Abstract: The present invention discloses an improved card reader assembly, and more particularly an improved adapter assembly of a card reader that stacks the components in the space as to achieve the effect of saving the area and volume of the adapter of the card reader. The improved card reader assembly is an improved adapter assembly that includes a card base, and the card base includes a circuit board and at least one slot. The circuit board has a plurality of lead terminals electrically coupled to a memory card that is inserted into the slot; a top cover; and a chip and an oscillating crystal are installed in the adapter body at a position between the top cover and the card base. The chip is situated between the lead terminal of the card base and the slot, and the chip and the oscillating crystal are electrically connected to the circuit board, and a terminal set is installed onto the adapter body and electrically connected to the circuit board and the chip.
