8. The medium process apparatus of claim 1 , wherein a spaced distance between the second support part and the state detection unit is L 1 before the medium is supported by the first support part,

a spaced distance between the second support part and the state detection unit is L 2 greater than L 1 while the medium is supported by the second support part, and

a spaced distance between the second support part and the state detection unit is L 1 again after the medium completely passes through the third support part.

9. The medium process apparatus of claim 1 , wherein the state detection unit detects magnetism of the medium.

10. The medium process apparatus of claim 1 , further comprising:

an installation part configured to rotatably support the support unit; and

an elastic member configured to elastically support the support unit,

wherein the support unit comprises:

a shaft disposed on the installation part;

a first extension part extending upward from the shaft; and

a second extension part extending downward from the shaft, the second extension part being supported by the elastic member,

wherein each of the support parts is disposed on the first extension part.

11. A medium process apparatus comprising:

a state detection unit configured to detect a state of a transferring medium; and

a support unit configured to compress the transferring medium toward the state detection unit,

wherein the medium passes between the state detection unit and the support unit,

the support unit contacts the state detection unit before the medium is supported by the support unit,

the support unit is spaced from the state detection unit in a state where the support unit supports the medium, and

the support unit is spaced from the state detection unit when the medium is not disposed between the state detection unit and the support unit in the state where the support unit supports the medium;

wherein the support unit comprises a second support part overlapping the state detection unit, a first support part disposed at a front side of the second support part and adjacent to the second support part, and a third support part disposed at a rear side of the second support part and adjacent to the second support part; and

wherein the first and third support parts do not overlap the state detection unit in a direction perpendicular to a transfer direction of the medium.

12. The medium process apparatus of claim 11 , further comprising a first guide facing the first support part and a second guide facing the third support part, wherein the first guide and second guide are disposed on a transfer path of the medium.

13. The medium process apparatus of claim 11 , wherein the state detection unit detects magnetism of the medium.

14. The medium process apparatus of claim 11 , further comprising:

an installation part configured to rotatably support the support unit; and

an elastic member configured to elastically support the support unit.

15. A financial device comprising:

a transfer path configured to transfer a medium; and

a medium process apparatus configured to detect a state of the medium on the transfer path,

wherein the medium process apparatus comprises:

a state detection unit configured to detect a state of the medium;

a support unit configured to compress the medium toward the state detection unit;

an installation part on which the support unit is rotatably disposed; and
