Abstract
PURPOSE:To prevent clogging of an ink jet port by providing an ink-on-demand type ink jet head with a means which jets ink from the port when ink jetting has been interrupted for a predetermined time period. CONSTITUTION:A typewriter is provided with an ink-on-demand type ink jet head 6 wherein pressure variations are fed to ink 3 through utilization of the electromechanical transducing action of a piezoelectric element 2 so as to jet the ink 3 from an ink jet port 4 for conducting printing. The device is provided with a means which feeds a coil L with current, displaces the head 6 to a position where unnecessary ink can be disposed, and jets the ink 3 from the port 4 when the operation of a keyboard 9 and/or the feed of printing signals from a character generator 10 has been interrupted for a predetermined time period and ink jetting from the port 4 has been interrupted for a predetermined time period. By this clogging of the port 4 by the ink 3 is prevented.
