Abstract
An information holding device comprising a pair of substrates whose opposing surfaces are formed with electrodes on one side and electrodes on the other side so that they may oppose and that opposing parts between the electrodes on the one side and those on the other side may form a matrix as a whole, a dielectric which is held between said pair of substrates, means to change a capacitance of the dielectric in any desired one of the opposing parts, and detection means to simultaneously detect the capacitances of at least two of the opposing parts between the electrodes on the one side and those on the other side.
