Abstract: The present invention provides an inexpensive IC card connector having a mechanism for ejecting an IC card and having an emergency function, wherein, even if a means for automatically unlocking a locking member for ejecting an IC card is disabled due to a fault, the locking member can be unlocked with a simple construction.

Abstract: According to the present invention, in a structure of a connector device for card having a lock-detecting mechanism of a card, a connector device for card capable of surely detecting that the card is locked with a simple structure without increasing the number of parts newly is provided.

Abstract: The present invention provides a card connector having a mechanism for ejecting a card, wherein, without weakening an energizing force of a spring member for energizing a slide member, the card connector can prevent the card from being popped out of the card connector by the energizing force of the spring member and allows the card to be easily taken out.

Abstract: The invention provides a card connector with a card discharging mechanism, in which a data storage card does not exit from the card connector due to the biasing force of a spring member, and in which the card can be easily extracted without weakening the biasing force of the spring member. The card connector includes a housing, an eject arm, a slide member, a return spring, a retaining member and an operation restricting mechanism. The data storage card may be attached and detached to and from the housing. The eject arm engages with the card and is rotatable in the card inserting and discharging directions. The slide member, to which the eject arm is mounted, slides in the card inserting and discharging directions. The return spring biases the slide member in the card discharging direction. The retaining member retains the slide member at a card insertion position against the biasing force of the return spring.

Abstract: In a conventional IC card connector, guide walls provided on side walls of a housing comprise surfaces parallel to each other, and an interval between the guide walls is somewhat greater than a maximum width of a standard of the IC card. If the IC card having the width less than the maximum value of the standard is used, the IC card is greatly slanted due to a large amount of play, and an operation member of a detection switch cannot be operated by the IC card. In an IC card connector of the present embodiment, if the width of the IC card is small, the IC card is supported at sides by vertical surfaces, thus the movement of the IC card in the widthwise direction is regulated. If the width of the IC card is large, the IC card is supported at the side by a slope, thus the movement of the IC card is regulated.

Abstract: An IC card connector device solves a problem with a conventional IC card connector device using two IC cards, the problem being such that two push rods are vertically disposed, leading to higher cost due to more parts incorporated, poor assemblability, and an increased height of the connector device. To eject a first IC card, which has been inserted, a single push rod set in an extended position is pushed to eject the first IC card via a single transmitting pin. To eject a second IC card, a handle is circularly moved with the push rod in the extended position so as to move the transmitting pin from a first heart-shaped cam cutout to a second heart-shaped cam cutout. In this state, the push rod is pressed toward a pushed-in position, which causes the single transmitting pin to circularly move to eject the second IC card.

Abstract: An IC card connector device in which an IC card ejecting operation and a misoperation canceling operation are selectively performed. A frame for guiding an IC card at insertion and extraction is provided with a circulation cam groove and a clearance groove with which a second transmission pin pivotally supported by a pushrod is selectively engaged. By pushing the pushrod after projecting it to a first projecting, a drive plate that is placed in the circulation cam groove is pushed via the second transmission pin, thereby ejecting the IC card. When a misoperation occurs, the second transmission pin is caused to trace the clearance groove, by pulling the pushrod frontward and then pushing the pushrod, thereby canceling an IC card ejecting operation. Furthermore, a handle (actuating element) of the pushrod is provided with a heartshaped cam groove with which a first transmission pin pivotally supported on the frame is engaged.
