Abstract

PURPOSE:To control the discharging of ink at the time of absence of signal and the sucking of bubbles into an ink chamber, by separating the ink chamber into two sections including an inner chamber, which is provided with a device to increase the pressure, and an outer chamber, which is provided with an air chamber capable of containing gaseous body. CONSTITUTION:In absence of the air chamber 19, when a strong impact is given to a head at such a time as a high-speed scanning of the head, etc., or if variation of ink pressure in an ink feed pipe 9 caused by vibration of the ink feed pipe 9, etc. is conducted to an outer ink chamber 5, air is sucked into an inner ink chamber 3 as bubbles through an ink discharging gate 4 and, on the other hand, the ink in the outer chamber 5 is discharged as drops 12 from an ink discharging gate 6 even at the time when an electric signal 11 is not impressed on an electrostriction element 1. Now, by providing the outer ink chamber 5 with the air chamber 19 and allowing it to suck small volume of bubbles preliminarily, it becomes possible to prevent ink from being discharged when the electric signal 11 is not impressed on the electrostriction element 1, and it is also possible to prevent the outer ink chamber 5 from further sucking of air.
