 , wherein the transfer path further comprises:

a third transfer path connected to the first transfer path;

a second transfer path connected to the first transfer path and the medium storage unit; and

an entrance path for guiding media in the third transfer path to the second space.

14. The financial device of claim 11 , wherein the medium depositing and withdrawing unit further comprises:

a support surface supporting the media in the second space;

a stack wheel arranged to guide media accepted by rotations thereof to the support surface; and

a medium pressing part inhibiting media from interference in a process where the media are accepted into the second space, the medium pressing part being disposed at a rear side of the media to press the media in the second space while the media in the second space are separated.

15. A financial device comprising:

a medium depositing and withdrawing unit through which media to be counted, media to be deposited, and media to be withdrawn are accepted and withdrawn;

a discrimination unit connected to the medium depositing and withdrawing unit through a transfer path;

a medium storage unit capable of storing media;

an additional function cassette; and

a controller;

wherein, through the additional function cassette and the medium storage unit, the controller is configured to control the financial device to be operated in one of first to third modes;

wherein in the first mode, the controller is configured to control the financial device in a deposit process, such that a predetermined number of media are stacked in the medium storage unit and media that are not stored in the medium storage unit are stored in the additional function cassette;

wherein in the second mode, the controller is configured to control the financial device such that information of the media stored in the medium storage unit is discriminated and then compared to information stored in a memory to perform an audit;

wherein in the third mode, the controller is configured to control the financial device such that the media in the medium storage unit are automatically collected at the additional function cassette and the media in the additional function cassette are replenished into the medium storage unit;

wherein the medium storage unit comprises at least one medium cassette,

wherein in the audit, the controller is configured to control the financial device such that after all the media stored in the at least one medium cassette are transferred to the additional function cassette, the media transferred to the additional function cassette pass through the discrimination unit and are transferred back to the at least one medium cassette; and

wherein the medium depositing and withdrawing unit comprises:

a first space into which the media to be deposited are accepted;

a first separation part for separating the media in the first space;

a second space in which the media passing through the discrimination unit are temporarily stacked in the deposit process, and the media passing through the discrimination unit are stacked as media to be withdrawn;

a second separation part for separating the media in the second space;

a support surface to support the media in the second space; and

a medium pressing part inhibiting the media from interference in a process where the media are accepted into the second space, the medium pressing part being disposed at a rear side of the media to press the media in the second space while the media in the second space are separated;

wherein the media temporarily stacked in the second space pass through the discrimination unit and are transferred along the transfer path and stored in the medium storage unit.
