Ink mist type high speed printer

摘要

This invention provides an ink mist type high speed printer in which an aperture board is provided between a first electrode and a second electrode across which a high voltage is applied. The aperture board is adapted to selectively control passage of ions generated from the second electrode, and a stream of ink mist is passed between said aperture board and first electrode so that the ions which have passed said aperture board will electrically charge the ink mist particles selectively to let the electrically charged ink mist particles deposit on a recording paper placed between the ink mist and first electrode to thereby print the desired dot matrix characters. This invention also features provision of electrostatic shields placed between said first electrode and ink mist stream and at places outside of the desired printing space to guard the aperture board against deposition of ink mist particles.
