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 respectively coupled to the keys. The detection circuit detects a plurality of return voltages of the return lines and generates a plurality of detection signals accordingly so as to indicate that a switch of each of the keys is at an on state or at an off state. The detection circuit includes a plurality of P-type transistors. A first terminal of each P-type transistor is coupled to a ground terminal, a control terminal of each P-type transistor is directly coupled to a corresponding one of the return lines, and a second terminal of each P-type transistor generates and outputs one of the detection signals.

Claim (Index 1):
A keyboard apparatus, comprising:\n a key module comprising a plurality of keys, a plurality of scan lines and a plurality of return lines, wherein the plurality of scan lines and the plurality of return lines are crossed to each other and respectively coupled to the plurality of keys; and a detection circuit coupled to the plurality of return lines for detecting a plurality of return voltages of the plurality of return lines, and generating a plurality of detection signals accordingly so as to indicate that a switch of each of the plurality of keys is at an on state or at an off state, wherein the detection circuit comprises: a plurality of P-type transistors, wherein a first terminal of each of the plurality of P-type transistors is coupled to a ground terminal, a control terminal of each of the plurality of P-type transistors is directly coupled to a corresponding one of the plurality of return lines, and a second terminal of each of the plurality of P-type transistors generates and outputs a corresponding one of the plurality of detection signals, wherein only one P-type transistor is configured to detect each return line.
