Abstract
A selection electrode is formed in correspondence with each aperture of an aperture electrode unit, and a data electrode is formed every two or four adjacent apertures on the same plane as the selection electrode. The selection electrodes and the data electrodes are time-divisionally driven by controlling voltages to be applied to these electrodes. Therefore, a high-resolution recording operation can be performed with a small number of driving ICs, and the cost can be reduced.
