  • Patent number: 6402529
    Abstract: The first card accommodating portion for accommodating the first card and the second card accommodating portion for accommodating the second card are formed in the connector housing in such a way that a part of the first and second card accommodating portions can be used commonly by the first and second cards. This construction allows two or more kinds of cards with different external shapes and different contact pad positions to be inserted into the connector from one and the same card insertion slot, thus reducing the space occupied by the card connector.

  • Patent number: 5905253
    Abstract: A memory card is to be inserted into an electronic device so as to add a memory function. The memory card comprises a parent card and a child card, the child card including a semiconductor memory element and a lead as an external terminal of the memory element. The parent card includes a child card receiving portion and a child card insert port for inserting the child card into the child card receiving portion through the child card insert port, and a contact to be contacted with the lead of the child card within the child card receiving portion. A contact opening/closing slide plate is provided for causing a contacting portion of the contact to be shifted to a position in which it can contact with the lead while moving in the child card insert direction pushed by the child card. The parent card also includes a connector element for contacting with the electronic device.
