At this time, it is desirable that the front surface of the cartridge abut against a stopper wall (not shown) so that forward progress of the cartridge is blocked. Afterward, although the cartridge moves back a small bit by the force of the spring 94, the pull-out-lock protrusion 160 engages in the leak preventing lock indentation 246 at the under surface of the cartridge.

  • the lock releasing operation rib 150 cannot be retracted unless the guide groove 236 is engaged with the guide protrusion wall 120. Therefore, the needle protection plate 130 cannot be retracted so the front surface of the cartridge abuts against the needle protection plate 130 and the ink introducing hollow needle 82 cannot be inserted into the ink supply hole 260.

  • the flexible film 302 deforms in association with reduction in ink without applying pressure to the ink, and the preformed shape of the flexible film 302 substantially follows the tub portion 320 and comes into intimate contact with the tub portion 320. Therefore, the pressure of the ink supplied to the ink jet head 70 can be maintained fairly fixed and ejection of ink from the ink jet head 70 can be stabilized.
  • the amount of remaining ink can be reduced because the flexible film 302 ends up in intimate contact with the tub portion 320, substantially following the tub portion 320. Furthermore, at least a portion of the tub portion 320 is the curved surface portion 324, whose cross-sectional surface area decreases in association with distance from above (the open side) of the tub portion 320. Therefore, the flexible film 302 can easily follow the tub portion 320 when only a little amount of ink remains. The amount of residual ink can be reduced and pressure of the ink supplied is maintained substantially fixed to the very end.
  • the ink cartridge mounting portion S in which the ink cartridge 200 is mounted is positioned lower than the ink jet head 70 in the vertical direction. For this reason, (refer to Fig. 3) the difference in pressure head constantly applies a negative pressure on the ink in the nozzles of the piezoelectric ink jet head 70 in the same manner as a general ink jet recording device. However, under normal conditions the surface tension of the meniscus of the ink in the nozzles maintains the ink in the nozzle against the negative pressure.
  • the positive pressure pump 36 is operated after purge operations until the cap is opened up. Operation of the positive pressure pump 36 can be started during purge operations as well. As a result, the positive pressure air flow is supplied into the atmosphere chamber 290 in the cartridge. A positive pressure is applied to the ink through the flexible film 302.
  • a positive pressure can be applied from the cartridge side to ink in the nozzles of the ink jet head 70 and bubbles can be prevented from being drawn into the nozzles.
  • pressure applied by the positive pressure pump 36 can be a pressure sufficient so that bubbles do not enter the nozzles. Although there is no need to apply a pressure large enough to positively press ink out from the nozzles, such a large pressure can be used.
  • the atmosphere connection hole 280 abuts against the positive pressure application members 91 after the ink introducing hollow needle 82 pierces the ink supply rubber plug 262 in the pull-out-lock protrusion 160.
  • the distance A in the ink cartridge mounting portion S between the needle hole in the ink introducing hollow needle 82 and the front surface of the rubber cap 93 of the positive pressure application member 91 is larger than the distance B that the ink supply rubber plug 262 blocks the inside of the ink supply hole 260 from the front surface of the ink cartridge 200.
  • the atmosphere connection hole 280 would first separate from the positive pressure application members 91 while the ink introducing hollow needle 82 remains in its pierced condition. Therefore, ink can be prevented from leaking out from the ink cartridge 200.

  • the ink cartridge 200 of the present embodiment is configured only from resin parts.
  • the basic configuration of the ink cartridge 200 is a film pulled over a resin case with ink held in between. That is, a single sheet of film is pulled across the tub portion 320 of the main case 230 and ink is filled in between the main case 230 and the film.

  • the main case 230 is made from resin that has a high resistant to dissolving properties of ink.
  • the main case 230 is made from non-additive type polypropylene (PP) which has no additives included therein. If additives were included in the polypropylene, the ink could dissolve the additives because the main case 230 (the ink-holding portion 310) contacts the ink directly.
  • the lid 210 is made from additive-type polypropylene (PP) with additives added for maintaining strength because the lid 210 does not contact the ink directly. In this way, the main case 230 and the lid 210 can be coupled together using ultrasonic welding because both are made from the same resin material (PP).
  • the ink accommodation portion 300 is defined between the tub portion 320 and the flexible film 302.
  • the ink can be used up completely because no foam is used to hold the ink. Because the ink cartridge 200 is made only from resin without using any foam, no dioxin is generated when the ink cartridge 200 is burned after the ink is used up. This reduces adverse influence on the environment from waste materials. Also, there is no need to provide tab portions or a spout as would be required if the ink accommodation portion 300 were a bag shape. Therefore, a large amount of ink can be accommodated in the case with only a small volume.
  • the ink accommodation portion 300 can be prepared with a simple configuration of merely preparing a concave holding vessel and covering it with film. This simple configuration can be easily redesigned as needed.
  • the flexible film 302 is a two-layer configuration. That is, the flexible film 302 is prepared by adhering together an inner layer made from polypropylene (30 ⁇ m thick), which has heat fusing properties, and an outer layer made from nylon, which has heat resistance and shock resistance.
  • the polypropylene (30 ⁇ m thick) is a no-additive type with almost no additives included therein.
