An electronic card receiving device includes a card holder forming a card receiving space in the device for receiving an electronic card, a card latching mechanism for holding the electronic card in position in the card receiving space formed by the card holder, a contacting mechanism for electrically connecting the device to contacts of the electronic card held in position, and a card pushing mechanism for disconnecting the device from the electronic card and pushing it out of the device. The card pushing mechanism comprises a first ejecting plate and a second ejecting plate slidable in directions of inserting and removing the electronic card. The first ejecting plate comprises an abutting portion for applying a force to an inserted electronic card to push it in the direction of removing the card. The second ejecting plate comprises a stopper guide for obtaining an initial stable condition of the second ejecting plate, a latched condition of the inserted card and a transitional condition of the second ejecting plate during its sliding. When an electronic card is inserted into and removed from the device, an area where card terminals are rubbed by contact pins and time for such a rubbing are very small and short, so that the contact pins are scarcely worn and the card terminals of the electric card are not damaged to ensure high reliability of the system of this kind.
