Patent attributes
A memory card reader includes a case including a first end with a compartment for coupling with a coupling opening of a USB socket. The case further includes a second end with a card receiving space. The card receiving space includes an insertion opening for receiving a memory card. An adaptor circuit board is mounted in the compartment and the card receiving space. The adaptor circuit board includes a first end with a USB interface and a second end with resilient conductive plates. The USB interface of the adaptor circuit board faces the compartment and is engaged with a coupling seat in the coupling opening of the USB socket and in contact with resilient conductive plates in the coupling seat. The resilient conductive plates of the adaptor circuit board face the card receiving space and are in contact with a read/write interface of the memory card.
