Abstract: A multiple-in-one memory card insertion seat is used to improve the defects of the connection of an MS Duo memory card or an MS Pro Duo memory card and an adaptor card. A shift of the matched slot to a corresponding MS memory card is toward the first pin of the XD terminal group so that the GND pin of the XD memory card is unconnected.
