Definitions

  • This reference adopts a constitution of comprising a central chamber having a recording core, a first flocculent fiber in contact with the recording core, and a second flocculent fiber having small amount of ink absorbed in the upper atmosphere communicating port side and being less permeable to the ink than the first flocculent fiber, and a closed type ink storing chamber from which the ink can be supplied via a communicating hole to either side of the central chamber.
  • the fundamental constitution effective for the ink jet characteristics is one having a first accommodating chamber which is a negative pressure generating member receiving portion having an atmosphere communicating portion for communicating to the atmosphere as well as receiving a negative pressure generating member, and a second accommodating chamber which communicates to the first accommodating chamber but lies in substantially closed state, and which is an ink storing portion for directly storing the ink to be supplied to the first accommodating chamber (hereinafter referred to as a presupposed constitution).
  • Fig. 6 is a view showing the state of holding the ink in the ink cartridge of Figs. 5A and 5B.
  • Fig. 16 is a plan view showing the constitution of an opening face of the atmosphere communicating portion as shown in Fig. 15.
  • the ink level in the negative pressure generating member receiving portion necessarily decreases because the ink communicating portion communicating to the ink storing portion lies on the bottom of the partition portion 215.
  • the compression of the absorbing member received within the negative pressure generating member receiving portion is difficult to become even in practice, and the decreasing ink level is not necessarily uniform.
  • 105 is an ink communicating member for introducing the ink within the ink jet head unit
  • 106 is a filter provided at the end portion of the ink communicating member 105 for preventing the flow of fine dirts into the ink jet head.
  • the gas-liquid replacement is effected.
  • the groove portion at the end of the gas-liquid replacement side is shallower in depth when leaving father away from the ink communicating portion. Thereby, the introduction of the air into the groove portion is facilitated.
  • Fig. 15 is an enlarged cross-sectional perspective view of the atmosphere communicating portion and its surrounding in this embodiment.
  • Fig. 15 is a view of an opening portion 1151 of the atmosphere communicating port as shown in Fig. 14, as looked from the above.
  • the atmosphere communicating portion 1150 is substantially comprised of a barrel portion 1150a extending from the inside of the first accommodating chamber 1100 to its wall portion and deadlocked near the outer face of the wall portion, as shown in Fig. 14, and an opening portion (opening portion 1151 of the atmosphere communicating port) divided into plural (three in this embodiment) branches from the deadlock portion of the barrel portion 1150a.
  • This opening portion is provided on the outer surface of a housing for the ink tank unit 1000.
  • the present inventors have proposed a construction of holding a slender pin of the mold not to be swung in injection molding a slender and long atmosphere communicating port, as well as effecting the integration (integral molding) of complex shaped parts and preventing the foreign matter from directly entering the inside of the tank vessel through the opening portion of the atmosphere communicating portion disposed on the surface of the product.
  • an adhesive is applied a predetermined thickness in a predetermined region 2405 near the front end face 2300a on the surface of a support 2300, on the applied surface of which a heater board 2100 is secured by adhesive so that its front end face 2100a and a front end face 2300a of the support 2300 are flush.
  • the ceiling plate 2400 is disposed on this heater board 2100 by temporarily joining so that an orifice plate 2400a is disposed in front of both front end faces 2100a and 2300a of the heater board 2100 and the support 2300, as shown in Fig. 14.
  • 2105 is a discharge heater as electrothermal converter provided at a predetermined position on the heater board 2100.
  • 2411 and 2412 are ink flow passage grooves formed on the ceiling plate 2400, and 2421 and 2422 are discharge ports bored by excimer laser on the orifice plate 2400a of the ceiling plate 2400.
  • 300 is a cap which is disposed at a home position contiguous to the blade 401 and movable back and forth in the directions perpendicular to the moving direction of the recording head to make direct contact with the discharge port face, thereby effecting the capping.
  • 403 is an absorbing member provided adjacent the blade 401, which is held, like the blade 401, in the projected form into the course of movement of the recording head.
  • the recovery of the discharge port portion of the recording head with the blade is performed at a predetermined interval not only during the movement of the carriage before and after the recording, but also during the recording.
  • the ink leakage is less likely to occur, because no ink is reserved in the space portion even if the ink runs along the interstice produce by exfoliation or distortion at the angled portion of the negative pressure generating member (ink absorbing member).
