• a bracket mounted on the bottom wall of the housing and defining a receiving chamber having an opening aligning with the card insert slot of the housing;
• an unlock member assembled adjacent to the opening of the bracket and the peripheral wall of the housing;
• and
• a tray detachably assembled to and received within the receiving chamber of the bracket by the unlock member;
• wherein, the tray comprises a supporting portion for receiving a chip card, a draw-off portion formed on a first end of the supporting portion, and a resisting block formed on the draw-off portion and facing toward an opposite second end of the supporting portion;
• the unlock member comprises a main portion, an ejecting portion formed on a first side of the main portion, and an unlock portion formed on one end of the main portion corresponding to the unlock slot;
• the ejecting portion faces toward the card insert slot and slidably resists against the corresponding resisting block of the tray, thereby providing an ejecting force to eject the tray away from the bracket toward the card insert slot;
• the unlock portion passes through the unlock slot and partially exposed to the outside of the housing for driving the unlock member to slide.
