Abstract
An adapter having female contacts (24) is inserted into a slot provided in an electronic apparatus. The adapter includes a memory card (20) permanently connected to the female contacts, and an opening for receiving an IC card (30). Alternatively, the adapter (80) may use a inductive coil (84) and a circuit unit (83) to interface with a non-contact IC card (50). The latter adapter may include a keyboard (85), display (86), and power supply (87).
Claims11
An adapter for an electronic apparatus, the electronic apparatus comprising a plurality of pins which are connected to female contacts of a memory card device when said emory card device is inserted into a slot of said electronic apparatus to allow data transmission between said memory card device and said electronic apparatus, said adapter being sized to be inserted into said slot, wherein said adapter comprises:

- a slot for inserting an IC card device, said IC card being substantially thinner than said memory card device;
- an interface element for said IC card device which allows data transmission between said adapter and said IC card device;
- and
- a circuit which provides electrical connections between said IC interface element and said female contacts for said adapter.
An adapter for facilitating space-efficient interface with an electronic apparatus having first and second electrical signal interfaces disposed within an end and a side of a slot at one end of a narrow rectangular cavity, said adapter comprising:
- a memory card of a first thickness with an electrical signal interface including female plug contact sockets at one end thereof,
- an IC card of a second thickness less than said first thickness and with an electrical signal interface including conductive surface areas on one side thereof,
- holding means for releasably superimposing and retaining said cards stacked together as a composite unit with their respective electrical signal interfaces exposed at an end and side respectively of the holding means to mate and respectively exchange signals with said first and second electrical signal interfaces of the electronic apparatus when the composite unit is inserted into said slot.
An adapter for facilitating space-efficient interface with an electronic apparatus having an electrical signal interface disposed within a slot at one end of a narrow rectangular cavity, said adapter comprising:
- a housing having an electrical signal interface having female plug contact sockets at one end which matingly connects with electrical signal interface male contacts of the electronic apparatus when the adapter is inserted into said slot;
- said housing including a memory card permanently connected to the female plug contact socket electrical signal interface of the housing;
- said housing including an opening for receiving an IC card therewithin;
- and
- said housing including a coupling circuit for coupling signals between the electrical signal interface of the housing and said IC card when one is present therein, wherein the IC card faces the memory card when the IC card is present in the housing.
An adapter for facilitating space-efficient interface with an electronic apparatus having an electrical signal interface disposed within a slot at one end of a narrow rectangular cavity, said adapter comprising:

- said housing including a circuit board overlying said opening and electrically coupled to the electrical signal interface of the housing;
- said circuit board including an electrical signal interface for coupling signals to and from an IC card when one is present in the opening;
- and
- said circuit board including a keyboard, display and power supply for powering same.
An electronic apparatus comprising:
- a memory card device having female contacts;
- and
- a body having a slot for receiving said memory card device, said body having a plurality of pins in said slot which are connected to said female contacts of said memory card device and allow data transmission between said body and said memory card device when said memory card device is inserted into said slot,
- said memory card device having a holding member for holding, in a superimposed manner, an IC card device which is substantially thinner than said memory card device and has a contact portion,
- said slot, into which said memory card device with said IC card device superimposed thereon is capable of being inserted, having a contact member contacting said contact portion of said IC card device to allow data transmission between said body and said IC card device.
An adapter for an electronic apparatus, the electronic apparatus comprising a plurality of pins which are connected to female contacts of a memory card device when said memory card device is inserted into a slot of said electronic apparatus to allow data transmission between said memory card device and said electronic apparatus, said adapter being sized to be inserted into said slot, wherein said adapter comprises:
