Card connector

A card connector having a connector body for removably holding an inserted IC card with a raised surface portion on a back surface side and electric contacts for making electrical contact with the IC card inserted in the connector body, the connector body comprising:

• side portions having card side surface guiding surfaces to guide side surfaces of the inserted IC card;
• a bottom portion having a support surface to support a front surface or back surface of the inserted IC card and stepped portions to engage the raised surface portion formed on the back surface so that the raised surface portion can be moved in an IC card insertion/retraction direction when the back surface of the IC card is supported on the support surface;
• a top plate portion disposed opposite the bottom portion to prevent the inserted IC card from floating upward;
• and
• an urging means provided in the connector body to urge the IC card upward at a predetermined position with respect to the card insertion direction;
• wherein the top plate portion having:
• an under guiding surface disposed to guide the front or the back surface;
• and
• a blocking portion to, when the front surface of the IC card is supported on the support surface, engage the raised surface portion of the IC card at a predetermined blocking position to prevent an incorrectly oriented IC card from being moved forward from the blocking position and prevents the IC card from sliding under the top plate, the blocking portion being disposed in front, with respect to the IC card insertion direction, of the predetermined position where the IC card is urged by the urging means.
