ABSTRACT:
An IC card connector 10 comprises a grounding contact 13, which touches the surface of an IC card first, and a plurality of data-passing contacts 12, which connect with the surface contacts of the IC card after the grounding contact 13 has touched the surface of the IC card. This contact of the grounding contact 13 prior to the connection of the data-passing contacts 12 is made possible by forming the grounding contact 13 higher than the data-passing contacts 12. In an IC card reader/writer equipped with this IC card connector 10, an IC card inserted into the IC card reader/writer is lowered from above the IC card connector 10, so that the grounding contact 13 touches the lower surface of the IC card first. Through this contact of the grounding contact 13 to the IC card, static electricity over the IC card is discharged before the data-passing contacts 12 connect with the surface contacts of the IC card. In this way, an IC card connector and an IC card reader/writer are realized with capability of removing static electricity from the IC card just before the data-passing contacts of the IC card connector connect with the surface contacts of the IC card.
