Abstract:
A keyboard apparatus including a key module and a detection circuit is provided. The key module includes a plurality of keys, a plurality of scan lines, and a plurality of return lines. The scan lines and the return lines are crossed to each other and coupled to the keys respectively. The detection circuit is coupled to the return lines and configured to detect a current flowing through each of the return lines and indicate that a switch of each of the keys is in an on state or in an off state according to a value of the current.

Claim (Index 4):
The keyboard apparatus according to  claim 2 , wherein the first voltage terminal is a ground voltage terminal, and the current-to-voltage converter comprises:\n a resistor, coupled between the second terminal of each of the return switches and the ground voltage terminal, and generating a voltage difference between two terminals of the resistor in response to the detection current; and an amplifying circuit, coupled to the two terminals of the resistor to receive the voltage difference, and amplifying the voltage difference to generate the detection voltage.
