PURPOSE:To stabilize discharge of an ink drop by a method wherein a container reversing temporarily ink, a pressure means having resiliency which is installed to a part of a container wall face, and a pressing means which discharges the ink in the container by pressing the pressure means are established. CONSTITUTION:A printing head 2 waits for an opportunity at a home position H, and moves in the direction E by a printing command from a higher rank device to perform printing. Then, by receiving an ink discharging command during standing by, the printing head 2 moves in the direction F to come above an ink reservoir 4. At that time a pressure pawl 9 attached to a downside of a head carrier 1 pushes a pressuring rubber 5 provided onto the ink resevoir down. Ink in the ink resevoir 4 is pressured by this force to be pushed out in the direction B by action of check valves 6a, 6b and consequently, the ink in the head is discharged. A structure of the title ink jetter is simplified thereby, and its volume is reduced. Furthermore, the title ink jetter can be manufactured at a low cost. |
