Direct printing apparatus

摘要

The present invention provides a direct printing apparatus reducing the number of driver IC, contemplating cost reduction, increasing a printing speed and preventing aperture clogging. Each aperture (56) has a size allowing the printing particles (38) for a plurality of dots to pass through it. Control electrodes of each aperture (56) comprises a first electrode (68) positioned at the bearing member side and a second electrode (70) positioned at the backing electrode side. The second electrode (70) is divided into a number equivalent to the maximum number of the dots possible to pass through each aperture (56).
