a first support plate to support a first media; and

a second support plate to support a second media,

wherein the pick-up roller is disposed between the first support plate and the second support plate, and

when the detection unit detects that a predetermined number of media of one of the first and second media, the pick-up roller unit moves toward a support plate on which the other media are stored.

8. The medium pick-up apparatus of claim 7 , wherein the detection unit comprises:

a first detection unit to detect number of first media; and

a second detection unit to detect number of second media,

wherein the first detection unit detects that a predetermined number of the first media are picked up, the pick-up roller unit moves toward the second support plate.

9. The medium pick-up apparatus of claim 8 , wherein the pick-up roller unit further comprises a position fixing unit to fix a position of the pick-up roller unit in a state in which the pick-up roller unit moves toward the second support plate.

10. The medium pick-up apparatus of claim 9 , wherein, when the second detection unit detects that a predetermined number of the first media are picked up, the pick-up roller unit is released from a position fixed by the position fixing unit, and the pick-up roller unit moves toward the first support plate.

11. The medium pick-up apparatus of claim 1 , wherein the pick-up unit comprises:

a connection member connected to a rotation shaft of the pick-up roller; and

a hook part provided on the connection member,

wherein the pick-up roller moving device moves the hook part.

12. The medium pick-up apparatus of claim 11 , wherein the first power transfer device comprises:

a clutch to receive the power transmitted from the feed roller; and

a power transmission connected to the clutch to transmit the received power to the hook part.

13. The medium pick-up apparatus of claim 12 , further comprising:

a feed roller to transfer the media that are picked up; and

a rotation shaft connected to the feed roller,

wherein the clutch is connected to the rotation shaft of the feed roller.

14. The medium pick-up apparatus of claim 13 , wherein the clutch is turned off while a predetermined number of medium are picked up so that a rotation power of the rotation shaft of the feed roller is not transmitted to the power transmission, and

when the detection unit detects that the predetermined number of media are picked up, the clutch is turned on to transmit the rotation power of the rotation shaft of the feed roller to the power transmission.

15. A medium processing apparatus comprising:

a medium depositing and withdrawing unit through which media are deposited or withdrawn;

a medium storage box to store the media that are deposited or withdrawn; and

a detection unit to detect the media that are deposited or withdrawn,

wherein at least one of the medium depositing and withdrawing unit and the medium storage box comprises:

a pick-up roller for picking up the media stacked in a medium storage space;

a feed roller to transfer the media that are picked up;

a feed roller shaft on which the feed roller is mounted;

a pick-up roller moving device to move the pick-up roller and comprising a first power transfer device to transfer power transmitted from the feed roller shaft to the pick-up roller moving unit; and

a second power transfer device to transfer the power transmitted from the feed roller to the pick-up roller,

wherein, when a predetermined number of media are withdrawn from the medium storage space from the media stored in the medium storage space, an operation of the pick-up roller is stopped and the pick-up roller moving device moves the pick-up roller in a direction away from any remaining media in the medium storage space to prevent the pick-up roller from contacting the remaining media; and

wherein the movement of the pick-up roller by the pick-up roller moving device and the operation of the pick-up roller are stopped at substantially the same time.

16. The medium processing apparatus of claim 15 , further comprising an additional support plate disposed under the pick-up roller to support the media.

17. The medium processing apparatus of claim 16 , wherein, when the detection unit detects that a predetermined number of media are picked up while the media supported by the additional support plate are picked up, the pick-up roller moving device moves the pick-up roller in a direction away from the additional support plate.

18. A financial device comprising:

a customer information acquisition unit to acquire customer information;

a user interface to display a menu or information for depositing or withdrawing, the user interface inputting or selecting a command or information for depositing or withdrawing; and

a medium processing apparatus that stores a medium deposited by a customer and withdraws stored medium for the customer,

wherein, when the medium processing apparatus picks up a predetermined number of media among media stacked in a medium storage space by a pick-up roller to withdraw the picked media from the medium storage space, an operation of the pick-up roller is stopped and the pick-up roller is spaced apart from any remaining media of the media stacked in the medium storage space to prevent the pick-up roller from contacting the remaining media after the predetermined number of media are withdrawn from the medium storage space; and

wherein the pick-up roller being spaced apart from any remaining media of the media and the operation of the pick-up roller are stopped at substantially the same time,

wherein the medium processing apparatus comprises:

a feed roller to transfer the media that are picked up;

a feed roller shaft on which the feed roller is mounted;

a pick-up roller moving device to move the pick-up roller and comprising a first power transfer device to transfer power transmitted from the feed roller shaft to the pick-up roller moving unit; and

a second power transfer device to transfer the power transmitted from the feed roller to the pick-up roller.

19. The financial device of claim 18 , wherein the medium processing apparatus comprises:

a support plate to support the medium;

the pick-up roller passing through the support plate in a state in which the pick-up roller is disposed under the support plate to pick up the medium supported by the support plate.
