Abstract
PURPOSE:To stabilize printing of character picture elements and also to facilitate ink replenishment through extracting bubbles by arranging ink run or ink reservoir on the front of pressure chamber for ink feed with a means to control ink liquid for pressurization, depressurization and vibration. CONSTITUTION:A vacuum pump 15 is connected to an ink reservoir 14 arranged on the front to feed ink to a pressure chamber 8 so as to obtain a vacuum condition 17, voltage is applied to an element 18 integral with the ink reservoir 14 to ultrasonic vibration, a cavitation is thus brought about with the internal ink 21, thereby extracting thoroughly the bubbles having arisen at the time of depressurization. Next, ink 9 is fed into the pressure chamber 8 and from injecting it outside by applying pressure with a piezo-electric element 4 on a head, inking conditions can be kept constant as there is no bubble present in the ink 9, and thus general industrial materials can be used for ink tank. From such arrangement, printing of character picture element can be stabilized and the ink replenishment is facilitated as well.
