Abstract:
A keyboard device includes M driving circuits DC(1)˜DC(M), N transition circuits TC(1)˜TC(N), a control module, M column signal lines C(1)˜C(M), N row signal lines R(1)˜R(N) and M*N key units KU(1,1)˜KU(M,N). The control module performs a scanning process to sequentially scan the M column signal lines C(1)˜C(M) in M scan cycles scan(1)˜scan(M). If the key unit KU(k,x) connected with the k-th column signal line C(k) and the x-th row signal line R(x) is depressed, a scan voltage is transmitted from the k-th column signal line C(k) to the x-th row signal line R(x) through a switch sw(k,x) of the key unit KU(k,x). The transition circuit TC(x) connected with the x-th row signal line R(x) is turned on according to the scan voltage. Consequently, an output voltage Rout(x) from the transition circuit TC(x) has a first voltage level.

Claim (Index 3):
The keyboard device as claimed in  claim 1 , wherein the transistor circuit TC(x) comprises an NPN-type bipolar junction transistor BJT(x), wherein a base B(x) of the bipolar junction transistor BJT(x) is connected with the row signal line R(x), an emitter E(x) of the bipolar junction transistor BJT(x) is connected with a ground terminal, and a collector C(x) of the bipolar junction transistor BJT(x) is connected with a high supply voltage source and a k-th input port, wherein when the bipolar junction transistor BJT(x) is turned on in the scan cycle scan(k), the transition circuit TC(x) outputs the first voltage level, wherein when the bipolar junction transistor BJT(x) is turned off in the scan cycle scan(k), the transition circuit TC(x) outputs a second voltage level.
