続してなるキーボードマトリツクスにおいて、前
記スイツチ素子に代わつて前記各格子位置に接続
され行信号と列信号との論理積をとるゲート素子
と、一端が前記各ゲート素子の出力端に接続され
他端がプルアツプ抵抗に共通接続されたスイツチ
素子とからなり、前記共通接続端から出力を取り
出すことを特徴とするキーボードマトリツクス。 In a keyboard matrix in which switch elements are connected to each grid position of row lines and column lines, a gate element is connected to each grid position and performs an AND of a row signal and a column signal in place of the switch element; , a switch element having one end connected to the output end of each of the gate elements and the other end commonly connected to a pull-up resistor, and output is taken out from the common connection end.
