To effectively reduce the damage of an IC tag during conveyance.

This IC tag access device comprises a conveying mechanism for conveying paper with the IC tag attached. The conveying mechanism comprises a roller pair 28 rotated while holding the paper to deliver the paper downstream, and a holding condition changing mechanism for changing conditions for holding the paper by the roller pair 28. The holding condition changing mechanism moves a driven roller 42 in the width direction of a conveying path to shift an IC tag position and a paper holding position K by the roller pair 28 in the width direction of the conveying path from each other.
