Abstract

A memory card includes a card body, an interface terminal and an attachment mechanism for detachably mounting the card to an adaptor of an electronic device. The interface terminal is disposed at a central portion of a major surface of the card body. The attachment mechanism is located at an outer peripheral portion of the card body that surrounds the central portion. The adaptor has a recess whose shape complements that of the major surface of the card body, and socket exposed at a central portion of the bottom of the recess. Thus, the memory card may be inserted face down into the adaptor.

First claim

What is claimed is:

1. A memory card comprising:
a card body having first and second oppositely facing major surfaces, and an outer peripheral side edge interposed between the first and second major surfaces, and an electronic memory enclosed by the card body as sandwiched between the first and second major surfaces of the card body and surrounded by the outer peripheral side edge of the card body;
an interface terminal exposed at a central portion of the first major surface of the card body and electrically connected to the memory;
an attachment mechanism, by which the card is to be detachably connected to an electronic device, disposed at an outer peripheral portion of the first major surface of the card body that surrounds the central portion; and
an auxiliary interface terminal disposed at the outer periphery of the card body.

2. The memory card of claim 1 , wherein the card body has a circular cross-sectional shape.

3. The memory card of claim 1 , wherein the attachment mechanism comprises a hinge pin supported by the card body, and a latch mounted to the hinge pin, and the card body defines a locking groove in the first major surface and in which the latch is received.

4. The memory card of claim 1 , wherein the interface terminal exposed at the first major surface is a first interface terminal of the card, and the card further comprises a second interface terminal exposed at a central portion of the second major surface of the card body and also electrically connected to the memory contained in the card body.

5. The memory card of claim 4 , further comprising a conductor extending in the card body and electrically connecting the first and second interface terminals directly with each other.

6. The memory card of claim 1 , wherein the attachment mechanism comprises at least one magnet.

7. The memory card of claim 6 , wherein the attachment mechanism comprises a pair of the magnets disposed symmetrically with respect to the interface terminal.

8. The memory card as claimed in claim 1 in combination with an electronic device,
wherein the electronic device comprises a memory card adaptor configured to receive the memory card,
the memory card adaptor comprises an adaptor body having an upper surface and a card-receiving recess in the upper surface, an electrical socket exposed at a central portion of a surface of the adaptor body that defines the bottom of the card-receiving recess, and a lock integral with the adaptor body and disposed at an outer peripheral portion of the upper surface of the adaptor body that defines the bottom of the card-receiving recess,
the card-receiving recess has a cross-sectional shape corresponding to the shape of the first major surface of the card body of the memory card, and the memory card is received in the card-receiving recess with the first major surface of the card body facing the bottom of the card-receiving recess,
the lock and the attachment mechanism coact to detachably secure the memory card to the adaptor body within the card-receiving recess, and
the socket electrically conductively contacts the interface terminal of memory card.

9. The combination of claim 8 , wherein the memory card and the card-receiving recess of the adaptor are each cylindrical.

10. The combination of claim 8 , wherein the attachment mechanism comprises at least one magnet.

11. The combination of claim 8 , wherein the attachment mechanism of the memory card comprises a hinge pin supported by the card body, and a latch mounted to the hinge pin, and the lock of the adaptor comprises a tab at the bottom of the card-receiving recess.

12. The combination of claim 8 , wherein the memory card is a lower memory card and further comprises a second interface terminal exposed at a central portion of the second major surface of the card body and also electrically connected to the memory contained in the card body, and further comprising an upper memory card received in the card-receiving recess of the adaptor body and stacked on the lower memory card, and wherein the upper memory card has an interface terminal electrically conductively contacting the second interface terminal of the lower memory card, and an attachment mechanism that detachably secures the upper memory card to the lower memory card.

13. The combination of claim 12 , further comprising a conductor extending in the card body of the lower memory card and electrically connecting the interface terminals of the lower memory card directly with each other.

14. A memory card comprising:
a card body containing an electronic memory of the card, the card body having first and second oppositely facing major surfaces, and an outer peripheral side edge interposed between the first and second major surfaces;
an interface terminal exposed at a central portion of the first major surface of the card body and electrically connected to the memory; and
at least one magnet, by which the card is to be detachably connected to an electronic device, disposed at an outer peripheral portion of the first major surface of the card body that surrounds the central portion.

15. The memory card of claim 14 , wherein the at least one magnet comprises a pair of the magnets disposed symmetrically with respect to the interface terminal.

16. The memory card as claimed in claim 14 in combination with an electronic device,
wherein the electronic device comprises a memory card adaptor configured to receive the memory card,
the memory card adaptor comprises an adaptor body having an upper surface and a card-receiving recess in the upper surface, an electrical socket exposed at a central portion of a surface of the adaptor body that defines the bottom of the card-receiving recess, and a lock integral with the adaptor body and disposed at an outer peripheral portion of the upper surface of the adaptor body that defines the bottom of the card-receiving recess,
the card-receiving recess has a cross-sectional shape corresponding to the shape of the first major surface of the card body of the memory card, and the memory card is received in the card-receiving recess with the first major surface of the card body facing the bottom of the card-receiving recess,
the lock comprises at least one magnetic element that coacts with the at least one magnet of the memory card to detachably secure the memory card to the adaptor body within the card-receiving recess, and
the socket electrically conductively contacts the interface terminal of memory card.

17. A memory card comprising:
a card body containing an electronic memory of the card, the card body having first and second oppositely facing major surfaces, and an outer peripheral side edge interposed between the first and second major surfaces, and defining a locking groove in the first major surface;
an interface terminal exposed at a central portion of the first major surface of the card body and electrically connected to the memory; and
an attachment mechanism, by which the card is to be detachably connected to an electronic device, disposed at an outer peripheral portion of the first major surface of the card body that surrounds the central portion,
wherein the attachment mechanism comprises a hinge pin supported by the card body, and a latch mounted to the hinge pin and received in the locking groove of the card body.
