Patent ID: 7335036

Claim:
A memory card reader comprising: a case including a first end having a coupler with a compartment, with the first end of the case being adapted to couple with a coupling opening of a USB socket, with the case further including a second end having a card receiving space in communication with the compartment, with the card receiving space including an insertion opening and being adapted for receiving a memory card through the insertion opening; and an adaptor circuit board mounted in the compartment and the card receiving space, with the adaptor circuit board including a side having a first end with a USB interface and a second end with a plurality of resilient conductive plates, with the USB interface of the adaptor circuit board facing the compartment of the coupler and being adapted for engaging with a coupling seat in the coupling opening of the USB socket and adapted to be in contact with a plurality of resilient conductive plates in the coupling seat, with the resilient conductive plates of the adaptor circuit board facing the card receiving space and being adapted to be in contact with a read/write interface of the memory card, and with the case being made of insulating plastic, with the coupler integrally extending outward from the case, with a coupling opening being defined in an end of the coupler, with the compartment including an extension groove extending into a lower portion of the card receiving space, with the case including a stepped portion defining an end of the extension groove, and with the adaptor circuit board being mounted in the compartment and the extension groove.
