Abstract
The built-in multifunctional card reader is comprised of a circuit board in a housing as a principal unit; the circuit board is provided with a control circuit formed by connecting among a loop of an externally connecting device, a loop for an integrated circuit and a memory card loop. Wherein the card reader makes separation of the operation voltage of various memory cards in the card reader from the loop of the externally connecting device to maintain the normal operation of the card reader as well as to get an effect of EMI prevention by providing a circuit connector on a circuit board in connecting with a power supplying device to directly make the circuit board supply power for operation of the card reader, and by providing a main signal connector on the circuit board to form connection among the integrated circuit, the memory card loop and the main board, further by providing an auxiliary signal connector in the loop of the externally connecting device to form connection between the externally connecting device and the main board.
