The seat cover is formed with a resilient abutting plate under the projecting section. When the memory card is inserted into the terminal seat, the support arm is pushed and pivoted and the resilient abutting plate abuts against and lifts the projecting section to attach to a depressed face of the press key. When the press key is ejected, the projecting plate is resiliently lifted to engage with the front end of the press key.

Abstract: Extensible/retractable and storable portable memory device including a main body and a sheath. The main body has an adapter at one end. One end of the sheath is formed with an opening for fitting the adapter end of the main body. The other end of the sheath is formed with a through hole through which the adapter can outward protrude. Two sides of the sheath are formed with inward projecting stop boards. The middle portions of two sides of the main body are respectively formed with two lateral projecting blocks. The stop boards stop the lateral projecting blocks from outward sliding so that the main body is restricted to relatively slide within the sheath to extend the adapter out of the sheath or retract the adapter therein and locate the adapter in a predetermined position. Therefore, the memory device can be easily used and carried.

Abstract: Extraction structure of metallic antimagnetic cover. The antimagnetic cover is formed by punching to have an upper cover and a shield body. Multiple bridge sections are formed between the upper cover and the shield body to connect the upper cover with the shield body. A vacuum sucker is used to suck the upper cover to overlay the antimagnetic cover on the chip. Then a hand tool is thrust into the extraction hole of the upper cover for extracting the upper cover from the shield body. Accordingly, the upper side of the chip is open, while the periphery of the chip is shielded by the shield body to isolate the chip from electromagnetic wave.
