Abstract: A card reader with dual-headed card slot, comprising a main unit, two magnetic heads, a circuit board and a power cord. Near the center part of the main unit are two side walls forming a card slot, on each of the two side walls is an opening and a magnetic head fixing unit. The two magnetic heads are respectively fixed on two spring plates. The spring plates are then fixed to the magnetic head fixing unit on the main unit, so that the front end of the magnetic head is extending through the opening of the main unit to the inside of the card slot; the circuit board is fixed on the outside of one side wall of the main unit, and on a position of which corresponding to the magnetic head is an opening, the opening serves as the space to the extending and retracting movement of the magnetic head during the card reading process, so that the magnetic head will not be jammed, and on the circuit board is a power cord socket, into the power cord socket is inserted a power cord.
