Abstract

PURPOSE: To enable small size and high speed for the adaptibility, by dividing the matrix into the blocks consisting of basic matrix and knowing the matrix into the blockes consisting of basic matrix and knowing the input position arbitrary through the keyboard of matrix constitution.
CONSTITUTION: The block scanning electrodes BL0WBL3 ar led out from the split blocks B0WB3, and the scanning electrodes Y0WY2 and the sense electrodes X0WX2 are provided. When a pressure is exerted on the area A and the electrode BL0 is selected, the electrode X0 is at zero potential state to tell the block address exerted with the pressure with the scanning of the block electrode and the address of the sense electrode at the same time. Next, selection is made to Y scanning, scanning is made in the order of Y0, Y1, Y2, the level of the electrode X0, and when the electrode X0 is zero potential, the address of the electrode Y can be known from the timing. Thus, the input location arbitrary on the matrix is known by dividing the electrode scanning into block scanning and Y scanning, allowing to obtain small size and high speed performance.
