An IC card connector is provided which comprises a fixed frame, electrode pieces attached to the fixed frame so as to form contact portions, a moving frame having a holding portion in which the IC card is inserted and held and a window from which each of the electrode terminals of the IC card is exposed when the IC card is inserted into the holding portion, and a support mechanism for supporting the moving frame on the fixed frame. The support mechanism acts to allow the moving frame to rotate between a first position, at which each of the electrode terminals of the IC card inserted into the holding portion of the moving frame is brought into contact with the contact portions of each of the electrode pieces through the window of the moving frame, and a second position, at which the contact between each of the electrode terminals and the contact portion of each of the electrode pieces is broken by the rotation of the moving frame to a position which is at a certain angle with respect to the fixed frame.
