wherein in a state in which a part of the IC tag is embedded in the rotational member, an other part of the IC tag is protruded from the thrust edge face of the rotational member in a thrust direction, and

wherein by pulling out the other part of the IC tag that is protruded from the thrust edge face of the rotational member in the thrust direction, the IC tag can be separated from the rotational member.

2. The sheet conveyance roller according to claim 1 ,

wherein the IC tag comprises a main body of the IC tag and a sheet-like member that is attached to the main body of the IC tag; and

the part of the sheet-like member is protruded from the thrust edge face of the rotational member.

3. The sheet conveyance roller according to claim 2 ,

wherein the main body of the IC tag is embedded in the thrust edge face of the rotational member adjacent an axis of the rotational member.

4. The sheet conveyance roller according to claim 1 ,

wherein the IC tag is provided at the outer periphery of an axis of the rotational member shaped in a ring.

5. The sheet conveyance roller according to claim 2 ,

wherein the sheet-like member has the same degree of hardness as that of the main body of the IC tag.

6. The sheet conveyance roller according to claim 1 ,

wherein the IC tag is embedded in the area near an axis of the rotational member.

7. The sheet conveyance roller according to claim 1 ,

wherein the IC tag comprises the main body of the IC tag and the sheet-like member that is attached to the main body of the IC tag; and

the part of the main body of the IC tag is exposed from the thrust edge face of the rotational member.

8. The sheet conveyance roller according to claim 1 ,

wherein the IC tag comprises the main body of the IC tag and the sheet-like member that is attached to the main body of the IC tag; and

the part of the sheet-like member is embedded in the rotational member, and the main body of the IC tag is provided at the part that is exposed from the thrust edge face of the rotational member in this sheet-like member.

9. The sheet conveyance roller according to claim 1 ,

wherein the IC tag comprises the main body of the IC tag and the sheet-like member that is attached to the main body of the IC tag; and

the part of the sheet-like member is exposed from the rotational member with the main body of the IC tag embedded in the rotational member.

10. The sheet conveyance roller according to claim 1 ,

wherein the rotational member is formed by a foaming material.

11. The sheet conveyance roller according to claim 1 ,

wherein the rotational member is a rubber roller; and

the IC tag and the rubber roller are integrally molded so that at least part of the IC tag is embedded in the rubber roller.

12. A sheet processing apparatus, comprising:

a sheet conveyance roller according to claim 1 ; and

a writing means of writing the information regarding the state of use of the sheet conveyance roller in the IC tag.

13. The sheet processing apparatus according to claim 12 ,

wherein the information regarding the state of use of the sheet conveyance roller is the number of sheets that are conveyed by the sheet conveyance roller.

14. A sheet conveyance roller, having:

a rotational member that rotates to convey a sheet, wherein the rotational member has an outer peripheral part abutting against a sheet conveyed and a thrust edge face not abutting against a sheet conveyed; and

a unit, having an IC chip, that can wireless communicate and store information,

wherein in a state in which a part of the unit is embedded in the rotational member, an other part of the unit is protruded from the thrust edge face of the rotational member in a thrust direction,

wherein by pulling out the other part of the unit that is protruded from the thrust edge face of the rotational member in the thrust direction, the unit can be separated from the rotational member.
