<p>An information input device includes first and second counting means serially connected so as to be cyclically driven, a matrix circuit having row lines connected to an output from the first counting means and column lines, and a timing count value selecting circuit consisting of a plurality of AND circuits the respective one gate of which is connected to the respective column line of the matrix circuit and the respective opposite gate of which is connected to an output from the second counting means. The timing count value selecting circuit is adapted to select count values of the first and second counting means on a count timing basis by both an output of the column line selected at the intersection crossed by the row line which is selected by the output of the first counting means through the operation of the input key and an output from the second counting means. The information input signal provides a coded information signal from both an output from the timing count value selecting circuit and count outputs from the first and second counting means.</p> |
