Abstract
PURPOSE: To increase the function small-sized with a simple constitution, by adding the specific information to the electrode position signal selected at the information bit additional circuit and supplying it to the peripheral circuit.
CONSTITUTION: The keyboard 1 of three-electrode constitution is driven with the block scanning control section 2 and Y scanning control section 3, the potential of the sense electrode is detected 4, the detection signal is shaped at the detection signal control section 5, the scanning signal is judged and fed to the scanning control and selection section 6. The control section 6 performs the selection control for the block scanning control section 2, Y scanning control section 3 and selection detecting circuit 4 with the supplied signal, the selected electrode position signal is fed to the information bit additional circuit 7, and the specific information as semi-angle and full-angle is added. Further, the output of the circuit 7 is fed to the I/O interface circuit 8, and the function corresponding to the specific information is fed to the peripheral circuit. Thus, with a simple constitution, small sized unit is made and the function can be increased.
