a portion of the brush fixing part is inserted in a gap formed between two neighboring ones of the extensions.
5. The electrostatic discharging apparatus of claim 4 , wherein the portion of the brush fixing part is inserted into the gap formed between the two neighboring extensions, in a direction parallel to an extension direction of the rotation shaft.
6. The electrostatic discharging apparatus of claim 4 , further comprising an elastic ring that surrounds and presses the extensions, thereby fixing the brush fixing parts coupled to the shaft fixing part, to the rotation shaft.
7. The electrostatic discharging apparatus of claim 1 , wherein fixing holes are individually disposed in the rotation shaft and the shaft fixing part, and
fixing pin passes through the fixing holes, respectively, to fix the shaft fixing part to the rotation shaft.
8. The electrostatic discharging apparatus of claim 1 , wherein the brush fixing part comprises:
a first part having an arc shape and contacting the rotation shaft: and
a second part protruding a certain height from the first part and contacting a surface of the brush.
9. The electrostatic discharging apparatus of claim 1 , further comprising adhesive parts that fix the brushes to the brush fixing parts, respectively.
10. The electrostatic discharging apparatus of claim 9 , wherein a portion of the adhesive part is adhered to a surface of the brush, and another portion thereof is coupled to the brush fixing part, thereby fixing the brush to the brush fixing part.
11. The electrostatic discharging apparatus of claim 1 , wherein the electrostatic discharging member comprises a brush fixing part to which the brush is coupled, and
the brush fixing part is fixed to the rotation shaft by an adhesive.
12. A financial apparatus comprising:
a transfer path along which a medium is transferred;
a transfer roller disposed on the transfer path to transfer the medium;
an electrostatic discharging member comprising a brush for removing static electricity generated during the transfer of the medium, wherein the brush being inhibited from contacting the medium during the transfer of the medium; and
a rotation shaft connected to the electrostatic discharging member.
13. The financial apparatus of claim 12 , wherein the transfer roller is connected to the rotation shaft.
14. The financial apparatus of claim 12 , wherein the electrostatic discharging member comprises a plurality of brushes, and
a distance between a center of the rotation shaft and an end of at least one of the brushes is smaller than a radius of the transfer roller.
15. The financial apparatus of claim 14 , wherein the electrostatic discharging member comprises:
a plurality of brush fixing parts to which the brushes are coupled; and
a shaft fixing part for fixing the brush fixing parts to the rotation shaft.
16. The financial apparatus of claim 15 , wherein a portion of the brush fixing part is disposed between the shaft fixing part and the rotation shaft, and
another portion of the brush fixing part is disposed in a gap formed in the shaft fixing part.
17. The financial apparatus of claim 16 , further comprising an elastic ring that presses the shaft fixing part, thereby fixing the brush fixing parts coupled to the shaft fixing part, to the rotation shaft.
