Patent ID: 7014121

Claim:
A method of self-detecting and dynamically displaying detected results for a card reader containing at least one card slot used to read flash memory cards, said card reader being internally provided with a control chip for controlling more than one detecting circuit preformed thereon, said self-detecting and displaying method comprising the steps of: A. Causing the control chip to send out a detecting code to each card slot or any flash memory card inserted in said card slot via the detecting circuits, so as to detect a current state of said card slots or said flash memory card inserted in one of said card slots; B. Causing the detecting circuits to send back any detected state code to the control chip, and the control chip to temporarily store the received state code in a state register thereof; C. Sending the state code from the state register of the control chip to a computer, to which the card reader is connected, and clearing all data in the state register; D. Causing a part of the software in the computer to immediately check and determine the state code on receipt of the same, and immediately display a current state of said card slots or said flash memory card on a screen of the computer; and E. Periodically repeating the above self-detecting and displaying steps to present the most current state of said card slots of the card reader or said flash memory card inserted in said card slot.
