ABSTRACT:
Disclosed is a connecting mechanism for a memory card for connecting a detachable memory card and terminal equipment. The connecting mechanism comprises: a pair of connectors respectively provided on the card side and the terminal equipment side, in which a difference in the length of terminals is provided between a grounding terminal and terminals other than the grounding terminal in such a manner as to establish an electrical sequence in which, during insertion of the memory card, the grounding terminal makes an electrical contact in advance of the other the terminals and is electrically separated by lagging behind the other terminals; a card guide provided on the terminal equipment side and having predetermined dimensions for restricting an angle of inclination of the memory card during insertion or withdrawal thereof so as to obtain the electrical sequence; and a unilateral or bilateral terminal equipment-side buffer circuit provided for all input/output lines excluding a power input line and a grounding line in the terminal equipment, whereby the insertion or withdrawal of activated lines is made possible with respect to the input/output lines excluding a card enable signal line.
