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 2):
The keyboard apparatus according to  claim 1 , wherein the detection circuit comprises:\n a selection circuit, coupled to the return lines; and a current-to-voltage converter, coupled between the selection circuit and a first voltage terminal, wherein the selection circuit is controlled by a plurality of selection signals to conduct a current path between the current-to-voltage converter and a selected return line of the return lines, so that the current-to-voltage converter detects the current of the selected return line to serve as a detection current, wherein the current-to-voltage converter converts the detection current into a detection voltage, and accordingly indicates that a switch of each of the keys coupled to the selected return line is in an on state or in an off state.
